BackgroundAlthough there are new treatments for non-small cell lung cancer with malignant pleural effusion, these therapies are prone to recurrent pleural effusion and poor in efficacy. And recombinant human endostatin is a new type of anti-tumor angiogenesis drug independently developed in my country. It has the effect of inhibiting tumor angiogenesis, inhibiting tumor proliferation and differentiation, and effectively inhibiting the formation and recurrence of malignant pleural effusion. Therefore, this study is aim to systematically review the efficacy and safety of intrapleural injection of endostar combined with cisplatin in the treatment of non-small cell lung cancer (NSCLC) with malignant pleural effusion.MethodsDatabases including Cochrane Library, PubMed, CBM, Embase, CNKI, and WanFang Data were searched to collect randomized controlled trials about endostar combined with cisplatin for NSCLC with malignant pleural effusion from inception to April 2022. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias in included studies. Finally, the meta-analysis was made by using RevMan 5.4.1 software.ResultsA total of 11 randomized controlled trials involving 814 patients were finally included. The results of the meta-analysis showed that: The overall response rate and the improvement rate of quality of life in the endostar combined with cisplatin group were higher than that of the cisplatin alone group (relative risk = 1.58, 95% confidence interval = 1.42-1.76, P < .00001; relative risk = 1.63, 95% confidence interval = 1.38-1.93, P < .00001, respectively). Meanwhile, there were no significant differences between the 2 groups in the incidence of gastrointestinal reaction, the incidence of leucopenia, the incidence of thrombocytopenia, and the incidence of hypodynamia (all P values > .05).ConclusionCompared with cisplatin, intrapleural injection of endostar combined with cisplatin could improve the overall response rate and the quality of life of NSCLC patients with malignant pleural effusion. Due to the limited quality and quantity of included studies, more high-quality studies are needed to verify the above conclusion.Copyright © 2022 the Author(s).
