Precision radiation may buy more time for patients with spreading cancer

This study tests whether a precise, high-dose radiation technique called SABR works better than standard palliative radiation for people whose cancer has spread to a few new spots while on treatment. About 194 adults with solid tumors (excluding lymphoma or myeloma) and up to 5 growing lesions will be randomly assigned to receive either SABR or standard radiation. Neither the patient nor their doctor will know which treatment they get. The goal is to see if SABR can delay the need for a new systemic therapy and improve quality of life.
