Pulmonology 2024; 30:459-465. [PMID: 38182468 DOI: 10.1016/j.pulmoe.2023.11.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 11/21/2023] [Accepted: 11/22/2023] [Indexed: 01/07/2024] Open
Abstract
BACKGROUND Endobronchial Ultrasound (EBUS) has emerged as a crucial tool for diagnosing intrathoracic disorders, particularly in the staging of lung cancer. However, its diagnostic capabilities in the context of benign and rare diseases remain a subject of debate. AIM to investigate the diagnostic yield and safety of EBUS-transbronchial mediastinal cryobiopsy (EBUS-TMC) in comparison to EBUS-transbronchial needle aspiration (TBNA) for a broad spectrum of intrathoracic diseases. METHODS a single-centre retrospective observational study conducted on 48 patients who underwent both EBUS-TBNA and endobronchial ultrasound-transbronchial mediastinal cryobiopsy (EBUS-TMC) in the same procedure between August 2021 and October 2023. RESULTS The overall diagnostic yield of EBUS-TMC surpassed that of EBUS-TBNA (95.8% vs 54.1 %), notably excelling in the diagnosis of sarcoidosis (92.8% vs 78.5 %), rare mediastinal disorders (100% vs 0 %), hyperplastic lymphadenopathy (100% vs 0 %), and lymphoproliferative disease (100% vs 0 %). No significant differences were observed in the diagnosis of NSCLC and SCLC. Samples obtained through EBUS-TMC facilitated the acquisition of NGS and immunohistochemical analyses more readily. CONCLUSION EBUS-TMC may contribute to the precise diagnosis and subtyping of mediastinal diseases, especially lymphomas and rare mediastinal tumors, thereby reducing the number of non-diagnostic procedures.

An explorative analysis on the optimal cryo-passes and freezing time of the ultrathin cryoprobe in endobronchial ultrasound-guided transbronchial mediastinal cryobiopsy. Sci Rep 2024; 14:18653. [PMID: 39134712 PMCID: PMC11319585 DOI: 10.1038/s41598-024-69702-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Accepted: 08/07/2024] [Indexed: 08/15/2024] Open
Abstract
EBUS-guided transbronchial mediastinal cryobiopsy (TBMC) has emerged as a promising biopsy tool for diagnosing hilar and mediastinal pathologies. However, several fundamental technical aspects of TBMC remain unexplored. This study aims to determine the optimal number of cryo-passes and freezing time of the ultrathin cryoprobe in EBUS-TBMC concerning specimen size and procedural diagnostic yield. We conducted a retrospective chart review of patients with mediastinal and hilar lesions who underwent EBUS-TBMC between January 2021 and April 2023 across three hospitals in Malaysia. A total of 129 EBUS-TBMC procedures were successfully completed, achieving an overall diagnostic yield of 88.4%. Conclusive TBMC procedures were associated with larger specimen sizes (7.0 vs. 5.0 mm, p < 0.01). Specimen size demonstrated a positive correlation with diagnostic yield (p < 0.01), plateauing at specimen size of 4.1-6.0 mm. A significant positive correlation was also observed between the number of cryo-passes and both specimen size (p < 0.01) and diagnostic yield (p < 0.05). Diagnostic yield plateaued after 2-3 cryo-passes. In contrast, longer freezing times trended towards smaller specimens and lower diagnostic yield, though not reaching statistical significance. The highest diagnostic yield was recorded at the 3.1-4.0 s freezing time. The safety profile of TBMC remains favourable, with one case (0.8%) of pneumothorax and nine cases (7%) of self-limiting bleeding. In our cohort, TBMC performance with 2-3 cryo-passes and a 3.1-4.0 s freezing time to achieve a total aggregate specimen size of 4.1-6.0 mm appeared optimal. Further prospective studies are needed to validate these findings.

Utility and safety of endobronchial ultrasound-guided transbronchial mediastinal cryobiopsy (EBUS-TMC): A systematic review and meta-analysis. Lung India 2024; 41:288-298. [PMID: 38953193 PMCID: PMC11302774 DOI: 10.4103/lungindia.lungindia_606_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 04/17/2024] [Accepted: 05/05/2024] [Indexed: 07/03/2024] Open
Abstract
BACKGROUND Modalities to improve tissue acquisition during endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) have been investigated. Endobronchial ultrasound-guided transbronchial mediastinal cryobiopsy (EBUS-TMC) is a modality to obtain larger histological samples by inserting a cryoprobe into the mediastinal lesion. We aimed to study the diagnostic yield and safety of EBUS-TMC. METHODS We performed a systematic search of the PubMed and Embase databases to extract the relevant studies. We then performed a meta-analysis to calculate the diagnostic yield of EBUS-TMC and compare it with EBUS-TBNA. RESULTS Following a systematic search, we identified 14 relevant studies (869 patients undergoing EBUS-TMC and EBUS-TBNA). We then performed a meta-analysis of the diagnostic yield of EBUS-TMC and EBUS-TBNA from studies wherein both procedures were performed. The pooled diagnostic yield of EBUS-TMC was 92% (95% confidence interval [CI], 89%-95%). The pooled diagnostic yield of EBUS-TBNA was 81% (95% CI, 77%-85%). The risk difference in yield was 11% (95% CI, 6%-15%, I2 = 0%) when EBUS-TMC and EBUS-TBNA were compared. The only complication reported commonly with EBUS-TMC was minor bleeding. The complication rate was comparable with EBUS-TBNA. CONCLUSION EBUS-TMC provides a greater diagnostic yield with a similar risk of adverse events compared to EBUS-TBNA. Future studies are required to clearly establish which patients are most likely to benefit from this modality.

