With the discovery of the BRCA1 gene and other genetic mutations associated with breast cancer, it has been established that hereditary mutations account for up to 5% of patients presenting with breast cancer. We performed a systematic review of English Language Literature to determine the role of BRCA1 and BRCA2 gene mutations in African breast cancer patients. PUBMED and AJOL database were se...

Abstract BACKGROUND Despite progress in the treatment of brain metastasis (BrM) for HER2+ breast cancer (BC), outcomes patients with HER2-negative BC BrM remain poor. Current standard care consists surgery and/or radiotherapy followed by systemic therapy. Preclinical studies show inhibitors poly(ADP-ribose) polymerase (PARP) are effective together as DNA damage response inhibitors. Triple-negat...

BRCA germline mutations are the most common predisposing factor in familial breast-ovarian cancer syndrome families. However, many screened patients are identified as harboring BRCA variants of uncertain significance (VUS), rather than carrying deleterious germline mutations [Calo et al.: Cancers 2010; 2:1644-1660]. While such VUSs are typically reclassified as benign polymorphisms, this may oc...

Evidence shows that Black women diagnosed with breast cancer are substantially less likely to undergo BRCA testing and other multipanel genetic testing compared to White women, despite having a higher incidence of early-age onset breast cancer and triple-negative breast cancer (TNBC). Our study identifies predictors of BRCA testing among Black women treated for breast cancer and examines differ...

The aim of this study was to detect the expression of BRCA-1 and BAG-1 in Triple Negative Breast Cancer (TNBC), and analyse the correlation between protein expression and sensitivity to Platinumbased Chemotherapy (PbC). Malignant tissues from 72 TNBC patients who were treated according to the NP and GP programs; then, the relationships between BRCA-1 and BAG-1 protein expression and the surviva...

Screening for BRCA 1 and BRCA 2 mutations has long moved from the research lab to the clinic as a routine clinical genetic testing. BRCA molecular alteration pattern varies among ethnic groups which makes it already a less straightforward process to select the appropriate mutations for routine genetic testing on the basis of known clinical significance. The present report comprises an in depth ...

BACKGROUND Mutations in the BRCA1 and BRCA2 genes are associated with increased risk of breast, ovarian, and several other cancers. The purpose of the present study was to evaluate the incidence of cancer in first- and second-degree relatives of BRCA mutation carriers compared with the general population. MATERIALS AND METHODS A total of 1,086 pedigrees of BRCA mutation carriers was obtained ...
