  • [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.

  • [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.

  • [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.

  • [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] 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] [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).
  • CONCLUSIONS:. (1) The expression of GLUT1 may be closely related to malignant transformation of ovarian epithelial tumors.
  • Both of them play important roles in the carcinogenesis and progression of ovarian epithelial carcinoma.

  • Using comparative genomic hybridization, we compared cytogenetic changes in borderline ovarian tumors and stage I invasive tumors.
  • In conclusion, we found four distinct cytogenetic alterations that might be early events in serous ovarian tumors, and that might also characterize a subgroup of borderline ovarian tumors that may have the potential to progress and develop malignancy.

  • [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] 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.

  • 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.

  • [Title] [Expression of phosphorylated protein kinase B and PTEN protein in ovarian epithelial cancer].
  • 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.

  • [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.

  • [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.

  • [Title] Immunohistochemical detection of glucose transporter GLUT1 in benign and malignant fallopian tube epithelia, with comparison to ovarian carcinomas.
  • CONTEXT: Enhanced expression of GLUT1, a facilitative glucose transporter found on red blood cells, blood-brain barrier, and perineurium, has been described in a large spectrum of epithelial malignancies.
  • OBJECTIVE: We present an immunohistochemical survey of GLUT1 expression in benign and malignant fallopian tube epithelia, and compare serous carcinomas of the fallopian tube and ovary.
  • DESIGN: One hundred two routinely fixed and processed archival specimens (36 benign fallopian tubes, 29 primary tubal adenocarcinomas, and 37 primary ovarian adenocarcinomas) were immunostained with rabbit anti-GLUT1 and developed with streptavidin-biotin/diaminobenzidine.
  • RESULTS: Benign tubes (n = 36) were either negatively stained (58.3%) or displayed rare weak staining (0.5+ to 1+, rarely 2+; 41.7%); of the latter, 4 specimens showed chronic salpingitis, and 6 showed hyperplasia (epithelial tufting and stratification).
  • Nineteen tubal carcinoma sections showed residual benign epithelium, which was consistently nonstaining.
  • Very frequently, GLUT1 staining intensified in cells furthest from stroma/ stromal capillaries and/or bordering necrotic zones.
  • On average, GLUT1 staining in primary fallopian tube cancers was less extensive than in primary ovarian adenocarcinomas.
  • CONCLUSIONS: GLUT1 immunostaining of fallopian tube adenocarcinomas was substantially stronger and more extensive than staining of benign tubal epithelium, consistent with previously described findings in carcinomas versus benign tissues from many primary sites.
  • The frequent localization of GLUT1 positivity to regions most distal from stroma/stromal capillaries is consistent with known activation of GLUT1 expression by hypoxia-sensing cellular pathways and may constitute a survival advantage under hypoxic conditions present in malignancy.
  • The difference in extent of GLUT1 staining between primary tubal and primary ovarian serous adenocarcinomas is discussed.

  • 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.

  • 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.

  • [Title] Ovarian epithelial tumors of low malignant potential: a case series of 5 adolescent patients.
  • Epithelial ovarian neoplasms are uncommon in pediatric and adolescent patients, accounting for approximately 20% to 30% of ovarian tumors in adolescent females and women younger than 25.
  • Tumors of low malignant potential (LMP) account for a significant proportion of epithelial neoplasms in this patient population.
  • This case series describes 5 adolescent patients, with a mean age of 14.4 +/- 2.4 years, diagnosed with ovarian tumors of LMP at one institution.
  • Between November 2001 and January 2006, 5 patients were diagnosed with ovarian tumors of LMP of 126 patients who had surgery for adnexal masses.
  • Two patients underwent ovarian cystectomy, and 3 had at least a unilateral salpingo-oophorectomy.
  • Three patients developed recurrent ovarian masses on follow-up.
  • Two had recurrent LMP tumors (one bilateral) and one was a benign mucinous cystadenoma.
  • This case series of 5 adolescent patients with ovarian tumors of LMP highlights the importance of considering epithelial neoplasms in any pediatric or adolescent patient with a pelvic mass and supports conservative management, with staging and fertility-sparing surgery; however, appropriate follow-up is essential, as evidenced by 3 of 5 patients exhibiting recurrent ovarian masses.

