Abstract
INTRODUCTION While mediastinoscopy is considered the gold standard for mediastinal node sampling, it is to some extent being superseded by endobronchial ultrasound. The objective of this study was to evaluate the different practices in our center regarding mediastinal lymph node sampling in lung cancer patients. METHODS Data were collected from patients having undergone mediastinal lymph node sampling by video-assisted-mediastinoscopy (VM) or by endobronchial ultrasound (EBUS) in our center between August 2020 and July 2023. The modalities of the two procedures and their diagnostic accuracy were analyzed, as was their evolution over time. RESULTS The 362 patients comprised 217 who were sampled by EBUS and 145 by VM. Overall, the procedures became more frequent, with EBUS tending to supersede VM. The number of harvested lymph nodes gradually grew, and less unforeseen lymph node invasion and upstaging occurred. CONCLUSION The arrival in our center of endobronchial ultrasound yielded an overall increase of lymph node sampling despite a decrease in the number of mediastinoscopy procedures performed. Reinforced compliance with guidelines is needed to improve the diagnostic accuracy of these techniques and to better ensure quality of care.

Front Med (Lausanne) 2024; 11:1383600. [PMID: 38799146 PMCID: PMC11116619 DOI: 10.3389/fmed.2024.1383600] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Accepted: 04/22/2024] [Indexed: 05/29/2024] Open
Abstract
Background Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive technique for biopsy of lung, peri-pulmonary tissue and lymph nodes under real-time ultrasound-guided biopsy. It is used in the diagnosis and/or staging of benign and malignant pulmonary and non-pulmonary diseases. Our study is based on a large sample size, in a diversified population which provides a representative real-world cohort for analysis. Methods Patients who underwent EBUS-TBNA procedure between September 2019 and August 2022 were included in this retrospective study. For cases diagnosed as benign and unclassified lesions by EBUS-TBNA, the final diagnosis was determined by further invasive surgery or a combination of therapy and clinical follow-up for at least 6 months. Results A total of 618 patients were included in the study, including 182 females (29.4%) and 436 males (70.6%). The mean age of all patients was 61.9 ± 10.5 years. These patients were successfully punctured by EBUS-TBNA to obtain pathological results. The pathological diagnosis results of EBUS-TBNA were compared with the final clinical diagnosis results as follows: 133 cases (21.5%) of benign lesions and 485 cases (78.5%) of malignant lesions were finally diagnosed. Among them, the pathological diagnosis was obtained by EBUS-TBNA in 546 patients (88.3%) (464 malignant lesions and 82 benign conditions), while EBUS-TBNA was unable to define diagnosis in 72 patients (11.6%). 20/72 non-diagnostic EBUS-TBNA were true negative. The overall diagnostic sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of EBUS-TBNA were 91.3%, 100%, 100%, 27.8%, and 91.6% [95% confidence interval (CI): 89.1-93.6%], respectively. In this study, only one case had active bleeding without serious complications during the EBUS-TBNA procedure. Conclusion Given its low invasiveness, high diagnostic accuracy, and safety, EBUS-TBNA is worth promoting in thoracic lesions.

Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is routinely performed to confirm a lung cancer diagnosis and/or to clinically stage disease. EBUS-TBNA findings may be used to determine whether patients can be offered potentially curative surgery. In this study, we evaluated the reporting in our service of EBUS-TBNA cytology for early-stage (operable) non-small cell lung cancer (NSCLC), focusing on diagnostic accuracy and analyzing cases with discordant cytologic and post-surgical histopathologic conclusions. METHODS Cytology slides and cytopathology reports of 120 NSCLC patients who had undergone EBUS-TBNA and lobectomy in our hospital system between 2015 and 2021 were retrospectively reviewed. RESULTS Of 290 lymph nodes (110 cases) able to be reviewed, interpretation of 48 lymph nodes was discordant with the original cytopathology report. This included 31 lymph nodes originally reported as adequate, which were found to be non-diagnostic on review. The diagnostic accuracy (benign/malignant) of lymph nodes that were sampled at EBUS-TBNA and excised at surgery was 89%. Specific examination of cases where EBUS-TBNA cytology did not reflect post-surgical findings illustrated important features and limitations of the procedure. These included potential misclassification of lymph node stations, the presence of multiple, variably involved nodes at lymph node stations, and the failure to detect small volume disease. CONCLUSIONS Continuous evaluation of EBUS-TBNA performance identifies technical limitations and areas of improvement for cytopathology reporting. This is increasingly important in an era where lung cancer screening is expected to increase diagnosis of early-stage disease and with the advent of novel treatments, including non-surgical management options.

