angiogenesis is necessary for the growth of neoplasms and the
production of metastasis. The vascular endothelial growth factor (VEGF)
is a homodimeric heparin-binding glycoprotein that binds to
VEGF-receptors and can induce endothelial cell mitosis, invasion, and
eventually capillary tube formation. Bevacizumab, a humanized
monoclonal antibody against VEGF, inhibits tumoral angiogenesis and may
also improve the delivery of chemotherapy to the tumor mass. Some new
antiangiogenic agents, called multi-kinase inhibitors (sorafenib and
sunitinib), have also activity against other receptors, such as
epidermal growth factor-receptor or platelet-derived growth
factor-receptor. A new schedule of treatment (metronomic chemotherapy)
also has antiangiogenic activity.
