Bevacizumab in combination with anticancer drugs for previously treated advanced non-small cell lung cancer.

ABSTRACT

Non-small cell lung cancer (NSCLC) accounts for about 85% of all lung cancer cases. Patients with NSCLC often have an advanced disease at the time of diagnosis, with a 1-year survival rate about 10-15% under the best support treatment. As therapeutic methods for lung cancer developed rapidly in recent years, the prognosis of stage IIIB or IV NSCLC also improve to a large extend. Bevacizumab is a monoclonal antibody against VEGFR which inhibits abnormal vascular growth in malignant tumors. In October 2006, bevacizumab was approved by the U.S. Food and Drug Administration (FDA) for first-line use in advanced NSCLC. For patients with advanced NSCLC who failed in previously platinum-based chemotherapy, bevacizumab also showed enhancing efficacy to antitumor drugs recommended by the latest NCCN guideline. This review intends to present the recent progress and prospects of bevacizumab in second- or third-line treatment for patients with refractory NSCLC.
