#2909 Serotonin-Secreting NeuroEndocrine Neoplasms of the Pancreas: Which Are the Primary Pancreatic Carcinoids?
Introduction: Serotonin-secreting pancreatic neuroendocrine neoplasms (5-HT-secreting pNENs) are very rare. They are characterised by high urinary 5-hydroxyindole-acetic acid (5-HIAA) levels (or high serum 5-HT levels).

#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.

#2750 Progression-Free Survival and Clinical Outcomes with Long-Term Use of Telotristat Ethyl in US Clinical Practice
Introduction: Treatment of advanced neuroendocrine tumors aims to relieve symptoms and suppress tumor growth. Primary findings from the TELEACE study suggested telotristat ethyl (TE) may reduce tumor size and impact tumor growth.

#3075 Telotristat Makes Significant Difference on Symptoms and Serotonin Levels in a Population with Widespread GI-NET and Severe Carcinoid Syndrome
Introduction: In spite of new treatments like PRRT or everolimus there is a clinical need for systemic therapies that complement SSAs (somatostatin analogs) and antidiarrheal agents in the treatment of carcinoid syndrome, a late stage problem in s-i-NET. Telotristat is a promising addition to our therapeutic arsenal.

#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.

#2772 Vitamin Supplementation and a Personalized Diet in Patients with Neuroendocrine Tumors: The DIVIT Study
Introduction: Patients with neuroendocrine tumors (NETs) are at risk for vitamin deficiencies and poor nutritional status due to excessive serotonin production, diarrhea, previous gastrointestinal surgery, and/or treatment with somatostatin analogues (SSA). Little knowledge exists about vitamin deficiency and how patients should be supported for the deficiencies they develop during their long-lasting disease.

#2840 A Real-World Study of Patients with Carcinoid Syndrome at King’s College Hospital on Long-Term Telotristat Therapy
Introduction: Telotristat ethyl is a tryptophan hydroxylase inhibitor that has been shown to be effective against symptoms of carcinoid syndrome refractory to standard somatostatin analogue therapy by directly inhibiting serotonin production. While clinical trials have established short-term efficacy of the drug, we report an exploratory real-world study of 15 patients with metastatic neuroendocrine tumours on long-term Telotristat (median duration=8 months).

#2867 Experience of Treatment with Everolimus in Patients with Well-Differentiated Neuroendocrine Tumors (NET) of Various Localizations at the NN Blokhin NMRCO, Moscow, Russia
Introduction: Everolimus (EVE) (mTOR inhibitor) is an effective drug in the treatment of well-differentiated NETs of different localizations, however, prognostic factors for the correct choice of therapy are not well understood.

#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

#12 Chromogranin A as a predictor of progression, regression or stable disease in ileo-cecal (midgut) carcinoid tumors
Introduction: A general characteristic for NETs is their expression of certain proteins, such as chromogranin A (CgA), which is released from the dense core vesicles of NE cells, occasionally together with cell specific hormones, such as gastrin and serotonin. Plasma CgA seems to be closely related to tumor burden of intestinal carcinoid tumors in humans.
