Association of GSTP1 and XRCC1 gene polymorphisms with clinical outcomes of patients with advanced non-small cell lung cancer.
We investigated the association between the polymorphisms GSTP1 rs1695 and XRCC1 rs1799782 and rs25487 and the clinical outcome of patients with non-small cell lung cancer (NSCLC) receiving cisplatin-based chemotherapy. Genotyping of GSTP1 rs1695 and XRCC1 rs1799782, and rs25487 was conducted by polymerase chain reaction-restriction fragment length polymorphism analysis. By conditional logistic regression analysis, patients carrying the GG genotype of GSTP1 rs1695 and the AA genotype of XRCC1 rs25487 were found to be more highly associated with response to chemotherapy than were those carrying the AA genotype; the ORs (95%CIs) were 0.13 (0.04-0.37) and 3.37 (1.44-8.53), respectively. Presence of the GG genotype of GSTP1 rs1695 and the GA and AA genotypes of XRCC1 rs25487 was associated with overall survival of NSCLC, and the hazards ratios (95%CI) were 4.35 (1.40-17.92), 0.53 (0.31-0.91), and 0.39 (0.18-0.83), respectively. The results of our study suggest that the GSTP1 rs1695 and XRCC1 rs25487 polymorphisms might affect the clinical outcome of patients with advanced NSCLC receiving cisplatin-based chemotherapy.
