Barrett's esophagus-is it bad for your health?

Barrett's esophagus is a clearly recognized risk factor for the development of esophageal adenocarcinoma. Despite the rapidly increasing incidence rate of esophageal adenocarcinoma, the vast majority of patients with Barrett's esophagus will never go on to develop this cancer. Furthermore, esophageal adenocarcinoma is a rare cause of death in Barrett's esophagus patients, and most of these patients die from other causes. While some studies demonstrate that the overall survival of patients with Barrett's esophagus is no different than that of the general population, others have suggested that Barrett's esophagus may be associated with increased mortality. Work by Solaymani-Dodran et al., in the current issue of the American Journal of Gastroenterology, found that all cause mortality was increased by 37% and mortality from causes other than esophageal cancer was increased by 23% compared to the general population, differences that were eliminated when adjusted for ischemic heart disease. Findings such as these point out the need for large, well-done epidemiologic studies of Barrett's esophagus cohorts in order to develop a better understanding of the natural history of this disease.
