#2741 Histologic Grading of Neuroendocrine Tumors and Its Relationship of Survival
Introduction: Current classification divides NENs into neuroendocrine tumors (NETs) and neuroendocrine carcinoma (NEC). NENs at different anatomic sites require site-specific applications for the classification.

#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

#2845 Primary Tumour Resection and PRRT of NEN Stage IV - Are There Differences in Grading?
Introduction: The resection of primary tumours (PT) in patients with stage IV NEN is still a matter of debate. The resection of tumours with a low proliferation index (G1/G2) is more accepted then the resection of high proliferative tumours (G3-NET / G3-NEC).

#2784 Predictive Factors of Tumor Recurrence after Radical Surgery for Gastro-Entero-Pancreatic Neuroendocrine Neoplasms (GEP-NENs): Identification of High-Risk Subgroups
Introduction: There is no proven role for adjuvant medical therapy after curative surgery (R0) for GEP-NENs.

#26 Molecular imaging of gastroenteropancreatic neuroendocrine tumours with Ga-68 DOTANOC PET/CT and correlation with an immunhistochemical quantification of somatostatin receptors using novel monoclonal and polyclonal antibodies
Introduction: Receptor PET/CT with somatostatin analogues marked with Gallium-68 (SMS-R-PET/CT) is currently the golden standard in diagnosing gastroenteropancreatic neuroendocrine tumors (GEP-NET), which are known for an overexpression of somatostatin receptors (SSTRs).

#126 Assessment of the proliferation marker Ki-67 by endoscopic ultrasound guided-Fine Needle Aspiration (EUS-FNA) in pancreatic endocrine tumors: A comparative analysis with histology of the surgical specimen
Introduction: Assessment of the proliferative index by Ki-67 immuno-labelling is an important prognostic parameter for the biologic behavior of digestive neuroendocrine tumors, usually established on the histological specimen obtained after surgery or macro-biopsy. However, small pancreatic endocrine tumors (PET) are more and more often recognized by CT/MRI and diagnosed by EUS. The value of Ki-67 labelling index (Ki-67-LI) on fine needle aspiration (FNA) is not well-established in this setting, although regularly assessed.

#134 Gastrointestinal neuroendocrine tumors: tumor characteristics and long-term clinical outcome in the German NET registry
Introduction: Prognosis of neuroendocrine tumors (NETs) has been difficult to predict due to heterogenous tumor biology, various classification systems, and lack of reliable and recent data due to the rarity of these tumors.

#213 Distinct Cut-Off Values of Ki-67-index for NET-Grading in a Large German Multicentrer Cohort
Introduction: Grading (G) of neuroendocrine tumors (NET) according to ENETS is based on immunhistochemical staining of Ki-67 antigen. Close margins between G1 and G2 NET often fail to differ in survival analysis.

#363 Clinicopathological characteristics are capable of predicting long-term outcome of gastrointestinal neuroendocrine tumours in Germany
Introduction: Neuroendocrine tumours (NET) are a rare and heterogeneous group of neoplasm. Throughout the last decades the classification of NET has been both difficult and incoherent. Therefore making prognostic straticifation often difficult.

#518 CK19 and KIT Immunostaining is a Useful Adjunct to Ki-67-Based Grading of Pancreatic NET: A Study on Matched Cytological and Histological Samples
Introduction: Pancreatic neuroendocrine tumors (NET) are rare neoplasms. Recent evidence suggests that Ki-67 staining predicts their behavior. Even more recently, a prognostic role has been proposed also for CK19 and KIT. This panel might guide patient management. CK19 and KIT have not yet been evaluated on NET on Fine needle aspiration samples (FNAs).
