Consulted by video with the doctor who is supposed to install my SpaceOAR in preparation for my IMRT. His first words were "we don't use SpaceOAR gel anymore. We use Barrigel." He explains it has fewer side effects but the same radiation absorption characteristics. Here is what "UroToday" says:
"Barrigel, which allows more time to create symmetrical spacing and has a shorter learning curve for trainees. Barrigel also has a lower risk of rectal wall invasion and is more comfortable for patients. The Barrigel trial showed a significant reduction in toxicity in the first three months compared to the SpaceOAR trial, which showed toxicity reduction after 18 months. They emphasize the importance of symmetry in spacing for optimal radiation therapy outcomes. The take-home message is that Barrigel provides greater control and safety in rectal spacing during radiation therapy for prostate cancer patients."
The procedure will be scheduled in April. IMRT is scheduled for May. The doctor explained the procedure needs no prep (maybe an enema of the lower bowel) and he anesthetizes the insertion region while administering laughing gas. Takes about 30 minutes and I can drive myself home. I liked the doctor, had detailed answers for all of my questions. The gel lasts approximately 6 mos. and the IMRT should commence within 2-3 weeks of procedure. Statistically, almost 10% of patients develop significant bowel irritation over several years from EBRT. He said sometimes effects don't show up for up to 8 years. A spacer gel cuts the occurrence to just over 2%. For me that's a significant reduction and well worth any risks from the procedure, so I'm signing up.
BTW, finished my first week of Orgovyx. No manifest SEs to report, but I feel different--not for the good.
