Stereotactic radiosurgery for brain and spine metastases.

Metastases to the brain and spine are common and difficult to treat. Stereotactic radiosurgery (SRS) is a non-invasive treatment option for some individuals, and may obviate the need for open surgery and/or whole brain radiotherapy. Over the past decade there has been an increased number of patients undergoing SRS for the treatment of metastatic disease, and multiple published studies show favourable results in terms of local disease control.
