Meta-Analysis
BACKGROUND
Mediastinal restaging after induction treatment is still a difficult and controversial issue. We aimed to investigate the diagnostic accuracy of endobronchial ultrasound-guided transbronchial needle aspiration and endoscopic ultrasound-guided fine-needle aspiration for restaging the mediastinum after induction treatment in patients with lung cancer.
METHODS
Embase and PubMed databases were searched from conception to March 2019. Data from relevant studies were analyzed to assess sensitivity and specificity of endobronchial ultrasound-guided transbronchial needle aspiration and endoscopic ultrasound-guided fine-needle aspiration, and to fit the hierarchical summary receiver operating characteristic curves.
RESULTS
A total of 10 studies consisting of 558 patients fulfilled the inclusion criteria. All patients were restaged by endobronchial ultrasound-guided transbronchial needle aspiration, endoscopic ultrasound-guided fine-needle aspiration, or both. Negative results were confirmed by subsequent surgical approaches. There were no complications reported during any endosonography approaches reviewed. The pooled sensitivities of endobronchial ultrasound-guided transbronchial needle aspiration and endoscopic ultrasound-guided fine-needle aspiration were 65% (95% confidence interval [CI], 52-76) and 73% (95% CI, 52-87), respectively, and specificities were 99% (95% CI, 78-100) and 99% (95% CI, 90-100), respectively. The area under the hierarchical summary receiver operating characteristic curves were 0.85 (95% CI, 0.81-0.88) for endobronchial ultrasound-guided transbronchial needle aspiration and 0.99 (95% CI, 0.98-1) for endoscopic ultrasound-guided fine-needle aspiration. Moreover, for patients who received chemotherapy alone, the pooled sensitivity of endosonography with lymph node sampling for restaging was 66% (95% CI, 56-75), and specificity was 100% (95% CI, 34-100); for patients who received chemoradiotherapy, the results seemed similar with a sensitivity of 77% (95% CI, 47-92) and specificity of 99% (95% CI, 48-100).
CONCLUSIONS
Endosonography with lymph node sampling is an accurate and safe technique for mediastinal restaging of lung cancer.

Meta-Analysis Comparative Study Review
A systematic review and meta-analysis were performed to investigate the efficacy of the AirSeal Valveless Trocar Needle Insufflation System in robot-assisted partial nephrectomy (RAPN). The study compared the differences in perioperative outcomes between the AirSeal insufflation group (AIS) and the conventional insufflation group (CIS). A systematic search of databases such as PubMed, Embase, Cochrane library, and Web of science was performed to identify studies reporting perioperative outcomes between the AirSeal insufflation group (AIS) and the conventional insufflation group (CIS) in RAPN. The study protocol is registered with PROSPERO (CRD42024524335). The primary outcome was to compare the incidence of subcutaneous emphysema (SCE) and postoperative pain scores between the two approaches. The review included four studies with 379 patients, 194 in the AIS group and 185 in the CIS group. Baseline characteristics of the two groups were similar in all outcomes. SCE was significantly lower in the AIS group than in the CIS group [(OR) 0.30 (0.16, 0.54), p < 0.001]. Postoperative 12-h pain scores were also significantly lower in the AIS group compared to the CIS group [(WMD) - 0.93 (- 1.67, - 1.09), p = 0.014]. Both groups showed a significant reduction in length of hospitalization [(WMD) - 0.12 (- 0.84, 0.60), p = 0.746], thermal ischemia time [(WMD) 4.72 (- 5.71, 15.15), p = 0.375], amount of lost hemoglobin [(WMD) - 0.19 (- 0.53, 0.15), p = 0.284], pneumothorax [(OR) 0.13 (0.02,1.10), p = 0.062], mediastinal emphysema [(OR) 0.55 (0.20, 1.46), p = 0.230], and 4-h pain score [(WMD) - 0.25 (- 1.16, 0.65), p = 0.584]; no significant differences were observed. The incidence of subcutaneous emphysema SCE and 12-h pain scores were significantly lower in the AIS group compared to the CIS group. The AirSeal system demonstrated similar efficacy and a higher safety profile than the conventional insufflation system in robotic-assisted partial nephrectomy; however, due to the lack of a randomized study on the topic, further data are needed.

