Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has been used to diagnose and stage lung cancer. Acquire™ Pulmonary and Expect™ Pulmonary dedicated EBUS-TBNA needles were introduced as the Franseen and Lancet needles, respectively. It is still unclear whether the Franseen or Lancet needles yield a higher quality specimen especially focusing on next-generation sequencing-based molecular testing. METHODS A single-center, prospective study performed at the Chiba University Hospital randomly assigned patients to two groups: Group A, wherein the first and second EBUS-TBNA were performed using Lancet and Franseen needles, respectively, and Group B, wherein the first and second EBUS-TBNA were performed using Franseen and Lancet needles, respectively. Each specimen was compared and analyzed pathologically. The primary outcome was the histological tissue area except blood clot and the cellularity of each sample. We also examined the success rate of molecular testing. RESULTS Twelve patients who underwent EBUS-TBNA between November 2022 and February 2023 were enrolled in this study. The tissue area of the specimens obtained by the Franseen and Lancet needles was 13.3 ± 6.4 mm2 and 10.6 ± 6.3 mm2, respectively (P = .355). The tumor cellularity in the specimens obtained using the Franseen and Lancet needles was 54.0 ± 30.3 and 46.2 ± 36.3%, respectively (P = .608). The success rate of molecular testing using the single-pass sample by Franseen needle was 85.7 and 57.1% by Lancet needle. No serious complications were reported. CONCLUSIONS The Franseen needle tended to show a greater amount of specimen with higher tumor cellularity than the Lancet needle which may contribute higher success rate of molecular testing. Further studies must be conducted to validate the results of this study. KEY FINDINGS What is known and what is new? What is the implication, and what should change now?

Abstract
By searching lliteratures till January 5, 2022, we evaluated the role of the mediastinal nodal staging of endobronchial ultrasound-guided fine-needle aspiration (EBUS) and endoscopic ultrasound-guided fine-needle aspiration (EUS) in lung cancer. A total of 20 studies with 2,961 patients were included in this study. The pooled sensitivity, specificity, PLR, and NLR for EBUS were 0.79, 0.97, 27.29, and 0.25, respectively. EUS showed staging performance similar to EBUS. The staging performance was significantly improved when combining EBUS + EUS.

Abstract
Although often regarded as a protean illness with myriad clinical and imaging manifestations, neurosarcoidosis typically presents as recognizable syndromes that can be approached in a rational, systematic fashion. Understanding of neurosarcoidosis has progressed significantly in recent years, including updated diagnostic criteria and advances in treatment. The diagnosis of neurosarcoidosis is established by the clinical syndrome, imaging and histopathological findings, and exclusion of other causes. Mounting evidence supports the use of tumor necrosis factor inhibitors as an important addition to the therapeutic armamentarium, along with glucocorticoids and steroid-sparing cytotoxic immunosuppressants. In this narrative review, we summarize recent advances in the diagnosis and treatment of neurosarcoidosis.

Abstract
The use of convex-probe endobronchial ultrasound (CP-EBUS) has revolutionized bronchoscopy. It has provided the option of a relatively safe, minimally invasive approach for the assessment of various intrathoracic diseases. In current practice, its most dramatic impact has been on the diagnosing and staging of lung cancer. It has served as an invaluable tool that has replaced mediastinoscopy in a variety of clinical scenarios. Many pulmonologists and thoracic surgeons consider CP-EBUS the most significant milestone in bronchoscopy after the development of the flexible bronchoscope itself. In this review, we summarize the historical aspects, current indications, technical approach, and future direction of CP-EBUS.

