title: Pancreatoduodenectomy for locally advanced or recurrent colon cancer: report of two cases.
abstract: A 66-year-old man, who had ascending colon cancer which invaded the duodenum, pancreas, and superior mesenteric vein, underwent a curative resection including an extended right hemicolectomy, pylorus-preserving pancreatoduodenectomy, and a partial resection of the superior mesenteric vein. The pathological examination revealed adenocarcinoma of the colon, which directly invaded the duodenum and pancreas, thus causing duodenocolic fistula. Tumor infiltration to the superior mesenteric vein was not histologically proven. Two out of 40 lymph nodes were also involved. The patient is still alive and disease-free 37 months after the operation. A 72-year-old man, with a history of surgery two previous times for ascending colon cancer and its recurrence, underwent a third operation including a resection of the former ileocolic anastomosis en bloc by means of a pylorus-preserving pancreatoduodenectomy with a curative intent. The pathological examination revealed adenocarcinoma of the colon, which directly invaded the duodenum and pancreas. Seven out of 31 lymph nodes were also involved. The patient died of recurrence 24 months after the third operation. These two cases demonstrated the usefulness of a resection of the colon en bloc by means of a pancreatoduodenectomy in patients with either locally advanced colon cancer or locally advanced recurrent colon cancer.
