ABSTRACT
BACKGROUND: The results of associations between single nucleotide polymorphisms (SNPs) of genes in DNA repairing pathway and lung cancer (LC) risk are inconsistent.
METHODS: We applied allele, dominant and recessive models to explore the risk of researched variants to LC in total LC and subgroups by ethnicity or LC subtypes with a cutoff point of p <0.05.
RESULTS: 76935 cases and 88649 controls from 192 articles were included. Among the analyzed 40 variants from 20 genes, we found 9 statistically significant variants in overall populations by allele model, including five SNPs (rs1760944, rs9344, rs13181, rs1001581 and rs915927) increasing LC risk (odd ratios [ORs]=1.10-1.71) and four SNPs (rs1042522, rs3213245, rs11615 and rs238406) decreasing the risk (ORs=0.75-0.94). We identified rs1042522 and rs13181 as significant variants for LC in three models. Additionally, we identified differential significant SNPs in ethnic and subtype’s analysis with comparison to total population.
CONCLUSIONS: There are five SNPs in DNA repairing pathway associated with increased LC risk and four others decreased LC risk. Besides, the risky SNPs in different ethnicities and various LC subtypes were partly different, and the contribution of different genotypes to risk alleles were various as well.
