Esophageal adenocarcinoma most commonly occurs after an insidious progression from IM to LGD to HGD. Therefore, surveillance is increased upon diagnosis of worsening grades of dysplasia. The incidence of esophageal adenocarcinoma is rapidly increasing as middle-aged and elderly demographic sub-groups expand (Peters JH, Hagen JA, DeMeester SR. Barrett's Esophagus. J Gastrointest Surg 2004;8(1):1-17.) In 2004, the American Cancer Society reported that there were 14,250 new cases of esophageal cancer, and 13,300 deaths attributable to esophageal cancer (www.cancer.org). The U.S. National Cancer Institute Surveillance, Epidemiology and End Results Program reported that the increasing incidence of esophageal adenocarcinoma was greater than for any other cancer in the United States (www.cancer.gov).
