Feasibility of Cell-Free DNA Liquid Biopsy in Screening High-Risk Patients for Lung Cancer

Recruiting now · Not applicable

Conditions studied: Lung Carcinoma

In brief

This clinical trial investigates how practical and doable (feasibility) cell-free deoxyribonucleic acid (DNA) liquid biopsy is in screening high-risk patients for lung cancer. Currently, a low dose computed tomography (CT) scan is used to screen for lung cancer, however, due to various factors, few high-risk patients are screened. Liquid biopsy utilizes technology that can detect small amounts of DNA shed by cancer cells and may be able to spot lung cancer at an earlier stage. If a positive result comes back from the liquid biopsy, a patient may be more willing to get a low dose CT (LDCT) scan, possibly confirming the biopsy's findings and thus leading to more early lung cancer detection.
