BRCA/ATM germline and Abi/Enz

There was an ASCO piece last year about the potential synergy between germline BRCA-only mutation and Abirateron. This is another article that highlights the same, this time for BRCA/ATM germline and Abi/Enz. Sample size is small, so take it with a grain of salt:

"RESULTS AND LIMITATIONS

Among 172 mCRPC patients included, germline mutations (in any DNA-repair gene) were found in 12% (22/172) of men, and germline BRCA/ATM mutations specifically in 5% (9/172) of men. In unadjusted analyses, outcomes to first-line NHT were better in men with germline BRCA/ATM mutations (vs no mutations) with respect to PSA-PFS (hazard ratio [HR] 0.47; p=0.061), PFS (HR 0.50; p=0.090), and OS (HR 0.28; p=0.059). In propensity score-weighted multivariable analyses, outcomes were superior in men with germline BRCA/ATM mutations with respect to PSA-PFS (HR 0.48, 95% confidence interval [CI] 0.25-0.92; p=0.027), PFS (HR 0.52, 95% CI 0.28-0.98; p=0.044), and OS (HR 0.34, 95% CI 0.12-0.99; p=0.048), but not in men with non-BRCA/ATM germline mutations (all p>0.10). These results require prospective validation, and our conclusions are limited by the small number of patients (n=9) with BRCA/ATM mutations."
