1. Hart WR: Borderline epithelial tumors of the ovary. Mod Pathol; 2005 Feb;18 Suppl 2:S33-50
MedlinePlus Health Information. consumer health - Ovarian Cancer.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Borderline epithelial tumors of the ovary.
  • The concept and terminology of borderline epithelial tumors of the ovary have been controversial for over a century, in spite of the acceptance of a borderline category in almost all current classifications of ovarian tumors.
  • Typically, borderline tumors are noninvasive neoplasms that have nuclear abnormalities and mitotic activity intermediate between benign and malignant tumors of similar cell type.
  • Borderline tumors of all surface epithelial cell types have been studied.
  • Some of the most challenging issues for serous tumors include: the criteria and clinical behavior of stromal microinvasion; the high prevalence of synchronous extraovarian disease; the classification and histopathologic features of associated peritoneal tumor implants, especially invasive implants; and, the prognostic significance of micropapillary tumors.
  • The mucinous borderline tumors of intestinal type have a different set of considerations, including: their frequently heterogeneous composition with coexisting benign, borderline and malignant elements; the classification and significance of accompanying noninvasive carcinoma; the recognition of stromal invasion, including microinvasion and expansile invasion; and, the historically misunderstood relationship to pseudomyxoma peritonei.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Transitional cell carcinoma of the ovary.
  • OBJECTIVE: Transitional cell carcinoma (TCC) of the ovary is a rare, recently recognized, subtype of ovarian surface epithelial cancer.
  • We present a case of TCC of the ovary, managed by staging operation and followed by postoperative chemotherapy with carboplatin and cyclophosphamide.
  • After surgery, the pathologic report of the left ovarian tumor was TCC, grade 2-3, stage IA.
  • CONCLUSION: TCC of the ovary is a rare subtype of epithelial ovarian cancer.
  • It differs from malignant Brenner tumor by the absence of a benign or borderline Brenner component.
  • Surgical resection is the primary therapeutic approach, and patient outcomes after chemotherapy are better than for other types of common epithelial ovarian cancers.

4. Kato N, Sasou S, Motoyama T: Expression of hepatocyte nuclear factor-1beta (HNF-1beta) in clear cell tumors and endometriosis of the ovary. Mod Pathol; 2006 Jan;19(1):83-9
MedlinePlus Health Information. consumer health - Ovarian Disorders.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Expression of hepatocyte nuclear factor-1beta (HNF-1beta) in clear cell tumors and endometriosis of the ovary.
  • Clear cell tumors of the ovary are frequently associated with ovarian endometriosis.
  • Microarray analysis revealed recently that hepatocyte nuclear factor-1beta (HNF-1beta) was significantly upregulated in clear cell carcinoma of the ovary.
  • In the present study, we examined 30 clear cell tumors (26 malignant, three borderline, and one benign) and 40 endometriotic cysts to clarify if differentiation into the clear cell lineage already begins in ovarian endometriosis.
  • All of the 30 clear cell tumors, including borderline and benign ones, showed immunohistochemical expression of HNF-1beta in the nucleus, while other types of ovarian epithelial tumors (endometrioid, serous, mucinous, and Brenner tumors) rarely expressed it.
  • In nine of the 12 cases, distinct nuclear immunostaining for HNF-1beta was detected in the endometriotic epithelium, as well as in the clear cell tumor.
  • Furthermore, 16 of 40 (40%) endometriotic cysts without a neoplasm also expressed HNF-1beta, and the expression was almost exclusively observed in the epithelium showing inflammatory atypia.
  • Our results indicate that HNF-1beta is an excellent molecular marker for ovarian clear cell tumors, including benign, borderline and malignant lesions.
  • Early differentiation into the clear cell lineage takes place in ovarian endometriosis, not only in atypical endometriosis, but also in endometriosis with degenerative and regenerative changes, and this is probably responsible for the frequent occurrence of clear cell carcinoma in ovarian endometriosis.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Canonical and noncanonical Wnt pathway: a comparison among normal ovary, benign ovarian tumor and ovarian cancer.
  • In ovarian cancer, the role played by Wnts and its pathways is not clearly defined.
  • In order to analyze the canonical and noncanonical Wnt pathway in normal ovary, benign ovarian tumor and ovarian cancer, we evaluated the immunohistochemical expression of Wnt1, Frizzled-1 (FZD1), Wnt5a, Frizzled-5 (FZD5) and beta-catenin.
  • Ovarian specimens were obtained from surgeries performed between 1993 and 2004.
  • The patients were divided in three groups: group A, epithelial ovarian cancer (n=38); group B, benign epithelial neoplasia (n=28); and group C, normal ovaries (n=26).
  • Our findings suggest that the pathways related to Wnt5a have an important role in ovarian malignant neoplasia.
  • Furthermore, Wnt5a was found to be a predictor of poor prognosis for ovarian cancer.

  • [Title] Expression profiling of serous low malignant potential, low-grade, and high-grade tumors of the ovary.
  • Papillary serous low malignant potential (LMP) tumors are characterized by malignant features and metastatic potential yet display a benign clinical course.
  • The role of LMP tumors in the development of invasive epithelial cancer of the ovary is not clearly defined.
  • The aim of this study is to determine the relationships among LMP tumors and invasive ovarian cancers and identify genes contributing to their phenotypes.
  • Affymetrix U133 Plus 2.0 microarrays (Santa Clara, CA) were used to interrogate 80 microdissected serous LMP tumors and invasive ovarian malignancies along with 10 ovarian surface epithelium (OSE) brushings.
  • Gene expression profiles for each tumor class were used to complete unsupervised hierarchical clustering analyses and identify differentially expressed genes contributing to these associations.
  • The expression profiles of LMP, low-grade, and high-grade papillary serous ovarian carcinomas suggest that LMP tumors are distinct from high-grade cancers; however, they are remarkably similar to low-grade cancers.
  • Prominent expression of p53 pathway members may play an important role in the LMP tumor phenotype.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Combining multiple serum tumor markers improves detection of stage I epithelial ovarian cancer.
  • OBJECTIVE: Currently available tumor markers for ovarian cancer are still inadequate in both sensitivity and specificity to be used for population-based screening.
  • In this paper, an ANN model was evaluated for its performance in detecting early stage epithelial ovarian cancer using multiple serum markers.
  • The four tumor marker values were then used as inputs to an ANN derived using a training set from 100 apparently healthy women, 45 women with benign conditions arising from the ovary and 55 invasive epithelial ovarian cancer patients (including 27 stage I/II cases).
  • A separate validation set from 27 apparently healthy women, 56 women with benign conditions and 35 women with various types of malignant pelvic masses was used to monitor the ANN's performance during training.
  • An independent test data set from 98 apparently healthy women and 52 early stage epithelial ovarian cancer patients (38 stage I and 4 stage II invasive cases and 10 stage I borderline ovarian tumor cases) was used to evaluate the ANN.
  • At a fixed specificity of 98%, the sensitivities for ANN and CA 125II alone were 71% (37/52) and 46% (24/52) (p=0.047), respectively, for detecting early stage epithelial ovarian cancer, and 71% (30/42) and 43% (18/42) (p=0.040), respectively, for detecting invasive early stage epithelial ovarian cancer.
  • CONCLUSIONS: The combined use of multiple tumor markers through an ANN improves the overall accuracy to discern healthy women from patients with early stage ovarian cancer.

  • [Title] Risk of epithelial ovarian cancer in relation to benign ovarian conditions and ovarian surgery.
  • OBJECTIVE: Some forms of ovarian neoplasms may be preventable through the removal of precursor lesions.
  • We assessed the risk associated with a prior diagnosis of, and ovarian surgery following, ovarian cysts and endometriosis, with a focus on characterizing risk among tumor subgroups.
  • METHODS: Information was collected during in-person interviews with 812 women with ovarian cancer diagnosed in western Washington State from 2002 to 2005 and 1,313 population-based controls.
  • RESULTS: The risk of a borderline mucinous ovarian tumor associated with a history of an ovarian cyst was increased (OR=1.7, 95% CI: 1.0-2.8), but did not vary notably according to receipt of subsequent ovarian surgery.
  • While risk of invasive epithelial ovarian cancer was slightly increased among women with a cyst who had no subsequent ovarian surgery, it was reduced when a cyst diagnosis was followed by surgery (OR = 0.6, 95% CI: 0.4-0.9).
  • Women with a history of endometriosis had a threefold increased risk of endometrioid and clear cell invasive tumors, with a lesser risk increase among women who underwent subsequent ovarian surgery.
  • CONCLUSIONS: Our results suggest differences in the relation of ovarian cysts and endometriosis with risk of specific subtypes of ovarian cancer as well as the possibility that ovarian surgery in women with these conditions may lower the risk of invasive disease.

  • [Title] Chlamydia trachomatis, Mycoplasma genitalium, Neisseria gonorrhoeae, human papillomavirus, and polyomavirus are not detectable in human tissue with epithelial ovarian cancer, borderline tumor, or benign conditions.
  • OBJECTIVE: We sought to analyze the presence of the microorganisms Chlamydia trachomatis, Mycoplasma genitalium, Neisseria gonorrhoeae, human papillomavirus (HPV), and the polyomaviruses BK virus (BKV) and JC virus (JCV) in ovarian tissues of women with ovarian carcinomas, borderline tumors, and benign conditions.
  • STUDY DESIGN: Ovarian tissue, snap-frozen and stored at -80 degrees C, from 186 women with benign conditions, borderline tumors, and epithelial ovarian cancer, as well as tissue from the contralateral ovary of 126 of these women, were analyzed regarding presence of C trachomatis and N gonorrhoeae (transcription mediated amplification), M genitalium (real-time polymerase chain reaction [PCR]), HPV (PCR), and BKV and JCV (PCR).
  • CONCLUSION: C trachomatis, M genitalium, N gonorrhoeae, HPV, and the polyomaviruses BKV and JCV are not detectable in ovarian tissues either from women with benign conditions and borderline tumors or from women with ovarian cancer.

  • [Title] Borderline tumors of the ovary and peritoneal implants.
  • The new WHO series on Pathology and Genetics of Tumours of the Breast and Female Genital Organs (33) defined to name the group of epithelial ovarian tumors with a dignity between benign and malignant exclusively as Borderline Tumors of the Ovary (BOT) and to skip the term "... of low malignant potential".
  • Further, the term "atypical proliferative tumour" was not recommended by the WHO.
  • During a Consensus Meeting on Borderline Tumors of the Ovary held at Bethesda on August 27-28, 2003 (2) the expert panel also recommended to use the BOT terminology.
  • However the term "tumour of low malignant potential" and--less favourable--"atypical proliferative tumour" may be used as synonym.
  • Both groups agreed unanimously that the name carcinoma should not be included in the diagnosis.
  • The group of borderline ovarian tumors is heterogeneous.
  • 80 to 90% of the cases have a very favourable prognosis while 10-20% exhibit a recurrent clinical course with peritoneal implants and very rarely death from the tumor within 10 years.
  • The morphological criteria and supporting methods for recognizing unfavorable BOT and for distinguishing them from highly differentiated ovarian carcinomas are summarized.

  • [Title] Oncofetal protein glypican-3 distinguishes yolk sac tumor from clear cell carcinoma of the ovary.
  • Clear cell carcinoma (CCC) of the ovary is the surface epithelial neoplasm most often confused with primitive germ cell tumors, particularly yolk sac tumor (YST) and dysgerminoma.
  • To investigate whether GPC3 is useful in distinguishing YST from ovarian CCC, we studied the expression of GPC3 in a large series of ovarian neoplasms and compared it to the expression profiles of CK7 and alpha-fetoprotein.
  • Tissue microarrays containing over 400 benign and malignant ovarian neoplasms, including 34 CCCs were stained with monoclonal GPC3 (clone 1G12, Biomosaics, Burlington, VT).
  • These arrays contained a wide assortment of ovarian surface epithelial neoplasms and sex cord stromal neoplasms, as well as germ cell tumors.
  • All but one YST (97%), including those associated with mixed germ cell tumor were positive for GPC3, whereas all teratomas and embryonal carcinomas were negative.
  • All other tissues, including normal ovary were negative for GPC3.
  • GPC3 seems to be a promising diagnostic marker for differentiating YST from ovarian CCC (P < 0.0001).

  • [Title] Cathepsins B and D activity and activity ratios in normal ovaries, benign ovarian neoplasms, and epithelial ovarian cancer.
  • OBJECTIVE: Cathepsins B (CB) and D (CD) belong to a family of proteases felt to be important in tumor metastasis and invasion.
  • It has been suggested that both enzymes play a role the progression of epithelial ovarian cancer and they have been investigated as potential biomarkers for ovarian cancer.
  • METHODS: Ovarian cancer cell lines and snap-frozen archived tissue samples were sonicated and cathepsin activities were assayed fluorometrically with cathepsin-specific peptide substrates in combination with specific inhibitors.
  • Tissue specimens were divided into four groups: normal ovary, benign neoplasm, early-stage (I/II) cancer, and late-stage (III/IV) cancer.
  • CONCLUSIONS: CB activity is associated with invasive ovarian neoplasm.

