Using cell-free DNA to detect recurrence in early non-small cell lung cancer

Prospective Feasibility Study of Cell Free Circulating Tumor DNA for the Diagnosis and Treatment Monitoring in Early-stage Non-small Cell Lung Cancer

Observational Samsung Medical Center · NCT03791034

This study is testing if checking for tumor DNA in the blood can help find out sooner if non-small cell lung cancer comes back after surgery.

What this trial studies

This observational study aims to evaluate the role of circulating cell-free tumor DNA (cfDNA) in detecting recurrence of non-small cell lung cancer (NSCLC) after complete surgical resection. By analyzing cfDNA levels in patients who have undergone curative surgery, the study seeks to determine if cfDNA can provide earlier indications of cancer recurrence compared to traditional follow-up methods. Additionally, the genomic signature of cfDNA will be examined to explore its relationship with clinical outcomes in NSCLC patients.

Who should consider this trial

Good fit: Ideal candidates include patients with early-stage non-small cell lung cancer (clinical stage I - IIIA) who have undergone curative resection.

Not a fit: Patients with recurrent lung cancer or those who have received chemotherapy or radiotherapy for non-small cell lung cancer will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to earlier detection of cancer recurrence, potentially improving patient outcomes.

How similar studies have performed: Previous studies have indicated that cfDNA can detect cancer recurrence earlier than conventional methods, suggesting a promising avenue for this approach.
