Management of solitary fibrous tumours of the pleura:a systematic review and meta-analysis
Background:Solitary fibrous tumours of the pleura (SFTP), or pleural fibromas, are rare tumours that generally, but not universally, follow a benign course. Surgical resection is the standard treatment, but there are no evidence-based guidelines regarding the management of these tumours. Methods:Five databases were searched from inception to April 1, 2019 for studies reporting on SFTP management. Results:Twenty-seven studies met the inclusion criteria (1542 patients, all non-comparative case series); 98% of these patients underwent resection and all SFTP included were pathologically diagnosed. 394 out of 1299 cases (30.5%, 95% CI 27.8-32.8%) were malignant with recurrence rates of between 0% and 42.9%. A pleural effusion was always associated with a negative outcome, but no other features were consistently reported to have negative associations. Preoperative biopsies incorrectly reported malignant histology in two studies. Over 25% of cases of recurrence occurred when a complete (R0) resection had been achieved. The first recurrence occurred >5 years after the initial resection in at least 23% of cases. Conclusions:There is strong evidence to support long-term surveillance after surgical resection of SFTP, even where a complete (R0) resection has been achieved; however, there is no clear evidence to inform clinicians regarding the selection of patients who should undergo resection. The rates of malignant SFTP and SFTP recurrence are higher than previously reported. Only those that were pathologically diagnosed or resected were included, which may bias the data towards more aggressive tumours. Data collection on radiologically diagnosed SFTP is required to draw conclusions regarding the timing and need for intervention
Critical analysis of the utility of initial pleural aspiration in the diagnosis and management of suspected malignant pleural effusion
INTRODUCTION:Current guidelines recommend an initial pleural aspiration in the investigation and management of suspected malignant pleural effusions (MPEs) with the aim of establishing a diagnosis, identifying non-expansile lung (NEL) and, at times, providing a therapeutic procedure. A wealth of research has been published since the guidelines suggesting that results and outcomes from an aspiration may not always provide sufficient information to guide management. It is important to establish the validity of these findings in a 'real world' population. METHODS:A retrospective analysis was conducted of all patients who underwent pleural fluid (PF) sampling, in a single centre, over 3 years to determine the utility of the initial aspiration. RESULTS:A diagnosis of MPE was confirmed in 230/998 (23%) cases, a further 95/998 (9.5%) were presumed to represent MPE. Transudative biochemistry was found in 3% of cases of confirmed MPE. Positive PF cytology was only sufficient to guide management in 45/140 (32%) cases. Evidence of pleural thickening on CT was associated with both negative cytology (χ2 1df=26.27, p<0.001) and insufficient samples (χ2 1df=10.39, p=0.001). In NEL 44.4% of patients did not require further procedures after pleurodesis compared with 72.7% of those with expansile lung (χ2 1df=5.49, p=0.019). In patients who required a combined diagnostic and therapeutic aspiration 106/113 (93.8%) required further pleural procedures. CONCLUSIONS:An initial pleural aspiration does not achieve either definitive diagnosis or therapy in the majority of patients. A new pathway prioritising symptom management while reducing procedures should be considered
European Respiratory Society Statement on Thoracic Ultrasound
Thoracic ultrasound is increasingly considered to be an essential tool for the pulmonologist. It is used in diverse clinical scenarios, including as an adjunct to clinical decision making for diagnosis, a real-time guide to procedures, and a predictor or measurement of treatment response. The aim of this European Respiratory Society task force was to produce a statement on thoracic ultrasound for pulmonologists using thoracic ultrasound within the field of respiratory medicine. The multidisciplinary panel performed a review of the literature, addressing major areas of thoracic ultrasound practice and application. The selected major areas include equipment and technique, assessment of the chest wall, parietal pleura, pleural effusion, pneumothorax, interstitial syndrome, lung consolidation, diaphragm assessment, intervention guidance, training, and the patient perspective. Despite the growing evidence supporting the use of thoracic ultrasound, the published literature still contains a paucity of data in some important fields. Key research questions for each of the major areas were identified, which serve to facilitate future multi-centre collaborations and research to further consolidate an evidence-based use of thoracic ultrasound, for the benefit of the many patients being exposed to clinicians using thoracic ultrasound

Diagnostic yield and safety of image-guided pleural biopsy: a systematic review and meta-analysis
Background: The diagnostic yield (DY) and safety of computed tomography(CT)-guided and thoracic ultrasound(TUS)-guided biopsy of pleural lesions have been investigated in a number of studies, but no synthesis of data has been performed
Aims and Objectives: We aim to provide the first systematic review and meta-analysis on CT- versus TUS-guided biopsy in the diagnosis of pleural lesions.
Methods: We searched Medline and Embase for all studies reporting outcomes of interest published up to April 2018. Summary estimates were derived using the random-effects model. Cumulative meta-analysis assessed the influence of increasing adoption of the procedures over time
Results: Thirty original studies were included. The pooled DYs of the two procedures were high and differed less than 10%, being 84% for TUS-guided biopsy and 93% for CT-guided biopsy. Safety was good for both the techniques, with an adverse event rate of 7% and 3% for CT- and TUS-guided biopsy, respectively. DY of the ultrasound technique significantly improved over time, while no time-effect was observed for CT-guided biopsy
Conclusions: CT- and TUS-guided pleural biopsy are both sensitive techniques without meaningful differences in DYs and safety. Considering that TUS is non-ionising and easily performed at the bedside, this data suggest that TUS should be the preferred approach in presence of adequate skills, which challenges the current guideline
Efficacy of Small versus Large-Bore Chest Drain in Pleural Infection: A Systematic Review and Meta-Analysis
Background: Pleural infection represents a significant clinical challenge worldwide. Although prompt drainage of pleural fluid is thought to play a key role in pleural infection management, the optimal size of intrapleural catheter has yet to be defined. Objectives: The aim of this systematic review and meta-analysis was to summarize data on efficacy and complications of small-bore drain (SBD), defined as ≤14F, in comparison to large-bore drain (LBD) in patients with pleural infection. Method: We searched MEDLINE and Embase for all studies reporting outcomes of interest published up to October 2021. Two authors reviewed selected full text to identify studies according to predefined eligibility criteria. Summary estimates were derived using the random-effects model. Results: Twelve original studies were included for qualitative analysis and 7 of these for quantitative analysis. The surgical referral rate of SBD and LBD were, respectively, 0.16 (95% confidence interval [CI], 0.12-0.21) and 0.20 (95% CI, 0.10-0.32), the pooled mortality were 0.12 (95% CI, 0.05-0.21) and 0.20 (95% CI, 0.10-0.32), and the length of hospital stay was 24 days in both groups. Data on complications suggest similar proportions of tube dislodgement. Intensity of pain was evaluated in one study only, reporting higher scores for LBD. Conclusions: This systematic review and meta-analysis provide the first synthesis of data on performance of SBD and LBD in management of pleural infection, and, overall, clinical outcomes and complications did not substantially differ, although the limited number of studies and the absence of dedicated randomized trials does limit the reliability of results
