摘要: We evaluated DNA polymorphisms in the thymidylate synthase (TS) and 5,10-methylene-tetrahydrofolate reductase (MTHFR) genes for an association with response survival locally advanced gastric cancer treated 5-FU based preoperative chemotherapy (CTx). of 238 patients (CTx-group: total n 5 135, completely resected (R0) 102; without CTx: R0 103) was isolated from blood or nontumorous tissues. In CTx-group, genotyping tandem repeat G/C polymorphism triple promoter region TS gene C677T MTHFR performed. None genotypes were associated histopathological only significantly related to (all p 0.002; 102, 0.007; log-rank test). Multivariate analysis revealed ypN (p C second 3R allele has been demonstrated alter tran
