- Abstract
Background: Real-world evidence is lacking on the impact of bevacizumab added to carboplatin/paclitaxel (Bev + CP) therapy versus CP alone for patients with non-squamous non-small cell lung cancer (NS-NSCLC), particularly in those excluded from clinical trials. Methods: This is a retrospective electronic medical record analysis of patients who received first-line therapy with Bev + CP or CP between 1 October 2006 and 30 June 2013. We identified four subsets: elderly patients (≥65 years), patients with brain/central nervous system (CNS) metastases, patients with Eastern Cooperative Oncology Group performance status (ECOG PS) ≥2, and patients receiving anticoagulation. We used descriptive statistics to describe patient characteristics and treatment patterns and evaluated progression-free survival (PFS) and overall survival (OS) using survival analyses. Results: The study included 431 patients (Bev + CP: 231; CP: 200). The Bev + CP cohort was more likely to receive four or more cycles of induction therapy (72 vs. 50 %) and was more likely to receive maintenance therapy (45 vs. 21 %) than patients receiving CP. In the overall population, median PFS and OS were significantly longer in the Bev + CP cohort than in the CP cohort: 6.7 vs. 5.1 months (hazard ratio [HR] 0.74; 95 % confidence interval [CI] 0.59-0.92; p = 0.008) and 11.9 vs. 9.0 months (HR 0.57; 95 % CI 0.44-0.73; p < 0.001), respectively. Treatment with Bev + CP in patients aged ≥65 years and in those with brain/CNS metastases was also associated with a significant risk reduction in PFS (35 and 51 %, respectively; p < 0.05 for both) and OS (46 and 62 %, respectively; p < 0.05 for both) compared with CP alone. Conclusion: Bev + CP is associated with a significant improvement in PFS and OS in patients with NS-NSCLC and in subsets with brain/CNS metastases and those aged ≥65 years.
