PURPOSE: This phase II trial first describes the combination chemotherapy of biweekly irinotecan plus S-1 (biweekly IRIS) for pretreated advanced gastric cancer (AGC) patients. METHODS: Patients who had previously been treated with greater than or equal to one regimen were enrolled. They received S-1 35 mg/m(2) twice daily on days 1-14 and irinotecan 150 mg/m(2) on days 1 and 15, every 4 weeks. The primary endpoint was overall survival (OS). RESULTS: Among the 38 patients enrolled, 18 patients were treated as second line, and the remaining 20 patients were enrolled as third- or fourth line. A total of 208 cycles were administered with the median being four cycles (range 1-16). The median OS was 8.7 months [95% confidence interval (CI) 7.5-10.3], and the median progression-free survival was 6.3 months (95% CI 5.3-7.3). Low serum albumin (<3.5 mg/dL) was an independent adverse prognosticator for survival. Overall response rate was 17% (95% CI 4-30%). The major grade 3/4 toxicities were neutropenia (26%) and diarrhea (18%). CONCLUSIONS: Biweekly IRIS showed the moderate activity as salvage treatment in AGC. Considering high neutropenia and gastrointestinal toxicity, patient selection should be warranted; serum albumin may be a predictive factor for treatment decision
