What is SpaceOAR® hydrogel?
SpaceOAR hydrogel is an absorbable hydrogel that temporarily creates space between the prostate and the rectum, protecting the rectum from radiation exposure during prostate radiation therapy.
Why should I have SpaceOAR hydrogel?
The goal of radiation therapy to treat prostate cancer is to maximize the radiation dose to the prostate to kill the cancer cells while avoiding radiating surrounding normal tissue. Rectal injury can occur because the rectum sits next to the prostate and can accidentally receive high radiation doses and damage to healthy tissue can cause side effects. The “OAR” in SpaceOAR stands for “Organ At Risk”, and with Radiation Therapy to the prostate, this organ is the rectum.
How will SpaceOAR hydrogel help me?
By acting as a spacer, the hydrogel pushes the rectum a ½ inch away from the prostate so damage to the rectum is reduced or even eliminated. With SpaceOAR hydrogel in place, your doctor can enhance your radiation treatment to better target your cancer while preserving healthy tissue to help ensure that your rectal, urinary and sexual quality of life will be maintained.
What is it made of and is it safe?
SpaceOAR hydrogel is made up of two liquids that when combined form a soft gel material that is mostly made of water. Because of the water content it is called a hydrogel. It can be safely used in the body without causing injury or a reaction. The material that the SpaceOAR hydrogel is made from has been used in other implants such as surgical sealants used in the eye, brain and spine.
