Pancreatic neuroendocrine tumors

Current Opinion in Gastroenterology, 2019
Pancreatic 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 ...

Gastric neuroendocrine tumors

Khirurgiya. Zhurnal im. N.I. Pirogova, 2019
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, 2021
The 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.

Pancreatic neuroendocrine tumors

Indian Journal of Gastroenterology, 2012
Pancreatic neuroendocrine tumors (pancreatic NETs) are rare, low- to intermediate-grade neoplasms thought to arise from the pancreatic islets. Recent advances in pathology and our understanding of the biological behavior of this group of tumors has resulted in changes in their nomenclature and how we treat them.

Pulmonary Neuroendocrine Tumors

Surgical Pathology Clinics, 2020
Pulmonary neuroendocrine tumors represent a morphologic spectrum of tumors from the well-differentiated typical carcinoid tumor, to the intermediate-grade atypical carcinoid tumor, to the high-grade neuroendocrine carcinomas composed of small-cell carcinoma and large-cell neuroendocrine carcinoma.

Duodenal neuroendocrine tumors

Khirurgiya. Zhurnal im. N.I. Pirogova, 2019
Significant augmentation of the incidence of duodenal neuroendocrine tumors duodenum has been observed in recent decades. There are 5 histological types of these tumors: gastrinoma (50-60%), somatostatin-producing tumor (15%), inactive serotonin-containing tumors (20%), poorly differentiated neuroendocrine carcinoma (

Gastric Neuroendocrine Tumors

Neuroendocrinology, 2004
Gastric carcinoids are rare neuroendocrine tumors, usually classified as type I, if associated with atrophic body gastritis; type II, if associated with Zollinger-Ellison syndrome and multiple endocrine neoplasia type I, and type III, in the absence of any gastric pathology (sporadic tumors).

Thymic Neuroendocrine Tumors

Thoracic Surgery Clinics, 2014
Thymic neuroendocrine tumors are rare and account for approximately 2% to 5% of all thymic tumors. Despite the suggestion of benign behavior implied by their name, thymic carcinoids have been noted to present a more aggressive biologic behavior than their counterparts in other sites.

Bronchopulmonary neuroendocrine tumors

Cancer, 2008
AbstractBronchopulmonary neuroendocrine tumors (BP‐NETs) comprise ≈20% of all lung cancers and represent a spectrum of tumors arising from neuroendocrine cells of the BP‐epithelium. Although they share structural, morphological, immunohistochemical, and ultrastructural features, they are separated into 4 subgroups: typical carcinoid tumor (TC ...