  • [Title] Differentially androgen-modulated genes in ovarian epithelial cells from BRCA mutation carriers and control patients predict ovarian cancer survival and disease progression.
  • Epidemiological studies have implicated androgens in the etiology and progression of epithelial ovarian cancer.
  • We previously reported that some androgen responses were dysregulated in malignant ovarian epithelial cells relative to control, non-malignant ovarian surface epithelial (OSE) cells.
  • Moreover, dysregulated androgen responses were observed in OSE cells derived from patients with germline BRCA-1 or -2 mutations (OSEb), which account for the majority of familial ovarian cancer predisposition, and such altered responses may be involved in ovarian carcinogenesis or progression.
  • In the present study, gene expression profiling using cDNA microarrays identified 17 genes differentially expressed in response to continuous androgen exposure in OSEb cells and ovarian cancer cells as compared to OSE cells derived from control patients.
  • Basic leucine zipper transcription factor 2 (BACH2) and acetylcholinesterase (ACHE), which were upregulated by androgen in OSEb cells relative to OSE cells, were further investigated using an ovarian cancer tissue microarray from a separate set of 149 clinical samples.
  • Both cytoplasmic ACHE and BACH2 immunostaining were significantly increased in ovarian cancer relative to benign cases.
  • The finding that products of genes differentially responsive to androgen in OSEb cells may predict survival and disease progression supports a role for altered androgen effects in ovarian cancer.
  • In addition to BACH2 and ACHE, this study highlights a set of potentially functionally related genes for further investigation in ovarian cancer.

  • [Title] Ovarian epithelial cancer: a role for PGE2-synthesis and signalling in malignant transformation and progression.
  • There are epidemiological data from subjects using NSAIDs, and experimental evidence supporting the hypothesis of prostaglandins (PGs) as regulators of tumourigenesis in the ovary.
  • One of the end products of PG-synthesis, PGE2, regulates several key-processes, which are characteristic for tumour growth, e.g. angiogenesis, proliferation and apoptosisis.
  • The present study investigated the pathway for PGE2-synthesis and signalling in ovarian tumourigenesis by analysing specimen from normal ovaries (n = 18), benign (B) (n = 8), borderline type (BL) (n = 6) and malignant tumours (AC) (n = 22).
  • RESULTS: The results are in line with earlier studies demonstrating an increase of COX-2 in AC compared to the normal ovary, B and BL tumours.
  • IHC revealed staining of the tumour cells, but also increase of COX-1, COX-2, mPGES-1 and EP1-2 in the stromal compartment of AC (grades: moderately-, poorly- and undifferentiated).
  • This observation suggests interactions between tumour cells and stromal cells (fibroblasts, immune cells), e.g. paracrine signalling mediated by growth factors, cytokines and possibly PGs.
  • CONCLUSION: The increases of COX-1, COX-2, mPGES-1 and EP1-2 in epithelial ovarian cancer, supports the hypothesis that PGE2-synthesis and signalling are of importance for malignant transformation and progression.

  • [Title] Expression of organic cation transporter SLC22A16 in human epithelial ovarian cancer: a possible role of the adriamycin importer.
  • 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] [Protein and mRNA expression of aquaporin-1 in epithelial ovarian tumors and its clinic significance].
  • OBJECTIVE: To investigate protein and mRNA expression of aquaporin-1 (AQP1) in epithelial ovarian tumors and its clinic significance.
  • METHODS: The protein and mRNA expressions of AQP1 were measured by immunohistochemical technique, western blot and RT-PCR in 65 cases of epithelial ovarian tumors and 13 cases of normal ovary tissue.
  • RESULTS: AQP1 located in microvascular and small vessel epithelial cells.
  • The protein and mRNA expressions of AQP1 in ovarian cancer (0.39 +/- 0.12, 0.93 +/- 0.51, respectively) and ovarian borderline tumors (0.43 +/- 0.21, 0.95 +/- 0.34, respectively) were significantly higher than that of ovarian benign tumors (0.27 +/- 0.13, 0.51 +/- 0.41, respectively; P < 0.05) and normal ovary tissue (0.24 +/- 0.13, 0.34 +/- 0.29, respectively; P < 0.05).
  • Of all ovarian cancers, expression of AQP1 in cases with ascites more than 1000 ml (0.46 +/- 0.13, 1.25 +/- 0.57, respectively) was higher than that of ascites less than 1 approximately 499 ml (0.35 +/- 0.11, 0.75 +/- 0.45, respectively; P < 0.05).
  • CONCLUSION: Over-expression of AQP1 plays an important role in development of epithelial ovarian tumors, and may be related with formation of ascites of ovarian carcinoma.

