Many studies have examined the association between the CYP 2E1 Rsa Ι /Pst Ι (rs3813867) polymorphism gene polymorphisms and lung cancer risk in various populations, but their results have been inconsistent. The PubMed and CNKI database was searched for case–control studies published up to October 2013. Data were extracted and pooled odds ratios ( OR ) with 95% confidence intervals ( CI ) were calculated. In this meta‐analysis, we assessed 23 published studies involving comprising 4727 lung cancer cases and 6220 controls of the association between CYP 2E1 Rsa Ι /Pst Ι polymorphism and lung cancer risk. For the homozygote c2/c2 and c2 allele carriers (c1/c2 + c2/c2), the pooled OR s for all studies were 0.73(95% CI  = 0.62–0.84; P  = 0.005 for heterogeneity) and 0.84 (95% CI  = 0.77–0.92; P  = 0.001 for heterogeneity) when compared with the homozygous wild‐type genotype (c1/c1). In the stratified analysis by ethnicity, the same significantly risks were found among Asians and mixed population for both the c2 allele carriers and homozygote c2/c2. However, no significant associations were found in Caucasian population all genetic models. This updated meta‐analysis suggests that CYP 2E1 Rsa Ι /Pst Ι c2 allele is a decreased risk factor for the developing lung cancer among Asians and mixed population.
