BACKGROUND: It is unknown whether a history of breast cancer (BC) affects the outcome of BRCA1/2-associated epithelial ovarian cancer (EOC). This was investigated in the current analysis. METHODS: We included 386 BRCA1/2-associated EOC patients diagnosed between 1980 and 2015. Progression-free survival (PFS), progression-free interval (PFI), overall survival (OS) and ovarian cancer-specific survival (OCSS) were compared between EOC patients with and without previous BC...

PURPOSE: The metabolism of olaparib, a potent inhibitor of poly(ADP-ribose) polymerase (PARP) with demonstrated efficacy in patients with BRCA-mutated ovarian cancer, is mediated by cytochrome P450 (CYP) enzymes (predominantly CYP3A4/5). We assessed the potential of a CYP3A4 inhibitor (itraconazole) and inducer (rifampin) to alter the pharmacokinetic (PK) profile of olaparib following single oral tablet doses. METHODS: Two Phase I, open-label, non-randomized trials were conducted in patients with advanced solid tumors...

Poly(ADP-ribose) polymerase (PARP) inhibitors cause targeted tumour cell death in homologous recombination (HR)-deficient cancers, including BRCA-mutated tumours, by exploiting synthetic lethality. PARP inhibitors are being evaluated in late-stage clinical trials of ovarian cancer (OC). Recently, olaparib was the first PARP inhibitor approved in the European Union and United States for the treatment of advanced BRCA-mutated OC. This paper reviews the role of BRCA mutations for tumorigenesis and PARP inhibitor sensitivity, and summarises the clinical development of PARP inhibitors for the treatment of patients diagnosed with OC...

Background Niraparib is an oral poly(adenosine diphosphate [ADP]-ribose) polymerase (PARP) 1/2 inhibitor that has shown clinical activity in patients with ovarian cancer. We sought to evaluate the efficacy of niraparib versus placebo as maintenance treatment for patients with platinum-sensitive, recurrent ovarian cancer. Methods In this randomized, double-blind, phase 3 trial, patients were categorized according to the presence or absence of a germline BRCA mutation (gBRCA cohort and non-gBRCA cohort) and the type of non-gBRCA mutation and were randomly assigned in a 2:1 ratio to receive niraparib (300 mg) or placebo once daily...

ABSTRACTRecent advances in our understanding of the molecular biology of epithelial ovarian cancer have led to the development of a number of targeted therapies, including poly-ADP-ribose polymerase (PARP) inhibitors. PARP inhibitors are a novel class of therapeutic agents that target tumors with deficiencies in the homologous recombination DNA repair pathway. Early studies have shown significant efficacy for PARP inhibitors in patients with germline BRCA1/2 mutations. It has become evident that BRCA wild-type patients with other defects in the homologous recombination repair pathway benefit from this therapeutic approach...

Trabectedin is a marine-derived product that was originally isolated from the Caribbean sea squirt Ecteinascidia turbinata and the first anticancer marine drug to be approved by the European Union. It is currently used as a single agent for the treatment of patients with soft tissue sarcoma after failure of anthracyclines and ifosfamide, or for those patients who are unsuited to receive these agents, and in patients with relapsed, platinum-sensitive ovarian cancer in combination with pegylated liposomal doxorubicin...

There is no consensus on the syntheses concerning the impact of BRCA mutation on ovarian cancer survival. A systematic review and meta-analysis of observational studies was conducted that evaluated the impact of BRCA mutations on the survival outcomes of patients with ovarian cancer. The primary outcome measure was overall survival (OS) and secondary outcome was progression-free survival (PFS). We presented data with hazard ratios (HRs) and 95% confidence interval (CI) and pooled them using the random-effects models...

Poly(adenosine diphosphate-ribose) polymerase (PARP) inhibitors have shown clinical activity in epithelial ovarian cancer, leading both the US Food and Drug Administration (FDA) and the European Medicines Agency to approve olaparib for tumors characterized by BRCA1 and BRCA2 mutations. However, it is becoming increasingly evident that tumors that share molecular features with BRCA-mutant tumors-a concept known as BRCAness-also may exhibit defective homologous recombination DNA repair, and therefore will respond to PARP inhibition...

OBJECTIVE: Most BRCA1/2 carriers do not undergo risk-reducing salpingo-oophorectomy (RRSO) by the recommended age. This study aimed to find the incidence of precursor lesions and cancer after RRSO. METHODS: We retrospectively reviewed breast cancer patients identified as BRCA mutation carriers who underwent RRSO at Asan Medical Center, Seoul, Korea, from 2010 to 2014. From 2013, all cases were examined according to the Sectioning and Extensively Examining the Fimbria (SEE/FIM) protocol and underwent immunohistochemically staining...