  • OBJECTIVE: To investigate the expression of the second form of GnRH (GnRH-II) in tumor tissue and peripheral blood mononuclear cells (PBMCs) in malignant and benign ovarian tumors in humans.
  • STUDY DESIGN: Sixty-six women were studied: 24 with epithelial ovarian carcinomas, 22 with benign ovarian tumors and 20 in the control group undergoing surgery.
  • Malignant, benign and normal ovarian tissue and PBMCs were obtained for measurement of GnRH-II mRNA levels using quantitative real-time RT-PCR.
  • RESULT(S): The expression of GnRH-II was found to be 1.5 times higher in malignant ovarian tumors compared with benign ovarian tumors and the control group in post-menopausal patients (P<0.01).
  • In the post-menopausal patient group with malignant ovarian tumors, there were significant positive correlations between serum FSH level and ovarian tissue GnRH-II mRNA expression (r=0.68; P=0.03), and serum LH level and ovarian tissue GnRH-II mRNA expression (r=0.71; P=0.02).
  • Controls, benign and malignant groups were similar in terms of GnRH-II expression in PBMCs in the pre- and post-menopausal periods.
  • There was no significant correlation between ovarian tissue GnRH-II mRNA expression vs. PBMC GnRH-II mRNA expression in patient and control groups.
  • CONCLUSION(S): We have shown increased GnRH-II expression in human ovarian cancer tissue in post-menopausal women in vivo.
  • Expression of GnRH-II in PBMCs did not reflect the local GnRH-II expression levels in ovarian tissue.
  • These preliminary data suggest that local GnRH-II may participate in the regulation of ovarian tumor growth in post-menopausal women.

  • OBJECTIVE: To investigate the expression status of topoisomerase IIIa in epithelial ovarian tumor and the relationship between the expression status of topoisomerase IIIa and pathological type and clinical stage of epithelial ovarian carcinoma.
  • METHODS: Immunohistochemistry was carried out in the samples of ovarian tumor obtained during operation from 169 patients, aged 28 approximately 59, 18 cases with serous cystadenoma, 30 cases with serous borderline cystadenoma, 37 serous cystadenocarcinoma, 10 cases with mucous cystadenoma, 20 mucous borderline cystadenoma, 26 mucous cystadenocarcinoma, 19 cases with endometrial carcinoma of ovary, and 9 cases with clear cell carcinoma.
  • RESULTS: The expression rate of topoisomerase IIIa was 17.9% in the benign ovarian tumors, 74.0% in the borderline cystadenoma, and 42.7% in the malignant tumors with statistical significance among them (chi(2) = 24.657, P < 0.001).
  • CONCLUSION: Topoisomerase IIIa is highly expressed in epithelial ovarian carcinoma, and its expression level is correlated with the character and type of tumor tissues.

  • [Title] Expression analysis and RNA localization of PAI-RBP1 (SERBP1) in epithelial ovarian cancer: association with tumor progression.
  • We present herein for the first time expression analysis of PAI-RBP1 in epithelial ovarian cancer.
  • METHODS: PAI-RBP1 was identified as gene overexpressed in ovarian cancer by an in silico approach using EST database mining.
  • A thorough expression analysis of PAI-RBP1 and PAI-1 was performed in normal ovary (n=4), benign (n=6) and malignant (n=42) ovarian lesions using non-radioactive RNA in situ hybridization and immunohistochemistry, respectively.
  • RESULTS: PAI-RBP1 mRNA and PAI-1 were significantly overexpressed in tumor epithelial cells as compared to benign and normal ovarian tissue.
  • CONCLUSION: In ovarian cancer, PAI-RBP1 is significantly overexpressed in tumor epithelial cells, suggesting a biological role in tumor invasion and metastasis.
  • Its expression is higher in advanced disease, thus the prognostic significance of PAI-RBP1 in ovarian cancer remains to be evaluated in further studies.

  • The vascular tumors occurred most commonly in ovary (six), followed by vulva (two), and one each in cervix and vagina.
  • Clinical diagnoses ranged from cystadenoma in ovarian tumors to endocervical polyp in cervical tumor.
  • Histologically, all were benign vascular neoplasms, ranging from hemangioma (five), lymphangioma (one), lymphangioma circumscriptum (one) to angiomatosis (two) and arteriovenous malformation (one).
  • Thus, we conclude that vascular lesions in FGT can present with symptoms similar to epithelial malignancies and may lead to unwarranted radical surgery.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] [Expressions of osteopontin and B7-H4 in epithelial ovarian neoplasm and their significance].
  • BACKGROUND AND OBJECTIVE: Epithelial ovarian cancer involves a number of factors.
  • Recent studies have shown that osteopontin (OPN) is related to the occurrence and development of a variety of tumors, but few studies are on ovarian cancer.
  • B7-H4 is a newly identified tumor marker in ovarian cancer.
  • This study explored the expression of OPN and B7-H4 and their clinical significance in epithelial ovarian tumors.
  • METHODS: The expression of OPN and B7-H4 in 15 cases of normal ovarian tissue, 20 of benign ovarian tumor tissue, 20 of borderline ovarian tumor tissue, and 40 of ovarian cancer tissue were detected by immunohistochemistry, and the relationship of OPN and B7-H4 expression to clinical and pathologic features of ovarian cancer was analyzed.
  • RESULTS: The expression of OPN and B7-H4 were significantly higher in ovarian cancer than in borderline and benign tumors (P<0.05).
  • The positive rates of OPN and B7-H4 were significantly higher in poorly differentiated ovarian cancer than in medium and highly differentiated ovarian cancer (P<0.05), and the levels of expression were significantly lower in tissue at stages I and III of ovarian cancer than in stages III and IV (P<0.05).
  • The positive rate of B7-H4 were significantly higher in ovarian serous carcinoma than in the mucinous carcinoma (P<0.05), but did not relate to age and lymph node metastasis.
  • CONCLUSION: The expression of OPN and B7-H4 increased in epithelial ovarian cancer, which could be referenced in the diagnosis of ovarian malignant tumors.

  • The purpose of the present study was to determine the expression of phosphorylated AKT (P-AKT) and nuclear factor-kappaB (NF-kappaB) p65 and their association with clinicopathological parameters and prognosis in epithelial ovarian tumor.
  • On immunohistochemistry 115 samples of ovarian tissue that included 68 specimens of epithelial ovarian cancer, 12 of borderline tumor, 24 of epithelial benign tumor and 11 of normal ovary, were evaluated.
  • Sixty-three patients with ovarian cancer were followed up from 7 to 68 months.
  • The positive expression rate of P-AKT and NF-kappaB p65 were higher in epithelial ovarian cancer than in normal ovarian tissue (P<0.01).
  • Elevated expression of P-AKT was negatively correlated with the survival of ovarian cancer patients, but it was not an independent prognostic factor after multivariate analysis.
  • Overexpression of P-AKT and NF-kappaB p65 were involved in the carcinogenesis and metastasis of ovarian cancer.

  • [Title] Raised serum chondroitin sulfate epitope level in ovarian epithelial cancer.
  • OBJECTIVE: To determine the value of serum chondroitin sulfate epitope WF6 and hyaluronan (HA) levels as a biomarker for early detection of ovarian epithelial cancer and other gynecological disorders.
  • METHOD: Serum WF6 CS epitope and HA were measured in 91 patients with ovarian epithelial cancer, 39 patients with non-cancer gynecological disorders and 30 healthy women.
  • RESULTS: The serum concentration of CS (WF6) epitope was highly increased in epithelial types of ovarian cancer and at all stages of development (p < 0.005).
  • Serum HA in ovarian cancer patients was significantly higher than normal controls (p < 0.05).
  • CONCLUSION: These results reflect changes in ECM metabolism in progressive ovarian cancer, which cause an increase in serum CS epitopes and HA.
  • Therefore, serum CS epitopes may provide useful biomarkers for cancers and other disorders of the ovary.
  • Measurement of serum HA provided complementary information, which may be useful as a discriminator between benign ovarian disorders and malignant ovarian diseases.

  • [Title] Prostate-derived Ets factor is overexpressed in serous epithelial ovarian tumors.
  • The frequent overexpression of prostate-derived Ets factor (PDEF) mRNA in ovarian cancer has been previously reported.
  • The aim of this study was to evaluate PDEF protein expression in ovarian cancer and how this expression might vary at different stages of epithelial ovarian tumors in comparison to normal ovary.
  • A new rabbit polyclonal antibody to PDEF was prepared, and immunohistochemistry was performed on tissue sections from 12 normal ovaries, 10 cases of benign serous cystadenoma, 17 cases of low malignant potential tumor, 19 cases of stage 1, and 15 cases of advanced stage primary epithelial (serous) ovarian carcinomas and their peritoneal metastases.
  • All 12 normal ovary and 10 benign serous cystadenoma cases were negative for PDEF expression.
  • In contrast, 6 of 17 (35%) low malignant potential tumors, 5 of 19 (27%) stage 1, and 5 of 15 (33%) advanced stage ovarian tumors stained positive for PDEF expression.
  • Together, these results show frequent overexpression of PDEF protein in epithelial ovarian tumors and its lack of expression in normal ovary and cystadenomas, and this supports a role for PDEF in ovarian tumorigenesis.
  • Furthermore, these results suggest that PDEF is a potential marker and target in ovarian cancer.

  • [Title] Expression and subcellular localization of maspin in human ovarian epithelial neoplasms: correlation with clinicopathologic features.
  • BACKGROUND AND PURPOSE: Maspin is an inhibitor of serine proteinases with tumor suppressor activity that is down-regulated in breast and prostate cancer, but overexpressed in pancreatic carcinoma.
  • However, there were very few published data regarding the role of maspin in ovarian carcinoma.
  • The aim of the present study was to evaluate maspin expression in ovarian epithelial neoplasms and correlate its expression with some clinicopathologic parameters.
  • MATERIAL AND METHODS: Seventy eight paraffin embedded ovarian specimens from patients with ovarian epithelial neoplasms comprised the material of this study.
  • They included 18 benign, 14 low malignant potential (LMP) and 46 malignant epithelial ovarian neoplasms, in addition to seven specimens from normal ovarian tissues as a control.
  • RESULTS: Immunohistochemical study of maspin expression using streptavidin biotin immunoperoxidase method revealed that, normal ovarian surface epithelium did not express maspin as well as benign serous and mucinous ovarian epithelial neoplasm.
  • However, all benign Brenner ovarian tumors were maspin positive.
  • On the other hand, 57.14% of LMP tumors showed weak maspin expression and 63% of malignant ovarian epithelial tumors showed maspin expression with 39.1% over expression.
  • CONCLUSION: Maspin was expressed in a substantial proportion of ovarian tumors with poor prognostic parameters.
  • These results may offer new insights regarding the role of maspin in ovarian cancer that may also impact diagnosis and treatment strategies.
  • Moreover, variation in maspin expression between Brenner tumor and other epithelial surface ovarian tumors may indicate that the different histological types probably represent distinct disease entities and involve different molecular pathways.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Differential expression of aldehyde dehydrogenase 1a1 (ALDH1) in normal ovary and serous ovarian tumors.
  • BACKGROUND: We showed there are specific ALDH1 autoantibodies in ovarian autoimmune disease and ovarian cancer, suggesting a role for ALDH1 in ovarian pathology.
  • However, there is little information on the ovarian expression of ALDH1.
  • Therefore, we compared ALDH1 expression in normal ovary and benign and malignant ovarian tumors to determine if ALDH1 expression is altered in ovarian cancer.
  • Since there is also recent interest in ALDH1 as a cancer stem cell (CSC) marker, we assessed co-expression of ALDH1 with CSC markers in order to determine if ALDH1 is a potential CSC marker in ovarian cancer.
  • METHODS: mRNA and protein expression were compared in normal human ovary and serous ovarian tumors using quantitative Reverse-Transcriptase PCR, Western blot (WB) and semi-quantitative immunohistochemistry (IHC).
  • ALDH1 enzyme activity was confirmed in primary ovarian cells by flow cytometry (FC) using ALDEFLUOR assay.
  • RESULTS: ALDH1 mRNA expression was significantly reduced (p < 0.01; n = 5) in malignant tumors compared to normal ovaries and benign tumors.
  • The proportion of ALDH1+ cells was significantly lower in malignant tumors (17.1 ± 7.61%; n = 5) compared to normal ovaries (37.4 ± 5.4%; p < 0.01; n = 5) and benign tumors (31.03 ± 6.68%; p < 0.05; n = 5).
  • ALDH1+ cells occurred in the stroma and surface epithelium in normal ovary and benign tumors, although surface epithelial expression varied more in benign tumors.
  • Localization of ALDH1 was heterogeneous in malignant tumor cells and little ALDH1 expression occurred in poorly differentiated malignant tumors.
  • In benign tumors the distribution of ALDH1 had features of both normal ovary and malignant tumors.
  • CONCLUSIONS: Total ALDH1 expression is significantly reduced in malignant ovarian tumors while it is relatively unchanged in benign tumors compared to normal ovary.
  • Thus, ALDH1 expression in the ovary does not appear to be similar to breast, lung or colon cancer suggesting possible functional differences in these cancers.
  • SIGNIFICANCE: These observations suggest that reduced ALDH1 expression is associated with malignant transformation in ovarian cancer and provides a basis for further study of the mechanism of ALDH1 in this process.

  • This study was to investigate the expression and significance of P53, P21WAF1 and CDK1 proteins in epithelial ovarian cancer.
  • METHODS: The expression of P53, P21WAF1 and CDK1 proteins in 20 specimens of normal ovarian tissues, 20 specimens of benign epithelial ovarian tumor and 76 specimens of epithelial ovarian cancer was detected by immunohistochemistry.
  • Their correlations to the clinicopathologic characteristics of epithelial ovarian cancer and their interrelationships were analyzed.
  • RESULTS: Significant differences were noted in the positive rates of P53, P21WAF1 and CDK1 proteins between epithelial ovarian cancer and normal ovarian tissues, benign ovarian tumors (P < 0.05).
  • In epithelial ovarian cancer, up-regulation of P53 protein was associated with advanced FIGO stage and poor differentiation; down-regulation of P21WAF1 protein was associated with advanced FIGO stage; CDK1 showed no association with any clinicopathologic factors.
  • CONCLUSIONS: P53 protein is related to the malignancy of epithelial ovarian cancer, P53 and P21WAF1 protein may be related to the malignant development of epithelial ovarian cancer.
  • CDK1 detection may be helpful in the early diagnosis of epithelial ovarian cancer.

