A CASE-REPORT OF RESECTED PRIMARY DUODENAL CARCINOMA ASSOCIATED WITH EARLY GASTRIC-CANCER AND CUMULATIVE RESULTS AT 21 INSTITUTIONS IN JAPAN

A case of primary duodenal carcinoma simultaneously associated with an early gastric cancer is reported. A 72-year-old woman complaining of appetite loss and nausea was admitted in June 1988. Endoscopic examination showed an ulcerative lesion in the angle of the stomach and a Borrmann type 2 tumor in the bulb of the duodenum. Both lesions were revealed to be adenocarcinomas by histological examination of obtained biopsy specimens. Synchronous carcinoma was diagnosed and pancreatoduodenectomy and lymph node dissection were performed. The primary tumor of the duodenum was histologically a moderately differentiated adenocarcinoma, and the gastric cancer was a tumor lmited to the mucosa. Metastasis was recognized in a regional lymph node (No. 14A). There has been no recurrence during the 4-year postoperative follow-up period. This result suggests that pancreatoduodenectomy with systematic regional lymph node dissection can greatly contribute to prolonging the survival of patients with advanced duodenal cancer. This case is very rare, in that curative operation was performed for a primary duodenal carcinoma simultaneously associated with an early gastric cancer.
