Second-line chemotherapy with paclitaxel, cisplatin and gemcitabine in pre-treated sensitive cisplatin-based patients with advanced non-small cell lung cancer.

Background: To investigate the safety and effectiveness of the combination of paclitaxel, cisplatin and gemcitabine as second-line in patients with advanced non-small cell lung cancer (NSCLC) sensitive to first-line cisplatin-based chemotherapy.

Patients And Methods: From June 1997 to December 1998, 26 patients with stage IIIB or IV NSCLC received paclitaxel 125 mg/m2, as a one-hour infusion, followed by cisplatin 50 mg/m2 and gemcitabine 1000 mg/m2, intravenously, on day 1 and 8, every 3 weeks. Twenty-three patients were male; the median age was 59 years (range 44-70); The Eastern Cooperative Oncology Group performance status was 0 to 1 in 88% of patients; 16 patients had stage IV disease and 7 patients had 3 or more sites of disease. The predominant histology was adenocarcinoma in 14 patients. Prior treatment involved cisplatin plus vinorelbine in 14 patients and cisplatin plus mitomycin C plus vindesine in 12 cases.

Results: Seven (27%; exact 95% confidence limits: 11.6-47.8%) patients achieved a partial response to treatment whilst 7 (27%) had stable disease. The median duration of response was 22 weeks (range, 18 to 34 weeks). The median overall survival was 24 weeks (range, 8 to 36 weeks). The main toxicities were: grade 3-4 neutropenia in 9 (34%) patients; grade 2-3 peripheral neuropathy in 10 (38%); and grade 2-3 asthenia in 15 (57%) cases.

Conclusion: The paclitaxel, cisplatin and gemcitabine combination is active as a second-line regimen in patients with advanced NSCLC, but with mild toxicity. It seems suitable for patients with advanced NSCLC as a first-line treatment.
