#2738 Patient-Derived Organoid Models of Human Neuroendocrine Carcinoma
Introduction: Gastroenteropancreatic neuroendocrine carcinoma (GEP-NEC) is a poorly understood disease with limited treatment options. Due to its low incidence and wide tissue distribution few representative preclinical models are available

#2743 Mimics of Neuroendocrine Neoplasms Identified in a Single Consultation Center between 2009 and 2019
Introduction: Immunohistochemical expression of synaptophysin (SYN), chromogranin (CgA) and cytokeratin are essential for diagnosis of NENs. Non-NENs, however, may occasionally also express NE-markers and cytokeratin and cause diagnostic difficulties.

#2991 Gastroenteropancreatic (GEP) Neuroendocrine Neoplasia G3 (NEN G3) According to 2019 WHO Classification: A Comprehensive Clinicopathological Characterization Including Mismatch Repair (MMR) Proteins, PDL1 Expression and KRAS/BRAF Status
Introduction: In the 2019 WHO FOR NEN’S classification NETG3 have been distinguished from poorly differentiated neuroendocrine carcinoma (NEC). They are heterogeneous group concerning prognosis and treatment benefit.

#74 Non-functioning pancreatic endocrine tumors: diagnostic criteria and surgical treatment
Introduction: Neuroendocrine tumors were considered rare tumors several years ago. Several reports published recently have observed increased incidence of NETs suggesting that NETs are more prevalent than previously reported. Non-functioning pancreatic endocrine tumors (NFPETs), better defined as non-hyperfunctioning, are characterized by the absence of clinical or biochemical evidence of hormone hypersecretion. From the clinical standpoint, NFPETs can be either occasionally encountered or manifest clinically similar pancreatic tumors. Since both NFPET treatment and prognosis significantly differ from that of ductal adenocarcinoma and other pancreatic malignant tumors, an accurate differential diagnosis is needed.

#113 Prolonged cell survival in xenografts from human digestive endocrine tumors
Introduction: Gastroenteropancreatic endocrine tumors have the capacity to achieve very large tumor masses despite usually very low proliferative rates. This suggests that neoplastic endocrine cells may have long life spans, implying the development of specific mechanisms able to promote cell survival.

#536 Orexins Exert a Pro-Apoptotic Effect on Neuroendocrine Tumors (NETs) in an Ex Vivo Culture Model of Tissue Slices
Introduction: Ex vivo culture models of tissue slices are suitable to test the effect of antitumor agents in human tumors. The orexins are neuropeptides binding to G protein-coupled receptors (OX1-R and OX2-R), exerting a pro-apoptotic effect in human colon and pancreatic cancer cell lines.

#920 High Grade (G3) Neuroendocrine Neoplasms Should Be Further Classified According to Morphological Differentiation
Introduction: Neuroendocrine neoplasms (NENs) with a Ki-67 >20% (Grade 3) are classified together as Neuroendocrine Carcinomas (NEC), and are usually considered as poorly differentiated. However Grade (G)3 NENs may be heterogeneous, with some demonstrating a well-differentiated cell morphology.

#1061 Transcatheter Arterial Chemoembolization for Unresectable Metastatic Hepatic Lesions of Pancreatic Neuroendocrine Tumors
Introduction: The blood supply of metastatic hepatic neuroendocrine tumors is mainly supplied by hepatic arteries. For unresectable metastatic NETs, selective embolisation of the hepatic arteries may be therapeutic.
