BACKGROUND: Improving survival in non-small cell lung cancer (NSCLC) will require new strategies or new drugs. Sequential administration of conventional non-cross-resistant cytotoxic drugs offers an opportunity to increase drug diversity while maintaining dose intensity. This Phase II trial was designed to assess the efficacy and feasibility of such a regimen in advanced NSCLC. METHODS: Patients with NSCLC stage IIIB or IV received as first-line treatment four cycles of carboplatin (AUC 5) (day 1) plus gemcitabine 1000 mg/m(2) (days 1 and 8) every 3 weeks. Thereafter, treatment continued with 12 weekly cycles of paclitaxel 80 mg/m(2). RESULTS: In total, 46 patients were included. Median age was 59.6 years (range 41.3-74.3 years) and 93.5 % (n = 43) had Eastern Cooperative Oncology Group performance score of 0 or 1. All but 6 had stage IV disease, and 13 (28.3 %) had squamous cell carcinomas. Thirty-six (78 %) patients completed 4 cycles of carboplatin-gemcitabine and 35 patients received at least 1 cycle of paclitaxel, of whom 16 (46 % of total) patients completed 12 cycles of paclitaxel. The overall objective response rate was 49 %. Sixteen (37 %) patients had a response to carboplatin-gemcitabine, increasing to 21 (49 %) patients after administration of paclitaxel. Of the 13 assessable patients who showed a partial response (PR) on carboplatin-gemcitabine, 12 (92 %) patients showed also a PR on paclitaxel. Of 19 assessable patients with stable disease (SD) on carboplatin-gemcitabine, 4 (21 %) had a PR and 13 (68 %) SD on paclitaxel. Toxicity was moderate: 24 % stopped because of toxicity. CONCLUSION: Sequential chemotherapy with carboplatin-gemcitabine and weekly paclitaxel is active and feasible in advanced NSCLC patients.
