Also known as Gastrin Secreting tumor, Gastrin cell tumour, malignant gastrinoma, Gastrin-Producing Neuroendocrine Tumor, Gastrin-Producing NET, G-Cell Gastrin Producing Tumor, G-Cell Tumor

Gastrinomas are neuroendocrine tumors (NETs), usually located in the duodenum or pancreas, that secrete gastrin and cause a clinical syndrome known as Zollinger–Ellison syndrome (ZES). A large number of gastrinomas develop in the pancreas or duodenum, with near-equal frequency, and approximately 10% arise as primary neoplasms in lymph nodes of the pancreaticoduodenal region (gastrinoma triangle).

Gastrinomas are neuroendocrine tumors (NETs), usually located in the duodenum or pancreas, that secrete gastrin and cause a clinical syndrome known as Zollinger–Ellison syndrome (ZES). A large number of gastrinomas develop in the pancreas or duodenum, with near-equal frequency, and approximately 10% arise as primary neoplasms in lymph nodes of the pancreaticoduodenal region (gastrinoma triangle).

Most gastrinomas are sporadic (75–80%), whereas approximately 20–25% are associated with multiple endocrine neoplasia type 1 (MEN-1). Over 50% of gastrinomas are malignant and can metastasize to regional lymph nodes and liver. One fourth of gastrinomas are related to multiple endocrine neoplasia type 1, Zollinger–Ellison syndrome, peptic ulcer disease.
