Gastrointestinal Neuroendocrine Tumors
Neuroendocrine tumors of the gastrointestinal tract are relatively rare neoplasms derived from the diffuse endocrine system (DES), and classified as APUDomas. These neoplasms include mainly pancreatic endocrine tumors (islet cells) and carcinoids. Although malignant, these tumors are often slow-growing. Frequently, these neoplasms secrete hormonal peptides and vasoactive amines that can produce...
متن کاملGastrointestinal Neuroendocrine Tumors
Gastrointestinal carcinoid tumors date back to 1888 when Otto Lubarsch found multiple tumors in the distal ileum of two patients at autopsy (Lubarsch, 1888). The German pathologist Siegfried Oberndorfer was the first who used the term “Karzinoide Tumoren”, the English translation of which is “carcinoid tumor”. He coined this term because these tumors behaved less aggressively than true carcinom...
متن کاملGastrointestinal neuroendocrine tumors.
Gastrointestinal neuroendocrine tumors (GI-NETs) are a genetically diverse group of malignancies that sometimes produce peptides causing characteristic hormonal syndromes. NETs can be clinically symptomatic (functioning) or silent (non-functioning); both types frequently synthesize more than one peptide, although often these are not associated with specific syndromes. Based on data from various...
متن کاملPancreatic Neuroendocrine Tumors
Pancreatic neuroendocrine tumors are usually indolent (slow-growing) by nature and develop over the course of many years. Pancreatic neuroendocrine tumors are usually more indolent, with better prognosis than adenocarcinoma of the pancreas (Carriaga & Henson, 1995). However, aggressive, fast growing pancreatic neuroendocrine tumors exist and different types of pancreatic neuroendocrine tumors e...
متن کاملBiomarkers in pancreatic neuroendocrine tumors.
The aim of biomarkers is to identify patients most likely to benefit from a therapeutic strategy. Pancreatic neuroendocrine tumors are rare neoplasms that arise in the endocrine tissues of the pancreas. Pancreatic neuroendocrine tumors represent 3% of primary pancreatic neoplasms and their incidence has risen. The SMAD4 gene is located on chromosome 18q and someday the SMAD4 gene status may be ...
