ABSTRACT
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.Palavras-chave
