  • [Title] Secretory cell outgrowth, PAX2 and serous carcinogenesis in the Fallopian tube.
  • The 'p53 signature' is a benign secretory cell outgrowth in the distal Fallopian tube that shares properties with ovarian serous cancer-including p53 mutations-and is a putative serous cancer precursor.
  • We expanded the precursor definition to all secretory cell outgrowths (SCOUTs) of 30 or more cells and scored normal (N) and altered (A) expression of both p53 and PAX2, a gene down-regulated in ovarian and endometrial cancer.
  • SCOUTs were identified by BCL2/p73 staining in tubes from women with serous carcinoma, inherited mutations in BRCA1 or BRCA2 and controls.
  • SCOUTs were prevalent in both proximal and distal tube and significantly associated with serous carcinoma versus the others (p < 0.001); 89% were PAX2 (A) and 26% were PAX2 (A)/p53 (A) (p53 signatures).
  • SCOUTs are discretely localized alterations commonly containing altered expression of multiple genes within histologically benign tubal epithelium.
  • This study reveals, for the first time, an entity (SCOUT) that is associated with serous cancer, expands the topography of altered PAX2 expression in the female genital tract mucosa and highlights another potential pathway disturbance involved in early serous carcinogenesis in the Fallopian tube.

  • [Title] Diagnostic utility of GLUT-1 expression in the cytologic evaluation of serous fluids.
  • STUDY DESIGN: Archival paraffin-embedded cell blocks of serous fluids from 25 cases of benign effusions containing reactive mesothelial cells and 39 cases of malignant effusions with metastatic adenocarcinoma (11 ovarian, 11 pulmonary, 9 gastrointestinal and 8 breast) were retrieved from the surgical pathology files.
  • Strong staining in at least 10% of the tumor cells was required in order to consider the case positive for the particular marker.
  • None (0 of 25) of the benign effusions expressed GLUT-1.
  • Benign effusions expressed CEA in 3 cases and B72.3 in 2 cases.
  • It can be used as a reliable component of an antibody panel to distinguish reactive mesothelial cells from metastatic adenocarcinoma in particular adenocarcinomas of body cavity effusions, in particular adenocarcinomas of ovarian and pulmonary origin.

  • [Title] Risk factors for benign serous and mucinous epithelial ovarian tumors.
  • OBJECTIVE: To investigate the risk factors for benign serous and mucinous epithelial ovarian tumors.
  • METHODS: Cases were women newly diagnosed with benign serous ovarian tumors (n=230) or benign mucinous tumors (n=133) between 2002 and 2005.
  • RESULTS: Current smoking was associated with a three-fold increase in risk of benign mucinous tumors (OR 3.25, 95% CI 1.97-5.34), and there was a trend of increasing risk with increasing amount smoked (P<.001).
  • Both recent obesity (OR 1.93, 95% CI 1.30-2.88) and obesity at age 20 (OR 4.38, 95% CI 1.88-10.20) were associated with increased risk of benign serous ovarian tumors, and having had a hysterectomy was also related to increased risk of serous (OR 2.75, 95% CI 1.90-3.96), but not mucinous tumors.
  • Ever having had a term pregnancy was inversely associated with both tumor types (combined OR 0.65, 95% CI 0.43-0.97), although greater numbers of pregnancies did not decrease risk further.
  • CONCLUSION: Our results suggest some differences in risk factors between benign serous and mucinous epithelial ovarian tumors and that risk factors for benign serous tumors differ from those well established for ovarian cancer.

  • [Title] Fascin expression in serous tumors of ovary correlates with aggressiveness of malignancy.
  • Ovarian serous tumors make up about one-fourth of all ovarian tumors.
  • There is a spectrum of proliferation and cellular atypia in these tumors with benign serous cystadenoma, borderline tumors, and low grade or type I serous carcinoma at the lower end and type II or high-grade serous papillary cystadenocarcinoma at the higher end.
  • The aim of this study was to investigate fascin expression in serous tumors of ovary and to evaluate its relationship with the aggressiveness of tumor.
  • Sections from a total of 66 serous tumors of ovary were collected including 26 serous carcinomas, 20 borderline serous tumors, and 20 benign serous cystadenomas.
  • Ten benign ovaries with inclusion cysts were used as controls.
  • Fascin expression was significantly increased in borderline (13/20, 65%) and malignant serous tumors (22/26, 84%) compared with benign serous cystadenoma (0/20) (P<0.001).
  • Fascin expression also correlated well with the tumor grade in serous carcinoma cases with 8/12 (66%) of grade I/II tumors staining positive compared with all 14 (100%) of grade III tumors showing fascin expression (P<0.05).
  • Our findings suggest that upregulation of fascin plays a role in increasing aggressiveness of serous ovarian tumors and could potentially be a molecular therapeutic target and a prognostic marker.

  • [Title] Ciliated adenocarcinoma of the ovary with evidence of serous differentiation: report of a case.
  • A patient with bilateral ovarian adenocarcinomas composed predominantly of ciliated cells incidentally found at autopsy is reported.
  • In one of the masses, the neoplastic cells seemed to arise from a serous adenofibroma.
  • The tumor was confined to the ovaries without evidence of metastatic spread.
  • Although morphologically resembling an endometrioid-type neoplasm, immunohistochemical and molecular studies were more consistent with a serous phenotype, especially in light of its apparent origination from a serous adenofibroma.
  • We agree with previous observations suggesting that although the neoplasm seems morphologically worrisome, it may actually portend a more benign clinical course.

  • [Title] Identification of novel variant, 1484delG in the 3'UTR of H3F3B, a member of the histone 3B replacement family, in ovarian tumors.
  • Previous studies have implicated the chromosomal region at 17q25 as harboring tumor suppressor genes based on the frequent loss of heterozygosity (LOH) observed in epithelial ovarian cancers (EOC).
  • In contrast to three other EOC cell lines (TOV81D, TOV112D and TOV21G) and primary cultures derived from normal ovarian surface epithelial cells (NOSE), sequence analysis of the cDNA revealed a deletion of G at position 1484 of the transcribed sequence which is located within the 3'UTR of H3F3B.
  • OV90 was derived from ascites fluid of an undifferentiated adenocarcinoma of ovarian origin.
  • The variant allele was identified in 1 of 65 (2%) healthy women with no prior history of cancer and in 5 participants with ovarian tumors comprising of 4 of 79 (5%) malignant EOC, none of 10 low malignancy potential tumors, and 1 of 8 (13%) benign tumors.
  • All carriers of the variant alleles were heterozygous and tumor samples did not exhibit preferential LOH of the normal allele.
  • The variant allele was identified in EOC samples of clear cell (1 of 20), mucinous (1 of 8), mixed cell (1 of 3) and undifferentiated (1 of 2) histopathological subtypes but none of 34 serous or 12 endometrioid subtype tumors.
  • One of 3 mucinous benign tumors also harbored the variant allele.
  • The functional significance of the variant is unknown, however its presence in rare subtypes of ovarian epithelial tumors warrants further investigation.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • 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.
  • The most common and best understood are serous borderline tumors and mucinous borderline tumors of intestinal type, which are the subject of this review.
  • 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.
  • All of these issues are discussed in this presentation, as are the important gross and microscopic features of serous and mucinous borderline tumors and pertinent information on their treatment and prognosis.

  • [Title] [CT features of ovarian Brenner tumor and a report of 9 cases].
  • OBJECTIVE: In order to improve the preoperative diagnostic accuracy, the computed tomographic (CT) features of ovarian Brenner tumor were described and analyzed.
  • METHODS: CT image and clinical data of nine patients with pathologically confirmed Brenner tumor were collected and analyzed retrospectively.
  • There were 8 benign lesions and 1 borderline lesion.
  • Among the nine cases, 5 were benign tumors with uniform structure, 3 were benign tumors accompanied with other pathological components, and 1 was borderline tumor.
  • On the CT images, the 5 uniform benign lesions showed to be solid tumor of low density (lower than that of muscle) or with small cyst inside, two of the 5 lesions had calcification, and other 2 lesions showed slightly heterogeneous enhancement after enhanced scanning.
  • The 3 benign Brenner tumors accompanied with other pathological structures were solid-cystic or cystic, with a clear demarcation of solid and cystic components.
  • The one borderline tumor was a heterogeneous solid one and its density was higher than that of muscle, with a large proportion of low density and large calcification, and moderately enhanced after enhancing.
  • CONCLUSION: Ovarian Brenner tumors are usually unilateral and often accompanied with other type of tumor components.
  • When a tumor is of uniform component, the CT imaging often shows a homogeneous solid tumor with homogeneous or heterogeneous density.
  • When a tumor is accompanied with other tumor components, it may be solid-cystic or cystic and has partial calcification.
  • After enhancing, a benign Brenner tumor is slightly enhanced, while the borderline one is moderately/highly enhanced.

  • [Title] HOXA7 in epithelial ovarian cancer: interrelationships between differentiation and clinical features.
  • Interrelationships between HOXA7 expression and ovarian cancer progression are investigated by cDNA array and by immunohistochemistry of normal ovaries and 538 epithelial ovarian tumor microarrays.
  • HOXA7 mRNA expression was higher in carcinomas than in benign tumors.
  • There were significant associations of strong HOXA7 staining of stroma and tumor nuclei with the clear cell histotype (stroma: P = .0022, nuclei: P = .0003) and of weak/absent staining with serous carcinomas.
  • Tumor E-cadherin expression correlated significantly with HOX7 staining in stroma (P = .0002) but not within tumors.
  • HOXA7 staining of tumor cell nuclei is correlated significantly with improved disease-specific survival (P = .0104), which is suggestive of the biological and potentially clinical importance of subcellular HOXA7 localization.

  • [Title] Distinct DNA methylation profiles in ovarian serous neoplasms and their implications in ovarian carcinogenesis.
  • OBJECTIVE: The purpose of this study was to analyze DNA methylation profiles among different types of ovarian serous neoplasm, which is a task that has not been performed.
  • STUDY DESIGN: The Illumina beads array (Illumina Inc, San Diego, CA) was used to profile DNA methylation in enriched tumor cells that had been isolated from 75 benign and malignant serous tumor tissues and 6 tumor-associated stromal cell cultures.
  • RESULTS: We found significantly fewer hypermethylated genes in high-grade serous carcinomas than in low-grade serous carcinoma and borderline tumors, which in turn had fewer hypermethylated genes than serous cystadenoma.
  • Unsupervised analysis identified that serous cystadenoma, serous borderline tumor, and low-grade serous carcinomas tightly clustered together and were clearly different from high-grade serous carcinomas.
  • CONCLUSION: The findings support the view that low-grade and high-grade serous carcinomas are distinctly different with low-grade, but not high-grade, serous carcinomas that are related to serous borderline tumor and cystadenoma.

