#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.

#2731 177Lu-DOTATATE Plus 166Ho-Radioembolization in Patients with Neuroendocrine Tumours; A Single Center, Prospective, Interventional, Non-Comparative, Open Label, Phase II Study (HEPAR PLuS Study)
Introduction: The liver is the most commonly affected organ in metastatic neuroendocrine disease and is the most incriminating factor for patient survival. Additional treatment of liver disease with radioembolization may improve outcome in NET patients with bulky residual liver disease after PRRT.

#2913 The Predictive Value of Neuroendocrine Transcript Analysis in Daily Practice: An Independent ‘Real-World’ Validation Study
Introduction: Assessment of disease status remains the fundamental basis in the management of gastro-entero-pancreatic neuro-endocrine tumors (GEPNETs). Circulating molecular information might be used as a liquid biopsy to predict its clinical course.

#2999 Aberrant Tryptophan Metabolism in Stromal Cells Is Associated with Mesenteric Fibrosis in Small Intestinal Neuroendocrine Tumours
Introduction: Increased levels of serotonin secretion are associated with mesenteric fibrosis (MF) in small intestinal neuroendocrine tumors (SI-NETs). However, only a proportion of patients with increased serotonin production will develop mesenteric fibrosis.

#2982 Comprehensive Molecular Analysis Identifies Driver Mutations in Metastases of Sporadic Well-Differentiated Neuroendocrine Tumours of the Small Intestine
Introduction: Small intestinal neuroendocrine tumours (SI-NETs) represent a heterogenous group of tumours. The molecular mechanisms which contribute to progression of SI-NETs are poorly elucidated. They are considered to be molecularly distinct from neuroendocrine carcinomas (NECs), which share oncogenic pathways with adenocarcinomas.

#2849 PRRT Neuroendocrine Tumor Response Assessment Using Circulating Transcript Analysis: The NETest
Introduction: The absence of an accurate blood biomarker to predict and monitor PRRT is a key unmet need.

#2905 DNA Methyltransferase Inhibitor Hydralazine Induces Upregulation of Somatostatin Type 2 Receptors in Human Neuroendocrine Tumor Cells
Introduction: Epidrugs like DNA methyltransferase inhibitors (DNMTi) can increase somatostatin receptor type 2 (SST2) expression in neuroendocrine tumor (NET) cells in vitro and in vivo. This effect could be used for NET patients with low SST2 expression who are currently ineligible for somatostatin analogue (SSA) treatment. However, the DNMTi known to stimulate SST2 have either a high toxicity profile or are not yet approved.

#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.

#65 Deletions of 11q21-q25 are associated with atypical lung carcinoids and a poor clinical outcome
Introduction: Lung carcinoids comprise a group of smoking-unrelated neuroendocrine tumors, which can be classified in typical (TC) and atypical (AC) carcinoids. Classification is complex and its accuracy to predict disease outcome is variable. In a previous array comparative genomic hybridization (arrayCGH) study, we showed that the average number of chromosomal alterations (≥ 1Mb) was significantly higher in ACs than in TCs (512 v. 226 per tumor) and that the most common region of chromosome loss was 11q21-q25 (Neuroendocrinology 2009;90:136-137).

#83 Surgical treatment of duodenopancreatic neuroendocrine tumors (pNETs) in patients with multiple endocrine neoplasia type 1 (MEN 1): a Dutch consensus statement
Introduction: Duodenopancreatic neuroendocrine tumors (pNETs) in multiple endocrine neoplasia type 1 (MEN 1) are the most important cause of MEN 1-related death. Surgery is the only curative treatment, but controversy exists on the optimal strategy. Recent guidelines on pNETs have limited recommendations specific for MEN 1. Therefore, a Dutch multidisciplinary consensus meeting was organized.