  • BACKGROUND: Transformation of a cystic benign teratoma of the ovary into a "carcinosarcoma" has very rarely been reported and its histogenetic origin is still debated.
  • The tumor showed cystic areas delimited by normal squamous epithelium, with transitional areas through dysplastic epithelium to "in situ" and infiltrating squamous cell carcinoma (SCC).
  • Positive staining for vimentin, alpha smooth muscle actin and CD10, as well as P53 and P63, was found in the sarcomatous component and in some atypical basal cells of the squamous epithelium, which also showed the usual epithelial markers.

  • [Title] Factors influencing the use and accuracy of frozen section diagnosis of epithelial ovarian tumors.
  • OBJECTIVE: The objective of the study was to study factors influencing the use and accuracy of frozen section diagnosis (FSD) of ovarian tumors.
  • STUDY DESIGN: Surgery was performed in 414 patients with epithelial ovarian tumors between 2001 and 2006.
  • RESULTS: FSD was requested in 274 patients: 152 benign, 55 borderline, and 67 malignant tumors.
  • Age 50 years or older, tumor size 10 cm or greater, and preoperative evidence of malignancy were associated with FSD request.
  • The sensitivity and specificity of FSD for benign, borderline, and malignant tumors were 97% and 81%, 62% and 96%, and 88% and 99%, respectively.
  • The histologic type (mucinous), tumor size (less than 10 cm), the borderline component (less than 10%), and the pathologist's experience predicted misdiagnosis of borderline tumors.
  • Spread outside the ovary was the only significant predictor of accurate FSD of malignant tumors.
  • CONCLUSION: FSD is less accurate for borderline than benign and malignant ovarian tumors.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Risk factors for benign, borderline and invasive mucinous ovarian tumors: epidemiological evidence of a neoplastic continuum?
  • OBJECTIVE: Some molecular and histological evidence suggests that mucinous epithelial ovarian cancers develop via a sequence from benign tumor through borderline tumor to invasive cancer.
  • Such a sequence would predict some shared risk factors between the different tumor types.
  • To investigate this, we examined risk factors for benign, borderline and invasive mucinous ovarian tumors.
  • Women with benign (n=133), borderline (n=147) and invasive (n=43) mucinous tumors of the ovary and women from the general population (n=1487) completed comprehensive health and lifestyle questionnaires.
  • RESULTS: Although parity was inversely related to risk of benign, borderline and invasive tumors, increasing numbers of births did not further decrease risk of any of the tumor types.
  • However, 20 or more pack-years of smoking was associated with a more than twofold increase in risk of all three tumor types (OR=2.7, 95% CI 1.6-4.4 for benign tumors; OR=2.7, 95% CI 1.7-4.4 for borderline tumors; and OR=2.1, 95% CI 0.9-5.0 for invasive cancers) compared to never smoking.
  • CONCLUSIONS: Overall, the risk factors for mucinous cancers appear to differ from other subtypes of ovarian cancer.
  • Furthermore, patterns of risk factors across benign, borderline and invasive mucinous ovarian tumors are generally consistent with an adenoma-to-carcinoma sequence as the developmental pathway for this subtype of ovarian cancer.
  • Our findings also suggest the potential preventability of borderline and invasive mucinous ovarian cancer by smoking cessation and by surgical excision of identifiable precursor lesions.

  • The aim of this study was to analyze the clinical and prognostic roles of PAI-1 in epithelial ovarian cancer (OC).
  • Tissue sections of paraffin-embedded tumor specimens and fresh-frozen tumor samples from patients with benign and malignant ovarian tumors (OT), who had undergone surgical intervention in the Department of Gynaecology and Obstetrics, Charité, Germany, from 02/01 to 06/02, were used.
  • RESULTS: Sixty-five patients (31 primary OC, 20 recurrent OC, 4 low-malignant potential OT, 6 benign OT, 4 normal ovary) were allocated to this trial.
  • The distributions of (FIGO) tumor stage of all primary OC were: I = 16.1%, II = 3.2%, III = 45.2% and IV = 35.5%.
  • PAI-1 was significantly overexpressed in the tumor epithelium of OC in comparison to the ovarian epithelium of benign OT and normal ovary (p < 0.001).
  • The median PAI-1 level was 1.92-fold higher in malignant OT than in benign OT.
  • In multivariate analysis, only tumor stage (FIGO) (p = 0.003) and residual tumor (p = 0.009) remained independent prognostic factors for post-operative survival.

  • [Title] The origin and pathogenesis of epithelial ovarian cancer: a proposed unifying theory.
  • Ovarian cancer is the most lethal gynecologic malignancy.
  • Efforts at early detection and new therapeutic approaches to reduce mortality have been largely unsuccessful, because the origin and pathogenesis of epithelial ovarian cancer are poorly understood.
  • This has led to the proposal that ovarian cancer develops de novo.
  • Studies have shown that epithelial ovarian cancer is not a single disease but is composed of a diverse group of tumors that can be classified based on distinctive morphologic and molecular genetic features.
  • These tumors generally behave in an indolent fashion, are confined to the ovary at presentation and, as a group, are relatively genetically stable.
  • Moreover, the carcinomas exhibit a shared lineage with the corresponding benign cystic neoplasm, often through an intermediate (borderline tumor) step, supporting the morphologic continuum of tumor progression.
  • Recent studies have also provided cogent evidence that what have been traditionally thought to be primary ovarian tumors actually originate in other pelvic organs and involve the ovary secondarily.
  • Thus, it has been proposed that serous tumors arise from the implantation of epithelium (benign or malignant) from the fallopian tube.
  • As it is generally accepted that endometriosis develops from endometrial tissue by retrograde menstruation, it is reasonable to assume that the endometrium is the source of these ovarian neoplasms.
  • Finally, preliminary data suggest that mucinous and transitional (Brenner) tumors arise from transitional-type epithelial nests at the tubal-mesothelial junction by a process of metaplasia.

  • [Title] Prospective external validation of the 'ovarian crescent sign' as a single ultrasound parameter to distinguish between benign and malignant adnexal pathology.
  • OBJECTIVE: To determine the sensitivity and specificity of the 'ovarian crescent sign' (OCS)-a rim of normal ovarian tissue seen adjacent to an ipsilateral adnexal mass-as a sonographic feature to discriminate between benign and malignant adnexal masses.
  • METHODS: The patients included were a subgroup of patients participating in the International Ovarian Tumor Analysis (IOTA) Phase 2 study, which is an international multicenter study.
  • The gold standard was the histological diagnosis of the adnexal mass.
  • The ability of the OCS to discriminate between borderline or invasively malignant vs. benign adnexal masses, as well as between invasively malignant vs. other (benign and borderline) tumors, was determined and compared with the performance of subjective evaluation of ultrasound findings by the ultrasound examiner.
  • RESULTS: The OCS was evaluated in 1377 adnexal masses from 12 centers, 938 (68%) masses being benign, 86 (6%) borderline, 305 (22%) primary invasive and 48 (3%) metastases.
  • The OCS was present in 398 (42%) of 938 benign masses, in 14 (16%) of 86 borderline tumors, in 18 (6%) of 305 primary invasive tumors (one malignant struma ovarii, one uterine clear cell adenocarcinoma and 16 epithelial carcinomas, i.e. four Stage I and 12 Stage II-IV) and in two (4%) of 48 ovarian metastases.
  • For discrimination between invasive vs. benign or borderline tumors, the sensitivity for absent OCS was 94%, the specificity was 40%, the LR+ was 1.58 and the LR- was 0.14.
  • However it is a poor discriminator between benign and malignant adnexal masses.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Carcinoma of extrahepatic bile ducts and gallbladder metastatic to the ovary: a report of 16 cases.
  • Information on ovarian metastasis of carcinoma of the extrahepatic bile ducts and gallbladder is limited.
  • The patients ranged from 21 to 87 years (mean, 59 years); 7 presented to gynecologists with nonspecific pelvic symptoms similar to primary ovarian neoplasms.
  • The primary tumor was identified before the detection of the ovarian lesions in 5 cases, was simultaneously detected with the ovarian metastases in 9, and was diagnosed postoperatively in 2.
  • All but one case had bilateral ovarian involvement.
  • The thirty-one ovarian lesions included twenty-nine grossly abnormal ovaries that were enlarged (range, 3.0-16.5 cm, mean, 9.4 cm) and 2 ovaries with only microscopic involvement.
  • The sectioned surface was solid in 9, solid-cystic in 15, and multicystic in 5.
  • Microscopically, ovarian surface implants were seen in 66%, multinodular growth in 58%, and infiltrative stromal invasion in 81%.
  • Mucinous epithelial differentiation was seen in 81%, sometimes with foci of benign-like or borderline-like epithelium simulating primary ovarian mucinous neoplasia.
  • Signet ring cells were present in sufficient quantity for a diagnosis of Krukenberg tumor in four tumors.
  • Nonmucinous carcinomatous components included adenocarcinoma with high-grade endometrioid-like morphology in 2 cases, papillary adenocarcinoma simulating mixed müllerian epithelial adenocarcinoma in 1, and undifferentiated carcinoma in 2.
  • The high rate of bilaterality, surface involvement, multinodular growth, and heterogeneity of patterns were the most helpful features for indicating a metastatic nature, with signet ring cells also being helpful in the minority of cases in which they were present.
  • Although the diagnosis of a metastatic tumor to the ovary is possible in most of the cases based on standard diagnostic criteria, problems in the differential diagnosis may be posed by morphologic patterns that overlap strikingly with primary ovarian neoplasms, benign, borderline, and malignant, as discussed herein.

  • [Title] Mac-2 binding protein and galectin-3 expression in mucinous tumours of the ovary: an annealing control primer system and immunohistochemical study.
  • AIM: We used a new differential display method, the annealing control primer (ACP) system, to analyse the differentially expressed genes in mucinous ovarian tumours.
  • To verify the corresponding target gene, immunohistochemical staining was performed on various epithelial tumours of the ovary.
  • METHODS AND RESULTS: The ACP-based reverse transcriptase-polymerase chain reaction revealed that 21 genes were upregulated in the mucinous ovarian adenoma and 14 genes were upregulated in the mucinous ovarian carcinoma.
  • Among them, we selected one upregulated gene, the Mac-2 binding protein (Mac-2 BP), and verified the expression of the Mac-2 BP and its ligand, galectin-3, in a variety of epithelial ovarian tumours by immunohistochemistry.
  • Positive expression of the Mac-2 BP was significantly higher in the mucinous ovarian tumours compared to the other epithelial tumours.
  • Mac-2 BP expression was significantly increased in the borderline and malignant tumours compared to the benign tumours.
  • However, there were no differences in galectin-3 expression in comparisons among benign, borderline and malignant mucinous and serous tumours.
  • CONCLUSION: These data indicate that the Mac-2 BP may play a role in the development and progression of mucinous ovarian tumours.

  • OBJECTIVE: To analyze the expression of phosphorylated protein kinase B (pAKT) and PTEN protein in ovarian epithelial cancer and to investigate the correlations between their expression and prognosis of ovarian epithelial cancers.
  • METHODS: Expression of pAKT and PTEN in 12 normal ovarian tissues, 20 benign tumors, 12 borderline tumors and 80 cases of ovarian epithelial cancers were detected by immunohistochemical method, and their correlations were analyzed.
  • RESULTS: The positive expression of pAKT in normal ovarian and benign tumor tissues were significantly lower than that in ovarian epithelial cancers (8%, 10% vs 55%; P < 0.01), respectively.
  • However, loss of PTEN expression in ovarian epithelial cancers was significantly higher than that in normal ovarian and benign tumor tissues, and the positive rate of PTEN expression were respectively, 45%, 100%, and 80% (P < 0.01).
  • In ovarian cancers, a negative correlation between expression of pAKT and PTEN was observed (r = -0.444, P < 0.01).
  • CONCLUSIONS: The overexpression of pAKT and absence of PTEN are related to ovarian carcinogenesis and development.
  • Loss of PTEN expression is the independent risk factor of poor prognosis in patients with ovarian epithelial cancers.

  • This study investigated the expression patterns of Müllerian inhibiting substance/anti-Müllerian hormone type II receptor (MIS/AMHRII) and mRNA in various types of ovarian neoplasia and evaluated the clinical significance of MIS/AMH as a biological response modifier for MIS/AMHR-positive tumors.
  • There was no significant difference in expression intensity between MIS/AMHRII protein and mRNA on all ovarian samples whether benign or malignant.
  • MIS/AMHRII protein and mRNA were weakly expressed on 45.45% of benign ovarian tumors.
  • In malignant ovarian tumors, expression rates of MIS/AMHRII protein and mRNA were 70% with score 1.23 and 75% with score 1.43, respectively.
  • Among malignant ovarian tumors, sex cord stromal tumors showed the highest expression rate and the strongest intensity of MIS/AMHRII protein and mRNA followed by germ cell tumor and epithelial ovarian tumor.
  • Non-epithelial malignant tumors showed stronger expression than that of epithelial tumors (P<0.05, P<0.001, respectively).
  • In serous borderline malignant and malignant tumors, MIS/AMHRII protein and mRNA expression was 63.64 and 81.82% with expression intensity of 1.27 and 1.46, respectively, which were not statistically different from non-epithelial malignant tumors.
  • MIS/AMHRII and MIS/AMHRII mRNA demonstrate significantly variable expression among different ovarian tumor types.
  • Non-epithelial cell tumors show higher expression than those of epithelial cell tumors.
  • The highest expression rate and intensity were observed on sex cord stromal tumors.
  • These data support that MIS/AMH may be used as a biological modifier or therapeutic modulator in MIS/AMHRII-expressed ovarian tumors.

