Abstract
BACKGROUND The convex-probe endobronchial ultrasound (CP-EBUS) bronchoscope is widely used in clinical practice. Despite improvements, the existing CP-EBUS remains limited in accessing areas beyond the mediastinum due to its large distal end diameter, long rigid tip segment, and oblique viewing angle. To address this limitation, Olympus Medical Systems Corporation developed the thin CP-EBUS (TCP-EBUS). This study aimed to compare the accessibility and puncturing ability of TCP-EBUS with existing CP-EBUS in cadaveric models. METHODS Ten bronchoscopists conducted this study using 2 cadaveric models. The accessibility of TCP-EBUS was evaluated based on the number of bronchial generations that could be reached. To assess the puncturing ability of TCP-EBUS, needle punctures were performed on previously created simulated lesions in the segmental or subsegmental bronchial area, and puncture success rates were calculated. RESULTS TCP-EBUS demonstrated greater accessibility than CP-EBUS in all segmental bronchi, with statistically significant differences observed in several bronchi (P<0.05). Puncture success rates for simulated lesions using TCP-EBUS were also significantly higher than those using CP-EBUS in both the segmental (85.0% vs. 60.0%, P<0.001) and subsegmental bronchial areas (84.4% vs. 38.9%, P<0.001). In a questionnaire survey, TCP-EBUS was perceived as significantly superior in terms of usability (P<0.05). CONCLUSION TCP-EBUS has significantly improved both accessibility and puncture performance, providing an advantage over CP-EBUS in segmental and subsegmental bronchial areas. TCP-EBUS has the potential to expand the indications for endobronchial ultrasound-guided transbronchial needle aspiration.

Nakajima T. An update on the role of endobronchial ultrasound-guided transbronchial needle aspiration in lung cancer management. Expert Rev Respir Med 2025; 19:423-434. [PMID: 40159145 DOI: 10.1080/17476348.2025.2486349] [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: 01/21/2025] [Accepted: 03/26/2025] [Indexed: 04/02/2025]
Abstract
INTRODUCTION Accurate diagnosis and staging are essential for optimizing lung cancer management. The 9th edition of the TNM classification emphasizes distinguishing between single-station and multi-station N2 disease, highlighting the necessity of comprehensive mediastinal node assessment for clinical staging. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive modality used for nodal staging and diagnosis of lung cancer, offering a diagnostic yield comparable to that of mediastinoscopy when performed by experts. Additionally, EBUS-TBNA facilitates essential ancillary testing, including next-generation sequencing (NGS)-based biomarker panels and PD-L1 immunohistochemistry, which are critical for evaluating the suitability of targeted therapies and immune checkpoint inhibitors. Notably, advancements in perioperative management, such as neoadjuvant and adjuvant therapies with immunotherapy and targeted agents, have improved the outcomes of locally advanced diseases. EBUS-TBNA helps identify patients with early-stage lung cancer who are candidates for perioperative therapy. AREAS COVERED This review discusses lung cancer diagnosis, nodal staging, the 9th TNM classification, biomarker testing, PD-L1 immunohistochemistry, and precision medicine. EXPERT OPINION Lung cancer management requires pathological diagnosis, including histological subtyping, accurate nodal staging of the hilum and mediastinum, and NGS-based biomarker and PD-L1 testing. EBUS-TBNA achieves all three in a single session, making it indispensable in modern lung cancer care.

Abstract
Background/Objectives: Recent advances in the treatment of non-small cell lung cancer (NSCLC) have shifted from conventional chemotherapy to targeted therapies aimed at specific genetic mutations, particularly in the adenocarcinoma subtype. These therapies have improved overall survival and quality of life. However, some patients still face barriers to accessing these treatments due to challenges in diagnosing advanced-stage NSCLC. Limited tumor cellularity in small biopsies and cytological samples hinders the ability to perform further molecular analyses. Additionally, the increasing number of genetic alterations requiring testing complicates the diagnostic process. To overcome this challenge, we propose combining endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) with next-generation sequencing (NGS) and immunohistochemistry for PD-L1. Methods: A total of 120 EBUS-TBNA samples were consecutively collected during the first year of integrating NGS at a reference hospital in Castilla y León, Spain. Depending on the histology and patient characteristics, a total of 67 NGS analyses and 116 PD-L1 determinations were performed. Results: The cytological sample obtained in these cases successfully achieved the triple objective proposed by the NCCN for lung cancer (diagnosis, staging, and molecular analysis in a single procedure) in 97% of instances. Conclusions: Our study highlights the effectiveness of EBUS-TBNA as a comprehensive, cost-effective, and safe diagnostic tool for NSCLC, successfully achieving the triple objective of diagnosis, staging, and molecular analysis in 97% of cases. The procedure consistently provided high-quality samples for NGS and PD-L1 testing, with minimal complications, reinforcing its value as a reliable approach for optimizing personalized treatment strategies.

Abstract
Endobronchial ultrasound (EBUS)-guided mediastinal cryobiopsy and intranodal forceps biopsy are newer modalities for sampling mediastinal lymph nodes. The data regarding the diagnostic yield of both modalities is scarce. Patients were recruited retrospectively from our existing database. Patients who had undergone both an EBUS-guided mediastinal cryobiopsy and an intranodal forceps biopsy were enrolled in the study. The final diagnosis was made with a clinical-pathological-radiological assessment and clinical-radiological follow-up after 1 month. A total of 34 patients were enrolled in the study who had undergone both EBUS-guided mediastinal cryobiopsy and intranodal forceps biopsy and had complete data available, including 1-month follow-up data. The sample adequacy rate of EBUS-transbronchial needle aspiration (EBUS-TBNA), EBUS-TBNA with mediastinal cryobiopsy, and EBUS-TBNA with intranodal forceps biopsy was 94.11%, 97.05%, and 94.11%, respectively (p=0.56). The diagnostic yield achieved in EBUS-TBNA, EBUS-TBNA with mediastinal cryobiopsy, and EBUS-TBNA with intranodal forceps biopsy was 73.52%, 82.35%, and 79.41%, respectively (p=0.38). No major complications were seen in any patient. To conclude, adding EBUS-guided mediastinal cryobiopsy and intranodal forceps biopsy to EBUS-TBNA may not be superior to routine EBUS-TBNA.

Diagnostic value and safety of contact laser-assisted endobronchial ultrasound-guided tunnel drilling biopsy in mediastinal and hilar lymphadenopathy: a retrospective study. Front Med (Lausanne) 2025; 12:1520690. [PMID: 39950125 PMCID: PMC11821499 DOI: 10.3389/fmed.2025.1520690] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2024] [Accepted: 01/14/2025] [Indexed: 02/16/2025] Open
Abstract
Introduction Mediastinal and hilar lymphadenopathies are primarily diagnosed pathologically. Contact laser-assisted endobronchial ultrasound-guided tunnel drilling biopsy (EBUS-TDB), which uses a laser as a tunneling and incision tool, may yield more satisfactory specimens than conventional endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), thereby improving the diagnostic yield. This study aims to evaluate the diagnostic value and safety of contact laser-assisted EBUS-TDB compared to EBUS-TBNA in the assessment of mediastinal and hilar lymph nodes. Methods This retrospective study included patients who presented to our hospital between October 2022 and April 2024 with mediastinal or hilar lymph nodes of short diameter ≥ 1 cm on computed tomography (CT) or abnormally increased lymph node metabolism on positron emission tomography (PET)-CT. All patients underwent both EBUS-TBNA and EBUS-TDB procedures successively. Results Overall, 278 patients were included in the study, and 244 cases were confirmed. The diagnostic rates (p-values) for EBUS-TDB and EBUS-TBNA in pulmonary and extrapulmonary malignancies, lymphoma, sarcoidosis, and lymph node tuberculosis were 96.6% vs. 76.3% (0.043), 100% vs. 67.7% (-), 88.9% vs. 31.1% (0.555), and 69.2% vs. 30.8% (0.049), respectively. No serious adverse events occurred during or after either procedure. Conclusion Contact laser-assisted EBUS-TBNB demonstrates superior diagnostic performance compared to EBUS-TBNA for the evaluation of mediastinal or hilar lymph nodes, making it an alternative to EBUS-TBNA for enhanced diagnostic precision.

