#4026 Neuroendocrine tumors in the stomach: An epidemiological analysis of Belgian Cancer Registry data

Introduction: GEP-NEN are rare and heterogeneous tumors including NET, NEC and MiNEN. NET are classified based on mitotic activity and Ki-67 index (G1, 2 and 3), NEC are always high grade (G3). Gastric NEN should be clinically subtyped as this has therapeutic implications (type 1, 2 and 3).

#3135 Endoscopic resection of type I gastric neuroendocrine neoplasia (NEN): A systematic review

Introduction: Although relatively uncommon, the incidence of type I gastric NEN has been rising over time. Since they are considered indolent neoplasms, with a low metastatic potential, endoscopic resection is the treatment of choice. However, correct endoscopic management is not well established.

#2256 Assessment of the Serum Levels of the Soluble Vascular Cellular Adhesion Molecule-1 (sVCAM-1) in Patients with Neuroendocrine Neoplasms

Introduction: Tumor growth and the ability to metastasize is a multistage process involving interactions between cancer cells and the vascular endothelium. These interactions have been reported to be mediated by various molecules including sVCAM-1. We have previously shown elevated serum concentration of sVCAM-1 in 82 neuroendocrine neoplasms (NEN) compared to controls. Here, we present results of the extension of the previous study.

#2125 Subtype Classification and Clinicopathological Features of Gastric Neuroendocrine Neoplasms: 400 Cases of Multicenter Retrospective Analysis

Introduction: Definitions of Type 3 gastric NEN (g-NEN) in ENETS Guidelines 2012 and 2016 are ambiguous and controversial, so Four-type classification has been proposed in China.
