The aim of this study was to determine the efficacy and toxicity of a biweekly combination of docetaxel and vinorelbine in patients with metastatic breast cancer (MBC) previously treated with anthracyclines. Eligible patients (n = 49) with MBC received vinorelbine, 25 mg/m2, followed by docetaxel, 60 mg/m2. Cycles were repeated every 14 days for a total of 8 planned cycles. Response rate was evaluated every 4 cycles. All 49 patients were evaluable for safety and 44 for efficacy. Vinorelbine plus docetaxel resulted in an overall response rate of 45% (CI 95%: 31-60) with 2 (4%) complete responses and 18 (41%) partial responses. Patients with visceral metastasis achieved a lower response rate than those without (33% versus 60%, p = 0.044). Time to progression was 11.0 months (CI 95%: 8.6-13.5), and median overall survival was 12.7 months (CI 95%: 9.0-16.4). The most common grade III to IV hematologic adverse events was neutropenia (65% of patients). Febrile neutropenia was observed in 9 cycles (3%) and in 7 patients (14%). Grade III to IV nonhematologic toxicity was rare. Biweekly combination of docetaxel and vinorelbine is an effective and well-tolerated regimen in anthracycline-resistant MBC.
