CyberKnife® Always Precise

Clinically proven, CyberKnife® has helped thousands of people around the world.

The CyberKnife® system is one of the most accurate and precise SABR system available, delivering high doses of radiation to the prostate whilst minimising radiation of the surrounding organs including the bladder and rectum.

OVERVIEW

Common Treatment Options

Prostate Cancer is the most commonly diagnosed cancer among males in Australia and is thought to be the second most common cause of male cancer death (Cancer Australia). Treatment options typically depend on a variety of factors, including the stage and extent of disease, and include one or a combination of surgical, chemotherapy and radiotherapeutic modalities.

When indicated, radiation therapy has been delivered using conventional Linear Accelerators emitting small doses of radiation over 38-40 treatments spanning a 7-8 week treatment cycle.

By comparison, more recent Stereotactic Ablative Body Radiation (SABR) techniques deliver very high doses of radiation over far fewer treatments. However, these methods require extreme levels of accuracy and precision, particularly because the prostate gland is continually moving and in close proximity to other sensitive organs (Hamstra, D.A., et al., Continued Benefit to Rectal Separation for Prostate Radiation Therapy: Final Results of Phase III Trial. International Journal of Radiation Oncology • Biology • Physics, 2017. 97(5): p. 976-985).

Prostate cancer treatment using CyberKnife® is one of the most accurate and precise SABR system available, delivering high doses of radiation to the prostate whilst minimising radiation of the surrounding organs including the bladder and rectum.

Our 5D Clinic specialists work closely with your existing medical team to determine whether CyberKnife® treatment is right for you.

ADVANTAGES OF CYBERKNIFE®

The CyberKnife® System is clinically proven to be effective.

Prior to treatment, a number of steps are taken to allow maximum dose (and therefore greatest efficacy) and protect surrounding healthy tissue. First, a Urologist implants 4 gold seed markers into the prostate gland, providing targets on which the CyberKnife® robot can lock.

Next, a SpaceOAR gel is inserted between the prostate and rectum (see image to your right) to shield the rectum from radiation and minimise toxicity (SpaceOAR).

Treatment is then typically delivered in 3 to 5 sessions over 1-2 weeks, often with minimal side effects.
