In persons with inactive ALDH2, the body fails to metabolize acetaldehyde rapidly, leading to excessive accumulation of acetaldehyde. Inactive heterozygous ALDH2 enhances the risk of esophageal squamous cell carcinoma (SCC) in Japanese male drinkers.<\/jats:p><jats:p><jats:bold>Methods: <\/jats:bold> We studied whether this is the case for women. The risk factors of esophageal SCC were examined in 52 Japanese women with esophageal SCC and 412 cancer\u2010free Japanese women.<\/jats:p><jats:p><jats:bold>Results: <\/jats:bold> The increasing trend in cancer risk according to the quantity of alcohol consumption was significantly steeper in women with inactive heterozygous ALDH2 than in those with active ALDH2 [adjusted odds ratios (ORs) (95% confidence intervals (CIs)) per +7 U\/wk increment of alcohol drinking were 3.91 (2.09\u20137.31) and 1.39 (0.92\u20132.09), respectively; <jats:italic>p<\/jats:italic>=0.006 for difference in OR; 1 Ut=22 g of ethanol]. The results obtained using an alcohol\u2010flushing questionnaire were essentially comparable with those obtained by ALDH2 genotyping [adjusted ORs (95% CIs) per +7 U\/wk increment of alcohol drinking were 3.94 (1.87\u20138.31) and 1.46 (0.96\u20132.23) in those with and without flushing, respectively; <jats:italic>p<\/jats:italic>=0.021 for difference in OR].
