Management of small asymptomatic nonfunctioning pancreatic neuroendocrine tumors: Limitations to apply guidelines into real life.
International guidelines suggest a watchful strategy for small nonfunctioning pancreatic neuroendocrine tumors. The aim of this study was to evaluate the management and indications for surgery in patients with asymptomatic nonfunctioning pancreatic neuroendocrine tumors ≤2 cm. ⋯ One-third of patients with asymptomatic small nonfunctioning pancreatic neuroendocrine tumors ≤2 cm underwent surgery. Patient's preference, initial tumor size, and young age were the main determinants of surgical indication. Preoperative diagnostic workup, including 18F-fluorodeoxyglucose positron emission tomography and cytologic grading, seems to be poorly accurate in determining malignant features in these small lesions.
