Background Malignant pleural effusion (MPE) results in breathlessness and impairment of health-related quality of life (HRQOL). This study reviews the existing literature on HRQOL following invasive interventions in MPE.
Methods Five electronic databases were systematically searched and assessed three times during the review process and last completed on 15 June 2018. We included all studies evaluating HRQOL outcomes for the following interventions: therapeutic thoracocentesis, talc slurry (TS) pleurodesis, indwelling pleural catheter (IPC) insertion and thoracoscopic talc poudrage (TTP) pleurodesis. Meta-analysis was not performed due to substantial heterogeneity in the published data.
Results 17 studies were included in the review reporting HRQOL outcomes in 2515 patients. TTP, TS and IPC were associated with modest but inconsistent improvements in HRQOL up to 12 weeks. No intervention was significantly different from another in HRQOL outcomes at any time point. The attrition to follow-up was 48.3% (664/1374) at 3 months. The overall quality of studies was inadequate.
Conclusion TTP, TS and IPC seem to improve HRQOL in MPE over 4–12 weeks, but there are insufficient longer term data due to high attrition rates. Evidence on the most effective treatment strategy is limited by the small number of randomised or comparative studies.