  • [Title] Toll-like receptor expression in normal ovary and ovarian tumors.
  • Recent studies have implicated inflammation in the initiation and progression of ovarian cancer, though the mechanisms underlying this effect are still not clear.
  • Tumor cell expression of TLRs can promote inflammation and cell survival in the tumor microenvironment.
  • Here we sought to characterize the expression of TLRs in normal human ovaries, benign and malignant ovarian tumors from patients, and in established ovarian tumor cell lines.
  • We report that TLR2, TLR3, TLR4, and TLR5 are strongly expressed on the surface epithelium of normal ovaries.
  • TLR2, TLR3, TLR4, and TLR5 are expressed in benign conditions, epithelial tumors, and in ovarian cancer cell lines.
  • Variable expression of TLR6 and TLR8 was seen in benign and malignant epithelium of some patients, while expression of TLR1, TLR7, and TLR9 was weak.
  • Normal and malignant ovarian stroma were negative for TLR expression.
  • These studies demonstrate expression of multiple TLRs in the epithelium of normal ovaries and in ovarian tumor cells, and may indicate a mechanism by which epithelial tumors manipulate inflammatory pathways to facilitate tumor progression.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Expression and function of HOXA genes in normal and neoplastic ovarian epithelial cells.
  • We studied the roles of three HOXA genes in cultured normal ovarian surface epithelial (OSE) cells and ovarian cancer cells.
  • They included HOXA4 and HOXA7 because, by cDNA microarray analysis, these were more highly expressed in invasive ovarian carcinomas than in benign or borderline (noninvasive) ovarian tumors, and HOXA9 because it characterizes normal oviductal epithelium, which resembles ovarian serous adenocarcinomas.
  • The expression of the HOXA genes varied among ovarian cancer cell lines, but was highest in lines with compact epithelial morphologies.
  • We focused on HOXA4 as the most highly expressed in the ovarian carcinoma array.
  • HOXA4 expression did not parallel proliferative activities of either OSE or ovarian cancer lines.
  • Moreover, modifying HOXA4 expression in ovarian cancer cell lines did not alter either E-cadherin expression or CA125 secretion.
  • However, HOXA4 downregulation enhanced EGFR phosphorylation and migration in serum-starved OSE and ovarian cancer cells in response to EGF, and enhanced migration of all ovarian cancer lines in 5% serum even without EGF treatment.
  • Thus, HOXA4 expression does not correlate with proliferation or with epithelial differentiation, but it increases in response to OSE cell dispersion and negatively regulates EGFR activation and the motility of OSE and of ovarian cancer cells.
  • HOXA4 expression was highest in cancer lines with compact epithelial growth patterns, suggesting, again, an anti-dispersion function.
  • In summary, increased HOXA4 expression in ovarian cancer appears to constitute a tumor-suppressive, homeostatic response to aberrant cell behavior, and, in particular, to cell dispersion and migration.

  • [Title] [Expression of phosphatidylinositol-3 kinase in epithelial ovarian carcinoma].
  • OBJECTIVE: To explore the expression and significance of phosphatidylinositol-3 kinase (PI3K) in ovarian cancer, and the effect of combined PI3K inhibitor (LY294002) therapy with cisplatin on epithelial ovarian carcinoma, and to explore if there is a synergistic effect between the two therapies.
  • METHODS: The expression levels of PI3K p85 subunit proteins and mRNA were evaluated by western blot and RT-PCR in normal ovarian tissue (G1), ovarian benign tumor tissue (G2), ovarian borderline tumor tissue (G3) and ovarian cancer tissue (G4), and the relevant clinical pathological parameters were analyzed.
  • CONCLUSIONS: PI3K p85 subunit is highly expressed and positively correlated with ovarian cancer.
  • Different expression levels exist in tissues of late ovarian cancer, earlier ovarian cancer, borderline tumor, benign ovarian tumor and normal ovarian tissue.
  • The changes in PI3K p85 subunit are correlated with tumor differentiation degree, but not pathologic typing.
  • LY294002 combined with cisplatin can significantly enhance the killing efficiency in ovarian cancer cells.

  • [Title] Brenner tumors of the ovary: sonographic and computed tomographic imaging features.
  • OBJECTIVE: The purpose of this study was to describe the sonographic appearance of ovarian Brenner tumors with computed tomographic (CT) correlation.
  • METHODS: Twenty-two female patients (age range, 32-78 years; mean, 58 years) with 25 ovarian Brenner tumors were identified from pathologic records from 1990 to 2005.
  • RESULTS: Tumors ranged in size from 0.3 to 12 cm (mean, 2.5 cm); all were benign.
  • Eight (36%) of 22 patients had a total of 12 associated benign ovarian neoplasms (1 was contralateral); 3 patients had bilateral Brenner tumors.
  • Four tumors appeared at least partially cystic, of which 3 had coexistent cystic ovarian lesions.
  • CONCLUSIONS: Brenner tumors are most often solid neoplasms found incidentally and frequently seen in association with other benign ovarian epithelial neoplasms.

  • [Title] Expression of serum amyloid a in human ovarian epithelial tumors: implication for a role in ovarian tumorigenesis.
  • Serum amyloid A (SAA) is an acute phase protein which is expressed primarily in the liver as a part of the systemic response to various injuries and inflammatory stimuli; its expression in ovarian tumors has not been described.
  • Here, we investigated the expression of SAA in human benign and malignant ovarian epithelial tumors.
  • Non-radioactive in situ hybridization applied on ovarian paraffin tissue sections revealed mostly negative SAA mRNA expression in normal surface epithelium.
  • Expression was increased gradually as epithelial cells progressed through benign and borderline adenomas to primary and metastatic adenocarcinomas.
  • RT-PCR analysis confirmed the overexpression of the SAA1 and SAA4 genes in ovarian carcinomas compared with normal ovarian tissues.
  • In addition, strong expression of SAA mRNA and protein was found in the ovarian carcinoma cell line OVCAR-3.
  • Finally, patients with ovarian carcinoma had high SAA serum levels, which strongly correlated with high levels of CA-125 and C-reactive protein.
  • Enhanced expression of SAA in ovarian carcinomas may play a role in ovarian tumorigenesis and may have therapeutic application.

  • [Title] Analysis of CD137 and CD137L expression in human primary tumor tissues.
  • AIM: To assess the expression of CD137 and CD137L in human primary tumor tissues and their potential role in tumor immunity.
  • METHODS: Expression of CD137 and CD137L was assessed by immunohistochemistry in frozen sections of 12 human normal tissues, 15 benign tumors of epithelial or mesenchymal origin (adenoma and leiomyoma), and 36 malignant tumors of epithelial origin (squamous cell carcinoma and adenocarcinoma).
  • The expression of CD137L on 9 human tumor cell lines (3 hepatocarcinoma, 2 lung carcinoma, 2 colon carcinoma, 1 lymphoma, and 1 leukemia) was detected by reverse transcription polymerase chain reaction.
  • To analyze the role of CD137L expressed on tumor cells, we co-cultured tumor cells expressing CD137L with activated T lymphocytes expressing CD137 or with Chinese hamster ovary cells expressing CD137 and then detected by ELISA the levels of cytokines (IL-8, IFN-gamma) secreted by tumor cells or activated T cells.
  • RESULTS: The expression of CD137 and CD137L was observed only in human benign (2/15, 3/15) or malignant tumors (15/36, 21/36), but not in normal tissues (0/12, 0/12).
  • CD137 was expressed on the vessel walls within tumor tissues, whereas CD137L was expressed on tumor cells.
  • Furthermore, CD137L expression found on tumor cell lines was functional because the ligation of CD137L on lung squamous carcinoma cells L78 with CD137 on T cells induced IFN-gamma production by T cells, and ligation of CD137L on hepatocarcinoma cells HepG2.2.15 with CD137 triggered tumor cells to produce IL-8.
  • CONCLUSION: CD137 and CD137L are expressed in different human primary tumor tissues, suggesting that they may influence the progression of tumors.

  • [Title] [Expression of glucose transporter-1 and its correlation with basic fibroblast growth factor and proliferating cell nuclear antigen in epithelial ovarian neoplasm].
  • OBJECTIVE: To study the expression of glucose transporter-1 (GLUT1) and its correlation with basic fibroblast growth factor (bFGF) and proliferating cell nuclear antigen (PCNA) in epithelial ovarian neoplasm.
  • METHODS: Streptavidin-peroxidase complex technique was used to examine the expression of GLUT1, bFGF and PCNA protein in six cases of normal ovarian tissue, 20 cases of benign epithelial tumors, seven cases of borderline tumor and 44 cases of epithelial ovarian carcinoma.
  • RESULTS: In normal ovary and benign ovarian tumor, GLUT1 was not detected, but in borderline ovarian tumor and cancer, the positive expression ratio of GLUT1 was 6/7 and 91% (40/44), respectively.
  • The intensity of GLUT1 in ovarian epithelial neoplasm was significantly higher than in borderline tumors.
  • The staining intensity of GLUT1 was significantly correlated with the histological grade of the tumor (r(S) = 0.499, P = 0.001), and was positively correlated with the clinical stage, cancer invasion and lymph node metastasis.
  • bFGF positive rate in tumor was 57% (25/44).

  • [Title] Analysis of the expression of estrogen receptor, progesterone receptor and chicken ovalbumin upstream promoter-transcription factor I in ovarian epithelial cancers and normal ovaries.
  • In the ovary, this role is not clearly defined, with epithelial cancers being poorly responsive to hormone therapy.
  • To investigate the role of these receptors in ovarian carcinogenesis and their implications for cancer prognosis, we evaluated the immunohistochemical expression of ER, progesterone receptor (PR) and COUP-TFI in benign and malignant ovarian epithelial neoplasms and in normal ovaries.
  • A total of 113 ovarian specimens, including 40 diagnosed as malignant epithelial neoplasms (group A), 45 as benign epithelial tumors (group B), and 28 from normal ovaries (group C) were analyzed.
  • Multivariate analysis revealed a residual tumor <1 cm as the most significant clinical prognostic factor in group A (p=0.010, OR=4.14).
  • These data support the importance of cytoreduction in the treatment of ovarian cancer, the role of steroid receptors in the mechanism of carcinogenesis, and the need for selection of subgroups that may respond to hormone therapy.

  • The aim of the present study is to investigate the expression of a novel estrogen receptor, G protein-coupled receptor 30 (GPR30) and its correlation with matrix metalloproteinases-9 (MMP-9) in epithelial ovarian cancer (EOC).
  • Ovary tissues were obtained from 39 female patients, including 30 cases of EOC and 9 cases of benign ovarian tumor.
  • Four normal ovary tissues were used as control.
  • The results showed that GPR30 overexpression rate in EOC cases was significantly higher than those in benign ovarian tumor and normal ovary cases.
  • Whereas MMP-9 overexpression rate in EOC cases was significantly higher than that in normal ovary cases, without any difference to that in benign ovarian tumor cases.
  • These results suggest that GPR30 may be involved in the invasion and metastasis of EOC, being a potential index of EOC early diagnosis and malignancy grade prediction.

  • [Title] Total inhibin is a potential serum marker for epithelial ovarian cancer.
  • CONTEXT: Total inhibin is the sum of precursors, subunits, and mature molecules of inhibin, which the normal ovary nearly stops to produce after menopause, whereas ovarian tumors still release.
  • OBJECTIVE: The aim of the present study was to evaluate whether the serum concentration of total inhibin has the sensitivity/specificity characteristics to become a diagnostic test for epithelial ovarian cancer in postmenopausal women.
  • 1) epithelial ovarian cancer, stage II-III (n = 89);.
  • 2) benign ovarian tumors (n = 25);.
  • In the group of women with epithelial ovarian cancer, blood specimens were also collected after surgical removal of the tumor.
  • In four cases of women with stage IIC mucinous tumor, blood specimens were collected during the follow-up time.
  • RESULTS: Women with epithelial ovarian cancers showed serum total inhibin levels significantly higher than those with benign tumor or with nonovarian tumors or controls (P < 0.001).
  • When total inhibin was combined with CA-125, all cases of serous and mucinous tumors were detected, and the overall sensitivity for epithelial ovarian cancers was 99% at 95% specificity.
  • CONCLUSIONS: The present data show that total inhibin is a sensitive and specific marker of epithelial ovarian cancers in postmenopausal women.
  • Total inhibin may therefore be combined with CA-125 for noninvasive diagnosis of epithelial ovarian cancer and may also be a useful serum marker to monitor disease-free intervals.

  • [Title] Quantitative biochemical analysis of lactate dehydrogenase in human ovarian tissues: correlation with tumor grade.
  • In an attempt to identify glycolytic capacity of normal and neoplastic human ovary, total lactate dehydrogenase (LDH) activity was measured in tissue cytosol originating from 69 patients (18 with benign ovarian tumor, 34 with ovarian carcinoma, six with nonepithelial ovarian malignant tumors, and 11 with tumor metastatic to ovary) and compared to the LDH activity of normal ovarian tissues (n = 19).
  • Median value of total LDH-specific activity expressed as U/mg protein was 0.546 in normal tissues, 0.584 in benign tumors, 1.071 in malignancies metastatic to ovaries, 0.872 in nonepithelial primary ovarian tumors, and 0.818 in primary carcinomas.
  • A significant rise in LDH-specific activity was found in malignant primary and secondary tumors of epithelial and nonepithelial origin, but not in benign neoplasms, compared to the activity in normal tissue.
  • Ovarian carcinomas of serous histologic type did not differ in LDH activity from mucinous tumors.
  • The subgroup of grade 1 tumors did not differ in LDH activity from normal and benign ovarian tissue.
  • Obtained results suggest that direct correlation might exist between ovarian epithelial tumor grade and lactate dehydrogenase activity.

