#3016 DLL3 Is Expressed in GEP-Neuroendocrine Neoplasms with Loss of RB1 and Has Prognostic Significance
Introduction: The negative notch regulator DLL3 has gained increasing attention in tumors with neuroendocrine features, in particular SCLC, LCNEC and neuroendocrine prostate cancer, both as prognostic marker and candidate therapeutic target. No data are available on the expression of DLL3 in gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs).

#2984 AGTR1 Is Overexpressed in Neuroendocrine Neoplasms, Regulates Secretion and May Serve as a Target for Molecular Imaging and Therapy
Introduction: Peptide receptor targeting has proven to be a pivotal tool for diagnostic imaging and radioligand therapy of neuroendocrine neoplasms (NENs), which frequently express somatostatin receptors (SSTRs) on their cell surface. However, up to 30 % of NEN patients do not benefit from SSTR-based approaches, others develop a resistance.

#2821 Nucleophosmin Expression and Relocation in Pancreatic Neuroendocrine Tumors: Preliminary Data
Introduction: Pancreatic neuroendocrine tumors (PanNETs) are a heterogeneous group of neoplasms with unpredictable clinical course and biological behavior. Nucleophosmin (NPM) is an important multifunctional protein mainly located in the nucleolus. NPM has been reported to be overexpressed in many types of human cancer, activating tumor development and progression. However, the role of NPM in PanNETs is unknown.

#2983 Differential TGF-β Signalling in Typical and Atypical Bronchial Carcinoids
Introduction: Typical and atypical bronchial carcinoids (TBC and ABC) are well-differentiated neuroendocrine neoplasms (NEN). Metastatic BC having low to moderate mitotic count may still be treated with somatostatin analogues and mTOR inhibitors; however, TBC and ABC have been reported to respond very differently to therapy and an effective treatment algorithm is still lacking. TGF-β is known for its ability to activate mTOR pathway and induce epithelial mesenchymal transition, affecting cell pathophysiological capabilities such as proliferation, migration and tissue invasiveness.

#2870 When It Comes to the Diagnostic of Neuroendocrine Neoplasms (NEN), Not All Markers and Clones Were Made Equal. Assessment of 5 Makers in 466 NEN from 10 Anatomical Sites
Introduction: Histological diagnostic of neuroendocrine neoplasms (NEN) relies on morphological criteria and expression of several neuroendocrine marker assessed by immunohistochemistry. Systematic large evaluation of classical (chromogranin A (chrA), synaptophysin (Syn), CD56) and emerging (chromogranin B (chrB), INSM1) markers are lacking.

#3026 IMP3 and Ki-67-Factors of Poor Clinical Outcome in Neuroendocrine Tumors of the Lung
Introduction: Insulin- like growth factor-II messenger RNA- binding protein- 3 (IMP3) is often detected in malignant neoplasm of different sites. Ki-67 proliferative index, although helpful in diagnosing neuroendocrine tumours of lung, has not been recognised as prognostic factor.

#3035 Large-Cell Neuroendocrine Carcinoma of the Lung in Elderly Patient: Case Report and Review of Literature
Introduction: Lung neuroendocrine tumors account for less than 25% of lung cancers.Which is a rare malignant tumor with an aggressive profile has often already affected lymph nodes at presentation and it is de novo metastatic in nearly 40% of cases.

#2682 PAK4-NAMPT Dual Inhibition as a Novel Strategy for Therapy Resistant Pancreatic Neuroendocrine Tumors
Introduction: Pancreatic neuroendocrine tumors (PNET) remain an unmet clinical need. In this study, we show that targeting both nicotinamide phosphoribosyltransferase (NAMPT) and p21-activated kinase 4 (PAK4) could become a synthetic lethal strategy for PNET.

#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.

#2746 Immunohistochemical Biomarker Expression in Gastro-Entero-Pancreatic Neuroendocrine Tumors at ENETS Centre of Excellence, University Hospital Zurich, Switzerland
Introduction: Gastro-entero-pancreatic neuroendocrine tumors (GEP-NET) are a heterogeneous tumor entity with respect to biological behaviour and prognosis. This makes diagnosis and treatment a major challenge.
