Radiation 'Reset' trial aims to Re-Sensitize tumors to treatment

This study is testing if a very low dose of radiation can make tumors sensitive again to immunotherapy drugs in patients with advanced esophageal cancer that has stopped responding to standard treatment. About 32 adults who have progressed after first-line chemo-immunotherapy will receive a single, low-dose radiation treatment to all visible tumors, then continue their immunotherapy. Researchers will track if this approach safely controls the cancer longer and if tumors shrink.
