“…Controversially, other studies showed sensitivity or speci city of EBUS-elastography in the diagnosis of malignant lymph node were around 75% -87% or 65%-68% (Caglayan et al 2020;Fournier et al 2019). The discrepancy could be partly due to the different way to interpret the image results in EBUSelastography.…”

Background: Endobronchial ultrasound (EBUS) elastography has been applied in EBUS-guided transbronchial needle aspiration (EBUS-TBNA) to identify malignant lymph nodes based on the tissue stiffness. Rapid onsite cytological evaluation (ROSE) has been widely used for onsite evaluation of the adequacy of the samples and guiding the sampling during EBUS-TBNA. The aim of the study is to investigate the diagnostic value of combined EBUS elastography and ROSE in evaluating of mediastinal and hilar lymph nodes status.Methods: A retrospective chart review was performed from December 2018 to September 2020. Patients’ demographic, EBUS elastography score, ROSE, pathologic and clinical outcomes were collected. The EBUS elastography scores were classified as follows: Type 1, predominantly non-blue; Type 2, partially blue and partially non-blue; Type 3, predominantly blue. Receiver operating characteristic (ROC) curve was used to compare the sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio among EBUS elastography, ROSE, and EBUS combined with ROSE groups for evaluation of malignant lymph nodes.Results: A total of 247 patients (345 lymph nodes) were included in our study. The sensitivity and specificity of EBUS elastography group in the diagnosis of malignant lymph nodes were 90.51% and 57.26%, respectively. The sensitivity and specificity in the ROSE alone group were 96.32% and 79.05%, respectively. The sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio of EBUS elastography combined with ROSE group were 86.61%, 92.65%, 11.78, and 0.14, respectively, and the area under curve was 0.942.Conclusions: The combination of EBUS elastography and ROSE significantly increased the diagnostic value of EBUS-TBNA in evaluating mediastinal and hilar lymph nodes status.

“…A NPV of 100% demonstrated that EBUS elastography could decrease the number of unnecessary aspirations and the total examination time. Controversially, other studies have indicated approximately 75% to 87% sensitivity and 65% to 68% specificity of EBUS elastography in diagnosing malignant lymph nodes [ 30 , 31 ]. This discrepancy could be partly explained by different interpretations of the EBUS elastography images.…”

Conclusions Combining EBUS elastography and ROSE significantly increased the diagnostic value of EBUS-TBNA in evaluating mediastinal and hilar lymph node status compared to each method alone.

Aims: In the present study, a meta-analysis was performed to evaluate the diagnostic value of endobronchial ultrasound (EBUS) elastography for differentiating benign and malignant hilar and mediastinal lymph nodes (LNs). Material and methods: A comprehensive literature search was carried out through PubMed, Embase, and Cochrane Library. Two authors screened the papers and extracted the data independently and any discrepancies were resolved by discussion. The methodolog-ical quality of each included study was assessed by the Quality Assessment of Diagnostic Accuracy Studies 2 tool. Sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and area under the curve were calculated to evaluate the value of EBUS elastography for hilar and mediastinal LNs. Results: Seventeen studies with the number of 2307 LNs were included. There was significant heterogeneity across the included studies. The pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio for the diagnosis of hilar and mediastinal LNs by EBUS elastography were 0.90 (95% confidence interval [CI], 0.84-0.94), 0.78 (95% CI, 0.74-0.81), 4.1 (95% CI, 3.4-4.9), 0.12 (95% CI, 0.07-0.21) and 33 (95% CI, 17-64), respectively. Furthermore, area under the curve was calculated to be 0.86 (95% CI, 0.82-0.88). Conclusion: EBUS elastography is a valuable technology in the differentiation of benign and malignant hilar and mediastinal LNs and could provide supplementary diagnostic information during endobronchial ultrasound-guided transbronchial needle aspiration. The combination of EBUS elastography and B-mode EBUS could improve the diagnostic accuracy for hilar and mediastinal LNs.
