Pancreatic neuroendocrine tumors are a group of rare, heterogeneous neoplasms that have been increasing in incidence the past few decades largely because of the diagnosis of pancreatic incidentalomas on cross-sectional imaging. Although these tumors are classically associated with clinical syndromes that result from excess secretion of particular hormones, most pancreatic neuroendocrine tumors are nonfunctional tumors presenting with symptoms secondary to mass effect, metastatic disease, or as incidental findings. This article reviews the diagnostic algorithm, surgical management, and available systemic therapies for nonfunctional pancreatic neuroendocrine tumors.
