OBJECTIVES: The current gold-standard for the first-line treatment in IIIb/IV stages of epithelial ovarian cancer (EOC) is the combination of carboplatin and paclitaxel plus bevacizumab in some countries. In the era of personalized medicine, there is still uncertainty on the impact of several molecularly targeted agents, which have been investigated for the management of this disease. To shed light on the actual role of targeted therapy in EOC, a systematic review and meta-analysis was performed...

Poly(ADP-ribose) polymerase (PARP) inhibitors have proven to be successful agents in inducing synthetic lethality in several malignancies. Several PARP inhibitors have reached clinical trial testing for treatment in different cancers, and, recently, Olaparib (AZD2281) has gained both United States Food and Drug Administration (USFDA) and the European Commission (EC) approval for use in BRCA-mutated advanced ovarian cancer treatment. The need to identify biomarkers, their interactions in DNA damage repair pathways, and their potential utility in identifying patients who are candidates for PARP inhibitor treatment is well recognized...

Pregnancy interruption or abortion may be spontaneous or induced for medical, legal, demographic, and personal reasons. Different events that are present during the woman´s gravid period were described, paying attention to the differences in between fertilization and conception. These issues are very important because people or institutions mix these concepts and posit that pregnancy or conception starts at fertilization in opposition to the actual medical and scientific knowledge. In Mexico there are several millions of spontaneous and induced abortions without medical care, responsible for the high maternal-infant mortality rates...

Platinum-based chemotherapies are first-line treatments for ovarian cancer (OC) patients. Although chemotherapy has a high initial response rate, some patients exhibit inherent chemo-resistance. With advancements of molecular and genomic profiling, it is of high interest to identify molecular and genomic signatures predictive of chemo- sensitivity priori to treatment initiation in order to better personalize care decisions. Previous efforts have made use of mRNA expression levels of selected genes responsible for repairing DNA damage, under the hypothesis that chemo efficacy is associated with their proficiency...

Ovarian cancer is the leading cause of death from a gynaecological malignancy in the Western World. To explore if experiences of physical comfort influenced hope and life courage during final diagnosis and early treatment, qualitative research interviews were performed with women undergoing surgery for ovarian cancer. By applying a phenomenological-hermeneutic methodology, the findings were systematically identified, put into meaning-structures, interpreted and critically discussed. The empirical material constituted a main theme concerning "Hope and life courage are created in the interplay between body and mind," where findings dealt with personal reflections and experiences in relation to the subthemes: "Experiencing discomfort," "The impact of care" and "Comfort and hope...

PURPOSE: Among ovarian cancer patients, African American (AA) women experience poorer survival compared to other race/ethnicity groups. This has been attributed to differences in access to health care. EXPERIMENTAL DESIGN: We evaluated racial/ethnic differences in chemotherapy dosing and survival in a cohort study among members of Kaiser Permanente Northern California, and thus with equivalent access to health care. Analyses included epithelial invasive ovarian cancer cases (n=793) receiving adjuvant first-line therapy of carboplatin and paclitaxel with curative intent, with median follow-up of 50 months...

Translational oncology represents a bridge between basic research and clinical practice in cancer medicine. Today, translational research in oncology benefits from an abundance of knowledge resulting from genome-scale studies regarding the molecular pathways involved in tumorigenesis. In this Forum article, we highlight the state of the art of translational oncology in five major cancer types. We illustrate the use of molecular profiling to subtype colorectal cancer for both diagnosis and treatment, and summarize the results of a nationwide screening program for ovarian cancer based on detection of a tumor biomarker in serum...

Genetic testing for hereditary breast and ovarian cancer is increasingly being offered in newly diagnosed breast and ovarian cancer patients. This genetic information may influence treatment decisions. However, there are some concerns that genetic testing offered in an already vulnerable situation might be an extra burden to these women. The aim of this study was to explore the experiences of women who had been offered and accepted genetic testing when newly diagnosed with breast or ovarian cancer. Four semi-structured focus-group interviews were conducted with 17 women recruited from a Norwegian multicenter study...

