#3031 Primitive Peripheral Neuroectodermal Tumor: Case Report
Introduction: Primitive neuroectodermal tumors belong to the family of Ewing sarcomatous tumors, all derived from the same stem cell. The cells of the neural crest are believed to be at the origin of these tumors. The predilection sites of these sarcomas are para-vertebral region, chest wall and the distal ends. The positive diagnosis of primary neuroectodermal tumors requires the contribution of histopathology, immunohistochemistry and cytogenetics.

#2801 IMMUNeOCT: OCT LAR in the Induction of Immunologic Response in Patients with Neuroendocrine Neoplasms (NENs): A Perspective Observational and Translational Study (EudraCT2017-001613-83)
Introduction: The possible impact of octreotide (OCT) Long-Acting Release (LAR) on the immune system regulation is largely unexplored.

#2690 Marked Response to Nab-Paclitaxel in Advanced Neuroendocrine Carcinoma of Nasal Sinuses: A Case Report
Introduction: Sinonasal neuroendocrine carcinomas (SNECs) are a very rare and high-grade malignant epithelial neoplasm that is usually associated with a poor prognosis.

#2692 Development of Ex-Vivo Models of Metastatic Neuroendocrine Neoplasms
Introduction: The lack of relevant in-vivo and in-vitro models has precluded investigations of the pathophysiology of metastatic NENs. Organotypic tumour slices retain the complexity of tumours in-vivo without extensive manipulation of the tissue.

#2745 Integrative Genomic Characterization Identifies Molecular Subtypes of Lung Carcinoids
Introduction: Lung carcinoids (LCs) are rare and slow growing primary lung neuroendocrine tumors. The WHO classify LCs into atypical and typical carcinoids. Recent studies have shown that the reproducibility of LCs classification and its prognostic efficacy have high interobserver variability

#2810 Development of a Personalized Human Immunocompetent Ex-Vivo Model of Neuroendocrine Liver Metastasis Using Precision Cut Tissue Slice Technology
Introduction: Liver metastasis (LM) are very frequent (65-95%) and represent a crucial prognostic factor in patients with gastroenteropancreatic neuroendocrine neoplasms (GEP NENs). The paucity of relevant experimental models has limited the understanding of the pathophysiology of NENs and the development of efficient therapeutic strategies

#122 Molecular genetic findings in gastric carcinoid suggest possible neurofibromin/Ras pathway involvement in carcinoid pathogenesis
Introduction: The molecular pathogenesis of gastrointestinal carcinoid tumours is poorly understood. We have been undertaking molecular genetic investigations of a young woman with neurofibromatosis type 1 (NF1) in whom a gastric carcinoid tumor was detected following an episode of gastrointestinal bleeding. She was otherwise relatively mildly affected by NF1. In NF1, gastric carcinoids have been found previously only in patients with other predisposing factors, which were absent in this patient.

#270 Insulinoma: A Rare Tumor?
Introduction: Insulinoma, a pancreatic ß-cell tumor, comprises 55% of neuroendocrine tumors with an annual incidence of 3-10/million. 10% are malignant, 10% are multiple and half of them present in MEN-1.

#394 Efficacy of Telotristat Etiprate in Refractory Carcinoid Syndrome: Results of a Randomized, Placebo-controlled, Multicenter Study
Introduction: Diarrhea associated with carcinoid syndrome (CS) has been attributed to excess serotonin. Telotristat etiprate is an oral serotonin synthesis inhibitor that decreases peripheral serotonin production.

#396 Telotristat Etiprate Produces Clinical and Biochemical Responses in Patients with Symptomatic Carcinoid Syndrome: Preliminary Results of an Ongoing Phase 2, Multicenter, Open-label, Serial-ascending, European Study
Introduction: Excess serotonin (5-HT) may cause gastrointestinal (GI) symptoms (e.g., diarrhea) in carcinoid syndrome (CS) patients. Telotristat etiprate is an oral serotonin synthesis inhibitor designed to reduce peripheral 5-HT levels and alleviate GI distress.
