An updated meta-analysis for association of glutathione S-transferase P1 gene polymorphism with the susceptibility of lung cancer.

<bold>Aim Of Study: </bold>The conclusions on the association between glutathione S-transferase P1 (GSTP1) gene polymorphism and lung cancer risk are still debated. This meta-analysis was performed to update the association between GSTP1 and the risk of lung cancer.<bold>Materials and Methods: </bold>The association investigations were identified from PubMed and Cochrane Library, and eligible studies were included and synthesized using meta-analysis method.<bold>Results: </bold>Fifty reports were included into this meta-analysis for the association of GSTP1 A/G gene polymorphism and lung cancer susceptibility. The association between GSTPI G allele/GG genotype and lung cancer risk was found in this meta-analysis (G allele: odds ratio [OR] = 1.08, 95% confidence interval [CI]: 1.02-1.14, P = 0.006; GG genotype: OR = 1.09, 95% CI: 1.00-1.18, P = 0.04). However, the AA genotype was not associated with the susceptibility of lung cancer.<bold>Conclusion: </bold>GSTP1 G allele/GG genotype is associated with the lung cancer susceptibility.
