Abstract
BACKGROUND: Bevacizumab combined with platinum-based chemotherapy has been recommended as the first-line agent in advanced nonsquamous non-small cell lung cancer (NSCLC) without driven gene, but this regimen is not common in the second-line or later-line treatment of non-squamous NSCLC. The aim of this study is to investigate the efficacy and safety of bevacizumab combined with chemotherapy as second-line or later-line treatment in advanced non-squamous NSCLC.Entities:
