Vascular endothelial growth factor concentrations from platelets correlate with tumor angiogenesis and grading in a spontaneous canine non-Hodgkin lymphoma model

Abstract

Published data strongly suggest that tumor progression and malignancy are associated with increased angiogenesis. However, no data have been published concerning the relationship between microvascular density (MVD), tumor cytosol, and blood vascular endothelial growth factor (VEGF) concentrations in canine non-Hodgkin lymphoma (C-NHL), a neoplasm that shares biological and clinical characteristics with human NHL. We have evaluated MVD and tumor cytosol, serum (S), platelet-poor plasma (P-PP), plasma-activated platelet rich (P-APR) VEGF concentration in a series of 63 B-cells C-NHL by means of immunohistochemistry and enzyme-linked immuno-sorbent assay (ELISA) detection of VEGF. We found that MVD, VEGF from cytosol, and VEGF from P-APR are significantly correlated (p ranging from 0.001 to 0.003) and that these parameters paralleled with the malignancy degree of NHL. Accordingly, spontaneous C-NHL seems to be an interesting model to study the role of angiogenesis as interspecies pathway of tumor malignancy and we suggest that VEGF from P-APR might be a novel useful circulating bio-marker of tumor angiogenesis.
