Meta-Analysis
OBJECTIVES
Recent studies have suggested the usefulness of preoperative bronchoscopic marking techniques for the localization of pulmonary nodules in thoracic surgery. This systematic review and meta-analysis aimed to evaluate the efficacy and safety of preoperative bronchoscopic marking.
METHODS
The PubMed and Cochrane Library databases were searched for clinical studies evaluating preoperative bronchoscopic marking for pulmonary resection. Non-comparative and random effects model-based meta-analyses were conducted to calculate the pooled success and complication rates of bronchoscopic marking.
RESULTS
Twenty-five eligible studies were included. Among these, 15 studies conducted dye marking under electromagnetic navigation bronchoscopy, 4 used virtual-assisted lung mapping and 7 used other marking methods. The overall pooled successful marking rate, successful resection rate and complete resection rate were 0.97 [95% confidence interval (CI) 0.95-0.99], 0.98 (95% CI 0.96-1.00) and 1.00 (95% CI 1.00-1.00), respectively. The overall pooled rates of pleural injury and pulmonary haemorrhage were 0.02 (95% CI 0.01-0.05) and 0.00 (95% CI 0.00-0.00), respectively.
CONCLUSIONS
This meta-analysis demonstrated that bronchoscopic marking is very safe and effective. Bronchoscopic marking should be considered, especially if there are concerns about the safety of other localization methods.

Meta-Analysis
OBJECTIVES
to perform a meta-analysis of cohort studies on lung cancer mortality in occupational sectors exposed to asbestos, particularly in the construction sector, and to use data from Italian cohorts exposed to asbestos to estimate the number of lung cancer cases attributable to asbestos in Italy.
METHODS
systematic literature review and estimation of lung cancer deaths and cases attributable to asbestos in Italian cohorts and from the Italian National Register of Malignant Mesothelioma (ReNaM).
SETTING AND PARTICIPANTS
the literature search was conducted in Medline and Embase (Ovid), including papers published from 1999 to May 2019. The following sectors were considered most exposed to asbestos: asbestos-cement, rolling-stock, shipyards, dockyards, glass workers, insulators, asphalt roll production workers, industrial ovens, miners. Moreover, the construction sector was included.
MAIN OUTCOME MEASURES
the standardized mortality ratio (SMR) was estimated from the meta-analysis of the literature review. The ratio lung cancer to mesothelioma attributable cases was estimated by occupational sector from the Italian cohorts. For the construction sector, the ratio lung cancer to mesothelioma cases was estimated within the exposed workers estimated by CAREX (1990-1993). The ratios were applied to the mesothelioma cases registered at the ReNaM for the 2010-2015 period, to obtain a national estimate of lung cancer cases attributable to occupational exposure to asbestos.
RESULTS
the meta-analytical SMR for lung cancer in men varied between 1.05 (asphalt roll) and 2.36 (insulation). The mean risk for all sectors was 1.37 in men and 1.60 in women. It increased in cohorts with latency higher than 20 years. Significant risks were observed in asbestos-cement (both genders), construction, and mining sectors. There was a mean of 1.1, 2.7, and 2.8 lung cancer deaths per mesothelioma death in the cement-asbestos, harbour, and construction sectors, respectively. The impact in terms of lung cancer cases estimated at the national level was equal to 3,814 cases between 2010 and 2015.
CONCLUSIONS
to provide an overall assessment of the impact of the occupational asbestos exposure, it is important to consider lung cancer cases, in addition to malignant mesotheliomas. This study was able to estimate the impact of asbestos on lung cancer in Italy 25 years after the ban of this occupational carcinogen, with the largest contribution in terms of attributable cases coming from the construction sector. It is urgent to implement adequate information and prevention strategies, health surveillance of workers, and the appropriate legal framework for insurance purposes.

