#4354 Analysis of gastric NENS in the Czech neuroendocrine tumour registry (2009-2024)

Introduction: Czech Neuroendocrine Tumour Registry is collecting data of NEN patients and their treatment since 2009. We have already analysed SI NENs, pancreatic and thymic NENs. Now we focused on analysis of gastric NENs.

#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.

#2284 The Association between Gastrin and Glucose Serum Concentration in Hypergastrinemic Patients with Gastric Neuroendocrine Tumors Type 1 and ECL-Cells Hyperplasia

Introduction: There is previous data demonstrating that elevated gastrin levels could exert some effect potentiating the glucose-induced insulin secretion.

#1145 The Association Between Gastrin and Glucose Serum Concentration

Introduction: Gastrin is an early incretin candidate, since it is released by oral glucose and potentiates the glucose- induced insulin secretion. It has been shown that only in hypoglycemic or hyperglycemic conditions gastrin release is influenced by changes in blood glucose and insulin concentrations.
