Gastric neuroendocrine tumors
Gastric Neuroendocrine Tumors (NET)s are classified on the basis of criteria that are common to all gastrointestinal and pancreatic neuroendocrine neoplasms. Most neuroendocrine neoplasms of the stomach are NETs –well differentiated, nonfunctioning enterochromaffin–like(ECL) cell carcinoids (ECL cell NETs)-arise predominantly in the corpus-fundus region [1]. Three distinct types are recognized :
متن کاملInsights into gastric neuroendocrine tumors burden
Type 1 gastric neuroendocrine tumors (gNETs) are usually small lesions, restricted to mucosal and sub-mucosal layers of corpus and fundus, with low aggressive behavior, for the majority of cases. Nevertheless, some cases present aggressive behavior. The increasing incidence of gNETs brings together a new relevant problem: how to identify potentially aggressive type 1 gNETs. The challenging prob...
متن کاملA Rare Gastric Carcinoma - Neuroendocrine Tumors
Neuroendocrine tumors, or more properly gastro-entero-pancreatic tumors (GEP-NETs), are cancers of the interface between the endocrine (hormonal) system and the nervous system. A neuroendocrine tumor begins in the hormone-producing cells of the body’s neuroendocrine system, which is made up of cells that are a cross between traditional endocrine cells (or hormone-producing cells) and nerve cell...
متن کاملThe biological relevance of gastric neuroendocrine tumors.
Gastric neuroendocrine tumors were originally thought to have a low incidence (three percent). Since endoscopic diagnostic procedures have become clinical routine, they are now found more frequently (relative incidence up to 41 percent). In recent years, classifications have been developed that attempt to consider the biological relevance of these tumors. Four types of gastric neuroendocrine tu...
متن کاملMulticentric Type 3 Gastric Neuroendocrine Tumors
A 50-year-old woman with incidentally detected multiple gastric polyps and biopsy-proven neuroendocrine tumor (NET) was referred to our hospital. More than 10 polypoid lesions (less than 15 mm) with normal gastric mucosa were detected from the gastric body to the fundus. The serum level of gastrin was within the normal limits. There was no evidence of atrophic changes on endoscopy and serologic...
