#38 Expression of mTOR signaling pathway and effects of mTOR inhibitors on its pathway in human neuroendocrine tumors
Introduction: Neuroendocrine tumors (NET), especially well-differentiated endocrine tumors, are often slow-growing, indolent, and may not become clinically apparent until the manifestations of metastatic spread or carcinoid syndrome. Results of previous studies demonstrated that phosphoinositide 3-kinase (PI3K)/Akt/mTOR signaling pathway may be activated in the great majority of NET cells. mTOR inhibitors are therefore considered effective anti-tumor reagents but they may also induce an activation of PI3K/Akt and MAPK pathways as a compensatory action and reduce their own anti-tumor activities.

#96 Expression of components of the mTOR pathway in gastroenteropancreatic neuroendocrine tumors
Introduction: Recently, the mammalian target of rapamycin (mTOR) inhibitors have entered late phase clinical trials in a broad variety of solid human malignancies, including neuroendocrine tumors (NETs). Since these drugs will certainly be used as routine therapeutics in the near future, it is surprising that information on the exact expression patterns of mTOR and its downstream target 4EBP1 in NETs is still lacking.

#226 Insulin-like Growth Factor-1 Receptor (IGF-1R) and its Inhibition in Non-functioning Neuroendocrine Tumors
Introduction: Insulin-like growth factor-1 receptor (IGF-1R) was reported to be expressed in NET (neuroendocrine tumor) cells but its biological roles and activation status in non-functioning NET are unknown.

#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).

#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.

#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.

#2694 The Incidence of Gastrointestinal Neuroendocrine Tumors in the Russian Population
Introduction: Over the past four decades, the incidence of neuroendocrine tumors (NETs) has increased. The limited choice of treatments, broad clinical variability of the syndrome explains the increased interest in NETs.
