#2852 Diagnostic Accuracy of Endoscopic Ultrasound-Fine Needle Aspiration (EUS-FNA) in the Evaluation of Pancreatic Neuroendocrine Neoplasms (PNEN) Grading
Introduction: Prognosis of pNENs depends on staging and grading, based on the cyto-histological Ki67 labelling; EUS-FNA is considered the gold standard technique to obtain it in pre-therapeutic setting

#3011 Added Prognostic Value of Molecular Imaging Biomarkers over Proliferation Index in Typical Lung Carcinoid: An FDG PET and SSTR Imaging Study
Introduction: Typical lung carcinoids(TCs)are rare tumors with good,although heterogeneous,prognosis.

#2841 Novelties in Primary and Metastatic GEP-NENs Clinical Outcome Investigation
Introduction: Gastro-entero-pancreatic neuroendocrine neoplasms (GEP-NENs) WHO classification, using strict cut-offs, should reflect their biological features. In real world, strict cut-offs not adequately segregate prognostic groups, in particular on metastasis (M).

#3036 Can Ki-67 with 5.5% Be Better in Predicting Prognosis for Well Differentiated Pancreatic Neuroendocrine Tumors?
Introduction: Pancreatic neuroendocrine tumors (NETs) are rare malignancies, Ki-67 is a cell proliferation marker that has been shown to have some utility in predicting prognosis of neuroendocrine tumors. However, the ideal grading method for G1/G2 remains controversial.

#3028 Pancreatic Neuroendocrine Neoplasms: Dissecting the Molecular Heterogeneity
Introduction: Pancreatic neuroendocrine neoplasms (PNENs) are a group of rare but biologically and clinically heterogeneous neoplasms with variable patient outcomes. Little is known about the molecular differences between PNENs and the biologic significance of such divergence.

#2831 Immunohistochemical Profile of Digestive Neuroendocrine Neoplasms: A Retrospective Analysis in a Single Algerian Institution
Introduction: Neuroendocrine Noplasms (NEN) are rare tumours, but their incidence is clearly increasing in our country due to the improvement of diagnostic means, in particular the generalization of immunohistochemical techniques. The digestive location represents more than 70% of the cases. The anatomopathological study enables to classify the NEN in different prognostic grades according to the degree of differentiation, mitotic index and Ki67.

#2883 Comparison of Somatostatin Analogues in Metastatic Gastroenteropancreatic Neuroendocrine Tumors from a Bayesian Perspective: The GETNE-TRASGU Study
Introduction: Somatostatin analogues (SSA), octreotide LAR (Oct) and lanreotide autogel (Lan), significantly prolong progression-free survival (PFS) in patients with well-differentiated gastroenteropancreatic neuroendocrine tumors (GEP-NET). However, comparative data are not available and randomized trials comparing both SSAs are unlikely to be conducted.

#2886 Risk Factors for Short Recurrence-Free Survivals after Resection of PanNET Liver Metastasis: Single Institutional Analysis
Introduction: Although the treatment of PanNEN has improved survivals with development of pharmacotherapy recently, surgery is the first choice if curative resection is expected to be achieved. However, most of the patients undergo recurrence after resection of the liver metastasis even after curative resection. Therefore, it is important to identify who gains longer RFS by resection.
