Precision brain radiation study aims to spare thinking skills in cancer patients

This study tests whether a precise form of radiation called stereotactic radiosurgery (SRS) can control lung cancer that has spread to the brain while better preserving patients' memory and thinking abilities. It compares SRS, which targets only the tumors, to standard whole-brain radiation that affects the entire brain and often causes cognitive side effects. The trial involves 55 patients with small cell lung cancer that has spread to the brain, measuring how their brain function changes over time with this more focused treatment approach.
