Biochemical prognostic indicators for pancreatic neuroendocrine tumors and small bowel neuroendocrine tumors

Pancreatic neuroendocrine tumors (PNETs) and small bowel neuroendocrine tumors (SBNETs) are rare tumors that are frequently diagnosied late in the course of the disease. Several biomarkers have been proposed in the literature as prognostic factors for patients with these tumors. This article discusses a recent publication in Annals of Surgical Oncology from the University of Iowa analyzing the effect of different biomarkers on survival in patients with PNETs and SBNETs.
