We report a case of early duodenal cancer (2.5 cm in diameter, located in the proximal part) in a 65-year-old female whom segmental resection was performed and a 7- year disease-free survival was achieved. The surgical specimen, showed and a 2.5 × 1.5 × 1.0cm exophytic lesion histopathological examination revealed highly differentiated intramucosal adenocarcinoma. We also report or our review of 122 cases of early duodenal cancer reported in Japan. Intramucosal carcinoma was found in 66%, and submucosal carcinoma in 34% of the patients. The location of the lesion was bulbar in 73 patients (60%), supraampullary in 33 (27%), periamupllary in 5 (4%), and infraampullary in 11 (9%). Distal gastrectomy, including the bulb, was performed in 46 patients, pancreatoduodenectomy in 23, partial resection in 24, endoscopic polypectomy in 25, and segmental resection in 4, including our patient. The frequency of lymph node metastasis is low in early duodenal cancer, so that segmental resection appears to be a reasonable treatment method. |
