#1668 Classification of Lung Neuroendocrine Neoplasms (Lung-NENs) According to WHO 2010 for Gastroenteropancreatic NENs (GEP-NENs) Has Prognostic Relevance and Includes Lung-NETs G3

Introduction: The classification of lung neuroendocrine neoplasms (Lung-NENs) according to the WHO classification 2010 for GEP-NENs, including a provisional category for Lung-NET G3 with Ki67 >20%, may have prognostic implications.

#1666 Prognosis and Incidence in Pancreatic and Gastrointestinal Neuroendocrine Neoplasms with Emphasis on “NET G3”: An Analysis of 198 Cases from Japan

Introduction: Prognostic impact of well differentiated pancreatic neuroendocrine neoplasms (PanNENs) with a Ki67 >20%, provisionally called NET G3, needs to be validated and compared to poorly differentiated neuroendocrine carcinomas (NECs). Moreover, the frequency of NET G3 among gastrointestinal NENs (GI-NENs) has so far not been studied.

#1286 A Comparative Analysis of Ki67 Index of the High Grade Neuroendocrine Neoplasms Arising in the Gastrointestinal Tract and the Pancreas

Introduction: A common classification has been used for NET in gastrointestinal tract (GI-NET) and pancreas (P-NET), but heterogeneity has been reported in high grade tumors; well-differentiated G3 (WDG3), poorly differentiated NEC (NEC), and mixed adenoneuroendocrine carcinoma (MANEC).
