Meta-analysis of ADH1B and ALDH2 polymorphisms and esophageal cancer risk in China

摘要

AIM: To evaluate whether alcohol dehydrogenase-1B (ADH1B) His47Arg and aldehyde dehydrogenase-2 (ALDH2) Glu487Lys polymorphism is involved in the esophageal squamous cell carcinoma (ESCC) risk in Chinese Han population. METHODS: Seven studies of ADH1B and ALDH2 genotypes in Chinese Han population in 1450 cases and 2459 controls were included for meta-analysis. Stratified analyses were carried out to determine the genealcohol and gene-gene interaction with ESCC risk. Potential sources of heterogeneity betwee...
