#2870 When It Comes to the Diagnostic of Neuroendocrine Neoplasms (NEN), Not All Markers and Clones Were Made Equal. Assessment of 5 Makers in 466 NEN from 10 Anatomical Sites
Introduction: Histological diagnostic of neuroendocrine neoplasms (NEN) relies on morphological criteria and expression of several neuroendocrine marker assessed by immunohistochemistry. Systematic large evaluation of classical (chromogranin A (chrA), synaptophysin (Syn), CD56) and emerging (chromogranin B (chrB), INSM1) markers are lacking.

#2970 Characteristics, Treatments and Inflammatory Biomarkers in Patients (pts) with G3 Gastroenteropancreatic (GEP) Neuroendocrine Neoplasms (NENs)
Introduction: Well-differentiated neuroendocrine tumors G3 (NETsG3) pts have a different biological behavior compared to those with neuroendocrine carcinomas (NECs). Sensitivity to platinum depends on Ki67 and there is no standard second line (2L). Neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) are predictive factors of cancer survival, but with limited evidence in NENs.

#2967 Longitudinal Changes in Plasma 5-Hydroxyindoleacetic Acid (5-HIAA) and Other Biomarkers during Treatment of Functional Midgut Neuroendocrine Tumours (NETs) with Lanreotide Autogel: CALM NET Study Results
Introduction: CALM-NET (EudraCT 2013-002194-22; NCT02075606) evaluated pre-treatment circulating tumour cell levels in patients with NETs as a predictor of response to lanreotide autogel (LAN).

#2908 Re-Cellularised Human Pancreas 3D Scaffolds as a Novel Model for Biomarker Discovery in Pancreatic Neuroendocrine Tumours (pNETs)
Introduction: The lack of preclinical models of pNETs has challenged identification of tissue specific biomarkers of disease. Culturing cancer cells in their native tissue enables the close study of cell-ECM interaction and tissue remodelling. The biological products of such interactions can form a basis for discovery of novel biomarkers of the disease, and were previously linked with a range of inflammatory and malignant conditions.

#2689 Correlation between Immunohistochemical Markers Expression and Lymph Node Metastasis in Gastroenteropancreatic Neuroendocrine Neoplasms: A Nation-Wide 10-Year Retrospective Clinical Epidemiological Study in China
Introduction: Previous research on the correlation between different pathological features and the development of gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) is rare in China.

#2800 Thymosin Beta 4 Is an Autocrine Mitogen for Neuroendocrine Tumour Cells
Introduction: The most commonly used NET marker chromogranin A, has a sensitivity between 60-90% and a specificity of less than 50%, hence better NET markers are needed. Previous secretome analysis using BON1, NCI-H727 and SHP-77 cell lines has led to the discovery of various candidate NET markers. One such marker is Thymosin Beta 4 (TB4). TB4 is a small 43 amino acid intracellular peptide first isolated from bovine thymus tissue.TB4 or its oxidised form TB4SO are thought to play a role in various aspects of cancer biology including tumour invasion, metastasis and apoptosis.

#2707 Investigating the Crosstalk between MEN1, p53 and Notch Reveals Biomarkers of Formation of Primary Pancreatic Neuroendocrine Tumors
Introduction: Pancreatic neuroendocrine tumors (PNETs) comprise a heterogeneous group of endocrine tumors. Previous studies showed that mutations of p53 are extremely rare; whereas genetic changes of MEN1 frequently occur and are correlated with poor prognosis in PNET. Still, their roles in tumorigenesis remain elusive.

#2879 Lung Neuroendocrine Tumors: Experience of Medical Oncology Department of Hospital 1st November 1954 Oran
Introduction: Lung neuroendocrine tumors account for 25% of all neuroendocrine tumors. It is a heterogeneous group that meets morphological criteria; immunohistochemical and molecular; defining 4 groups: Typical and atypical carcinoid tumors, neuroendocrine carcinomas with large cell and small cells. Carcinoid syndrome is rare in these tumors and the treatment is based on surgery for localized forms and multimodal treatment for metastatic forms.

#2934 Vasostatin-1 Predicts Recurrence in Patients Submitted to Surgery for Nonfunctioning Pancreatic Neuroendocrine Tumors (NF-PanNET)
Introduction: An association between preoperative Vasostatin-1 (VS-1) plasma level and pathological features of aggressiveness was previously reported in patients with surgically resected nonfunctioning (NF) PanNET.

#3026 IMP3 and Ki-67-Factors of Poor Clinical Outcome in Neuroendocrine Tumors of the Lung
Introduction: Insulin- like growth factor-II messenger RNA- binding protein- 3 (IMP3) is often detected in malignant neoplasm of different sites. Ki-67 proliferative index, although helpful in diagnosing neuroendocrine tumours of lung, has not been recognised as prognostic factor.
