Abstract:

Objective To systematically evaluate the clinical efficacy and safety of external application of traditional Chinese medicine in the treatment of malignant pleural effusion (MPE), and to provide evidence-based support for clinical application. Methods The databases including CNKI, VIP, Wanfang Data, Chinese Biology Medicine, PubMed, Embase, Cochrane Library, and Web of Science were searched to retrieve the studies of randomized controlled trials (RCTs) on external application of traditional Chinese medicine for MPE published from inception to March 18, 2026. The patients were divided into experimental group (receiving external application of traditional Chinese medicine alone or as an adjunct to conventional Western medical treatment) and control group (receiving conventional Western medical treatment alone or placebo external application). RevMan 5.4 and R 4.3.3 softwares were used to conduct the meta-analysis. The outcome measures included pleural effusion response rate, Karnofsky performance status (KPS) score, KPS score improvement rate, and incidence of adverse reactions. This systematic review was prospectively registered in PROSPERO (registration number: CRD420251178277). Results A total of 25 RCTs involving 1 616 patients were included. The meta-analysis results showed that compared with control group, the pleural effusion response rate of the patients in experimental group was significantly increased [risk ratio (RR)=1.30, 95% confidence interval (CI): 1.22-1.40, P<0.000 1], the KPS score was significantly increased [mean difference (MD)=9.28, 95%CI: 6.79-12.76, P<0.000 1], and the KPS score improvement rate was significantly increased (RR=1.42, 95%CI: 1.15-1.74, P=0.000 9). For safety outcomes, compared with control group, the incidences of gastrointestinal reactions (RR=0.65, 95%CI: 0.51-0.82, P=0.000 3), leukopenia (RR=0.56, 95%CI: 0.33-0.93, P=0.03), and chest pain (RR=0.80, 95%CI: 0.67-0.97, P=0.02) of the patients in experimental group were significantly decreased, while the incidence of local skin reactions was significantly increased (RR=8.38, 95%CI: 2.58-27.15, P=0.000 4). Conclusion External application of traditional Chinese medicine, as an adjunctive treatment, shows potential value in improving the pleural effusion response rate and functional status in the patients with MPE, but skin adverse reactions should be closely monitored.
