Whether adding carboplatin to standard neoadjuvant chemotherapy improves survival inBRCA1/2‐mutated triple‐negative breast cancer (TNBC) is unknown. In this retrospective study, we aimed to explore the efficacy of anthracycline‐taxane (A‐T)‐based or anthracycline‐taxane/carboplatin (A‐TP)‐based neoadjuvant chemotherapy inBRCA1/2‐mutated TNBC. A total of 1585 operable primary breast cancer patients were treated with either neoadjuvant A‐T (n = 886) or A‐TP regimen (n = 699).BRCA1andBRCA2germline mutations were determined in all subjects. Pathological complete response (pCR), recurrence‐free survival (RFS), distant recurrence‐free survival (DRFS) and overall survival (OS) were estimated. Of the entire cohort, 102 patients (6.4%) carried a pathogenicBRCA1/2germline mutation. After a median follow‐up of 81 months, no significant differences in survival between the A‐T and A‐TP arms were found in the entire cohort. However, among 288 TNBC patients,BRCA1/2mutation carriers had significantly better survival when treated with the A‐TP regimen than with the A‐T regimen (5‐year RFS: 82.6% vs 47.9%;P= .024; 5‐year DRFS: 88.5% vs 46.9%;P= .010; 5‐year OS: 88.2% vs 49.9%;P= .036). Multivariate analyses revealed that the A‐TP regimen was a significantly favourable factor for RFS and DRFS and showed a trend towards better OS when compared with the A‐T regimen inBRCA1/2‐mutated TNBC (RFS: adjusted hazard ratio [HR], 0.24; 95% confidence interval [CI], 0.06‐0.91,P= .035; DRFS: HR, 0.17; 95% CI, 0.03‐0.80;P= .025; OS: HR, 0.29; 95% CI, 0.06‐1.49;P= .14). Our study suggested thatBRCA1/2‐mutated TNBC patients gain a survival benefit when carboplatin is added to standard A‐T‐based neoadjuvant chemotherapy.
