The incidence of esophageal adenocarcinoma in the western world has been linked to chronic heartburn, regurgitation, and the development of the premalignant epithelium of Barrett's esophagus (BE). However, up to 40% of esophageal adenocarcinomas occur in patients without prior reflux symptoms. We prospectively screened for the presence of BE in asymptomatic subjects older than 50 years of age undergoing screening sigmoidoscopy for colorectal cancer.
