We aimed to investigate the role of five potential SNPs of XPG gene on the responseto platinum-based chemotherapy in advanced Chinese NSCLC patients. A total of 451 patients with newlydiagnosed and histopathologically confirmed primary NSCLC were consecutively collected. XPG rs2296147,rs4150261, rs17655, rs1047768 and rs2094258 were genotyped by the Taqman real-time polymerase chain reaction(PCR). In our study, we found patients carrying rs1057768 TT genotype had a significantly lower treatmentresponse when compared with the CC genotype (OR=0.38, 95% CI=0.18-0.78). Patients carrying rs1047768 TTgenotype showed a significantly short median PFS (11.2 months) and OS (13.6 months) than CC genotype, andthe hazard ratios (HR) for PFS and OS were 2.06 (1.01-4.50) and 2.29 (1.21-2.49), respectively. Moreover, wefound a significant decreased risk of death from NSCLC among patients carrying the rs2296147 TT genotypewhen compared with the CC genotype, the HR (95% CI) for OS being 0.50 (0.27-0.95). In conclusion, our studyfound that polymorphisms in rs1047768 C/T and rs2296147 C/T are associated with response to platinum-basedchemotherapy in advanced NSCLC, and XPG polymorphisms could be predictive of prognosis.
