Trial of ctDNA of Guidance to Determine PostOperative Radiation Therapy

A personalized, tumor-informed circulating tumor DNA (ctDNA) test that analyzes blood samples to detect minimal residual disease (MRD) and guide postoperative treatment decisions for patients with Stage II-III non-small cell lung cancer (NSCLC) following surgical resection. The test results will help determine whether patients should receive postoperative radiation therapy (PORT) and/or systemic therapy adjustments.
