Bevacizumab for advanced breast cancer

Abstract

Tumor angiogenesis is an important step in breast cancer development, progression, invasion and metastasis. Pro-angiogenic factors such as VEGF regulate angiogenesis and are targets for drug development. Bevacizumab, an anti-VEGF antibody, has demonstrated significant clinical benefit in several solid tumors, including breast cancer. Its use in combination with either paclitaxel or docetaxel has prolonged progression-free survival and increased response rates in the first-line treatment of patients with metastatic breast cancer. This review article discusses the clinical trials establishing the use of bevacizumab for the treatment of advanced breast cancer.
