Abstract
Purpose
The purpose of the present phase II study was to evaluate both the efficacy and toxicity of the combination of S-1 and docetaxel in previously treated patients with locally advanced or metastatic non-small cell lung cancer.
Methods
Thirty-eight previously treated patients with non-small cell lung cancer were treated with S-1 (80 mg/m2, days 1–14, oral) and docetaxel (40 mg/m2, day 1, intravenous) every 3 weeks.
Results
No complete response was observed, and seven patients had a partial response, yielding an overall response rate of 18.4% (95% CI, 7.7–34.3%). The median overall survival time and 1-year overall survival rate were 16.1 months and 60%, respectively. The median progression-free survival time was 4.4 months. Myelosuppression was the main toxicity with grade 3 or 4 neutropenia and leukopenia in 50 and 21%, respectively. There was no irreversible toxicity in this study.
Conclusions
The combination of S-1 and docetaxel is well tolerable and has substantial activity for patients with locally advanced or metastatic non-small cell lung cancer. A phase III trial comparing docetaxel with or without S-1 would warrant further investigation.
