Purpose. This multicentre phase II trial was conducted in South Africa to evaluate the activity of a combination of vinorelbine, administered in a new schedule, and cisplatin, in chemonaive patients with advanced non-small-cell lung cancer (NSCLC). Patients and Methods. Between September 1995 and December 1996, 35 patients were enrolled. All patients had at least one bidimensionally measurable lesion. Vinorelbine was administered intravenously on day 1 and day 8 at a dose of 30 mg/m2 and cisplatin was administered intravenously on day 1 at a does on 100 mg/m2. The chemotherapy cycle was repeated every three weeks. Results. Of 35 evaluable patients, 14 (40%) achieved a response (one complete response and 13 partial responses). The median time to progression was 6.4 months (range 12-572 days) and the median survival was 15.7 months (range 12-882+ days). One-year survival was 56%. Toxicity was manageable and consisted of nausea and vomiting (grade 3 in 45% of patients) and grade 3-4 neutropenia seen in 13 patients with three patients experiencing grade 3 infection. Other side-effects were mild, including constipation grade 3 in 9.1%. A total of 153 courses were administered with patients receiving a median dose intensity of 81.7% for vinorelbine, while that of cisplatin was 74.1%. Conclusion. The combination of vinorelbine and cisplatin demonstrated substantial activity in terms of objective response and survival with manageable side-effects in patients with advanced NSCLC. These findings confirm the data from previous randomised studies. Further studies are ongoing in order to evaluate the efficacy of this combination in the neoadjuvant and adjuvant setting.
