Stereotactic Radiosurgery is a non-surgical type of radiotherapy that delivers high dose radiation with extreme precision to treat small, localized tumours in the brain, with the aim of destroying the tumour and achieving permanent local control. This is usually done as a single outpatient treatment session. As no surgery is involved in SRS, the benefits include avoiding the risk of haemorrhage, infection, and anaesthesia that come from surgery.
Furthermore, there is minimal interruption of other treatments, such as chemotherapy. The results for SRS for brain metastases appear to be equivalent to the results for surgery to remove the tumour.
Volumetric modulated arc therapy [VMAT] involves the use of external radiation therapy beams being directed in a series of arcs or angles to allow for greater access to tumour. VMAT allows more difficult tumours, such as ones wrapped around other important structures, to be targeted precisely.
