Stereotactic Radiosurgery

Quick, Painless and Bloodless curative treatment for Prostate Cancer

What is Prostate Stereotactic Radiosurgery?

Stereotactic Radiosurgery is an ultra-targeted, non-invasive treatment that delivers high doses of radiation to a target, eliminating the cancer cells within.

It is a recognized curative treatment option[1] for localized prostate cancer and is also known as Prostate Stereotactic Body Radiotherapy (SBRT). Please see here for some technical details.

Understanding the difference between Surgery and Radiosurgery

Surgery involves physically cutting through tissue and bone to reach the tumor so as to remove it from the body.

Radiosurgery does not involve any cutting at all. The name was given because after destroying the tumor with high doses of focused radiation, the body automatically removes the dead cells, and the cure rate is as if surgery was done 

It is completely painless, bloodless and is done as an outpatient procedure.

Patient does not need to undergo open surgery and does not suffer from operation risks

WIth a MRI to target the prostate (red) precisely, smaller treatment margins (pink line) can be used resulting in much lower exposure of the bladder (brown) and rectum (light green) to the treatment dose

Radiation is delivered rapidly in a circular motion under direct supervision by a radiation oncologist, with tumour killing doses (red area) delivered to the prostate, and mostly low to moderate doses (blue to green)  going to limited areas of the rectum and bladder

SpaceOAR Hydrogel spacer is now available to our patients in Singapore

When treating prostate cancer patients with radiation therapy, the goal is to destroy the cancer cells while avoiding damage to surrounding healthy tissue.

How Does It Work?

SpaceOAR Hydrogel is injected into the space between the rectum and the prostate. This gel increases the distance between the 2 organs, vastly reducing high dose radiation to the rectum. 

What Is It Made Of?

SpaceOAR Hydrogel is made from a soft gel-like synthetic material that mostly consists of water and is safe to use in the body. Following treatment, the SpaceOAR Hydrogel liquefies and is naturally absorbed and excreted by the kidneys within six months.

What Does It Do?

SpaceOAR Hydrogel is clinically shown to minimize urinary, sexual, bowel side effects and protect quality of life for prostate cancer patients undergoing radiation therapy.

Benefits of this procedure:

  • It is minimally-invasive

  • Only requires local anesthesia

  • No hospital stay is required

  • Once done, patients can return home to their normal activities for the day!

  • Eligible for Full Insurance Coverage

The Role of the Prostate Oncologist

An oncologist is a cancer doctor who can give an overall assessment, deliver treatment for and coordinate care of a particular cancer. He/she may be trained in treating cancer with drugs, radiation therapy or both.

Further, it is ideal to be seen early by an oncologist who is a subspecialist e.g. further specialised in treating prostate cancer. That way, a holistic, comprehensive and individualised plan can be formulated.

AARO doctors trained as clinical oncologists, having received training in both drug and radiation treatment for cancer. The group offers subspecialty expertise and a balanced, evidence-based treatment philosophy.

No matter which stage the patient is at his prostate cancer journey – right after diagnosis, seeking 2nd opinion or viable treatment alternatives – we are able to advise and provide suitable treatment.