Meta-Analysis
BACKGROUND
Thymic peptides (TPs) are often used to control malignant pleural effusion (MPE). So, we performed a clustered systematic review and meta-analysis to clarify the treatment regimens of TPs for MPE, demonstrate their clinical effectiveness and safety, and reveal the indications and optimal usage for a desired effectiveness.
MATERIALS AND METHODS
We collected all trials of TPs for MPE from Chinese and English databases (from inception until May 2021). After evaluating their bias risk, we pooled the data from each regimen using the meta-analysis or descriptive analysis, and summarized the evidence quality using the Grading of Recommendation Assessment, Development and Evaluation approach (GRADE).
RESULTS
Thirty-four trials were clustered into TPs for MPE from lung cancer or miscellaneous tumors. The TPs combined with chemical agents were mainly used in MPE from lung cancer. All five regimens, only thymosin with oxaliplatin (L-OHP) significantly improved the complete response (CR) [2.40 (1.84 to 3.13)], quality of life [2.04 (1.20 to 3.48)], 0.5- and 1-year overall survival (OS) rate [5.75 (3.02 to 10.92) and 5.29, (1.71 to 16.36)]. It also up-regulated the T lymphocyte levels, and reduced the pleurodesis failure, disease progression and adverse events. In patients with moderate to large volume, Karnofsky Performance Status score ≥ 50 or anticipated survival time ≥ 3 months, the thymosin (300 mg/time, one time/week and lasting two to eight times) with oxaliplatin (100 mg/m) achieved a desired response. Most results were moderate quality.
CONCLUSIONS
The current evidences indicate that the TPs are important pleurodesis agents, which combination with chemical agents are mainly used in MPE from lung cancer. The thymosin with L-OHP is a main regimen, which shows a significant improvement in clinical responses, antitumor immunity, and with a reasonable security. The evidence also provides indications and optimal usage for achieving a desired effectiveness.

BACKGROUND
Cellular immunotherapy has become a new and promising treatment for patients with liver tumor. However, as most immune cells are delivered by intravenous injection, the effect is limited and is likely to produce systemic toxicity. Here, the objective was to investigate the efficacy and safety of cellular immunotherapy by local infusion, which seems to be a promising approach and has not been well-studied.
METHODS
The PubMed, Web of Science, Embase, and Cochrane Library databases were searched to obtain literature. The overall response rate (ORR), overall survival (OS) rates, and adverse events were investigated to evaluate the effectiveness and safety of locoregional therapy. The methodological quality of the articles was assessed using the methodological index for non-randomized studies (MINORS) score. The meta-analysis was performed using Stata 15.0.
RESULTS
The eligible 17 studies involved a total of 318 patients. The random-effects model demonstrated that the ORR of local cell infusion therapy was 48% (95% confidence interval [CI]: 26%-70%). The pooled OS rate was 94% (95% CI: 83%-100%) at 6 months, 87% (95% CI: 74%-96%) at 12 months, and 42% (95% CI: 16%-70%) at 24 months. Subgroup analyses suggested that minimally invasive treatment and absence of metastasis were significantly associated with better ORR. Fourteen studies reported a variety of adverse events related to cell therapy by local perfusion. The most common complications after regional infusion of immune cells were myelosuppression (66%), fever (50%), gastrointestinal toxicity (22%), hepatic dysfunction (15%), and pleural effusion and/or ascites (14%).
CONCLUSIONS
Immune cell therapy through local perfusion is effective for patients with liver cancer, with manageable toxicity. It demonstrates better prognosis when combined with minimally invasive therapy. Considering the potential limitations, more randomized controlled trials are needed to provide solid evidence for our findings.

Review
Volatile organic compounds (VOCs) have shown potential as non-invasive breath biomarkers for lung cancer, but their unclear biological origin currently limits clinical applications. This systematic review explores headspace analysis of VOCs in patient-derived body fluids and lung cancer cell lines to pinpoint lung cancer-specific VOCs and uncover their biological origin. A search was performed in the databases MEDLINE and Web of Science. Twenty-two articles were included in this systematic review. Since there is no standardised approach to analyse VOCs, a plethora of techniques and matrices/cell lines were explored, which is reflected in the various VOCs identified. However, comparing VOCs in the headspace of urine, blood and pleural effusions from patients and lung cancer cell lines showed some overlapping VOCs, indicating their potential use in lung cancer diagnosis. This review demonstrates that VOCs are promising biomarkers for lung cancer. However, due to lack of inter-matrix consensus, standardised prospective trials will have to be conducted to validate clinically relevant biomarkers.

