About SABR

Stereotactic Ablative Radiation Therapy (SABR) is a short course, high dose of radiation therapy and may be an option for men with prostate cancer. SABR offers fewer treatment sessions than conformal radiation therapy, minimal toxicity, precision targeting, and potentially improved quality of life.

More on SABR

  • It is a non-surgical treatment option 
  • Delivered in an outpatient setting, with no need for hospital stays
  • Usually completed in five sessions1
  • Delivered using advanced imaging techniques that allow real-time precision tracking of the tumour, minimising radiation to surrounding healthy tissue.2,3

What is SABR?

SABR (also known as  Stereotactic Body Radiotherapy or SBRT) delivers radiation with exceptional precision, enabling higher doses of radiation therapy to target the prostate. This treatment enables suitable patients with prostate cancer to be given more radiation to destroy cancer cells in fewer treatment sessions (compared to other types of radiation therapy).1,3 Usually prostate SABR is delivered over 5 treatments compared to 4-8 weeks of radiotherapy. Because SABR can be so precise, the treatment area may be smaller than conventional radiation treatment and most people have very few side effects.2  

Who is SABR suitable for?

Your doctor is the best person to ask if SABR is appropriate for you. They will consider factors such as how active the cancer is, where it is located, the size of the prostate, any previous treatments such as a transurethral resection of the prostate, and your overall health.
