#2692 Development of Ex-Vivo Models of Metastatic Neuroendocrine Neoplasms
Introduction: The lack of relevant in-vivo and in-vitro models has precluded investigations of the pathophysiology of metastatic NENs. Organotypic tumour slices retain the complexity of tumours in-vivo without extensive manipulation of the tissue.

#2810 Development of a Personalized Human Immunocompetent Ex-Vivo Model of Neuroendocrine Liver Metastasis Using Precision Cut Tissue Slice Technology
Introduction: Liver metastasis (LM) are very frequent (65-95%) and represent a crucial prognostic factor in patients with gastroenteropancreatic neuroendocrine neoplasms (GEP NENs). The paucity of relevant experimental models has limited the understanding of the pathophysiology of NENs and the development of efficient therapeutic strategies

#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

#2898 Novel Preclinical Models of Small Bowel Neuroendocrine Tumors for Drug Screening
Introduction: The incidence of neuroendocrine tumors (NETs) from the small bowel (SBNETs) has increased markedly over the past several decades. Many patients with these tumors present with metastatic disease, and research into new treatment options for these tumors have been hindered by the limited number of patient-derived SBNET cell lines and in vivo models available for drug testing.

#2908 Re-Cellularised Human Pancreas 3D Scaffolds as a Novel Model for Biomarker Discovery in Pancreatic Neuroendocrine Tumours (pNETs)
Introduction: The lack of preclinical models of pNETs has challenged identification of tissue specific biomarkers of disease. Culturing cancer cells in their native tissue enables the close study of cell-ECM interaction and tissue remodelling. The biological products of such interactions can form a basis for discovery of novel biomarkers of the disease, and were previously linked with a range of inflammatory and malignant conditions.

#3010 International Validation of a Nomogram to Predict Recurrence after Resection of Grade 1 and 2 Pancreatic Neuroendocrine Tumors
Introduction: A prediction model to predict recurrence within 5 years after surgery for nonfunctional pancreatic neuroendocrine tumors (PanNets) was recently published. This model includes WHO tumor grade, lymph node status and perineural invasion as predictors.

#2980 Metabolic Dysregulation and Circadian Clock in Cellular Models of Neuroendocrine Tumors
Introduction: The circadian clock genes encode transcription factors whose interaction with nuclear receptors allows the regulation of cellular metabolism.The invalidation of the genes of the clock core is associated with the development of many endocrine diseases including neuroendocrine cancer. Recently, the family of transcriptional coactivators PGC-1a has been identified as a key element in the integration of cellular metabolic state with the circadian clock. PRC, as a member of the PGC-1 family, was able to interact with several transcription factors, including the CLOCK factor. The specific induction of this PRC factor by the cell cycle, to modulate the energy function, the MAPkinase pathway and the expression of microRNAs, makes it a key factor in the metabolic adaptation of cancer cells.

#2963 Intrinsic Gene Programs in Metastasis-like Primary Subtype Is Associated with Early Metastatic Evolution in Pancreatic Neuroendocrine Tumours
Introduction: Three molecular subtypes of pancreatic neuroendocrine tumours (PanNETs) have been described: insulinoma-like, intermediate and metastasis-like primary (MLP). The Latter is a non-functional tumours with highly metastatic potential. A mouse model of PanNET showed that MLP subtype has two different pathways of progression including stem/progenitor and epithelial-to-mesenchymal transition. However, the evolution of metastasis in patients requires further studies.

#2742 Anti-Tumor Effects of Semaphorin 4D Blockade Unravel a Novel Pro-Invasive Mechanism of Vascular Targeting Agents
Introduction: One of the main consequences of inhibition of neovessel growth produced by angiogenesis inhibitors is increased intratumor hypoxia. Growing evidence indicates that tumor cells escape from this hypoxic environment to better nourished locations, presenting hypoxia as a positive stimulus for invasion. Particularly, anti-VEGF/R therapies produce hypoxia-induced invasion and metastasis in a spontaneous mouse model of pancreatic neuroendocrine cancer, RIP1-Tag2.

#2974 MEK/RAF and PARP as Novel Targets in Neuroendocrine Neoplasms – First Results from a Molecular in vitro Tumor Board
Introduction: Neuroendocrine neoplasms (NEN) are a heterogeneous group comprising well differentiated neuroendocrine tumors (NET) and poorly differentiated neuroendocrine carcinomas (NEC). Although, major progress has been made in the development of targeted therapies in various cancers, establishment of a promising personalized therapy in NEN is still pending. So far, a lack of suitable preclinical models represent a major challenge concerning the validation of a mutational based targeted therapy (MBTT)
