title: Epidemiology of columnar-lined esophagus and adenocarcinoma.
abstract: Barrett's esophagus is found in about 1% of the older population and in 3% to 5% of persons with gastroesophageal reflux. It is acquired more commonly by men and the prevalence increases with age. Most cases in the population remain undiagnosed. The incidence of adenocarcinoma of the esophagus and esophagogastric junction is increasing, both being related to Barrett's esophagus. Small areas of intestinal metaplasia are common but of uncertain significance.
