Five cases of primary duodenal tumor diagnosed by endoscopic gastric cancer screening

Abstract

We reported five patients with primary duodenal tumor diagnosed at endoscopic gastric cancer screening. Four patients had the superficial non-ampullary duodenal epithelial tumors (SNADT), and one had duodenal-type follicular lymphoma. All tumors were located at the descending portion of the duodenum. We conducted endoscopic treatment in three SNADT patients, surgical resection in one SNADT patient, and chemotherapy in one lymphoma patient. All patients are alive without recurrence after the treatment.

It is necessary to observe the descending portion of the duodenum at the time of endoscopic gastric cancer screening.
