Many epidemiologic studies have investigated the association between myeloperoxidase (MPO) G-463A polymorphism and lung cancer risk, but the results were controversial. We performed a meta-analysis of 25 studies on MPO polymorphism and lung cancer risk published before July 2013. The allele of A was found to be associated with decreased risk of lung cancer compared with G allele (OR, 0.90; 95 % CI, 0.82-0.98) in the general population. The significant association remained in the comparison between AA + AG and GG (OR, 0.92; 95 % CI, 0.87-0.98). When it was stratified according to Asian population, the association between MPO polymorphism and lung cancer risk was further strengthened. However, no associations were found in the Caucasian population. This meta-analysis has demonstrated that MPO polymorphism might contribute to individual's susceptibility to lung cancer in Asian population. Caucasian authors could re-investigate the association between MPO polymorphism and lung cancer risk with more specific participants. Future studies focusing on interactions between combined genes and environmental risk factors are warranted.