Abstract
PURPOSE OF REVIEW Biopsy tools have been essential in improving the diagnostic accuracy of bronchoscopic procedures. Of these tools, cryobiopsy has emerged as a promising technique for diagnosing thoracic diseases. This review summarizes the existing data comparing cryobiopsies to other mechanical biopsy methods for sampling endobronchial, parenchymal, and mediastinal targets. RECENT FINDINGS Initially adopted for managing airway stenoses, the use of cryoprobes has expanded to diagnosing endobronchial lesions, parenchymal opacities, and mediastinal lymph node pathologies. Studies have demonstrated that cryobiopsy offers a higher diagnostic yield than forceps biopsy alone. By leveraging the Joule-Thomson effect to freeze and collect larger tissue samples compared to traditional methods, cryobiopsy improves diagnostic accuracy and helps in better characterizing the nature of the lesions. While the risk of complications, such as pneumothorax and hemorrhage are comparable to, or higher than traditional biopsy methods, cryobiopsy's enhanced diagnostic capabilities make it a valuable tool in the assessment of pulmonary disease. SUMMARY Compared with other mechanical biopsy techniques, cryoprobe biopsies significantly enhance the diagnostic yield for endobronchial lesions, interstitial lung disease, pulmonary nodules, and mediastinal lymph nodes.

Abstract
Aims/Background Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is the standard method for sampling mediastinal/hilar lymph node disease. However, the smaller samples obtained via needle aspiration have a lower diagnostic rate for benign compared to malignant diseases. The low diagnostic rates have been reported to be improved through using endobronchial ultrasound-guided intranodal forceps biopsy (EBUS-IFB), but the implementation of IFB presents technical challenges, as described with variable results in certain studies. The main objective of this study was to investigate the diagnostic value and safety of EBUS-IFB for mediastinal/hilar lymph node disease. Methods A retrospective analysis was conducted on 150 patients with mediastinal/hilar lymph node disease at Tianjin Medical University General Hospital. EBUS-TBNA was performed using a rigid bronchoscope on the same lymph node of each patient under general anesthesia, with rapid on-site evaluation (ROSE) conducted to determine the presence of pathological tissue. Following this, a tunnel was established, and a 1.5 mm biopsy forceps was employed for EBUS-IFB. Subsequently, diagnostic rates and safety of the methods used were determined. Results EBUS-IFB + EBUS-TBNA (the combined strategy) exhibited the highest diagnostic rates, with the addition of bronchial mucosa biopsy/transbronchial lung biopsy/neoplasm biopsy contributing to a successful diagnostic rate of 97.2% (139/143). The combined strategy (90.2%) and EBUS-IFB alone (88.1%) contributed to successful diagnosis for all diseases, with rates significantly higher than that of EBUS-TBNA (60.1%) (p < 0.001). The diagnostic rates for malignant disease detected with the combined strategy (97.4%) and EBUS-IFB alone (93.6%) were significantly higher than that with EBUS-TBNA alone (71.8%) (p < 0.001). Both the diagnostic rates for sarcoidosis detected with the combined strategy and EBUS-IFB alone were 87.8%, which was significantly higher than that with EBUS-TBNA alone (46.9%) (p < 0.001). The procedures implemented did not engender major complications. Conclusion Routine EBUS-TBNA followed by ROSE to acquire pathological tissue, followed by tunnel formation and EBUS-IFB, can enhance the overall diagnostic rate for mediastinal/hilar lymph node lesions. This approach is particularly valuable for diagnosing malignant diseases and sarcoidosis. EBUS-IFB serves as a safe and feasible complement to EBUS-TBNA, despite the fact that the procedure was extended in duration.

Abstract
BACKGROUND Limited data exist on the reliability, efficacy and safety of ultrasound-guided transbronchial cryobiopsy for suspicious mediastinal and hilar lesions. This study shares findings from implementing this method and compares the results with those of the standard endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). METHODS Patients undergoing diagnostic bronchoscopy for mediastinal or hilar lesions in four Swiss centres were included. The study aims to assess the diagnostic yield and safety of EBUS-guided cryobiopsy compared with EBUS-TBNA. Tunnelling to the target lesion was performed using an electric needle knife (70.8%), a 19 G- (12.4%) or a 22 G needle (16.8%). Cryobiopsies were obtained with a freezing time of 4-7 s (18.2% with a 1.7 mm probe) or 6-10 s (81.8% with a 1.1 mm probe). RESULTS Altogether, 137 patients were enrolled with a median follow-up of 89 days. The overall diagnostic yield was 56.2% for EBUS-TBNA and 91.2% for cryobiopsies (p<0.001). Cryobiopsies increased the diagnostic yield for benign disorders (+28.5%), uncommon tumours (+5.9%) and other metastatic cancer (+0.6%), but not for lung cancer (+0%). For lung cancer (n=27), immunohistochemistry was obtainable in 40.7% of EBUS-TBNA (median of 3 probes [IQR 3 to 3]), significantly lower than cryobiopsy's 88.9% yield (median of 4 probes [IQR 3 to 5]) (p<0.001). Adverse events were found in 23.4% of participants; 10.2% had mild to moderate bleeding, 0.7% had pneumonia, and 0.7% (one) of patients had pneumothorax following pneumomediastinum. No deaths or mediastinum infections were observed. CONCLUSION Cryobiopsy of mediastinal and hilar lesions improves the diagnostic yield compared with EBUS-TBNA while maintaining a favourable safety profile.

Abstract
In this prospective study, we evaluated the diagnostic yield and safety of two endobronchial ultrasound (EBUS) biopsy techniques - mediastinal cryobiopsy (EBUS-MCB) and Franseen tip needle biopsy (EBUS-ANB) - in patients with undiagnosed mediastinal lymphadenopathy. The study included 30 patients who underwent both EBUS-MCB and EBUS-ANB, with four biopsies taken from each patient using both methods. The results demonstrated that EBUS-MCB provided a higher diagnostic yield (96.4%) compared to EBUS-ANB (73.3%). Specimens from EBUS-MCB showed fewer artifacts and a higher density of granulomas and were adequate for ancillary studies in all cases. The most common complication observed was minor bleeding, which was more common with EBUS-MCB (36.6% versus 13.3%, p=0.04). This study demonstrates that EBUS-guided cryobiopsy has a higher diagnostic yield when compared to EBUS-guided Franseen tip needle biopsy and that both biopsy techniques have an acceptable safety profile. Larger studies comparing these two techniques are necessary to confirm the findings of the current study.

