Whole-brain radiation therapy (WBRT) was frequently used to treat brain metastases in the past. Stereotactic radiosurgery (SRS) is now generally preferred to WBRT for patients with limited brain metastases. SRS can also be used to treat extensive brain metastases (>10–15 metastases), and clinical trials are currently comparing WBRT with SRS for extensive disease. SRS may allow for an increased risk of radiation necrosis or leptomeningeal disease dissemination after treatment. Preoperative SRS and multifraction radiotherapy decrease the risk of these side effects and may soon become standard of care. Combining SRS with immune checkpoint inhibitors may improve patient outcomes.