  • [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] 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.

  • [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.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [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] 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] Fine needle aspiration of borderline ovarian lesions. Is It useful?
  • Borderline ovarian tumors are a low grade form of epithelial ovarian carcinoma with a low rate of growth and a low potential to invade or metastasize.
  • According to the new World Health Organization classification, these tumors are placed between clearly benign and obviously malignant tumors because they exhibit some, but not all, of the morphologic features of malignancy.
  • For a distinction between borderline lesions and cystadenomas or carcinomas, 2 criteria are of the utmost importance: presence of nuclear atypia and absence of stromal invasion.
  • Although fine needle aspiration (FNA) is the most accurate diagnostic method in cytopathology, its value in the diagnosis of borderline lesions is limited, mainly because of its inability to establish the absence of stromal invasion.

  • [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] [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.

  • 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] 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.

  • [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.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [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.

  • 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.

  • In epithelial ovarian cancer (EOC), the expression of Smac/DIABLO decreased with the malignancy.
  • Thus, over-expression of Smac/DIABLO is a promising strategy for drug-resistant ovarian cancer treatment.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [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.

  • [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] Feasibility of ovarian cryopreservation in borderline ovarian tumours.
  • BACKGROUND: Borderline ovarian tumours (BOT) do not exhibit overt stromal invasion and are less aggressive than invasive epithelial ovarian tumours.
  • BOT also arise in younger patients than those who develop epithelial ovarian tumours.
  • Our aim was to evaluate the feasibility of ovarian cryopreservation (OC) in patients treated for BOT.
  • RESULTS: Twenty-three patients, treated between January 2002 and February 2008, were initially selected but six of them were excluded from the present study (four because the tumour was malignant and two because it was benign).
  • In eight cases, OC was not performed; instead, in four cases a simple cystectomy was finally performed (one patient was in fact pregnant at the time of surgery), in one case malignant disease was found and in three (18%) patients OC was not technically feasible because no normal ovarian parenchyma was evident on gross inspection.
  • In 18%, this procedure was aborted because no macroscopic healthy ovarian tissue could be found.

  • [Title] Primary ovarian mucinous cystic tumor with prominent theca cell proliferation and focal granulosa cell tumor in its stroma: case report, literature review, and comparison with Sertoli-Leydig cell tumor with heterologous elements.
  • 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.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • A case of 36-year-old nonmarried virgin woman presenting a giant ovarian serous cyst adenoma weighing 9.5 kg is reported here.
  • Ovarian neoplasms may be divided by origin cell type into three main groups: epithelial, stromal and germ cell.
  • Taken as a group, the epithelial tumors are by far the most common type.
  • The single most common benign ovarian neoplasm is the benign cystic teratoma; however, according to some studies it is serous cyst adenoma.
  • At laparotomy, a giant, totally cystic, vascularized and smooth mass attached to the right ovary was encountered, lying between the symphysis and the xiphoid.
  • This is the largest ovarian cyst that ever reported from our hospital and one of the largest among the reported cases in the literature.

  • Two hundred and thirty three cases of ovarian tumours and tumour like lesions were studied.
  • Of these 233 cases, 96 cases were of ovarian tumours and 137 were tumour like lesions of the ovary.
  • Of the 96 cases of ovarian tumours, 72.9% were benign, 4.1% were borderline and 22.9% were malignant.
  • Histologically surface epithelial tumours were the commonest (48.8%) followed by germ cell tumours (23.9%), sex cord stromal tumours (8.3%) and metastatic tumours (2.0%).
  • Ultrasound guided FNAC done in cases of ovarian tumours showed an accuracy of 100% for malignant lesions and 100% for benign and borderline lesions when compared with histopathological diagnosis.
  • Tuberculosis constituted (2.9%) cases and was the major cause of clinical diagnostic pitfalls for cases in which a clinical diagnosis of ovarian neoplasm was made.

