[A Case with Long Survival after Total Remnant Pancreatectomy for Recurrence of Pancreatic Body Cancer]

A 56-year-old man underwent distal pancreatectomy due to pancreatic body carcinoma in 2009, at the age of 46. There had been no sign of metastasis and recurrence until levels of tumor markers began to increase in January 2014. PET scan, CT scan, and other examinations showed a possible carcinoma in the pancreas head. The patient underwent total remnant pancreatectomy. The tumor was located in the uncinate process of the pancreas with infiltration of the portal vein. The pathological diagnosis of the tumor was moderately differentiated adenocarcinoma. The ductal lumen structure was relatively maintained and the cytoplasm was comparatively clear. Since its pathological findings were similar to those observed in 2009, the tumor appeared to be a recurrence of the tumor resected at that time. The patient had received postoperative chemotherapy and remains alive in 2019 without recurrence. While there is evidence that surgical resection for the recurrence of other cancers such as colon cancer may improve patient survival, it remains unclear if surgical resection of recurrence in the remnant pancreas after pancreatectomy of pancreatic cancer is feasible. We report a case with long survival after surgical resection of a pancreatic carcinoma recurrence in the remnant pancreas.
