#21 Peptide Receptor Radioligand Therapy (PRRT) is an Effective Treatment for the Long-Term Stabilization of Malignant Gastrinomas
Introduction: Gastrinomas represent a rare group of neuroendocrine tumors usually located in the duodenum or pancreas. They secrete gastrin, which is responsible for the clinical picture of severe acid-related peptic disease and diarrhea, known as the Zollinger-Ellison syndrome (ZES). While symptomatic control may be achieved with proton-pump inhibitors (PPIs) and somatostatin analogues (SSAs) treatment, little data is known regarding the possible anti-tumor effect of the peptide receptor radioligand therapy (PRRT) in gastrinoma patients.

#38 Expression of mTOR signaling pathway and effects of mTOR inhibitors on its pathway in human neuroendocrine tumors
Introduction: Neuroendocrine tumors (NET), especially well-differentiated endocrine tumors, are often slow-growing, indolent, and may not become clinically apparent until the manifestations of metastatic spread or carcinoid syndrome. Results of previous studies demonstrated that phosphoinositide 3-kinase (PI3K)/Akt/mTOR signaling pathway may be activated in the great majority of NET cells. mTOR inhibitors are therefore considered effective anti-tumor reagents but they may also induce an activation of PI3K/Akt and MAPK pathways as a compensatory action and reduce their own anti-tumor activities.

#220 The Global mTOR Inhibitor Torin1 is More Effective than the mTORC1 Inhibitor, Everolimus, Alone or in Combination with Histone Deacetylases Inhibitors, in Suppressing Neuroendocrine Tumors Cell Proliferation
Introduction: Torin1, a new mTOR inhibitor that globally inhibits both mTORC1 and mTORC2, seems to impair cell growth and proliferation to a greater degree than rapamycin; its effects in NET cells are unknown.

#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.

#1875 Potential Anti-Tumor Activity of Biguanides and Statins in Neuroendocrine Tumor Cells
Introduction: Recent studies have suggested that biguanides and statins have beneficial effects on various cancer types; however, the precise effects and the molecular mechanisms underlying this pathophysiological association are still not well understood in neuroendocrine tumor (NETs).

#469 Cost-Effectiveness of Sunitinib in Patients with Advanced or Metastatic Pancreatic Neuroendocrine Tumors in Portugal
Introduction: Sunitinib is an oral multitargeted tyrosine kinase inhibitor approved in Europe in 2010 for use in well-differentiated pancreatic neuroendocrine tumors (pNET) that have spread or cannot be removed by surgery.

#514 Cost-Effectiveness of Sunitinib in Patients (Pts) with Advanced or Metastatic Pancreatic Neuroendocrine Tumors (pNET) in the Netherlands

#387 Combined Blockade of Several Signalling Pathways Shows Marked Anti-Tumor Potential in Two Novel Mouse Phaeochromocytoma Cell Lines
Introduction: The current study explores novel targeted therapies for malignant pheochromocytomas (PCCs) and paragangliomas, utilizing a more benign (MPC) and a more malignant (MTT) PCC cell line. We have previously shown that the dual PI3K/mTORC1 inhibitor NVP-BEZ235 significantly reduced MPC and MTT cell viability, but increased ERK signalling.

#972 Anti-Tumor Efficacy of Somatostatin Analogues (SSAs) in Patients with Neuroendocrine Tumors (NETs) According to Ki-67 Score: A Multicentric Study From ELIOS (Educational Learning Investigational Observational Study)
Introduction: SSAs have been demonstrated to have antiproliferative effects in ileal NETs. The 2010 WHO NET classification provides a grading score which can be helpful in predicting tumor response to SSA.

#2078 Self-Reported Side Effects in Neuroendocrine Tumor (NET) Patients Prescribed Somatostatin Analogues – The Role for Specialist Dietitians and Nurses
Introduction: In practice, many patients with NETs report a change in symptoms after starting somatostatin analogues (SSA’s). Many health professionals and NET patient advocates have noticed that some of the side effects experienced by patients are more common than patient information literature suggests. It is therefore important to ask what and how severe experiences are, and compare to literature, to help raise awareness amongst NET health professionals.