Impact of Rapid On-Site Cytological Evaluation (ROSE) on the Diagnostic Yield of Transbronchial Needle Aspiration During Mediastinal Lymph Node Sampling: Systematic Review and Meta-Analysis.
BACKGROUND
Whether the use of rapid on-site cytologic evaluation (ROSE) increases the diagnostic yield of transbronchial needle aspiration (TBNA) remains unclear. This article is a systematic review of studies describing the utility of ROSE in subjects undergoing TBNA.
METHODS
The study included a systematic review of the PubMed, Embase, and Scopus databases for randomized controlled trials investigating the diagnostic yield of conventional transbronchial needle aspiration (c-TBNA) or endobronchial ultrasound (EBUS)-TBNA, with or without ROSE, in subjects with mediastinal lymphadenopathy.
RESULTS
Five studies (618 subjects; two EBUS-TBNA, two c-TBNA, and one both) were identified. Overall, the studies were of good quality. The pooled risk difference (95% CI) of the diagnostic yield of EBUS-TBNA and c-TBNA was 0.04 (-0.01 to 0.09) and 0.12 (-0.08 to 0.33), respectively, suggesting no added benefit with ROSE. The use of ROSE during EBUS-TBNA (but not c-TBNA) resulted in significantly fewer needle passes (mean difference [95% CI], -1.1 [-2.2 to -0.005]; P < .001). There was no difference in the procedure time during EBUS-TBNA. The complication rate was significantly lower (OR [95% CI], 0.26 [0.10 to 0.71]; P = .009) when ROSE was used during c-TBNA due to fewer additional procedures required to make a diagnosis. There was evidence of heterogeneity in the studies involving c-TBNA but not EBUS-TBNA. There was no publication bias.
CONCLUSIONS
The use of ROSE neither improved the diagnostic yield nor reduced the procedure time during TBNA. However, the use of ROSE was associated with fewer number of needle passes during EBUS-TBNA and overall lower requirement for additional bronchoscopy procedures during TBNA to make a final diagnosis.

Comparing diagnostic sensitivity of different needle sizes for lymph nodes suspected of lung cancer in endobronchial ultrasound transbronchial needle aspiration: Systematic review and meta-analysis.
BACKGROUND
Endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) is a safe and minimally invasive procedure for evaluating hilar and mediastinal lymph nodes. The reported sensitivity and specificity of EBUS-TBNA are 95% and 97%, respectively. A comparison of diagnostic sensitivity for lymph nodes suspected of lung cancer according to needle size in EBUS-TBNA is needed.
OBJECTIVES
To compare the diagnostic sensitivity of the 19-G, 21-G, 22-G and 25-G needles for lymph nodes suspected of non-small cell lung cancer (NSCLC) using EBUS-TBNA.
METHODS
A literature search from PubMed, EMBASE, LILACS, DOAJ and CENTRAL through October 2020 was performed by two reviewers. The extracted data were evaluated using STATA® and Open Meta Analyst software for meta-analysis with a binary method model to compare sensitivity, specificity and summary receiver operating characteristic curve for each needle size.
RESULTS
Fourteen studies including 1296 participants were considered for the analysis. The overall sensitivity of EBUS-TBNA was 88.2% (95% CI 84%, 91%) and 93% (95% CI 88%, 95%) for the 19-G needle, 87.6% (95% CI 79.6%, 92.8%) for the 21-G needle and 85% (95% CI 80%, 88%) for the 22-G needle. The overall sensitivity of EBUS-TBNA for diagnosing NSCLC was 88.3% (95% CI, 81%, 93%) and 92.9% (95% CI, 85%, 97%) for the 19-G needle, 89.4% (95% CI 79.4%, 94.8%) for the 21-G needle and 82.1% (95% CI 66%, 91%) for the 22-G needle.
CONCLUSION
The 19-G, 21-G and 22-G needles present a similarly high diagnostic sensitivity in EBUS-TBNA. The 19-G needle provided better sample adequacy for molecular and immunohistochemical testing, improving diagnostic yield in this subgroup.

