Objectives
This study was conducted to evaluate the efficacy and safety of S-1 in patients with advanced non-small-cell lung cancer (NSCLC), receiving two or more prior chemotherapy regimens.
Methods
S-1 was administered orally for 14 consecutive days, followed by a 7-day rest period. This treatment course was repeated until disease progression or intolerable toxicity occurred.
Results
From 2010 to 2012, 45 patients were enrolled in this study. Of the 45 patients, 4 patients [8.9 %, 95 % confidence interval (CI) 0.6–17.2 %] exhibited a partial response and 24 patients (53.3 %) exhibited stable disease. The disease control rate was 62.2 % (95 % CI 48.1–76.4 %). Median progression-free survival was 71 days, and median survival time was 205 days. Four patients had grade 3 hematological toxicities, but toxicities of grade 4 were not observed in this study.
Conclusion
Although S-1 monotherapy as third-line treatment or beyond was well tolerated, the response rate for this regimen did not demonstrate sufficient activity for patients with advanced NSCLC.
