BACKGROUND & AIMS: Barrett's esophagus is associated with adenocarcinoma of the esophagus. The aim of this study was to find the prevalence of Barrett's esophagus in patients with adenocarcinoma of the esophagogastric junction. METHODS: Consecutive, freshly resected surgical esophagogastrectomy specimens were examined, and multiple histological sections were made around the tumor periphery. Barrett's esophagus was defined as specialized columnar epithelium above the esophagogastric junction. Tumors centered or = 3 cm. Specialized epithelium was often found below the esophagogastric junction in controls. CONCLUSIONS: Adenocarcinomas of the esophagogastric junction are associated with short and long segments of Barrett's esophagus. Larger cancers probably overgrow and conceal the underlying specialized columnar epithelium from which they arise.
