This volume represents a compendium of scientific findings and approaches to the study of angiogenesis in cancer. The second edition of Antiangiogenic Agents in Cancer Therapy is intended to give a current perspective on the state-of-the-art of angiogenensis and therapy directed at this process. Antiangiogenesis is a dynamic and evolving field in oncology. New therapeutic targets continue to emerge followed by the rapid development of new therapeutic agents to be investigated in clinical trials. Optimizing the therapeutic potential of antiangiogenic agents in combination with the other therapies in the armamentarium to fight cancer will be an on-going challenge.
