RESUMEN
BACKGROUND: Malignant pleural effusion is one of the most important complications of metastatic cancer, and recurrent pleural effusions do not only have an impact on survival but also cause a huge repercussion on a patient's quality of life. OBJECTIVES: The main objective was to describe quality of life status before and after pleurodesis in patients with malignant pleural effusion. Secondary, we aimed to find predictors of quality of life improvement in such a population. METHODS: Retrospective analysis of a database collected prospectively. We included patients who underwent pleurodesis from June 2004 to July 2014. Quality of life was evaluated through the WHOQOL-BREF questionnaire and applied before and 30 days after pleurodesis. We used a paired t test and the Wilcoxon rank-sum to compare pre-/post-pleurodesis results, Kaplan-Meier curves for survival analysis, and multiple linear regressions to find predictors of quality of life improvement. RESULTS: 183 patients were included (145 were women). Mean age was 58.3 ± 12.3 years, the most numerous primary tumor was breast cancer. Median survival time was 9 months. Dyspnea was the most prevalent symptom. Baseline results showed that patients had low quality of life scores. After pleurodesis, there was a significant improvement in respiratory symptoms, physical domain, and general health. Linear regression showed an improvement in physical domain with the sclerosing agent nitrate (p = 0.005). Male gender (p = 0.002) and a higher lymphocyte count (p = 0.01) were inversely associated with improvement in physical domain. CONCLUSIONS: Pleurodesis improved symptoms and quality of life in patients with malignant pleural effusion. Gender, lymphocyte count, and sclerosing agent might interfere with quality of life improvement.

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. TRIAL REGISTRATION NUMBER: CRD42016051003.
