AbstractWe investigated the association between the clinical outcome and GSTP1 and XRCC1 gene polymorphisms in advanced NSCLC patients with cisplatin-based chemotherapy. We prospectively recruited 325 NSCLC patients between January 2010 and January 2014. Genotypes of GSTP1 A313G, XRCC1 Arg194Trp, Arg280His and Arg399Gln were conducted using polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) assay. AG and GG genotypes of GSTP1 A313G were correlated with a higher CR + PR when compared with AA genotype. Furthermore, GA and AA genotypes of XRCC1 Arg399Gln were associated with more CR + PR when compared with GG genotype. In the Cox proportional hazards model, GG genotype of GSTP1 A313G was significantly correlated with a longer median survival time when compared with AA genotype, and it is associated with a heavy decreased risk of death from NSCLC. Moreover, GA and AA genotypes of XRCC1 Arg399Gln had a significantly longer median survival time, and GA and AA genotypes were significantly associated with a moderate reduced risk of death from NSCLC. GSTP1 A313G and XRCC1 Arg399Gln gene polymorphisms might influence the response to cisplatin-based chemotherapy and affect the clinical outcome of advanced NSCLC.
