#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.

#4437 Pancreatic metastases in neuroendocrine neoplasia: A systematic review

Introduction: Neuroendocrine neoplasias (NENs) are a heterogeneous group of neoplasms that often metastasise to distant organs, with the liver and bones as common targets. However, metastases to the pancreas are uncommon, accounting for 2–5% of pancreatic malignancies.

#4315 The indolent nature of type 1 gastric neuroendocrine tumours under 1cm: Insights from a dual-centre study

Introduction: Current guidelines primarily recommend endoscopic surveillance for type 1 gastric neuroendocrine tumours (g-NETs) measuring ≤10mm, though these guidelines are largely based on expert consensus rather than strong evidence.

#3441 Management of type-I gastric neuroendocrine neoplasms: A single center’s real world experience

Introduction: Currently, the optimal management of Type-1 gastric neuroendocrine neoplasms (T1gNENs) remains an active issue. The best endoscopic approach still needs to be defined.
