#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.

#108 Everolimus (RAD001) induces tumor response in patients with medullary thyroid cancer: an in vivo and in vitro study
Introduction: Medullary thyroid cancer (MTC) is a neuroendocrine tumor (NET) of the thyroid C cells which is known to express somatostatin receptors. Octreotide, a somatostatin analogue exerting both antisecretory and antitumor activity in different types of NETs, has shown low efficacy in MTC. Everolimus (RAD001), an inhibitor of mTOR, has shown antitumor effects in patients with NETs and synergistic effects when combined with octreotide. Until recently, RAD001 has never been evaluated in MTC.

#741 Lanreotide Activity and Synergy in Combination with Targeted Agents in Gastrointestinal Neuroendocrine Tumors (GI-NET): Ex Vivo Analysis of Programmed Cell Death (EVA/PCD) in GI-NETs Isolated from Patients with Advanced Disease
Introduction: Somatostatin receptor ligation can affect vascular signals, induce apoptosis and provide objective responses in some GI-NET patients.

#1436 Up-Regulation of the Immunoregulatory Enzyme Indoleamine-2,3-Dioxygenase (IDO) with Consecutive Tryptophan Depletion Predicts Death in Patients with Neuroendocrine Neoplasia
Introduction: Data from a considerable number of malignancies demonstrate that depletion of the essential amino acid tryptophan via induction of the immuno-regulatory enzyme Indoleamine-2,3-dioxygenase (IDO) serves as an important tumour escape strategy and is of prognostical importance.

#1545 In Vivo Expression of Survivin and XIAP in Medullary Thyroid Carcimoma
Introduction: Medullary thyroid carcinoma (MTC) accounts for approximately 5 % of all thyroid malignancies. Although surgery remains the first line therapy with curative intention, for advanced MTC current chemotherapeutic regimes do not provide promising results. Consequently, the identification of biologically relevant biomarkers that are associated with MTC progression may provide novel therapeutic targets.

#1107 The Chicken Chorioallantoic Membrane Assay as a Preclinical Model for the Research of Rare Gastrointenstinal Neuroendocrine Tumours
Introduction: Preclinical trials of cancer therapeutics require both in vitro and in vivo evaluations. For neuroendocrine tumours (NET) studies are limited to cell lines, thus xenograft models are needed for screening and evaluation of anti-cancer drugs. The chick chorioallantoic membrane (CAM) assay is a well-established model system to investigate tumour growth, angiogenesis and metastasis.

#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.

#602 Antitumoral Effect of Everolimus in Preclinical Models of Poorly Differentiated Neuroendocrine Carcinomas
Introduction: For the small and large cells poorly differentiated neuroendocrine carcinomas (PDNECs) emergency treatment remains the combination cisplatin/etoposide. However, recent studies suggest that targeted therapies could be a therapeutic option for this group of highly aggressive carcinomas.

#1115 Cancer Stem Cells in Small Intestine Neuroendocrine Cell Line P-STS: Isolation and Molecular Characterisation
Introduction: Cancer stem cells (CSCs) represent a small subpopulation of tumour cells responsible for invasive tumour growth. Even though the presence of CSCs in neuroendocrine tumours is documented, their role in neuroendocrine tumourigenesis and metastasis is not defined as yet.

#1156 Characterisation, Measurement and Biodistribution of an Improved Formulation of [Lu-177]-Octreotate
Introduction: Lu-177 can be made with high specific activity and no other isotopes of lutetium present, referred to as “no carrier added” (nca) Lu-177. We have radiolabelled DOTA-conjugated peptide DOTA‐(Tyr3)‐octreotate (Auspep, Melb., AUS) with nca Lu-177 (“nca-LuTATE”) and used it in over 30 administrations in NETs patients.
