The purpose of this study was to evaluate the efficacy and tolerance of combined irinotecan and vinorelbine in previously treated patients with stage IIIB and IV non-small-cell lung cancer (NSCLC). Thirty-three patients with NSCLC (7 stage IIIB and 26 stage IV) were enrolled.
All had been previously treated with cisplatin, paclitaxel, and gemcitabine as first-line chemotherapy. In addition, 24 patients had received radiotherapy. Irinotecan (300 mg/m(2)) was administered on day 1 and vinorelbine (30 mg/m(2)) on days 1 and 14, every 4 weeks. Partial response was achieved in 3 patients (9%; 95% CI: 2-24%), stable disease (SD) in 13 (39%; 95% CI: 23-58%), whereas 17 patients progressed (51%; 95% CI: 33-69%). Median event-free survival was 10 weeks and median overall survival was 25 weeks. Three patients were event free at the end of the study with a follow-up of 40, 73, and 75 weeks. Toxicity was mild, with leukopenia grade III-IV in 8.6% of cycles. No episodes of diarrhea III-IV were observed. Three patients died early after administration of this combination, one of them in the context of severe leukopenia and thrombocytopenia.
Approximately 50% of patients treated with CPT-11 and vinorelbine in combination show partial response or stable disease with minimal toxicity.