  • 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] 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.
  • 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] Clinicopathological implications of inactivation of RASSF1A in serous epithelial ovarian cancers.
  • OBJECTIVE: To investigate the frequency of promoter hypermethylation of RASSF1A gene in ovarian cancers and its correlations to gene expression and clinicopathological characters in the Chinese population.
  • METHODS: In this study, we detected the frequency of promoter hypermethylation of the RASSF1A gene in 60 patients with primary serous epithelial ovarian carcinomas (SEOCs) using Methylation-Specific PCR (MSP).
  • RESULTS: The frequency of promoter hypermethylation of RASSF1A in Chinese primary SEOCs was 53.3%, whereas promoter hypermethylation was not found in normal ovarian tissues and benign ovarian tissues.
  • The inactivation of the RASSF1A gene due to hypermethylation in the promoter region might play a critical role in the pathogenesis of ovarian cancers.

  • RESULTS: Spectroscopy analysis of serous, mucinous and undifferentiated carcinoma of the ovary revealed Cho, lactate and lipid signals, but granulosa-theca cell tumor showed only a lipid signal.
  • The Cho signal was obtained from only 3 patients with mature cystic teratoma but none of the other benign ovarian tumors and pelvic abscesses.
  • A lipid signal was detected in 3 patients diagnosed with pelvic abscess and all benign ovarian tumors.
  • CONCLUSION: MRS demonstrates significant differences in metabolite concentration between benign and malignant ovarian tumors and pelvic abscesses.

  • [Title] Nidogen-2: a new serum biomarker for ovarian cancer.
  • OBJECTIVES: New ovarian cancer biomarkers suitable for early disease diagnosis, prognosis or monitoring could improve patient management and outcomes.
  • DESIGN AND METHODS: Nidogen-2 was measured by immunoassay in serum of 100 healthy women, 100 women with benign gynecological conditions and 100 women with ovarian carcinoma.
  • RESULTS: Serum nidogen-2 concentration between normal and benign disease patients was not different (median, 13.2 and 12.1 mg/L, respectively).
  • However, nidogen-2 concentration in serum of ovarian cancer patients was elevated (median, 18.6 mg/L; p<0.0001).
  • Both nidogen-2 and CA125 were elevated more in serous histotypes of ovarian cancer and late state disease.
  • CONCLUSIONS: Nidogen-2 is a new biomarker for ovarian cancer which correlates closely with CA125.

  • [Title] Anaplastic carcinoma associated with a mucinous cystic neoplasm of the pancreas during pregnancy: report of a case and a review of the literature.
  • We herein report an unusual case of anaplastic carcinoma occurring with a recurrent mucinous cystic neoplasm in a 38-year-old female.
  • A 10-cm retroperitoneal cystic mass was pointed out in the first pregnancy and a probable diagnosis of mucinous cystic neoplasm was made in October 2000.
  • During her second pregnancy in 2002, however, she presented hematemesis and underwent urgent distal pancreatectomy, splenectomy and partial resection of the gastric wall where the tumor perforated.
  • A diagnosis of borderline-type mucinous cystic neoplasm with ovarian-like stroma was made.
  • Nine months later, CT visualized a recurrent cystic tumor near the pancreatic stump, which was subsequently resected.
  • Pathology revealed that the tumor was composed of two different components of borderline-type mucinous cystic neoplasm and anaplastic carcinoma.
  • She survived four years after the second surgery without tumor recurrence.
  • Although the origin of anaplastic carcinoma has not been determined yet, it should be remembered that anaplastic carcinoma can occur in association with mucinous cystic neoplasm of more benign histology.

  • [Title] The role of actin bundling protein fascin in the progression of ovarian neoplasms.
  • PURPOSE OF INVESTIGATION: The aim of the study was to investigate the role of fascin in tumor progression and to investigate the role of fascin on endothelial cell migration and angiogenesis in ovarian neoplasms.
  • METHODS: In the study, 94 malign epithelial ovarian neoplasms, 13 borderline epithelial ovarian neoplasms, 25 serous and mucinous cystadenomas and four normal ovarian tissues were examined by means of immunohistochemistry, using monoclonal antihuman fascin antibody, clone IM20.
  • RESULTS: Total stromal fascin score in cases of borderline and malign epithelial ovarian tumors was significantly higher compared to normal ovaries and benign epithelial ovarian tumors (.000, p < 0.001).
  • There was no significant difference in terms of mean microvessel count and homogeneous or heterogeneous fascin expression of microvessels between the benign and malign groups (respectively p = .228 and p = .143).
  • CONCLUSIONS: This study suggests that up-regulation of fascin in tumoral tissue may promote invasion of ovarian carcinoma by cell-matrix adhesion.

  • [Title] [Correlation of hK6 expression with clinicopathological features and prognosis in epithelial ovarian cancer].
  • OBJECTIVE: To approach the relationship between the expression of hK6 in ovarian neoplasm and clinicopathological variables and prognosis in ovarian cancer patients for finding a new tumor marker of the ovarian cancer.
  • METHODS: The expression of hK6 was detected by immunohistochemistry in 19 cases of benign, 11 cases of borderline and 45 cases of malignant ovarian neoplasms and statistically analyzed whether its expression correlate with clinicopathological variables and prognosis in patients with ovarian cancer.
  • RESULTS: The expression of hK6 in ovarian cancer tissues (60.0%) was significantly higher than that in the benign (15.8%) and borderline (27.3%) ovarian neoplasm tissues (P < 0.01).
  • The expression of hK6 in higher-grade ovarian cancer tissues (68.4% ) was higher than that in low-grade ones (14.3%, P < 0.05).
  • CONCLUSION: The expression of hK6 in ovarian cancer was higher than that in benign and borderline ovarian neoplasms.
  • The expression of hK6 is higher in the ovarian cancer of late stage, higher-grade, with lymph node metastasis and is associated with a poorer prognosis. hK6 may become a new markers in prediction of prognosis of the patients with ovarian tumors.

  • [Title] Epidermal growth factor receptor expression in serous ovarian carcinoma: an immunohistochemical study with galectin-3 and cyclin D1 and outcome.
  • This study investigated the expression of epidermal growth factor receptor (EGFR), galectin-3 and cyclin D1 in a cohort of ovarian serous carcinomas with regard to outcome and clinicopathologic parameters.
  • Formalin-fixed paraffin-embedded archival tissues of fifty ovarian serous carcinomas were stained with anti-bodies to EGFR, Gal-3, and cyclin D1 by automated immunohistochemistry.
  • Additionally, 10 benign serous cystadenomas and 10 typical serous borderline ovarian tumors were included in the study.
  • The EGFR expression was scored negative in all serous cystadenomas and serous borderline ovarian tumors.
  • Membranous and cytoplasmic EGFR immunoreactivity was determined in 64% of ovarian serous carcinomas; it was related to high grade (P=0.0005) and poor outcome (P=0.0137) but not with stage (P=0.5118).
  • Galectin-3 and cyclin D1 immunostaining decreased from serous cystadenomas and serous borderline ovarian tumors to the carcinomas significantly (P=0.0022 and P=0.0083, respectively).
  • This study indicates that with regard to EGFR and cytoplasmic galectin-3 immunoexpression, multiple marker testing may be an adjunct in the identification of high-risk ovarian serous cancers.

  • [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] [Analysis of serum biomarkers of ovarian epithelial cancers based on 2-DE DIGE and MALDI TOF/TOF].
  • OBJECTIVE: To find new serum tumor markers for ovarian epithelial cancers by 2-DE DIGE and MALDI-TOF/TOF proteomic methods, in order to improve the diagnostic sensitivity and specificity.
  • METHODS: Serum samples from 103 cases of ovarian epithelial cancers, 60 cases of healthy women, 63 cases of benign ovarian tumors and 63 cases of benign pelvic diseases were collected.
  • Sera of 20 cases of ovarian epithelial cancers (A), 20 cases of ovarian benign tumors (B), 20 cases of pelvic benign diseases (C) and 20 cases of health control (D) were matched by age and pooled, respectively.
  • 2) Western blot and ELISA proved that there were significant differences in Hp and Tf between ovarian epithelial cancers and normal controls (P = 0.000), between ovarian epithelial cancers and ovarian benign tumors (P = 0.000), between ovarian epithelial cancers and benign pelvic disease sera (P = 0.000).
  • 3) CA125 + Hp + Tf combined detection of ovarian cancer had higher sensitivity and specificity than CA125, Hp or Tf detection alone.
  • CONCLUSION: Hp and Tf are differently expressed in the sera of patients with ovarian epitheliual cancers.
  • They can be used as serum biomarkers for ovarian epithelial cancers.
  • CA125 + Hp + Tf combined detection may improve the sensitivity and specificity of diagnosis of ovarian epithelial cancers.

  • [Title] Retinoid receptor alpha and Beta expression in serous ovarian tumors.
  • The expression of retinoid acid receptors alpha (RARalpha) and beta (RARbeta) and estrogen receptor alpha (ERalpha) was assessed by immunohistochemistry and Western blotting in normal ovaries, serous cystadenoma (n = 20), serous borderline (n = 14), and serous ovarian cancer (n = 47) and was correlated in cancer cases with stage, grade, progress-free survival (PFS), and survival.
  • RARalpha was increasingly expressed in benign cystadenomas, borderline, and low-stage and advanced-stage neoplasms (p < 0.001).
  • In stage III, G3 serous carcinoma, increased RARalpha expression was an independent prognostic factor associated with lower chemoresponse to first-line chemotherapy (taxol and carboplatin) and shorter PFS (p < 0.002).RARbeta and ERalpha expression did not correlate with RARalpha tumor characteristics or PFS and survival.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • RESULTS: By screening several other cancer cell lines with 27.F7 and 27.B1 we found consistently strong staining of other human cancer cell lines including SKOV-3 (an ovarian cancer cell line).
  • To further clarify the association of GIPC1 with breast and ovarian cancer we carefully studied 27.F7 and 27.B1 using immunocytochemical and immunohistochemical techniques.
  • An immunohistochemical study of normal ovarian tissue, benign, borderline and malignant ovarian serous tumors, and different types of breast cancer revealed high expression of GIPC1 protein in neoplastic cells.
  • Interestingly, antibodies 27.F7 and 27.B1 demonstrate differential staining of borderline ovarian tumors.
  • Examination of different types of breast cancer demonstrates that the level of GIPC1 expression depends on tumor invasiveness and displays a higher expression than in benign tumors.
  • CONCLUSION: The present pilot study demonstrates that the GIPC1 protein is overexpressed in ovarian and breast cancer, which may provide an important diagnostic and prognostic marker and will constitute the basis for further study of the role that this protein plays in malignant diseases.

