Abstract

This randomized controlled clinical trial was designed to compare the safety and effectiveness of different sequences of treatment with cisplatin (CDDP) and 5-fluorouracil (5-FU) in patients with unresectable advanced and post-operative recurrent gastric cancer. Patients with unresectable advanced or post-operative recurrent gastric cancer were randomly assigned by a registration center to group A or B. Group A received CDDP (80 mg/m2) as a continuous 2-h intravenous infusion on day 1 and 5-FU (700 mg/m2) as a continuous intravenous infusion on days 2-5. Group B was given 5-FU (700 mg/m2) as a continuous intravenous infusion on days 1-4, followed by CDDP (80 mg/m2) as a continuous 2-h intravenous infusion on day 5. Each course of chemotherapy was repeated every 28 days. A total of 74 patients were enrolled. One patient died accidentally, and 5 could not be evaluated. Response was assessable in 68 patients. The response rate was 31.3% (10/32) in group A as compared with 13.9% (5/36) in group B. Although the response rate was higher in Group A, the difference was not significant (p=0.085). The response rate in patients with diffuse type tumors was significantly lower in group B. There was no difference between the groups in response among patients with intestinal type tumors. The median overall survival was 239 and 174 days and time to progression was 175 and 140 days in group A and group B, respectively. Although there were trends toward longer survival and time to progression in group A, the differences between the groups were not statistically significant. There was also no difference in the type or incidence of adverse reactions. The results of this controlled study indicate that the overall response rate was slightly but not significantly higher in patients who received CDDP before 5-FU. Among patients with diffuse type tumors, the response rate was significantly lower when 5-FU was administered before CDDP. Our results suggest that CDDP should be given before 5-FU in patients with gastric cancer when treated with a combination of CDDP and 5-FU.
