Combination chemotherapy with vindesine-ifosfamide-cisplatin (VIP) in locally advanced unresectable stage III and in stage IV non-small cell lung cancer: A phase II trial

The efficacy and toxicity of a regimen adding ifosfamide to the more classical cisplatin-vindesine combination was studied in patients with advanced non-small cell lung cancer. Sixty-four good performance patients with inoperable stage III or stage IV were treated with VIP: vindesine 3 mg/m(2) days 1 and 8, ifosfamide 1200 mg/m(2) and platinum 30 mg/m(2) days 1, 2 and 3, repeated every 4 weeks, up to a maximum of six cycles. Response rate, clinical data and radiological tests were rigourously reviewed by a panel. Overall response rate was 39% (95% confidence interval, 27%-51%) with three patients achieving a complete response; response rate in stage III was 48%. Median survival was 9 months. Toxicity consisted mainly of bone marrow toxicity and nausea/vomiting, but was manageable. There was no renal toxicity greater than grade 2, four severe infections, but no treatment-related deaths. Conclusion: VIP as mentioned above is very active in good performance patients with advanced non-small cell lung cancer. Its activity, together with its manageable toxicity - without severe renal or pulmonary toxicity - makes it an attractive candidate for induction chemotherapy.