  • [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).
  • This reduction in risk was most evident for serous invasive tumors.
  • 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] Expression of p53 protein phosphorylated at serine 20 and serine 392 in malignant and benign ovarian neoplasms: correlation with clinicopathological parameters of tumors.
  • The study investigated the expression of p53 protein phosphorylated at serine 20 (Ser20) and Ser392 and the association between clinicopathological parameters of ovarian neoplasms with respect to p53 protein overexpression.
  • METHODS: p53 protein expression was evaluated on tissues from malignant and benign ovarian tumors.
  • RESULTS: The correlation between p53 protein overexpression and p53-Ser392 phosphorylation was found in ovarian carcinomas (P = 0.001, r = +0.27).
  • In the total group of ovarian carcinomas, significant differences were observed in p53 protein overexpression between well (G1) and poor (G3) tumor grades (P = 0.005) and between serous and endometrioid types of tumor (P = 0.04), whereas p53-Ser20 phosphorylation was associated with advanced International Federation of Gynecology and Obstetrics stage (P = 0.004) and high tumor grade (P = 0.02).
  • In p53-positive ovarian carcinomas, p53-Ser392 phosphorylation was associated with advanced tumor stage (P = 0.02) and high tumor grade (P = 0.049).
  • p53-Ser20 phosphorylation was associated with low tumor grade of p53-positive ovarian carcinomas (P = 0.02) and with high tumor grade of p53-negative ovarian carcinomas (P = 0.02).
  • CONCLUSIONS: These results revealed that p53 phosphorylation at Ser20 and Ser392 is an early event in ovarian tumor development.
  • The authors suggest that the expression of p53 protein phosphorylated at Ser20 and Ser392 in ovarian carcinomas determines their individual clinical features depending on p53 protein status and may be useful biological biomarkers characterizing their behavior.

  • [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).
  • Patients with serous (n = 40) or mucinous tumors (n = 17) showed the highest total inhibin levels (P < 0.001).
  • At 95% specificity, the total inhibin assay detected 37 of 40 (93%) serous tumors and 16 of 17 (94%) mucinous tumors.
  • 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.
  • A significant decrease of total inhibin levels was shown in women with serous and mucinous carcinoma as result of surgery (P < 0.001).
  • 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] [Expression and clinical significance of uPA and PAI-1 in epithelial ovarian cancer].
  • However, their correlations to epithelial ovarian cancer have seldom been reported.
  • This study was to investigate the roles of uPA and PAI-1 in the invasion and metastasis of epithelial ovarian cancer, to clarify their localization and relationship with prognosis.
  • METHODS: Immunohistochemistry was applied to examine the protein expression of uPA and PAI-1 in 80 specimens of epithelial ovarian cancer and 20 specimens of benign ovarian tumor.
  • RESULTS: The positive rates of uPA and PAI-1 were significantly higher in epithelial ovarian cancer than in benign ovarian tumor (77.5% vs. 30.0%, P<0.001; 55.0% vs. 20.0%, P=0.005).
  • uPA expression was correlated positively to PAI-1 expression in epithelial ovarian cancer (P=0.001).
  • Higher positive rate of uPA was associated with greater metastatic tumor in the peritoneal cavity (P=0.038), but not associated with age, FIGO stage, histological type, pathologic grade, serum CA125 level, ovarian tumor size, and the size of residual tumor (P>0.05).
  • CONCLUSION: Both uPA and PAI-1 are up-regulated in epithelial ovarian cancer, and might be used as markers to predict the prognosis of epithelial ovarian cancer patients.

  • The present article describes the series of incident primary ovarian tumors in the Life Span Study (LSS) cohort of the Radiation Effects Research Foundation, with particular emphasis on case ascertainment and characterization of histological features of the tumors.
  • We identified 723 ovarian tumors (260 malignant, 463 benign) in 648 individuals of about 70,000 female LSS subjects; 71 cases had more than one ovarian tumor.
  • We histologically confirmed 601 tumors (182 malignant, 419 benign tumors).
  • The most frequent histological type was common epithelial tumor (90.7% for malignant and 59.7% for benign tumors).
  • The distributions of ovarian tumors by histological type were similar to those from other studies.
  • Among malignancies, the frequency of common epithelial types relative to other tumor types increased with radiation dose (p = 0.02).
  • Among benign tumors, the relative frequency of sex-cord stromal tumors increased with radiation dose (p = 0.04).
  • The women with mucinous cancer had better survival than those with serous cancers (p = 0.03).
  • Within tumor types, there was no consistent pattern of survival by radiation dose.
  • Variations in histological types of ovarian tumors in response to radiation dose, suggested by the case series data need to be followed up by population-based incidence analysis.

  • [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.
  • Histologic types are serous, mucinous, endometrioid, clear cell, or Brenner.
  • 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] Use of Ras-transformed human ovarian surface epithelial cells as a model for studying ovarian cancer.
  • 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 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] A serum based analysis of ovarian epithelial tumorigenesis.
  • OBJECTIVES: Ovarian epithelial carcinoma can be subdivided into separate histological subtypes including clear cell, endometrioid, mucinous, and serous.
  • This distinction could potentially be reflected in the levels of tumor produced factors that enter into the circulation and serve as biomarkers of malignant growth.
  • Here, we analyze levels of circulating biomarkers from a diverse set of patients diagnosed with ovarian carcinoma to identify biomarker trends and relationships associated with distinct carcinoma histotypes and divergent tumorigenic pathways.
  • METHODS: We utilize multiplexed bead-based immunoassays to measure serum levels of a diverse array of fifty-eight biomarkers from the sera of patients diagnosed with various histological subtypes of ovarian carcinoma and benign lesions.
  • Levels of each biomarker are compared statistically across carcinoma subtypes as well as with benign cases.
  • RESULTS: A total of 21 serum biomarkers differ significantly between patients diagnosed with ovarian carcinomas and benign cases.
  • Nine of these biomarkers are specific for carcinomas identified as clear cell, endometrioid, or mucinous in histology, while two biomarkers are specific for the serous histology.
  • Identified biomarkers include traditional and emerging tumor markers, cytokines and receptors, hormones, and adhesion- and metastasis-related proteins.
  • CONCLUSIONS: We demonstrate here that the divergent histology-based tumorigenic pathways proposed for ovarian epithelial carcinomas are associated with distinct profiles of circulating biomarkers.
  • Continued investigation into the relationships between these factors should reveal new insights into the complex mechanisms underlying ovarian epithelial tumorigenesis.

  • [Title] Immunohistochemical study of the expression of adhesion molecules in ovarian serous neoplasms.
  • To clarify possible roles of adhesion molecules including E-cadherin, beta- and gamma-catenin, CD44s, CD44v6, CD56, and CD99 in ovarian serous neoplasms, an immunohistochemical study was undertaken for 23 benign, 40 borderline, and 95 malignant ovarian serous neoplasms using tissue microarray (TMA).
  • Significantly reduced expression of E-cadherin, and overexpression of CD44s, CD56, and CD99 were more frequently observed in adenocarcinomas than in benign and borderline tumors.
  • Reduced expression of E-cadherin was also correlated with high tumor grade (P=0.03), presence of peritoneal seeding (P=0.03), and low overall survival rate (P=0.02).
  • Overexpression of CD44s was significantly associated with high tumor grade (P=0.04), advanced stage (P=0.03), and low overall survival rate (P=0.02).
  • Nuclear staining for gamma-catenin was correlated with tumor progression (P=0.004) and advanced International Federation of Gynecology and Obstetrics (FIGO) stage (P=0.02).
  • These results suggest that although E-cadherin, CD44s, CD56, and nuclear gamma-catenin immuno-expression seem to be useful prognostic markers for serous neoplasm of the ovary, CD44s expression and FIGO stage are independent prognostic factors.

  • [Title] An incidental peritoneal serous borderline tumor during laparoscopy for endometriosis.
  • BACKGROUND: Primary peritoneal serous borderline tumor (PPSBT) is an uncommon lesion, histologically indistinguishable from non-invasive peritoneal implants found in association with ovarian tumours of borderline malignancy.
  • CASE: A 37-year-old white woman was admitted for acute pelvic pain due to two 5 cm retrouterine bilateral ovarian cysts with an endometrioid aspect.
  • CONCLUSION: Although PPSBT is a rare entity, it is nonetheless important because of its macroscopic similarity to endometriosis and microscopic similarity to other peritoneal and mullerian proliferations of both benign and malignant biologic potential.

  • [Title] Detection of M2 macrophages and colony-stimulating factor 1 expression in serous and mucinous ovarian epithelial tumors.
  • Tumor-associated macrophages (TAM) are known to possess the immunosuppressive M2 macrophage phenotype.
  • They contribute to tumor growth, invasion, and metastasis by producing various mediators.
  • Macrophages, especially M2 polarized macrophages, preferentially express CD163 and CD204, but few studies have investigated macrophage phenotypes in human ovarian tumors.
  • The purpose of the present study was therefore to present results on macrophage differentiation in human ovarian serous and mucinous epithelial tumors.
  • The method focused on immunostaining of paraffin-embedded tumor samples.
  • Almost all macrophages infiltrating tumor tissues expressed CD163 and CD204, indicating the phenotypic shift toward M2 macrophage.
  • The numbers of CD68-positive macrophages as well as of CD163- and CD204-positive macrophages in borderline and malignant tumors were significantly higher than in benign tumors.
  • CSF-1 expression in malignant tumor cells was significantly higher than that in benign tumor cells and correlated with histological malignancy.
  • These results suggest that CSF-1 derived from tumor tissues induces macrophages to shift toward the M2 phenotype, which is considered to promote tumor growth.

