Brief Summary in Lay Language

Women from high risk families with mutations in the BRCA1 or BRCA2 gene have a lifetime risk of about 60% for breast cancer and up to 40% for ovarian cancer. There is accumulating evidence from in vitro and retrospective in vivo studies that BRCA-associated breast cancer exhibit preferential treatment response to substances selectively targeting BRCA deficiency. E.g. the efficiency of platin compounds as cross-linkers is based on the induction of DNA double strand breaks (DSBs). The BRCA genes are involved in DSBs that lead to homologous recombination deficiency (HRD) in BRCA-deficient cells. Bifunctional alkylators (e.g. nitrosourea=carmustine/BCNU) have been recently discovered to show a stronger antitumoral activity compared to platin compounds in BRCA-associated carcinomas by creating cross-links. Therefore patients with advanced BRCA-associated breast and ovarian cancer will be treated with Carmustine.
