Spotlight on bevacizumab in advanced colorectal cancer, breast cancer, and non-small cell lung cancer

BioDrugs. 2006;20(3):193-5. doi: 10.2165/00063030-200620030-00007.


Bevacizumab (Avastin) is a humanized recombinant antibody that prevents vascular endothelial growth factor (VEGF) receptor binding, and inhibits angiogenesis and tumor growth. In patients receiving an irinotecan plus fluorouracil/leucovorin (IFL) regimen for first-line treatment of metastatic colorectal cancer, the addition of bevacizumab significantly increased overall survival by 4.7 months relative to IFL plus placebo. In the second-line treatment of advanced colorectal cancer, patients who received bevacizumab in combination with a fluorouracil/leucovorin plus oxaliplatin (FOLFOX4) regimen had an overall survival time that was 2 months longer than that in patients receiving FOLFOX4. Preliminary results indicated that bevacizumab significantly extended progression-free survival by 4.9 months in patients receiving paclitaxel for the first-line treatment of locally recurrent or metastatic breast cancer. The addition of bevacizumab to paclitaxel plus carboplatin in the first-line treatment of advanced non-small cell lung cancer (NSCLC) significantly prolonged overall survival by >2 months. Bevacizumab has acceptable tolerability in patients with advanced colorectal cancer, breast cancer, or NSCLC, with the majority of adverse events being generally mild and clinically manageable. Thus, bevacizumab provides a highly effective addition to standard chemotherapeutic regimens for advanced colorectal cancer, breast cancer, and NSCLC.
