#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.

#896 Grading of Metastases in Digestive Neuroendocrine Tumors (NET): Interest for Clinical Management?
Introduction: Therapeutic strategy of NETs is highly dependent on tumor classification according to the WHO system. NETs are frequently classified based on the histological characteristics of the primary tumor associated with the ENETS grading, even for patients with metastases.

#935 A Three Tier Grading System Based on Ki-67 Index, Mitotic Count and Necrosis with Cut-Offs Specifically Generated for Lung Neuroendocrine Tumors is Prognostically Effective and Accurate
Introduction: Lung neuroendocrine tumors are catalogued into four categories by the World Health Organization (WHO 2004) classification. Its reproducibility and prognostic efficacy was disputed. The WHO 2010 classification of digestive neuroendocrine neoplasms is based on a Ki-67 index and has proved prognostically effective.

#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).

#543 Endoscopic Ultrasound-Guided Fine Needle Tissue Acquisition (EUS-FNTA) Using a 19-G Needle for Histological Grading of Pancreatic Endocrine Tumors (PETs): A Prospective Study
Introduction: EUS-FNTA is increasingly used in the diagnosis of pancreatic endocrine tumors (PETs). Ki-67 expression, an important prognostic factor according to the WHO classification, is difficult to be determined on cytological specimens.

#696 Downgrading Due to Ki-67 Index Assessment with Image Analysis
Introduction: The latest WHO classification for neuroendocrine tumors (NET) defines their grade according to Ki-67 and mitotic index. These parameters have both shown to be prognostic.

#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.

#1789 FDG-PET is Superior to WHO Grading in Predicting Overall Survival of Patients with Neuroendocrine Tumors: A Prospective Study of 172 Patients
Introduction: Accurate grading of patients with neuroendocrine tumors (NETs) is essential for risk stratification and optimal choice of therapy. Currently, WHO grading is based on histo-pathologically assessed degree of tumor proliferation.
