#2992 The PanNENomics Project: A Call for an International Collaborative Effort Built on the Success of the LungNENomics Project

Introduction: Neuroendocrine tumors are rare understudied diseases at the molecular level, especially those occurring in sites outside the lung and the gastrointestinal track. This lack of knowledge has strong implications for the clinical management of these diseases (Rindi et al. Mad Pathol 2018).

#2929 Type III Gastric Neuroendocrine Neoplasms: Is Local Excision Sufficient in Selected Cases?

Introduction: As per ENETS Guidelines, patients with type III gastric neuroendocrine neoplasms (t-III g-NEN), need to undergo partial or total gastrectomy. Data for less-extensive resections are limited.

#2861 Targeted Next Generation Sequencing Analysis Reveals the Genetic Characteristics of Gastric Neuroendocrine Neoplasmas

Introduction: there are abundant information about the clinical therapy and pathological features of gastric neuroendocrine neoplasms (gNENs) but little about its genetic characteristics.

#2815 Unexpected High Rate of Metastases in Type 1 Gastric Neuroendocrine Neoplasia

Introduction: Gastric neuroendocrine neoplasms (gNEN) represent about 7.5% of gastroenteropancreatic NEN (gepNEN), classified in: type 1 (70-80%), related to autoimmune gastritis, type 2 (5%), related to Zollinger-Ellison syndrome in multiple endocrine neoplasia 1 and type 3 (15-20%), in absence of hypergastrinemia or mucosal atrophy.

#2790 Trends of Incidence and Prognosis of Gastric Neuroendocrine Neoplasms - A Study Based on SEER and Our Multicenter Research

Introduction: The incidence of gastric neuroendocrine neoplasms (GNENs) is increasing but we still lack effective tools for risk stratification so far.
