Methods: Data for individual outpatients treated in our institution were retrospectively pooled to assess the feasibility of an S-1 and highdose cisplatin short hydration regimen (S-1: 80 to 120 mg on Days 1 to 21;cisplatin: 60 mg/m2?on Day 8, every 5 weeks), which included 2250 ml of intravenous fluids and 1000 ml oral hydration. Ten consecutive patients were treated with S-1 and high-dose cisplatin short hydration for unresectable metastatic gastric cancer from July 2011 to May 2012 and were included in the analysis. Results: With a median of 3.5 medication cycles, unscheduled admission occurred in two patients for 5 days each due to paralytic ileus and cerebral infarction. Four patients required dose reduction, in both S-1 and cisplatin in two patients, and in S-1 alone and cisplatin alone in one patient each. Renal function transiently declined after administration of cisplatin, but serum creatinine level and estimated glomerular filtration rate were both improved by the time of the next administration. Conclusion: This study suggests that an S-1 and high-dose cisplatin short hydration strategy for outpatients with unresectable metastatic gastric cancer might be feasible.展开更多

The aim of study was to evaluate the safety and the efficacy of S-1 plus cisplatin doublet chemotherapy with short hydration. Methods: S-1 was administered orally (p.o.) twice daily for the first 3 weeks of a 5-week cycle. Dose of S-1 administered was calculated according to the body surface area. CDDP was given as an intravenous (i.v.) infusion of 60 mg/m2 on day 8 of each cycle. Patients received the total of 1900 ml infusion containing 1000 ml of acetate Ringer’s solution as pre- and post-hydraion. 300 ml of 20% mannitol was administered as a diuretic. Results: 35 patients with unresectable or recurrent gastric cancer were enrolled. The reasons for termination of S-1 + CDDP were as follows: 21 (63.6%) by progressive disease;12 (31.4%) by toxicity. Even though 12 of 35 patients (34.2%) were discontinued S-1 + CDDP chemotherapy, only one patient was discontinued by Grade 2 of increased creatinine. TTF (time to progression) was 174 days (3 - 586 days), and the median of the total number of treatment cycles of S-1 + CDDP was 3.31. Median overall survival, as secondary endpoint, was 518 days. Conclusions: Our study suggested that the short hydration regimen is as safe and efficient as the continuous hydration regimen.展开更多