  • [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.
  • 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] POLD2 and KSP37 (FGFBP2) correlate strongly with histology, stage and outcome in ovarian carcinomas.
  • BACKGROUND: Epithelial ovarian cancer (EOC) constitutes more than 90% of ovarian cancers and is associated with high mortality.
  • Improved insight into the molecular characteristics of the different subgroups of EOC is urgently needed, and should eventually lead to earlier diagnosis as well as more individualized and effective treatments.
  • Previously, we reported a limited number of mRNAs strongly upregulated in human osteosarcomas and other malignancies, and six were selected to be tested for a possible association with three subgroups of ovarian carcinomas and clinical parameters.
  • METHODOLOGY/PRINCIPAL FINDINGS: The six selected mRNAs were quantified by RT-qPCR in biopsies from eleven poorly differentiated serous carcinomas (PDSC, stage III-IV), twelve moderately differentiated serous carcinomas (MDSC, stage III-IV) and eight clear cell carcinomas (CCC, stage I-IV) of the ovary.
  • Superficial scrapings from six normal ovaries (SNO), as well as biopsies from three normal ovaries (BNO) and three benign ovarian cysts (BBOC) were analyzed for comparison.
  • The gene expression level was related to the histological and clinical parameters of human ovarian carcinoma samples.
  • CONCLUSIONS/SIGNIFICANCE: We have identified two biomarkers which are markedly upregulated in two subgroups of ovarian carcinomas and are also associated with stage and outcome.

  • [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] Carcinosarcoma-like mural nodule in intestinal-type mucinous ovarian of borderline malignancy: a case report.
  • Epithelial ovarian tumors of borderline malignancy are tumors with histologic features and biologic behavior between benign and frankly malignant epithelial ovarian neoplasms.
  • Here, we present a 35-year-old patient with carcinosarcoma-like mural nodule in intestinal-type mucinous ovarian tumor of borderline malignancy.
  • Foci of intraepithelial carcinoma (about 10%) without stromal invasion are also noted.
  • Total hysterectomy, bilateral salpingo-oophorectomy, appendectomy, and omentectomy were performed, and the frozen pathology during operation showed mucinous tumor of borderline malignancy of left ovary on April 18, 2002.
  • It is difficult to determine whether intestinal-type borderline mucinous tumors with intraepithelial carcinoma are associated with a worse prognosis compared with those with epithelial atypia alone due to disparate results in the published literature.
  • However, too few cases of carcinosarcoma-like mural nodule in mucinous tumor have been published to warrant a conclusion regarding their prognosis.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] LyGDI is a promising biomarker for ovarian cancer.
  • The aim of this study was to investigate the usefulness of LyGDI as a biomarker for the detection of ovarian cancer, and its specificity and sensitivity were compared with those of cancer antigen 125 (CA125).
  • METHODS: The serum levels of LyGDI were determined by enzyme-linked immunosorbent assay in 42 patients with ovarian disease, including 30 ovarian cancers and 12 benign ovarian lesions, and 76 healthy controls.
  • The expression of LyGDI was also evaluated by immunohistochemical staining in resected ovarian tissues of these patients.
  • RESULTS: The serum LyGDI level of cancers was significantly greater than those of the benign and healthy groups (P = 0.002 and P < 0.0001, respectively), whereas no difference was observed between the benign and control groups (P = 0.889).
  • Based upon receiver operating characteristic curve analysis, LyGDI levels were able to distinguish ovarian cancer from benign ovarian disease (P = 0.0001) and healthy control (P < 0.0001; areas under the receiver operating characteristic curves, 0.876 and 0.833, respectively).
  • For ovarian cancers, 83.3% (25/30) or 80.0% (24/30) was identified by serum LyGDI (> or = 1.5 ng/mL) alone or by CA125 (>35 U/mL) alone.
  • It is of particular importance to note that all cancer patients were identified by use of both markers, and the specificity was 83.3% for the benign group.
  • Immunohistochemical staining confirmed the expression of LyGDI on cancerous epithelial cells other than benign ovarian epithelium.
  • CONCLUSIONS: These results suggest that LyGDI has significant potential as a marker for detection of ovarian cancer in the patients with ovarian enlargement, including detection of early-stage cancers.
