Overview of anti-VEGF therapy and angiogenesis. Part 1: Angiogenesis inhibition in solid tumor malignancies.
Several new agents that target the vascular endothelial growth factor (VEGF) pathway and inhibit angiogenesis are emerging as promising therapies in multiple cancer types. Bevacizumab, a humanized monoclonal antibody to VEGF-A, is currently approved in combination with intravenous 5-fluorouracil-containing regimens for the first-line treatment of metastatic colorectal cancer and recently demonstrated clinically important results in combination with chemotherapy in patients with non-small cell lung cancer and metastatic breast cancer. Other anti-VEGF agents that have shown benefit in various cancer types will be discussed in this monograph. Despite the often striking results observed with anti-VEGF agents, several unanswered questions remain, such as the optimal duration of therapy and patient selection criteria. These other issues, including the biologic rationale for anti-VEGF therapy, as well as recent clinical trial data with anti-VEGF agents in colorectal, pancreatic, lung, kidney, and brease cancers, are discussed.
