#3014 The Number of Positive Nodes Accurately Predicts Recurrence after Distal Pancreatectomy for Nonfunctioning Neuroendocrine Neoplasms
Introduction: The most appropriate staging system of metastatic lymph nodes (N) for resected pancreatic neuroendocrine tumors (PanNETs) remains unclear, especially regarding those resected by distal pancreatectomy (DP).

#19 Antitumor activity of Pasireotide (SOM230) alone and in combination with Everolimus (RAD001) in DU-145 human prostate cancer model
Introduction: Pasireotide (SOM230) is a novel multi-receptor ligand somatostatin analogue with high affinity for somatostatin receptor subtypes sst1,2,3 and sst5. Like octreotide, which binds primarily to sst2, it inhibits hypersecretion of hormones from patients with functional pituitary tumors and gastroenteropancreatic neuroendocrine (GEP/NET) tumors. In addition, tumor shrinkage has been observed with both compounds in patients with acromegaly, Cushing’s disease and GEP/NETs, but its tumor-reducing mechanism of action has so far not been revealed. In patients with breast and liver cancer, octreotide had little or no antitumor activity.

#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.

#41 Immunohisochemical evaluation of EMT regulators, E- and N-cadherin in neuroendocrine Tumors of the Gastro-Entero-Pancreativ system
Introduction: Local tumor invasion represents the first step of the metastatic cascade of carcinomas, and requires changes in cell adhesion and migration properties of tumor cells. This biologic process is known as epithelial-mesenchymal transition (EMT). One key biochemical change associated with EMT is the loss of E-cadherin expression promoted by specific transcriptional repressors such as Snail, Slug, and Twist. Overexpression of EMT inducers increases other factors, such as FoxC2, although its role in EMT is poorly understood. Neuroendocrine tumors (NETs) of the gastroenteropancreatic (GEP) system, originated from the diffuse endocrine system, represent a heterogeneous group of tumors. Their prevalence has increased substantially over the past three decades, without substantial improvements in their clinical management, and their variable clinical course cannot be predicted by common clinicopathological parameters. Thus, new prognostic markers are urgently needed.

#48 Preliminary report of the use of everolimus in a patient with progressive medullary thyroid carcinoma
Introduction: Medullary thyroid carcinoma (MTC) accounts for about 5-10% of all thyroid cancers, and while disease localized to the thyroid can be cured by surgery, there is no effective treatment for disseminated MTC. Constitutive activation of the RET proto-oncogene is implicated in familial and a proportion of sporadic cases, and up-regulates the AKT/PI3-kinase/mTOR signal transduction pathway. Recent studies have shown that the inhibitor of mTOR, everolimus (RAD001, Novartis, Basel), can inhibit the proliferation of the TT cell line and human MTC tumor cells in vitro. Clinically, everolimus has been shown to attenuate the progression of some gastrointestinal neuroendocrine tumors, but its clinical use in MTC has not yet been evaluated.

#66 Adrenocortical cancer: a therapeutic approach with everolimus (RAD001)
Introduction: Adrenocortical cancer (ACC) is a rare disease with very poor outcome. ACC responds poorly to standard chemotherapy. Mitotane, used as adjuvant therapy to surgery, prolongs recurrence-free survival, but the response is limited to 23% of patients and resistance occurs in the majority of patients (1). There is no curative therapy for ACC. Pre-clinical studies have shown involvement of both IGF-2/IGF-1R and Akt/mTOR pathways in ACC, and IGF-1R and mTOR inhibitors inhibited cell proliferation of human adrenocortical carcinoma cell lines in vitro (2,3,4).
