Trial Outcomes & Findings for Robotic Versus Electromagnetic Bronchoscopy for Pulmonary LesIon AssessmeNT: (the RELIANT Trial) (NCT NCT05705544)

NCT ID: NCT05705544

Last Updated: 2025-04-24

Results Overview

Diagnostic yield is defined as the proportion of procedures that results in acquisition of lesional tissue. Lesional tissue is defined by the presence of histopathological findings that readily explain the presence of a pulmonary lesion. The following common histopathological findings are pre-specified as lesional: i. Malignant ii. "Specific benign" findings accounting for the presence of a PPL 1. organizing pneumonia, or 2. frank purulence/robust neutrophilic inflammation, or 3. granulomatous inflammation, or 4. other specific benign finding findings such as hamartoma, amyloidoma or other uncommon causes of PPLs with distinctive pathological patterns.
