There is a clear association between Barrett's esophagus (BE) and esophageal adenocarcinoma. National guidelines recommend endoscopic surveillance of BE patients to detect and treat early esophageal cancers. To date, however, the association between BE surveillance and survival has not been evaluated in any population-based studies. In this population-based cohort study of 589 patients with esophageal or gastric cardia adenocarcinoma, researchers identified 23 patients in whom BE (18 esophageal, 5 cardia) was diagnosed more than 6 months before cancer.
Among the 23 BE patients, 15 had surveillance-detected cancers, and 8 had not received endoscopic surveillance after the initial BE diagnosis. Five-year survival was 73% for patients with surv…
