#2144 Analysis of the Proteomics of Serum Circulating Exosomes in Gastro-Entero-Pancreatic Neuroendocrine Neoplasms
Introduction: Gastro-entero-pancreatic neuroendocrine neoplasms(GEP-NENs) are intractable, heterogeneous tumors, characterized by secreting serotonin metabolites or polypeptide hormones. There are currently little targets for the diagnosis and treatment of GEP-NENs. Serum circulating exosomes (scrExos) are extracellular vesicles secreted by all cells especially neuroendocrine cells to some extent, circulating in the blood with proteins and nucleic acids.

#2173 Decreased Serum Amyloid A1 as Potential Diagnostic Marker for Gastro-Entero-Pancreatic Neuroendocrine Neoplasms
Introduction: Gastro-entero-pancreatic neuroendocrine neoplasms (GEP-NENs) are rare tumors with an increased incidence reported in recent years. Researchers have shown that tumor cells produce and secrete more exosomes compared with normal cells. Serum amyloid A1 (SAA1) is elevated in patients with liver cancer, lung cancer, breast cancer, prostate cancer and endometrial cancer. However, the relation between SAA1 and GEP-NENs remains unclear.

#88 EpCam expression and detection of circulating tumor cells in neuroendocrine tumors
Introduction: Using the CellSearchTM system, circulating tumor cells (CTCs) can be reproducibly enumerated according to expression of EpCAM and cytokeratins 8, 18 or 19 and the absence of the haemopoietic marker CD45. The number of CTCs detected in 7.5 mls blood has been shown to correlate with prognosis in breast, colon and prostate cancer and can predict response to therapy. Neuroendocrine tumors (NETs) have not previously been reported to express EpCAM and have not been systematically assessed for presence of CTCs. We have therefore explored the expression of EpCAM in NETs and the detection of NET cells in the circulation.

#1642 Angiogenic Circulating Biomarkers in Patients with Advanced Pancreatic Neuroendocrine Tumors Treated with Everolimus
Introduction: More than 10% of patient treated with Everolimus develop early onset of resistance. The lacking of adequate predictive factors in the targeted hera makes challenging the early identification of non-responders patients.

#674 Serum miRNA Expression in Small Intestine Neuroendocrine Tumors and Biological Function of miR-196a in Neuroendocrine Tumor Cells
Introduction: MicroRNAs (miRNAs), post-transcriptional regulators, function either as tumor suppressors or oncogenes. We recently identified five upregulated and four downregulated miRNAs in small intestinal neuroendocrine tumor (SI-NET) tissue. We then started new analysis on body fluids to detect tumor signatures using patients’ serum.

#807 MicroRNA Expression in Serum of Small Intestine Neuroendocrine Tumor Patients and miR-196a Biological Function in Neuroendocrine Tumor Cells
Introduction: We have previously identified five upregulated and four downregulated miRNAs in small intestinal neuroendocrine tumor (SI-NET) tissue. We extended our analysis to serum samples of SI-NET patients to depict miRNAs functions.

#498 Limitations of Chromogranin A in Clinical Practice
Introduction: Chromogranin-A (CgA) is the most accurate marker for the histological diagnosis of neuroendocrine tumors (NETs). However diagnostic usefulness of circulating CgA is controversial as several conditions, both neoplastic and non-neoplastic, may induce false positive increases of this marker.

#727 Serum Levels of Chromogranin A Were Not Elevated in Patients with Insulinomas
Introduction: According to ENETS and NANETS Consensus Guidelines, Chromogranin A (CgA) is the most practical and useful serum tumor marker in NET patients (pts), including pancreatic NETs. Many studies suggested that test of blood CgA should be mandatory for NET diagnosis.

#616 Assessment of DNA Double-Strand Breaks in Blood Lymphocytes after Whole-Body Radiation Exposure in Patients with Neuroendocrine Tumors Undergoing 177Lu-Octreotate Therapy
Introduction: Peptide receptor radionuclide therapy using somatostatin receptor-binding peptides, such as 177Lu-Octreotate (LuTate), has been clinically proven to be effective in treating patients with inoperable neuroendocrine tumors. Despite the rather high radiation exposure, only few side effects have been reported. However, blood cells are very sensitive to radiation. Therefore, it is important to determine how much radiation they received. Recently, the detection by immunofluorescence of the phosphorylation of the histone variant H2AX (γ‐H2AX) has been established as a reliable and sensitive technique to monitor DNA double-strand breaks (DSBs) in blood lymphocytes.

#2000 A Case of Multiple Endocrine Neoplasia Type 2B(MEN2B)
Introduction: Familial neuroendocrine neoplasms (NENs) accounts for less than 5% of NENs and multiple endocrine neoplasia type 2B (MEN2B) is a kind of rare familial NENs.