PURPOSE: Our preclinical studies showed the PARP inhibitor, olaparib prior to carboplatin attenuated carboplatin cytotoxicity. We evaluated sequence-specific pharmacokinetic/pharmacodynamic (PK/PD) effects, safety and activity of the combination. PATIENTS AND METHODS: Eligible patients had metastatic or recurrent women's cancer. Olaparib tablets were introduced (100 or 200mg bid, days1-7) in a 3+3 dose escalation with carboplatin AUC4 or 5 q21 days, up to eight cycles, followed by olaparib maintenance...

BACKGROUND: Mutations in BRCA1 or BRCA2 genes results in an elevated risk for developing both breast and ovarian cancers over the lifetime of affected carriers. General surgeons may be faced with questions about surgical risk reduction and survival benefit of prophylactic surgery. METHODS: A systematic literature review was performed using the electronic databases PubMed, OVID MEDLINE, and Scopus comparing prophylactic surgery vs observation with respect to breast and ovarian cancer risk reduction and mortality in BRCA mutation carriers...

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...

BACKGROUND: Despite standard treatment for epithelial ovarian cancer (EOC), that involves cytoreductive surgery followed by platinum-based chemotherapy, and initial high response rates to these, up to 80 % of patients experience relapses with a median progression-free survival of 12-18 months. There remains an urgent need for novel targeted therapies to improve clinical outcomes in ovarian cancer. Of the many targeted therapies currently under evaluation, the most promising strategies developed thus far are antiangiogenic agents and Poly(ADP-ribose) polymerase (PARP) inhibitors...

As next generation sequencing (NGS) increases access to human genetic variation, the challenge of determining clinical significance of variants becomes ever more acute. Germline variants in the BRCA1 and BRCA2 genes can confer substantial lifetime risk of breast and ovarian cancer. Assessment of variant pathogenicity is a critical part of clinical genetic testing for these genes. A database of clinical observations of BRCA variants is a critical resource in that process. This paper describes BRCA Share™, a database created by a unique international alliance of academic centers and commercial testing laboratories...

BACKGROUND: In patients with platinum-sensitive recurrent serous ovarian cancer, maintenance monotherapy with the PARP inhibitor olaparib significantly improves progression-free survival versus placebo. We assessed the effect of maintenance olaparib on overall survival in patients with platinum-sensitive recurrent serous ovarian cancer, including those with BRCA1 and BRCA2 mutations (BRCAm). METHODS: In this randomised, placebo-controlled, double-blind, phase 2 trial involving 82 sites across 16 countries, patients with platinum-sensitive recurrent serous ovarian cancer who had received two or more courses of platinum-based chemotherapy and had responded to their latest regimen were randomly assigned (1:1) using a computer-generated sequence to receive oral maintenance olaparib (as capsules; 400 mg twice a day) or a matching placebo by an interactive voice response system...

Guideline-concordant cancer care is a priority within the Department of Veterans Affairs (VA). In 2009, the VA expanded its capacity to treat breast cancer patients within VA medical centers (VAMCs). We sought to determine whether male and female Veterans diagnosed with breast cancer received BRCA testing as recommended by the National Comprehensive Cancer Network (NCCN) guidelines on Genetic/Familial High-Risk Assessment in Breast and Ovarian Cancer (v. 1.2010-1.2012). Using the 2011-2012 VA Central Cancer Registry and BRCA test orders from Myriad Genetics, we conducted a retrospective study...

BACKGROUND: Women considering risk reduction surgery after a diagnosis of breast/ovarian cancer and/or inherited cancer gene mutation face difficult decisions. The safety of combined breast and gynecologic surgery has not been well studied; therefore, we evaluated the outcomes for patients who have undergone coordinated multispecialty surgery. METHODS: We conducted a retrospective review of patients undergoing simultaneous breast and gynecologic surgery for newly or previously diagnosed breast cancer and/or an inherited cancer gene mutation during the same anesthetic at a single institution from 1999 to 2013...

OBJECTIVE: Most molecular analyses of high-grade serous ovarian, peritoneal and fallopian tube carcinomas (HGSC) require ≥70% tumor (neoplastic) cell nuclei. We characterized the distribution of the percentage of neoplastic nuclei (PNN) in a large cohort of HGSC and correlated PNN with clinical outcomes to determine the fraction of cases outside this range and whether this cut-off introduces selection bias. METHODS: Subjects were prospectively enrolled and normal and neoplastic tissues were snap-frozen...