Abstract
BACKGROUND Various types of needles are available to perform endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). A relatively new needle for EBUS-TBNA, the Acquire Fine Needle Biopsy (FNB) device, has recently become available. METHODS Consecutive subjects with lymphadenopathy >1 cm undergoing EBUS-TBNA were randomized to the Acquire 22-G EBUS-FNB needle and the standard 22-G EBUS-TBNA needle groups. RESULTS A total of 86 subjects were randomized (43 in each group). The diagnostic yield of EBUS-TBNA was similar between the two groups: (36/43) 83.7% in the 22-G EBUS-FNB group and (34/43) 79.1% in the standard 22-G EBUS group (p = 0.58). The sampling adequacy, stations sampled, number of stations sampled, number of needle passes, and mean duration of the procedure between the two groups were also similar. Visible tissue clot core was obtained in a significantly greater proportion of subjects in the 22-G EBUS-FNB group (93.0% vs 46.5%, p < 0.001). Visibly bloody samples were more frequent in the 22-G EBUS-FNB group (74.4% vs 51.2%, p = 0.03). There was no difference in the complication rates between the two groups (p = 0.15). CONCLUSION We did not observe a difference in the diagnostic yield of the Acquire 22-G EBUS-FNB needle compared with the standard 22-G EBUS needle.

Abstract
Mediastinal lymphadenopathy has a broad differential diagnosis which includes lymphoma. The current preferred biopsy technique for mediastinal lymph nodes is transbronchial needle aspiration which has mixed results in terms of sensitivity, specificity and diagnostic yields; there are also limitations with subtyping lymphomas with needle aspiration alone which can be a barrier to determine management strategies. Invasive mediastinal lymph node sampling such was with mediastinoscopy provides higher yields and preserved lymph node architecture for both diagnosis and subtyping of lymphoma but carries a higher risk of morbidity and complications. Novel techniques that may increase the diagnostic yield of bronchoscopy in the diagnosis of lymphoma are core biopsy needles, intranodal forcep biopsy, and intranodal cryobiopsy. The evidence is limited due to a relatively small number of cases, so further research is needed to standardize best practices for the bronchoscopic diagnosis of lymphoma. Pleural effusions in lymphoma can be present in up to 30 % of cases with the majority being non-Hodgkins's lymphoma. The presence of exudative effusion in the setting of an existing or prior diagnosis of lymphoma should raise clinical suspicions. Other less common subtypes of lymphoma presenting as primary pleural effusions are explored as well.

Abstract
INTRODUCTION Pulmonary endoscopy occupies a central role in Interventional Pulmonology and is frequently the mainstay of diagnosis of respiratory disease, in particular lung malignancy. Older techniques such as rigid bronchoscopy maintain an important role in central airway obstruction. Renewed interest in the peripheral pulmonary nodule is driving major advances in technologies to increase the diagnostic accuracy and advance new potential endoscopic therapeutic options. AREAS COVERED This paper describes the role of pulmonary endoscopy, in particular ultrasound in the diagnosis and staging of lung malignancy. We will explore the recent expansion of ultrasound to include endoscopic ultrasound - bronchoscopy (EUS-B) and combined ultrasound (CUS) techniques. We will discuss in detail the advances in the workup of the peripheral pulmonary nodule.We performed a non-systematic, narrative review of the literature to summarize the evidence regarding the indications, diagnostic yield, and safety of current bronchoscopic sampling techniques. EXPERT OPINION EBUS/EUS-B has revolutionized the diagnosis and staging of thoracic malignancy resulting in more accurate assessment of the mediastinum compared to mediastinoscopy alone, thus reducing the rate of futile thoracotomies. Although major advances in the assessment of the peripheral pulmonary nodule have been made, the role of endoscopy in this area requires further clarification and investigation.

Abstract
This narrative review examines the existing literature on minimally invasive image-guided sampling techniques of mediastinal lesions gathered from international databases (Medline, PubMed, Scopus, and Google Scholar). Original studies, systematic reviews with meta-analyses, randomized controlled trials, and case reports published between January 2009 and November 2023 were included. Four authors independently conducted the search to minimize bias, removed duplicates, and selected and evaluated the studies. The review focuses on the recent advancements in mediastinal sampling techniques, including EBUS-TBNA, EUS-FNA and FNB, IFB, and nodal cryobiopsy. The review highlights the advantages of an integrated approach using these techniques for diagnosing and staging mediastinal diseases, which, when used competently, significantly increase diagnostic yield and accuracy.

Abstract
INTRODUCTION Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is the standard approach for lung cancer staging. However, its diagnostic utility for other mediastinal diseases might be hampered by the limited tissue retrieved. Recent evidence suggests the novel sampling strategies of forceps biopsy and cryobiopsy as auxiliary techniques to EBUS-TBNA, considering their capacity for larger diagnostic samples. METHODS This study determined the added value of forceps biopsy and cryobiopsy for the diagnosis of mediastinal diseases. Consecutive patients with mediastinal lesions of 1 cm or more in the short axis were enrolled. Following completion of needle aspiration, three forceps biopsies and one cryobiopsy were performed in a randomised pattern. Primary endpoints included diagnostic yield defined as the percentage of patients for whom mediastinal biopsy led to a definite diagnosis, and procedure-related complications. RESULTS In total, 155 patients were recruited and randomly assigned. Supplementing EBUS-TBNA with either forceps biopsy or cryobiopsy increased diagnostic yield, with no significant difference between EBUS-TBNA plus forceps biopsy and EBUS-TBNA plus cryobiopsy (85.7 % versus 91.6 %, P = 0.106). Yet, samples obtained by additional cryobiopsies were more qualified for lung cancer molecular testing than those from forceps biopsies (100.0 % versus 89.5 %, P = 0.036). When compared directly, the overall diagnostic yield of cryobiopsy was superior to forceps biopsy (85.7 % versus 70.8 %, P = 0.001). Cryobiopsies produced greater samples in shorter procedural time than forceps biopsies. Two (1.3 %) cases of postprocedural pneumothorax were detected. CONCLUSIONS Transbronchial mediastinal cryobiopsy might be a promising complementary tool to supplement traditional needle biopsy for increased diagnostic yield and tissue harvesting.

The Effect of Hounsfield Unit Value on the Differentiation of Malignant/Benign Mediastinal Lymphadenopathy and Masses Diagnosed by Endobronchial Ultrasonography. Cancer Manag Res 2024; 16:1013-1020.

Abstract
Aim In cases where standardized maximum uptake (SUVmax) values in positron emission tomography (PET-CT) were not sufficient to differentiate mediastinal lymphadenopathy and masses from malignant or benign, the contribution of Hounsfield unit (HU) values in thorax computed tomography to the diagnosis was evaluated. Material Method The study was conducted by evaluating the data of 182 patients between 2019 and 2023. HU values on non-contrast thorax computed tomography and PET-CT SUVmax values of biopsied masses and lymph nodes were compared with histopathological diagnoses. Results Patients, 58 females (31.9%) and 124 males (68.1%), who underwent EBUS were included in the study. Biopsies were taken from 233 stations (199 lymph nodes, 34 masses) from 182 patients. A total of 135 of the biopsies taken from 233 stations were histopathologically malignant and 98 were benign. While PET-CT SUVmax values of cases with benign histopathology were 4.5 ± 3.5, it was 7.6 ± 4.2 in patients with malignant pathology (p<0.05). The HU value on non-contrast thorax tomography in patients with benign histopathology was 43.1 ± 15.7, and in patients with malignant histopathology it was 40.5 ± 13.7 (p>0.05). When HU was compared according to lung cancer type, it was found to be significantly higher in non-small cell lung cancer (p=0.035). A weak (r=0.182) positive and significant relationship (p<0.01) was found between PET-CT values and HU values in thorax computed tomography. Conclusion While positron emission tomography maintains its importance in the differentiation of mediastinal lymphadenopathy and masses from malignant to non-malignant, it was concluded that HU values in computed tomography are not sufficient to distinguish malignant/non-malignant.

