SpaceOAR® System – Rectal Protection for Prostate Cancer Radiation Therapy Patients

Southeast Nebraska Cancer Center is now offering a new tool that is proven to protect prostate cancer patients from the negative effects of radiation therapy. We are the first in Nebraska to introduce this to our patients.  Read more about this exciting announcement from the Journal Star.

Because of the close proximity of the prostate to the rectum, prostate radiation therapy typically results in some radiation hitting the rectum, which can sometimes cause side effects, such as pain during bowel movements, rectal urgency, bleeding or loose stools during or after radiation treatment. That’s why the rectum is called the Organ At Risk (OAR) during prostate radiation therapy.

SpaceOAR System reduces rectal injury in men receiving prostate cancer radiation therapy by acting as a spacer – pushing the rectum away from the prostate and out of the high dose radiation region.

The hydrogel spacer is injected during a minimally invasive procedure, and — once in place — patients typically can’t feel it. The hydrogel is safe and similar to other products used in brain surgery, cardiology and ophthalmology. It remains in place for 3 months during radiation treatment, and is then absorbed and leaves the body in the patient’s urine — leaving nothing behind.

SpaceOAR System has been has been clinically proven and studied in a US Clinical Trial and is FDA cleared for sale in the United States.
