Comparing two methods for obtaining lung cancer tissue samples

A Multicenter Randomized Trial of EBUS-TBNA Versus Transbronchial Mediastinal Cryobiopsy for Adequacy of Next Generation Sequencing

Phase 4 Interventional Vanderbilt-Ingram Cancer Center · NCT06105801

What this trial studies

This multi-center clinical trial evaluates the effectiveness of transbronchial mediastinal cryobiopsy compared to endobronchial ultrasound with transbronchial needle aspiration (EBUS-TBNA) in acquiring sufficient tissue for molecular analysis in lung cancer patients. Participants will be randomized to receive either the standard EBUS-TBNA or the cryobiopsy method during their bronchoscopic biopsy procedure. The study aims to determine which method yields a higher proportion of adequate samples for next-generation sequencing and assesses safety endpoints related to the procedures.

Who should consider this trial

Good fit: Ideal candidates are adults with suspected malignant lung lesions that are amenable to biopsy and have shown malignant cells on rapid on-site cytological evaluation.

Not a fit: Patients who are under 18 years old, pregnant, or whose lesions are deemed unsafe for biopsy will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy of lung cancer diagnoses and treatment planning through improved tissue sampling techniques.

How similar studies have performed: Other studies have explored similar biopsy techniques, but this specific comparison of cryobiopsy and EBUS-TBNA for next-generation sequencing adequacy is novel.
