Association between ALDH2 Polymorphism and Gastric Cancer Risk in a Korean Population

The association between alcohol and gastric cancer is stronger in East Asians than in other ethnic groups, presumably due to an aldehyde dehydrogenase 2 ( ) polymorphism. Therefore, we investigated the relationship between the rs671 polymorphism and gastric cancer in a Korean population. This case-c...

Abstract The association between alcohol and gastric cancer is stronger in East Asians than in other ethnic groups, presumably due to an aldehyde dehydrogenase 2 ( ) polymorphism. Therefore, we investigated the relationship between the rs671 polymorphism and gastric cancer in a Korean population. This case-control study included 3,245 hospital patients newly diagnosed with gastric cancer and 8,732 population controls. The rs671 genotype was classified as inactive (GG) or active (GA/AA). The risk of gastric cancer was higher in men with the inactive than in those with active (odds ratio [OR], 1.25; 95% confidence interval [CI], 1.09-1.39), whereas no significant association was found between genotype and gastric cancer in women (OR, 1.00; 95% CI, 0.99-1.02). In men, the association between genotype and gastric cancer was stronger in current drinkers. Our findings support the previously reported association between inactive and high risk of gastric cancer.
