Purpose
We evaluated the efficacy and toxicity of biweekly S-1 and docetaxel combination therapy in patients with advanced gastric cancer.
Methods
Patients with histologically proven, unresectable advanced or recurrent gastric cancer, a performance status (PS) of 0–2 and no prior chemotherapy history were eligible for inclusion (n = 45). Patients received a total of 215 treatment courses (median, 4; range, 2–12) of S-1 oral administration twice daily for 1 week followed by a drug-free interval of 1 week. Docetaxel (40 mg/m2) was administered intravenously on days 1 and 15.
Results
We observed 25 partial responses (55.6%) and one complete response (2.2%), resulting in an overall response rate of 57.8%. Twenty-four patients (53.3%) received second-line chemotherapy. Five patients (11.1%) underwent R0 gastrectomy during the course of the study. The median overall survival time was 15.3 months, the median time to progression was 6.9 months, and the median duration of response in 26 patients was 8.0 months. Neutropenia was the most frequently observed (40.4%) haematological toxicity at grades 3 and 4 and leucopenia was the second most common (29.8%). There were no treatment-related deaths.
Conclusions
S-1 plus docetaxel combination therapy in an outpatient setting provided promising activity with acceptable adverse toxicities.
