Metastases are the most common brain tumors. After surgery, stereotactic radiotherapy (SRT) of the resection cavity is the standard of care. Data from two randomized trials indicate that SRT to the surgical bed is an effective treatment in reducing local failure as compared with observation, while reducing the risk of cognitive deterioration and maintaining quality of life as compared with whole brain radiation therapy. Local control appears higher after hypofractionated SRT compared to single-fraction SRT. Several questions such as target volumes, the optimal regimen in particular for large tumor bed, strategies to reduce the risk of lepto-meningeal recurrence, and the treatment sequence still need to be answered.