In this study, we examined the role of the miRNA miR-770-5p in cisplatin chemotherapy resistance in ovarian cancer (OVC) patients. miR-770-5p expression was reduced in platinum-resistant patients. Using a 6.128-fold in expression as the cutoff value, miR-770-5p expression served as a prognostic biomarker and predicted the response to cisplatin treatment and survival among OVC patients. Overexpression of miR-770-5p in vitro reduced survival in chemoresistant cell lines after cisplatin treatment. ERCC2, a target gene of miR-770-5p that participates in the NER system, was negatively regulated by miR-770-5p...

Chemoresistance is the main challenge for the recurrent ovarian cancer therapy and responsible for treatment failure and unfavorable clinical outcome. Understanding mechanisms of chemoresistance in ovarian cancer would help to predict disease progression, develop new therapies and personalize systemic therapy. In the last decade, accumulating evidence demonstrates that epithelial-mesenchymal transition and cancer stem cells play important roles in ovarian cancer chemoresistance and metastasis. Treatment of epithelial-mesenchymal transition and cancer stem cells holds promise for improving current ovarian cancer therapies and prolonging the survival of recurrent ovarian cancer patients in the future...

The traditional model by which an individual was identified as harboring a hereditary susceptibility to cancer was to test for a mutation in a single gene or a finite number of genes associated with a particular syndrome (e.g., BRCA1 and BRCA2 for hereditary breast and ovarian cancer or mismatch repair genes for Lynch syndrome). The decision regarding which gene or genes to test for was based on a review of the patient's personal medical history and their family history. With advances in next-generation DNA sequencing technology, offering simultaneous testing for multiple genes associated with a hereditary susceptibility to cancer is now possible...

The era of big data and precision medicine has led to accumulation of massive datasets of gene expression data and clinical information of patients. For a new patient, we propose that identification of a highly similar reference patient from an existing patient database via similarity matching of both clinical and expression data could be useful for predicting the prognostic risk or therapeutic efficacy.Here, we propose a novel methodology to predict disease/treatment outcome via analysis of the similarity between any pair of patients who are each characterized by a certain set of pre-defined biological variables (biomarkers or clinical features) represented initially as a prognostic binary variable vector (PBVV) and subsequently transformed to a prognostic signature vector (PSV)...

The BRCA1-BRCA2 genes predispose to hereditary breast and ovarian cancer, and the germline and mutational status of these genes defines a target population that can benefit from PARP inhibitor treatments. To respond to the increasing number of BRCA1-BRCA2 tests, it is necessary to shift to high-throughput technologies that are reliable and less time consuming. Different methodological platforms are dedicated to this purpose with different approaches and algorithms for analysis. Our aim was to set up a cost-effective and low time-consuming BRCA1-BRCA2 mutation detection workflow using the Ion Torrent PGM technology...

High-Grade Serous Ovarian Carcinoma (HGSOC) is the predominant histotype of epithelial ovarian cancer (EOC), characterized by advanced stage at diagnosis, frequent TP53 mutation, rapid progression, and high responsiveness to platinum-based-chemotherapy. To date, standard first-line-chemotherapy in advanced EOC includes platinum salts and paclitaxel with or without bevacizumab. The major prognostic factor is the response duration from the end of the platinum-based treatment (platinum-free interval) and about 10-0 % of EOC patients bear a platinum-refractory disease or develop early resistance (platinum-free interval shorter than 6 months)...

OBJECTIVE: To assess the cost-effectiveness of a strategy employing genomic-based tumor testing to guide therapy for platinum-resistant ovarian cancer. METHODS: A decision model was created to compare standard of care (SOC) cytotoxic chemotherapy to a genomic-based treatment strategy. The genomic arm included tumor testing with treatment directed at targets identified. Overall survival was assumed to be similar between strategies; quality of life (QOL) was assumed superior during targeted therapy compared to chemotherapy...