Abstract
OBJECTIVE The present study assessed the diagnostic and prognostic significance of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for suspected intrathoracic metastasis after HNC treatment. METHODS A retrospective analysis was conducted on 75 patients with a prior history of head and neck cancer treatment who underwent EBUS-TBNA for suspected intrathoracic metastases between March 2012 and December 2021. RESULTS A total of 126 targeted lesions, including 107 mediastinal/hilar lymph nodes and 19 intrapulmonary/mediastinal masses, were sampled. The metastatic head and neck cancer (HNC) cases detected by EBUS-TBNA consisted of nasopharyngeal carcinoma (n = 24), oropharyngeal carcinoma (n = 3), hypopharynx carcinoma (n = 6), laryngeal carcinoma (n = 6), and oral cavity carcinoma (n = 6). Cases with negative EBUS-TBNA results consisted of tuberculosis (n = 9), sarcoidosis (n = 3), anthracosis (n = 9), and reactive lymphadenitis (n = 9). Six false-negative cases were found among the 75 patients with suspected intrathoracic metastases. The diagnostic sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of the EBUS-TBNA procedure for metastatic HNC were 88.2, 100.0, 100.0, 80, and 92.0%, respectively. The diagnosis of HNC intrathoracic metastasis by EBUS-TBNA correlated with an adverse prognosis in terms of overall survival (OS) (P = .008). The log-rank univariate analysis and Cox regression multivariate analysis results indicated that the detection of metastatic HNC through EBUS-TBNA was a significant independent prognostic factor for patients with HNC who had received prior treatment. CONCLUSIONS Endobronchial ultrasound-guided transbronchial needle aspiration is a safe, effective, and minimally invasive procedure for assessing suspected intrathoracic metastasis in HNC patients after treatment. The intrathoracic metastasis detected by EBUS-TBNA has crucial prognostic significance in previously treated HNC patients.

Abstract
BACKGROUND Since their introduction, both linear and radial endobronchial ultrasound (EBUS) have become an integral component of the practice of Pulmonology and Thoracic Oncology. The quality of health care can be measured by comparing the performance of an individual or a health service with an ideal threshold or benchmark. The taskforce sought to evaluate quality indicators in EBUS bronchoscopy based on clinical relevance/importance and on the basis that observed significant variation in outcomes indicates potential for improvement in health care outcomes. METHODS A comprehensive literature review informed the composition of a comprehensive list of candidate quality indicators in EBUS. A multiple-round modified Delphi consensus process was subsequently performed with the aim of reaching consensus over a final list of quality indicators and performance targets for these indicators. Standard reporting items were developed, with a strong preference for items where evidence demonstrates a relationship with quality indicator outcomes. RESULTS Twelve quality Indicators are proposed, with performance targets supported by evidence from the literature. Standardized reporting items for both radial and linear EBUS are recommended, with evidence supporting their utility in assessing procedural outcomes presented. CONCLUSION This statement is intended to provide a framework for individual proceduralists to assess the quality of EBUS they provide their patients through the identification of clinically relevant, feasible quality measures. Emphasis is placed on outcome measures, with a preference for consistent terminology to allow communication and benchmarking between centres.

Abstract
Over the past decade, endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has become an indispensable tool in the diagnostic armamentarium of the pulmonologist. As the expertise with EBUS-TBNA has evolved and several innovations have occurred, the indications for its use have expanded. However, several aspects of EBUS-TBNA are still not standardized. Hence, evidence-based guidelines are needed to optimize the diagnostic yield and safety of EBUS-TBNA. For this purpose, a working group of experts from India was constituted. A detailed and systematic search was performed to extract relevant literature pertaining to various aspects of EBUS-TBNA. The modified GRADE system was used for evaluating the level of evidence and assigning the strength of recommendations. The final recommendations were framed with the consensus of the working group after several rounds of online discussions and a two-day in-person meeting. These guidelines provide evidence-based recommendations encompassing indications of EBUS-TBNA, pre-procedure evaluation, sedation and anesthesia, technical and procedural aspects, sample processing, EBUS-TBNA in special situations, and training for EBUS-TBNA.

Abstract
Since 2005, endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has emerged as a standard pulmonological tool. The procedure is safe and well tolerated by patients, with minimal morbidity and almost no mortality. A previous review on the technique was published in 2012. However, over the last ten years, a number of new studies have been published on "benign" (sarcoidosis, tuberculosis…) as well as "malignant" diseases (lung cancer, metastases of extra-thoracic cancers, search for mutations and specific oncogenic markers…). These developments have led to expanded indications for EBUS-TBNA, with which it is indispensable to be familiar, in terms of "staging" as well as "diagnosis". In view of optimizing lymph node sampling, several publications have described and discussed EBUS exploration by means of newly available tools (biopsy forceps, larger needles…), and proposed interpretation of the images thereby produced. Given the ongoing evolution of linear EBUS, it seemed indispensable that information on this marvelous tool be updated. This review is aimed at summarizing the novel elements we have found the most important.