Meta-Analysis
BACKGROUND
Malignant pleural mesothelioma (MPM) poses diagnostic challenges due to its resemblance to benign pleural pathologies and different histological subtypes. Several immunohistochemistry markers have been employed to aid in accurate diagnosis.
METHODS
The present systematic review and meta-analysis aimed to assess the diagnostic performance of various immunohistochemistry markers in malignant pleural mesothelioma diagnosis and its histological subtypes. Following the PRISMA guidelines, we systematically searched the literature for articles on using different immunohistochemical markers in MPM and its histological subtypes. EMBASE, LILACS, MEDLINE, and Virtual Health Library were searched for studies published up to August 2023. We used the QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies) criteria to assess the quality of the included articles. Meta-analyses were performed to determine prevalence using a random-effects model.
RESULTS
103 studies met the inclusion criteria, comprising a diverse range of immunohistochemistry markers. EMA and desmin-loss exhibited high sensitivity (96% and 92%, respectively) in distinguishing malignant pleural mesothelioma from benign pleural pathologies. Specificity was notably high for both BAP1-loss and survivin expression at 100%. Subtype-specific analyses demonstrated that EMA and HEG1 were sensitive markers for epithelioid mesothelioma, while GLUT1 showed high sensitivity for sarcomatoid mesothelioma. In cases comparing epithelioid mesothelioma and lung adenocarcinoma, CAM5.2 and calretinin displayed high sensitivity, while WT1 and BAP1-loss demonstrated exceptional specificity for malignant epithelioid mesothelioma. In the case of sarcomatoid mesothelioma and sarcomatoid lung carcinoma, GATA3 exhibited the most heightened sensitivity, while GATA3 and D2-40 displayed the best specificity for sarcomatoid malignant mesothelioma diagnosis.
CONCLUSION
Immunohistochemistry markers are essential in accurately diagnosing malignant pleural mesothelioma and its histological subtypes. This systematic review and meta-analysis provide a comprehensive insight into the diagnostic performance of these markers, facilitating their potential clinical utility in the discrimination of malignant pleural mesothelioma from other pleural pathologies and the differentiation of malignant pleural mesothelioma subtypes.

Meta-Analysis Review
BACKGROUND
Ionizing radiation and mesothelioma have been examined among personnel employed in nuclear power plant and patients treated by external beam radiation therapy (EBRT). The association is still controversial; the purpose of this review is to summarize the scientific evidence published in the literature regarding the relationship between ionizing radiation and incidence of mesothelioma and, if possible, estimating strongness of the association by meta-analysis of extracted data.
METHODS
Articles included in the systematic review were retrieved by searching among the three main scientific databases: PubMed, Scopus, and Embase. The literature search was conducted in June 2021. A meta-analysis of random effects was conducted, stratified by exposure (EBRT, occupational exposure). The heterogeneity of the summary relative risks (RRs) was assessed using I statistics. Publication bias was evaluated graphically through the funnel plot.
FINDINGS
The exposure to ionizing radiation could be a risk factor for mesothelioma: both for exposure to high doses for short periods (EBRT) (RR of 3.34 [95% confidence interval, CI 1.24-8.99]) and for exposure to low doses for a prolonged duration (exposure working) (RR of 3.57 [95% CI 2.16-5.89]).
CONCLUSIONS
Despite the low number of mesotheliomas in the general population, the steadily increased risk among individuals exposed to radiation is still worth considering.

