In the past decade, many angiogenesis inhibitors have been developed for clinical use in oncology. Surgeons, radiotherapists as well as medical oncologists have been investigating with much effort and enthusiasm the translation of these agents from the preclinical setting into treatment strategies of patients. Recently, for the first time in history, the angiogenesis inhibitor bevacizumab (avastin), a humanized anti-vascular endothelial growth factor (VEGF) antibody, showed a survival benefit of 4.7 months in a phase III clinical trial in patients with advanced colorectal cancer when this agent was given in combination with chemotherapy. At the annual meeting of the American Association of Clinical Oncology 2005, similar results of bevacizumab in lung, breast and ovarian cancer clinical trials have been shown. These landmark studies proofed for the first time in the clinical setting that Dr. Folkman back in 1971 was right by proposing: "in order to stop tumor growth, one should attack its blood supply". Nowadays it seems trivial to propose such a hypothesis, at that time it was a very provocative hypothesis and it took more than 30 years to proof this hypothesis in the clinic. Although one may be excited about this major finding, there is no time to relax. The survival benefit of bevacizumab is only about 4 months. Therefore more potent antiangiogenic agents and more active treatment strategies are urgently warranted. Newer angiogenesis inhibitors that are currently in preclinical or early clinical development have shown in preclinical experiments improved antitumor activities. In addition, combinations of biological agents that interfere in multiple biological pathways in cancer growth including chemotherapy, are of major clinical interest as well. The multimodality approach in which surgeons, radiotherapists and medical oncologists collaborate needs to be explored as well. In a variety of cancer types, like breast colon and lung cancer, these specialists should design multimodality strategies based on current standard treatment in which they incorporate angiogenesis inhibitors in the right time frame of surgery and radiotherapy. In this review we will bring you up to date on the clinical development of angiogenesis inhibitors and we will summarize the multimodality strategies that are under development.
