Ovarian cancer accounts for only 3% of all cancers in women but is the most lethal gynaecologic malignancy. Low-grade and high-grade ovarian serous carcinomas (OSCs) represent two different diseases with different prognosis, approaches to detection and treatment. We assessed correlation between, MAPK, topoIIα, E-cadherin immunoexpression and clinicopathological features with overall survival (OS) in OSCs. The study included 81 patients undergoing surgery between January 1995 and December 2005.Formalin fixed paraffin embedded tumour sections were reviewed and examined immunohistochemically using antibodies against MAPK, topoIIα and E-cadherin...

BACKGROUND: Tumor-infiltrating leukocytes can either limit cancer growth or facilitate its spread. Diagnostic strategies that comprehensively assess the functional complexity of tumor immune infiltrates could have wide-reaching clinical value. In previous work we identified distinct immune gene signatures in breast tumors that reflect the relative abundance of infiltrating immune cells and exhibited significant associations with patient outcomes. Here we hypothesized that immune gene signatures agnostic to tumor type can be identified by de novo discovery of gene clusters enriched for immunological functions and possessing internal correlation structure conserved across solid tumors from different anatomic sites...

Antibody-drug conjugates (ADC) use monoclonal antibodies (mAb) as vehicles to deliver potent cytotoxic drugs selectively to tumor cells expressing the target. Molecular imaging with zirconium-89 ((89)Zr)-labeled mAbs recapitulates similar targeting biology and might help predict the efficacy of these ADCs. An anti-mesothelin antibody (AMA, MMOT0530A) was used to make comparisons between its efficacy as an ADC and its tumor uptake as measured by (89)Zr immunoPET imaging. Mesothelin-targeted tumor growth inhibition by monomethyl auristatin E (MMAE), ADC AMA-MMAE (DMOT4039A), was measured in mice bearing xenografts of ovarian cancer OVCAR-3×2...

The aim of this study was to clarify the clinical role of CD44 expression in ovarian serous cancer, and its relation to clinicopathologic prognostic factors, disease free survival and overall survival (OS). Immunohistochemical staining for CD44 was performed on 81 formalin-fixed, paraffin-embedded tumor sections. CD44 expression was found in 43% of ovarian carcinoma samples. Correlations between categorical variables were studied using the χ and the Mann-Whitney U test. For survival analysis, the Kaplan-Meier method, the log-rank test and the Cox proportional hazard regression model were used...

BACKGROUND: Epithelial ovarian cancer continues to have the highest case-fatality ratio of all gynecologic cancers, in spite of ongoing advances in risk-assessment, genomics, tumor biology, cytoreductive surgery, chemotherapy, and molecular-targeted interventions. Primary treatment options for advanced-stage disease not only should reflect current best standards, but also need to be tailored for individual patients, with consideration of local resources. METHODS: Formulation of recommendations for optimal primary therapy based on a selective review of data from completed randomized trials, analysis of ongoing trials, and integration with current tumor biology, within the context of individualized clinical care...

With the approval of olaparib as monotherapy treatment in platinum-sensitive, relapsed high-grade serous ovarian cancer by the European Medical Agency (EMA), comprehensive genotyping of BRCA1 and BRCA2 in tumor tissue has become a mandatory pre-therapeutic test. This requires significant advances in routine tumor test methodologies due to the large size of both genes and the lack of mutational hot spots. Classical focused screening approaches, like Sanger sequencing, do not allow for a sensitive, rapid, and economic analysis of tumor tissue...

OBJECTIVE: With the 2013 International Federation of Gynecology and Obstetrics (FIGO) staging for ovarian, fallopian tube, and primary peritoneal cancer, the number of substages changed from 10 to 14. Any classification of a malignancy should easily assign patients to prognostic groups, refer patients to individualized treatments, and allow benchmarking and comparison of patients and results between centers. The stage should reflect survival in particular. The objective of the study was to validate these requirements of the revised FIGO staging on a high number of ovarian cancer patients...
