Abstract
Aim: To investigate the efficacy, safety and optimal dosage of bevacizumab in non-squamous, non-small-cell lung cancer (NSCLC) patients with malignant pleural effusion (MPE). Methods: 20 patients were enrolled and received intrapleural injection of bevacizumab (group A: 2.5 mg/kg d1, d8; group B: 5 mg/kg d1, d8; group C: 7.5 mg/kg d1, d8). Results: The objective response rate (ORR) of MPE was 50%. The median progression-free survival (PFS) of MPE was 7.0 months (95% CI 4.9–9.2). The ORR and PFS of MPE from group B were better than those of group A and group C. The most common adverse events (AEs) were hypertension (15%) and anemia (15%). Conclusion: Bevacizumab has certain efficacy in non-squamous NSCLC patients with MPE. Clinical Trial Registration: NCT02942043 (ClinicalTrials.gov).
