Background  Large scale randomized controlled trials have demonstrated that the use of bevacizumab in addition to chemotherapy in patients with advanced non‐small cell lung cancer (NSCLC) conveys significant survival benefits. We explored the clinical impact of a first‐line regimen containing bevacizumab (B+) versus a non‐bevacizumab regimen (non‐B) in advanced non‐squamous NSCLC (NS‐NSCLC) patients in a real world setting.    Methods  The medical records of patients with advanced NS‐NSCLC who received first‐line therapy with or without bevacizumab were retrospectively collected. The primary outcome was progression‐free survival (PFS), with secondary objectives of objective response rate (ORR), disease control rate (DCR), and safety. Exploratory analysis of  EGFR  and  ALK  status was conducted in subgroup.    Results  One hundred and forty‐nine patients met the selection criteria: 62 in the B+ and 87 in the non‐B group. The baseline characteristics were well balanced. In the overall population, the median PFS was significantly longer in the B+ than in the non‐B group (9.7 vs. 7.0 months, hazard ratio [HR] 0.52, 95% confidence interval [CI] 0.30–0.91;  P  = 0.0184). Improved trends in both ORR and DCR were observed in the B+ group. In wild‐type patients, the median PFS of the B+ was 11.3 compared to 5.5 months in the non‐B group (HR 0.43, 95% CI 0.20–0.91;  P  = 0.0234). In wild type and unknown populations, the median PFS was 11.3 (B+) compared to 6.0 months (non‐B) (HR 0.53; 95% CI 0.28–1.02;  P  = 0.0520). The safety profile was acceptable in both groups and no unexpected findings were observed.    Conclusion  Our analysis confirmed that a first‐line regimen containing bevacizumab showed superior clinical benefits over a non‐bevacizumab regimen in Chinese patients with advanced NS‐NSCLC in a real world setting.
