P2.01-030 - Real World Study of Bevacizumab-Contained Regimen as First Line Therapy in Chinese Patients with Advanced NSCLC (ID 9019)

- Abstract
Background:
Bevacizumab has been demonstrated significant survival benefits in addition to chemotherapy in patients with advanced NSCLC from several large scale randomized control trials. We aimed to explore the clinical impact of first-line bevacizumab-contained regimen (B+) versus non-bevacizumab regimen (non-B) for patients with advanced non-squamous non-small cell lung cancer (NS-NSCLC) in the real world setting.
Method:
From July 2009 to December 2016, patients with advanced NS-NSCLC who received first-line therapy with or without bevacizumab were retrospectively collected from Cancer Hospital Chinese Academy of Medical Sciences. Primary outcome was progression-free survival (PFS), and the secondary objectives were objective response rate (ORR), disease control rate (DCR) and safety. Meanwhile exploratory analysis was conducted in each sub-groups regarding to EGFR and ALK status.
Result:
149 patients met selection criteria, 62 in B+ group and 87 in non-B group. Chemotherapy was the based treatment in each group, 57/62 and 71/87 respectively. Median follow-up time was 10.7 months. The baseline characteristics were well balanced. In overall population, median PFS were significantly longer in B+ than in the non-B group: 9.7 vs 7.0 months, HR 0.52, 95% CI 0.30-0.91, P=0.0184. Both ORR and DCR had improved trends in B+ group. In wild type patients, median PFS of B+ group was 11.3 months compared with 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 population, median PFS was 11.3 months (B+ group) comparing to 6.0 months (non-B group) (HR, 0.53; 95% CI, 0.28-1.02; P=0.0520). The ORR and DCR had consistently similar response in subgroups comparison (Table 1). Safety profile was acceptable in both groups and no new unexpected findings were found. Figure 1
Conclusion:
Our real world analysis further confirmed that bevacizumab-contained therapy as first line treatment was indeed superior in clinical benefits than non-bevacizumab regimen in Chinese patients with advanced NS-NSCLC in a real world.
