p53 protein accumulation, iodine-unstained lesions, and alcohol dehydrogenase-1B and aldehyde dehydrogenase-2 genotypes in Japanese alcoholic men with esophageal dysplasia.

Abstract excerpt

Inactive heterozygous aldehyde dehydrogenase-2 (ALDH2(*)1/(*)2) and less-active alcohol dehydrogenase-1B (ADH1B(*)1/(*)1) increase the risk of esophageal cancer in East Asian drinkers, and esophageal cancer multiplicity is strongly associated with ALDH2(*)1/(*)2. p53 alterations are key molecular events in multifocal carcinogenesis in the esophagus. We studied 260 esophageal-cancer free Japanese alcoholics with...
