Brain metastases (BMs) are diagnosed in 10%–40% of all patients with cancer, and the incidence continues to increase along with the number of long-term survivors. When BMs occur, they are often associated with a myriad of symptoms, including neurologic dysfunction and functional decline; both are difficult to manage and can be distressing for patients and their caregivers. Although clinically significant findings have not kept up with the rapid pace of scientific breakthroughs in understanding the mechanisms of BMs, novel approaches that affect the prognosis of patients with BMs have been introduced in clinical practice.