Mondoni M, Sotgiu G. Optimizing the endoscopic diagnosis of mediastinal lymphadenopathy: a glimpse on cryobiopsy. BMC Pulm Med 2022; 22:355. [PMID: 36123592 PMCID: PMC9487110 DOI: 10.1186/s12890-022-02160-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Accepted: 09/14/2022] [Indexed: 12/02/2022] Open
Abstract
Etiological diagnosis of mediastinal lymphadenopathy represents a daily challenge. Endosonography (transesophageal and transbronchial ultrasound-guided needle aspiration) is the recommended technique in the first diagnostic work-up and in the mediastinal staging of lung cancer. Despite a good sensitivity, limited amount of collected tissue may hamper molecular assessment in advanced lung cancer and in the diagnosis of lymphoproliferative disorders, fibrotic sarcoidosis, and mycobacterial lymphadenitis. Cryobiopsy, a bronchoscopic technique based on cooling, crystallization, and subsequent collection of tissue, has been successfully employed in the diagnosis of interstitial lung diseases. Cryoprobes provide larger amount of tissue than conventional bronchoscopic sampling tools and might potentially prevent the need for invasive surgical procedures. New applications of the technique (e.g., bronchoscopic diagnosis of peripheral pulmonary lesions and mediastinal lymph nodes) have been recently described in few reports. In a recent issue of the Journal, Genova et al. described five patients who underwent endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) followed by ultrasound-guided transbronchial cryobiopsy of mediastinal lymphadenopathy for a suspected malignancy. The authors discussed about the potential added value of mediastinal cryobiopsy on a correct histopathological and molecular assessment in patients with malignancies. EBUS-cryobiopsy could be a promising technique in the diagnostic pathway of mediastinal lymphadenitis. However, cryobiopsy is now available only in few selected centres. The learning curve of the technique adapted to mediastinal ultrasound-guided sampling, the optimal sampling strategy, its true diagnostic accuracy in patients with malignant and benign diseases, as well as its safety, are still largely unclear. Mediastinal cryobiopsy could be complementary rather than alternative to conventional endosonography. Rapid on-site evaluation of EBUS-TBNA could guide subsequent sampling with cryoprobes in case of poor collection of biological material or in case of suspected lymphoproliferative disorders. Further studies should investigate its diagnostic yield, in comparison or in combination with conventional endosonography, in large cohorts of patients with malignant or benign mediastinal lymphadenopthies.

Abstract
INTRODUCTION :Cryobiopsy is a novel diagnostic technique for thoracic diseases which has been extensively investigated over the past 20 years. It was originally proposed for the diagnosis of endobronchial lesions and diffuse parenchymal lung disease due to limitations of conventional sampling techniques including small size and presence of artifacts. AREAS COVERED :We will review recent evidence related to the expanding use of cryobiopsy in thoracic diseases. To identify references, the MEDLINE database was searched from database inception until May 2022 for case series, cohort studies, randomized controlled trials, systematic reviews and meta-analyses related to cryobiopsy. EXPERT OPINION Cryobiopsy has expanding applications in the field of thoracic diseases. Evidence to support transbronchial cryobiopsy as an alternative to surgical lung biopsy is increasing and was recently endorsed as a conditional recommendation by the latest American Thoracic Society guideline update for Idiopathic Pulmonary Fibrosis. Developments in technology and technique, in particular the availability of a 1.1 mm flexible cryoprobe, have extended applications to pulmonary diseases, including diagnosis of interstitial lung diseases, peripheral pulmonary lesions, and lung transplant rejection.

Abstract
When evaluating mediastinal/hilar lymphadenopathy (LAD) or masses, guidelines recommend endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA) as an initial technique for tissue analysis and diagnosis. However, owing to the small sample size obtained by needle aspiration, its diagnostic yield (DY) is limited. EBUS transbronchial forceps biopsy (TBFB) used as a complimentary technique to EBUS-TBNA might allow for better histopathological evaluation, thus improving DY. In this retrospective bicentric study, we assessed the DY and safety of an EBUS-guided 1.5 mm mini-forceps biopsy combined with EBUS-TBNA for the diagnosis of mediastinal/hilar LAD or masses compared to EBUS-TBNA alone. In total, 105 patients were enrolled. The overall DY was 61.9% and 85.7% for TBNA alone and EBUS-TBNA combined with EBUS-TBFB, respectively (p < 0.001). While the combined approach was associated with a significantly higher DY for lung cancer diagnosis (97.1% vs. 76.5%, p = 0.016) and sarcoidosis (85.2% vs. 44.4%, p = 0.001), no significant differences in DY were calculated for subgroups with smaller sample sizes such as lymphoma. No major adverse events were observed. Using a 1.5 mm mini-forceps is a safe and feasible technique for biopsy of mediastinal or hilar LAD or masses with superior overall DY compared to EBUS-TBNA as a standalone technique.

