#271 A Novel Missense Mutation of the TMEM127 Gene that Leads to Pheochromocytoma Phenotype
Introduction: Recently, truncating germline mutations in TMEM127 gene have been identified in 30% of familial cases of adrenal pheochromocytoma (PHEO) and in 3% of apparently sporadic cases.

#1884 Towards Optimal Personalized Diet and Vitamin Supplementation in NET Patients; A Feasibility Study
Introduction: Patients with a neuroendocrine tumor (NET) often have gastro-intestinal complaints due to somatostatin analogue (SSA), tumor mass, secretion of neuroendocrine amines or treatment. This can lead to impaired absorption of critical food components such as vitamins. Serotonin producing NET patients may also have low plasma tryptophan.

#209 A Randomized, Cross-Over Study in Patients with Neuroendocrine Tumors (NETs) to Assess Patient Preference of Lanreotide Autogel Given by Either Self/Partner or Healthcare Professional
Introduction: Ready-to-use Lanreotide Autogel provides the option of self/partner administration for patients with NET. This is anticipated to reduce treatment cost and negative impact on daily life.

#319 Expression of EGFR and IGF Pathway Genes in Insulinomas
Introduction: Anti-epidermal growth factor receptor (EGFR) therapy has been suggested in patients with inoperable/progressive endocrine pancreatic tumors (EPTs). However, various % EGFR-expressing EPTs are reported.

#670 The Relationship Between the Ki-67 Protein and IGF-Related Genes in Gastroenteropancreatic Neuroendocrine Tumor Patients with Normal and Elevated Serum Chromogranin-A
Introduction: GEP-NETs are rare, heterogeneous neoplasms with a distinct biological and clinical behavior. Both IGF-system and Ki-67 indices have been reported as important stimulating factors in carcinogenesis and/or tumor progression. The tumor marker CgA is an independent predictor for survival as well. Currently no data are available about a possible interaction between IGF-system (IGF(-R)s, IRs, BPs) and Ki-67 protein in GEP-NET patients with normal and elevated serum CgA.

#737 Impact of Ki-67 Proliferative Index on Survival in Patients with Typical and Atypical Pulmonary Carcinoids
Introduction: Currently pulmonary carcinoids are separated into typical and atypical tumors based on mitotic count and presence of necrosis, according to the WHO classification. Whereas for GEP NETs the ENETS Guidelines have been incorporated into the WHO classification and grading is based on mitotic counts and Ki-67 index, the use of the Ki-67 index for grading pulmonary carcinoids is still under debate.

#850 Expression of IGF/mTOR Pathway Components in Human Pheochromocytomas and In Vitro Inhibition of PC12 rat Pheochromocytoma Cell Growth by mTOR Inhibitors alone and in Combination with the Dual IGFI-R/INS-R Antagonist OSI-906
Introduction: Dysregulation of the mTOR and IGF pathways have been suggested to be involved in the pathogenesis of pheochromocytomas (PCC). mTOR inhibitors, such as sirolimus (S) and everolimus (E), as well as IGFI-R antagonists such as OSI-906, could be new a treatment for malignant PPC.

#1099 Niacin (vitamin B3) Suppletion in Patients with Serotonin Producing Neuroendocrine Tumors
Introduction: Tryptophan is the precursor of serotonin and niacin (vitamin B3), critical for normal cellular metabolism. Tryptophan and niacin can be deficient in patients with serotonin producing neuroendocrine tumors (NETs). Niacin deficiency can lead to symptoms including pellagra.

#1150 Platelet Serotonin But Not Dopamine Concentrations Are Lower in Pancreatic Neuroendocrine Tumor and Renal Cell Carcinoma Patients Compared to Healthy Individuals.
Introduction: Platelets carry VEGF-A, serotonin and dopamine. Serotonin stimulates and dopamine inhibits tumor angiogenesis. We hypothesized that platelets are activated in tumor vasculature and release angiogenic factors, resulting in lower platelet serotonin and dopamine.
