Heterogeneity of Type 1 Gastric Neuroendocrine Neoplasms Abstract #1822

Introduction: Type 1 gastric Neuroendocrine Neoplasms (gNENs) are defined when atrophic body gastritis is associated. They are mostly multiple, small, with a low grade histology with low metastatic risk. Data on factors associated with malignant tumor behavior in these patients are scarce.
Aim(s): Identify subgroups of patients with potential risk of malignant behavior among type 1 gNENs.
Materials and methods: Multi-center retrospective study including type 1 gNENs. Tumors were divided according ENETS staging and grading system. Pearson coefficient was used to assess correlation.

#1803 Type 3 Gastric Neuroendocrine Neoplasms: Relationship Between Tumor Size, Ki67 and Clinical Outcome
Introduction: Sporadic type 3 gNENs are usually malignant with high metastatic potential, mostly large, with a high grade histology. However, little is known on the relationship between tumor size, proliferative index Ki67, and clinical outcome

#2683 Clinicopathological Features and Prognostic Analysis of 227 Cases with Well-Differentiated Gastric Neuroendocrine Tumors
Introduction: Gastric neuroendocrine neoplasms (g-NENs) are a group of rare tumors with a strong heterogeneity, subdivided as well-differentiated neuroendocrine tumors (NETs, type 1-3 g-NETs) and poorly-differentiated neuroendocrine carcinoma(NECs). WHO classification(2019) for digestive system tumours has carried out a new classification and grading criteria for NENs of the gastrointestinal tract recently, there is very few relevant clinical data based on this new classification, especially for gastric NETs(g-NETs).

#2845 Primary Tumour Resection and PRRT of NEN Stage IV - Are There Differences in Grading?
Introduction: The resection of primary tumours (PT) in patients with stage IV NEN is still a matter of debate. The resection of tumours with a low proliferation index (G1/G2) is more accepted then the resection of high proliferative tumours (G3-NET / G3-NEC).
