Advanced-stage non-small-cell lung cancer (NSCLC) is a lethal disease that is treated with combination chemotherapy. Although modest survival benefit has been documented with various platinum-based, two-drug combination chemotherapy regimens, an efficacy plateau has been reached. Bevacizumab, a monoclonal antibody against the vascular endothelial growth factor, is the first molecularly targeted agent that has demonstrated survival advantage when combined with chemotherapy for the treatment of advanced nonsquamous NSCLC. Improvements in all efficacy parameters, including response rate, progression-free survival and overall survival, were noted for advanced nonsquamous NSCLC patients when bevocizumab was added to the combination of carboplatin-paclitaxel compared with the same chemotherapy regimen alone. This has opened the door for expanding the role of bevacizumab in earlier stages of the disease with chemotherapy or radiotherapy. The anti-angiogenesis agents, including the monoclonal antibody and vascular endothelial growth factor tyrosine kinase inhibitors, will be among the most important drugs of the present decade. This article discusses the recent data with bevacizumab in NSCLC and its potential application at various stages of NSCLC.
