title: [Phase II study of S-1, a novel oral fluorouracil, in advanced non-small-cell lung cancer].
abstract: The purpose of this study was to evaluate the efficacy and safety of a novel oral anticancer fluoropyrimidine derivative, S-1, in patients receiving initial chemotherapy for unresectable, advanced non-small-cell lung cancer (NSCLC). Between June 1996 and July 1998, 62 patients with NSCLC who received no previous chemotherapy for advanced disease were enrolled in this study. Fifty nine patients (22 in stage IIIB and 37 in stage IV) were eligible for the evaluation of efficacy and safety. S-1 was orally administered twice daily after meals. Three doses of S-1 were prescribed according to body surface area (BSA), so that they would be approximately equivalent to 80 mg/m2/day. One cycle of S-1 consisted of consecutive administration for 28 days followed by a 2-week rest, and the cycle was repeated up to 4 times. The partial response (PR) rate of the eligible patients was 22.0% (13/59) (95% confidence interval: 12.3-34.7%). Grade 4 neutropenia was observed in one of the 59 patients (1.7%). There were no irreversible, severe or unexpected toxicities. The median survival time (MST) of all of the patients was 10.2 months (95% confidence interval: 7.7-14.5 months), and the one-year survival rate was 41.1%. S-1 was considered to be an active single agent against NSCLC.
