Diagnosis and Staging of Lung Cancer Using Minimally Invasive Technique With Ultrasound Guidance

Introduction: Endobronchial Ultrasound (EBUS) is a procedure that is performed via flexible
bronchoscopy under moderate sedation for visualization of lymph nodes in the chest and
biopsy under real-time guidance for the staging of lung cancer or evaluation of enlarged
lymph nodes. In addition, lung lesions or masses can be visualized and biopsied in the same
sitting. The use of EBUS has enhanced the safety and diagnostic yield of flexible
bronchoscopy.

Aim: The data of patients with suspected lung cancer or undiagnosed lymph node enlargement
in whom bronchoscopy with EBUS guidance is clinically indicated will be collected
prospectively.

Results from EBUS are considered positive if a specific diagnosis is obtained ( eg
malignancy) or if lymphocytes are present in the lymph node biopsy, indicating accurate
sampling of lymph node. In patients with non-diagnostic EBUS, the results from other
procedures will be compared for analysis.
