摘要
We performed a study to investigate the role of ERCC1 (rs11615, rs2298881, and rs3212986) and ERCC2 (rs13181, rs238406, and rs1799793) polymorphisms in the prognosis of gastric cancer. A total of 346 patients with gastric cancer were recruited between May 2009 and May 2012. Single nucleotide polymorphism genotyping was performed using the Sequenom MassARRAY platform. The GA+AA genotype of ERCC2 rs1799793 showed significant and favorable response to chemotherapy than the wide-type GG genotype in multivariate analysis (OR = 1.78, 95% CI = 1.13-2.81). In a Cox proportional hazard model, carriers of ERCC2 rs1799793 GA+AA genotype exhibited longer duration of survival than did those with the GG genotype (hazards ratio = 0.57, 95% CI = 0.35-0.92). In conclusion, our study suggests that ERCC2 rs1799793 polymorphic variation could be used as a predictor for the prognosis of gastric cancer.