Abstract
Background Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is an innovative tool for diagnosing mediastinal diseases. We investigated the factors affecting the diagnostic yield of EBUS-TBNA and evaluated whether the effects of these factors (number of biopsies, core tissue acquisition rate, and diameter and volume of tissue) vary depending on computed tomography (CT) and/or positron emission tomography (PET)/CT results. Methods We retrospectively analyzed lung cancer patients who underwent EBUS-TBNA at Korea University Ansan Hospital (January 2019-December 2022). Patients in whom EBUS-TBNA failed and those with missing diameter or volume data and no imaging data interpretation were excluded. Subgroup analysis was performed by dividing the patients into None (no cancer detected on CT or PET/CT), Either (cancer detected on either CT or PET/CT), and Both (cancer detected on both CT and PET/CT) groups. Results In all, 228 patients were enrolled; 351 lymph node stations were analyzed. The median age of the patients was 69 years (male, 76.8%). Adenocarcinoma (28.5%) was the most common diagnosis. EBUS-TBNA was predominantly performed at station #4R (30.5%). Each examination involved two stations with a total procedure time of 30 minutes. An increased number of passes led to a higher diagnostic yield for EBUS-TBNA (P<0.001). Additionally, successful tissue sampling was associated with a large diameter (P=0.016) and volume (P=0.002) of the tissue. The effect of these factors was modified by imaging results. In the None and Either groups, an increase in the pass number was correlated with an increased diagnostic yield (adjusted P=0.003 and 0.007, respectively). However, in the Both group, it was not significant and remained at a suggestive level (P=0.304). The diameter and volume did not differ significantly across subgroups (adjusted P>0.05). Conclusions Increasing the number of passes during EBUS-TBNA can maximize the diagnostic yield, especially when CT and/or PET/CT results are inconclusive.

Abstract
We present the case of a patient with severe complications from mediastinal bleeding after endosonographically guided transbronchial cryobiopsy (EBUS-TBKB) with suspected advanced lymphoma. The EBUS-TBKB is a new effective examination method in interventional pneumology for the diagnosis of diseases with mediastinal lymph node enlargement and intrathoracic tumors, with which large tissue cylinders in the mediastinum can be obtained. Due to the high diagnostic value of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for the clarification of lymphadenopathy, the examination should not be carried out as a routine application. Indications for a primary EBUS-TBKB arise when there is a suspicion of intrathoracic malignant lymphomas or other rare tumors in which extensive unfragmented tissue material is required for diagnosis. A rare complication that has not yet been described in the literature is a hematomediastinum, so that a careful risk assessment of possible bleeding complications should be carried out before intervention and the more invasive mediastinoscopy can be a safer examination method.

Abstract
Talaromyces marneffei (T. marneffei) is one of the most important opportunistic human pathogens endemic in Southeast Asia. Talaromycosis, which was once regarded as an opportunistic infectious disease in patients with acquired immunodeficiency syndrome, is being increasingly reported in HIV-negative populations. Since T. marneffei infection can be localized or disseminated, patients may present with a variety of symptoms. However, mediastinal infection attributed to T. marneffei is extremely rare. We report the case of a 32-year-old female who manifested a large mediastinal mass and was eventually diagnosed as acute T. marneffei mediastinitis. The patient was HIV-negative and had no direct contact with intermediate hosts. We successfully managed to treat the patient with inhaled amphotericin B deoxycholate and observed lesion absorption in subsequent CT examinations. To our knowledge, this is the first published case of T. marneffei mediastinitis and first use of inhaled antifungal monotherapy on patients with T. marneffei infection.

