Management of early breast cancer in patients bearing germline BRCA mutations.

Women diagnosed with breast cancers (BCs) that harbor BRCA1/2 mutations have an increased lifetime risk of a second BC and ovarian cancer. They may benefit from risk-reducing surgical strategies such as mastectomy and salpingo-oophorectomy. In cases of triple negative BC with BRCA mutation, there is some evidence that adding platinum-agents in the neoadjuvant setting improves the pathologic complete response. Lastly, ongoing clinical trials testing the efficacy of PARP inhibitor therapy in tumors with BRCA1/2 mutations will be determinant for future guideline recommendations in selecting best adjuvant treatment options for this specific population. For pre-menopausal patients whose tumors have BRCA mutations and hormone-receptor positive BC, the option of combined bilateral annexectomy and hormonal therapy with aromatase inhibitor can be discussed with high-risk patients. This review summarizes the latest results from clinical trials evaluating treatment and prevention strategies for breast cancers harboring BRCA1/2 mutations and discusses the current management of this patient population.