Endobronchial ultrasound-guided transbronchial needle aspiration facilitating diagnosis of sarcoidosis in a breast cancer patient with multiple lymphadenopathy: a case report. J Med Case Rep 2022; 16:194. [PMID: 35585552 PMCID: PMC9118862 DOI: 10.1186/s13256-022-03428-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2021] [Accepted: 04/25/2022] [Indexed: 11/24/2022] Open
Abstract
Background Sarcoidosis is a benign systemic granulomatous disorder of unknown etiology. Cell-mediated immunity disorder is often found in sarcoidosis patients, and an association between malignant tumors and sarcoidosis has been suggested. Sarcoidosis and malignant disease can occur simultaneously or sequentially, leading to misdiagnosis and mistreatment. Sarcoidosis is diagnosed clinically, radiologically, and histologically. We report herein a case of sarcoidosis diagnosed by endobronchial ultrasound-guided transbronchial needle aspiration from the mediastinal lymph nodes of a breast cancer patient. Case presentation The patient was a 70-year-old Asian woman who presented with right breast tumor. A 20-mm movable mass was identified in the inferolateral quadrant of the right breast, and mammography revealed a spiculated mass with calcification. Ultrasonography revealed a mass with internal hypoechogenicity, and biopsy revealed estrogen receptor-positive, human epidermal growth factor receptor 2-positive invasive ductal carcinoma. Positron emission tomography/computed tomography showed multiple lymphadenopathy including mediastinal lymph nodes, with fluorodeoxyglucose accumulation in those nodes suggesting breast cancer metastases. Endobronchial ultrasound-guided transbronchial needle aspiration of a mediastinal lymph node revealed noncaseous epithelioid granuloma. Due to a history of uveitis and elevated soluble interleukin 2 receptor, lymphadenopathy due to sarcoidosis and stage IIA breast cancer were diagnosed. Right partial mastectomy and axillary lymph node dissection were performed after preoperative chemotherapy. No exacerbation of sarcoidosis symptoms has been observed during treatment. Conclusion We report a case of breast cancer in which sarcoidosis could be diagnosed based on endobronchial ultrasound-guided transbronchial needle aspiration, a history of uveitis, and elevated soluble interleukin 2 receptor despite fluorodeoxyglucose positron emission tomography/computed tomography suggesting multiple lymph node metastases. This report emphasizes the importance of differential diagnosis of lymph node involvements in cancer patients.

Abstract
Transbronchial mediastinal cryobiopsy is a novel sampling strategy that shows improved diagnostic utility for mediastinal lesions, particularly in rare tumors and benign disorders, as compared to standard endobronchial ultrasound-guided transbronchial needle aspiration. During this procedure, electrocautery incision is frequently needed to advance the cryoprobe through the airway into the mediastinal lesion, which however results in increased operative difficulty and prolonged procedural time. Here we present a case of mediastinal large B-cell lymphoma successfully diagnosed by transbronchial mediastinal cryobiopsy without cautery-induced airway incision.

Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is commonly used to evaluate mediastinal lymphadenopathy. Studies focusing on malignant lymphadenopathy have compared 21- and 22-gauge (21G and 22G, respectively) needles and have not identified an advantage of one needle size over the other in terms of diagnostic yield. RESEARCH QUESTION Does the 19-gauge (19G) EBUS needle offer greater diagnostic yield and sensitivity vs the 21G and 22G EBUS needles for a diagnosis of sarcoidosis, lymphoma, or mediastinal lymphadenopathy not yet diagnosed? STUDY DESIGN AND METHODS This study retrospectively examined records of 730 patients from the Stather Canadian Outcomes Registry for Chest Procedures (SCOPE) database who underwent EBUS-TBNA for a diagnosis of suspected sarcoidosis, lymphoma, or mediastinal lymphadenopathy not yet diagnosed. A propensity score analysis of two groups was performed. One group comprised patients undergoing EBUS-TBNA with a 19G needle, the other with a 21G or 22G needle. Cases for analysis were selected with a 1:2 ratio of 19G vs 21/22G using logistic regression and random matching with all eligible 19G cases included. RESULTS There were 137 patients (312 targets) in the 19G group and 274 patients (631 targets) in the 21/22G group in the propensity score analysis. The diagnostic yield was 107 of 137 (78.1%) in the 19G group vs 194 of 274 (70.8%) in the 21/22G group (difference, 7.3%; 95% CI, -1.9 to 15.6; P = .116). The sensitivity of EBUS-TBNA for sarcoidosis was 80 of 84 (95.2%) in the 19G group vs 150 of 156 (96.2%) in the 21/22G group (difference, 1.0%; 95% CI, -4.2 to 8.2; P = .71). In patients with a final diagnosis of lymphoma, EBUS was diagnostic in 10 of 13 (76.9%) in the 19G group vs 12 of 12 (100%) in the 21/22G group (difference, 23.1%; 95% CI, -5.4 to 50.3; P = .08). INTERPRETATION The study did not identify an advantage of the 19G EBUS needle over the 21/22G EBUS needles for diagnostic yield nor sensitivity for sarcoidosis or lymphoma.

Abstract
Background: Sarcoidosis is a multisystem disease characterized by noncaseating granulomatous inflammation that most commonly involves the lungs. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has become an invaluable tool in the assessment of patients with mediastinal and/or hilar lymphadenopathy. Objective: It has been hypothesized that use of the larger 19-gauge (G) needle with EBUS-TBNA improves diagnostic sensitivity in sarcoidosis. However, it is unclear whether the existing literature supports this supposition. Data Sources: A literature search of Embase and Medline was performed by two reviewers. Included articles were evaluated for bias using the QUADAS-2 tool. Data Extraction: For quantitative analysis, we performed a meta-analysis using a binary random-effects model to determine pooled sensitivity. Subgroup analysis was performed based on needle size, use of rapid on-site evaluation (ROSE), study design, and prevalence of sarcoidosis in study group. Synthesis: Sixty-five studies with a total of 4,242 patients were included in the meta-analysis. Overall pooled sensitivity for diagnosis of sarcoidosis was 83.99% (95% confidence interval [CI], 81.22-86.53) among all studies. The 19G subgroup had a significantly higher sensitivity (93.73%; 95% CI, 89.72-97.74%; I2 = 0.00%; P < 0.01) compared with the 21G subgroup (84.61%; 95% CI, 78.80-90.42%; I2 = 69.83%), 22G subgroup (84.07%; 95% CI, 80.90-87.24%; I2 = 85.21%) or unspecified 21G/22G subgroup (78.85%; 95% CI, 70.81-86.90%; I2 = 84.47%). There were no significant differences with use of ROSE or prevalence of sarcoidosis or by study design. Conclusions: The use of 19G needles during EBUS-TBNA had the highest diagnostic sensitivity based on available studies. Further randomized controlled trials using 19G needles should be considered in patients with suspected sarcoidosis.

