#3320 TGF-β increase caspase activation and migration in typical bronchial carcinoids

Introduction: Typical bronchial carcinoids (TBC) are well-differentiated neuroendocrine neoplasms (NEN) whose management can still be very challenging due to reduced sensitivity to therapy. Previous studies have reported TGF-β’s ability to activate mTOR pathway and induce epithelial to mesenchymal transition (EMT). Moreover, preliminary results show an overexpression of TGF-β signalling and caspase activation in TBC.

#2269 Can Insulin-Like Growth Factor 1 (IGF-1), IGF-1 Receptor, Connective Tissue Growth Factor and Ki-67 Labelling Index Have a Prognostic Role in Pulmonary Carcinoids?

Introduction: Altered expression of Insulin-like Growth Factor-1 (IGF-1), its receptor (IGF-1R), Connective Tissue Growth Factor (CTGF) and Hypoxia Factor-1 (HIF-1), has been implicated in tumorigenesis. These factors have not been studied systematically in Pulmonary Carcinoids (PCs).

#1936 The Expression of IGF Signaling Pathway Genes Is Frequently Elevated in Pancreatic Neuroendocrine Tumors, but Is Downregulated in Metastases

Introduction: Studies have implicated EGFR, IGF and mTOR signaling pathways in the regulation of pNET growth. Interpretation of these studies is complex due to tumor subtype heterogeneity and differences in molecular analysis.

#1810 FOXM1 Is Strongly Associated with Cell Proliferation and Is Not Influenced by Metabolic Syndrome in GEP-NETS

Introduction: Gastro-entero-pancreatic neuroendocrine tumors(GEP-NETs) and metabolic syndrome(MS) are both increasing exponentially. MS has been associated with several non NET cancers.

#1725 Safety of Lanreotide 120 mg ATG (LAN) in Combination with Metformin (MET) in Patients (pts) with Progressive Advanced Well-Differentiated (WD) Gastro-Intestinal (GI) or Lung Carcinoids. A Pilot, One-Arm, Open-Label, Prospective Study: The MetNET-2 Trial

Introduction: Anti proliferative effect of LAN ATG 120 mg has been investigated in 204 GI-NET pts in Clarinet study with a 53% reduction in risk of death/progression vs placebo. An increasing number of trials have associated MET with better outcome in cancer pts due to a reduction of insulin/IGF1 levels and modulation of AMPK and TSC1-2/mTOR. The retrospective PRIME-net study conducted on 445 Italian pts, suggest that addition of MET to everolimus and/or SSA provides clinical benefit in diabetic pancreatic NETs.
