【 摘 要 】

We conducted a perspective study to assess the association between ERCC1 and XPF polymorphisms and response to chemotherapy and clinical outcome of NSCLC receiving chemotherapy. Between May 2009 and May 2011, a prospective study was conducted on 240 NSCLC cases. Genotypes of ERCC1 (rs11615, rs3212986 and rs2298881) and XPF (rs2276465 and rs6498486) were performed by Polymerase Chain Reaction Restriction Fragment Length Polymorphism (PCR-RFLP) assay. By conditional logistic regression analysis, patients carrying AA genotype of ERCC1 rs11615 showed more CR+PR to chemotherapy when compared with GG genotype, and the adjusted OR (95% CI) was 2.73 (1.21-6.18). By Cox regression analysis, AA genotype of ERCC1 rs11615 was associated with longer overall survival of NSCLC, and the adjusted HR (95% CI) was 0.38 (0.14-0.96). In conclusion, our study found that ERCC1 rs11615 polymorphism can influence the chemotherapy response and overall survival of NSCLC patients receiving cisplatin-based chemotherapy.
