Adenocarcinoma arising in Barrett's esophagus

A review of nine adenocarcinomas of the esophagus arising in Barrett's epithelium was undertaken. We found the disease among white males disproportionately. Risk factors and incidence rate remain to be clarified. Only one patient was in a surveillance program and only he had carcinoma discovered “early.” He still survives while only one of the eight whose diagnosis followed investigation of symptoms remains alive.