  • [Title] Promoter methylation of sFRP5 in patients with ovarian clear cell adenocarcinoma.
  • BACKGROUND: Specific tumour suppressor genes with promoter methylation in ovarian clear cell adenocarcinoma (OCCA) can be one important epigenetic mark distinguishing OCCA from ovarian serous adenocarcinoma (OSA), benign endometriotic cysts and normal ovarian epitheliums.
  • MATERIALS AND METHODS: Five OCCA cell lines, 63 cancer tissues (48 OCCA and 15 OSA), 10 benign endometriotic cysts and five normal ovarian epitheliums were analysed by methylation-specific PCR using pooled DNAs to determine the methylation status of the promoter of the target genes, including genes for secreted frizzled-related proteins (sFRP1 to 5), adenomatous polyposis coli (APC), retinoblastoma protein 1 (Rb1), breast cancer 1 gene (BRCA1), p14(ARF), p15(INK4b), p16(INK4a) and survivin.
  • RESULTS: The sFRP5 promoter was significantly methylated in all OCCA cell lines, with 64.6% in OCCA tissues compared with 13.3% in OSA, and 0% in benign endometriotic cysts and normal ovarian epitheliums (P < 0.0001).

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Germ line and somatic mutations of BRAF V599E in ovarian carcinoma.
  • It has been shown that ovarian low-grade serous carcinoma evolves out of a stepwise progression from benign serous cystadenoma to serous borderline tumor (SBT) to micropapillary serous carcinoma (MPSC), and that BRAF activation is a very early somatic event in the tumorigenesis.
  • We postulated that BRAF could be a SBT susceptibility gene, and investigated both germ line and somatic mutations of BRAF V599E in 104 ovarian cancer patients.
  • BRAF V599E mutation in histologic samples was found in 5 (24%) of 21 SBTs, 1 (33%) of 3 MPSCs, 1 (17%) of 6 endometrioid carcinomas, but not detected in 42 conventional serous carcinomas, 12 mucinous borderline tumors, 10 mucinous, and 10 clear-cell carcinomas.
  • We also found no BRAF V599E mutation in 101 normal healthy women and 10 well-established ovarian cancer cell lines.
  • Our results suggest that BRAF gene plays a "gatekeeper" role but does not act as a predisposition gene in the development of low-grade serous carcinomas.

  • [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 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.

  • [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] Homozygous deletion of MKK4 in ovarian serous carcinoma.
  • Analysis of deleted chromosomal regions in tumors has historically led to the identification of tumor suppressor genes.
  • In this study, we used digital karyotyping, a genome-wide, high-resolution technology, to search for chromosomal deletions in ovarian serous carcinoma, the most lethal gynecological malignancy in women.
  • Five purified ovarian serous carcinomas were analyzed by digital karyotyping and small interstitial deletions at chromosome 17p were identified in two tumor samples.
  • Aligning these two deletions identified an overlapping region that spanned 2.4 Mb which harbored a candidate tumor suppressor gene, mitogen-activated protein kinase kinase-4 (MKK4).
  • Loss of heterozygosity of 17p occurred in 24 (86%) of 28 high-grade serous carcinomas including both cases with homozygous MKK4 deletion.
  • Additionally, downregulation of MKK4 expression was found in 96 (75%) of 128 ovarian serous carcinomas as compared to benign ovarian tissues.
  • These findings suggest that homozygous deletion or reduced expression of MKK4 may contribute to the development of ovarian serous carcinoma.

  • [Title] Vascular endothelial growth factor and its soluble receptor in benign and malignant ovarian tumors.
  • An imbalance between pro-angiogenic and anti-angiogenic factors is hypothesized in the pathogenesis of ovarian cystic disease.
  • The aim of the following study was to explore the possible role of free vascular endothelial growth factor receptor 1 (sVEGFR-1), a soluble regulator of vascular endothelial growth factor (VEGF) action, in ovarian cystoadenoma, endometriomata and cystoadenocarcinoma.
  • Forty-eight women, of whom fourteen had ovarian serous cysts, twenty-eight had stage III-IV ovarian endometriomata, and six had stage IIIB-IIIC ovarian carcinoma, were included.
  • Sampling of serum, peritoneal and ovarian cystic fluids and of tumor tissue was performed before, during and following surgery, respectively.
  • VEGF and sVEGFR-1 expression was evaluated in tumor tissue.
  • Western blot evidenced a marked expression of VEGF and soluble VEGFR-1 in endometriosis tissue with respect to benign cyst tissue but a lower expression of both molecules, contrary to that expected, in cancer tissue.
  • In conclusion, all in all, our data indicate that an excess of local VEGF with respect to its soluble receptor VEGFR-1 may be a key factor in the onset and maintenance of pathological neo-angiogenesis in ovarian cyst formation.

  • [Title] Myosin II co-chaperone general cell UNC-45 overexpression is associated with ovarian cancer, rapid proliferation, and motility.
  • Both tumor cell proliferation and metastasis are dependent on myosin II.
  • Because UNC-45 is required to chaperone the assembly of a functional myosin II motor, we examined the expression of the general cell (GC) UNC-45 isoform in ovarian tumors.
  • Serous carcinoma expressed elevated levels of GC UNC-45 compared with normal ovarian surface epithelium and benign cystadenoma.
  • High-stage exhibited greater GC UNC-45 expression than low-stage serous carcinoma.
  • Similarly, GC UNC-45 transcripts and protein levels were higher in ovarian cell lines than in immortalized ovarian surface epithelial cells.
  • Elevation of GC UNC-45 levels by ectopic expression enhanced the rate of ovarian cancer cell proliferation, whereas siRNA knockdown of GC UNC-45 suppressed proliferation without altering myosin II levels.
  • GC UNC-45 and myosin II also trafficked to the leading edges of ovarian cancer cells induced to move in a scratch assay.
  • Knockdown of GC UNC-45 reduced the spreading ability of ovarian cancer cells whereas it was enhanced by GC UNC-45 overexpression.
  • In sum, these findings implicate elevated GC UNC-45 protein expression in ovarian carcinoma proliferation and metastasis.

  • [Title] [Diagnostic problems of ovarian mucinous borderline tumors].
  • About 15-20% of all ovarian epithelial neoplasms are of borderline type (or atypical proliferative or carcinoma of low malignant potential) and about 5-7% are mucinous type, which are the second most common type behind the serous borderline tumors.
  • The borderline tumor is a serious diagnostic and treatment problem both for the pathologists and for clinicians.
  • These tumors appeared to be intermediate in their histologic and prognostic features between the benign cystadenomas and clearly malignant carcinomas.
  • To diagnose the intraepithelial carcinoma, to detect the microinvasion and the expansive invasion in a mucinous borderline tumor, to differentiate from the metastasis of colorectal tumors may be very problematic in the majority of the cases.
  • Eleven cases diagnosed as mucinous borderline ovarian tumor in our institute from 2000 to 2008 were reviewed.
  • We discuss all of these problems according to the latest literature and our experience, mentioning the problems of the peritoneal and ovarian pseudomyxomas.

  • [Title] PAX 2: a novel Müllerian marker for serous papillary carcinomas to differentiate from micropapillary breast carcinoma.
  • Ovarian serous papillary carcinoma, although rarely metastasizing to the breast, is often challenging based on morphology alone, particularly from the micropapillary variant of breast carcinoma.
  • Wilm's tumor gene 1 (WT-1) has been identified as a useful marker to differentiate metastatic ovarian serous papillary carcinoma from primary breast carcinoma; however, it has recently been shown in the micropapillary variant of the primary breast carcinoma making it a less specific marker.
  • PAX 2, a nuclear transcription factor, was recently observed in ovarian serous papillary carcinomas.
  • In addition, whole tissue sections of a variety of benign and neoplastic müllerian tissues were surveyed with the PAX 2 immunostain.
  • All cases were stained with rabbit polyclonal PAX 2 antibody and, in addition, the 5 metastatic ovarian serous carcinoma cases were stained with WT-1 as well for comparison.
  • All primary breast carcinomas represented on TMA-1 and TMA-2 were entirely negative for PAX 2 100% (89/89), whereas 100% (5/5) of all metastatic ovarian serous carcinomas showed moderate-to-strong staining.
  • PAX 2 expression was comparable with WT-1 as well in the metastatic ovarian serous carcinoma group.
  • We therefore conclude that PAX 2 is a promising new, sensitive, and specific müllerian immunomarker for ovarian serous carcinomas (primary and metastatic).

  • [Title] p53 autoantibodies as potential detection and prognostic biomarkers in serous ovarian cancer.
  • BACKGROUND: This study examined the value of serum p53 autoantibodies (p53-AAb) as detection and prognostic biomarkers in ovarian cancer.
  • This group included women subsequently diagnosed with invasive serous ovarian cancer (n = 60), nonserous ovarian cancers (n = 30), and women with benign disease (n = 30).
  • RESULTS: p53-AAb were detected in 25 of 60 (41.7%) of serous cases, 4 of 30 (13.3%) nonserous cases, 3 of 30 (10%) benign disease cases, and 10 of 120 (8.3%) controls (combined P = 0.0002).
  • p53-AAb did not significantly improve the detection of cases [area under the curve (AUC), 0.69] or the discrimination of benign versus malignant disease (AUC, 0.64) compared with CA 125 (AUC, 0.99) or HE4 (AUC, 0.98).
  • Detectable p53 antibodies in pretreatment sera were correlated with improved overall survival (P = 0.04; hazard ratio, 0.57; 95% confidence interval, 0.33-0.97) in serous ovarian cancer.
  • CONCLUSIONS: Antibodies to p53 are detected in the sera of 42% of patients with advanced serous ovarian cancer.

  • [Title] Stage-specific embryonic antigen 4 expression in epithelial ovarian carcinoma.
  • METHODS: In this study, we investigated the expression of SSEA-4 in 479 cases of various degrees of ovarian epithelial lesions by immunohistochemistry, consisting of 45 normal ovarian epithelia, 110 benign serous ovarian cystadenomas, 68 borderline serous ovarian cystadenomas, 104 invasive serous ovarian carcinomas, 64 benign serous mucinous cystadenomas, 48 borderline mucinous ovarian cystadenomas, and 40 invasive mucinous carcinomas.
  • RESULTS: The expression of SSEA-4 was found to be increased from normal epithelium to benign cystadenoma and to borderline cystadenoma and adenocarcinoma in both serous and mucinous group.
  • The loss or reduction of the expression of SSEA-4 was significantly correlated with more advanced tumor stage and poorer tumor cell differentiation.
  • CONCLUSIONS: We therefore proposed that SSEA-4 may play a role during the oncogenesis of epithelial ovarian carcinoma and posses a tumor suppressor effect during malignancy promotion.
  • It could be a potential therapy target in patients with epithelial ovarian carcinoma.

