Abstract

To compare the time-to-treatment failure (TTF), overall survival (OS), overall response rate (ORR), and adverse effects of regimens including nedaplatin- or cisplatin-based chemotherapy for advanced breast cancer (ABC). A total of 171 patients with ABC (admission between July 2008 and July 2013) were retrospectively analyzed. Patients received either nedaplatin 75 mg/m(2) (arm N; n = 85) or cisplatin 75 mg/m(2) (arm C; n = 86) in combination with other second-generation chemotherapeutic drugs, such as paclitaxel 175 mg/m(2), docetaxel 75 mg/m(2), gemcitabine 1.25 g/m(2), and navelbine 25 mg/m(2) every 21 days (nedaplatin, cisplatin, paclitaxel, docetaxel on day 1; gemcitabine, navelbine on days 1 and 8). The primary endpoint was TTF in each arm; secondary endpoints were OS, ORR, and toxicity. In the assessable patient population, in arm N, median TTF and OS was 13.87 months (95% CI: 11.55-16.19) and 31.53 months (95% CI: 28.42-34.64), respectively, with an ORR of 48.2%. In arm C, median TTF and OS was 8.7 months (95% CI: 5.82-11.59) and 24.87 months (95% CI: 18.98-30.75), respectively, with an ORR of 37.2%. The occurrence of grades 3 and 4 hematologic toxicity was more frequent (45.9% vs. 25.6%, p = 0.003) in arm N than in arm ...Continue Reading
