title: Tumoral angiogenesis: review of the literature.
abstract: Tumoral 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.
