#246 SDHB Loss Predicts Malignancy in Pheochromocytomas/Sympathethic Paragangliomas, but Not Through Hypoxia Signalling
Introduction: To date there is no reliable histopathological marker of malignancy for pheochromocytomas/sympathetic paragangliomas (PCC/PGL). It is well-known that PCC/PGL in the hereditary context of an SDHB germline mutation very often metastasize. The immunohistochemical loss of SDHB expression was recently shown to be a surrogate marker for the presence of an SDH germline mutation in PCC/PGL. SDHB loss is supposed to be tumorigenic via activation of hypoxia signals.

#981 Parathyroid Hormone-Related Peptide (PTHrP) Secretion by Metastatic Gastroenteropancreatic Neuroendocrine Tumors (GEP-NET): Clinical Features, Diagnosis, Management, and Long-Term Follow-Up
Introduction: There are a few large series of patients with parathyroid hormone (PTH)-related protein (PTHrP) secreting neuroendocrine tumors (NETs) causing severe hypercalcemia.

#1677 A New Scoring System to Predict Recurrent Disease in Grade 1 and 2 Non-Functional Pancreatic Neuroendocrine Tumors.
Introduction: Surgical resection is the preferred treatment for NF-pNET, however recurrence still occurs frequently after curative surgery, worsening prognosis of patients.

#360 High Resolution (Epi)genomic Analysis Comparing Pulmonary Carcinoids with a Favorable and a Poor Disease Outcome
Introduction: Lung carcinoids are a heterogenous group of neuroendocrine tumors. MEN1 mutations and 11q22-q25 deletions have been implied in their tumorigenesis. Very few genome wide and methylation studies have been conducted to further elucidate molecular mechanisms underlying tumorigenesis.

#462 Genome-Wide Expression Profiling Reveals Downregulation of OTP and CD44 and Upregulation of RET as Indicators of Poor Prognosis in Lung Carcinoids
Introduction: Lung carcinoids comprise a heterogeneous group of neuroendocrine tumors. Only few parameters have been identified that correlated with poor disease outcome, including 11q22-q25 deletions. New biomarkers are required to further improve diagnosis and prediction of prognosis.

#654 Identification of Signaling Pathways Involved in Lung Carcinoid Progression Using Gene Expression Profiling
Introduction: Lung carcinoids are well-differentiated neuroendocrine tumors (NETs) usually associated with a favorable prognosis. Mechanisms underlying progression are poorly understood.

#1050 Recurrent Disease After Curative Pancreatic Resection for Patients with Non-Functional Neuroendocrine Tumor; Identify the High Risk Patient
Introduction: Since the overall favourable survival, detection of recurrent disease is one of the main goals during follow up in patients with resected pancreatic neuroendocrine tumors (pNET).

#2847 Surgical and Survival Outcomes of Early Peptide Receptor Radionuclide Therapy for Downstaging Locally Advanced or Oligometastatic Pancreatic Neuroendocrine Neoplasms
Introduction: Pancreatic neuroendocrine neoplasm (pNEN) patients often present with locally advanced or metastatic disease. The objective response rate of peptide receptor radionuclide therapy (PRRT) in pNENs is 55%. Therefore, PRRT may be a possibility for patients who are not eligible for upfront curative surgery.

#3045 Reliability and Agreement of Radiological and Pathological Tumor Size in Patients with MEN1-Related Pancreatic Neuroendocrine Tumors: Results from a Population-Based Cohort
Introduction: Pancreatic neuroendocrine tumors (pNETs) are the most lethal manifestation in patients with multiple endocrine neoplasia type 1 (MEN1). Tumor size is still regarded as the main prognostic factor and therefore used for surgical decision making.

#153 Antibody formation against somatostatin analogues with altered biodistribution and dosimetry: a case with implications for PRRT
Introduction: Peptide receptor radionuclide therapy (PRRT) of neuroendocrine tumors (NETs) has emerged as a powerful palliative therapy. I.v. administration of radiolabeled (e.g. Yttrium-90) somatostatin analogues (SA) results in high-dose local irradiation of all tumor sites. The radiolabelled SA accumulates in the tumors through receptor-mediated internalization depending on the expression of somatostatin receptors and the pharmacokinetics of the radiolabelled SA.