Abstract
Schwannomas are classified as neurogenic tumors and are the most frequent nerve sheath tumors in the paravertebral mediastinum. Recently, the addition of endobronchial ultrasound-guided intranodal forceps biopsy (EBUS-IFB) using standard-sized biopsy forceps (SBFs) to endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for metastatic lymph nodes in lung cancer patients reportedly improved the quality and quantity of the obtained specimens without significant complications. However, reports on the usefulness of this technique for benign diseases remain scarce. Here we report a case of schwannoma in the middle mediastinum, which was diagnosed by EBUS-IFB using SBFs, despite inadequate specimens obtained via EBUS-TBNA. An 80-year-old woman presented with dyspnea and a 5-cm sized middle mediastinal tumor. EBUS-TBNA and EBUS-IFB using SBFs were performed for histological diagnosis. No complications were associated with the bronchoscopy procedure, and schwannoma was solely diagnosed using the EBUS-IFB specimens. EBUS-IFB using SBFs is potentially useful for diagnosing benign diseases, including schwannomas, which are often difficult to diagnose with EBUS-TBNA.

Abstract
Benign and malignant mediastinal lesions are not infrequently encountered in clinical practice. Mediastinoscopy has long been considered the gold standard in evaluating mediastinal pathology. Since its introduction into clinical practice, endobronchial-ultrasonography-guided transbronchial fine needle aspiration (EBUS-TBNA) has replaced mediastinoscopy as the initial procedure of choice to evaluate mediastinal lesions and to stage lung cancer. Its diagnostic yield in benign mediastinal lesions and less common malignancies, however, has remained limited. This has led different proceduralists to investigate additional procedures to improve the diagnostic yield of EBUS-TBNA. In recent years, different published reports concluded that the addition of EBUS-guided intranodal forceps biopsy (IFB) and transbronchial cryobiopsy (TBCB) to EBUS-TBNA increases the diagnostic yield especially in benign mediastinal lesions and uncommon mediastinal malignancies. The purpose of this review is to describe how EBUS-IFB and EBUS-TBCB are performed, to compare their diagnostic yields, and to discuss their limitations and their potential complications. In addition, the review will conclude with a proposed algorithm on how to incorporate EBUS-IFB and EBUS-TBCB into clinical practice.

Abstract
BACKGROUND AND OBJECTIVE Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a diagnostic procedure with adequate performance; however, its ability to provide specimens of sufficient quality and quantity for treatment decision-making in advanced-stage lung cancer may be limited, primarily due to blood contamination. The use of a 0.96-mm miniforceps biopsy (MFB) permits true histological sampling, but the resulting small specimens are unsuitable for the intended applications. Therefore, we introduced a 1.9-mm standard-sized forceps biopsy (SFB) and compared its utility to that of MFB. METHODS We prospectively enrolled patients from three institutions who presented with hilar/mediastinal lymphadenopathy and suspected advanced-stage lung cancer, or those who were already diagnosed but required additional tissue specimens for biomarker analysis. Each patient underwent MFB followed by SFB three or four times through the tract created by TBNA using a 22-gauge needle on the same lymph node (LN). Two pathologists assessed the quality and size of each specimen using a virtual slide system, and diagnostic performance was compared between the MFB and SFB groups. RESULTS Among the 60 enrolled patients, 70.0% were diagnosed with adenocarcinoma. The most frequently targeted sites were the lower paratracheal LNs, followed by the interlobar LNs. The diagnostic yields of TBNA, MFB and SFB were 91.7%, 93.3% and 96.7%, respectively. The sampling rate of high-quality specimens was significantly higher in the SFB group. Moreover, the mean specimen size for SFB was three times larger than for MFB. CONCLUSION SFB is useful for obtaining sufficient qualitative and quantitative specimens.

[PMID: 38114815 DOI: 10.1007/s10396-023-01391-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: 07/30/2023] [Accepted: 10/19/2023] [Indexed: 12/21/2023]
Abstract
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has emerged as a revolutionary diagnostic tool for lung diseases, including lung cancer, sarcoidosis, and lymphoproliferative diseases. This minimally invasive procedure offers a superior diagnostic yield while ensuring maximum patient safety when compared to traditional invasive techniques such as mediastinoscopy and thoracoscopy. By enabling real-time imaging and sampling of mediastinal and hilar lymph nodes and masses directly from the bronchoscope, EBUS-TBNA has redefined the precision of diagnostic bronchoscopy. This comprehensive review explores the origins, development, and current status of EBUS-TBNA, highlighting its successes and identifying potential areas for improvement. Technological advancements have continuously enhanced the reliability and efficacy of EBUS-TBNA over time. The mechanisms underlying the superior diagnostic yield of EBUS-TBNA are thoroughly discussed, further solidifying its position as the gold standard for lung cancer staging and diagnosis. Furthermore, this review delves into the crucial role of EBUS-TBNA in lung cancer diagnosis, supported by studies comparing its accuracy, safety, and cost-effectiveness to other diagnostic tools. Looking ahead, ongoing research aims to expand the applications of EBUS-TBNA and improve its diagnostic performance. Notable advancements in needle design and sampling techniques hold promise for further enhancing its efficacy. Maximizing its potential through comprehensive training and continuous technological developments will enable broader clinical applications, ultimately leading to improved patient outcomes. As EBUS-TBNA continues to evolve, its diagnostic impact is expected to increase, solidifying its position as an indispensable tool in the diagnosis and management of lung diseases.

Abstract
Sarcoidosis is a multisystem inflammatory disorder with unclear etiology and can often pose a diagnostic challenge. A tissue diagnosis is often necessary to illustrate the non-caseating granulomas on histopathology. This review aims to synthesize current evidence related to tissue diagnosis of sarcoidosis using various bronchoscopic techniques. We start by discussing standard bronchoscopic techniques which have remained the cornerstone of diagnostic workup such as bronchoalveolar lavage (BAL), endobronchial biopsy (EBB), conventional transbronchial needle aspiration (cTBNA) and transbronchial lung biopsy (TBLB) followed by newer modalities that incorporate real-time image guidance using endobronchial and endoscopic ultrasound. Although BAL, EBB, and TBLB have been employed as a diagnostic tool for several decades, their sensitivity and diagnostic yield is inferior to ultrasound-based endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). More recently, convincing evidence has also emerged to support the diagnostic accuracy and tissue yield of transbronchial lung cryobiopsy which will also be discussed in this review. These advances in bronchoscopic equipment and techniques over the last 2 decades have made it possible to obtain tissue samples using minimally invasive techniques thus avoiding invasive open lung biopsy and the risks that inherently follow. Up-to-date knowledge of these modalities is imperative for ensuring evidence-based medicine and improving patient-centric outcomes.

Endobronchial Ultrasound-guided Mediastinal Lymph Nodal Cryobiopsy in Patients With Nondiagnostic/Inadequate Rapid On-site Evaluation: A New Step in the Diagnostic Algorithm. J Bronchology Interv Pulmonol 2024; 31:2-12.

Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is considered the investigation of choice for sampling mediastinal nodes. A major drawback of EBUS-TBNA is its lower diagnostic yield for lymphoma and benign diseases. EBUS-guided mediastinal cryobiopsy (EBUS-MCB) is a novel technique that provides larger nodal biopsy samples, with an acceptable safety profile. In this study, we aimed to evaluate the diagnostic yield of EBUS-MCB in patients with an inconclusive rapid on-site evaluation (ROSE). METHODS This is a prospective study of patients who underwent EBUS-TBNA for undiagnosed mediastinal lymphadenopathy. Patients in whom ROSE did not yield a diagnosis (nondiagnostic ROSE) or ROSE revealed scanty atypical cells (inadequate ROSE) were subjected to EBUS-MCB. The diagnostic yield, adequacy, and complications of EBUS-MCB were analyzed. RESULTS Of the 196 patients undergoing EBUS-TBNA, 46 patients underwent EBUS-MCB. Thirty-two cases underwent EBUS-MCB for a nondiagnostic ROSE. EBUS-MCB confirmed the diagnosis in 19/32 (59.3%) cases. The additive diagnostic yield of EBUS-MCB over EBUS-TBNA was 43.7% (14/32 cases). In all 14 cases where EBUS-MCB was performed for an inadequate ROSE, the material obtained by EBUS-MCB was adequate for ancillary studies. The most common complication observed was a minor bleed in 13 cases. CONCLUSION EBUS-MCB has a diagnostic yield of 59.3% when performed in cases with a nondiagnostic EBUS-ROSE. The tissue obtained by EBUS-MCB is adequate for ancillary studies. We propose EBUS-MCB as an additional diagnostic step in cases with an inconclusive ROSE while performing EBUS-TBNA. Larger studies are, however, needed before EBUS-MCB can be incorporated in the diagnostic algorithm for the evaluation of mediastinal lesions.

Abstract
BACKGROUND Patients with mediastinal lymph node enlargement (MLNE) are diagnosed depending on lymph node biopsy. Whereas, how to obtain larger tissue masses from mediastinal lymph nodes and improve the diagnostic yield of the disease remains to be investigated. OBJECTIVES Aiming to assess the diagnostic value of endobronchial ultrasound-guided intranodal forceps biopsy via transbronchial laser photoablation (EBUS-IFB-TLP) in patients with MLNE. DESIGN A prospective, self-controlled study. METHODS This study was conducted on 67 MLNE patients requiring a lymph node biopsy for diagnosis at the Henan Provincial People's Hospital and the Fuwai Central China Cardiovascular Hospital in China, from January 2020 to December 2022. Each patient underwent endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA group) and EBUS-IFB-TLP (EBUS-IFB-TLP group) on the same mediastinal lymph node for biopsies. The operation time, diagnostic efficiency, and complication rates of the two biopsy methods were compared. RESULTS The number of diagnosed patients in the EBUS-IFB-TLP and the EBUS-TBNA groups was 65 (97.0%) and 57 (85.1%), respectively (p = 0.021). In the EBUS-IFB-TLP group, 28 cases (96.6%) were diagnosed with lung cancer and were classified into different epithelial types. In the EBUS-TBNA group, there were 27 cases (93.1%) diagnosed with lung cancer, of which 26 (89.7%) were classified into different epithelial types. There were 37 (97.4%) and 30 (78.9%) non-lung cancer patients diagnosed in the EBUS-IFB-TLP and EBUS-TBNA groups, respectively (p = 0.039), while 27 cases (96.4%) of sarcoidosis in the EBUS-IFB-TLP group and 20 cases (71.4%) of sarcoidosis in the EBUS-TBNA group were diagnosed (p = 0.016). The percentages of intraoperative mild to moderate bleeding complications were 23.9% (16/67) and 14.9% (10/67) in the EBUS-IFB-TLP and in the EBUS-TBNA groups, respectively (p = 0.109). CONCLUSION This study demonstrated that EBUS-IFB-TLP could be a feasible and effective method in the diagnosis of patients with MLNE, presenting an analogous safety profile compared with EBUS-TBNA. Further studies are needed to verify the diagnostic performance of EBUS-IFB-TLP for MLNE.

Abstract
PURPOSE OF REVIEW Appropriate staging is of utmost importance in nonsmall cell lung cancer (NSCLC), as the pathologic stage dictates both overall prognosis and appropriate therapeutic pathways. This article seeks to review the current recommendations for mediastinal staging of NSCLC and available modalities to achieve this. Landmark publications pertaining to recent advancements in NSCLC treatments are also highlighted and the role of specific bronchoscopic modalities for tissue acquisition are reviewed. RECENT FINDINGS Recent advancements in the treatment of NSCLC have made accurate mediastinal staging more important than ever. Guidelines and recommendations outlining patients that warrant invasive mediastinal staging are available and a systematic approach should be utilized when sampling is performed. Ensuring the adequacy of tissue for the growing number of molecular biomarkers that must be tested has been the focus of many recent studies. SUMMARY Appropriate mediastinal staging is crucial for the management of patients with NSCLC as is obtaining adequate tissue for diagnostic and therapeutic purposes. EBUS-TBNA is sufficient for the diagnosis of nonsmall cell and small cell lung carcinomas, but EBUS-guided intranodal forceps and cryobiopsy may provide more optimal specimen for patients with benign disease, such as sarcoidosis, or in cases of lymphoma. Further studies are necessary to better delineate the role of these techniques in the diagnosis and staging of mediastinal diseases before they become the primary diagnostic modalities.

Abstract
BACKGROUND It is essential to collect a sufficient amount of tumor tissue for successful next-generation sequencing (NGS) analysis. In this study, we investigated the clinical risk factors for avoiding re-biopsy for NGS analysis (re-genome biopsy) in cases where a sufficient amount of tumor tissue could not be collected by bronchoscopy. METHODS We investigated the association between clinical factors and the risk of re-genome biopsy in patients who underwent transbronchial biopsy (TBB) or endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and required re-genome biopsy in cases enrolled in LC-SCRUM Asia, a prospective nationwide genome screening project in Japan. We also examined whether the frequency of re-genome biopsy decreased between the first and second halves of the enrolment period. RESULTS Of the 572 eligible patients, 236 underwent TBB, and 134 underwent EBUS-TBNA. Twenty-four TBBs required re-genome biopsy, and multivariate analysis showed that the risk of re-genome biopsy was significantly increased in lesions where the tumor lesion was centrally located. In these cases, EBUS-TBNA should be utilized even if the lesion is a pulmonary lesion. However, it should be noted that even with EBUS-TBNA, lung field lesions are at a higher risk of re-canalization than mediastinal lymph node lesions. It was also found that even when tumor cells were detected in rapid on-site evaluation, a sufficient amount of tumor tissue was not always collected. CONCLUSIONS For centrally located pulmonary mass lesions, EBUS-TBNA, rather than TBB, can be used to obtain tumor tissues that can be analyzed by NGS.

Abstract
(1) Background: endobronchial ultrasound-guided mediastinal transbronchial cryo-node biopsy, previously assisted by fine-needle aspiration, is a novel technique of particular interest in the field of lung cancer diagnosis and is of great utility for extrathoracic tumor metastases, lymphomas, and granulomatous diseases. An integrated histological and molecular diagnosis of small samples implies additional difficulty for the pathologist. Additionally, emerging tumor biomarkers create the need to search for new approaches to better manage the tissue sample; (2) Methods: An analytical observational study of 32 mediastinal node cryobiopsies is carried out in 27 patients (n = 27). Statistical analysis using the t-student and Wilcoxon signed-rank tests for paired data is performed with SPSS 26 and R Statistical software. The significance level is established at p < 0.05; (3) Results: cryobiopsies were valid for diagnosis in 25 of 27 patients, with a maximum average size of 3.5 ± 0.7 mm. A total of 18 samples (66.67%) were positive for malignancy and 9 (33.33%) were benign. The tumor percentage measured in all neoplastic samples was greater than 30%. The average DNA and RNA extracted in nine non-small cell lung cancer cases was 97.2 ± 22.4 ng/µL and 26.6 ± 4.9 ng/µL, respectively; (4) Conclusions: the sample size obtained from an endobronchial ultrasound-guided mediastinal transbronchial cryo-node biopsy facilitates the morphological and histo-architectural assessment of inflammatory and neoplastic pathology. It optimizes molecular tests in the latter due to more tumor cells, DNA, and RNA.

