Preclinical researches indicated a potential synergistic effect of taxanes-containing chemotherapy (TCC) and antiangiogenic agents (AAs) on the treatment of advanced nonsmall-cell lung cancer (NSCLC). The advantage of adding AA to TCC in the real world remains confusing. We summarized the current evidences from relevant phase II/III randomized controlled trials (RCTs) by performing this meta-analyses.Electronic databases were searched for eligible literatures. The primary endpoint was overall survival (OS). Pooled hazard ratios (HRs) and 95% confidence intervals (CIs) for outcomes were calculated using RevMan 5.2.A total of 14 phase II/III RCTs involving 9703 participants were included. Compared to standard TCC, the addition of AA was associated with the significant better OS (HR 0.92, 95% CI 0.87-0.97, P = 0.002), prolonged progression-free survival (HR 0.79, 95% CI 0.71-0.87, P < 0.00001), superior response rate (risk ratio [RR] 1.69, 95% CI 1.47-1.95, P < 0.0001), and disease control rate (RR 1.19, 95% CI 1.08-1.32, P < 0.00001). Subgroup analyses indicated that patient treated with monoclonal antibodies (HR 0.89, 95% CI 0.82-0.96, P = 0.02) as well as application in second-line (HR 0.91, 95% CI 0.85-0.96, P = 0.02) acquired significant OS improvement. Other clinical factors directing significant OS improvement by the combination strategy included nonsquamous cancer (P = 0.002), nonsmokers (P = 0.0005), and female (P = 0.02). Toxicities were greater but generally mild or moderate in the combination group, and were mostly manageable.In summary, the addition of AAs to TCC could improve prognosis of advanced NSCLC. Furthermore, proper selection of patient population and AAs is crucial for clinical trials design and clinical practice in the future.