  • A 83-year-old woman received bilateral salpingo-oophorectomy and hysterectomy due to a provisional diagnosis of ovarian cystic tumor.
  • The tumor had a unilocular cystic cavity demonstrating serous cystadenoma and a solid mural nodule representing a biphasic pattern with mesenchymal and glandular components.
  • The glandular elements were composed of benign serous cells, whereas the mesenchymal components consisted of an admixture of fibromatous stromal cells without atypia and sarcomatous overgrowth.
  • After a 2-year follow-up, there were no signs of tumor recurrence or systemic disease.
  • To the authors' knowledge, this is the first reported case of adenofibrosarcoma originating from a mural nodule of ovarian serous cystadenoma.

  • [Title] [Expression of AIB1 protein in epithelial ovarian cancer cells and its impact on apoptosis].
  • OBJECTIVE: To investigate the expression of AIB1 (amplified in breast cancer 1) protein in epithelial ovarian cancer cells and to analyze the relationship between AIB1 protein and the apoptosis modulated proteins: P53 and Bcl-2.
  • METHODS: The expressions of AIB1, P53 and Bcl-2 proteins in 24 normal ovaries, 24 benign ovarian tumors, 18 borderline ovarian tumors and 69 epithelial ovarian cancers were examined with immunohistochemical method SP.
  • 1) The AIB1 protein expressed in 65.22% ovarian cancers, greater than in normal ovaries (8.33%), benign ovarian tumors (25.00%) and borderline ovarian tumors (38.89%).
  • The overexpression of AIB1 protein occurred in 36.23% ovarian cancers.
  • Ovarian cancers poorly-differentiated, at a late clinical stage and with lymph node involvement had higher AIB1 overexpression than those well-differentiated and moderately-differentiated, and those at an early clinical stage and without lymph node involvement.
  • 2) The expression of AIB1 was positively correlated with the expression of P53 (r = 0.342, P = 0.004) and Bcl-2 proteins (r = 0.311, P = 0.009) in the ovarian cancers.
  • CONCLUSION: AIB1 protein expression increases in ovarian cancers, which is associated with the higher malignant biological behavior.
  • The overexpression of AIB1 may be involved in the carcinogenesis and the development of epithelial ovarian cancers through a hormone independent pathway.

  • [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).

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Clinicopathological significance of DEK overexpression in serous ovarian tumors.
  • To investigate the significance of DEK protein expression in ovarian lesions, a total of 113 ovarian serous tumors, including 62 serous cystadenocarcinomas and 19 serous borderline tumors, were studied on immunohistochemistry.
  • For comparison, 32 benign serous tumors, including 12 serous papillary cystadenomas, 10 serous cystadenomas, and 10 serous surface papillomas, were also included.
  • DEK was positive in 93.5% of serous cystadenocarcinomas (58/62), 63.2% of serous borderline tumors (12/19), and weakly positive in 15.6% of benign serous tumors (5/32).
  • The strong positive signal was detected only in serous adenocarcinomas (80.6%, 50/62) and borderline tumors (21.1%, 4/19), but no serous benign tumors were strongly positive (0%, 0/32).
  • Meanwhile, the strong positivity rate of DEK protein was significantly higher in grade 2 and grade 3 than in grade 1 ovarian cancers (P < 0.05), but there was no significant association between DEK protein expression level and International Federation of Gynecology and Obstetrics (FIGO) stage of serous ovarian adenocarcinoma (P > 0.05).
  • In summary, DEK plays an important role in the progression of ovarian serous cancers.
  • The detection of DEK protein expression should be useful for the diagnosis and prognosis of ovarian serous cancers, and DEK might be a useful molecular target for ovarian cancer therapy.

  • [Title] The distal fallopian tube: a new model for pelvic serous carcinogenesis.
  • PURPOSE OF REVIEW: Research over the past 50 years has yielded little concrete information on the source of pelvic serous cancer in women, creating a knowledge gap that has adversely influenced our ability to identify, remove or prevent the earliest stages of the most lethal form of ovarian cancer.
  • RECENT FINDINGS: The distal fallopian tube is emerging as an established source of many early serous carcinomas in women with BRCA mutations (BRCA+).
  • Tubal intraepithelial carcinoma is present in many women with presumed ovarian or peritoneal serous cancer.
  • A candidate precursor to tubal intraepithelial carcinoma, entitled the 'p53 signature', suggests that molecular events associated with serous cancer (p53 mutations) may be detected in benign mucosa.
  • SUMMARY: A fully characterized precursor lesion is a first and necessary step to pelvic serous cancer prevention.
  • The emerging data offer compelling evidence for a model of 'fimbrial-ovarian' serous neoplasia, and call attention to the distal fallopian tube as an important source for this disease, the study of which could clarify pathways to cancer in both organs and generate novel strategies for cancer prevention.

  • [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] Unfavorable prognostic value of human kallikrein 7 quantified by ELISA in ovarian cancer cytosols.
  • Reports indicate that in ovarian cancer, KLK7 is significantly up-regulated at the mRNA level.
  • The aim of this study was to determine whether hK7, measured quantitatively by ELISA in ovarian cancer cytosols, is a prognostic biomarker for ovarian cancer.
  • METHODS: We used a newly developed ELISA with 2 monoclonal antibodies to quantify hK7 production in 260 ovarian tumor cytosols and correlated these data with various clinicopathologic variables and patient outcomes [progression-free survival (PFS) and overall survival (OS)] over a median follow-up period of 52 months.
  • RESULTS: Median (range) hK7 concentration in ovarian tumor cytosols was 2.84 (0-32.8) ng/mg of total protein.
  • Compared with healthy and benign ovarian tissues and nonovarian tumors that metastasized to the ovary, malignant ovarian tumor cytosols highly overproduced hK7 (P <0.001).
  • Women with hK7-positive tumors most frequently had advanced-stage disease, higher tumor grade (G3), suboptimal debulking, and serous or undifferentiated histotype (P <0.001).
  • CONCLUSIONS: hK7 is associated with other unfavorable characteristics of ovarian cancer, but it is not an independent prognosticator for ovarian cancer.

  • [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.
  • 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] N-acetyl resonances in in vivo and in vitro NMR spectroscopy of cystic ovarian tumors.
  • We demonstrated the presence of this resonance with in vivo MRS in the cyst fluid of a patient with an ovarian tumor. (1)H-NMRS on the aspirated cyst fluid of this patient confirmed the observation.
  • It was also present in 11 additional ovarian cyst fluid samples randomly chosen from our biobank.
  • GC-MS independently confirmed the presence of NAA in high concentration in the three samples, which all derived from benign serous tumors.
  • We conclude that both NAA and N-acetyl groups from glycoproteins and/or glycolipids may contribute to the delta 2.0-2.1 ppm resonance complex in ovarian cyst fluid.
  • This spectral region seems to contain resonances from biomarkers that provide relevant clinical information on the type of ovarian tumor.

  • [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.
  • 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.

  • [Title] p63 expression in epithelial ovarian tumors.
  • Ovarian cancer is a highly lethal disease and its underlying biology is poorly understood.
  • The p63 is a homologue gene of the tumor suppressor p53. p63 appears to be important for the development and differentiation of reproductive epithelium and interacts with p53 in human tumorigenesis.
  • This study presents the immunoexpression of the p63 in benign and malignant epithelial ovarian tumors.
  • We evaluated the p63 immunoexpression in 91 ovarian benign cystadenomas (29 mucinous and 62 serous) and in 29 ovarian malignant tumors (3 mucinous borderline, 3 serous borderline, 17 serous carcinomas, 2 endometrioid, 2 undifferentiated, 1 mucinous, and 1 clear-cell carcinoma) using a monoclonal antibody clone 4A4 (1:200), which recognizes all p63 variants.
  • We observed 85.7% of positivity in benign tumors, 50% in borderline tumors, and 8.7% in invasive ovarian cancer (P < .0001).
  • The benign serous cystadenomas were positive in 91.9% of cases and benign mucinous cystadenomas in 72.4% (P= .02).
  • These data suggests an important role of p63 in the control of ovarian epithelium behavior.
  • The p63 may be involved in the development of benign and malignant epithelial ovarian tumors.

  • [Title] B7-H4 overexpression in ovarian tumors.
  • OBJECTIVES: Despite great advances in therapeutic management, the mortality rate for ovarian cancer has remained relatively stable over the past 50 years.
  • This study was designed to evaluate the expression of B7-H4 protein, recently identified as a potential molecular marker of breast and ovarian cancer by quantitative PCR analysis, in benign tumors, tumors of low malignant potential and malignant tumors of the ovary.
  • METHODS: Archival formalin-fixed tissue blocks from serous, mucinous, endometrioid and clear cell ovarian tumors were evaluated by immunohistochemistry for the distribution of B7-H4 expression, and staining intensity was measured by automated image analysis.
  • RESULTS: B7-H4 cytoplasmic and membranous expression was detected in all primary serous (n = 32), endometrioid (n = 12), and clear cell carcinomas (n = 15), and in all metastatic serous (n = 23) and endometrioid (n = 7) ovarian carcinomas.
  • The proportion of positive cells and median staining intensity was greater in serous carcinomas than in serous cystadenomas or serous tumors of low malignant potential, and the differences were statistically significant (P < 0.0001 and P = 0.034, respectively).
  • CONCLUSIONS: The consistent overexpression of B7-H4 in serous, endometrioid and clear cell ovarian carcinomas and the relative absence of expression in most normal somatic tissues indicates that B7-H4 should be further investigated as a potential diagnostic marker or therapeutic target for ovarian cancer.

  • [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.
  • Oct4 overexpression was associated with more advanced FIGO stage and higher histological grade in serous adenocarcinoma.
  • 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] Overexpression of CEACAM6 in borderline and invasive mucinous ovarian neoplasms.
  • OBJECTIVE: Identifying markers specific for mucinous ovarian neoplasms (MON) is important for cancer diagnosis and surveillance, and will help improve our general understanding of the pathobiology of these tumors.
  • METHODS: Western blot compared CEACAM6 expression in normal human ovarian surface epithelium (HOSE) and ovarian cancer cell lines.
  • Quantitative RT-PCR (qRT-PCR) was performed on 75 laser-microdissected HOSE and ovarian cancer tissue samples.
  • Expression was absent in all 2 HOSE, 7 serous cancer, and 2 clear cell cancer cell lines.
  • 100-fold CEACAM6 overexpression (qRT-PCR) was demonstrated in 13/16 (81%) borderline, low-grade, and high-grade invasive MON's, compared to 5/50 (10%) serous and 1/5 (20%) benign mucinous samples.
  • CEACAM6 expression was not different between borderline and invasive MON's (p=0.55) or across tumor stage (p=0.76).
  • None of the serous or benign mucinous tumors exhibited CEACAM6 staining.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • AIM: We used a new differential display method, the annealing control primer (ACP) system, to analyse the differentially expressed genes in mucinous ovarian tumours.
  • 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.
  • Galectin-3 expression was more frequent in clear cell carcinomas, serous tumours and mucinous tumours than in endometrioid and transitional 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] Overexpression of mammaglobin B in epithelial ovarian carcinomas.
  • OBJECTIVE: Mammaglobin B is a uteroglobin gene family member recently found highly differentially expressed in serous papillary ovarian cancer by gene expression profiling.
  • In order to evaluate its potential as a novel ovarian cancer biomarker, in this study we quantified and compared Mammaglobin B expression in various histologic types of epithelial ovarian carcinomas (EOC).
  • METHODS: Mammaglobin B expression was evaluated by real-time PCR and/or immunohistochemistry in fresh-frozen biopsies and paraffin-embedded tissues derived from a total of 137 patients including 69 primary EOC with different histologies, 28 serous papillary omental metastasis, 8 borderline tumors, 26 benign cystadenomas and 14 normal ovaries.
  • RESULTS: High levels of Mammaglobin B gene expression were detected in 100% (68 out of 68) of the ovarian cancer biopsies tested by real-time PCR.
  • In contrast, normal human ovarian surface epithelium (HOSE) expressed negligible levels of Mammaglobin B mRNA (EOC versus HOSE, p<0.01).
  • Although Mammaglobin B gene expression levels were higher in endometrioid, mucinous and undifferentiated tumors when compared to serous papillary tumors, clear cell tumors and those with mixed histology, these differences were not statistically significant.
  • In agreement with real-time PCR results, EOC were found to express significantly higher levels of Mammaglobin B protein when compared to normal ovaries and benign cystadenomas (p<0.01).
  • CONCLUSIONS: Mammaglobin B gene is highly expressed in EOC and may represent a novel molecular marker for multiple histological types of ovarian cancer.
  • Additional studies to evaluate the clinical utility of Mammaglobin B as a diagnostic and/or therapeutic target in ovarian cancer are warranted.

  • In cervical squamous lesions, p16 is positive in most high-grade cervical intraepithelial neoplasia (CIN) and in some cases of low-grade CIN, usually those associated with high-risk HPV. p16 may be useful to identify small focal high-grade CIN lesions, to distinguish some cases of CIN involving immature metaplastic squamous epithelium from immature metaplastic squamous epithelium not involved by CIN and to distinguish high-grade CIN from benign mimics.
  • In cervical glandular lesions, p16 is useful, as part of a panel, in the distinction between adenocarcinoma in situ (diffusely positive) and benign mimics, including tuboendometrial metaplasia and endometriosis, which are usually p16-negative or focally positive. p16 may be used, in combination with other markers, to distinguish between a cervical adenocarcinoma (diffuse positivity) and an endometrioid-type endometrial adenocarcinoma (negative or focally positive).
  • Some uterine serous carcinomas are diffusely positive.
  • Metastatic cervical adenocarcinomas in the ovary are usually diffusely p16-positive, and because these may closely mimic a primary ovarian endometrioid or mucinous adenocarcinoma, this may be a valuable diagnostic aid, although p16 expression in primary ovarian adenocarcinomas of these morphologic subtypes has not been widely investigated.
  • Some ovarian serous carcinomas, similar to their uterine counterparts, are p16-positive.

  • [Title] The role of activin A and Akt/GSK signaling in ovarian tumor biology.
  • Elevated activin A levels in serum, cyst fluid, and peritoneal fluid of ovarian cancer patients suggest a role for this peptide hormone in disease development.
  • We hypothesize that activin A plays a role in ovarian tumor biology, and analyzed activin-mediated pro-oncogenic signaling in vitro and the expression of activin signaling pathway molecules in vivo.
  • To validate in vitro observations, immunostaining of the betaA-subunit of activin A and phospho-GSKalpha/beta (Ser9/21) was performed, and the correlation between immunoreactivity levels of these markers and survival was evaluated in benign serous cystadenoma, borderline tumor, and cystadenocarcinoma microarrays.
  • Analysis of tissue microarrays revealed that betaA expression in epithelia did not correlate with survival or malignancy, but expression was elevated in stromal cells from carcinomas when compared with benign tumors.
  • Phospho-GSKalpha/beta (Ser9/21) staining was more intense in mitotically active carcinoma cells and exhibited a polarized localization in benign neoplasms that was absent in carcinomas.
  • Our data are consistent with a model in which activin A may mediate ovarian oncogenesis by activating Akt and repressing GSK to stimulate cellular proliferation.

  • [Title] A candidate precursor to serous carcinoma that originates in the distal fallopian tube.
  • The tubal fimbria is a common site of origin for early (tubal intraepithelial carcinoma or TIC) serous carcinomas in women with familial BRCA1 or 2 mutations (BRCA+).
  • We recently identified foci of strong p53 immunostaining-termed 'p53 signatures'-in benign tubal mucosa from BRCA+ women.
  • Laser-capture microdissected and polymerase chain reaction-amplified DNA revealed reproducible p53 mutations in eight of 14 fully-analysed p53 signatures and all of the 12 TICs; TICs and their associated ovarian carcinomas shared identical mutations.
  • This is the first report of an early and distinct alteration in non-neoplastic upper genital tract mucosa that fulfils many requirements for a precursor to pelvic serous cancer.
  • The p53 signature and its malignant counterpart (TIC) underline the significance of the fimbria, both as a candidate site for serous carcinogenesis and as a target for future research on the early detection and prevention of this disease.

  • [Title] Cyclooxygenase 2 expression in serous tumors of the ovary.
  • This study was designed to investigate the expression of cyclooxygenase (COX)-2 in ovarian serous tumors (benign, borderline tumors, and carcinomas) and primary peritoneal serous carcinomas.
  • Cases diagnosed between 1995 and 2001 were reviewed; 47 benign tumors, 6 borderline tumors, and 39 carcinomas were examined, as well as 12 normal ovaries that served as controls.
  • Normal ovarian and tubal epithelium, inclusion cysts, benign serous tumors, and borderline tumors had a uniform score 3 staining pattern.
  • Serous ovarian carcinomas had variable staining scores, tending to correlate with the level of tumor differentiation.
  • In conclusion, COX-2 expression is present in serous tumors, including benign tumors, borderline tumors, and carcinomas.
  • The clinical utility of these findings is related to the potential role of nonsteroidal anti-inflammatory drugs, which are COX-2 inhibitors, in treating and/or preventing some forms of ovarian carcinoma.

  • [Title] Pediatric ovarian malignancy presenting as ovarian torsion: incidence and relevance.
  • PURPOSE: With ovarian torsion, concern for underlying malignancy in the enlarged ovary has previously driven surgeons to resection.
  • However, the incidence of malignancies presenting as ovarian torsion is not documented.
  • METHOD: After institutional review board exemption (IRB#-022008-095), a 15(1/2)-year retrospective review was conducted to identify cases of operative ovarian torsion in our medical center.
  • Tumors with neoplastic pathology (malignant and benign) were analyzed and compared with all reported cases in the literature.
  • RESULTS: A total of 114 patients (mean +/- SEM age, 10 years, 2 days to 19 years +/- 0.53) with operatively proven ovarian torsion were identified.
  • Four malignancies (3.5%) and 26 benign neoplasms (23%) were present in this age group.
  • Malignancies consisted of serous borderline tumors (2), juvenile granulosa cell tumor (1), and dysgerminoma (1).
  • The literature yielded a total of 593 cases of operative ovarian torsion with 9 (1.5%) malignancies and 193 (33%) benign neoplasms.
  • The malignancies were juvenile granulosa cell tumor (n = 4), dysgerminoma (n = 2), serous borderline tumors (n = 2), and 1 undifferentiated adenocarcinoma.
  • CONCLUSION: By combining our series with 13 in the literature, a 1.8% malignancy rate occurred in 707 patients with ovarian torsion, markedly less than the reported malignancy rate of 10% in children with ovarian masses.
  • These data further support the implementation of operative detorsion and close postoperative ovarian surveillance, with reoperation for persistent masses.
  • Further study is needed to determine if delaying resection by weeks in those cases of persistent masses would result in tumor progression and thus change prognosis.

  • [Title] Ovarian adenosarcoma arising from benign cystadenoma and associated intraoperative consultation pitfalls.
  • An unusual case of ovarian adenosarcoma arising from a smooth-walled serous cystadenoma is described.
  • The malignant component was underdiagnosed during frozen section examination as benign cystadenoma because of the deceptively benign gross appearance of the tumor.
  • The malignant component could not be distinguished from the benign component using immunohistochemical analysis.
  • To our knowledge, this is the first reported case of an adenosarcoma arising from a grossly benign cystadenoma and the third case in the literature of an adenosarcoma associated with a cystadeno(fibro)ma.
  • This case also shows the challenges in differentiating adenosarcoma from a benign counterpart on both frozen and permanent sections.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Rapid mass spectrometric metabolic profiling of blood sera detects ovarian cancer with high accuracy.
  • BACKGROUND: Ovarian cancer diagnosis is problematic because the disease is typically asymptomatic, especially at the early stages of progression and/or recurrence.
  • We report here the integration of a new mass spectrometric technology with a novel support vector machine computational method for use in cancer diagnostics, and describe the application of the method to ovarian cancer.
  • METHODS: We coupled a high-throughput ambient ionization technique for mass spectrometry (direct analysis in real-time mass spectrometry) to profile relative metabolite levels in sera from 44 women diagnosed with serous papillary ovarian cancer (stages I-IV) and 50 healthy women or women with benign conditions.
  • Because of the extremely low prevalence of ovarian cancer in the general population (approximately 0.04%), extensive prospective testing will be required to evaluate the test's potential utility in general screening applications.
  • IMPACT: The ability to accurately and inexpensively diagnose ovarian cancer will have a significant positive effect on ovarian cancer treatment and outcome.

