    Abstract:
    OBJECTIVES: The aim of the present study was to evaluate the efficacy and safety of carboplatin plus paclitaxel versus gemcitabine plus vinorelbine in patients with advanced nonsmall cell lung cancer (NSCLC) and an Eastern Cooperative Oncology Group performance status (PS) of 2. METHODS: Chemotherapy-naive patients with NSCLC of stage IIIB or IV and a PS of 2 were eligible. The patients received 3-week cycles of carboplatin (area under the curve of 6) plus paclitaxel (200 mg/m(2)) on day 1 (CP) or gemcitabine (1000 mg/m(2)) plus vinorelbine (25 mg/m(2)) on days 1 and 8 (GV). The primary end point was 1-year survival rate for selection of the better treatment arm for further study. RESULTS: Of the 89 patients enrolled, 84 were assessable (41 in the CP arm, 43 in the GV arm). The overall response rate, median survival time, and 1-year survival rate were 29.3%, 5.9 months, and 22.0%, respectively, for the CP arm and 20.9%, 6.0 months, and 27.9% for the GV arm. Common toxicities of grade 3 or 4 included neutropenia (67.5% for the CP arm vs. 65.1% for the GV arm), febrile neutropenia (20% vs. 14%), and infection (25.0% vs. 23.2%). The frequency of nausea of grade 3 was greater for the CP arm (17.5% vs. 2.3%), whereas that of anemia of grade 3 or 4 (30.2% vs. 12.5%) or treatment-related death (7.0% vs. 2.4%) was greater for the GV arm. CONCLUSIONS: The 1-year survival rate did not exceed 30% for either doublet chemotherapy. Furthermore, each treatment was associated with a substantial degree of toxicity.
