Endosonography With or Without Confirmatory Mediastinoscopy for Resectable Lung Cancer:A Randomized Clinical Trial

PURPOSE:Resectable non-small-cell lung cancer (NSCLC) with a high probability of mediastinal nodal involvement requires mediastinal staging by endosonography and, in the absence of nodal metastases, confirmatory mediastinoscopy according to current guidelines. However, randomized data regarding immediate lung tumor resection after systematic endosonography versus additional confirmatory mediastinoscopy before resection are lacking.METHODS:Patients with (suspected) resectable NSCLC and an indication for mediastinal staging after negative systematic endosonography were randomly assigned to immediate lung tumor resection or confirmatory mediastinoscopy followed by tumor resection. The primary outcome in this noninferiority trial (noninferiority margin of 8% that previously showed to not compromise survival, Pnoninferior &lt;.0250) was the presence of unforeseen N2 disease after tumor resection with lymph node dissection. Secondary outcomes were 30-day major morbidity and mortality.RESULTS:Between July 17, 2017, and October 5, 2020, 360 patients were randomly assigned, 178 to immediate lung tumor resection (seven dropouts) and 182 to confirmatory mediastinoscopy first (seven dropouts before and six after mediastinoscopy). Mediastinoscopy detected metastases in 8.0% (14/175; 95% CI, 4.8 to 13.0) of patients. Unforeseen N2 rate after immediate resection (8.8%) was noninferior compared with mediastinoscopy first (7.7%) in both intention-to-treat (Δ, 1.03%; UL 95% CIΔ, 7.2%; Pnoninferior =.0144) and per-protocol analyses (Δ, 0.83%; UL 95% CIΔ, 7.3%; Pnoninferior =.0157). Major morbidity and 30-day mortality was 12.9% after immediate resection versus 15.4% after mediastinoscopy first (P =.4940).CONCLUSION:On the basis of our chosen noninferiority margin in the rate of unforeseen N2, confirmatory mediastinoscopy after negative systematic endosonography can be omitted in patients with resectable NSCLC and an indication for mediastinal staging.</p

Pulmonary metastasectomy with lymphadenectomy for colorectal pulmonary metastases: A systematic review

BACKGROUND: Routine lymphadenectomy during metastasectomy for pulmonary metastases of colorectal cancer has been recommended by several recent expert consensus meetings. However, evidence supporting lymphadenectomy is limited. The aim of this study was to perform a systematic review of the literature on the impact of simultaneous lymph node metastases on patient survival during metastasectomy for colorectal pulmonary metastases (CRPM). METHODS: A systematic review was conducted according to the PRISMA guidelines of studies on lymphadenectomy during pulmonary metastasectomy for CRPM. Articles published between 2000 and 2020 were identified from Medline, Embase and the Cochrane Library without language restriction. Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework was used to assess the risk of bias and applicability of included studies. Survival rates were assessed and compared for the presence and level of nodal involvement. RESULTS: Following review of 8054 studies by paper and abstract, 27 studies comprising 3619 patients were included in the analysis. All patients included in these studies underwent lymphadenectomy during pulmonary metastasectomy for CRPM. A total of 690 patients (19.1%) had simultaneous lymph node metastases. Five-year overall survival for patients with and without lymph node metastases was 18.2% and 51.3%, respectively (p < .001). Median survival for patients with lymph node metastases was 27.9 months compared to 58.9 months in patients without lymph node metastases (p < .001). Five-year overall survival for patients with N1 and N2 lymph node metastases was 40.7% and 10.9%, respectively (p = .064). CONCLUSION: Simultaneous lymph node metastases of CRPM have a detrimental impact on survival and this is most apparent for mediastinal lymph node metastases. Therefore, lymphadenectomy during pulmonary metastasectomy for CRPM can be advised to obtain important prognostic value

Unforeseen N2 Disease after Negative Endosconography Findings with or without Confirmatory Mediastinoscopy in Resectable Non–Small Cell Lung Cancer: A Systematic Review and Meta-Analysis

Introduction: Confirmatory mediastinoscopy after negative endosonography findings is advised by the guidelines on patients with resectable NSCLC and suspected intrathoracic nodes on fludeoxyglucose F 18 positron emission tomography–computed tomography. Its role however is under debate owing to its limited nodal metastasis detection rate, morbidity, associated treatment delay, and unknown impact on survival. Methods: Systematic review and meta-analysis of studies on invasive mediastinal staging in patients with (suspected)NSCLC. The Medline, Embase, and Cochrane databases were searched until September 19, 2018, without year or language restrictions. The Quality Assessment Tool for Diagnostic Accuracy Studies, version 2, was used to evaluate the risk of bias and applicability of the included studies. Rates of unforeseen N2 disease were assessed for endobronchial ultrasound and/or endoscopic ultrasound staging strategies with or without confirmatory mediastinoscopy. Additionally, the complication rates of cervical video mediastinoscopy for mediastinal staging of NSCLC were investigated. Results: A total of 5073 articles were found, of which 42 studies or subgroups (covering a total of 3248 patients undergoing the surgical reference standard of treatment)were considered in the analysis. Random effects meta-analysis of endosonography with or without confirmatory mediastinoscopy showed rates of unforeseen N2 disease of 9.6% (95% confidence interval [CI]: 7.8%–11.7%, I 2 = 30%)versus 9.9% (95% CI: 6.3%–15.2%, I 2 = 73%), respectively. Random effects meta-analysis of mediastinoscopy (eight studies [1245 patients in total])showed a complication rate of 6.0% (95% CI: 4.8%–7.5%), with laryngeal recurrent nerve palsy accounting for 2.8% (95% CI: 2.0%–4.0%). Conclusion: The rate of unforeseen N2 disease after negative endosonography findings was similar in patients undergoing immediate lung tumor resection to those undergoing confirmatory mediastinoscopy first, at the cost of 6.0% rate of complications by mediastinoscopy

