Gastroenterology Clinics of North America, 2016
Neuroendocrine tumors are increasingly diagnosed, either incidentally as part of screening processes, or for symptoms, which have commonly been mistaken for other disorders initially. The diagnostic workup to characterize tumor behaviour and prognosis focuses on histologic, anatomic, and functional imaging assessments. Several therapeutic options exist

Gastroenteropancreatic Neuroendocrine Tumors
Gastroenterology Clinics of North America, 2022Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are the most common type of neuroendocrine tumors and are being increasingly identified in clinical practice. The diagnosis, staging, management, and surveillance of GEP-NETs rely heavily on endoscopy, and consequently, it is important for gastroenterologists to have a solid understanding of these

Pancreatic neuroendocrine tumors
Current Problems in Surgery, 2013Pancreatic neuroendocrine tumors (PNETs) have an incidence of approximately 1 per 100,000 individuals per year, and account for 1–2% of all pancreatic tumors. The annual incidence in the United States is about 3.65 per 100,000 population. Although they may manifest at any age, they most often occur in the fourth to sixth decades of life. Most PNETs are

Pancreatic Neuroendocrine Tumors
Surgical Pathology Clinics, 2016Pancreatic neuroendocrine neoplasms include well-differentiated pancreatic neuroendocrine tumors (PanNETs) and neuroendocrine carcinomas (NECs) with well-differentiated PanNETs accounting for most cases. Other pancreatic primaries and metastatic carcinomas from other sites can mimic pancreatic neuroendocrine neoplasms.

Pancreatic neuroendocrine tumors
Current Opinion in Gastroenterology, 2019Pancreatic neuroendocrine tumors (pNETs) are a rare, heterogeneous group of pancreatic neoplasms with a wide range of malignant potential. They may manifest as noninfiltrative, slow-growing tumors, locally invasive masses, or even swiftly metastasizing cancers.In recent years, because of the increasing amount of scientific literature available for ...

Gastrointestinal neuroendocrine tumors are rare neoplasms. Currently, incidence of gastric neuroendocrine tumors (gNETs) is being significantly increased. There are 3 groups of gNETs: types I, II and III. Each type has important features regarding clinical picture, prognosis and treatment strategy. Type I is the most common (70-80%) and associated with

Pituitary neuroendocrine tumors: a model for neuroendocrine tumor classification
Modern Pathology, 2021The classification of adenohypophysial neoplasms as "pituitary neuroendocrine tumors" (PitNETs) was proposed in 2017 to reflect their characteristics as epithelial neuroendocrine neoplasms with a spectrum of clinical behaviors ranging from small indolent lesions to large, locally invasive, unresectable tumors.
