Circulating Tumor Deoxyribonucleic Acid Testing for the Guided Treatment of Stage II-III Non-small Cell Lung Cancer, MRD-PORT Trial

Trial Status: active

This clinical trial studies whether circulating tumor deoxyribonucleic acid (ctDNA) testing can be used to guide the treatment of stage II-II non-small cell lung cancer (NSCLC). Deoxyribonucleic acid (DNA) is the material that carries all the information about how a living thing will work or function. Many types of tumors tend to lose cells or release different types of cellular products including their DNA, which is referred to as ctDNA, into the bloodstream before changes can be seen on scans. Health care providers can measure the level of ctDNA in blood or other bodily fluids to determine which patients are at higher risk for disease progression or relapse. The ctDNA levels can be drawn after the patient undergoes surgery to remove the tumor (postoperative) to see if any ctDNA remains. The postoperative ctDNA levels can then be used by doctors to help decide whether to start, stop, or change treatment. It can also be used to help doctors decide whether radiation therapy should be used to kill tumor cells that may have been left behind after surgery. This may be an effective way to guide the treatment of stage II-III NSCLC.
