OBJECTIVE: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive diagnostic test with a high diagnostic yield for suspicious central pulmonary lesions and for mediastinal lymph node staging. The main objective of this study was to describe the diagnostic yield of EBUS-TBNA for mediastinal lymph node staging in patients with suspected lung cancer. METHODS: Prospective study of patients undergoing EBUS-TBNA for diagnosis. Patients ≥ 18 years of age were recruited between July of 2010 and August of 2013. We recorded demographic variables, radiological characteristics provided by axial CT of the chest, location of the lesion in the mediastinum as per the International Association for the Study of Lung Cancer classification, and definitive diagnostic result (EBUS with a diagnostic biopsy or a definitive diagnostic method). RESULTS: Our analysis included 354 biopsies, from 145 patients. Of those 145 patients, 54.48% were male. The mean age was 63.75 years. The mean lymph node size was 15.03 mm, and 90 lymph nodes were smaller than 10.0 mm. The EBUS-TBNA method showed a sensitivity of 91.17%, a specificity of 100.0%, and a negative predictive value of 92.9%. The most common histological diagnosis was adenocarcinoma. CONCLUSIONS: EBUS-TBNA is a diagnostic tool that yields satisfactory results in the staging of neoplastic mediastinal lesions.

Objectives: Aim of this comparative study was to assess the accuracy of computed tomography (CT) and endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) for mediastinal lymph node staging in cases of lymph node enlargement due to anthracosis and other benign conditions. Methods: In a retrospective analysis we report on the MSCT findings of 39 patients (28 males, 11 females) with EBUS-TBNA confirmed diagnosis of 53 enlarged lymph nodes due to anthracosis. A control group comprised 20 consecutive patients with 27 enlarged lymph nodes (11 males, 9 females) due to chronic lymphadenopathy (n = 14) or sarcoidosis (n = 13). Results: No significant differences were observed between the two groups regarding size (mean short axis diameter 13.7mm vs. 14.5mm), shape (most often oval) or presence of lymph node confluence (32.1% vs. 33.3%), contrast enhancement (3.8% vs. 3.7%), and fatty involution (3.8% vs. 3.7%). In comparison with the control group anthracotic lymph nodes were significantly less often ill-defined in EBUS (5.7 vs. 25.9, p = 0.025) as well as in CT (1.9% vs. 18.5%, p = 0.01), but more often showed calcifications in CT (24.5% vs. 3.7%, p = 0.017). Lymph node colliquation was seen neither in anthracosis nor in other benign conditions. Conclusions: Mediastinal lymph node enlargement due to anthracosis, lymphadenopathy and sarcoidosis show some different findings in EBUS and CT but cannot definitely be differentiated. Advances in knowledge: Radiologists should be aware of mediastinal lymph node enlargement due to anthracosis.

Site Evaluation

Trans-bronchial needle aspiration allows lymph node sampling in several thoracic conditions; the ability of Rapid On-Site Evaluation (ROSE) to predict the final diagnosis in this setting has not been well characterized. We performed a retrospective study to establish the utility of ROSE in the diagnosis of thoracic diseases with mediastinal lymph node involvement. We retrospectively reviewed 297 patients with hilar-mediastinal lymph node enlargement detected at CT scan from January 2013 to April 2016. 201 patients underwent conventional TBNA; in 96 patients, TBNA procedure was performed by on-site presence of a team of pathologists and research morphologists. Lung neoplasms, sarcoidosis, infections and lymphoma were the most common diseases diagnosed with TBNA samples. TBNA simultaneously performed in combination with ROSE produced an increase in percentage of appropriate samples compared to single cTBNA (adequate samples cTBNA vs ROSE-TBNA: 73% vs 81%; p<0.05). Our observations indicate an increase in adequacy of fine needle aspirations and increased diagnostic yield in the ROSE group. In conclusions, ROSE may serve to reduce procedure time and enhance sample triaging therefore limiting the need for further invasive diagnostic testing.

High Diagnostic Yield

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive modality for mediastinal lymph node staging in lung cancer patients as well as for the diagnosis of mediastinal and hilar adenopathy. The high diagnostic yield of EBUS-TBNA for lymph node staging has been shown in systematic reviews and meta-analysis. It has attracted physicians and surgeons as an alternative modality to surgical biopsy for the assessment of patients with enlarged mediastinal and/or hilar lymph nodes. Cell blocks obtained by EBUS-TBNA can be applicable not only for pathologic diagnosis but also for further investigations such as immunohistochemistry and fluorescence in situ hybridization. In addition, samples obtained by EBUS-TBNA can also be used for molecular analysis. Unlike regular bronchoscopy, EBUS-TBNA uses the convex probe EBUS with an ultrasound probe on the tip of a flexible bronchoscope. It is important for the bronchoscopist to fully understand the mediastinal anatomy and be able to correlate it with the ultrasound images for a successful EBUS-TBNA. The dedicated transbronchial needle used for EBUS-TBNA is somewhat different from an ordinary transbronchial biopsy forceps. Training is mandatory for achieving high diagnostic yield without complications. The learning curve of EBUS-TBNA is different from each physician, and continuous training program will be needed for impartiality. This article explains the detailed techniques of EBUS-TBNA to master this innovative procedure.

Transbronchial Needle Aspiration

Abstract Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) technique provides a complementary assessment of the areas of mediastinal lymph node involvement, and allows sampling of suspected lymph nodes. But, the usefulness of EBUS-TBNA in assessing all areas of mediastinal lymph nodes is little known and it seems that such assess is dependent to various factors related to the patient's condition and especially the characteristics of local lymph nodes. We aimed to evaluate the utility of EBUS-TBNA in assessing mediastinal lymph nodes and the factors associated with this utility.Methods: This cross-sectional study was performed on 40 patients suspected to mediastinal lymphadenopathy scheduled for assessment by EBUS-TBNA and mediastinoscopy. The diagnostic yield of EBUS-TBNA to mediastinal lymph nodes was evaluated and non diagnostic cases evaluated by mediastinoscopy .Results: In evaluation with EBUS-TBNA, the diagnostic yield of EBUS in assess to mediastinal lymph nodes including 34 out of 40 cases was equal to 85%. The size of lymph node (lower than 10mm), the area of sample (left and right upper paratracheal), and the nature of the lymph node sample (benign type) were associated with lower diagnostic yield for EBUS-TBNA.Conclusion: The diagnostic yield of EBUS in assessing mediastinal lymph nodes for sampling and diagnosis is 85%. This benefit is expected in the case of lesions larger than 10 mm, lesions of a malignant nature, as well as lesions in the inferior paratracheal and subcarinal stations.

Acute Pericarditis

A 27-year-old man was diagnosed with inflammatory myofibroblastic tumor, and multiple lymph node and subcutaneous metastases. After several administrations of anti-tumor therapy, he underwent mediastinal lymph node biopsy using endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) to confirm tumor relapse. Five weeks later, he complained of chest pain, then rapidly developed shock due to acute pericarditis. Although he was treated with antibiotics for anaerobic bacterial infection and cardiac drainage, mediastinal lymph node abscess and pericarditis did not improve. After the surgical procedure, his physical condition dramatically improved and he was treated with another molecularly targeted therapy. Pericarditis associated with EBUS-TBNA is extremely rare. In this case, salvage was achieved by surgical drainage of the lymph node abscess and pericarditis, and long survival was obtained with further administration of anti-tumor treatment.
