Background: The diagnostic and staging approach for the mediastinal lymphadenopathies, with or whithout pulmonary lesions endoscopically visible, is based on transbronchial needle aspiration (TBNA) during fiberoptic bronchoscopy and on mediastinoscopy. One important factor impacting on TBNA sensitivity is the rapid on site cytological examination (ROSE).
Aim: The aim of this study was to evaluate the economic impact of TBNA and TBNA + ROSE, in the diagnosis of these lesions.
Patients And Methods: 120 patients, affected by mediastinal lymphadenopathies suspected for lung cancer, underwent TBNA during fiberoptic bronchoscopy: 60 patients without ROSE (group A) and other 60 with ROSE (group B). Whenever needle aspirations failed to provide diagnosis, the patient underwent mediastinoscopy. The economic impact of the diagnostic process was performed.
Results: In group A, 39 patients (65%) obtained a diagnosis with TBNA while 21 patients (35%) required mediastinoscopy. In group B, 48 patients (80%) obtained a diagnosis with TBNA + ROSE, while 12 patients (20%) required mediastinoscopy. With regards to the costs of the procedures performed in the diagnostic process, the use of TBNA with ROSE as first diagnostic approach has saved a considerable amount of euros (19,413) compared to the use of TBNA without ROSE and the combined procedure increased (p < 0.02; chi square test) the sensitivity of TBNA by 15%.
Conclusions: ROSE significantly impacts on the diagnostic yield, as well as on the overall management costs of patients with mediastinal lymphadenopathy, suspected for lung cancer.

Diagnostic Value of Endobronchial Ultrasound-Guided Intranodal Forceps Biopsies Combined with Rapid On-Site Evaluation for Mediastinal/Hilar Lymph Node Disease.

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.

Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a critical method for diagnosing lung cancer. While EBUS-TBNA is commonly performed under conscious sedation, the potential benefits of conducting the procedure under general anesthesia and incorporating rapid on-site evaluation (ROSE) to enhance diagnostic yield remain uncertain. This study aims to investigate the impact of anesthesia methods and ROSE on the diagnostic efficacy of EBUS-TBNA for lung cancer.

Introduction: The effective deployment of rapid on-site cytologic evaluation (ROSE) requires the availability of a cytologist/pathologist. Several studies investigated the capability of trained pulmonologists to assess the adequacy and validity of transbronchial needle aspiration (TBNA) samples. This study aimed to determine the validity and adequacy of ROSE by pulmonologists (P-ROSE).

Biomedical scientists (BMS) can report sample adequacy during EBUS TBNA using rapid on-site evaluation (ROSE). Despite being able to report exfoliative samples such as pleural fluid cytology and bronchial washings, they are usually not permitted to offer a preliminary diagnostic impression of EBUS TBNA samples. Experienced biomedical scientists can provide a reliable diagnostic impression during ROSE for EBUS samples, with sensitivity and specificity comparable to cytopathologist reporting.

Article Synopsis
- Lung cancer is the top cause of cancer deaths globally, and screening high-risk individuals with low-dose CT scans can help reduce mortality.
- This meta-analysis investigated the effectiveness of rapid on-site evaluation (ROSE) during bronchoscopy for improving diagnostic accuracy in lung cancer detection using data from 32 studies with over 8,200 lung lesions.
- The findings showed that ROSE has high sensitivity (91.8%) and specificity (94.9%) for lung cancer diagnosis, particularly in patients who had low-dose CT scans, and it is also effective for staging lung cancer with endobronchial ultrasound-guided needle aspiration.
