PURPOSE Mutations in BRCA genes are the main cause of hereditary breast cancer in Korea. The aim of this study was to investigate the characteristics of breast cancers involving BRCA1 (BRCA1 group) and BRCA2 (BRCA2 group) mutations. METHODS We retrospectively reviewed the medical records of patients with BRCA1 (BRCA1 group) or BRCA2 (BRCA2 group) mutation positive breast cancer from multiple ...
BRCA and poly-ADP ribose polymerase (PARP) regulate pathways of DNA repair. Due to the accumulation of mutations introduced by error-prone DNA repair, breast and ovarian cancers develop in the setting of BRCA deficiency. A series of recent clinical trials has tested the use of PARP inhibition as a therapeutic strategy to target BRCA-deficient tumors.
Lack of awareness, the stigma of carrying a genetic mutation, and economic factors are barriers to acceptance of BRCA genetic testing or appropriate risk management. We aimed to investigate the influence of Angelina Jolie's announcement of her medical experience and also health insurance reimbursement for BRCA gene testing on practice patterns for hereditary breast and ovarian cancer (HBOC). A ...
Bioactive compounds from edible plants have limited efficacy in treating advanced cancers, but they have potential to increase the efficacy of chemotherapy drugs in a combined treatment. An aqueous extract of berries of Pimenta dioica (Allspice) shows promise as one such candidate for combination therapy or chemoprevention. An aqueous extract of Allspice (AAE) was tested against human breast ca...
Introduction It has been estimated that 19,880 new cases of ovarian cancer had diagnosed in 2022. Most epithelial are sporadic, while 15%–25% cases, there is evidence a familial or inherited component. Approximately 20%–25% high-grade serous carcinoma caused by germline mutations the BRCA1 and BRCA2 genes. However, owing to lack effective early detection methods, women with BRCA recommended und...
PURPOSE Veliparib, a PARP inhibitor, demonstrated clinical activity in combination with oral cyclophosphamide in patients with BRCA-mutant solid tumors in a phase I trial. To define the relative contribution of PARP inhibition to the observed clinical activity, we conducted a randomized phase II trial to determine the response rate of veliparib in combination with cyclophosphamide compared with...
BACKGROUND Germline mutations in the BRCA1 and BRCA2 genes are the most frequent known hereditary causes of familial breast cancer. Little is known about the interaction of age at diagnosis, estrogen receptor (ER) and progesterone receptor (PgR) expression and outcomes in patients with BRCA1 or BRCA2 mutations. METHODS A PubMed search identified publications exploring the association between ...
OBJECTIVES Poly (ADP-ribose) polymerase inhibitors (PARPi) have shown single agent activity against tumors with deficiencies in the DNA repair mechanism homologous recombination including, but not limited to those harboring BRCA mutations. We hypothesized that, in the context of homologous recombination deficiency (HRD), PARPi could have an effect in head and neck cancer (HNC). MATERIALS AND ...
BACKGROUND Germline mutations in the BRCA1 and BRCA2 genes account for 20-25 % of inherited breast cancers and about 10 % of all breast cancer cases. Detection of BRCA mutation carriers can lead to therapeutic interventions such as mastectomy, oophorectomy, hormonal prevention therapy, improved screening, and targeted therapies such as PARP-inhibition. We estimate that African Americans and His...
