What is stereotactic radiotherapy?
Stereotactic radiotherapy (SRT) is also referred to as stereotactic body radiotherapy (SBRT) or stereotactic ablative radiotherapy (SABR). It is an advanced technique used to treat small, well-defined tumours or high-risk postoperative areas. It can be used to treat both primary and metastatic (sometimes referred to as secondary tumours).
These are tumours that have spread from other organs in the body and cancers in the brain, spine, bones, liver and lung. The technology allows a high dose of radiation to be delivered to the tumour very precisely, without compromising surrounding healthy organs due to the ability to treat with sub millimetre accuracy. Due to the larger daily doses of radiation delivered to patients with stereotactic radiotherapy, treatments can be completed within a single treatment, or multiple treatments spanning over 2-10 days. Each daily treatment usually takes no longer than 20 minutes.
Stereotactic radiation therapy by cancer type
Stereotactic radiation therapy for oligometastatic disease
Stereotactic radiation therapy can be used to treat oligometastatic disease which are secondary tumours that have spread beyond the original tumour and form within various organs. Oligometastatic disease may be treated with stereotactic radiation therapy with the aim of improving patient outcomes and controlling the disease.
Our world-class treatment technology, coupled with advanced imaging techniques, like a PET/CT scan, can be a powerful tool to clearly identify and accurately target these small tumours that might otherwise go undetected. Our expert radiation oncologists will be able to advise you if this treatment option is available and recommended for you.
