#437 mTOR Expression in Primary Pancreatic Neuroendocrine Tumors and their Metastases
Introduction: The mammalian target of rapamycin (mTOR), an important regulator of cell proliferation and invasion, is activated in pancreatic neuroendocrine tumors (PNETs). Information on detailed expression of mTOR in locally advanced or metastatic PNET is poorly described.

#1221 Pancreatic Location, High Proliferation and Low p-mTOR Expression Levels Are More Frequent in Neuroendocrine Tumor Patients Responsive to mTOR Inhibitors: Results from a Preliminary Study
Introduction: MTOR inhibitors are approved for the treatment of advanced neuroendocrine tumors. However, scarce data are available on clinical or pathological predictors of response to these agents

#592 Expression of PTEN and mTOR in Pancreatic Neuroendocrine Tumors and Their Clinical Significance
Introduction: mTOR is currently under investigation as a potential target for anticancer therapy. Loss of PTEN, the negative regulators of the PI3K-Akt-mTOR pathway, have been associated with cancer.

#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.

#513 Correlation Between mTOR Pathway and Clinical Outcomes in Patients with Well-Differentiated Neuroendocrine Tumors Treated with Everolimus
Introduction: Everolimus has been studied in preclinical and clinical settings, showing it to be active and effective. Tumors exhibiting the constitutively activated phosphatidylinositol-3-kinase-AKT-mTOR (PI3K/AKT/mTOR) pathway, are potentially susceptible to mTOR inhibitors. Even though Everolimus is both an antiproliferative and anti-angiogenic drug, we do not know the possible prognostic or predictive role of p-mTOR pathway.

#1775 Potential Therapeutic Targets for Gastric Poorly Differentiated Neuroendocrine Carcinoma
Introduction: Gastric poorly differentiated neuroendocrine carcinoma (G-PDNEC) is rare and aggressive. Patients often present with distant metastases at initial diagnosis.

#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.

#276 Mammalian Target of Rapamycin Pathway Activation is Associated with RET Mutation Status in Medullary Thyroid Carcinoma
Introduction: The genetic pathways involved in medullary thyroid carcinoma (MTC), except for RET mutations, are largely unknown, as well as the detailed expression mapping of intracellular signalling transducers.

#701 High Expression of Mammalian Target of Rapamycin (mTOR) in NF1-Related Periampullary Neuroendocrine Tumors
Introduction: Neurofibromatosis type 1 (NF1) is a rare inherited disorder associated with cutaneous lesions and neoplasms in the nervous and gastroenteropancreatic systems, including periampullary NETs. NF1-coded protein, neurofibromin, is a tumor suppressor that negatively regulates the mammalian target of rapamycin (mTOR). Preclinical in vitro and in vivo studies demonstrated a constitutive activation of mTOR pathway associated with significant antineoplastic effects of mTOR inhibitors in NF1-related glial tumor models.
