BACKGROUND: The role of surveillance breast MRI for women with mammographically dense breasts, a personal history of breast cancer (BC), atypical hyperplasia (AH), or lobular carcinoma in situ (LCIS) is unclear. We estimated the performance of annual surveillance MRI in women with a combination of these risk factors. METHODS: We performed a retrospective review of the clinical, radiological, and pathological parameters of women who received annual concurrent surveillance breast MRI and mammography between 04/2013 and 12/2015 and fulfilled all of the following criteria: 1) age <70; 2) prior diagnosis of AH, LCIS or BC; 3) heterogeneously or extremely dense breast(s); and 4) did not qualify for our provincial breast MRI high risk screening program...

Poly (ADP-ribose) polymerase (PARP) inhibitors have attracted much attention as one of the major molecular-targeted therapeutics for inhibiting DNA damage response. The PARP inhibitor, olaparib, has been clinically applied for treating certain recurrent ovarian cancer patients with BRCA1/2 mutations in Europe and the United States. It was also designated on 24 March 2017 as an orphan drug in Japan for similar clinical indications. In this review, we discuss (i) the prevalence of BRCA1/2 mutations in ovarian cancer, (ii) clinical trials of PARP inhibitors in ovarian cancer, (iii) genetic counseling for hereditary breast and ovarian cancer patients, and (iv) non-BRCA genes that may be associated with homologous recombination deficiency...

Treatment of triple negative breast cancer (TNBC) has been a big challenge since it is defined. To date, platinum-based chemotherapy has played a significant role in the treatment of TNBC patients. However, some patients do not respond to platinum salts or gradually develop chemoresistance, resulting in little effect, or even some adverse effects. Here, we review numerous preclinical and clinical investigations to summarize possible mechanisms and potential predictive biomarkers of platinum in TNBC. The homologous recombination deficiency (HRD) resulting from the loss of BRCA function is the main rationale of platinum efficacy in TNBC...

Due to short-lived treatment responses in unresectable disease, pancreatic ductal adenocarcinoma (PDAC) continues to be one of the deadliest cancers. There is availability of new information about germline and sporadic mutations in the deoxyribonucleic acid (DNA) damage repair pathway in PDAC in recent decades and the expectation is that novel targeted therapies will thus be developed. A variety of germline mutations (BRCA2, BRCA1, PALB2, CDKN2A, ATM, TP53 and mismatch repair genes MLH1, MSH2, MSH6) have been reported in these patients with the highest prevalence being BRCA1/2...

Hereditary breast cancer syndromes are associated with an increased risk of breast cancer and constitute a unique patient population, making up approximately 5%-10% of breast cancer cases in the United States. By virtue of the germline mutations that define these syndromes, invasive breast cancers in these patients have unique mechanisms that can be rationally targeted for therapeutic opportunities distinct from standard of care treatments in nongermline mutation associated breast cancers. This review intends to describe existing data on several of the most common hereditary breast cancer syndromes, including BRCA-related breast cancer syndrome, Li-Fraumeni syndrome, Cowden syndrome, Peutz-Jeghers syndrome, and hereditary diffuse gastric cancer syndrome, specifically focusing on rational therapeutics utilized in these distinct patient subgroups and completed or ongoing clinical trials evaluating their efficacy...

Specific alkylators may allow synthetic lethality among patients with germline BRCA1/2-mutations related cancers. The tetrahydroisoquinolone trabectedin administered at 1.3 mg/m(2) as a 3-h intravenous infusion every 3 weeks showed activity in patients with pretreated metastatic breast cancer (MBC) and BRCA germline mutations, but mainly in BRCA2 carriers. Data from a phase II study were retrospectively analyzed to compare the efficacy and safety of this trabectedin dose and schedule in pretreated MBC patients bearing germline BRCA1/2 mutations...

Despite recent advances in the treatment of patients with breast cancer (BrCa), BrCa remains the third leading cause of cancer death for women in the US due to intrinsic or acquired resistance to therapy. Continued understanding of gene expression profiling and genomic sequencing has clarified underlying intratumoral molecular heterogeneity. Recently, the patient-derived xenograft (PDX) models have emerged as a novel tool to address the issues of BrCa genomics and tumor heterogeneity, and to critically transform translational BrCa research in the preclinical setting...

The majority of women evaluated for a clinical concern of possible hereditary breast cancer syndromes have no identified pathogenic variants in genes predisposing them to breast cancer. Non-BRCA1- or BRCA2-related familial breast cancer, also called 'BRCAX', thus comprises a sizeable proportion of familial breast cancer but it is poorly understood. In this study, we reviewed 14 studies on histopathology and molecular studies of BRCAX to determine if there were differences between 'sporadic' breast cancers and compared to cancers arising in women harbouring variants in known cancer predisposition genes...

In breast cancer 1 (BRCA) gene mutation carriers, mastectomy is still the mainstay of treatment for breast cancers due to the increased risk of local recurrence. It is performed as a therapeutic, as well as prophylactic procedure. However, mastectomy with removal of nipple areolar complex (NAC) is associated with adverse cosmetic outcome. NAC sparing mastectomy (NSM), which results in better cosmetic outcome, has been performed in non-BRCA mutation carriers. While studies have shown that NSM is a oncologically safe in sporadic breast cancers, its application in BRCA mutation carriers is still controversial...

Importance: In the United States from 2009 to 2013, the incidence of breast cancer was the highest of any cancer and the death rate was second to that of lung cancer. Approximately 5% to 10% of breast cancers are inheritable. Observations: BRCA1 and BRCA2 germline mutations account for up to 30% of inheritable breast cancers and are the most commonly assessed mutations in patients presenting with early-onset breast cancer, triple-negative breast cancer, bilateral breast cancer, and a family history of breast cancer...

Triple negative breast (TNBC) cancer constitutes a heterogeneous group of disease with histologic and molecular differences. Complete pathologic response to neoadjuvant chemotherapy (NACT) in TNBC is associated with improved outcomes. Efforts have been made in identifying drug combinations that will increase the response rate to preoperative chemotherapy. In this review we present recent studies that have incorporated carboplatin (Cb) in the NACT of TNBC. We discuss the homologous recombination deficiency score and the somatic or germline mutation for BRCA as potential biomarkers for future selection of patients that could benefit from the addition of Cb to NACT...
