#2712 HORMONET: Study of Tamoxifen in Well Differentiated Neuroendocrine Tumors (NET) and Hormone Receptor Positive Expression
Introduction: We have shown immunohistochemistry (IHC) expression of estrogen (ER) and progesterone receptors (PR) in 20.8% and 18.8% of 96 NET patients (pts). An old clinical trial (Mortel C, 1984) suggested antitumor effects of estrogen/progesterone-directed therapies in NET. Yet the effects of an antiestrogen agent in NET pts whose tumor express ER and/or PR are unknown.

#2746 Immunohistochemical Biomarker Expression in Gastro-Entero-Pancreatic Neuroendocrine Tumors at ENETS Centre of Excellence, University Hospital Zurich, Switzerland
Introduction: Gastro-entero-pancreatic neuroendocrine tumors (GEP-NET) are a heterogeneous tumor entity with respect to biological behaviour and prognosis. This makes diagnosis and treatment a major challenge.

#3071 Hormonal Ectopic Secretion Syndromes Associated to Neuroendocine Neoplasia
Introduction: Neuroendocrine neoplasias (NEN) are able to produce and secrete bioactive peptides and cause distinct syndromes related to their biological effects. The outcome will depend on the oncological disease as well as the hormonal syndrome

#2739 Epigenetic Landscape of Pancreatic Neuro-Endocrine Tumors Reveals Distinct Cells of Origin and Means of Tumor Progression
Introduction: Pancreatic Neuroendocrine Tumors (PanNETs) arise from cells of the Islets of Langerhans. The majority of PanNETs are non-functional and their cell of origin cannot be defined analysing specific hormone production. Cell of origin assessment has proven importance to identify risk factors, prevent tumour development, and tailor treatment in many malignancies. Recent data on super-enhancer signatures has suggested a potential origin of PanNET from α- or β-cells. We and others have shown that distinct epigenetic profiles assessed by DNA methylation (DNAme) characterize genomic and prognostic groups of PanNET.

#2775 Glucagonoma: Still a Misleading Disease and the Importance of Multidisciplinary Neuroendocrine Tumor Board
Introduction: Glucagonoma is a rare neuroendocrine tumor (NET) of the pancreatic alpha cells that results in the overproduction of the hormone glucagon. This entity is typically associated with a rash called necrolytic migratory erythema, weight loss and diabetes.

#2833 Surgical Correction of Carcinoid Heart Disease Improves Liver Function and 5-Hydroxyindoleacetic Acid Levels
Introduction: Neuroendocrine tumours of the gastrointestinal tract cause carcinoid syndrome and carcinoid heart disease. These tumours secrete serotonin, which can bind to heart valves and cause fibrosis and valve incompetence. Most cases involve the tricuspid valve +/- pulmonary valve. Medical management comprises diuretics for fluid overload and somatostatin analogues to reduce circulating serotonin. Definitive treatment is heart-valve replacement surgery which improves exercise tolerance but has high perioperative mortality. We have previously reported that valve-replacement surgery can reduce 5-hydroxyindoleacetic acid (5-HIAA) levels, reflecting a decline in hormone activity.

#2954 Aggressive Resection - A Treatment Option in Patients with Advanced Neuroendocrine Tumors
Introduction: Different treatment modalities have been considered for patients with malignant advanced neuroendocrine tumors(NETs) of the pancreas and duodenum.Aggressive surgery remains a controversial yet an efficacious antitumor therapy.

#2958 The Blood-based Multigenomic NETest Accurately Identifies Neuroendocrine Transformed Prostate Cancer
Introduction: Neuroendocrine differentiation and an aggressive phenotype is an important feature of castration-resistant prostate cancer (CRPC). Current biomarkers are unable to detect these advanced, treatment refractory variants.
