#2742 Anti-Tumor Effects of Semaphorin 4D Blockade Unravel a Novel Pro-Invasive Mechanism of Vascular Targeting Agents

Introduction: One of the main consequences of inhibition of neovessel growth produced by angiogenesis inhibitors is increased intratumor hypoxia. Growing evidence indicates that tumor cells escape from this hypoxic environment to better nourished locations, presenting hypoxia as a positive stimulus for invasion. Particularly, anti-VEGF/R therapies produce hypoxia-induced invasion and metastasis in a spontaneous mouse model of pancreatic neuroendocrine cancer, RIP1-Tag2.

#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).

#1850 Influence of VEGF Splicing on Microvessel Density and Architecture in Pancreatic Neuroendocrine Tumours

Introduction: Hypoxia in human tumours is associated with a poor prognosis and is characterized by the stabilization of HIF1α, upregulation of VEGF, and a high microvessel density (MVD). Interestingly, although pancreatic neuroendocrine tumours (pNETS) showing hypoxia signalling also have a poor prognosis, they paradoxically display a low MVD. We hypothesized that this paradoxon might be explained by alternative splicing of VEGF.

#1772 Expression of Truncated Functional Subtype 5 Somatostatin Receptor Variant (sst5TMD4) in GEP-NETs and Association with Relevant Pathways Involved in NET Tumorigenesis

Introduction: Sst5TMD4, which is derived from a non-canonical splicing process of sst5 receptor, is overexpressed in several endocrine tumors and associated with a worse prognosis.