Abstract
RATIONALE Current guidelines of non-small cell lung cancer (NSCLC) mediastinal staging recommend starting invasive staging with endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). However, the indication to confirm a negative result of EBUS-TBNA by means of video-assisted mediastinoscopy (VAM) prior to resection differs in every guideline. OBJECTIVE Our aim was to evaluate the current evidence regarding the added value of confirmatory VAM after a negative EBUS-TBNA for mediastinal staging in patients with NSCLC. METHODS Systematic searches of studies on EBUS-TBNA for NSCLC mediastinal staging with or without confirmatory VAM but with surgical confirmation of negative results were conducted in accordance with PRISMA statement in PubMed, SCOPUS, Cochrane and Guidelines from 2005 through November 2021. In the meta-analysis the sensitivity of confirmatory VAM after a negative EBUS-TBNA, the sensitivity and negative predictive value (NPV) of the combination EBUS-TBNA plus confirmatory VAM, alongside the number of confirmatory VAM required to detect additional N2/3 disease (number needed to treat [NNT]), in patients with a previous negative EBUS-TBNA were estimated. RESULTS 5412 articles were found, of which 29 studies were included. Random effects meta-analysis showed a sensitivity of 66.9% (95% CI: 55.8%-77.1%) for confirmatory VAM, and 96.7% (95% CI: 95.1%- 98%) for the combination EBUS-TBNA plus confirmatory VAM. NPV in studies with confirmatory VAM increased of 79.2% (95% CI: 71.4%-86.1%) for EBUS-TBNA alone to 91.8% (95% CI: 87.1%-95.5%) for EBUS-TBNA plus confirmatory VAM. The NNT of confirmatory VAM in patients with a previous negative EBUS-TBNA was 23.8 (95% CI: 19.3-31.2) CONCLUSIONS: Confirmatory VAM after negative EBUS-TBNA reduces the rate of unforeseen N2/3 disease, but with a high NNT, and should be recommended only to certain cases yet to be defined.

Abstract
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive bronchoscopic procedure, well established as a diagnostic modality of first choice for diagnosis and staging of non-small cell lung cancer (NSCLC). The therapeutic decisions for advanced NSCLC require comprehensive profiling of actionable mutations, which is currently considered to be an essential part of the diagnostic process. The purpose of this study was to evaluate the utility of EBUS-TBNA cytology specimen for histological subtyping, molecular profiling of NSCLC by massive parallel sequencing (MPS), as well as for PD-L1 analysis. A retrospective review of 806 EBUS bronchoscopies was performed, resulting in a cohort of 132 consecutive patients with EBUS-TBNA specimens showing NSCLC cells in lymph nodes. Data on patient demographics, radiology features of the suspected tumor and mediastinal engagement, lymph nodes sampled, the histopathological subtype of NSCLC, and performed molecular analysis were collected. The EBUS-TBNA specimen proved sufficient for subtyping NSCLC in 83% and analysis of treatment predictive biomarkers in 77% (MPS in 53%). The adequacy of the EBUS-TBNA specimen was 69% for EGFR gene mutation analysis, 49% for analysis of ALK rearrangement, 36% for ROS1 rearrangement, and 33% for analysis of PD-L1. The findings of our study confirm that EBUS-TBNA cytology aspirate is appropriate for diagnosis and subtyping of NSCLC and largely also for treatment predictive molecular testing, although more data is needed on the utility of EBUS cytology specimen for MPS and PD-L1 analysis.

Abstract
INTRODUCTION Lung cancer is the most common cancer in the world, both in terms of new cases and deaths. Almost a fifth of all cancer deaths worldwide are due to lung cancers. Our aim was to evaluate the utility of endobronchial ultrasound-guided trans-bronchial needle aspiration (EBUS-TBNA) for lymph node staging in patients with lung cancer. METHODS We performed a retrospective study on a total of 427 patients who underwent EBUS-TBNA sampling from January 2020 to December 2020 and a total of 610 lymph nodes were sampled. There were 322 men (mean age: 66.3 and range: 20-87) and 105 women (mean age: 65.9 and range: 18-81). RESULTS Cytological diagnosis revealed that 55 patients had adenocarcinoma, 28 squamous cell carcinoma, 43 neuroendocrine tumours, 34 non-small cell carcinoma not otherwise specified, 21 metastasis from extra-thoracic malignancy, 7 atypical cells suspicious for malignancy, and 239 patients had normal or reactive lymph nodes or non-neoplastic diagnosis. The diagnostic accuracy, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were 91%, 88.3%, 100%, 100% and 89.2%, respectively. CONCLUSION EBUS-TBNA is a safe technique with high accuracy, sensitivity, specificity, PPV, and NPV. It is an excellent option for the diagnostic approach of patients with lymphadenopathy or intra-thoracic lesions as well as for the staging of malignancies.