Abstract
Fine-needle cytology (FNC) is a useful diagnostic tool in the first line evaluation of lymphadenopathy of unknown aetiology. Nevertheless, considering the large number of conditions presenting as lymphadenopathy, lymph node cytology represents a challenging scenario. Recently, an expert panel published the proposal of the Sydney system for performing classification and reporting of lymph node cytopathology; the aim of the present study was to evaluate the applicability of this system. Thus, 300 lymph node FNCs performed over 1 year were reviewed and categorized according to the Sydney system classification. Overall, n = 20 cases (6.7%) were categorized as L1-inadequate/non-diagnostic; n = 104 (34.7%) as benign (L2); n = 25 (8.3%) as atypical (L3); n = 13 (4.3%) as suspicious (L4), and n = 138 (46%) as malignant (L5). FNC diagnoses were correlated with histopathologic and clinical follow-up to assess the diagnostic accuracy and the risk of malignancy (ROM) for each diagnostic category. Statistical analysis showed the following results: sensitivity 98.47%, specificity 95.33%, positive predictive value 96.27%, negative predictive value 98.08%, and accuracy 97.06%. The ROM was 50% for the category L1, 1.92% for L2, 58.3% for L3, and 100% for L4 and L5. In conclusion, FNC coupled with ancillary techniques ensures satisfactory diagnostic accuracy and the implementation of the Sydney system may improve the practice of cytopathologists.

Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a widely used, safe, and accurate technique for obtaining pathological specimens to be used in the diagnosis of diseases involving lung hilar and mediastinal lymph node (LN) enlargement. However, application of the suction technique during EBUS-TBNA remains controversial. In addition, the effectiveness of the slow-pull capillary technique for the diagnosis of pancreatic masses was recently reported. The aim of this study was to compare the diagnostic accuracy of EBUS-TBNA using these two techniques. METHODS The accuracy, sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), and availability of tissue cores of the suction and slow-pull capillary techniques were studied retrospectively in patients who underwent EBUS-TBNA for the diagnosis of diseases involving lung hilar and mediastinal LN enlargement. RESULTS A total of 97 patients with hilar and mediastinal LN enlargement underwent EBUS-TBNA; 30 patients underwent the suction technique, 56 patients underwent the slow-pull capillary technique, 5 patients underwent both techniques, and 6 patients had failed operations. The accuracy, sensitivity, specificity, NPV, PPV, and the number of tissue cores obtained with the suction and slow-pull capillary techniques were 66.67% versus 85.71% (p = 0.039), 43.75% versus 85.42% (p < 0.001), 92.86% versus 87.5% (p > 0.05), 59.09% versus 50% (p > 0.05), 87.5% versus 97.62% (p > 0.05), and 19 versus 50 (p = 0.004), respectively. In both univariate and multivariate analyses, the acquisition of tissue core was significantly associated with the diagnostic accuracy of EBUS-TBNA. Moreover, the slow-pull capillary technique was significantly associated with the acquisition of tissue core in EBUS-TBNA. There were no significant differences between the two groups in the blood contamination of samples. CONCLUSIONS Use of the slow-pull capillary technique in EBUS-TBNA can significantly increase the accuracy related to the diagnosis of diseases involving hilar and mediastinal LN enlargement by improving the acquisition of tissue core.

Abstract
OBJECTIVES The practice of cytopathology has evolved over the past decade with a growing need for doing more with less tissue. Changes in clinical practice guidelines and evolving needs in tissue acquisition for diagnosis and treatment have affected various areas of cytopathology in different ways. In this study, we evaluated the changing trends in cytopathological practice at our institution over the past decade. METHODS We performed a retrospective review of our institutional database for cytopathology cases from calendar years 2009 (n = 28038) and 2019 (n = 31386) to evaluate the changing trends in practice. RESULTS The overall number of exfoliative cases decreased 10% over the past decade, primarily due to a 64% decrease in gynaecological Pap testing. However, the volume of serous body cavity and cerebrospinal fluids increased 125% and 44%, respectively. The overall volume of fine needle aspiration (FNA) cases increased 38% from 2009 to 2019. The number of FNA cases increased across most body sites, driven primarily by a 180% increase in endobronchial ultrasound-guided transbronchial needle aspiration cases. In contrast, breast FNA volume decreased 43%. Ancillary studies increased substantially over the past decade, including immunostains (476%) and molecular testing (250%). CONCLUSIONS The trends in our cytopathological practice showed an increased volume of cases, especially in non-gynaecological specimens. As expected, the number of FNA cases used for immunostains and molecular testing increased substantially, indicating an upward trend in ancillary studies in cytopathological practice.