Abstract
Endobronchial Ultrasound (EBUS) has been widely used to stage lung tumors and to diagnose mediastinal diseases. In the last decade, this procedure has evolved in several technical aspects, with new tools available to optimize tissue sampling and to increase its diagnostic yield, like elastography, different types of needles and, most recently, miniforceps and cryobiopsy. Accordingly, the indications for the use of the EBUS scope into the airways to perform the Endobronchial Ultrasound-TransBronchial Needle Aspiration (EBUS-TBNA) has also extended beyond the endobronchial and thoracic boundaries to sample lesions from the liver, left adrenal gland and retroperitoneal lymph nodes via the gastroesophageal tract, performing the Endoscopic UltraSound with Bronchoscope-guided Fine Needle Aspiration (EUS-B-FNA). In this review, we summarize and critically discuss the main indication for the use of the EBUS scope, even the more uncommon, to underline its utility and versatility in clinical practice.

Abstract
The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice.Accurate staging of the mediastinal lymph nodes in resectable non-small-cell lung cancer (NSCLC) is critically important to determine the overall stage of the tumor and guide subsequent management. The staging process typically begins with positron emission tomography (PET) or computed tomography imaging; however, imaging alone is inadequate, and tissue acquisition is required for confirmation of nodal disease. Mediastinoscopy was long considered the gold standard for staging of mediastinal lymph nodes, but, recently, endobronchial ultrasound-guided (EBUS) fine-needle aspiration (FNA) has become the standard of care. EBUS-FNA, in combination with supplementary technologies, such as intranodal forceps biopsy and esophageal ultrasonography, has a high sensitivity and specificity for the diagnosis of nodal metastases. EBUS-FNA is also capable of assessing N1 disease and obtaining adequate tissue for tumor genomic analysis to help guide treatment. In the case of negative findings on EBUS, a confirmatory video mediastinoscopy is still recommended by the European Society of Thoracic Surgeons guidelines. However, whether confirmatory mediastinoscopy is necessary is a matter of debate, and it is not commonly performed in North America. To address this question, Bousema and colleagues performed a randomized noninferiority trial to determine rates of unforeseen nodal metastases after EBUS alone versus EBUS with confirmatory mediastinoscopy in patients with resectable NSCLC. The authors concluded that EBUS alone is noninferior to EBUS with confirmatory mediastinoscopy. These findings affirm our current practice to forgo confirmatory mediastinoscopy after negative findings on EBUS.

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.

Front Med (Lausanne) 2023; 10:1150751.

Abstract
Diagnosing pulmonary sarcoidosis raises challenges due to both the absence of a specific diagnostic criterion and the varied presentations capable of mimicking many other conditions. The aim of this review is to help non-sarcoidosis experts establish optimal differential-diagnosis strategies tailored to each situation. Alternative granulomatous diseases that must be ruled out include infections (notably tuberculosis, nontuberculous mycobacterial infections, and histoplasmosis), chronic beryllium disease, hypersensitivity pneumonitis, granulomatous talcosis, drug-induced granulomatosis (notably due to TNF-a antagonists, immune checkpoint inhibitors, targeted therapies, and interferons), immune deficiencies, genetic disorders (Blau syndrome), Crohn's disease, granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis, and malignancy-associated granulomatosis. Ruling out lymphoproliferative disorders may also be very challenging before obtaining typical biopsy specimen. The first step is an assessment of epidemiological factors, notably the incidence of sarcoidosis and of alternative diagnoses; exposure to risk factors (e.g., infectious, occupational, and environmental agents); and exposure to drugs taken for therapeutic or recreational purposes. The clinical history, physical examination and, above all, chest computed tomography indicate which differential diagnoses are most likely, thereby guiding the choice of subsequent investigations (e.g., microbiological investigations, lymphocyte proliferation tests with metals, autoantibody assays, and genetic tests). The goal is to rule out all diagnoses other than sarcoidosis that are consistent with the clinical situation. Chest computed tomography findings, from common to rare and from typical to atypical, are described for sarcoidosis and the alternatives. The pathology of granulomas and associated lesions is discussed and diagnostically helpful stains specified. In some patients, the definite diagnosis may require the continuous gathering of information during follow-up. Diseases that often closely mimic sarcoidosis include chronic beryllium disease and drug-induced granulomatosis. Tuberculosis rarely resembles sarcoidosis but is a leading differential diagnosis in regions of high tuberculosis endemicity.

Transbronchial needle aspiration combined with cryobiopsy in the diagnosis of mediastinal diseases: a multicentre, open-label, randomised trial. THE LANCET. RESPIRATORY MEDICINE 2023; 11:256-264. [PMID: 36279880 DOI: 10.1016/s2213-2600(22)00392-7] [Citation(s) in RCA: 48] [Impact Index Per Article: 24.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/28/2022] [Revised: 09/09/2022] [Accepted: 09/15/2022] [Indexed: 11/07/2022]
Abstract
BACKGROUND Transbronchial mediastinal cryobiopsy is a novel sampling technique for mediastinal disease. Despite the possibility of lung cancer misdiagnosis, the improved diagnostic yield of this approach for non-lung-cancer lesions compared with standard endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) highlights its diagnostic potential as a complementary technique to conventional biopsy. We aimed to evaluate the safety profile and added value of the combined use of transbronchial mediastinal cryobiopsy and standard EBUS-TBNA for the diagnosis of mediastinal diseases. METHODS We conducted an open-label, randomised trial at three hospital sites in Europe and Asia. Eligible patients were aged 15 years or older, with at least one mediastinal lesion of 1 cm or longer in the short axis that required diagnostic bronchoscopy. Participants were randomly assigned (1:1) using a block randomisation scheme generated by a computer (block size of four participants based on a random table from an independent statistician) to the combined use of EBUS-TBNA and transbronchial mediastinal cryobiopsy (combined group) or EBUS-TBNA alone (control group). Because of the nature of the intervention, neither participants nor investigators were masked to group assignment. The coprimary outcomes were differences in procedure-related complications and diagnostic yield (defined as the proportion of participants for whom mediastinal biopsy led to a definitive diagnosis), assessed in the full analysis set, including all the patients who met the eligibility criteria and had a biopsy. A fully paired, intraindividual diagnostic analysis in participants who had both needle aspiration and mediastinal cryobiopsy was conducted, in addition to interindividual comparisons. This trial is now complete and is registered with ClinicalTrials.gov, NCT04572984. FINDINGS Between Oct 12, 2020, and Sept 9, 2021, 297 consecutive patients were assessed for eligibility and 271 were enrolled and randomly assigned to the combined group (n=136) or the control group (n=135). The addition of cryobiopsy to standard sampling significantly increased the overall diagnostic yield for mediastinal lesions, as shown by both interindividual (126 [93%] of 136 participants in the combined group vs 109 [81%] of 135 in the control group; risk ratio [RR] 1·15 [95% CI 1·04-1·26]; p=0·0039) and intraindividual (126 [94%] of 134 vs 110 [82%] of 134; RR 1·15 [95% CI 1·05-1·25]; p=0·0026) analyses. In subgroup analyses in the intraindividual population, diagnostic yields were similar for mediastinal metastasis (68 [99%] of 69 participants in the combined group vs 68 [99%] of 69 in the control group; RR 1·00 [95% CI 0·96-1·04]; p=1·00), whereas the combined approach was more sensitive than standard needle aspiration in benign disorders (45 [94%] of 48 vs 32 [67%] of 48; RR 1·41 [95% CI 1·14-1·74]; p=0·0009). The combined approach also resulted in an improved suitability of tissue samples for molecular and immunological analyses of non-small-cell lung cancer. The incidence of adverse events related to the biopsy procedure did not differ between trial groups, as grade 3-4 airway bleeding occurred in three (2%) patients in the combined group and two (1%) in the control group (RR 0·67 [95% CI 0·11-3·96]; p=1·00). There were no severe complications causing death or disability. INTERPRETATION The addition of mediastinal cryobiopsy to standard EBUS-TBNA resulted in a significant improvement in diagnostic yield for mediastinal lesions, with a good safety profile. These data suggest that this combined approach is a valid first-line diagnostic tool for mediastinal diseases. FUNDING National Natural Science Foundation of China.