Development of a Core Set of Patient- and Caregiver-Reported Signs and Symptoms to Facilitate Early Recognition of Acute Chimeric Antigen Receptor T-Cell Therapy Toxicities

PURPOSE: Prompt recognition of acute chimeric antigen receptor T (CAR T)-cell-mediated toxicities is crucial because adequate and timely management can prevent or reverse potential life-threatening complications. In the outpatient setting, patients and informal caregivers have to recognize and report signs and symptoms marking these acute toxicities. This study provides a core set of patient- and caregiver-reported signs and symptoms (outcomes, P/CROs) and definitions of red flags warranting immediate action to include in a daily checklist for support at home, with the goal to make outpatient post-CAR T-cell care safer, optimize patient and caregiver support, and thereby facilitating an early discharge/hospital visit reduction strategy. METHODS: We performed a systematic review of phase II/III trials of US Food and Drug Administration-approved CAR T-cell products and selected all common and severe adverse events that could be translated into a P/CRO for inclusion in a two-round modified Delphi procedure. Eleven CAR T-cell-dedicated hematologists from the Dutch CAR T-cell tumorboard representing all treating centers selected P/CROs for inclusion in the core set and defined red flags. The final core set was evaluated with patients and caregivers. RESULTS: From nine clinical trials, 457 adverse events were identified of which 42 could be used as P/CRO. The final core set contains 28 items, including five signs for measurement via wearables and two signs for caregiver-performed assessments. CONCLUSION: This study provides a core set of P/CROs that can serve as a framework for (eHealth) tools that aim to enable patients and caregivers to more effectively recognize and report signs and symptoms of acute toxicities after CAR T-cell therapy, which will enhance safe outpatient treatment monitoring

Early detection of obstructive coronary artery disease in the asymptomatic high-risk population: objectives and study design of the EARLY-SYNERGY trial

Background: Coronary artery disease (CAD) burden for society is expected to steeply increase over the next decade. Improved feasibility and efficiency of preventive strategies is necessary to flatten the curve. Acute myocardial infarction (AMI) is the main determinant of CAD-related mortality and morbidity, and predominantly occurs in individuals with more advanced stages of CAD causing subclinical myocardial ischemia (obstructive CAD; OCAD). Unfortunately, OCAD can remain subclinical until its destructive presentation with AMI or sudden death. Current primary preventive strategies are not designed to differentiate between non-OCAD and OCAD and the opportunity is missed to treat individuals with OCAD more aggressively. Methods: EARLY-SYNERGY is a multicenter, randomized-controlled clinical trial in individuals with coronary artery calcium (CAC) presence to study (1.) the yield of cardiac magnetic resonance stress myocardial perfusion imaging (CMR-MPI) for early OCAD diagnosis and (2) whether early OCAD diagnosis improves outcomes. Individuals with CAC score ≥300 objectified in 2 population-based trials (ROBINSCA; ImaLife) are recruited for study participation. Eligible candidates are randomized 1:1 to cardiac magnetic resonance stress myocardial perfusion imaging (CMR-MPI) or no additional functional imaging. In the CMR-MPI arm, feedback on imaging results is provided to primary care provider and participant in case of guideline-based actionable findings. Participants are followed-up for clinical events, healthcare utilization and quality of life. Conclusions: EARLY-SYNERGY is the first randomized-controlled clinical trial designed to test the hypothesis that subclinical OCAD is widely present in the general at-risk population and that early differentiation of OCAD from non-OCAD followed by guideline-recommended treatment improves outcomes

Guideline adherence of mediastinal staging of non-small cell lung cancer:A multicentre retrospective analysis

Objectives: Mediastinal lymph node staging of NSCLC by initial endosonography and confirmatory mediastinoscopy is recommended by the European guideline. We assessed guideline adherence on mediastinal staging, whether staging procedures were performed systematically and unforeseen N2 rates following staging by endosonography with or without confirmatory mediastinoscopy. Material and Methods: We performed a multicentre (n = 6) retrospective analysis of NSCLC patients without distant metastases, who were surgical candidates and had an indication for mediastinal staging in the year 2015. All patients who underwent EBUS, EUS and/or mediastinoscopy were included. Surgical lymph node dissection was the reference standard. Guideline adherence was based on the 2014 ESTS guideline. Results: 330 consecutive patients (mean age 69 years; 61% male) were included. The overall prevalence of N2/N3 disease was 42%. Initial mediastinal staging by endosonography was done in 84% (277/330; range among centres 71-100%; p <.01). Confirmatory mediastinoscopy was performed in 40% of patients with tumour negative endosonography (61/154; range among centres 10%-73%; p <.01). Endosonography procedures were performed ‘systematically’ in 21% of patients (57/277) with significant variability among centres (range 0-56%; p <.01). Unforeseen N2 rates after lobe-specific lymph node dissection were 8.6% (3/35; 95%-CI 3.0-22.4) after negative endosonography versus 7.5% (3/40; 95% CI 2.6-19.9) after negative endosonography and confirmatory mediastinoscopy. Conclusion: Although adherence to the European NSCLC mediastinal staging guideline on initial use of endosonography was good, 30% of endosonography procedures were performed insufficiently. Confirmatory mediastinoscopy following negative endosonography was frequently omitted. Significant variability was found among participating centres regarding staging strategy and systematic performance of procedures. However, unforeseen N2 rates after mediastinal staging by endosonography with and without confirmatory mediastinoscopy were comparable