Abstract
Convex probe endobronchial ultrasound (CP-EBUS) has been widely used in the lymph node staging and restaging of lung tumors and the diagnosis of mediastinal diseases. Recent years have seen continuous progress in this technology. For diagnosis, elastography technology can preliminarily distinguish between benign and malignant lesions, so that reduce the number of punctures. CP-EBUS can also be used as an endoscopic ultrasound (EUS) to guide needle aspirations of liver lesions, retroperitoneal lymph nodes and left adrenal gland (LAG) lesions sometimes. Some advances help diagnosing more accurately and effectively, such as the intranodal forceps biopsy (IFB), the new type of 22G needle, the rapid on-site evaluation (ROSE) and the cancer gene methylation, etc. In addition, special advances are being made in diagnosis using artificial intelligence (AI). For treatment, CP-EBUS has yielded novel research results when applied to transbronchial needle injection (TBNI) and radioactive seed implantation in clinical cases, and blocking of the cardiac plexus in animal studies. The next-generation CP-EBUS is also ready for use in the clinic and the technology will be improving continuously. Through this review, we hope to educate clinicians on the latest uses of CP-EBUS and open up further research ideas for readers interested in this technology.

Abstract
BACKGROUND In the last decade, the advent of thoracic endosonography has revolutionised the field of diagnostic bronchoscopy. METHODS We conducted a single-centre prospective study in "Sotiria" Chest diseases hospital between January 2016 and December 2019. The study aimed to evaluate the efficacy and diagnostic value of combined EBUS/EUS-b in comparison with EBUS-TBNA and EUS-b FNA in different intrathoracic diseases. RESULTS A total of 266 patients were enrolled (70.7% males, 85.7% smokers, mean age ± SD: 62.8 ± 11.8). Diagnosis and staging of suspected lung cancer (LC) were the main indications for EBUS/EUS-b in 56.7% of patients, followed by lymphadenopathy of unknown origin in 27%, lymphadenopathy in previous malignancy in 10.9%, and staging of proven LC in 5.3%. EUS-b FNA alone or combined with EBUS-TBNA was performed in 14.7% of patients. A total of 512 lymph nodes was sampled (481 through EBUS-TBNA and 31 through EUS-b FNA). EBUS/EUS-b led to a definitive diagnosis in 68.4% of the patients. Most cases (50.4%) were malignancies, while 18% represented benign diseases (83.3% sarcoidosis). Sensitivity of combined EBUS/EUS-b was higher in comparison with sensitivity of both procedures alone (100% vs 89.4% vs 88.9%). Accordingly, the overall sensitivity of EBUS/EUS-b for the detection of malignancy and sarcoidosis was 93% and 95.2%, respectively. No severe complications were observed. CONCLUSION Thoracic endosonography is an efficient, safe, minimally invasive tool yielding high sensitivity and diagnostic accuracy in patients with suspected malignancy and mediastinal lymphadenopathy. Experienced pulmonologists in EBUS-TBNA should more routinely perform EUS-b FNA to avoid unnecessary surgical interventions.

Abstract
Endobronchial ultrasound-guided transbronchial biopsy has emerged as an excellent tool in diagnosing lung cancer. However, its use to diagnose lymphoma has been questioned, since the gold standard for diagnosing lymphomas is an excisional biopsy of involved lymph nodes. However, the procedure is sometimes risky or difficult. Recent studies have been showing great results using endobronchial ultrasound-guided transbronchial needle aspiration when accompanied by immunohistochemistry and cytology. Here, we present a case of Hodgkin's lymphoma patient that was accurately diagnosed using endobronchial ultrasound-guided transbronchial needle aspiration.

Abstract
BACKGROUND Interventional pulmonology is a rapidly evolving subspecialty of pulmonary medicine that offers advanced consultative and procedural services to patients with airway diseases, pleural diseases, as well as in the diagnosis and management of patients with thoracic malignancy. AREAS OF UNCERTAINTY The institution of lung cancer screening modalities as well as the search of additional minimally invasive diagnostic and treatment modalities for lung cancer and other chronic lung diseases has led to an increased focus on the field of interventional pulmonology. Rapid advancements in the field over the last 2 decades has led to development of various new minimally invasive bronchoscopic approaches and techniques for patients with cancer as well as for patients with chronic lung diseases. DATA SOURCES A review of literature was performed using PubMed database to identify all articles published up till October 2020 relevant to the field of interventional pulmonology and bronchoscopy. The reference list of each article was searched to look for additional articles, and all relevant articles were included in the article. THERAPEUTIC ADVANCES Newer technologies are now available such navigation platforms to diagnose and possibly treat peripheral pulmonary nodules, endobronchial ultrasound in diagnosis of mediastinal and hilar adenopathy as well as cryobiopsy in the diagnosis of diffuse lung diseases. In addition, flexible and rigid bronchoscopy continues to provide new and expanding ability to manage patients with benign and malignant central airway obstruction. Interventions are also available for diseases such as asthma, chronic bronchitis, chronic obstructive pulmonary disease, and emphysema that were traditionally treated with medical management alone. CONCLUSIONS With continued high quality research and an increasing body of evidence, interventional bronchoscopy has enormous potential to provide both safe and effective options for patients with a variety of lung diseases.

