Background and objective: Several clinical trials have reported that intrapleural infusion of bevacizumab with or without cisplatin exhibits encouraging efficacy in nonsquamous non-small cell lung cancer (NS-NSCLC) patients with malignant serous cavity effusion. However, most of the studies included a number of different types of cancers or different hydrops types rather than focusing on one. In addition, no study reported the efficacy and toxicity of intrapleural infusion of bevacizumab and pemetrexed for advanced NS-NSCLC patients with malignant pleural effusion (MPE).
Patients and methods: We retrospectively collected patients with MPE mediated from NS-NSCLC who underwent intrapleural infusion of bevacizumab between August 2012 and February 2017. According to the different combined agents with bevacizumab, we divide patients into two groups: Group 1 (BP Group) intrapleural infusion of bevacizumab combined with pemetrexed and Group 2 (BD group) intrapleural infusion of bevacizumab combined with cisplatin.
Results: A total of 45 patients were enrolled in this study. Twenty-two of them received intrapleuralinfusion of bevacizumab and pemetrexed every 2 weeks, 23 received bevacizumab and cisplatin after draining effusion as much as possible. The progression-free survival for patients in BP group was significantly higher than BD group (P < 0.05) while the overall survival between the two groups was not significantly different (P > 0.05). In addition, there was no statistical difference in adverse effects between two groups.
Conclusion: Intrapleural infusion of bevacizumab and pemetrexed is effective and tolerable for patients with MPE mediated from NSCLC.
