Stereotactic Radiosurgery (SRS) and Stereotactic Body Radiotherapy (SBRT) Programme

Stereotactic Radiosurgery (SRS) and Stereotactic Body Radiotherapy (SBRT) are the most precise and effective forms of radiation therapy. It combines the principles of three-dimensional target localisation (also called stereotaxy) with multiple intersecting radiation beams to precisely treat tumours in difficult or hard to reach areas with common techniques. This technique is minimal or non-invasive. However, it allows for therapeutic doses necessary to destroy tumours with minimal risk to surrounding sensitive or critical structures compared to other more conventional techniques.This treatment is also known as Cranial (in the skull i.e. brain) and Extracranial (outside the skull) Stereotactic Radiosurgery.

This form of radiotherapy treatment uses technically advanced equipment to both position the patient and provide an extremely precise reference to the location of the treatment area. This, as with the other techniques mentioned earlier, allows the team to plan treatment to deliver the highest suitable dose to the treatment area while sparing normal tissue, sometimes in as little as one treatment session (fraction).

In some patients such as those having lung treatment the IGRT mentioned above will be used in conjunction with Stereotactic Radiosurgery to deliver precision treatment. This is a much specialised form of treatment only suitable for patients whose tumour fall into specific categories where the area for treatment is small and well defined.

Some patients with benign brain conditions may also be suitable for stereotactic Radiosurgery. If your Radiation Oncologist thinks that you might be suitable for this kind of treatment he/she will advise you of this as one of your treatment options.

The consultants at Beacon Hospital are actively involved at international meetings on SRS and SBRT.
