We genotyped 1022 surgically resected gastric cancer patients to investigate the prognostic effect of XRCC1 Arg194Trp polymorphism (rs1799782) on gastric cancer in the Chinese population.We found that individuals carrying at least one Trp allele had an increased risk of death compared with those with Arg/Arg homozygote (adjusted hazard ratio =1.34, 95%CI =1.05-1.71) in diffuse-type gastric cancer.Furthermore, this association was more pronounced in patients with T3 or T4 category, positive lymph node metastasis, negative distant metastasis, and stage Ⅲ or V.In conclusion, our results suggest that XRCC1 Arg194Trp could be an independent predictive marker of survival estimation and individualized medicine for gastric cancer.
