[A Case of Long-Term Survival after Total Pancreatectomy for Recurrent Pancreatic Cancer in the Remnant Pancreas after Pancreatoduodenectomy].

: We report a case of recurrent pancreatic cancer in the remnant pancreas after pancreatoduodenectomy(PD)that was successfully treated by surgical resection. A woman in her 70s who was treated for multiple lung metastases of breast cancer was referred to our hospital because of obstructive jaundice. A low-density area in the pancreas head(19mm in diameter) and dilatation of the main pancreatic duct were observed on abdominal CT. She was diagnosed with pancreatic head cancer and underwent PD. Twenty months after PD, abdominal CT revealed a tumor in the pancreas tail, and she started receiving chemotherapy containing gemcitabine(GEM)for the diagnosis of recurrent pancreatic cancer in the remnant pancreas. Twelve months after the induction of chemotherapy, we performed surgical resection of the tumor(total pancreatectomy). The pathological diagnosis was moderately differentiated adenocarcinoma, which was similar to the primary lesion, and the tumor was confirmed as recurrence of pancreatic cancer. Although she died of multiple lung metastases of breast cancer 62 months after the total pancreatectomy, the recurrence of pancreatic cancer was not observed without adjuvant therapy during that time.
