SpaceOAR hydrogel is an option for men who undergo radiation treatment for prostate cancer. It acts as a spacer providing space between the rectum and the prostate, making it much less likely that the rectum is exposed to radiation. It is injected into place prior to the start of radiation treatment. Patients may be awake or asleep under general anesthesia for the procedure. SpaceOAR hydrogel is minimally invasive, remains stable during radiation therapy and then is gradually absorbed by the body after radiation therapy has been completed.

What is SpaceOAR Hydrogel?

SpaceOAR Hydrogel is an absorbable gel material that creates a temporary space between the prostate and the rectum, potentially reducing radiation dose to the rectum during prostate cancer radiation. It separates the prostate and rectum and is naturally absorbed by the body in about six months. More than 50,000 patients worldwide have been successfully treated with SpaceOAR Hydrogel.

For what condition is SpaceOAR Hydrogel used?

SpaceOAR Hydrogel is an option for men preparing to undergo radiation treatment for prostate cancer. It is designed to reduce the radiation dose delivered to the rectum and help maintain rectal function.

Why is SpaceOAR Hydrogel important for patients?

When treating prostate cancer patients with radiation therapy, the goal is to kill the cancer cells while avoiding damage to surrounding healthy tissue. The prostate is next to the rectum and naturally separated by a small space. Due to the proximity, prostate radiation therapy can unintentionally cause damage to the rectum, which can lead to issues with bowel function. SpaceOAR Hydrogel is a gel spacer that temporarily moves the rectal wall farther away from the prostate. By separating the prostate from the rectum, the radiation dose delivered to the rectum is reduced, which may lessen damage to the rectum.
Clinical data demonstrated the benefits of SpaceOAR Hydrogel, including a reduction of rectal injury resulting in maintained bowel function and a higher likelihood to maintain urinary and sexual function.
