PURPOSE: To evaluate docetaxel or vinorelbine, both with trastuzumab, as first-line therapy of human epidermal growth factor receptor 2-positive advanced breast cancer. PATIENTS AND METHODS: Patients naive to chemotherapy for advanced disease were randomly assigned to docetaxel 100 mg/m(2) day 1 or vinorelbine 30 to 35 mg/m(2) on days 1 and 8, both combined with trastuzumab (8-mg/kg loading dose and 6-mg/kg maintenance dose) on day 1 every 3 weeks. The primary end point was time to progression (TTP). RESULTS:A total of 143 patients were randomly allocated to docetaxel, and 141 patients were assigned tovinorelbine. The median TTP for docetaxel and vinorelbine respectively was 12.4 months versus 15.3 months (hazard ratio [HR] = 0.94; 95% CI, 0.71 to 1.25; P = .67), median overall survival was 35.7 months versus 38.8 months (HR = 1.01; 95% CI, 0.71 to 1.42; P = .98), and the 1-year survival rate was 88% in both arms. Median time to treatment failure for study chemotherapy was 5.6 months versus 7.7 months (HR = 0.50; 95% CI, 0.38 to 0.64; P < .0001). The investigator-assessed overall response rate among 241 patients with measurable disease were 59.3% in both arms. More patients in the docetaxel arm discontinued therapy due to toxicity (P < .001). Significantly more treatment-related grade 3 to 4 febrile neutropenia (36.0% v 10.1%), leucopenia (40.3% v 21.0%), infection 25.1% v 13.0%), fever (4.3% v 0%), neuropathy (30.9% v 3.6%), nail changes (7.9% v 0.7%), and edema (6.5% v 0%) were reported with docetaxel. CONCLUSION: The study failed to demonstrate superiority of any drug in terms of efficacy, but the vinorelbine combination had significantly fewer adverse effects and should be considered as an alternative first-line option.
