Stereotactic ablative radiotherapy (SABR) is a specialised type of radiotherapy. It is sometimes called stereotactic body radiotherapy.
SABR uses scans and specialist equipment to precisely target radiotherapy to treat certain cancers accurately. It’s only suitable for some people, usually those with smaller cancers. SABR is usually given over a shorter time than standard radiotherapy.
This treatment is currently not widely available in the UK. You may be referred to a specialist hospital if your doctor thinks it’s a suitable treatment for you. We have more information about what you can do if a treatment isn't available.
SABR is known by a number of different names and this can be confusing. The names may relate to the area of the body being treated, the type of machinery being used or the length of treatment. They include:
- stereotactic body radiotherapy (SBRT)
- stereotactic radiosurgery (SRS)
- extracranial radiosurgery
- extracranial radiotherapy
- stereotactic radiation therapy (SRT)
- CyberKnife™ (a machine used to give SABR).
The most commonly used brand names are CyberKnife™, Varian® and Elekta®.
We use the term stereotactic ablative radiotherapy, or SABR for short.