  • [Title] Maspin overexpression correlates with positive response to primary chemotherapy in ovarian cancer patients.
  • Experimental studies revealed that maspin suppresses tumor growth, angiogenesis, invasion and metastasis.
  • We examined maspin expression in human ovarian tumors and relation between maspin expression and clinicopathological features as well as the role of maspin in predicting clinical outcome in patients with ovarian cancer.
  • METHODS: Tissue samples consisted of 42 benign tumors, 10 borderline (LMP) tumors, 76 ovarian carcinomas, 8 Krukenberg tumors and 32 normal tissues.
  • RESULTS: Relative maspin level was significantly higher in patients with LMP tumors (median 0.74) and early stages ovarian cancers (median 0.46) when compared with healthy tissues (median 0.03), those with benign (median 0.23) and metastatic tumors (median 0.22).
  • Overexpression of maspin was found to correlate with the early stage of the disease (p=0.001), non-serous subtype of ovarian cancer (p=0.03) and positive response to chemotherapy (p=0.02).
  • CONCLUSIONS: Maspin is upregulated in borderline tumors and the early stages of ovarian carcinoma and then significantly downregulated with malignant transformation.
  • High expression may paradoxically promote the invasion and metastasis of ovarian carcinomas.
  • Our study revealed that maspin expression could play an important role in predicting the results of treatment of ovarian cancer patients.

  • [Title] DNA fragmentation factor (DFF45): expression and prognostic value in serous ovarian cancer.
  • This study investigated the expression of DNA fragmentation factor (DFF45), MIB-1, and p53 in formalin-fixed, paraffin-embedded archival tissues of 50 ovarian serous carcinomas.
  • In addition, 10 benign serous cystadenomas and 10 serous neoplasms of low malignant potential (LMP) were included in this DFF45 immunostudy.
  • For p53, at least 10% of tumor cells had to display nuclear staining to consider a case positive.
  • Low DFF45 expression was identified in all serous cystadenomas and in LMPs, as well as in 18 (36%) ovarian serous carcinomas.
  • This study indicates that DFF45 expression is frequently upregulated in ovarian serous carcinomas and may serve as a marker of aggressive behavior with prognostic value.

  • [Title] Pediatric borderline ovarian tumors: a retrospective analysis.
  • BACKGROUND/PURPOSE: Borderline ovarian tumors (BOTs) are uncommon in the pediatric population, and there have been limited studies that have included a small number of patients.
  • RESULTS: Twenty-nine patients (median age, 18 years) had a large-sized tumor (median, 19.8 cm).
  • The permanent section histology revealed 25 mucinous (86.2%) and 4 serous type tumors (13.8%).
  • In 2 cases, the suspected recurrences were found to be other benign ovarian tumors.
  • In one case that was initially treated with left ovarian cystectomy for a mucinous BOT, subsequent left salpingo-oophorectomy confirmed recurrence of a mucinous BOT at 16-month follow-up.
  • The last case was a newly developed primary ovarian mucinous carcinoma with no evidence of recurrence of a previous mucinous BOT at 26-month follow-up.

  • [Title] Overexpression of kallikrein 10 (hK10) in uterine serous papillary carcinomas.
  • The goal of this study was to investigate the expression and secretion levels in vitro and in vivo of kallikrein 10 in uterine serous papillary carcinoma, a highly aggressive variant of endometrial tumor.
  • STUDY DESIGN: Human kallikrein 10 gene expression levels were evaluated in 11 snap-frozen uterine serous papillary carcinoma biopsies and 6 normal endometrial cell biopsies by real-time polymerase chain reaction.
  • Secretion of kallikrein 10 protein by 10 primary tumor cultures including 3 uterine serous papillary carcinomas, 2 endometrioid carcinomas, and 5 ovarian serous papillary tumors was measured using a sensitive ELISA.
  • Finally, kallikrein 10 concentration in 75 serum and plasma samples from 22 healthy women, 20 women with benign diseases, 21 women with endometrioid carcinomas, and 12 uterine serous papillary carcinoma patients was studied.
  • RESULTS: Kallikrein 10 gene expression levels were significantly higher in uterine serous papillary carcinoma when compared with normal endometrial cell biopsies (mean copy number by real time polymerase chain reaction = 743 versus 1.4; uterine serous papillary carcinoma versus endometrioid carcinoma: P < .02).
  • In vitro kallikrein 10 secretion was detected in all primary uterine serous papillary carcinoma cell lines tested (mean = 2.7 microg/L), and the secretion levels were not significantly different to those found in primary ovarian serous papillary tumor cultures (mean 4.2 microg/L).
  • Kallikrein 10 serum and plasma concentrations (microg/L; mean +/- SEM) among normal healthy females (0.6 +/- 0.04), patients with benign diseases (0.6 +/- 0.06), and patients with endometrioid carcinomas (0.7 +/- 0.06) were not significantly different.
  • In contrast, serum and plasma kallikrein 10 values in uterine serous papillary carcinoma patients (1.2 +/- 0.1) were significantly higher than those in the non-cancer group (P = .002), benign group (P = .002), and endometrioid carcinoma patients (P = .005).
  • CONCLUSION: Kallikrein 10 is highly expressed in uterine serous papillary carcinoma, and it is released in the plasma and serum of uterine serous papillary carcinoma patients.
  • Kallikrein 10 may represent a novel biomarker for uterine serous papillary carcinoma.

  • [Title] Reprogramming of the transcriptome in a novel chromosome 3 transfer tumor suppressor ovarian cancer cell line model affected molecular networks that are characteristic of ovarian cancer.
  • Tumor suppression as a consequence of the transfer of chromosome 3p fragments was previously observed in a novel epithelial ovarian cancer (EOC) OV-90 cell line model harboring loss of 3p.
  • Microarray analysis revealed that tumor suppression was associated with a modified transcriptome.
  • To investigate the relevance of the altered transcriptome, the differentially expressed genes identified by Affymetrix analysis in the 3p transfer studies, were integrated with a comparative microarray analysis of normal ovarian surface epithelial (NOSE) cells and malignant ovarian (TOV) cancers.
  • The investigation of these genes in benign serous ovarian tumors and EOC cell lines also exhibited predictable expression patterns.
  • Within the group of differentially expressed genes were SPARC, DAB2, CP, EVI1, ELF3, and EHD2, known to play a role in ovarian cancer, genes implicated in other cancers, such as GREM1 and GLIPR1, as well as genes not previously reported in a cancer context such as AKAP2 and ATAD4.
  • These findings suggest that the reprogramming of the transcriptome that occurred as a consequence of the chromosome 3 transfer and tumor suppression affected molecular networks that are characteristic of ovarian carcinogenesis thus validating our novel ovarian cancer cell line model.

  • [Title] Proteomic-based discovery and characterization of glycosylated eosinophil-derived neurotoxin and COOH-terminal osteopontin fragments for ovarian cancer in urine.
  • PURPOSE: The objective was to identify and characterize low molecular weight proteins/peptides in urine and their posttranslational modifications that might be used as a screening tool for ovarian cancer.
  • EXPERIMENTAL DESIGN: Urine samples collected preoperatively from postmenopausal women with ovarian cancer and benign conditions and from nonsurgical controls were analyzed by surface-enhanced laser desorption/ionization mass spectrometry and two-dimensional gel electrophoresis.
  • Quantitative and semiquantitative ELISAs were developed for preliminary validation in patients of 128 ovarian cancer, 52 benign conditions, 44 other cancers, and 188 healthy controls.
  • RESULTS: A protein (m/z approximately 17,400) with higher peak intensities in cancer patients than in benign conditions and controls was identified and subsequently defined as eosinophil-derived neurotoxin (EDN).
  • A glycosylated form of EDN was specifically elevated in ovarian cancer patients.
  • Modified forms EDN and osteopontin fragments were elevated in early-stage ovarian cancers and a combination of both resulted to 93% specificity and 72% sensitivity.
  • CONCLUSIONS: Specific elevated posttranslationally modified urinary EDN and osteopontin COOH-terminal fragments in ovarian cancer might lead to potential noninvasive screening tests for early diagnosis.

  • [Title] Erythropoietin receptor function and expression in epithelial ovarian carcinoma.
  • OBJECTIVE: Our objectives were to determine if the erythropoietin receptor (EpoR) has increased expression in epithelial ovarian carcinoma, and if erythropoietin (Epo) confers malignant properties to ovarian cancer cell lines.
  • METHODS: A Western blot analysis of protein lysates from normal ovarian surface epithelial cells and ovarian cancer cell lines was performed.
  • In addition, immunohistochemical (IHC) staining for EpoR in tissue specimens of normal, low malignant potential tumor, and epithelial ovarian carcinoma was performed.
  • Epo effect on ovarian cancer cell lines was investigated by a cytotoxicity assay using a cell line with high (OVCAR3) and low (SKOV3) EpoR expression.
  • RESULTS: Western blot analysis revealed increased expression of EpoR in multiple ovarian cancer cell lines.
  • IHC staining revealed limited EpoR expression in benign ovarian tissue and increased levels in ovarian low malignant potential (LMP) tumor and carcinoma.
  • This difference between benign ovarian tissue and carcinoma was found to be statistically significant using a quantitative scoring system.
  • CONCLUSION: Increased EpoR expression in ovarian LMP tumors and carcinoma is demonstrated by Western blot analysis and IHC staining.
  • Furthermore, adversely effects sensitivity to cisplatin in the ovarian cancer cell lines.

  • BACKGROUND: Cystic tumors of ovary, whether benign, borderline, or malignant may be associated with mural nodule of various types, including sarcomas, sarcoma-like mural nodules (SLMN), and foci of anaplastic carcinoma.
  • Cases of serous borderline ovarian tumor with mural nodules of mixed type are very rare.
  • Left ureter was found to be dilated because of the infiltration of distal part by the tumor, so distal ureteral resection and neoureterocystostomy were performed.
  • Final pathology revealed borderline serous ovarian tumor with mural nodules which were consisted of SLMNs, multiple and sharply demarcated from the adjacent tumor, and sarcomatous nodules showing infiltrative appearance in metastatic regions.

