XPG polymorphisms are associated with prognosis of advanced non-small cell lung cancer treated with platinum-based doublet chemotherapy
We conducted a cohort study to investigate whether 3 potential single nucleotide polymorphisms (SNPs) in the xeroderma pigmentosum complementation group G (XPG) gene could predict the survival of advanced non-small cell lung cancer (NSCLC) patients treated with platinum-based doublet chemotherapy. We enrolled 262 patients with histologically confirmed NSCLC between November 2007 and December 2008 in this study. The 3 SNPs (rs2296147T>C, rs2094258C>T, and rs873601G>A) were genotyped using polymerase chain reaction-restriction fragment length polymorphism analysis.
