Read our Lung Cancer research guide →This research study is investigating whether special blood tests can help doctors predict which patients are at risk for lung cancer returning after surgery. Researchers will collect blood samples before your surgery, during the surgery, and then regularly after surgery over time. By studying these blood samples, the team hopes to develop a better way to monitor patients and catch any signs of cancer coming back early.
After surgery for early-stage lung cancer, doctors don't currently have a reliable way to predict who will have their cancer return. This study aims to fill that gap by developing a blood test that can detect tiny traces of cancer that might remain in the body, which could help doctors give you better follow-up care and treatment decisions.

You will donate a blood sample (about 20 milliliters, or roughly 4 teaspoons) before your surgery and then give additional blood samples regularly after surgery — roughly every 3 to 6 months. The study team will also use tissue from your tumor that was removed during surgery. Over time, researchers will track whether the blood tests show any signs of cancer returning, and you'll continue follow-up visits as part of normal cancer care.
