Popis: The clinical benefit of adding platinum to adjuvant chemotherapy for patients with triple-negative breast cancer (TNBC) has not been well investigated, although it was associated an improved response rate in neoadjuvant setting. We retrospectively analyzed the time to tumor progression (TTP) and overall survival (OS) of patients with resected stage I-III TNBC who were treated with or without cisplatin-containing chemotherapy (CisCT or noCisCT) during 2004 and 2010. Of 129 patients, 25 received CisCT. In univariate analysis, the mean TTP for CisCT and noCisCT was 4.42 and 5.88 years, respectively ( P = .004). The mean OS for CisCT and noCisCT was 6.76 and 9.63 years, respectively ( P = .24). After adjusting for other clinicopathologic factors, only clinical stage II/III disease was independently associated with worse OS. The adjusted hazard ratio for CisCT was 1.48 ( P = .46) and was not statistically significant. In this small retrospective study, adding cisplatin to adjuvant chemotherapy for early TNBC with unknown BRCA mutation status did not benefit OS.
