Endoscopic mucosal resection (EMR) for the management of poorly differentiated adenocarcinoma of the stomach: a patient who had recurrence and died 4 years after EMR.

Recent studies have explored the possibility of using endoscopic mucosal resection (EMR) to treat lesions with a relative indication for endoscopic therapy. We used EMR to manage poorly differentiated adenocarcinoma, a relative indication for endoscopic treatment, in a patient who requested such treatment and refused surgical intervention. We describe our experience with this patient, who died of tumor recurrence 4 years after the EMR. This case describes the problems of using EMR for the treatment of poorly differentiated adenocarcinoma.
