#2964 Personalized Therapy in a Case of Esophageal NEC Based on Tumor Genome Sequencing
Introduction: High-grade esophageal neuroendocrine carcinomas (NEC) constitute a rare subgroup of neuroendocrine neoplasms, with a particularly aggressive behaviour and unfavourable prognosis. To date, there are no validated biomarkers for personalized therapy and cytotoxic chemotherapy remains the standard of care. However, tumor genome sequencing may help improve NEC molecular landscape knowledge in order to identify novel targets for an individualized approach.

#2855 Whole Exome Sequencing Reveals the Monoclonal Origin of Gastric Mixed Adenoneuroendocrine Carcinomas
Introduction: Gastric mixed adenoneuroendocrine carcinomas (g-MANECs) are rare neoplasms consisting of adenocarcinoma and neuroendocrine neoplastic components. G-MANECs show more malignant characteristics than gastric adenocarcinomas, while molecular mechanisms underlying the co-existence of the two components remains unknown.

#2975 Next Generation Sequencing of Pancreatic Neuroendocrine Tumors in Russian Cohort
Introduction: The appearance of next generation sequencing (NGS), - a powerful high-performance method, allowed accumulation of a large amount of information concerning genetic and epigenetic patterns, however, the problem of matching clinical, histological picture with genetic structure in pNETs remains open.

#2781 Case Report: Whole Exon Sequencing of Primary Lesion and Metastatic Liver Lesion in Pancreatic Neuroendocrine Tumor
Introduction: Pancreatic neuroendocrine neoplasms(NENs) are classified into neuroendocrine tumors (NET) G1, G2, G3, and neuroendocrine carcinoma (NEC), which are different pathogenesis. The two kinds of tumors that occurs in the same lesion in one patient is very rare. We found high grade neuroendocrine neoplasms(NENG3) with a diameter of 0.1 cm in a patient with a pancreatic NETG2 (1.7 cm in diameter). The cells were significant atypia with Ki67 index of 60%, focal necrosis, while metastatic nodules in the liver (12, 0.1-1.1 cm in diameter) were all high grade NENG3.

#2896 Comparative Genomic Analysis of High Grade Neuroendocrine Neoplasms across Diverse Organs
Introduction: Grade 3 neuroendocrine neoplasms (G3 NENs), if poorly differentiated, have a median survival of 10-19 months. Little is known regarding biologic differences between G3 NENs from different primary sites, most commonly GI and lung.

#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.

#2861 Targeted Next Generation Sequencing Analysis Reveals the Genetic Characteristics of Gastric Neuroendocrine Neoplasmas
Introduction: there are abundant information about the clinical therapy and pathological features of gastric neuroendocrine neoplasms (gNENs) but little about its genetic characteristics.

#2827 Characterization of Epigenetic Modulation in Pancreatic Neuroendocrine Neoplasms
Introduction: Pancreatic neuroendocrine tumors (PanNETs) represent a rare and heterogeneous tumor entity. Despite advances in therapy cancer progression and resistance mechanisms are still challenging. Recent genome wide sequencing analyses in PanNETs identified a large number of mutated genes involved in epigenetic modulation.