The combination of endobronchial elastography and sonographic findings during endobronchial ultrasound-guided transbronchial needle aspiration for predicting nodal metastasis. Thorac Cancer 2019; 10:2000-2005. [PMID: 31474004 PMCID: PMC6775026 DOI: 10.1111/1759-7714.13186] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2019] [Revised: 08/15/2019] [Accepted: 08/15/2019] [Indexed: 12/21/2022] Open
Abstract
Background During endobronchial ultrasound‐guided transbronchial needle aspiration (EBUS‐TBNA), the sonographic findings of B‐mode imaging, as well as endobronchial elastography, can be obtained noninvasively and used for the prediction of nodal metastasis. Methods Patients with lung cancer or suspected lung cancer who underwent EBUS‐TBNA were recorded prospectively and reviewed retrospectively. Both the B‐mode sonographic and elastographic findings were independently evaluated for each lymph node. The sonographic features were classified according to previously published criteria. If oval shape, indistinct margins, homogenous echogenicity, and the absence of coagulation necrosis sign were all observed by B‐mode imaging, then the lymph node was judged to be benign by sonographic imaging. In addition, if the stiffer area comprised more than 31% of the entire lymph node area, then the lymph node was judged to be malignant by elastography. We compared the results of these imaging‐based predictions with the pathological diagnoses. Results The prevalence of nodal metastasis was 78/228 (34.2%). B‐mode sonography predicted 95.8% of benign lymph nodes, and elastography predicted 72.1% of malignant lymph nodes. By combining the two modalities, 59 of 71 (83.1%) lymph nodes judged as malignant by both analyses were pathologically proven to be malignant, and 101 of 105 (96.2%) lymph nodes judged as benign by both analyses were pathologically proven to be benign. Conclusion The combination of elastography and sonographic findings showed good sensitivity and a high negative predictive value, which may facilitate selecting the most suspicious lymph nodes for biopsy. Key points Significant findings of the study. The combination of endobronchial elastography and sonography resulted in a higher diagnostic yield than either modality alone for predicting benign and malignant lymph nodes in patients with lung cancer. What this study adds. The combination of endobronchial elastography and sonography will help clinicians identify the most suspicious lymph nodes for puncturing during EBUS‐TBNA, which may improve the efficiency of EBUS‐TBNA.

Abstract
Since the development of third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors for lung cancer treatment, the need for a rebiopsy has increased. To select an appropriate therapeutic regimen, the genetic alterations in cancerous tissue should be determined. A rebiopsy plays an important role in the treatment of patients with diseases that are refractory to the previous generation of EGFR tyrosine kinase inhibitors. Cell-free DNA-based exploration is useful for determining the cause of treatment resistance in cases in which a rebiopsy is difficult; however, this method cannot detect histologic changes (a mechanism of resistance), which may lead to the selection of nonoptimum therapeutic agents. We herein report a case in which EGFR mutation-positive (exon 19 deletion) lung cancer was successfully treated with an appropriate chemotherapeutic regimen after disease progression. The regimen was selected based on the precise evaluation of a rebiopsy specimen, which determined the histologic type and detected a gene mutation.

Abstract
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has been widely used in Japan. The guidelines of the American College of Chest Physicians has recommended that EBUS-TBNA should be performed by well-trained operators who can perform highly accurate procedures, but the indicators of the degree of experience and training are unclear. In our department, physicians who do not have enough experience perform EBUS-TBNA under the supervision of bronchoscopic instructors who have EBUS-TBNA techniques (Board Certified Member of the Japan Society for Respiratory Endoscopy) after guidance and training in EBUS-TBNA using a simulator as an operator and helper. In order to evaluate the influence of the experience and training of EBUS-TBNA on diagnostic accuracy and safety, we retrospectively compared the diagnostic accuracy and safety of EBUS-TBNA performed by physicians within one year of experience of EBUS-TBNA and those performed by physicians with more than one year of experience. A total of 111 cases (148 lesions) who were eventually diagnosed as having primary lung cancer and underwent EBUS-TBNA in our department between April 2014 and January 2016 were divided into two groups. Group A (43 cases, 57 lesions) was examined by third-year doctors within one year of experience of EBUS-TBNA, and group B (68 cases, 91 lesions) was examined by doctors with four or more years of experience and with more than one year of experience of EBUS-TBNA. Diagnostic rate, examination time, and complications were evaluated. There were no significant differences between the two groups in the diagnostic rate (A, 89.5% vs. B, 90.1%, P = 1.0) or examination time (A, 27 min vs. B, 23 min, P = 0.149), and no complications were observed in either group. This study suggests that even less-experienced physicians may safely perform EBUS-TBNA as well as moderately-experienced physicians with more than 1 year experience of EBUS-TBNA with similar diagnostic rates when proper training and supervision are supplied.

