Blood test guides Life-Saving treatment to stop Cancer's return

This study aims to see if a personalized treatment plan can prevent esophageal cancer from coming back after surgery. It will enroll 172 patients who have had their cancer surgically removed but still have tiny amounts of cancer DNA in their blood, putting them at high risk for recurrence. These patients will be randomly assigned to either receive a combination of chemotherapy and immunotherapy drugs or to be closely monitored without additional drug treatment, to see which approach better keeps the cancer away.
