Résumé
OBJECTIVE@#To assess the relation between XRCC3 Thr241Met polymorphism and lung cancer susceptibility of populations in East Asia.@*METHODS@#Related studies of XRCC3 Thr241Met polymorphism and lung cancer susceptibility of populations in East Asia were collected through searching the Pubmed, Embase Library, SPRINGER, CNKI and CSSCI.@*RESULTS@#According to the entry criteria, there were 8 case-control studies in the assessing system and there were 6 321 study cases, including 3 215 patients with lung cancer and 3 106 cases without cancers. Meta analysis results showed the combined OR value of the ratio of genotype Thr/Met+Met/Met and Thr/Thr was 1.03 (95%CI: 0.89-1.20) (P>0.05).@*CONCLUSIONS@#XRCC3 Thr241Met polymorphism may not related to lung cancer susceptibility of populations in East Asia. Allele 241Met did not increase the risk of lung cancer.
