#4233 Characteristics of gastric neuroendocrine tumors type 1

Introduction: Gastric neuroendocrine tumors type 1 (gNET 1) are the most prevalent among other gNET. These neoplasms demonstrate low growth rate and low malignant potential. Recent publications describe polymorphism of gNET 1, which may indicate a various course of the disease.

#4221 Assessing the frequency of type I gastric neuroendocrine neoplasms in autoimmune atrophic gastritis: A multi-center study in Italy

Introduction: In autoimmune atrophic gastritis (AAG), mucosa morpho-functional changes lead to hypo-achlorhydria, hypergastrinemia, and enterochromaffin-like (ECL) cells proliferation, escalating the risk of type I gastric neuroendocrine neoplasms (gNENs). Longitudinal studies on the AAG-gNENs association are scanty.

#3861 Incidence and prevalence of gastric neuroendocrine tumors in patients with chronic atrophic autoimmune gastritis

Introduction: The incidence of type I gastric neuroendocrine neoplasms (gNEN) has increased substantially over the past 50 years, although studies evaluating the association with chronic autoimmune atrophic gastritis (CAAG) in the long term have been inconsistent.

#830 The Predictive Value of Gastrin Levels for the Diagnosis of Gastric Enterochromaffin-like Cells Hyperplasia, in Patients with Hashimoto’s Thyroiditis

Introduction: Gastrin and chromogranin A (CgA) levels have been tested for the diagnosis of enterochromaffin-like cell hyperplasia (ECLH), in patients with type 1 diabetes and autoimmune atrophic gastritis but there are no data for patients with Hashimoto's thyroiditis (HT).

#621 Occurrence of Type 1 Gastric Carcinoid In Patients with Autoimmune Chronic Atrophic Gastritis

Introduction: The actual incidence of type1 gastric carcinoids (GC1) as a long-term complication of chronic autoimmune atrophic gastritis (CAAG) remains to be clarified as studies are few.
