PY - 2018 T2 - Textbook of Complex General Surgical Oncology AB - Pancreatic neuroendocrine tumors (PNETs) account for <3% of all pancreatic tumors and occur with an incidence of 1 to 2 per 100,000 people.1-3 Most are sporadic; however, they may also be associated with multiple endocrine neoplasia 1 (MEN1—parathyroid, pituitary, and PNETs), Von-Hippel-Lindau syndrome (eye, CNS, renal cell carcinoma, pheochromocytoma, and PNETs), or tuberous sclerosis. PNETs are often metastatic at diagnosis, most frequently to the liver. Regional node metastases are particularly common and a regional lymph node dissection is an important part of most surgical procedures. PNETs have a wide spectrum of biologic behavior which is reflected in patients’ 5-year survival rates (97% for insulinomas, 30% for nonfunctional PNETs with metastases). Lesions with higher mitotic rates and Ki-67 index demonstrate a more aggressive biologic behavior.
