Comparing navigation techniques for diagnosing lung lesions

Multicenter, Open-label, Prospective Randomized Controlled Trial of Radial Endobronchial Ultrasonography and Virtual Bronchoscopy Navigation for the Peripheral Pulmonary Lesions

NA · Central TB Research Institute · NCT05739695

This study is testing which of three different methods for guiding lung examinations works best for diagnosing lung problems like cancer, tuberculosis, and pneumonia in patients with newly found lung lesions.

What this trial studies

This clinical trial aims to compare three different navigation techniques used in bronchoscopic investigations for peripheral pulmonary lesions: virtual bronchoscopy (VBN), radial endobronchial ultrasound (EBUS), and a combination of both. Approximately 300 patients with newly diagnosed, unverified peripheral pulmonary lesions will be enrolled across nine centers in Russia. Participants will be randomly assigned to one of the three navigation technique groups, and the study will analyze the diagnostic efficacy and safety of each method. The goal is to determine which technique provides the best outcomes for early detection of lung cancer, tuberculosis, and pneumonia.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with newly diagnosed solitary or multiple peripheral pulmonary lesions sized between 5 to 40 mm.

Not a fit: Patients unable to undergo navigation bronchoscopy or those with a history of malignant disease in the last 36 months may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the accuracy and safety of diagnosing lung conditions, leading to earlier treatment for patients.

How similar studies have performed: Other studies have explored similar navigation techniques, but this specific comparison of VBN and radial EBUS is relatively novel.
