摘要：The purpose of this study was to retrospectively examine the effect of concomitant administration of gastric secretion inhibitors or gastrectomy on the frequency of gastrointestinal toxicity caused by 5-fluorouracil (5-FU) in gastric cancer patients receiving chemotherapy with S-1. In 62 gastric cancer patients treated with S-1 alone, data relating to the occurrence of gastrointestinal toxicity (diarrhea, vomiting, and nausea) and possible contributing factors were retrospectively collected, and logistic regression analysis was performed. Time-to-event data relating to the occurrence of gastrointestinal toxicity were also collected, and the effect of gastric secretion inhibitors on the time-to-event profiles was examined using a log-rank test. Logistic regression analysis suggested that the frequency of gastrointestinal toxicity was significantly reduced by the administration of gastric secretion inhibitors (p=0.01; odds ratio, 0.197; 95% confidence interval (CI), 0.056–0.694) and that gastrointestinal toxicity correlated with the estimated glomerular filtration rate (p=0.04; odds ratio, 0.956; 95% CI, 0.916–0.997). The median time-to-event of gastrointestinal toxicity was 85 d for patients that received gastric secretion inhibitors, which was significantly different from the 42 d for patients that did not receive the inhibitors (p=0.02, log-rank test). No clear effect of gastrectomy was found in the present study. The prophylactic use of gastric secretion inhibitors in gastric cancer patients treated with S-1 may decrease and delay the occurrence of gastrointestinal toxicity.
