#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.

#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

#2018 Ex Vivo Activity of Cytotoxic Drugs and Targeted Agents in Small Intestinal Neuroendocrine Tumors
Introduction: Small Intestinal Neuroendocrine Tumours (SI-NETs) are considered to be generally resistant to systemic treatment. To date predictive markers for drug activity are lacking.

#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.

#2280 The BON-SSTR2 Chicken Chorioallantoic Membrane (CAM) Model for the Analysis of Lu-17-DOTATOC Sensitizing Agents
Introduction: Peptide radioreceptor therapy (PRRT) is a promising therapy option for SSTR2-positive pancreatic neuroendocrine neoplasms (NEN). However, therapeutic effects are often not satisfying concerning sensitivity to PRRT. We hypothesize that the slow proliferation of NENs provides sufficient time for the repair of beta-particle induced-DNA damage. The ubiquitin-proteasome-system is involved in DNA damage repair and affected by the proteasome inhibitor bortezomib (Velcade®). The inhibition of DNA damage repair during PRRT may be an option to improve therapy response in NEN. We have recently demonstrated the damage repair inhibitory and pro-apoptotic effect of bortezomib in NEN in vitro (Briest et al., in revision).

#1637 The Effect of the Autophagy Inhibitor Chloroquine (CQ), Alone or in Combination with mTOR Inhibitors, on Neuroendocrine Tumor (NET) Growth and Metastatic Spread in Mouse Models
Introduction: mTOR inhibitors (mTORi) such as RAD001 demonstrated promising anti-cancer effect in NETs. Autophagy, a cell survival mechanism, is activated by mTORi. We have recently shown in the human NET cell line BON1 that autophagy is essential for cell survival. Treatment with CQ alone or together with mTORi robustly inhibited cell proliferation and survival, suggesting that treatment with CQ may potentiate the anti-tumorigenic effects of mTORi.

#2686 Survivorship Care Model for Patients with Metastatic Neuroendocrine Tumors
Introduction: Neuroendocrine tumors(NET)are rare often indolent tumors. Approximately 22% of patients (pt's) present with metastatic disease at diagnosis and can live with metastatic disease for years. These pt's often don't identify as cancer survivors and don't meet the criteria for care in traditional survivorship clinics

#613 Preclinical Evaluation of Novel Combinations of 177-Lutetium Octreotate with Molecular Targeted Agents in Neuroendocrine Tumor Models
Introduction: Peptide receptor radionuclide therapy (PRRT) has been valuable in the treatment of somatostatin receptor-2 (SSTR2) expressing neuroendocrine tumors (NET) but more effective clinical regimens are needed.

#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.
