A Case of Pancreatic Neuroendocrine Neoplasm with Para-aortic Lymph Node Metasatases without Reccurence for 7 Years after Resection

Abstract

The patient was a 49-year-old man. He underwent pancreaticoduodenectomy and para-aortic lymph node dissection for a pancreatic neuroendocrine tumor with para-aortic lymph node metastases. Seven years after the operation, the patient remains alive without recurrence. According to the guideline, resection of primary and metastatic lesions is indicated for pancreatic neuroendocrine tumors with resectable distant metastases, and prolongation of life expectancy can be expected. Multidisciplinary treatment is recommended. However, there are many reports of resection of metastatic lesions in the liver and few reports of resection of pancreatic neuroendocrine tumors with para-aortic lymph node metastasis, and its long-term prognosis is not clear. A case of a pancreatic neuroendocrine tumor with para-aortic lymph node metastases suggesting that prolonged survival may be obtained by curative resection is reported.