PURPOSE
Primary mediastinal B cell lymphoma (PMBCL) is a highly curable subtype of non-Hodgkin lymphoma that is diagnosed predominantly in adolescents and young adults. Consequently, long-term treatment-related morbidity is critical to consider when devising treatment strategies that include different chemoimmunotherapy strategies with or without radiation therapy. Furthermore, adaptive approaches using the end-of-chemotherapy (EOC) positron emission tomography (PET)/computed tomography (CT) scanning may help to determine which patients may benefit from additional therapies. We aimed to develop evidence-based guidelines for treating these patients.
METHODS AND MATERIALS
We conducted a systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline using the PubMed database. The ARS expert committee, composed of radiation oncologists, hematologists, and pediatric oncologists, developed consensus guidelines using the modified Delphi framework.
RESULTS
Nine studies met the full criteria for inclusion based on reporting outcomes on patients with primary mediastinal B cell lymphoma with EOC PET/CT response scored with the 5-point Deauville scale. These studies formed the evidence for these guidelines in managing patients with PMBCL according to the EOC PET response, including after a 5-point Deauville scale of 1 to 3, 4, or 5, and for patients with relapsed and refractory disease. The expert group also developed guidance on radiation simulation, treatment planning, and plan evaluation based on expert opinion.
CONCLUSIONS
Various treatment approaches exist in the management of PMBCL, including different chemoimmunotherapy regimens, the use of consolidative radiation therapy, and adaptive approaches based on EOC PET/CT response. These guidelines can be used by practitioners to provide appropriate treatment according to different disease scenarios.

INTRODUCTION
Synchronous oligometastatic (sOM) disease is an oncological concept characterized by a limited cancer burden. Patients with oligometastasis could potentially benefit from local radical treatments. Despite the fact that the sOM condition is well recognized, a universal definition, including a specific definition for NSCLC, is not yet available. The aim of this systematic review was to summarize the definitions of and staging requirements for use of the term synchronous oligometastatic in the context of NSCLC.
METHODS
The key issue was formulated in one research question according to the population, intervention, comparator, and outcomes strategy. The question was introduced in MEDLINE (OvidSP). All articles dealing with sOM NSCLC and providing a definition of synchronous oligometastasis in NSCLC were selected and analyzed.
RESULTS
A total of 21 eligible articles focusing on sOM NSCLC were retrieved and analyzed. In 17 studies (81%), patients had to be staged with magnetic resonance imaging or computed tomography of the brain, thoracic and abdominal computed tomography, and positron emission tomography. The total number of metastases allowed in the definitions ranged from one to eight, but in 38.1% of studies the maximum number was 5. Most of the publications did not define the number of involved organs or the maximum number of metastases per organ. For mediastinal lymph node involvement, only five articles (27.8%) counted this as a metastatic site.
CONCLUSIONS
No uniform definition of sOM NSCLC could be retrieved by this systematic review. However, extended staging was mandated in most of the studies. An accepted oncological definition of synchronous oligometastasis is essential for patient selection to define prospective clinical trials.

Meta-Analysis
Elevated preoperative CEA is associated with subclinical nodal involvement and worse survival in stage I non-small cell lung cancer: a systematic review and meta-analysis.
BACKGROUND
The standard for clinical staging of lung cancer is the use of CT and PET scans, however, these may underestimate the burden of the disease. The use of serum tumor markers might aid in the detection of subclinical advanced disease. The aim of this study is to review the predictive value of tumor markers in patients with clinical stage I NSCLC.
METHODS
A comprehensive search was performed using the Medline, EMBASE, Scopus data bases. Abstracts included based on the following inclusion criteria: 1) adult ≥18 years old, 2) clinical stage I NSCLC, 3) Tumor markers (CEA, SCC, CYFRA 21-1), 4) further imaging or procedure, 5) > 5 patients, 6) articles in English language. The primary outcome of interest was utility of tumour markers for predicting nodal involvement and oncologic outcomes in patients with clinical stage I NSCLC. Secondary outcomes included sub-type of lung cancer, procedure performed, and follow-up duration.
RESULTS
Two hundred seventy articles were screened, 86 studies received full-text assessment for eligibility. Of those, 12 studies were included. Total of 4666 patients were involved. All studies had used CEA, while less than 50% used CYFRA 21-1 or SCC. The most common tumor sub-type was adenocarcinoma, and the most frequently performed procedure was lobectomy. Meta-analysis revealed that higher CEA level is associated with higher rates of lymph node involvement and higher mortality.
CONCLUSION
There is significant correlation between the CEA level and both nodal involvement and survival. Higher serum CEA is associated with advanced stage, and poor prognosis. Measuring preoperative CEA in patient with early stage NSCLC might help to identify patients with more advanced disease which is not detected by CT scans, and potentially identify candidates for invasive mediastinal lymph node staging, helping to select the most effective therapy for patients with potentially subclinical nodal disease. Further prospective studies are needed to standardize the use of CEA as an adjunct for NSCLC staging.

