Antiangiogenic therapy has emerged as an important concept in the treatment of solid tumors, including non-small cell lung cancer (NSCLC). Vascular endothelial growth factor (VEGF) represents an important therapeutic target, as it is the primary mediator of angiogenesis and is induced by multiple tumor-relevant stimuli. The anti-VEGF monoclonal antibody bevacizumab has demonstrated a significant clinical benefit in patients with non-squamous cell NSCLC in a randomized phase III trial. ⋯ In some cases, combination therapy with different targeted agents may provide the most comprehensive treatment approach. In a randomized phase II study, bevacizumab in combination with the epidermal growth factor receptor inhibitor erlotinib demonstrated efficacy similar to chemotherapy plus bevacizumab. Ongoing studies are continuing to investigate new agents and identify the patients most likely to benefit from antiangiogenic therapy.
