Abstract

Genetic variations are linked to DNA repair ability and varied drug metabolism that largely affects the prognosis of antineoplastic agents, including platinum. The purpose of the present meta?analysis was to determine the roles of the genetic variants of the nucleotide excision repair genes on the prognosis of platinum?based chemotherapy in patients with non?small cell lung cancer (NSCLC). A meta?analysis was performed, including 44 original studies with a total number of 5,944 patients with NSCLC according to the search strategy. The tumor responses [complete response, partial response, stable disease (SD) and progressive disease (PD)] were estimated and the Stata package was used for the comprehensive quantitative analyses. The results showed that the XPG C46T polymorphism was significantly associated with tumor chemotherapy when SD or PD was considered as a non?response [TT vs. CC: risk ratio (RR), 1.31; 95% con?dence interval (CI), 1.14?1.5; and P=0.00; TT/CT vs. CC: RR, 1.23; 95% CI, 1.11?1.36; and P=0.00; and TT vs. CC/CT: RR, 1.22; 95% CI, 1.11?1.36; and P=0.00]. No significant association between the ERCC1 C118T/C8092A XPDLys751Gln and XPA A23G polymorphisms and tumor response was found. There was also no evidence found to support the use of the ERCC1 C118T/C8092A XPDLys751Gln and XPA A23G polymorphisms as prognostic predictors of platinum?based chemotherapies in NSCLC in the meta?analysis. For the XPG C46T polymorphisms, a signi?cant association with an objective response was detected. Multiple and large?scale studies are required to further investigate the association between biomarkers and tumor prognosis.
