UFT plus cisplatin in advanced non-small-cell lung cancer: interim analysis of 67 patients.
A single-institution phase II study indicated that combination chemotherapy using UFT (tegafur and uracil) plus cisplatin (Platinol) in patients with non-small-cell lung cancer was active with less host toxicity than other cisplatin-based therapies. To confirm these observations, the Japan JFT Lung Cancer Study Group conducted a multi-institutional phase II trial. The number of patients planned for this trial is 110. Eligibility includes previously untreated stage IIIB or IV non-small-cell lung cancer and a good performance status. UFT 400 mg/m2 in two divided doses is administered orally on days 1 through 14, and cisplatin 80 mg/m2 is injected IV on day 8. This treatment is repeated every 3 or 4 weeks. Between April 1995 and May 1996, 67 patients were enrolled, and all 67 were considered eligible for an interim analysis performed in October 1996. Among 63 patients evaluable for response, there was an overall response rate of 30% (95% confidence interval, 19% to 41%), with one complete response and 18 partial responses. With a median follow-up duration of 44 weeks, the median survival time was 32 weeks and the 1-year survival rate was 25%. Grade 3 leukopenia occurred in only 1 of 67 patients (1.5%), and there was no thrombocytopenia of grade 3 or greater. Vomiting, the most common nonhematologic toxicity observed, reached grade 3 or 4 in only 6 patients (9%). This interim analysis seems to support the observations of the previous single-institution phase II trial.
