Abstract

Introduction: To conduct a phase II study evaluating the efficacy of rationally sequenced paclitaxel, gemcitabine, and carboplatin in patients with stage IV or select stage IIIB non-small cell lung cancer (NSCLC). Methods: Patients with select stages IIIB (pleural effusion) and IV NSCLC with an ECOG performance status of 0-1 and no prior chemotherapy for their disease were eligible to participate. Treatment was delivered as follows: paclitaxel at 70 mg/m2 followed by gemcitabine at 300 mg/m2 on day 1, with carboplatin (AUC 5) on day 2 of a 28-day cycle. Response was assessed after every two cycles of therapy. The primary endpoint of this trial was response rate, with secondary endpoints of time to progression and 1 year overall survival. Results: Twenty patients were enrolled on protocol, one of whom never received chemotherapy. The median number of cycles delivered was 3 (range 0-8). A partial response rate of 42% (8/19; 95% CI: 20-67%) and a stable disease rate of 11% (2/19; 95% CI: 1-33%) were observed. The median overall survival time was 9.6 months (95% CI: 4.6-16.6), with a 1 year overall survival rate of 42.1% (95% CI: 24.9-71.3%). Eight patients (42%) stopped treatment due to toxicity. Conclusion: Paclitaxel followed by gemcitabine and then carboplatin is an active, albeit complex, regimen in the treatment of patients with advanced NSCLC with insufficient advantage to justify continuation of this regimen.
