#4441 Gastric neuroendocrine neoplasms in younger patients: A retrospective single-centre study

Introduction: Gastric neuroendocrine neoplasms (gNENs) are rare neoplasms arising from stomach enterochromaffin-like (ECL) cells. Type I gNENs are the most common type, typically indolent and arising in the context of chronic atrophic gastritis (CAG). While type I gNENs are generally diagnosed in pts over 50, their occurrence in younger pts raises concern about the onset of CAG-related complications at an earlier age, potentially affecting tumour growth and clinical outcomes. Young-oriented studies on type I gNETs are still lacking in literature.

#4400 Analysis of clinicopathologic features and prognosis of 8096 patients with gastric neuroendocrine neoplasms

Introduction: Gastric neuroendocrine neoplasms (G-NENs), as rare tumours, continue to increase in morbidity and mortality. The specificity of the clinical features of G-NENs has led to a lack of awareness of this 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.

#3665 Endoscopic submucosal dissection for gastric neuroendocrine neoplasms – A multicentre retrospective study

Introduction: The optimal endoscopic management for Gastric Neuroendocrine Neoplasms (G-NENs) is yet to be determined, and data are limited in the literature.