Abstract
INTRODUCTION Bronchoscopy is the main method in the diagnosis of various lung diseases. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is the most modern bronchoscopic technique useful in diagnosis and staging of lung cancer (LC). OBJECTIVE The aim of the study was to assess the yield of bronchoscopy in patients with suspected various respiratory diseases including LC. In particular, we examined the efficiency of different biopsy techniques in the diagnosis of LC in correlation with its localisation and pathomorphological type. PATIENTS AND METHODS The results of pathomorphological examinations from 5279 bronchoscopies performed in 2016-2018 were analysed. The material was collected with EBUS-TBNA, endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) and endobronchial forceps biopsy. Clinical and demographic factors were analysed using the Fisher χ2 test. RESULTS 5279 patients were diagnosed due to various respiratory symptoms. LC was confirmed in 36.42% of patients. 40.81% of patients had no definitive pathomorphological diagnosis. Among patients with LC, the most frequent diagnosis was non-small cell LC: squamous cell lung cancer (SCC)-32.07% and adenocarcinoma (AC)-30.61%, then small cell LC-25.83% and not otherwise specified non-small cell lung cancer (NSCLC-NOS)-11.49%. Diagnosis of SCC was obtained significantly more often (χ2=43.143, p<0.000001) by forceps biopsy (41.09%) than by EBUS-TBNA/EUS-FNA (26.62%). On the contrary, diagnosis of AC or NSCLC-NOS was significantly more often (χ2=20.394, p<0.000007, and χ2=3.902, p<0.05, respectively) observed in EBUS-TBNA/EUS-FNA (34.31% and 12.6%) than in endobronchial biopsies (24.52% and 9.64%). CONCLUSIONS The use of bronchoscopy in the diagnosis of various lung diseases is vital but also has many limitations. Effectiveness of EBUS-TBNA and endobronchial forceps biopsy in the diagnosis of lung cancer is strongly affected by tumour localisation and type of cancer.

Abstract
OBJECTIVE This study set out to enhance the positive detection rate of lung tumors, diagnosis of nodular lesions and improve the accuracy of lung cancer classification by evaluating the clinical value of autofluorescence bronchoscopy (AFB). METHODS Forceps biopsy, brush biopsy, needle aspiration, and washing techniques were performed alone and in combination with AFB among 38 subjects who were analyzed cytologically and histologically. RESULTS Our results showed that 33 out of 38 patients were diagnosed with lung cancer, with an overall positive diagnostic rate of 86.8% when the combined methods and AFB was performed; the positive diagnostic rates obtained by forceps, needle aspiration, brush biopsy and washing methods were 68.4%, 84.2%, 55.3% and 36.8%, respectively. Compared to the overall positive rate, the positive diagnostic rates detected by forceps and needle aspiration were not statistically significant (P>0.05). However, the positive rates gained by the brush biopsy and washing method were statistically significant (P<0.01). In addition, we compared the 38 cases evaluated with AFB and 43 cases evaluated with "traditional" white light bronchoscopy (WLB), using the same methods. CONCLUSIONS AFB and WLB markedly improved the positive diagnosis rate when combined with forceps and needle aspiration. The overall positive diagnostic rate of lung cancer scanned by WLB was increased from 60.5% to 86.8% (P<0.01) by using the combined methods of forceps, brush biopsy, needle aspiration and washing. Moreover, the accuracy of lung cancer classification combined with cytology and cell immunohistochemistry was improved. These results showed that a variety of inspection techniques and diagnostic technologies effectively play a complementary role in the diagnosis and classification of lung cancer.

Abstract
Lung cancer remains one of the most aggressive solid tumors with an overall poor prognosis. Molecular studies carried out on lung tumors during treatment have shown the phenomenon of clonal evolution, thereby promoting the occurrence of a temporal heterogeneity of the tumor. Therefore, the biology of lung cancer is interesting. Cancer stem cells (CSCs) are involved in tumor initiation and metastasis. Aging is still the most important risk factor for lung cancer development. Spontaneously occurring mutations accumulate in normal stem cells or/and progenitor cells by human life resulting in the formation of CSCs. Deepening knowledge of these complex processes and improving early recognition and markers of predictive value are of utmost importance. In this paper, we discuss the CSC hypothesis with an emphasis on age-related changes that initiate carcinogenesis. We analyze the current literature in the field, describe our own experience in CSC investigation and discuss the technical challenges with special emphasis on liquid biopsy.