Abstract
BACKGROUND Endobronchial ultrasound (EBUS) guided intranodal forceps biopsy (IFB) is considered complimentary to EBUS-TBNA for patients with intrathoracic lymphadenopathy when either additional tissue is requested for comprehensive molecular testing, or for suspected lymphoma and sarcoidosis. This is a systematic review and meta-analysis to investigate the diagnostic yield and complications of combined EBUS-IFB and EBUS-TBNA compared to EBUS-TBNA alone. METHODS We performed a systematic search of MEDLINE, Embase, and Google Scholar for studies evaluating the use of EBUS-IFB for diagnosis of intrathoracic adenopathy, assessing the quality of each study using the QUADAS-2 tool. Using inverse-variance weighting, we performed a meta-analysis of diagnostic yield estimations. We also reviewed the complications related to the procedure. RESULTS Six observational studies with 443 patients undergoing 467 biopsies were included in the final analysis. Meta-analysis yielded a pooled overall diagnostic yield of 67% (312/467) for EBUS-TBNA and 92% (428/467) for EBUS-TBNA + EBUS-IFB, with an inverse variance - weighted OR of 5.87 (95% CI, 3081 to 9.04, p<0.00001) and an I 2of 15%. The overall complications included pnuemomediastinum (1%), bleeding (0.8%) and respiratory failure (0.6%). The funnel plot analysis illustrated no major publication bias. Subgroup analysis showed increased diagnostic yield for lymphoma (86% vs 30%, p=0.03) and sarcoidosis (93% vs 58%, p<0.00001). CONCLUSIONS The addition of EBUS-IFB to EBUS-TBNA improves the overall diagnostic yield of sampling intrathoracic adenopathy when compared to EBUS-TBNA alone. The complication rates of the combined approach are higher than with EBUS-TBNA, but are reportedly lower than with transbronchial or surgical biopsies.

Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and transesophageal bronchoscopic ultrasound-guided fine-needle aspiration (EUS-B-FNA) are established modalities for evaluation of mediastinal/hilar lymphadenopathy in adults. Limited literature is available on the utility of these modalities in the pediatric population. Herein, we perform a systematic review and meta-analysis on the yield and safety of EBUS-TBNA and EUS-B-FNA in children. METHODS We performed a systematic search of the PubMed and EMBASE databases to extract the studies reporting the utilization of EBUS-TBNA/EUS-B-FNA in children (<18 years of age). The pooled diagnostic yield and sampling adequacy (proportions with 95% confidence intervals [CIs]) were calculated using meta-analysis of proportions using the random effects model. Details of any procedure-related complications were noted. RESULTS The search yielded 12 relevant studies (5 case series and 7 case reports on EBUS-TBNA/EUS-B-FNA, 173 patients). Data from five case series (164 patients) were summarized for the calculation of the sampling adequacy and diagnostic yield. Safety outcomes were extracted from all publications. The pooled sampling adequacy and combined diagnostic yield of EBUS TBNA/EUS-B-FNA were 98% (95% CI, 92%-100%) and 61% (95% CI, 43%-77%), respectively. A procedure-related major complication was reported in one patient (1/173, a major complication rate of 0.6%), and minor complications occurred in six patients (6/173, a minor complication rate of 3.5%). CONCLUSIONS EBUS-TBNA and EUS-B-FNA are safe modalities for evaluation of mediastinal lymphadenopathy in the pediatric population. EBUS-TBNA/EUS-B-FNA may be considered as the first-line diagnostic modalities for this indication, as they have a good diagnostic yield and can avoid the need for invasive diagnostic procedures.

Abstract
Bronchoscopy has evolved over the past few decades and has been used by respiratory physicians to diagnose various airway and lung diseases. With the popularization of medical check-ups and growing interest in health, early diagnosis of lung diseases is essential. With the development of endobronchial ultrasound, ultrathin bronchoscopy, and electromagnetic navigational bronchoscopy, bronchoscopy has been able to widen its scope in diagnosing pulmonary diseases. In this review, we have described the brief history, role, and complications of bronchoscopy used in diagnosing pulmonary lesions, from simple flexible bronchoscopy to bronchoscopy combined with several up-to-date technologies.

Abstract
Fine needle aspiration (FNA) cytology is a sparsely used diagnostic method in the evaluation of mediastinal sarcomas in most medical centers worldwide with most literature citations regarding this category of malignancies consisting of small series and individual case reports. Most of these published studies highlight vascular sarcomas such as epithelioid hemangioendothelioma, and angiosarcoma, various subtypes of liposarcoma including well-differentiated liposarcoma, myxoid liposarcoma, and pleomorphic liposarcoma, malignant peripheral nerve sheath tumor, and sarcomas of uncertain differentiation, primary synovial sarcoma and the Ewing sarcoma family of tumors. This paucity of cytopathology reports regarding mediastinal sarcomas is in marked contrast to the almost daily application of endobronchial ultrasound (EBUS)-guided FNA biopsy for sampling mediastinal lymph nodes and mediastinal masses for primary and metastatic carcinomas which, of course, are considerably more common that any type of sarcoma in this location. EBUS, endoscopic ultrasound-guided (EUS) needle biopsy, and percutaneous image-guided biopsy using either core needle, fine-needle, or both can serve a potentially useful role for diagnostic sampling of mediastinal sarcomas, be they primary or metastatic. This review catalogues much of the published data regarding FNA cytopathology and its application to mediastinal sarcomas. An attempt is made to primarily highlight case series rather than individual case reports; however, due to the paucity of these, case reports are cited and discussed where appropriate.

