#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.

#3364 Sporadic and MEN1-related gastrinoma and Zollinger Ellison syndrome: Differences in clinical manifestation and severity

Introduction: Zollinger-Ellison syndrome (ZES) associated with gastrinoma may be sporadic (Sp), but in 25% of the cases is part of the inherited multiple endocrine neoplasia 1 (MEN1) syndrome. Data comparing Sp and MEN1/ZES forms are scanty.

#2145 Thrombotic Risk in Gastroenteropancreatic Neuroendocrine Tumors: A Single Centre Experience

Introduction: Neuroendocrine neoplasms (NENs) comprise a heterogeneous group of neoplasms associated with paraneoplastic syndromes. Venous thromboembolism (VTE) is a frequent complication in neoplastic patients and it is associated with increased morbidity and mortality. To date, there have been no specific studies in NEN, except for glucagon-secreting tumors

#1823 Effects of Low-Doses Aspirin on Clinical Outcome and Disease Progression in Patients with Gastro-Entero-Pancreatic Neuroendocrine Tumors: Results of a Multicentric Retrospective Study

Introduction: The chemopreventive effect of aspirin (ASA) have been observed in the setting of colorectal cancer. The impact of aspirin use on clinical outcome of patients with gastro-entero-pancreatic neuroendocrine neoplasms (GEP NEN) has not been evaluated yet

#1747 Clinical Characterization of Patients with Neuroendocrine Neoplasm of the Appendix in Ireland and in Italy: A Retrospective Study from Two Tertiary Institutions

Introduction: Appendiceal neuroendocrine neoplasms (aNEN) are rare tumors often diagnosed incidentally at appendectomy. Though most aNEN patients have a positive outcome, distant metastases may rarely occur and the identification of the patients at higher risk is required
