#955 Usefulness of the WHO Classification and of the ENETS TNM Staging System to Predict Prognosis in Patients with Rectal NENs
Introduction: WHO classification and TNM staging system have been proposed for rectal neuroendocrine neoplasia (NENs). However, their prognostic accuracy is not validated yet.

#1239 Histological Classification of Pancreatic Neuroendocrine Tumours: Optimising the Ki67 System
Introduction: Pancreatic neuroendocrine tumours are graded using the Ki67 antigen in accordance with the WHO 2010 classification. Despite the system’s widespread use, a wide variety of tumour behaviours have been described leading to various proposed revisions.

#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.

#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.

#2248 High Grade (G3) Gastro-Entero-Pancreatic Neuroendocrine Neoplasms: Should the New WHO Classification Apply to All?
Introduction: Grade 3 (G3) neuroendocrine neoplasms (NEN), arising from the gastro-entero-pancreatic system (GEP), are classified according to WHO 2010 and defined as having a Ki67 of > 20%. However this groups together G3 well differentiated neuroendocrine tumours (WD-NET) with poorly differentiated neuroendocrine carcinomas (PD-NEC). Recently, WHO have proposed a new classification for pancreatic NEN, with sub-division into G3 WD-NET and G3 PD-NEC
