#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).

#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.

#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.

#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.

#1638 3D Primary Cell Culture: A New Promising Preclinical Model for Pancreatic Neuro-Endocrine Tumors (pNETs).
Introduction: The lack of adequate in vitro and in vivo preclinical models has hampered the identification of novel treatment options and the development of personalized therapy selection for pNET patients.

#336 Overall Survival (OS) Analysis of Sunitinib (SU) After Adjustment for Crossover (CO) in Patients With Pancreatic Neuroendocrine Tumors (NET)
Introduction: A recent phase 3 trial of SU in pancreatic NET showed an improvement in progression-free survival (PFS) and OS. However, the OS benefit was confounded by early CO from placebo (PBO) to SU treatment.

#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.

#1867 Establishment of the First Well-Differentiated in Vivo Human Pancreatic Neuroendocrine Tumor Model
Introduction: The development of new therapeutic strategies for cancer patients relies on the in vitro and in vivo testing of novel substances in the pre-clinical setting. So far, this has not been possible for pancreatic neuroendocrine tumors (pNET) due to lack of suitable animal models resembling the disease course in human patients.

#2081 Preclinical Testing of SSA Compounds in a Model of Pancreatic Neuroendocrine Tumors to Optimize Scheduling and Drug Exposition
Introduction: Somatostatin analogues (SSA) such as Octreotide and Lanreotide have demonstrated a significant benefit in Neuroendocrine Tumors, particularly in the well/moderately differentiated types. Nevertheless, there are still several aspects of SSA treatments that remain unsolved, such as drug exposition in patients and schedule optimization.

#2126 Histone Replacement in Cancer: Dissecting the Role of H3.3 Chaperones in Pancreatic Tumorigenesis
Introduction: Cancer driver mutations affecting the histone H3.3 chromatin remodellers ATRX and DAXX were recently discovered in 43% of sporadic pancreatic neuroendocrine tumours (PNET). Progressive age-dependent replacement of canonical H3.1/2 with H3.3 is crucial for maintaining genome integrity through expression of repressive markers at heterochromatic sites, where loading is mediated by ATRX and DAXX. Loss of H3.3 chaperones in PNET is associated with activation of ALT, a telomere maintenance mechanism, eventually leading to chromosome instability. It has been suggested that ATRX/DAXX expression is necessary for repressing ALT, but mechanistic details of this interaction are not fully understood.