Abstract
Background and Objectives: Since the introduction of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), most pulmonary centers use this technique exclusively for mediastinal lymph node (LN) sampling. Conventional “blind” TBNA (cTBNA), however, is cheaper, more accessible, provides more tissue, and requires less training. We evaluated whether sampling of mediastinal LN using EBUS-TBNA or cTBNA according to a predefined set of criteria provides acceptable diagnostic yield. Materials and Methods: Sampling method was determined prospectively according to a predefined set of criteria based on LN station, LN size, and presumed diagnosis. Sensitivity, specificity, positive, and negative predictive value were evaluated for each modality. Results: One hundred and eighty-six biopsies were carried out over a 3-year period (86 cTBNA, 100 EBUS-TBNA). Seventy-seven percent of LN biopsied by EBUS-TBNA were <20 mm, while 83% of cTBNA biopsies were ≥20 mm. Most common sites of cTBNA sampling were station 7, 4R, and 11R as opposed to 7, 11R, 4R, and 4 L in the case of EBUS-TBNA. Most common EBUS-TBNA diagnosis was malignancy versus sarcoidosis in cTBNA. EBUS-TBNA and cTBNA both had a true positive yield of 65%, but EBUS-TBNA had a higher true negative rate (21% vs. 2% for cTBNA) and a lower false negative rate (7% vs. 28%). Sensitivity, specificity, positive predictive value, and negative predictive value for EBUS-TBNA were 90%, 100%, 100%, and 75%, respectively, and for cTBNA were 68%, 100%, 100%, and 7%, respectively. Conclusion: A stepwise approach based on LN size, station, and presumed diagnosis may be a reasonable, cost-effective approach in choosing between cTBNA and EBUS-TBNA.

Abstract
BACKGROUND Flexible bronchoscopy with endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA) is increasingly being used to obtain pathology specimens for diagnosis of sarcoidosis. There is wide variation in reported diagnostic yield in literature. New TBNA needles are available in the market but data are lacking about their diagnostic yield especially for sarcoidosis. This study reports the diagnostic yield of bronchoscopy with EBUS-TBNA using ViziShot FLEX 19-G needle in a series of patients with suspected sarcoidosis. METHODS This is a retrospective chart review for diagnostic yield of the 19-G EBUS-TBNA needle for suspected sarcoidosis. RESULTS Eighty-six EBUS bronchoscopies were performed, 15 were done with clinical suspicion of sarcoidosis. The 19-G needle was used for all cases of suspected sarcoidosis. The procedure was diagnostic of sarcoidosis in 14 (93.3%) patients by TBNA with 1 nondiagnostic bronchoscopy. Procedural diagnostic yield was 93.3%. Eighty-five percent (28/33) of sampled lymph nodes were positive for noncaseating granulomas. The yield of transbronchial lung biopsy (TBLB) and endobronchial lung biopsy was 38% (5/13) and 43% (6/14), respectively. TBLB and endobronchial lung biopsy did not add to the diagnostic yield of the procedure. No significant adverse events were noted. CONCLUSION This series reports a higher diagnostic yield than most other published studies and opens platform for direct comparison of each available needle. It also adds to the safety data for this larger needle. In addition, it raises doubt into utility of TBLB for diagnosis of sarcoidosis, which can increase the procedural complications.

Use of an Additional 19-G EBUS-TBNA Needle Increases the Diagnostic Yield of EBUS-TBNA. J Bronchology Interv Pulmonol 2018; 25:269-273.

Abstract
BACKGROUND Although endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has an excellent diagnostic yield, there remain cases where the diagnosis is not obtained. We hypothesized that additional sampling with a 19-G EBUS-TBNA needle may increase diagnostic yield in a subset of cases where additional tissue sampling was required. METHODS Indications for use of the 19-G needle following 22-G sampling with rapid on-site cytologic examination were: (1) diagnostic uncertainty of the on-site cytopathologist (eg, nondiagnostic, probable lymphoma, etc.), (2) non-small cell lung cancer with probable need for molecular genetic and/or PD-L1 testing, or (3) need for a larger tissue sample for consideration of inclusion in a research protocol. RESULTS A 19-G EBUS-TBNA needle was utilized following standard sampling with a 22-G needle in 48 patients (50 sites) during the same procedure. Although the diagnostic yield between the needles was equivalent, the concordance rate was only 83%. The 19-G determined a diagnosis in 4 additional patients (8%) and provided additional histopathologic information in 6 other cases (12%). Conversely, in 3 cases (6%) diagnostic information was provided only by the 22-G needle. Compared with 22-G EBUS-TBNA alone, sampling with both the 22- and 19-G EBUS needles resulted in an increase in diagnostic yield from 92% to 99% (P=0.045) and a number needed to sample of 13 patients to provide one additional diagnosis. There were no significant complications. CONCLUSION In select cases where additional tissue may be needed, sampling with a 19-G EBUS needle following standard aspiration with a 22-G needle results in an increase in diagnostic yield.

