We investigated associations between the risk of lung cancer in residents of the coal-mining region and polymorphisms in the genes APEX1 (rs1130409), hOGG1 (rs1052133), XRCC1 (rs25489, rs25487), XRCC2 (rs3218536), XRCC3 (rs861539), ADPRT/PARP1 (rs1136410), XPD/ERCC2 (rs13181), XPG/ERCC5 (rs17655), XPC (rs2228001), ATM (rs1801516), and NBS1 (rs1805794).
This meta-analysis suggests that XPC Lys939Gln polymorphism may contribute to lung cancer risk, which needs further validation in single larger studies.
This meta-analysis including 13 case-control studies evaluated the associations between three commonly XPC polymorphisms (Lys939Gln, Ala499Val, and PAT(-/+)) and lung cancer susceptibility.
We found that XPA A23G and XPC Lys939Gln polymorphisms may be risk factors for lung cancer and evidence that positive interactions between the polymorphisms in XPA/XPD and XPC/XPD may occur.
To test this hypothesis, we investigated the potential association of 7 XPC polymorphisms (-449G-->C, -371G-->A, -27G-->C, Val499Arg, PAT-/+, IVS11-5C-->A and Lys939Gln) and their haplotypes with lung cancer risk in a Korean population.
