Using blood tests to screen high-risk patients for lung cancer

Feasibility Study of Lung Cancer Screening Using Cell-Free DNA Liquid Biopsy at Home in High-Risk Current and Former Smokers

NA · City of Hope Medical Center · NCT05384769

This study is testing if a blood test can help high-risk patients get screened for lung cancer more easily and encourage them to follow up with further testing if needed.

What this trial studies

This clinical trial evaluates the feasibility of using cell-free DNA liquid biopsy as a screening method for lung cancer in high-risk patients. Participants will choose between two cohorts: one undergoing a blood sample collection with the option for a low dose CT scan if results are positive, and the other receiving a low dose CT scan with an optional blood test. The study aims to assess follow-through rates for screening and compare sociodemographic factors among participants. The goal is to determine if liquid biopsy can encourage more patients to pursue further screening for lung cancer.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 50-80 with a significant smoking history and a referral for lung cancer screening.

Not a fit: Patients currently exhibiting symptoms of lung cancer or those who have had recent imaging studies may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to earlier detection of lung cancer in high-risk patients, improving treatment outcomes.

How similar studies have performed: Other studies have explored liquid biopsy for cancer detection, showing promising results, but this specific approach in a community setting is relatively novel.
