#3409 Ascl1 and OTP identify four prognostic groups among atypical carcinoids

Introduction: Atypical Carcinoids (AC) according World Health Organization guidelines are well differentiated Lung Neuroendocrine tumor with 2-10 mitoses/2 mm2 and/or with necrosis. Besides morphological differentiation no further tools in predicting AC clinical outcome are proposed.

#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).

#920 High Grade (G3) Neuroendocrine Neoplasms Should Be Further Classified According to Morphological Differentiation

Introduction: Neuroendocrine neoplasms (NENs) with a Ki-67 >20% (Grade 3) are classified together as Neuroendocrine Carcinomas (NEC), and are usually considered as poorly differentiated. However Grade (G)3 NENs may be heterogeneous, with some demonstrating a well-differentiated cell morphology.

#113 Prolonged cell survival in xenografts from human digestive endocrine tumors

Introduction: Gastroenteropancreatic endocrine tumors have the capacity to achieve very large tumor masses despite usually very low proliferative rates. This suggests that neoplastic endocrine cells may have long life spans, implying the development of specific mechanisms able to promote cell survival.
