We conducted the phase II trial of chemotherapy with bevacizumab in patients with MPE.
MPE was well controlled without pleurodesis in patients treated with bevacizumab.
Chemotherapy with bevacizumab demonstrated significant efficacy in patients with MPE.
The level of VEGF in plasma and MPE might be predictive for bevacizumab-based treatment benefit.
MPE: malignant pleural effusion; VEGF: vascular endothelial growth factor.
