For the past 10 years, injectable gel spacers have been used to create a small protective gap between rectal tissue and the prostate during treatment. Recently, Penn Medicine Princeton Medical Center radiation oncologists have begun using a new biodegradable balloon implant system that offers more precise placement than gel and a higher level of protection from treatment side effects.
The four-centimeter balloon is positioned between the prostate and rectum and filled with a saline solution. The location of the implant is then confirmed using a CAT scan about a week later. The balloon stays in position for three months and is safely absorbed by the body after six months.
“By protecting the rectum and surrounding area with the balloon implant, the likelihood of side effects to healthy tissue, including rectal bleeding and ulcers, erectile dysfunction, urgency, and bladder irritation are dramatically reduced. The implant is an exciting evolution in treatment for prostate cancer,” says Edward M. Soffen, MD, a board certified radiation oncologist and member of the Medical Staff of Penn Medicine Princeton Health. Dr. Soffen was a principal investigator in a clinical study that examined the effectiveness of the balloon implant.
