OBJECTIVE The role of BRCA dysfunction on the prognosis of patients with epithelial ovarian cancer (EOCs) remains controversial. This systematic review tried to assess the role of BRCA dysfunction, including BRCA1/2 germline, somatic mutations, low BRCA1 protein/mRNA expression or BRCA1 promoter methylation, as prognostic factor in EOCs. METHODS Studies were selected for analysis if they prov...
Platinum drugs and PARP inhibitors ("PARPis") are considered to be effective in BRCA-associated cancers with impaired DNA repair. These agents cause stalled and collapsed replication forks and create double-strand breaks effectively in the absence of repair mechanisms, resulting in arrest of the cell cycle and induction of cell death. However, recent studies have shown failure of these chemothe...
Methods: The USPSTF reviewed the evidence on risk assessment, genetic counseling, and genetic testing for potentially harmful BRCA mutations in asymptomatic women with a family history of breast or ovarian cancer but no personal history of cancer or known potentially harmful BRCA mutations in their family. The USPSTF also reviewed interventions aimed at reducing the risk for BRCArelated cancer ...
BACKGROUND The aim of this study was to analyze the occurrence of clinical features characteristic of breast cancer type 1 susceptibility protein (BRCA-1)-dependent tumors in a series of BRCA-1 mutation carriers with laryngeal cancer. PATIENTS AND METHODS The clinical features of five laryngeal cancer patients with BRCA-1 mutations registered in our center were analyzed for: sex, age at diagn...
We disclose the development of a novel series of 2-phenyl-2H-indazole-7-carboxamides as poly(ADP-ribose)polymerase (PARP) 1 and 2 inhibitors. This series was optimized to improve enzyme and cellular activity, and the resulting PARP inhibitors display antiproliferation activities against BRCA-1 and BRCA-2 deficient cancer cells, with high selectivity over BRCA proficient cells. Extrahepatic oxid...
Breast cancer associated with BRCA1 and BRCA2 gene mutations differs from non-BRCA tumors in several respects. We determined whether there was any difference in CCND1 (11q13) and ZNF217 (20q13) gene amplification with respect to BRCA status. Of 40 breast cancer samples examined, 15 and 9 were from BRCA1 and BRCA2 mutation carriers, respectively, and 16 from patients without mutation. Fluorescen...
BACKGROUND BRCAPRO is a risk assessment model to estimate the risk of carrying a BRCA mutation. BRCA mutation carriers are at higher risk of developing breast, ovarian, pancreatic, and prostate cancer. BRCAPRO was developed for women and found to be superior to other risk assessment models. The present study evaluated the validity of BRCAPRO at predicting the risk of male patients carrying a BR...
INTRODUCTION BRCA mutations increase the risk for development of high-grade pelvic serous carcinomas. Tissue biomarkers distinguishing women at high-risk (HR) for ovarian cancer from those at low-risk (LR) may provide insights into tumor initiation pathways. METHODS A prospective study of 47 HR women (40% BRCA carriers) undergoing risk-reducing salpingo-oophorectomy and 48 LR controls undergo...
•Tumor characteristics of 5 cases of ovarian tumor of low malignant potential (LMP) with BRCA mutation were examined.•Young age, BRCA1 mutation, and presence of invasive implants may be characteristics of BRCA carriers with ovarian LMP.
