Patients who were treated with radio-surgery followed by whole-brain radiation performed worse three months later on tests involving cognitive abilities.

During the study, patients were assigned to either radiosurgery followed by whole-brain radiation or radiosurgery alone. The research comprised of 213 patients, who had one to three small tumors or metastases in the brain. Patients who were treated with both approaches performed significantly worse three months later on tests involving cognitive abilities. The median overall survival was 7.5 months for those receiving both treatments and 10.7 months for those receiving radiosurgery alone.
The study was presented at the annual meeting of the American Society of Clinical Oncology on May 31, 2015.
