The Role of Bevacizumab in the Treatment of Non‐Small Cell Lung Cancer: Current Indications and Future Developments

Learning Objectives After completing this course, the reader will be able to: Describe the main clinical trials of bevacizumab combined with chemotherapy in the treatment of advanced NSCLC. Describe the main clinical trials of bevacizumab combined with other targeted therapies in the treatment of advanced NSCLC. Describe some ongoing trials of bevacizumab in the treatment of NSCLC and try to define future developments of bevacizumab in this clinical setting.

Advances in the knowledge of tumor biology and mechanisms of oncogenesis have granted the singling out of several molecular targets for NSCLC treatment. Bevacizumab, an anti–growth factor vascular endothelial growth factor (VEGF) monoclonal antibody, is the antiangiogenic agent at the most advanced stage of development in the treatment of solid tumors and also in NSCLC treatment. Bevacizumab, combined with platinum‐based chemotherapy, has been demonstrated to improve efficacy outcomes over chemotherapy alone in the treatment of nonsquamous advanced NSCLC in two phase III randomized trials. These represent the first evidence of improvement in treatment outcomes of chemotherapy with targeted therapies in the first‐line treatment of advanced NSCLC. Future clinical developments of bevacizumab in NSCLC treatment will include the combination of this agent with other targeted therapies in advanced disease (especially with erlotinib, an epidermal growth factor receptor tyrosine kinase inhibitor) and the integration of this agent into combined modality approaches for the treatment of early‐stage and locally advanced disease.