Abstract
Thoracic SMARCA4-deficient undifferentiated tumors (SMARCA4-UT) have a poor prognosis and are often diagnosed at an inoperable advanced stage. Herein, we report a case of SMARCA4-UT diagnosed by endobronchial ultrasound-guided transbronchial cryobiopsy (EBUS-cryo). The patient was a 42-year-old man with a history of smoking. Chest computed tomography revealed a right upper lobe nodule and an enlarged #11s lymph node. Core tissues could not be obtained by EBUS-guided transbronchial needle aspiration (EBUS-TBNA) for diagnosis and mediastinal staging; hence, EBUS-guided intranodal forceps biopsy (EBUS-IFB) was performed. However, a detailed diagnosis beyond poorly differentiated carcinoma could not be obtained. Subsequent EBUS-cryo provided sufficient specimens for immunohistochemical and molecular evaluation and SMARCA4-UT was definitively diagnosed. Thus, EBUS-cryo could be of additional diagnostic value for uncommon tumors, such as SMARCA4-UT, conjointly with EBUS-IFB as well as EBUS-TBNA.

Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is valuable for diagnosing pulmonary sarcoidosis. We aimed to evaluate the diagnostic yield of EBUS-TBNA and cytology in sarcoidosis during the first 9 years at our institution. METHODS Patients who underwent EBUS-TBNA for suspected sarcoidosis between January 2011 and November 2019 were identified retrospectively. EBUS-TBNA was performed with rapid on-site cytological evaluation of the samples. The final diagnosis was based on the pathology and/or cytology results, radiologic features, and clinical follow-up findings. The yield rate was analyzed annually. RESULTS Eighty patients underwent 83 EBUS-TBNA procedures for suspected sarcoidosis. In total, 136 lymph nodes were sampled. The mean number of lymph node stations sampled was 2.0 ± 0.6; the mean number of needle passes per lymph node was 3.5 ± 0.8. Sixty-five patients were diagnosed with sarcoidosis, with a total of 68 procedures. Nonnecrotizing granulomatous inflammation was detected in the EBUS-TBNA samples from 49/68 procedures (yield rate: 72.1%). Of 19 patients with sarcoidosis who did not obtain a pathological diagnosis with EBUS-TBNA, epithelioid cells and/or multinuclear giant cells suggestive of granulomatous inflammation were detected in five. The sensitivity, specificity, positive predictive value, and negative predictive value (NPV) for pathological diagnosis of sarcoidosis using EBUS-TBNA were 72.1%, 100%, 100%, and 24.0%, respectively. On using cytology, the sensitivity and NPV increased to 79.4% and 26.3%, respectively. The yield rate did not increase until 2016. CONCLUSION EBUS-TBNA is useful for diagnosing sarcoidosis. Cytology resulted in an additional yield rate of 7.3%, which improved as the number of cases increased.

Abstract
Cryobiopsy is advantageous for collecting larger specimens with minimum crushing compared to forceps biopsy and transbronchial needle aspiration (TBNA), but it has not been widely used for mediastinal tumors. In this report, a leiomyoma of the thoracic esophagus was diagnosed with endobronchial ultrasound-guided transbronchial mediastinal cryobiopsy (EBUS-cryo). An asymptomatic 49-year-old woman had a 2.6-cm sized submucosal tumor (SMT) of the esophagus adjacent to the trachea and left main bronchus. EBUS-TBNA and EBUS-guided intranodal forceps biopsy were performed, followed by EBUS-cryo. The biopsy forceps could not be inserted into the tumor, but the cryoprobe was smoothly inserted. EBUS-TBNA could not obtain enough spindle-shaped tumor cells for immunohistochemical staining, but EBUS-cryo provided sufficient specimens for diagnosing the leiomyoma. Adding EBUS-cryo to EBUS-TBNA has recently been reported to achieve high diagnostic yields for lymphomas, uncommon tumors, and benign diseases. EBUS-cryo seems a valid diagnostic option for esophageal SMTs that are difficult to diagnose with needles and forceps.

Abstract
INTRODUCTION Endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) is a standard procedure in cases of enlarged mediastinal lymph nodes. Recently, new tools were developed aiming to improve the diagnostic yield. A novel crown-cut needle is considered to obtain tissue cores which can be beneficial for the evaluation by the pathologist. This study aimed to compare the novel 22G crown-cut needle with a conventional 22G needle with EBUS guidance in the diagnosis of sarcoidosis. METHODS We designed a single-center prospective randomized clinical trial between March 2020 and January 2021 with 30 patients with mediastinal lymphadenopathy and suspected sarcoidosis. RESULTS 24 patients (mean age 49.5 vs 54.1, mean FVC 73.7% vs 86.7%, mean DLCO 72.4% vs 72.5% for crown-cut needle vs conventional needle, respectively) were diagnosed with sarcoidosis. In the remaining six patients, sarcoidosis was reasonably excluded. The diagnostic yield for sarcoidosis was 77% with the crown-cut needle vs. 82% with the conventional needle (p > 0.05). In patients with histopathologic hallmarks typical of sarcoidosis (n = 19), the crown-cut needle was superior in detecting granulomas (8.3 vs 3.8 per cytoblock, p < 0.05) and histiocytes (502 vs 186 per cytoblock, p < 0.05). Four of seven bronchoscopists experienced difficulties passing through the bronchial wall with the crown-cut needle and one episode of bleeding occurred in this group which made interventions necessary. CONCLUSIONS Despite equivalence in diagnostic accuracy, the crown-cut needle was superior to the conventional needle in detecting granulomas and histiocytes. This indicates greater potential for obtaining higher quality sample material with the crown-cut needle in cases of granulomatous inflammation.

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.

Endobronchial Ultrasound-Guided Transbronchial Forceps Biopsy: A Retrospective Bicentric Study Using the Olympus 1.5 mm Mini-Forceps. J Clin Med 2022; 11:jcm11164700. [PMID: 36012940 PMCID: PMC9410050 DOI: 10.3390/jcm11164700] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 07/31/2022] [Accepted: 08/09/2022] [Indexed: 11/17/2022] Open
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.

Abstract
Endobronchial ultrasound (EBUS)‐guided tissue acquisition (TA) performed by transbronchial needle aspiration (TBNA) is the main diagnostic procedure in mediastinal and hilar lymph node (LN) biopsy. EBUS‐guided intranodal forceps biopsy (EBUS‐IFB) and EBUS‐guided cryobiopsy can achieve higher diagnostic yield of lymphomas, uncommon tumors, and benign diseases. However, these techniques require the creation of a tract to insert biopsy devices, which may result in critical complications. Here, we report a rare case of airway stenosis (AS) that occurred after EBUS‐TA for mediastinal LN biopsy. An 80‐year‐old man had multiple pulmonary nodules and an enlarged mediastinal LN. EBUS‐TBNA and EBUS‐IFB were performed for histological diagnosis. Cutaneous adnexal carcinoma (CAC) was diagnosed. The patient underwent chemotherapy. Four months later, he was hospitalized for AS due to a tracheal tumor with dyspnea. Chest computed tomography and bronchoscopy revealed that the tracheal tumor was caused by invasion from the biopsied LN into the tracheal lumen by tract seeding (TS) caused by EBUS‐TA. Cryotherapy was performed. The tracheal tumor was pathologically consistent with CAC and is currently under control with radiotherapy. TS‐associated EBUS‐TA is rare but may increase in frequency with aggressive tissue sampling techniques. Bronchoscopists should perform EBUS‐TA with awareness of the potentially serious complications.

