Popis: We conducted a phase II study to evaluate the efficacy and safety of a triplet regimen of docetaxel, cisplatin, and S-1 in patients with unresectable or recurrent gastric cancer.Docetaxel (40 mg/m(2)) and cisplatin (70 or 60 mg/m(2)) were given on day 1 of a 28-day cycle. S-1 (40 mg/m(2)) was given twice daily on days 1-14. Treatment with this regimen was continued for a maximum of 6 cycles. Subsequently, patients with no disease progression received a combination of docetaxel and S-1.Fifty-nine patients were enrolled. The median number of administered cycles was 8 (range, 1-25). Because some patients had serious myelosuppression and renal dysfunction with 70 mg/m(2) of cisplatin, dose of cisplatin was reduced to 60 mg/m(2) after 19 patients had been treated. Common severe toxic effects of grade 3 or 4 were leukocytopenia (44%), neutropenia (72%), anemia (15%), and febrile neutropenia (14%). The overall response rate of this group was 81% (95% confidence interval (CI), 71-91%). The median overall survival and progression-free survival were 18.5 (95% CI, 15.6-21.5) and 8.7 (95% CI, 6.7-10.7) months, respectively.Triplet of docetaxel, cisplatin, and S-1 is a well-tolerated and highly active regimen for advanced or recurrent gastric cancer. A 60 mg/m(2) of cisplatin is as effective as 70 mg/m(2) of cisplatin.
