Endobronchial Ultrasound vs Mediastinoscopy in NSCLC

Non-small Cell Lung Cancer Clinical Trial

Official title: Prospective Controlled Trial of Mediastinoscopy Compared With Endobronchial Ultrasound Guided Transbronchial Needle Aspiration for Assessment of the Mediastinum in Lung Cancer.

Status Completed

Clinical Trial Summary

Proper staging of Lung cancer is of paramount concern when determining a treatment regime. Currently the assessment of surgical candidacy is performed with the staging process, mainly the mediastinoscopy. A mediastinoscopy has the ability to access samples of the paratracheal lymph node stations (Levels 2R, 2L, 3, 4R, 4L), as well as the anterior subcarinal lymph node station (Level 7). In comparison, the EBUS-TBNA technique is a real-time procedure that has the potential to access the same paratracheal and subcarinal lymph node stations associated with the mediastinoscopy, but also extending out to the hilar lymph nodes (Levels 10 and 11). Because of the possibility of extended sampling range and a reduction in procedural invasiveness, EBUS-TBNA may represent a more efficient patient centered alternative to mediastinoscopy in the staging of lung cancer patients. Additionally, patients who are have lymph nodes in the N2 region frequently undergo chemotherapy and/or radiotherapy prior to surgery. Assessment of the lymph nodes after chemo/radiation is done using CT scans, as re-mediastinoscopy is a technically difficult procedure. These patients may benefit from EBUS-TBNA.
