Abstract
BRCA-associated homologous recombination deficiency (HRD) is present in ~50% of high-grade serous carcinomas (HGSC) and predicts sensitivity to platinum-based therapy. However, there is little understanding of why some patients with BRCA-deficient tumors experience poor outcomes. In a large HGSC cohort (n = 1389) including 282 individuals with pathogenic germline BRCA variants (gBRCApv), residual disease after primary surgery has limited prognostic effect in gBRCApv-carriers compared to non-carriers, and prognostic outcomes differ based on the mutation location within functional domains of the BRCA genes. Multi-omic profiling is performed on 154 tumors, enriched for patients with BRCA-deficient tumors that experienced short overall survival ( ≤ 3 years, n = 42). Patients with BRCA2-deficient HGSC and loss of NF1 survive twice as long as those without NF1 loss, whereas PIK3CA, RAD21 and MYC amplification define BRCA2-deficient HGSC with exceptionally short survival. Patients with BRCA1-deficient HGSC and a more elevated HRD score survive significantly longer. BRCA1-deficient tumors in short survivors have evidence of immunosuppressive c-kit signaling and EMT. Our findings confirm that outcome is not determined by BRCA status alone, but rather a combination of co-occurring genomic alterations, the extent of DNA repair deficiency, and the tumor-immune microenvironment.