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
PURPOSE OF REVIEW Lung cancer is the leading cause of cancer-related deaths worldwide. In the absence of distant metastases, accurate mediastinal nodal staging determines treatment approaches to achieve most favourable outcomes for patients. Mediastinal staging differentiates N0/N1 disease from N2/N3 in surgical candidates. Likewise, presence of nodal involvement in nonsurgical candidates who are being considered for stereotactic body radiation therapy is also critical. This review article seeks to discuss the current options available for mediastinal staging in nonsmall cell lung cancer (NSCLC), particularly the role of bronchoscopy. RECENT FINDINGS Although several techniques are available to stage the mediastinum, bronchoscopy with EBUS-TBNA with or without EUS-FNA appears to be superior in most clinical situations based on its ability to concomitantly diagnose and stage at once, safety, accessibility to the widest array of lymph node stations, cost and low risk of complications. However, training and experience are required to achieve consistent diagnostic accuracy with EBUS-TBNA. SUMMARY EBUS-TBNA with or without EUS-FNA is considered the modality of choice in the diagnosis and staging of NSCLC in both surgical and nonsurgical candidates.

Abstract
Since the endobronchial ultrasound bronchoscope was introduced to clinical practice, endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has become the procedure of choice to sample hilar and mediastinal adenopathy. Multiple studies have been conducted in the last two decades to look at the different technical aspects of the procedure and their effects on the final cytopathological yield. In addition, newer modes of ultrasound scanning and newer tools with the potential to optimize the selection and sampling of the target lymph node have been introduced. These have the potential to reduce the number of passes, reduce the procedure time, and increase the diagnostic yield, especially in rare tumors and benign diseases. Herein, we review the latest updates related to the technical aspects of EBUS-TBNA and their effects on the final cytopathological yield in malignant and benign diseases.

Abstract
This is the case of a 15-y-old boy who presented with fever and back pain with MRI features of spondylitis. A CT-guided vertebral biopsy showed acute and chronic inflammatory cells and grew Pseudomonas aeruginosa on aerobic culture. The child was treated for 2 wk with antibiotics with no response. Meanwhile, he developed new lung, liver, and splenic lesions on CT imaging. Empiric antitubercular therapy was then started and continued for 8 wk during which time there was progressive clinical deterioration. At this time the patient underwent bronchoscopy with lavage and endoscopic ultrasound-guided subcarinal lymph node and lung biopsy. The Xpert MTB/Rif ULTRA was "trace positive" in the bronchoscopic lavage with indeterminate rifampicin resistance, while it was negative in lymph node and lung biopsy. The lymph node and lung biopsy histopathology showed nonspecific inflammatory changes with no granulomas or malignant cells. In view of the positive Xpert ULTRA with indeterminate rifampicin resistance and no response to first-line drugs, treatment with second-line antitubercular drugs was initiated. The clinical condition continued to deteriorate; here the imaging findings were reviewed again and repeat aspiration cytology and biopsy from intra-abdominal nodes was carried out. This yielded the diagnosis of Hodgkin lymphoma. The patient had stage IVB disease. He responded well to standard chemotherapy and is currently in remission. The case illustrates the need to avoid empiric therapy, repeat invasive procedures if so needed, choose the site/method of biopsy appropriately and interpret results of investigations carefully when evaluating a patient with pyrexia of unknown origin.

Abstract
Introduction: In recent years, there has been a growing development of molecularly targeted therapies for various types of solid tumors—in particular, in non-small-cell lung cancer (NSCLC). This has required the need for greater quantities of tissue that is able to support ancillary studies, alongside cyto-histological diagnoses for the assessment of molecular targets. Conventional TBNA (cTBNA) and EBUS-guided TBNA (EBUS-TBNA) have shown a high diagnostic yield for malignant mediastinal and/or hilar lymph node enlargement and peribronchial masses; however, few studies have compared these two procedures. We retrospectively compared TBNA patients (EBUS-TBNA and cTBNA) in order to determine the diagnostic yield and material adequacy for subsequent ancillary analyses. Materials and Methods: We retrospectively evaluated 318 patients with clinical suspicion of lung cancer or with disease recurrence. All of the patients underwent TBNA (either EBUS-TBNA or cTBNA) on enlarged mediastinal and/or hilar lymph nodes and peribronchial masses between January 2017 and June 2021 at the University Hospital of Pisa, Italy. After a definitive diagnosis, molecular analyses and an evaluation of PD-L1 expression were performed in the cases of adenocarcinoma, squamous cell carcinoma, and NSCLC, not otherwise specified (NOS). Results: EBUS-TBNA was performed in 199 patients and cTBNA was performed in 119 patients with 374 and 142 lymph nodes, respectively. The overall diagnostic yield for positive diagnoses was 59% (diagnostic rate of 61% in EBUS-TBNA, and 55% in cTBNA). Adenocarcinoma (ADC) was the most frequent diagnosis in both methods. EBUS-TBNA diagnostic adequacy was 72% for molecular analysis, while it was 55.5% for cTBNA, showing a statistical trend (p = 0.08) towards the significance of EBUS. The average percentage of neoplastic cells was also statistically different between the two methods (p = 0.05), reaching 51.19 ± 22.14 in EBUS-TBNA and 45.25 ± 22.84 in cTBNA. With regard to the PD-L1 protein expression, the percentage of positivity was similar in both procedures (86% in EBUS-TBNA, 85% in cTBNA). Conclusions: Conventional TBNA (cTBNA) and EBUS-guided TBNA (EBUS-TBNA) are minimally invasive diagnostic methods that are associated with a high diagnostic yield. However, EBUS-TBNA has an improved diagnostic adequacy for molecular analysis compared to cTBNA, and is associated with a higher average percentage of neoplastic cells.

Abstract
Sarcoidosis is a multi-system disease of unknown etiology characterized by the formation of granulomas in various organs. It affects people of all ethnic backgrounds and occurs at any time of life but is more frequent in African Americans and Scandinavians and in adults between 30 and 50 years of age. Sarcoidosis can affect any organ with a frequency varying according to ethnicity, sex and age. Intrathoracic involvement occurs in 90% of patients with symmetrical bilateral hilar adenopathy and/or diffuse lung micronodules, mainly along the lymphatic structures which are the most affected system. Among extrapulmonary manifestations, skin lesions, uveitis, liver or splenic involvement, peripheral and abdominal lymphadenopathy and peripheral arthritis are the most frequent with a prevalence of 25-50%. Finally, cardiac and neurological manifestations which can be the initial manifestation of sarcoidosis, as can be bilateral parotitis, nasosinusal or laryngeal signs, hypercalcemia and renal dysfunction, affect less than 10% of patients. The diagnosis is not standardized but is based on three major criteria: a compatible clinical and/or radiological presentation, the histological evidence of non-necrotizing granulomatous inflammation in one or more tissues and the exclusion of alternative causes of granulomatous disease. Certain clinical features are considered to be highly specific of the disease (e.g., Löfgren's syndrome, lupus pernio, Heerfordt's syndrome) and do not require histological confirmation. New diagnostic guidelines were recently published. Specific clinical criteria have been developed for the diagnosis of cardiac, neurological and ocular sarcoidosis. This article focuses on the clinical presentation and the common differentials that need to be considered when appropriate.
