#2803 Chromogranin A as a Tumoral Marker for Neuroendocrine Tumors in Chilean Patients: A Case-Control Study
Introduction: Neuroendocrine tumors (NETs) are highly heterogeneous, serum chromogranin A (CgA) has a 60-100% of sensitivity and 68-100% of specificity with a cutoff value of 108 ng/mL as a marker for diagnosis of NETs.

#3022 Diagnostic Accuracy of 68Gallium Positron Emission Tomography (68Ga PET), Endoscopic Ultrasound (EUS) and Computed Tomography in the Assessment of Lymphnode Metastases by Nonfunctioning Pancreatic Neuroendocrine Neoplasms
Introduction: The presence of nodal metastasis is one of the most important predictive factors for recurrence after radical surgery for nonfunctioning Pancreatic Neuroendocrine Neoplasms (NF-PanNEN). Nevertheless, it is not clear which is the best diagnostic examination to identify preoperatively lymphnodal metastasis.

#2706 A New Possibility in SI-NET Surgery by Using a New β- Probe and 90Y-DOTATOC: A Pilot Study
Introduction: In neuroendocrine tumor (NET), complete surgery could better the prognosis of this disease: radioguided surgery (RGS) with beta-radioisotopes, as 90Y, is a novel approach focused on developing a new probe which, detecting electrons and operating with low background, provides a clearer delineation of the margins of lesions with low radiation exposition for surgeons.

#2717 64Cu-DOTATATE PET/CT Predicts Progression-Free Survival in Patients with Neuroendocrine Neoplasms
Introduction: The degree of overexpression of somatostatin receptors in patients with neuroendocrine neoplasms (NEN) may reflect tumor differentiation and thus be associated with prognosis. Non-invasive quantification of receptor density is possible by somatostatin receptor imaging (SRI) using positron emission tomography (PET).

#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.

#2805 Small Bowel Neuroendocrine Tumor Metastases: Comparison of Contrast-Enhanced Computed Tomography and 68Ga-DOTATATE PET/CT
Introduction: Most gastrointestinal neuroendocrine tumors (GI-NETs) involve the small intestine (38%) and about 50% of patients present with regional or distant metastases at time of diagnosis [2]. 68Ga-DOTATATE PET/CT provides improved sensitivity and specificity compared to traditional nuclear medicine techniques [4]. However, there is relatively less data comparing performance of 68Ga-DOTATATE PET/CT with contrast-enhanced CT (CECT).

#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.

#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.
