In addition to our standard external beam radiation therapy service, Genesis CancerCare Queensland also performs several specialised procedures with the assistance of other medical specialists. These procedures are used to manage specific medical conditions that would benefit from a highly personalised treatment approach.
Specialised procedures include:
- BrainLab Stereotactic Radiation Therapy & Radiosurgery.
BrainLab is an advanced linac based system used to treat small brain tumours or neurological lesions that may be considered inoperable due to the sensitivity of the surrounding structures. This procedure usually requires the combined expertise of a neurosurgeon and a radiation oncologist to map the location of a lesion before treatment is delivered.
- Low dose rate brachytherapy
Low dose rate brachytherapy is an internal radiation treatment used to treat men with localised low to intermediate risk prostate cancer. This procedure involves the placement of radioactive seeds into the prostate by a urologist under the guidance of a radiation oncologist.
- High dose rate brachytherapy
High dose rate brachytherapy is an internal radiation treatment used to manage localised aggressive prostate or gynaecological malignancies. Depending on treatment site, a urologist may be required to surgically place applicators for radiation delivery. This treatment may be combined with external beam radiation therapy to administer a curative radiation dose.
- Fiducial marker placement
Fiducial markers are small inert gold seeds that are inserted into the body to provide a point of reference for identifying a treatment area on an X-ray image.
These markers may be inserted into the prostate to improve the accuracy of treatment when using Intensity Modulated Radiation Therapy (IMRT) or Volumetric Modulated Arc Therapy (VMAT / RapidArc).
Their use enhances tumour targeting resulting in reduced radiation exposure to surrounding organs and tissues.The insertion of fiducial markers for prostate radiation therapy is performed by a urologist.
- SpaceOAR injection (spacing organs at risk)
SpaceOAR is a liquid that is injected between the prostate and rectum under ultrasound guidance. Once injected, the liquid solidifies within seconds into a hydrogel that pushes the rectum away from the prostate.
This procedure reduces radiation exposure to the rectum and related side effects during Intensity Modulated Radiation Therapy (IMRT) or Volumetric Modulated Arc Therapy (VMAT) for prostate cancer.
The hydrogel maintains space throughout treatment and then liquefies, allowing it to be absorbed and cleared from the body.The injection of SpaceOAR liquid for prostate radiation therapy is performed by a urologist.