Meta-Analysis
To compare computed tomography (CT)-based radiologic features in patients, who are diagnosed with lung adenocarcinoma with the pathologically detected spread of tumor cells through air spaces (STAS positive [STAS+]) and those with no STAS. PubMed, Embase, and Scopus databases were systematically searched for observational studies (either retrospective or prospective) of patients with lung adenocarcinoma that had compared CT-based features between STAS+ and STAS-negative cases (STAS-). The pooled effect sizes were reported as odds ratio (OR) and weighted mean difference (WMD). STATA software was used for statistical analysis. The meta-analysis included 10 studies. Compared with STAS-, STAS+ adenocarcinoma was associated with increased odds of solid nodule (OR: 3.30, 95% CI: 2.52, 4.31), spiculation (OR: 2.05, 95% CI: 1.36, 3.08), presence of cavitation (OR: 1.49, 95% CI: 1.00, 2.22), presence of clear boundary (OR: 3.01, 95% CI: 1.70, 5.32), lobulation (OR: 1.65, 95% CI: 1.11, 2.47), and pleural indentation (OR: 1.98, 95% CI: 1.41, 2.77). STAS+ tumors had significant association with the presence of pulmonary vessel convergence (OR: 2.15, 95% CI: 1.61, 2.87), mediastinal lymphadenopathy (OR: 2.06, 95% CI: 1.20, 3.56), and pleural thickening (OR: 2.58, 95% CI: 1.73, 3.84). The mean nodule diameter (mm) (WMD: 6.19, 95% CI: 3.71, 8.66) and the mean solid component (%) (WMD: 24.5, 95% CI: 10.5, 38.6) were higher in STAS+ tumors, compared with STAS- ones. The findings suggest a significant association of certain CT-based features with the presence of STAS in patients with lung adenocarcinoma. These features may be important in influencing the nature of surgical management.

BACKGROUND AND AIMS
Postoperative esophageal leaks are one of the major causes of postoperative mortality and morbidity. The purpose of this study was to review current knowledge of current methods of diagnosis and management of postoperative esophageal leaks. A systematic literature search was performed in the PubMed/Medline database using the terms "postoperative esophageal leaks" and "postesophagectomy complications" to identify articles relevant to the current diagnostic and prophylactic and curative treatment of post-oesophagectomy anastomotic fistulas. Several papers have shown that the incidence of fistulas varies and is dependent on several factors: the location of the anastomosis, the type of suture used, the biological condition of the patient. Due to the severity of the mediastinal anastomotic fistula, great importance is being given to the methods of preventing its occurrence by intraoperative testing or improving the gastric tube vascularity. The most recent articles present endoscopic methods of treating this complication by using coated esophageal stents and endoluminal vacuum therapy.
CONCLUSION
In patients with mediastinal postoperative esophageal fistulas, diagnosis and management represent a real challenge for the surgeon-endoscopist-therapist team. The early diagnosis and the establishment of an optimal therapy to address the parietal defect and the biological status of the patient are mandatory conditions for resolving this postoperative complication.

Endobronchial ultrasound-guided transbronchial needle aspiration versus mediastinoscopy for mediastinal staging of lung cancer: A systematic review of economic evaluation studies.
INTRODUCTION
The emergence of endobronchial ultrasound (EBUS) changed the approach to staging lung cancer. As a new method being incorporated, the use of EBUS may lead to a shift in clinical and costs outcomes.
OBJECTIVE
The aim of this systematic review is to gather information to better understand the economic impact of implementing EBUS.
METHODS
This review is reported according to the PRISMA statement and registered on PROSPERO (CRD42019107901). Search keywords were elaborated considering descriptors of terms related to the disease (lung cancer / mediastinal staging of lung cancer) and the technologies of interest (EBUS and mediastinoscopy) combined with a specific economic filter. The literature search was performed in MEDLINE, EMBASE, LILACS, Cochrane Library of Trials, Web of Science, Scopus and National Health System Economic Evaluation Database (NHS EED) of the Center for Reviews and Dissemination (CRD). Screening, selection of articles, data extraction and quality assessment were carried out by two reviewers.
RESULTS
Seven hundred and seventy publications were identified through the database searches. Eight articles were included in this review. All publications are full economic evaluation studies, one cost-effectiveness, three cost-utility, and four cost-minimization analyses. The costs of strategies using EBUS-TBNA were lower than the ones using mediastinoscopy in all studies analyzed. Two of the best quality scored studies demonstrate that the mediastinoscopy strategy is dominated by the EBUS-TBNA strategy.
CONCLUSION
Information gathered in the eight studies of this systematic review suggest that EBUS is cost-effective compared to mediastinoscopy for mediastinal staging of lung cancer.
