Pancreatic Surgery with Vascular Reconstruction in Patients with Locally Advanced Pancreatic Neuroendocrine Tumors

Pancreatic neuroendocrine tumors (PNET) are rare neoplasms with better prognosis than most pancreatic malignancies. Surgery of locally advanced PNET remains controversial, and the role of vascular reconstruction in this patient group has yet to be defined. The aim of this study was to evaluate the feasibility and outcome of pancreatic resections with vascular reconstruction in patients with locally advanced PNET. Retrospective analysis of patients who underwent pancreatic surgery with vascular reconstruction for locally advanced PNET at a single institution. Furthermore, a review of the relevant literature on the topic was performed. Seven patients who had undergone vascular reconstruction for locally advanced PNET were identified. Four patients had liver metastases at time of surgery. Postoperative complications developed in four patients with no mortality. Median follow-up time of all patients was 21 (range, 3-58) months. Three patients had disease in remission after 58, 42 and 3 months, respectively. One patient died 35 months postoperatively due to progressive disease, whereas three patients had progression of disease after 21, 9, and 4 months postoperatively. Pancreatic surgery with vascular reconstruction in patients with locally advanced PNET is feasible with acceptable outcome.