Abstract
INTRODUCTION Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) represents a minimally invasive approach in the evaluation of mediastinal/hilar lymphadenopathy. Diagnostic performance of EBUS-TBNA in lymphoma using standard 22-gauge (22G) needle is limited by sample volumes that are often inadequate for histopathological assessment. OBJECTIVES To evaluate the diagnostic utility of 19-gauge (19G) EBUS-TBNA needle in the evaluation of suspected lymphoma. METHODS We prospectively collected clinical and procedural information for patients undergoing EBUS-TBNA with 19G needle at Royal Melbourne Hospital for investigation of mediastinal/hilar lymphadenopathy, where lymphoma was considered in the differential diagnosis. All consecutive patients between June 15, 2016 and July 10, 2019 were included. If definitive diagnosis was not achieved on EBUS-TBNA, final diagnosis was determined through subsequent investigation or a minimum of 6 months radiologic surveillance. RESULTS Thirty-nine patients underwent EBUS-TBNA using 19G needle for evaluation of suspected lymphoma. Thirteen patients had a prior diagnosis of lymphoma (33%). Lymphoma was ultimately diagnosed in 23 patients (59%). Of these, 10 had a prior diagnosis of lymphoma (43%). 19G EBUS-TBNA demonstrated lymphoma in 19 patients, with a sensitivity of 83% (95% CI 66-93) for detection of lymphoma. Four patients required surgical biopsy to definitively characterise lymphoma subtype. Therefore, sensitivity of 19G EBUS-TBNA for definitive diagnosis of lymphoma was 65% (95% CI 45-81). In patients with a prior diagnosis of lymphoma, sensitivity for definitive diagnosis of lymphoma was 80% (95% CI 48-95). CONCLUSION Diagnostic performance of 19G EBUS-TBNA appears similar to standard 22G needle in detection and definitive diagnosis of lymphoma. Further invasive testing remains necessary following non-diagnostic EBUS-TBNA procedures.

Abstract
INTRODUCTION Adequate sampling by endobronchial ultrasound (EBUS)-transbronchial needle aspiration to meet the demands of precision medicine or histologic evaluation is challenging. There is increasing demand for core biopsy specimens with advances in therapy. Franseen enodoscopic ultrasound needles have shown promising results in gastroenterology application for obtaining core biopsies and same design has recently been extended for pulmonary use. We evaluated Franseen needles with EBUS to assess its utility, safety and ability to provide core biopsy specimens. MATERIALS AND METHODS Retrospective analysis of our database at the University of Utah of patients undergoing EBUS with a Franseen needle was performed to ascertain the performance characteristics of this needle in the first 100 patients after its implementation. Medical records were also reviewed to identify any immediate procedure-related complications. RESULTS One hundred seventy locations were sampled in 100 patients. A total of 152 lymph nodes and 18 masses were sampled. Core biopsies, as per pathology report, were seen in 87% of patients. A clinically concordant pathological diagnosis was established in 97% of patients. Diagnostic yield for granulomatous lymphadenopathy was 95.6% (22 of 23). No patient-related adverse events were noted. CONCLUSION The Franseen needle evaluated in this study can safely procure core tissue samples during EBUS bronchoscopy that are adequate for histopathological diagnosis in benign and malignant lesions. Its ability to provide adequate tissue in patients with granulomatous inflammation is encouraging.

Endobronchial ultrasound-guided transbronchial needle aspirate for diagnosis of anaplastic large cell lymphoma of unusual presentation: A case report. Respir Med Case Rep 2020; 29:101027. [PMID: 32140403 PMCID: PMC7047010 DOI: 10.1016/j.rmcr.2020.101027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2019] [Revised: 02/13/2020] [Accepted: 02/20/2020] [Indexed: 11/16/2022] Open
Abstract
Anaplastic large cell lymphoma (ALCL) is a rare type of non-Hodgkin lymphoma (NHL) originated from mature post thymic T cells. They represent 1-3% of NHL. Different subtypes have been described: Anaplastic lymphoma kinase (ALK)-negative ALCL, ALK-positive ALCL and breast implant-associated ALCL. ALK-positive ALCL affects mainly the young and has better prognosis. We present a case report of an adult woman with AKL-positive ALCL, diagnosed by endobronchial ultrasound-guided transbronchial needle aspirate (EBUS-TBNA). A 59-year-old women with no history of breast implants, was admitted for a four-month low back pain. Initially, the patient was treated for a spondyloarthropathy, but due to persistence of the symptoms, a lumbosacral MRI was performed, showing changes in morphology and signal intensity in the vertebral body of L3, along with edema and a paravertebral collection that affected the left psoas muscle, suggesting granulomatous spondylodiscitis. Chest CT-scan showed mild left pleural effusion, subcarinal and right hiliar adenomegalies. An EBUS-TBNA with ROSE (rapid on-site evaluation) was performed showing positive findings for malignancy, suggestive of hematolymphoid neoplasia. Pathology analysis showed an AKL-positive ALCL. Additionally, a biopsy of paravertebral tissue biopsy was obtained, which was consistent with the nodal sample. Chemotherapy was initiated with the CHOP protocol: cyclophosphamide, hydroxydaunorubicin, vincristine sulfate and prednisone. EBUS-TBNA is a minimally invasive and safe technique for obtaining mediastinal samples. Collaboration with a cytopathologist trained to perform ROSE improves the diagnostic performance.

Abstract
Mediastinal biopsy is essential for the clinical diagnosis of mediastinal disease. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a well-established approach for obtaining diagnostic samples from mediastinal masses or enlarged lymph nodes which is proven to be minimally invasive and effective. However, the insufficiency of intact samples acquired might restrict the diagnostic efficacy of EBUS-TBNA for mediastinal lesions such as rare malignancy and granulomatous disorder. We here present an EBUS-guided approach for the cryobiopsy of mediastinal diseases that is capable of providing larger amounts of intact tissue with few observed complications.