  • [Title] Multicentric infarcted leiomyoadenomatoid tumor: a case report.
  • Adenomatoid tumor is a benign, usually small lesion that may be found within the wall of fallopian tubes or beneath the uterine serosa near the uterine cornu.
  • It is often accompanied by smooth muscle hypertrophy that may obscure the adenomatoid tumor.
  • We herein report a very unusual case of infarcted leiomyoadenomatoid tumor of the uterus and ovary in a 24-year-old woman who presented with severe lower abdominal pain and masses in the uterus and right ovary.
  • Pelvic ultrasonography and computed tomography revealed a 5 cm mass in the myometrium and a 4 cm mass in the right ovary.
  • Laparoscopy-assisted transvaginal mass removal was performed under the clinical impression of a uterine leiomyoma and benign ovarian teratoma.
  • The microscopic appearance often suggested the possibility of a malignant neoplasm due to irregular pseudoinfiltration with atypical cuboidal cells and the paucity of a typical adenomatoid tumor due to infarction, and the presence of epithelial-appearing cells in the hypertrophic smooth muscle bundles that mimicked an infiltrating carcinoma for a leiomyoma or myometrium.

  • A 73-year-old woman was found to have a 22 cm unilateral multilocular mucinous cystic tumor of the ovary.
  • Microscopic examination showed a routine appearance of the epithelial component, which ranged from benign to borderline to low-grade carcinoma.
  • The stromal component was unusual because of a striking cellular theca cell component in the stroma, which, in turn, merged with a component of adult granulosa cell tumor.
  • The "parent" neoplasm in this case and 3 other similar cases in the literature appears to be the mucinous neoplasm, in contrast with the other example of mucinous neoplasia associated with sex cord neoplasia, the Sertoli-Leydig cell tumor with heterologous elements, in which the "parent" neoplasm is likely the Sertoli-Leydig cell tumor.

  • Adriamycin is considered to be an active agent for ovarian cancer.
  • Recently, the benefit of adding adriamycin to the current standard regimen, paclitaxel and platinum, is evaluated to improve the outcome of patients with ovarian cancer.
  • Therefore, we examined the expression of SLC22A16 in ovarian cancers.
  • Twelve ovarian carcinoma cell lines were used for immunoblotting and reverse transcription-polymerase chain reaction to confirm the expression of SLC22A16 mRNA and protein.
  • Five normal ovaries, 12 ovarian adenomas, and 94 ovarian cancer cases were obtained from patients after surgical therapy.
  • The SLC22A16 immunoreactivity was detected in 15 (16%) of 94 epithelial ovarian cancer, 1 (8.3%) of 12 benign adenomas, but 0 (0%) of 5 normal ovary cases.
  • In ovarian cancer tissues, SLC22A16 immunoreactivity was detected in 2 (5%) of 38 serous adenocarcinoma, 1 (6.7%) of 15 endometrioid adenocarcinoma, 0 (0%) of 14 mucinous adenocarcinoma, and 12 (46.2%) of 26 clear-cell adenocarcinoma (P < 0.0001, clear-cell vs other histologies).

  • [Title] Sertoli cell tumors of the ovary: a clinicopathologic and immunohistochemical study of 54 cases.
  • Ovarian Sertoli cell tumors are rare, and their morphologic spectrum, behavior, and factors influencing the latter are not clearly established.
  • Delicate septa were occasionally seen and were conspicuous in areas of one tumor.
  • The cells usually had pale to occasionally densely eosinophilic cytoplasm, but 6 tumors were composed of cells with prominent foamy cytoplasm, falling in the category of "lipid-rich" Sertoli cell tumor, and one had cells with clear non-foamy cytoplasm.
  • Those 3 patients had pelvic-abdominal recurrences 18, 36, and 9 months, respectively, after the initial diagnosis.
  • Two of the three clinically malignant stage I tumors had moderate to severe cytologic atypia and brisk mitotic activity (>5 or more mitoses/10 high power fields [HPFs]), and one of these had tumor cell necrosis.
  • Among the 10 clinically benign stage I tumors with more than 5 years of follow-up, only 3 had >5 mitoses/10 HPFs, but none had more than mild cytologic atypia and none had tumor cell necrosis.
  • Two of the three patients with stage III disease had follow-up information and one was alive at 16 months and the second developed splenic metastases 2 years after the initial diagnosis.
  • Immunohistochemical stains showed positivity for AE1/3-Cam5.2 in 15 of 23 tumors; Epithelial membrane antigen (EMA) was negative in all the tumors.
  • Although Sertoli cell tumors usually have a distinctive tubular pattern that facilitates the diagnosis, other patterns may occasionally predominate, causing confusion with various other primary and metastatic ovarian tumors.
  • EMA, inhibin, and chromogranin represent the most helpful triad of immunomarkers serving to exclude two common mimics of Sertoli cell tumors (endometrioid carcinoma [inhibin-; EMA+; chromogranin-] and carcinoid tumor [inhibin-; EMA+; chromogranin+]).
  • Although CD99 and calretinin are often expressed in these tumors, they are much less specific and not as helpful in the differential diagnosis.
  • Most Sertoli cell tumors are stage I, unilateral, cytologically bland, and clinically benign, but occasional examples are high stage, and about 11% of stage I tumors have worrisome histologic features that may portend an adverse outcome.

  • BACKGROUND & OBJECTIVE: Some studies have showed that changes of autophagic capacity may be correlated to tumorigenesis and tumor development.
  • This study was to investigate the expression of microtubule-associated protein 1 light chain 3 (LC3) and autophagy-related gene Beclin1 in ovarian tumor tissues, and explore their correlations to the tumorigenesis and development of epithelial ovarian carcinoma.
  • METHODS: Expressions of LC3 and Beclin1 in 25 specimens of benign ovarian tumor, 25 specimens of borderline ovarian tumor, and 75 specimens of epithelial ovarian carcinoma were detected by immunohistochemistry.
  • The correlations of LC3 and Beclin1 expression to the clinicopathologic characteristics of the 75 epithelial ovarian cancer patients were analyzed.
  • RESULTS: The positive rates of LC3 and Beclin1 were significantly higher in benign and borderline ovarian tumors than in epithelial ovarian carcinoma (100% and 96% vs. 57%, P<0.001; 100% and 84% vs. 57%, P<0.001).
  • CONCLUSIONS: Expressions of LC3 and Beclin1 are down-regulated in epithelial ovarian cancer tissues.
  • The decrease of autophagic capacity may relate to tumorigenesis and the development of epithelial ovarian cancer.

  • [Title] Differences in expression patterns of the tight junction proteins,claudin 1, 3, 4 and 5, in human ovarian surface epithelium as compared to epithelia in inclusion cysts and epithelial ovarian tumours.
  • Human ovarian surface epithelium (OSE), regarded as the precursor cell of epithelial ovarian adenocarcinoma, is not a fully developed epithelium when situated on the ovarian surface.
  • It lacks epithelial characteristics such as the cell-cell adhesion factor epithelial (E)-cadherin, but as we have shown earlier, this OSE can form functional tight junctions (TJs) in culture.
  • Recent gene-expression data on ovarian adenocarcinoma has pointed out a family of TJ proteins, the claudins, to be highly expressed in malignant compared to benign ovarian tumours.
  • The purpose of this study was to investigate the distribution of claudin 1-5 proteins in cultured OSE (n=4), normal ovarian (n=11), benign (n=8), borderline (n=7) and ovarian cancer (n=22) tissues.
  • We found that a weak or absence of expression of claudin 3 and claudin 4 in surface OSE changed to typical cell-border localisation in OSE of inclusion cysts in the normal ovarian stroma.
  • Semiquantitative estimations of immunoblots showed that claudin 3 was significantly increased in ovarian adenocarcinomas compared to benign and borderline-type tumours.
  • Claudin 4 was significantly increased in both borderline-type and ovarian adenocarcinomas compared to benign tumours, whereas no changes were found for claudin 1 or 5.
  • We conclude that both claudin 3 and 4, even though they differ in expression during ovarian malignant transformation, might be used as novel markers for ovarian tumours.

  • [Title] Clinical applications of microarray technology: creatine kinase B is an up-regulated gene in epithelial ovarian cancer and shows promise as a serum marker.
  • OBJECTIVE:. (1) To identify and (2) validate genes that are up-regulated in ovarian cancer, and (3) to investigate whether the activity of a candidate gene, creatine kinase B (CKB) is elevated in pre-operative sera from ovarian cancer patients compared to patients with benign pelvic masses and normal controls.
  • METHODS: MICROMAX cDNA microarray system and RNA derived from pooled ovarian cancer cell lines and normal ovary surface epithelial cells (HOSE) were used to identify differentially expressed genes.
  • Using a commercially available enzyme assay, CKB activity was measured in pre-operative serum samples obtained from 45 ovarian cancer patients, 49 patients with a benign pelvic mass, as well as 37 normal controls.
  • RNA levels of CKB, measured by real-time PCR, were elevated a mean (and standard error) of 36-fold (8.4) in cancer cell lines compared with HOSE cells and 22.75-fold (10.45) in microdissected ovarian cancer epithelial cells compared with normal ovarian epithelial cells.
  • In serum, the mean (+/-standard error) of CKB enzyme activity in cancer cases was 24.7 U/L units (+/- 5.1) compared to 9.6 U/L (+/- 1.6) for benign mass cases (P = 0.0088) and to 8.5 U/L (1.7) for normal controls (P = 0.0096).
  • CONCLUSIONS: Microarray technology offers a method to identify tumor biomarkers with potential clinical usefulness.
  • Our data indicated that CKB gene expression is up-regulated in ovarian cancer cells in vitro and in vivo and that CKB enzyme activity is significantly elevated in sera from ovarian cancer patients, including those with stage I disease.
  • These findings suggest a potential role for CKB as a marker for early diagnosis.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Use of Ras-transformed human ovarian surface epithelial cells as a model for studying ovarian cancer.
  • The Ras gene family has been implicated in the development of many human epithelial cancers.
  • Mutations in K-ras or its downstream mediator BRAF have been detected in about two thirds of low-grade serous carcinomas and borderline serous tumors; mutations in K-ras are also often present in benign and invasive mucinous ovarian cancers.
  • Although the oncogenic allele H-ras(V12) is present in only approximately 6% of ovarian cancers, physiologically activated H-ras protein is commonly detected in human ovarian cancer, presumably because of an increase in upstream signals from tyrosine kinase growth factor receptors such as Her-2/neu, despite the lack of a Ras mutation.
  • The mechanisms by which ras oncogenes transform human epithelial cells are not clear.
  • The methods described here are what we use to culture human ovarian surface epithelial cells, to immortalize those cells, and to transform the immortalized cells with oncogenic H-ras or K-ras.
  • These Ras-transformed human ovarian surface epithelial cells form tumors in nude mice and recapitulate many features of human ovarian cancer, thus providing an excellent model system for studying the initiation and progression of human ovarian cancer.

  • [Title] High expression of insulin-like growth factor binding protein-2 messenger RNA in epithelial ovarian cancers produces elevated preoperative serum levels.
  • The molecular etiology of epithelial ovarian cancer remains unclear.
  • Using microarray expression analysis, we recently reported that expression of the insulin-like growth factor binding protein-2 (IGFBP-2) gene is elevated in advanced epithelial ovarian cancers.
  • The aim of this study was to further delineate the role of IGFBP-2 in the pathoetiology of epithelial ovarian cancer and determine if elevated ovarian cancer IGFBP-2 gene expression is reflected in serum.
  • Relative IGFBP-2 expression was measured using quantitative real-time polymerase chain reaction in 113 epithelial ovarian cancers and 6 normal ovarian surface epithelial samples.
  • Preoperative serum IGFBP-2 levels were measured by radioimmunoassay in 84 women (42 ovarian cancers, 26 benign gynecological conditions, and 10 healthy female controls).
  • Ovarian cancers demonstrated 38-fold higher mean IGFBP-2 expression than normal ovarian epithelium (P < 0.01).
  • Serum IGFBP-2 levels were elevated in women with early- and advanced-stage ovarian cancer compared to controls and patients with benign gynecological conditions (P = 0.05 and P < 0.01, respectively).
  • Epithelial ovarian cancers express high levels of IGFBP-2 relative to normal ovarian epithelium, and this is associated with elevated serum IGFBP-2 levels compared to both normal controls and patients with benign gynecological disease.
  • Our findings provide further support that the insulin-like growth factor pathway plays a significant role in epithelial ovarian cancer pathogenesis.
  • Further, IGFBP-2 may represent an additional serum biomarker with utility in detection and monitoring of epithelial ovarian cancer.

  • [Title] Characterization of the 3p12.3-pcen region associated with tumor suppression in a novel ovarian cancer cell line model genetically modified by chromosome 3 fragment transfer.
  • The genetic analysis of nontumorigenic radiation hybrids generated by transfer of chromosome 3 fragments into the tumorigenic OV-90 ovarian cancer cell line identified the 3p12.3-pcen region as a candidate tumor suppressor gene (TSG) locus.
  • The expression of all but one (VGLL3) of these genes was also detected in the parental OV-90 cell line.
  • Mutations were not identified in a comparative sequence analysis of the predicted protein coding regions of these candidates in OV-90 and donor normal chromosome 3 contig.
  • Interestingly, underexpression of VGLL3 and ZNF654 were observed in malignant ovarian tumor samples as compared with primary cultures of normal ovarian surface epithelial cells or benign ovarian tumors, and this occurred regardless of allelic content of 3p12.3-pcen.
  • The results taken together suggest that dysregulation of VGLL3 and/or ZNF654 expression may have affected pathways important in ovarian tumorigenesis which was offset by the transfer of chromosome 3 fragments in OV-90, a cell line hemizygous for 3p.

