Abstract

A prospective study was conducted to investigate the efficacy of a combined regimen of gemcitabine and S-1 for the treatment of elderly patients (>70 years) with advanced non‑small cell lung cancer (NSCLC) as a first‑line setting based on the dosage recommended in a previous phase I study. Chemotherapy‑naïve patients with advanced NSCLC received gemcitabine plus S‑1. S‑1 (40 mg/m2) was administered orally twice daily for 14 days while gemcitabine (1,000 mg/m2) was administered on days 1 and 15 of each cycle, and this regimen was repeated every 4 weeks. A total of 20 patients were included in the present study. Of these, 8 patients achieved an overall response rate of 40.0%, and the overall disease control rate was 65.0%. According to the histological type, the response rate in patients with NSCLC and adenocarcinoma was 38.5%, and that for non‑adenocarcinoma was 42.9%. Progression‑free survival and median survival times were 6.4 months and 17.8 months, respectively. Grade 3 or 4 hematological toxicities observed were leukopenia (29%) and neutropenia (24%), while febrile neutropenia was not observed in any patient. The only non‑hematological adverse event observed was grade 3 skin rash (10%). Therefore, the combination of gemcitabine and S‑1 may be a promising and feasible regimen in the first‑line setting for elderly patients with advanced NSCLC.
