BackgroundTalc pleurodesis (TP) and indwelling pleural catheter (IPC) are used for the management of malignant pleural effusion (MPE). Our meta-analysis was conducted to assess the efficacy and safety of both treatments among patients with MPE.MethodsWe acquired pertinent randomized controlled trials (RCTs) by searching PubMed, ScienceDirect, the Cochrane Library, Scopus, Ovid Medline, Embase, Web of Science, and Google Scholar. The endpoints included survival, pleurodesis rates, total drainage, further pleural interventions, hospital days, symptoms, quality of life (QoL), and complications.ResultsWe included four high-quality RCTs. Both treatments were effective among patients with MPE and no previous pleurodesis, with comparable survival and equivalent relief of breathlessness. Additionally, the TP group had higher pleurodesis rates, less total drainage, and fewer all-grade complications (including catheter blockage and cellulitis). However, patients in the TP group had more pleural procedures and relatively longer hospital stays. Additionally, no apparent difference was detected in QoL.ConclusionsTP has better pleurodesis rates, less total drainage, and fewer all-grade complications. However, TP has more pleural procedures and is not feasible for patients with trapped lungs. IPC has fewer further pleural interventions and shorter hospital stays. However, IPC has the nuisance of long-term in situ draining.
