Homologous Recombination Deficiency in Breast Cancer: A Clinical Review

Abstract excerpt

BRCA1 and BRCA2 germline mutation–associated breast cancers are known to be deficient in the process of homologous recombination and often respond favorably to drugs targeting this important DNA repair pathway. There is emerging evidence that a significant proportion of patients with BRCA1/ BRCA2 wild-type breast cancer are also deficient in homologous recombination, and it is hypothesized that these patients may...