  • [Title] Persistent megalocystic ovary following in vitro fertilization in a postpartum patient with polycystic ovarian syndrome.
  • OBJECTIVE: Ovarian hyperstimulation syndrome (OHSS) is more severe when pregnancy occurs, as the developing pregnancy produces human chorionic gonadotropin, which stimulates the ovary's persistent growth.
  • However, 1 month after delivery, the bilateral ovary had not shrunk, and levels of tumor markers CA125 and CA199 were 50.84 and 41.34 U/mL, respectively.
  • At laparotomy for suspected malignancy, both adnexae formed "kissing ovaries", which were multinodulated with yellow serous fluid.
  • Specimens from wedge resection submitted for frozen section showed a benign ovarian cyst.
  • CONCLUSION: With the increasing use of gonadotropins in the management of infertility, ovarian enlargement secondary to hyperstimulation is common.

  • [Title] Expression of extracellular matrix proteins in ovarian serous tumors.
  • The aims of this study were to perform a comprehensive expression analysis of the genes encoding extracellular matrix proteins and to investigate the expression pattern in one of these proteins, syndecan 1, in normal ovarian epithelium as well as benign and malignant ovarian serous tumors.
  • Gene expression of 16 different extracellular matrix proteins was analyzed in ovarian serous tumors based on serial analysis of gene expression database.
  • As compared with normal ovarian surface epithelium, we found overexpression of syndecan 1, collagen type IV alpha 2, elastin microfibril interfase located protein 1, and laminin 5 in ovarian serous carcinomas.
  • Syndecan 1 was selected for further study as it has not been well characterized in ovarian cancer and the syndecan 1 antibody was available for immunohistochemistry.
  • Using a syndecan 1-specific monoclonal antibody, we demonstrated that syndecan 1 was expressed in 30.4% of high-grade serous carcinomas, 29.7% of low-grade carcinomas and serous borderline tumors, but none of benign serous cystadenomas and ovarian surface epithelium.
  • Although both high-grade and low-grade serous carcinomas had a similar percentage of syndecan 1-positive cases, the immunointensity in high-grade carcinoma was significantly higher than that in low-grade carcinomas and serous borderline tumors (P = 0.007).
  • In summary, ovarian carcinomas exhibit up-regulated expression of several extracellular matrix proteins, and syndecan 1 represents a novel tumor-associated marker in ovarian serous carcinomas.

  • [Title] Characterization of humoral responses of ovarian cancer patients: antibody subclasses and antigenic components.
  • OBJECTIVES: Current antigen-based diagnostic assays for ovarian cancers rely on intravasation of specific aberrantly expressed proteins and their achieving detectable steady-state concentrations, resulting in their inability to truly detect small early lesions.
  • In contrast, tumor antigen immunorecognition is observed following initial transformation events.
  • Our objective was to characterize humoral antitumor responses in terms of IgG subclasses generated and tumor antigens recognized.
  • METHODS: For patients with benign and malignant ovarian disease, tumor-reactive IgG subclasses were characterized by Western immunoblotting.
  • RESULTS: Sera from ovarian cancer patients exhibited significantly greater immunoreactivities than either controls or women with benign disease.
  • Two-dimensional electrophoresis revealed 32 stage-linked antigenic differences with 11 in early-stage and 21 in late-stage ovarian cancer.
  • CONCLUSIONS: Owing to the timing and stability of humoral responses, quantitation of IgG subclasses recognizing specific tumor antigens provides superior biomarkers for early cancer identification and allows for differentiation of benign versus malignant ovarian masses and early- and late-stage cancers.

  • [Title] Establishment of subrenal capsule xenografts of primary human ovarian tumors in SCID mice: potential models.
  • OBJECTIVE: To evaluate subrenal capsule xenografting of primary ovarian tumor tissues in mice for development of new ovarian cancer models.
  • METHODS: Pieces (1 x 3 x 3 mm) of ovarian tumor specimens from patients were meticulously grafted under renal capsules of female NOD/SCID mice within 2 h of surgical removal.
  • Tumor types included papillary serous adenocarcinomas, borderline and benign mucinous cystadenomas, granulosa cell tumors, a serous borderline tumor and a grade 3 mixed surface epithelial tumor of transitional and undifferentiated types.
  • RESULTS: Tumor tissue engraftment rate was > 95%.
  • CONCLUSIONS: Subrenal capsule xenografts of primary human ovarian tumors in SCID mice can retain major histopathological and immunohistochemical characteristics of the original tissues.
  • The achievable, consistently high engraftment rate allows use of such xenografts as tools for studying a wide range of ovarian tumors, including granulosa cell tumors and benign, borderline, and malignant surface epithelial neoplasms.
  • Potential applications include preclinical testing of patients' tumor responses to various chemotherapeutic regimens, evaluation of novel therapeutic agents, analysis of tumor progression at cellular and molecular levels, and identification of new therapeutic targets.

  • [Title] Human epididymis protein 4 (HE4) is a secreted glycoprotein that is overexpressed by serous and endometrioid ovarian carcinomas.
  • Among the genes most commonly identified in gene expression profiles of epithelial ovarian carcinomas (EOC) is the gene for human epididymis protein 4 (HE4).
  • To ascertain its clinical utility, we did a comprehensive assessment of HE4 protein expression in benign and malignant ovarian and nonovarian tissues by immunohistochemistry.
  • Its expression in tumors was restricted to certain histologic subtype: 93% of serous and 100% of endometrioid EOCs expressed HE4, whereas only 50% and 0% of clear cell carcinomas and mucinous tumors, respectively, were positive.
  • Using reverse transcription-PCR, we identified ovarian cancer cell lines that endogenously overexpress HE4.
  • Therefore, HE4 is a secreted glycoprotein that is overexpressed by serous and endometrioid EOCs.

  • [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] [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] Validation and characterization of human kallikrein 11 as a serum marker for diagnosis of ovarian carcinoma.
  • PURPOSE: The serum tumor marker CA 125 is elevated in most clinically advanced ovarian carcinomas, and currently, one of the most promising early detection strategies for ovarian cancer uses CA 125 level in conjunction with imaging.
  • However, CA 125 is elevated in only 50% of early-stage ovarian cancer and is often elevated in women with benign ovarian tumors and other gynecologic diseases.
  • The human kallikrein 11 (hK11) marker has been reported to have favorable predictive value for ovarian cancer, although, by itself, it may be inferior to CA 125.
  • CA 125, hK11, and the composite marker were evaluated for their performance in identifying ovarian cancer and for temporal stability.
  • RESULTS: hK11 significantly distinguished ovarian cancer cases from healthy controls and is less sensitive to benign ovarian disease than is CA 125.
  • CONCLUSION: We conclude that hK11 is a valuable new biomarker for ovarian cancer and its temporal stability implies that it may do even better when used in a longitudinal screening program for early detection.

  • [Title] Plexin-B1 silencing inhibits ovarian cancer cell migration and invasion.
  • However, whether or not Plexin-B1 expression is involved in human ovarian tumors remains unclear.
  • In the present study, Plexin-B1 expression was explored in benign and malignant human ovarian tumor tissues.
  • In addition, the impact of Plexin-B1 expression on ovarian cancer cell proliferation, migration and invasion were investigated in vitro.
  • METHODS: Plexin-B1 expression was analyzed in normal and benign ovarian tissues and serous ovarian tumors (both borderline and malignant) by immunohistochemical staining, as well as in four human ovarian cancer cell lines (A2780, C13*, SKOV3, and OV2008) by RT-PCR and western blot analyses.
  • RESULTS: Expression levels of Plexin-B1 protein were significantly higher in serous ovarian carcinomas than in normal ovaries or benign ovarian neoplasms, and in the former, Plexin-B1 expression was positively correlated with lymphatic metastasis, and the membrane and cytoplasm of cancer cells stained positively.
  • SKOV3 cells displayed the highest Plexin-B1 expression at both the mRNA and protein levels among the four tested human ovarian cancer cell lines and was selected as a cell model for further in vitro experiments.
  • CONCLUSION: Plexin-B1 expression correlates with malignant phenotypes of serous ovarian tumors, probably via phosphorylation of AKT at Ser473, suggesting that Plexin-B1 might be a useful biomarker and/or a novel therapeutic target.

  • [Title] Comparative proteomics of ovarian epithelial tumors.
  • We analyzed 12 ovarian epithelial tumors using 2D PAGE-based comparative proteomics to construct intra- and inter-tumoral distance map trees and to discover surrogate biomarkers indicative of an ovarian tumor.
  • The analysis was performed after laser microdissection of 12 fresh-frozen tissue samples, including 4 serous, 5 mucinous, and 3 endometrioid tumors, with correlation with their histopathological characteristics.
  • Ovarian epithelial tumors and normal tissues showed an apparent separation on the distance map tree.
  • Mucinous carcinomas were closest to the normal group, whereas serous carcinomas were located furthest from the normal group.
  • The benign-looking cysts adjacent to the intraepithelial carcinoma (IEC) showed an expression pattern identical to that of the IEC area.
  • The extent of change on the lineages leading to the mucinous and serous carcinoma was 1.98-fold different.
  • The overall gene expression profiles of serous or endometrioid carcinomas appeared to be less affected by grade or stage than by histologic type.
  • The potential candidate biomarkers screened in ovarian tumors and found to be significantly up-regulated in comparison to normal tissues were as follows: NM23, annexin-1, protein phosphatase-1, ferritin light chain, proteasome alpha-6, and NAGK (N-acetyl glucosamine kinase).
  • In conclusion, ovarian mucinous tumors are distinct from other ovarian epithelial tumors.

  • [Title] Intraoperative assessment of ovarian tumors: a 5-year review with assessment of discrepant diagnostic cases.
  • Frozen section is often requested in the intraoperative assessment of patients, presenting with ovarian masses, to provide guidance for appropriate surgical management.
  • To assess the accuracy of frozen section and identify causes of diagnostic error, we reviewed 914 consecutive ovarian frozen sections performed over a 5-year period in 2 laboratories; one of which provides a general surgical pathology service and, the other, a specialist gynecologic pathology service.
  • The series included 552 benign lesions (60.4%), 96 borderline (atypical proliferating) epithelial tumors (10.5%), and 266 malignancies (29.1%).
  • Underdiagnosis of tumor type accounted for 32 of 43 discrepant cases and was most frequent in borderline mucinous tumors.
  • The most common cause of overdiagnosis was the misinterpretation of serous cystadenofibroma as borderline serous tumor.
  • This study confirms that ovarian frozen section is a generally reliable technique, but there are problematic areas, particularly involving the assessment of borderline tumors.
