One-shot radiation blast aims to crush liver tumors

This study tests whether a single, extremely high dose of radiation delivered by a special MRI-guided machine (MR-Linac) can better control liver tumors that have spread from other cancers compared to the usual high dose. About 114 adults with up to three liver metastases from specific cancers (like colorectal or lung) will be randomly assigned to receive either the experimental ultra-high dose or standard high dose radiation. The goal is to see if the higher dose improves local tumor control and quality of life while keeping side effects low.
