#2984 AGTR1 Is Overexpressed in Neuroendocrine Neoplasms, Regulates Secretion and May Serve as a Target for Molecular Imaging and Therapy

Introduction: Peptide receptor targeting has proven to be a pivotal tool for diagnostic imaging and radioligand therapy of neuroendocrine neoplasms (NENs), which frequently express somatostatin receptors (SSTRs) on their cell surface. However, up to 30 % of NEN patients do not benefit from SSTR-based approaches, others develop a resistance.

#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.

#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.

#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.

#2275 Analysis of Gene Expression Patterns of Rectum Neuroendocrine Tumors (NET) Versus Healthy Tissue Reveals Alterations in the MAPK and WNT Signaling Pathways

Introduction: The neuroendocrine tumors (NETs) of the rectum are rare but increasing in incidence, by means of improved endoscopic techniques and histological reporting. They often occur as small polypoid lesions and G1, and in most cases an incidental finding at endoscopy.