The current cost of treatment of malignant pleural effusion (MPE) with an indwelling pleural catheter (IPC) is unclear. We propose a review of the scientific evidence on the cost and effectiveness of this therapeutic option. Systematic review of the literature on the cost and effectiveness of the treatment of MPE by IPC, according to the PRISMA methodology and quality according to the scientific guidelines. A total of 4 articles, 152 patients, and 159 IPCs were included. The use of IPC was associated with improvement in symptoms and quality of life. The most common complications were infections (empyema in 20.9% of patients and cellulitis in 17.3%); 9% of cases were hospitalized due to complications, and <2% required subsequent procedures. The average cost of IPC (set/drainage bottles) ranged from €2,025.6 to €1,200.5 if it was placed on an outpatient basis, €1,100 if survival was <6 weeks, and €4,028 in patients with mesothelioma. Complications increased the cost, and taking into account follow-up visits, additional tests, and days of admission for complications, the cost was >€5,000. Compared with pleurodesis, the cost of IPC was significantly lower when patient survival was <14 weeks, but not when survival was longer or home care was required. The use of IPC is associated with good control of MPE and seldom requires many subsequent procedures; however, it is also associated with a certain rate of complications, which may increase costs. However, ambulatory management may help reduce costs, which are directly related to the type of tumor, the duration of survival, and the need for specialized treatment.

Meta-Analysis
PURPOSE
The purpose of this study is to study the clinical outcomes of different types of magnetic resonance (MR)-guided ablation for the treatment of liver tumors by performing a systematic review and pooled analysis.
MATERIALS AND METHODS
A comprehensive literature search was performed for clinical trials published from January 1997 to October 2019 in PubMed, the Web of Science, Embase, and the Cochrane Library. Pooled analyses were performed to obtain the complete ablation (CA), complication, progression-free survival (PFS), and overall survival (OS) rates.
RESULTS
Thirty studies were eligible, including four studies on MR-guided microwave ablation (MWA); 14 studies on MR-guided radiofrequency ablation (RFA); one study on both MR-guided MWA and RFA; eight studies on MR-guided, laser-induced thermotherapy (LITT); two studies on MR-guided percutaneous cryoablation (PC); and one study on MR-guided percutaneous ethanol injection (PEI). The CA rates in patients who underwent RFA, MWA, LITT, PC, and PEI were 95.60%, 98.86%, 77.78%, 47.92%, and 85.71%, respectively. The most frequent complications were pain (27.66%, 13/47) and postablation syndrome (27.66%, 13/47) in the PC group; pleural effusion (8.11%, 119/1,468) and subcapsular hematoma (2.25%, 33/1,468) in the LITT group; pleural effusion (2.67%, 2/75) in the MWA group; and subcapsular hematoma (4.18%, 20/478) and post-ablation syndrome (2.93%, 14/478) in the RFA group. There were few studies reporting PFS and OS.
CONCLUSIONS
MR-guided ablation is a practicable alternative treatment for liver tumors, especially MR-guided RFA and MWA, which have high rates of CA and low occurrences of complications.

Palliative Medicine Jun 2021People with mesothelioma and their families have palliative care needs throughout the relatively short trajectory of their illness.
BACKGROUND
People with mesothelioma and their families have palliative care needs throughout the relatively short trajectory of their illness.
AIM
To describe the palliative care needs and experiences of people with mesothelioma and their family carers.
DESIGN
Integrative systematic review with narrative synthesis (PROSPERO: CRD42020190115).
DATA SOURCES
MEDLINE, CINAHL, PsycINFO and the Cochrane Library were searched for articles published between 01 January 2000 and 10 May 2020. Articles were included if they presented empirical studies or comprehensive reviews including information about the palliative care needs and experiences of people with mesothelioma and their family carers.
RESULTS
The search yielded 508 articles, 14 were included in the analysis. A cross cutting theme of 'uncertainty' was identified encompassing five themes: (1) organisation and co-ordination of services, (2) communication and information needs, (3) management of care needs and high symptom burden, (4) consideration of the impact of seeking compensation and (5) family carer needs. Our findings demonstrate that people with mesothelioma want a co-ordinated, team-based approach to palliative care with a named point of contact. Whilst carers value and benefit from early referral to specialist palliative care, this does not necessarily reflect the outcomes and views of patients.
CONCLUSION
The evidence base around the palliative care needs and experiences of people with mesothelioma and their carers needs to be strengthened. The results of this review support the need to develop a greater understanding about the role non-specialist palliative care clinicians' play in providing generalist palliative care for people with mesothelioma and their carers.
