#2299 Expanding the WHO 2017 Classification to Gastrointestinal Tumors: Real-World Data from the R-GETNE Registry
Introduction: The update of the WHO 2017 classification of pancreatic neuroendocrine tumors (NETs) introduces the distinction between NET & NEC G3, based on histological differentiation. However, little is known about the possibility of extending this concept to non-pancreatic NETs.

#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.

#2831 Immunohistochemical Profile of Digestive Neuroendocrine Neoplasms: A Retrospective Analysis in a Single Algerian Institution
Introduction: Neuroendocrine Noplasms (NEN) are rare tumours, but their incidence is clearly increasing in our country due to the improvement of diagnostic means, in particular the generalization of immunohistochemical techniques. The digestive location represents more than 70% of the cases. The anatomopathological study enables to classify the NEN in different prognostic grades according to the degree of differentiation, mitotic index and Ki67.

#2951 Analysis of Discordance between Biopsy Grade and Surgical Pathology Grade in Resected PanNEN Patients
Introduction: In PanNEN cases, treatment strategies are decided by tumor localization, volume and grade. In unresectable or metastatic cases, tumor grade is determined by biopsy specimen obtained from EUS-FNA and diagnostic accuracy of biopsy according to WHO classification 2017 is important for decision making of treatment.

#2279 Expression of FOXM1 in G3 Neuroendocrine Tumors (NET G3) and G3 Neuroendocrine Carcinomas (NEC G3) of the Pancreas and the Intestine
Introduction: G3 gastroenteropancreatic neuroendocrine tumors (G3 NET) and carcinomas (G3 NEC) differ considerably concerning their biological behavior and patients outcome. Whereas the WHO2017 classification for pancreatic NETs proposes a distinction of both groups using the Ki-67 proliferation marker (Klöppel et al. Reviews and Reports 2017), a useful marker for the subclassification of G3 intestinal NETs have not been recommended until now.

#2111 Biliary Neuroendocrine Tumors: A Retrospective Analysis of 28 Patients Since 1991
Introduction: Biliary neuroendocrine tumors represent less than 1% of all neuroendocrine tumors (NETs), and the related clinical study is limited.

#1133 Prognosis of Stage IV Gastroenteropancreatic Neuroendocrine Tumors (GEP-NET) According to the WHO Classification and the Primary Tumor Location
Introduction: WHO classification of GEP-NET is used to predict prognosis, yet survival within each grade shows wide variation. We hypothesized that primary tumor location may be partially responsible of this variability.

#2250 Treatment Outcomes of Patients with Mixed Neuroendocrine Non-Neuroendocrine Neoplasms (MiNEN)
Introduction: Mixed neuroendocrine non-neuroendocrine neoplasms (MiNEN) have been newly defined in the WHO 2017 classification. They are rare tumors, commonly treated in analogy to their non-neuroendocrine (nNE) or neuroendocrine (NE) component without systematic data regarding the optimal therapeutic strategy.

#2267 Large Cell Neuroendocrine Carcinoma of the Lung: Single-Centre Retrospective Cohort Study
Introduction: Large Cell Neuroendocrine Carcinoma (LCNEC) is a rare lung tumour, diagnosed based on high-grade features, presence of neuroendocrine morphology and immunohistochemical evidence of neuroendocrine markers. LCNEC was grouped with the pulmonary neuroendocrine carcinomas in 2015 WHO classification.

#2726 Clinicopathological Characterization of Gastroenteropancreatic Neuroendocrine Tumors in a Single Institute of North Africa: A Retrospective Study of 80 Cases
Introduction: The management of gastroenteropancreatic neuroendocrine tumors (GEP-NETs) is based on a variety of factors including stage, anatomic location, and the presence and type of symptoms.
