Randomized, Multinational, Phase III Study of Docetaxel Plus Platinum Combinations Versus Vinorelbine Plus Cisplatin for Advanced Non–Small-Cell Lung Cancer: The TAX 326 Study Group

To investigate whether docetaxel plus platinum regimens improve survival and affect quality of life (QoL) in advanced non-small-cell lung cancer (NSCLC) compared with vinorelbine plus cisplatin as first-line chemotherapy. Patients (n = 1,218) with stage IIIB to IV NSCLC were randomly assigned to receive docetaxel 75 mg/m2 and cisplatin 75 mg/m2 every 3 weeks (DC); docetaxel 75 mg/m2 and carboplatin area under the curve of 6 mg/mL * min every 3 weeks (DCb); or vinorelbine 25 mg/m2/wk and cisplatin 100 mg/m2 every 4 weeks (VC). Patients treated with DC had a median survival of 11.3 v 10.1 months for VC-treated patients (P =.044; hazard ratio, 1.183 [97.2% confidence interval, 0.989 to 1.416]). The 2-year survival rate was 21% for DC-treated patients and 14% for VC-treated patients. Overall response rate was 31.6% for DC-treated patients v 24.5% for VC-treated patients (P =.029). Median survival (9.4 v 9.9 months [for VC]; P =.657; hazard ratio, 1.048 [97.2 confidence interval, 0.877 to 1.253]) and response (23.9%) with DCb were similar to those results for VC. Neutropenia, thrombocytopenia, infection, and febrile neutropenia were similar with all three regimens. Grade 3 to 4 anemia, nausea, and vomiting were more common (P
