#4611 Management strategies and outcomes for type 1 gastric neuroendocrine tumours measuring > 1cm in diameter

Introduction: Although type 1 gastric neuroendocrine tumours (T1-gNETs) are usually considered indolent diseases, the management and the outcome of tumours >1cm remain not well established.

#4234 Association of long-term PPI use with low-risk gastric neuroendocrine tumor

Introduction: Gastric neuroendocrine tumors are rare neoplasms, comprising approximately 2% of all gastric tumors, and develop from enterochromaffin-like (ECL) cells in the gastric mucosa. Type I and II develop due to hypergastrinemia and ECL cell hyperplasia; type III typically occurs sporadically, tend to be more aggressive, present metastatically in > 50% of cases, have normal fasting gastrin levels, and vary histopathologically from well- to poorly differentiated.

#3751 Grade 2 gastric carcinoids type 1 – Not always an indolent disease

Introduction: Gastric carcinoids type 1 (GC1) are increasingly recognized and are usually well-differentiated grade 1 neoplasms. However, rare cases of metastatic spread and adverse prognosis have been described in the literature.

#3549 Patient characteristics in metastatic neuroendocrine tumors of gastric origin

Introduction: Gastric neuroendocrine tumors are also termed gastric carcinoids (GC) and are generally divided in to 3 types. Type 1 are associated with atrophic gastritis and pernicious anaemia, they tend to be multifocal and said not to metastasise. Type 2 GCs are driven by a gastrinomas and tend to be multifocal also. Type 3 are said to be random, solitary, and have a high risk of metastasising.
