#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.

#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.

#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.

#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.

#774 The Grading of pNENs in MEN-1 Syndrome: Consequences for Tumor Progression and Surgical Strategy?
Introduction: MEN-1 patients develop multiple pNENs. The treatment of choice ranges from watchful waiting to total pancreatectomy. Up to now, the impact of the grading has not been evaluated to either plan surgery or conservative treatment.

#859 Pancreatic Neuroendocrine Tumors (PNETs): Role of Endoscopic UltraSound-Fine Needle Aspiration (EUS-FNA) and Accuracy of Ki-67 Measurement on Cytological Specimens
Introduction: The role of EUS-FNA in preoperative diagnosis and grading of pNETs is well-established, but it is unclear how Ki-67 expression on cytological specimens obtained by EUS-FNA reflects the value found on surgical specimens.
