To investigate the relationship between polymorphism in the 3'-untranslated region (3'-UTR) of the thymidylate synthase (TS) gene and sensitivity of gastric cancer to 5-fluorouracil (5-FU)-based chemotherapy, 106 cases of advanced gastric cancer were analyzed. All patients were treated with 5-FU-based chemotherapy; DNA from peripheral blood leukocytes was obtained before therapy. TS 3'-UTR genotypes were detected by PCR-RFLP. Polymorphism in the TS 3'-UTR can be classified into three groups according to the presence or absence of a 6 bp nucleotide fragment: the -6/-6 bp, -6/+6 bp and +6/+6 bp groups. The response rate of the -6/-6 bp and -6/+6 bp groups was found to be significantly higher than the +6/+6 bp group. These results show that the presence of the TS 3'-UTR 6 bp nucleotide fragment can be correlated with the sensitivity of gastric cancer to 5-FU-based chemotherapy, and that the TS 3'-UTR polymorphism profile can be used to guide the choice of 5-FU-based chemotherapy in advanced gastric cancer.
