BRCA mutation testing in determining breast cancer therapy.

ABSTRACT: BRCA mutation-associated breast cancer differs from sporadic breast cancer with regard to future cancer risks and sensitivity to systemic therapies. Now that rapid genetic testing for BRCA1 and BRCA2 mutations is available at the time of breast cancer diagnosis, BRCA mutation status can be considered when making treatment and prevention decisions for BRCA mutation carriers with breast cancer. This article reviews surgical options for management of affected BRCA mutation carriers with emphasis on the risks of ipsilateral recurrence and contralateral breast cancer. The roles of breast-conserving surgery, prophylactic mastectomy, and oophorectomy are reviewed. In addition, the sensitivity of BRCA mutation-associated breast cancer to endocrine therapy, platinum chemotherapy, and poly (ADP-ribose) polymerase inhibitors is reviewed.