Abstract
Endobronchial elastography is a novel imaging technology which visualizes the relative stiffness of the targeted tissue. Endobronchial elastography can be used for differentiating malignant and benign lymph nodes during nodal staging in patients with lung cancer. Another possible utility of endobronchial elastography would be targeting high-risk area within the intrathoracic lymph node. During nodal staging using endosonographic technology, a false negative result was known as a limitation of needle biopsy modality that could be caused by the micrometastasis within the lymph node. We report the identification of mediastinal lymph node metastasis in a patient with squamous cell carcinoma by visualization of the metastatic site using endobronchial elastography.

Flow cytometric analysis of lymphocyte profiles in mediastinal lymphadenopathy of sarcoidosis. PLoS One 2018; 13:e0206972.

Abstract
Lymphocyte profiles in mediastinal lymph nodes may reflect the immune status of patients with sarcoidosis. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is useful for the diagnosis of diseases with mediastinal lymphadenopathy including sarcoidosis. The purpose of this study was to determine lymphocyte profiles of lymph nodes in sarcoidosis by analyzing EBUS-TBNA samples. We prepared single cell suspensions from EBUS-TBNA samples of mediastinal lymph nodes from patients with sarcoidosis or lung cancer and analyzed surface markers (CD3, CD4, CD8, CD19, CD25) and FoxP3 expression in the resultant lymphocytes using flow cytometry. We studied 26 patients with sarcoidosis and 16 with lung cancer with mediastinal lymph node metastases. In sarcoidosis, the CD4/CD8 ratio was significantly more elevated in lymph nodes than in bronchoalveolar lavage fluid (P<0.001), although both were strongly correlated. The CD4/CD8 ratio was significantly higher in stage I than in stage II both in the BAL fluid and lymph nodes. When compared with lung cancer lymph node metastasis, the CD4/CD8 ratio was significantly higher in sarcoidosis, whereas the CD3/CD19 ratio was significantly higher in lung cancer. The proportion of regulatory T cells (CD4+, CD25+, FoxP3 high) did not differ between sarcoidosis and lung cancer samples. Lymphocyte profiles in mediastinal lymphadenopathy can be analyzed by flow cytometry of EBUS-TBNA samples. These findings might help elucidate the immunopathology of sarcoidosis.

Abstract
Training for endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has focused on the procedure itself; however, the techniques for obtaining adequate sample are also important for achieving a pathological diagnosis as well as for molecular testing. The aim of this study was to evaluate the feasibility and efficacy of a biosimulator for training subjects in adequate sample acquisition during EBUS-TBNA.A total of 19 bronchoscopists voluntarily participated in this study. A biosimulator (ArtiCHEST, HARADA Corporation, Tokyo, Japan) was used for the training. After a 10-minute briefing, the first pass was performed by pairs of trainees. The trainees then received a 30-minute lecture that focused on the acquisition of samples using EBUS-TBNA. The trainees next performed their second pass under the supervision of the trainers. Each participant obtained a cytological smear that was coded and evaluated for quantity as well as quality by an independent cytotechnologist.The trainees had an average of 5.9 years of bronchoscopy experience. With regard to the quantity evaluation, 9 (47.4%) subjects sampled a greater number of lymphocytes on the second pass than on the first, whereas 2 were better on the first pass, and the others sampled roughly the same amount both times. With regard to the quality assessment, 9 (47.4%) subjects obtained better quality samples on the second pass, whereas the quality of the first and second pass was deemed to be roughly the same for the remaining subjects.A biosimulator can be used to train doctors in specimen acquisition and evaluate their skills with sampling using EBUS-TBNA.
