We conducted a meta-analysis to evaluate the efficacy of adding any antiangiogenic therapy (AT) to the standard of care in advanced non-small-cell lung cancer (NSCLC). The electronic databases Ovid PubMed, Cochrane Central Register of Controlled Trials, and Embase were searched to identify eligible trials. We included all phase III randomized trials with any line and type of treatment, histology. and AT dose. Pooled hazard ratios (HRs) for overall survival (OS) and progression-free survival (PFS), and pooled odds ratio (OR) for overall response rates (RR) were calculated. We divided the population into 2 subgroups based on the bevacizumab dose. Data of 19,098 patients from 25 phase III trials were analyzed. Compared with the standard of care, the addition of AT did not prolong OS (HR 0.98; 95% confidence interval [CI], 0.96-1.00; P = .1 and HR 0.97; 95% CI, 0.94-1.00; P = .06 for groups 1 and 2, respectively). However, there was a significant improvement in PFS with the addition of AT (HR 0.85; 95% CI, 0.79-0.91; P < .00001 and HR 0.81; 95% CI, 0.75-0.88; P < .00001 for groups 1 and 2, respectively) and overall RR (OR 1.61; 95% CI, 1.30-2.01; P < .0001 and OR 1.72; 95% CI, 1.39-2.14; P < .00001 for groups 1 and 2, respectively). This is the first meta-analysis including only all phase III trials with AT in NSCLC showing no significant effect on OS and an improvement in PFS and RR only. The role of AT in advanced NSCLC is still questionable; strong validated biomarkers are eagerly needed to predict which subgroup might benefit the most from such therapy.