  • [Title] Identification of candidate biomarkers with cancer-specific glycosylation in the tissue and serum of endometrioid ovarian cancer patients by glycoproteomic analysis.
  • Epithelial ovarian cancer is diagnosed less than 25% of the time when the cancer is confined to the ovary, leading to 5-year survival rates of less than 30%.
  • Therefore, there is an urgent need for early diagnostics for ovarian cancer.
  • Our study using glycotranscriptome comparative analysis of endometrioid ovarian cancer tissue and normal ovarian tissue led to the identification of distinct differences in the transcripts of a restricted set of glycosyltransferases involved in N-linked glycosylation.
  • In this study, we have extended our observations by the use of selected lectins to perform a targeted glycoproteomic analysis of ovarian cancer and normal ovarian tissues.
  • Our results have identified several glycoproteins that display tumor-specific glycosylation changes.
  • The glycoproteins that were verified were then analyzed further using existing microarray data obtained from benign ovarian adenomas, borderline ovarian adenocarcinomas, and malignant ovarian adenocarcinomas.
  • The verified glycoproteins found to be expressed above control levels in the microarray data sets were then screened for tumor-specific glycan modifications in serum from ovarian cancer patients.
  • Results obtained from two of these glycoprotein markers, periostin and thrombospondin, have confirmed that tumor-specific glycan changes can be used to distinguish ovarian cancer patient serum from normal serum.

64. Kline RC, Bazzett-Matabele LB: Adnexal masses and malignancies of importance to the colorectal surgeon. Clin Colon Rectal Surg; 2010 Jun;23(2):63-71

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • In this article, the authors review both benign and malignant ovarian masses, as the colorectal surgeon who encounters an adnexal mass at the time of surgery should be aware of the steps necessary for surgical staging and optimal tumor resection.Ovarian tumors-most of which are benign-are divided into three major categories, in order of frequency: epithelial, germ cell, and sex cord-stromal tumors.
  • Nonneoplastic conditions of the ovary that may present as adnexal masses include the following, according to World Health Organization (WHO) classification: pregnancy luteoma, hyperplasia of ovarian stroma, hyperthecosis, massive edema, solitary follicle cysts and corpus luteal cysts, multiple follicle cysts, and endometriosis.Epithelial ovarian tumors arise from the surface epithelium and can be benign or malignant.
  • Germ cell tumors are more likely to appear in females under 20 years, accounting for 70% of ovarian tumors in this age group.
  • The more common sex cord-stromal tumors include granulosa stromal cell tumors, Sertoli-Leydig cell tumors, and gynandroblastomas.Surgical staging and optimal tumor resection are also addressed, with a focus on epithelial malignancies, as they are the most relevant to colorectal surgeons.

  • [Title] Combined staining of TAG-72, MUC1, and CA125 improves labeling sensitivity in ovarian cancer: antigens for multi-targeted antibody-guided therapy.
  • Single antigen-targeted intraperitoneal radioimmunotherapy for ovarian cancer has shown limited success.
  • Due to the heterogeneous expression of tumor antigens on cancer cells, a multi-antigen targeting approach appears logical to augment the therapeutic efficacy of antibody-guided therapy.
  • In the interest of developing this novel approach, ovarian cancer tissue microarray slides containing cancer and benign/non-neoplastic tissue samples (n=92) were processed for single-, double-, and triple-antigen labeling using antibodies for the tumor-associated antigens TAG-72, MUC1, and CA125.
  • Among all ovarian cancer types, 72%, 61%, and 50% of the samples showed immunolabeling for TAG-72, MUC1, and CA125, respectively.
  • Of the 48 epithelial ovarian cancer samples, individual anti-TAG-72, MUC1, and CA125 antibody probing showed labeling in 89.5%, 87.5%, and 73.0% of the cases, respectively.
  • However, upon combining the three antigens (triple-antigen labeling), 98% of the epithelial ovarian cancer samples were labeled and >95% of the cancer cells within each sample were labeled.
  • Therapeutic efficacy of antibody-guided therapy for ovarian cancer treatment will be enhanced by the combined targeting of TAG-72, MUC1, and CA125.

  • [Title] Changes in the expression of E-cadherin repressors, Snail, Slug, SIP1, and Twist, in the development and progression of ovarian carcinoma: the important role of Snail in ovarian tumorigenesis and progression.
  • Changes in the expression of E-cadherin have been reported to be important in the tumorigenesis and progression of epithelial ovarian carcinoma.
  • To further examine the mechanisms regulating E-cadherin expression in ovarian tumorigenesis, we investigated the immunohistochemical expression of transcriptional repressors for E-cadherin, such as Snail, Slug, SIP1, and Twist, in the ovarian surface epithelium (OSE) and 95 cases of epithelial ovarian tumors.
  • Of 95 ovarian tumors, the expression of Snail, Slug, SIP1, and Twist increased stepwise in benign, borderline, and malignant tumors.
  • The prognosis of ovarian carcinoma patients positive for Snail expression was poorer than that of negative patients.
  • Our results indicate that the expression of E-cadherin transcriptional repressors increased with malignancy in ovarian epithelial neoplasms and that the expression of E-cadherin and its negative regulators is altered during ovarian cancer development and peritoneal dissemination.

  • [Title] The Notch pathway in ovarian carcinomas and adenomas.
  • Elements of the Notch pathway regulate differentiation; we investigated the expression of such elements in epithelial ovarian tumours.
  • A total of 32 ovarian tumour samples (17 adenocarcinomas, three borderline tumours, 12 adenomas), two human ovarian cancer (A2780, OVCAR3), and one ovarian surface (IOSE 144) cell lines were analysed.
  • Quantitative PCR revealed decreased Notch 1 mRNA in ovarian adenocarcinomas compared with adenomas.
  • The expression of Notch 1-EC protein was similar in benign and malignant tumours.
  • HES1 protein was strongly expressed in 18/19 ovarian cancers and borderline tumours but not in adenomas.
  • Thus, Notch pathway elements are expressed in ovarian epithelial tumours and some of them are differentially expressed between adenomas and carcinomas.
  • The Notch pathway could be a target for the development of therapies for ovarian cancer.

  • [Title] Ber-EP4 and anti-calretinin antibodies: a useful combination for differential diagnosis of various histological types of ovarian cancer cells and mesothelial cells.
  • The differential diagnosis between reactive mesothelial cells and ovarian carcinoma cells is often difficult in cytologic specimens.
  • Immunocytochemical procedures have been utilized in assisting this differential diagnosis, with limitations.
  • Furthermore, previous studies examined only serous type but not other histological types of ovarian carcinoma cases.
  • Therefore, we evaluated the practical value of various epithelial and mesothelial markers in differential diagnosis of these two types of cells.
  • Various types of ovarian carcinoma (serous, n = 22; mucinous, n = 10; endometrioid, n = 7; clear cell, n = 10) and benign mesothelial tissues (n = 15) were studied by immunohistochemistry.
  • We then studied effective panels of antibodies by immunohistochemistry in 43 cytologic specimens of ascites or peritoneal lavage fluid consisting of 20 reactive mesothelium and 23 adenocarcinomas of the ovary.
  • In the tissue specimens, Ber-EP4, a monoclonal antibody of epithelial antigen, and a polyclonal antibody against calretinin, which is expressed in mesothelium, are used in differentiating reactive mesothelial cells from ovarian carcinoma.
  • Using multiple regression analysis, the correlation coefficient between epithelial antigen and calretinin reactivity was r = 0.938, with a significance level of p < 0.0001.
  • In conclusion, the combined immunostaining of cytologic specimens for Ber-EP4 and the anti-calretinin antibody is helpful for the differential diagnosis between mesothelial cells and not only serous type, but also mucinous, endometrioid and clear cell types of ovarian cancer cells.

  • [Title] [Expression of KiSS-1, matrix metalloproteinase-9, nuclear factor-kappaBp65 in ovarian tumour].
  • OBJECTIVE: To investigate the expression and correlation of KiSS-1, matrix metalloproteinase-9 (MMP-9) and nuclear factor (NF)-kappaBp65 proteins in primary epithelial ovarian tumors.
  • METHODS: Expression of KiSS-1, MMP-9, NF-kappaBp65 proteins in primary ovarian epithelial tumors (malignant n = 50, borderline tumor n = 20, benign adenoma n = 20, normal tissue n = 10) was evaluated by immunohistochemical staining.
  • RESULTS: Expression of metastin protein in primary epithelial ovarian cancers was significantly higher than that in ovarian benign adenoma (P < 0.05) and normal tissues (P < 0.05).
  • Expression of metastin protein in ovarian borderline tumors was significantly higher than that in normal tissues (P < 0.05).
  • Expression of metastin protein in ovarian cancer was significantly correlated with node metastasis (P < 0.05).
  • MMP-9 protein was positive in 68% (34/50) of the epithelial ovarian cancers, significantly higher than that in normal tissues (20%, 2/10; P < 0.05).
  • NF-kappaBp65 protein was positive in 72% (36/50) of the epithelial ovarian cancers, significantly higher than that in ovarian benign adenoma (30%, 6/20; P < 0.05) and normal tissues (10%, 1/10; P < 0.05).
  • The expression of MMP-9 protein in epithelial ovarian cancer was significantly correlated with FIGO stage (P < 0.05) and lymph node metastasis (P < 0.05).
  • The expression of NF-kappaBp65 protein in epithelial ovarian cancer was significantly correlated with FIGO stage (P < 0.05), differentiation grade (P < 0.05) and lymph node metastasis (P < 0.05).
  • There was obviously negative correlation between KiSS-1 and MMP-9 expression in ovarian cancer (rs = -0.547, P < 0.05), as well as between KiSS-1 and NF-kappaBp65 expression in ovarian cancer (rs = -0.414, P < 0.05), while there was obviously positive correlation between MMP-9 and NF-kappaBp65 expression in ovarian cancer (rs = 0.695, P < 0.05).
  • CONCLUSION: The results indicate that KiSS-1 plays some role in suppression of the metastasis of ovarian epithelial cancers, which may be through inhibiting the expression of MMP-9 and NF-kappaBp65.

  • [Title] [Relation between the expression of hypoxia inducible factor-1alpha and angiogenesis in ovarian cancer using tissue microarray].
  • OBJECTIVE: To study the relation between the expression of hypoxia inducible factor-1alpha (HIF-1alpha)and angiogenesis in ovarian cancer.
  • METHODS: The expressions of HIF-1alpha mRNA, vascular endothelial growth factor (VEGF), and CD(34) in 295 patients with epithelial ovarian tumors were analyzed by tissue microarray technology, in situ hybridization and immunohistochemistry, and compared with those of 13 normal ovarian tissue samples.
  • RESULTS: The expressions of HIF-1alpha mRNA were observed in 0, 13.2%, 42.1% and 81.9% of normal ovarian tissue, benign, borderline and malignant ovarian tumors respectively.
  • Expression rates of HIF-1alpha mRNA in borderline and invasive tumors were significantly higher than those in normal ovarian tissues and benign tumors (P < 0.01).
  • Close positive relation was observed between the expression of HIF-1alpha mRNA and tumor histological grade (r = 0.246, P < 0.01).
  • CONCLUSION: HIF-1alpha may play a role in angiogenesis of ovarian carcinoma, and may promote the development of the carcinoma.

  • [Title] Ovarian involvement by metastatic colorectal adenocarcinoma: still a diagnostic challenge.
  • Ovarian involvement by metastatic colorectal adenocarcinoma, although not an uncommon occurrence, remains a diagnostic challenge.
  • The gross and histologic features of such metastases overlap those of primary ovarian epithelial neoplasms such as endometrioid or mucinous adenocarcinoma.
  • The clinical and pathologic features of 86 cases of metastatic colorectal adenocarcinoma involving the ovary were reviewed.
  • In 23 cases, an ovarian mass was the first manifestation of the disease.
  • Ovarian involvement was bilateral in 49 cases and unilateral in 33 (including 20 cases in which the only involved ovary measured at least 10 cm in greatest dimension).
  • Many involved ovaries featured smooth capsules without gross evidence of surface involvement by tumor.
  • In 23 cases, foci with a benign or low malignant potential appearance were seen.
  • In 9 of the cases, an ovarian primary was diagnosed or favored initially, and 5 of these cases were initially treated as ovarian primaries.
  • Metastatic colorectal adenocarcinoma should be considered in the differential diagnosis of an ovarian mass, even if the mass is large and unilateral or in a young patient, to secure proper treatment of these patients.

  • PURPOSE OF REVIEW: Borderline ovarian tumors (BOTs) are a distinct diagnostic category of epithelial ovarian tumors, distinguished from both benign and invasive epithelial ovarian tumors.
  • As potential alternative, experiences on ovarian tissue cryopreservation have been reported.
  • If fertility-sparing surgery is technically not feasible owing to extensive tumor involvement of both ovaries, recent artificial reproductive technologies can be considered, including embryo, oocyte, and ovarian tissue freezing; use of donor oocytes; and surrogacy, but more experience with these options is required.

74. McCluggage WG: Mullerian adenosarcoma of the female genital tract. Adv Anat Pathol; 2010 Mar;17(2):122-9
MedlinePlus Health Information. consumer health - Uterine Cancer.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Mullerian adenosarcoma is an uncommon, but not rare, mixed tumor containing a neoplastic but benign or mildly atypical epithelial element and a sarcomatous, usually low-grade, stromal component.
  • The most common site is the uterine corpus but adenosarcoma also occurs in the cervix and ovary and more rarely in the vagina, fallopian tube, arising from peritoneal surfaces, or outside the female genital tract, for example in the intestine.
  • Characteristic histologic features include a low power "phyllodes-like" architecture with leaf-like projections lined by a variety of benign Mullerian type epithelia, sometimes with squamous metaplasia.
  • Intraglandular stromal protrusions are a characteristic feature.
  • The stroma may be uniformly cellular but there is typically increased cellularity around the epithelial elements, resulting in the formation of a cambium layer.
  • Using the World Health Organization definition, stromal mitotic activity of 2 or more per 10 high-power fields is required for a diagnosis of adenosarcoma but in practice the diagnosis is made with stromal mitotic activity less than this if the characteristic architecture and cambium layer is present.
  • The stromal component is usually morphologically "low-grade" and of endometrial stromal or fibroblastic type (hormone receptor and CD10 positive).
  • Additional features sometimes present include heterologous stromal elements or sex cord-like differentiation.
  • The 2 most important adverse prognostic factors, which sometimes coexist, are deep myometrial invasion and sarcomatous overgrowth; the latter is usually associated with morphologically "high-grade" stromal elements with loss of expression of hormone receptors and CD10.
  • Adenosarcoma may be confused with a variety of lesions and one of the main differential diagnoses is adenofibroma in which the stromal component is, by definition, morphologically benign.
  • Ovarian adenosarcomas are much more likely to exhibit malignant behavior than their uterine counterparts, probably due to the lack of an anatomic barrier to peritoneal dissemination.

  • The expression of both mbl2 and masp-2 genes were investigated in ovarian tissue sections.
  • Additionally, samples from patients with other malignant and benign tumours of the reproductive tract were tested.
  • MBL-specific mRNA expression was detected in several normal and malignant ovarian tissues, as well as in ovarian epithelial cell lines.
  • Intracellular staining with MBL-specific antibodies demonstrated the presence of MBL in ovarian cell lines, and in normal as well as malignant ovarian tissue sections.
  • In contrast, MASP-2-specific mRNA expression was detected only in the ovary tissues of patients with malignant disease.
  • MBL was detected in ascites and in the fluid of benign ovarian cysts.
  • However, it cannot be excluded that mbl-2 mutant alleles may be in linkage disequilibrium with an unidentified tumour susceptibility gene(s).

  • [Title] Type 2 11beta-hydroxysteroid dehydrogenase activity in human ovarian cancer.
  • In the ovary cortisol-cortisone inter-conversion is catalyzed by the enzyme 11beta-hydroxysteroid dehydrogenase (11beta-HSD).
  • Its role in carcinomas of human ovary is unknown.
  • The majority of ovarian cancers are derived from ovarian surface epithelium and the inflammation caused by successive ovulation seems to a play a role in the development of cancer.
  • Cortisol is known to act as anti-inflammatory agent and its metabolism by type 1 and type 11beta-HSD may control the inflammatory action by cortisol in ovary.
  • We undertook this study to investigate type 2 11beta-HSD activity which functions exclusively oxidative direction, in normal ovarian tissue compared to ovarian epithelial cancer.
  • Ovarian tissue was obtained from patients undergoing hysterectomy for both benign and malignant disease.
  • Mean type 2 enzyme activity was 0.87 +/- 1.65 pmol/min g tissue in normal ovarian tissue versus a mean enzyme activity of 2.96 +/- 1.37 pmol/mim g tissue in from cancer specimens.
  • Type 2 1beta-HSD activity in ovarian cancer specimens was significantly higher than enzyme activity measured in normal post-menopausal ovarian tissue.
  • Decreased cortisol levels due type 2 1beta-HSD activity may play a role neoplastic transformation as well as tumor proliferation in ovarian cancer by eliminating anti-inflammatory action of cortisol.

  • [Title] The influence of aquaporin-1 and microvessel density on ovarian carcinogenesis and ascites formation.
  • This study aimed at investigating aquaporin-1 (AQP1) distribution and expression in primary ovarian epithelial tumors, correlating with clinicopathologic variables and intratumoral microvessel density (IMD).
  • The AQP1 expression and IMD in 105 cases with primary epithelial ovarian tumors were measured by semiquantitative immunohistochemical technique.
  • AQP1 was located mainly in microvessels and small vessels but seldom in tumor cells.
  • Expression of AQP1 and IMD in ovarian malignant tumors was significantly higher than that in borderline tumors (P= 0.000, P= 0.001, respectively), and that in borderline tumors was higher than in benign tumors (P= 0.008, P= 0.028, respectively).
  • These data implicate that high AQP1 expression may play an important role in the ovarian carcinogenesis, progression, and ascites formation.
  • Further studies into the mechanism of AQP1 regulation and the relationship between AQP1 expression and tumor angiogenesis may lead to novel therapies for ovarian carcinoma.

  • [Title] Formation of E-cadherin-mediated cell-cell adhesion activates AKT and mitogen activated protein kinase via phosphatidylinositol 3 kinase and ligand-independent activation of epidermal growth factor receptor in ovarian cancer cells.
  • E-cadherin is a well characterized adhesion molecule that plays a major role in epithelial cell adhesion.
  • Based on findings that expression of E-cadherin is frequently lost in human epithelial cancers, it has been implicated as a tumor suppressor in carcinogenesis of most human epithelial cancers.
  • However, in ovarian cancer development, our data from the current study showed that E-cadherin expression is uniquely elevated in 86.5% of benign, borderline, and malignant ovarian carcinomas irrespective of the degree of differentiation, whereas normal ovarian samples do not express E-cadherin.
  • Thus, we hypothesize that E-cadherin may play a distinct role in the development of ovarian epithelial cancers.
  • Using an E-cadherin-expressing ovarian cancer cell line OVCAR-3, we have demonstrated for the first time that the establishment of E-cadherin mediated cell-cell adhesions leads to the activation of Akt and MAPK.
  • We therefore suggest that the concurrent formation of E-cadherin adhesion and activation of downstream proliferation signals may enhance the proliferation and survival of ovarian cancer cells.
  • Our data partly explain why E-cadherin is always expressed during ovarian tumor development and progression.

  • [Title] Properties of L-type amino acid transporter 1 in epidermal ovarian cancer.
  • HYPOTHESIS: To investigate the expression and the functional properties of L-type amino acid transporter 1 (LAT1) in human epithelial ovarian cancer to provide a basis for potential new therapies to control the growth and the metastasis of ovarian cancer.
  • The expression of LAT1 in 53 cases of ovarian cancers was determined by Western blot and immunohistochemical staining, and results were compared with those of normal ovarian tissues (5 cases) and benign ovarian tumors (5 cases).
  • Furthermore, we examined the effect of 2-aminobicyclo-(2,2,1)-heptane-2-carboxylic acid (BCH), the classic inhibitor of system L on the survival, the migration, and the uptake of l-leucine by human epithelial ovarian cancer cell line (OVCAR-3).
  • RESULTS: The LAT1 was significantly up-regulated in various human epithelial ovarian cancers that was localized predominantly on their plasma membrane and in the plasma membrane of the ovarian cancer cell line in conjunction with 4F2hc via disulfide bonds.
  • CONCLUSIONS: The LAT1 plays significant roles in nutrition, proliferation, and migration of ovarian cancer.
  • Then, LAT1 inhibition would be useful for anticancer therapy in suppressing tumor growth without affecting normal tissues.

  • [Title] Expression of soluble interleukin-6 receptor in malignant ovarian tissue.
  • OBJECTIVE: The objective of the study was to investigate interleukin-6 receptor (IL6R) isoforms and sheddases in the ovarian tumor microenvironment.
  • STUDY DESIGN: Expression of IL6R and sheddases was measured in tissue samples of papillary serous ovarian carcinomas and benign ovaries by real-time polymerase chain reaction and immunohistochemistry.
  • Murine xenograft samples were tested by enzyme-linked immunosorbent assay to discriminate and evaluate tumor and host contributions of IL6R.
  • RESULTS: IL6R expression was increased in malignant ovarian tumors and localized to epithelial cells.
  • An in vivo xenograft model showed that host IL6R expression is also increased and regulated by tumor-associated inflammation.
  • CONCLUSION: IL6R is overexpressed in epithelial ovarian malignancies because of increases in a soluble IL6R variant, in the sheddases for full-length IL6R and host IL6R expression.

  • Germline mutations in the hereditary breast/ovary carcinoma genes BRCA1 or BRCA2 confer increased lifetime risk for ovarian, fallopian tube, and primary peritoneal carcinoma.
  • Transitional cell metaplasia is a benign epithelial alteration that is a common finding in the serosa of the tube but is underrecognized in the tubal fimbriae, where it may mimic tubal intraepithelial carcinoma.
  • RRSO specimens from an additional 30 women at increased risk for ovarian cancer based on strong family history were also studied, along with RRSO from 1 patient with Lynch syndrome, and 1 patient with PTEN mutation.
  • Median tumor size was 2.7 mm (range: 1 to 11 mm).
  • No particular clinical variables (BRCA 1 vs. BRCA 2 mutation, parity, personal history of breast cancer, prior abdomino-pelvic surgery, or intraoperative findings) or benign pathologic alterations in the RRSO specimens were associated with the presence of transitional cell metaplasia of the fimbriae.
  • This study demonstrates that transitional cell metaplasia of the fimbriae is a common benign finding in RRSO specimens that should not be confused with the much less common finding of tubal intraepithelial carcinoma.

  • [Title] Peritoneal and subperitoneal stroma may facilitate regional spread of ovarian cancer.
  • PURPOSE: Epithelial ovarian cancer (EOC) is characterized by early peritoneal involvement ultimately contributing to morbidity and mortality.
  • To study the role of the peritoneum in fostering tumor invasion, we analyzed differences between the transcriptional repertoires of peritoneal tissue lacking detectable cancer in patients with EOC versus benign gynecologic disease.
  • EXPERIMENTAL DESIGN: Specimens were collected at laparotomy from patients with benign disease (b) or malignant (m) ovarian pathology and comprised primary ovarian tumors, paired bilateral specimens from adjacent peritoneum and attached stroma (PE), subjacent stroma (ST), peritoneal washes, ascites, and peripheral blood mononuclear cells.
  • RESULTS: Principal component analysis and unsupervised clustering did not segregate specimens from patients with benign or malignant pathology.
  • Class comparison identified differences between benign and malignant PE and ST specimens deemed significant by permutation test (P = 0.027 and 0.012, respectively).

  • [Title] Up-regulation of CXC chemokines and their receptors: implications for proinflammatory microenvironments of ovarian carcinomas and endometriosis.
  • Molecular abnormalities in the epithelial cells of endometriosis and their relevance to carcinogenesis of the ovary have been well studied.
  • On the other hand, the differences of proinflammatory microenvironments between endometriosis and ovarian carcinomas have not been well documented yet.
  • In this study, the expression patterns of CXC chemokines (IL-8, ENA-78, GRO-alpha, I-TAC, Mig, and SDF-1) and their receptors (CXCR2, CXCR3, and CXCR4) were compared among 12 ovarian carcinomas, 8 endometriosis, and 6 normal ovaries using quantitative reverse transcriptase polymerase chain reaction and immunohistochemistry.
  • The CXCR3-mediated signaling in ovarian carcinoma cells in vitro was also investigated.
  • In carcinoma-endometriosis coexisting cases, CXCR3-positive lymphocytes in benign lesions decreased in proportion as CXCR3-positive tumor cells replaced the tissues.
  • CXCR3 was also detected in ovarian carcinoma cell lines in vitro.
  • The results indicated that CXC chemokines might contribute to the progression of ovarian carcinomas and endometriosis in different manners.
  • Aberrant expression of IFN-gamma-inducible chemokines and CXCR3 in carcinoma cells in association with reduced CXCR3-positive immune cells raised the possibility that IFN-gamma-inducible chemokines might not exert effective antitumor immune responses but that they might work in favor of tumor progression.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Risk-reducing salpingo-oophorectomy (RRSO) significantly lowers the incidence of ovarian, tubal, peritoneal, and breast cancer in women who carry BRCA1 or BRCA2 germline mutations.
  • Recommended protocols to maximize tumor detection emphasize the role of thinly slicing the tubes and ovaries and embedding the entire specimen for microscopic examination.
  • Clinically occult carcinoma ranging in size from 1 to 13 mm was initially detected in 11 of 102 women (5 in tubal fimbriae only, 1 in tubal isthmus only, 2 in fimbriae and ovary, and 3 in ovary only).
  • No tubal carcinoma was identified in the level sections of any case originally classified as benign.
  • Clinical follow-up among women with benign RRSO findings revealed that 2 women subsequently developed peritoneal carcinomatosis at 22 and 62 months postoperatively.
  • Retrospective exhaustive multistep level sectioning of all remaining tubal and ovarian blocks from both these women confirmed the original benign diagnosis in 1 woman but in the other woman, the deepest levels of 1 ovarian block revealed a single 1-mm nodule of cancer at the base of an ovarian surface epithelial invagination.
  • This specimen was one of the first RRSO cases in our experience and on review of the original report, this ovary was not dissected into multiple slices along its short axis but was only bivalved along its long axis.

  • [Title] Stromal osseous metaplasia in a low-grade ovarian adenocarcinoma.
  • BACKGROUND: Stromal osseous metaplasia is a rare and curious finding in tumors of the ovary.
  • CASE REPORT: The patient, a 66-year-old P3 G3 white female, had a past history of stage 1c left ovarian, well-differentiated endometrioid adenocarcinoma removed in 1981.
  • The tumor recurred 21 years later with prominent stromal osseous metaplasia that had not been present in the primary.
  • DISCUSSION: The pathogenesis of osseous metaplasia in epithelial tumors of the ovary is unclear; however, it is probable that a metaplastic process involving multipotential stromal stem cells results in bone formation.
  • CONCLUSION: Benign osseous metaplasia in ovarian tumors is rare and its histogenesis remains unclear.

  • [Title] Ovarian nonsmall cell neuroendocrine carcinoma: a clinicopathologic and immunohistochemical study of 11 cases.
  • Nonsmall cell neuroendocrine carcinoma (NSCNEC) of the ovary is a rare and aggressive tumor commonly associated with other surface epithelial and germ cell neoplasms.
  • In 8 cases, NSCNEC was associated with other epithelial neoplasms, including mucinous neoplasms of low malignant potential, mucinous carcinoma, endometrioid carcinoma, mixed endometrioid and mucinous carcinoma, and a high-grade carcinoma, not otherwise specified.
  • In 2 cases, the tumor was associated with a mature cystic teratoma; one of them also containing an invasive moderately differentiated adenocarcinoma.
  • A single case was associated with a benign ovarian cyst.
  • The latter case had a dermoid cyst in the contralateral ovary.
  • NSCNEC represented anywhere from 10% to 90% of the ovarian tumor.
  • In summary, ovarian NSCNEC is an aggressive tumor with a tendency to present at advanced stage and cause death within a mean of 17 months after diagnosis; however, some patients, particularly those with stage I disease and/or those who have received platinum-based therapy, may have a more favorable prognosis.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • BACKGROUND: Recent data provide significant evidence to support the hypothesis that there are sub-populations of cells within solid tumors that have an increased tumor initiating potential relative to the total tumor population.
  • CD133, a cell surface marker expressed on primitive cells of neural, hematopoietic, endothelial and epithelial lineages has been identified as a marker for tumor initiating cells in solid tumors of the brain, colon, pancreas, ovary and endometrium.
  • In addition, we confirmed the tumor initiating potential of CD133+ and CD133- cell fractions in NOD/SCID mice.
  • Interestingly, the percentage of CD133+ cells in human endometrial tumor xenografts, as evidenced by immunofluorescence, increased with serial transplantation although this trend was not consistently detected by flow cytometry.
  • To support this finding, we demonstrated that regions of the CD133 promoter were hypomethylated in malignant endometrial tissue relative to benign control endometrial tissue.
  • Lastly, we determined that methylation of the CD133 promoter decreases over serial transplantation of an endometrial tumor xenograft.

