Gamma Knife Radiosurgery for Brain Metastases: Do Patients Benefit from Adjuvant External-Beam Radiotherapy? An 18-Month Comparative Analysis

Abstract

Gamma knife stereotactic radiosurgery is a safe and effective treatment option for patients with cerebral metastases. It provides survival benefits and improves quality of life by achieving excellent control of the brain disease, irrespective of patients' age or number of brain tumors. The addition of XRT in younger patients with small brain metastases does not improve survival and/or control of the brain disease.
