APE1 Asp148Glu gene polymorphism and lung cancer risk: a meta-analysis.
Many studies have examined the association between the APE1 T1349G (Asp148Glu) gene polymorphisms and lung cancer risk in various populations, but their results have been inconsistent. To assess this relationship more precisely, a meta-analysis was performed. The PubMed, Embase, Web of Science, and CNKI database was searched for case-control studies published up to June 2010. Data were extracted and pooled odds ratios (OR) with 95% confidence intervals (CI) were calculated. Ultimately, ten studies, comprising 2,696 lung cancer cases and 3,948 controls were included. Overall, for the G allele carriers (TG + GG) versus homozygote TT, the pooled OR was 1.037 (95% CI = 0.928-1.159 P = 0.001 for heterogeneity), for GG versus TT the pooled OR was 0.997 (95% CI = 0.861-1.154 P = 0.005 for heterogeneity). In the stratified analysis by ethnicity, significantly risks were not found among Asians or Caucasians. However, in the subgroup analyses by smoking status, significantly risks were found among smokers not in non-smokers. This meta-analysis suggested that the APE1 T1349G (Asp148Glu) polymorphism was not associated with lung cancer risk among Asians or Caucasians. But, the APE1 G allele was an increased risk factor for developing lung cancer among smokers.