  • [Title] Transient bilateral ovarian enlargement associated with large retroperitoneal lymphoma.
  • Bilateral ovarian enlargement may reflect benign or malignant processes of the ovary.
  • Benign causes of ovarian enlargement include luteomas, tumors such as mature cystic teratomas, fibrothecomas, cystadenomas and rare conditions including capillary hemangioma and massive edema of the ovaries.
  • Ovarian malignancies include epithelial, stromal and germ-cell tumors.
  • We present an unusual case in which a patient presenting with weakness and mild lower abdominal and pelvic pain was noted at sonography to have bilaterally enlarged ovaries with features similar to those of massive ovarian edema as described previously, which has been associated with venous and lymphatic obstruction.
  • Subsequent computerized tomography (CT) imaging depicted a large retroperitoneal tumor, CT-guided biopsy of which revealed diffuse large B cell lymphoma.
  • The patient responded well to chemotherapy with significant shrinkage of the tumor, and reappearance of normal findings on ovarian sonography.
  • This case demonstrates that bilaterally enlarged ovaries may be the first clinical evidence of a large retroperitoneal tumor and that in such cases CT imaging may be warranted.

  • Epithelial ovarian cancer derived from the human ovarian surface epithelium (HOSE) is the leading cause of death from gynecologic malignancies among American women.
  • In this study, we showed overexpression of CYP1A1 mRNA, but not CYP1B1 transcripts, in ovarian cancer cell lines when compared with primary cultures or immortalized HOSE cell lines.
  • CYP1A1v is overexpressed in ovarian cancer cell lines and exhibits a unique subcellular distribution restricted to the nucleus and mitochondria, contrary to the endoplasmic reticulum localization of the wild-type enzyme.
  • In concordance, total CYP1A1 activity, as measured by the ethoxyresorufin O-deethylase assay, was detected in mitochondrial, nuclear, and microsomal fractions of ovarian cancer cells but was notably absent in all subcellular fractions of HOSE cells.
  • Immunocytochemistry studies in 30 clinical specimens revealed overexpression of CYP1A1 in various types of ovarian cancers compared with benign epithelia and frequent localization of the enzyme to cancer cell nuclei.
  • Collectively, these data provided the first evidence that CYP1A1 overexpression and alternative splicing could contribute to ovarian cancer initiation and progression.

  • [Title] Loss of Gelsolin expression in human ovarian carcinomas.
  • In the present study, we analysed the expression of gelsolin in 241 matched cDNA pairs from human normal and tumour tissues using a Cancer Profiling Array.
  • We found a decreased expression of gelsolin in cancer tissue from female reproductive organs, including the ovary.
  • On a protein level, we examined the expression of gelsolin in human ovarian cancer cell lines and in a set of 110 cases of human benign and malignant ovarian tumours.
  • Low levels of gelsolin protein were observed in four of six ovarian carcinoma cell lines, in contrast to its expression in normal ovarian surface epithelial cells.
  • In addition, we found a reduced expression of gelsolin in borderline tumours and ovarian carcinomas compared with the epithelium of normal ovaries and benign adenomas.
  • In addition, we investigated the growth regulatory function of gelsolin in human ovarian cancer cell lines using cDNA transfections.
  • Re-expression of gelsolin in OAW42 and ES-2 cells resulted in a suppression of tumour cell survival in vitro.
  • To explore the mechanism responsible for the downregulation of gelsolin expression in ovarian carcinoma cells, we treated cells with inhibitors of DNA methylation and histone deacetylation.
  • We observed an upregulation of gelsolin in ovarian cancer cells after treatment with both types of inhibitor.
  • Our results suggest that gelsolin might be involved in the growth regulation of human ovarian cancer.

  • [Title] Can we preoperatively risk stratify ovarian masses for malignancy?
  • PURPOSE: Given a 10% malignancy rate in pediatric ovarian masses, what preoperative factors are helpful in distinguishing those at higher risk to risk stratify accordingly?
  • METHODS: After institutional review board approval (IRB#022008-095), a 15(1/2)-year retrospective review of operative ovarian cases was performed.
  • RESULTS: A total of 424 patients were identified, with a mean age 12.5 years (range, 1 day to 19 years), without an age disparity between benign (12.54 years, 89%) and malignant (11.8 years, 11%) cases.
  • Imaging of benign neoplasms had a mean size of 8 cm (range, 0.9-36 cm) compared with malignancies at 17.3 cm (6.2-50 cm, P < .001).
  • An ovarian mass size of 8 cm or longer on preoperative imaging had an OR of 19.0 for malignancy (95% CI, 4.42-81.69).
  • The malignancies (n = 46) included germ cell (50%, n = 23), stromal (28%, n = 13), epithelial (17%, n = 8), and other (4%, n = 2).
  • Tumor markers obtained in 71% of malignancies were elevated in only 54%, whereas 6.5% of those sent in benign cases were similarly elevated.
  • CONCLUSION: This reported series of pediatric ovarian masses demonstrates that preoperative indicators that best predict an ovarian malignancy are a complaint of a mass or precocious puberty, a mass exceeding 8 cm or a mass with solid imaging characteristics.
  • Tumor markers, positive or negative, were not conclusive in all cases but useful for postoperative surveillance.

  • The pathologic changes of AEM including its glandular epithelium, stroma, background and the conditions coexisting with tumor were observed.
  • Of 172 AEM foci of 163 patients, 168 were in the ovary, and the other 4 were in the fallopian tube, cervix and uterine serosa respectively.
  • The rate of ovarian AEM was 6.81% of endometriosis.
  • AEM associated with tumour was found in 26 cases (15.95%) and among 27 of ovarian AEM, 15 were malignant, 9 borderline and 3 benign.
  • The AEM epithelia were mainly arranged in the form of surface epithelium.
  • They present with characteristic features of moderate to marked pleomorphism, epithelial tufting and bud structures by microscopy.
  • The transformation from AEM to tumor was found in most of the malignant tumors (14/15, 93%).
  • CONCLUSIONS: AEM lesions hold some features of both EM and tumor, which may have a relatively higher potential for tumorigenesis and canceration.
  • The process of damage and repair in EM foci during a long course may play a role in the development of EM into AEM and finally into tumor.

  • To evaluate the expression of p21 in tissues prone or resistant to tumorigenesis as a function of gamma-irradiation, and to determine whether phenotypic loss of p21 heterozygosity occurs during tumor progression in p21(+/-) mice, tissues and tumors from gamma-irradiated mice were evaluated immunohistochemically.
  • Benign tumors were more often p21-positive and comprised of larger subsets of nuclear p21-positive cells than were malignant tumors of the same histopathological type, while metastatic cancers were nuclear p21-negative (p=0.0003).
  • Mesenchymal tumors, though rare, were more likely metastatic than were epithelial tumors (p=0.0004), and these were invariably nuclear p21-negative.
  • Prepubescent epithelial tissues from which most tumors later originated in mice with reduced p21 gene dosage (i.e., harderian gland, ovary, small intestine, and lung) were p21 expressive within 4 h of gamma-irradiation (p=0.0625), so that p21/Ki67 ratios increased post-gamma-irradiation (p=0.03).

  • [Title] ERK activation and nuclear signaling induced by the loss of cell/matrix adhesion stimulates anchorage-independent growth of ovarian cancer cells.
  • Ovarian cancer metastasis involves the sloughing of epithelial cells from the ovary into the peritoneal cavity, where the cells can survive and proliferate in peritoneal ascites under anchorage-independent conditions.
  • For normal epithelial cells and fibroblasts, cell adhesion to the extracellular matrix is required to prevent apoptosis and for proper activation and nuclear signaling of the ERK MAP kinase.
  • In this report, we elucidate a novel means of ERK regulation by cellular adhesion in ovarian cancer cells.
  • We demonstrate that ERK and its activator MEK are robustly stimulated after cell detachment from a substratum in several ovarian cancer cell lines, but not a benign ovarian cell line, independent of serum and FAK or PAK activity.
  • Re-attachment of suspended ovarian cells to fibronectin restored basal levels of MEK and ERK activity.
  • These data demonstrate a unique regulation of ERK by cellular adhesion and suggest a mechanism by which ERK may regulate anchorage-independent growth of metastatic ovarian cancer cells.

  • In this study, we addressed the expression of TREK-1 in prostatic tissues and cell lines, and we have found that this potassium channel is highly expressed in prostate cancer but is not expressed in normal prostate nor in benign prostatic hyperplasia.
  • In vitro studies showed that TREK-1 is highly expressed in PC3 and LNCaP prostate cancer cell lines but is not detectable in normal prostate epithelial cells (NPE).
  • In this report, we show that overexpression of TREK-1 in NPE and Chinese hamster ovary (CHO) cells leads to a significant increase in proliferation.

  • [Title] [Expression of mesothelin mRNA and protein in ovarian carcinomas].
  • OBJECTIVE: To investigate the expression of mesothelin (MESO) mRNA and protein and its significance in ovarian carcinomas.
  • METHODS: Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) and immunohistochemistry were used to detect the expression level of MESO mRNA and protein, respectively, in 124 samples of ovarian tumor and normal tissues, including 84 epithelial ovarian carcinomas, 12 borderline ovarian tumors, 16 benign ovarian tumors and 12 normal ovarian tissues.
  • RESULTS: The expression of MESO mRNA and protein in epithelial ovarian carcinomas (1.4005 +/- 0.4646, 2.7857 +/- 2.2712) and borderline ovarian tumors (1.0650 +/- 0.3100, 2.9167 +/- 2.391) were significantly higher than that in benign ovarian tumors (0.6463 +/- 0.2419, 1.2500 +/- 1.6125) and normal ovarian tissues (0.6439 +/- 0.2729, 0.9167 +/- 1.2401) (P < 0.05), and also significantly higher in serous cystadenocarcinoma (1.5255 +/- 0.4151, 3.3036 +/- 2.6141) and endometrioid carcinoma (1.5250 +/- 0.5419, 3.0000 +/- 2.3094) than that in mucinous cystadenocarcinoma (1.0675 +/- 0.3149, 1.0556 +/- 1.9242) (P < 0.05).
  • CONCLUSION: The results of this study demonstrated that the expression of MESO mRNA and protein is increased in ovarian carcinomas and borderline ovarian tumors, and MESO may play a role in the adhesion and dissemination of ovarian carcinomas.

  • [Title] Expression of octamer-4 in serous and mucinous ovarian carcinoma.
  • AIMS: To assess the expression of Oct4 in epithelial ovarian tumours.
  • METHODS: Expression of Oct4 was evaluated by immunohistochemistry in 460 cases of various epithelial ovarian lesions as well as 35 cases of normal fallopian tube epithelium.
  • RESULTS: Oct4 expression was significantly increased from normal epithelium (both ovarian epithelium and fallopian tube epithelium) to benign and borderline cystadenoma to carcinoma in the serous lesion subgroup.
  • CONCLUSION: Results suggest that Oct4 expression may contribute to the initiation, promotion and progression of serous ovarian carcinoma; it might be a useful biomarker for the diagnosis and outcome prediction of serous ovarian carcinoma.

  • [Title] [Management of ovarian cysts].
  • Ovarian cysts occur frequently in women of reproductive age.
  • The most common are serous and mucinous cystadenomas which arise from the epithelial wall of the ovary, endometriomas which arise in the setting of pelvic endometriosis, and dermoid cysts which arise from the germinal cells of the ovary.
  • Pelvic laparoscopy is the surgical approach of choice for the treatment of non-functional benign ovarian cysts.
  • Conservative treatment to shell out the cyst and preserve functional ovarian tissue should be reserved for women desirous of future pregnancies.
  • The risk of ovarian cancer remains a major preoccupation of the surgeon.
  • This article describes the diagnostic techniques which allow a laparoscopic approach to presumably benign cysts and discusses surgical techniques specifically adapted to their different histologic nature of ovarian cysts.

  • [Title] Premenarchal ovarian torsion and elevated CA-125.
  • BACKGROUND: Ovarian tumors are the most common gynecologic malignancy occurring in childhood, with germ cell tumors being most frequent.
  • This contrasts with adults where epithelial tumors account for most ovarian neoplasms.
  • Tumor markers are an integral part of the work-up and may guide management.
  • Other tumor markers were normal.
  • Laparoscopy revealed an enlarged, adherent ovary.
  • A minilaparotomy revealed an ovary filled with necrotic material.
  • This necrotic material was excised and the ovary was spared.
  • SUMMARY AND CONCLUSIONS: This case demonstrates for the first time the association of an elevated CA-125 and ovarian torsion in a pediatric patient.
  • This benign finding allowed attempting a conservative ovary-sparing approach during the surgery even in the presence of a highly elevated CA-125.
  • However, in general, for children CA-125 is of limited utility, as it will not affect the indication for surgical exploration of persistent masses and elevations in CA-125 may discourage ovarian conservation.
