Homologous Recombination Deficiency Testing for BRCA-Like Tumors: The Road to Clinical Validation

Abstract excerpt

Germline BRCA mutations result in homologous recombination deficiency (HRD) in hereditary breast and ovarian cancer, as well as several types of sporadic tumors. The HRD phenotype makes these tumors sensitive to DNA double strand break-inducing agents, including poly-(ADP-ribose)-polymerase (PARP) inhibitors. Interestingly, a subgroup of cancers without a BRCA mutation also shows an HRD phenotype. Various methods...
