N2 - Aim: Hypoxia-inducible factor (HIF) contributes to the adaptation of tumor cells to hypoxic conditions, so genetic polymorphisms involved in this pathway may affect cellular response to hypoxia and be associated with cancer risk. Thus, we examined the association between the lung cancer risk and genetic polymorphisms involved in the HIF pathway. Methods: This case–control study consists of 462 lung cancer cases and 379 controls from Japan. We examined the effect of HIF1A rs11549467, HIF1A rs11549465, HIF1A rs2057482, HIF2A rs13419896 and vascular endothelial growth factor A (VEGFA) rs833061 on the risk of lung cancer using TaqMan real-time PCR assay. Logistic regression was used to estimate the odds ratio (OR) and its 95% confidence interval (CI) of lung cancer risk. The multiplicative and additive interactions with cigarette smoking were also examined. Results: The AA genotype of HIF2A rs13419896 (OR = 0.54, 95% CI = 0.30–0.99) and the CC genotype of VEGFA rs833061 (OR = 0.42, 95% CI = 0.24–0.75) were significantly associated with a decreased risk of lung cancer after adjustment of potential covariates. Additive interactions between these two polymorphisms and cigarette smoking were also significant. Conclusion: HIF2A rs13419896 and VEGFA rs833061 were significantly related to lung cancer risk, with possible interaction between polymorphisms and cigarette smoking. Further studies are needed to confirm these results.
