Tall Allen - how would you decide between HDR Monotherapy and SBRT? Also did you recommend Dr Freeman in Tampa for SBRT to another board member? Seem to remember seeing that but can’t find the thread - thanks MJ
Check out posts from 19tarpon47. Just put "19tarpon47" and "Freeman" in the search bar.
It was a very tough decision for me, especially because I had the pioneering practitioners of each therapy (King and Demanes) within a 10 minute drive from home. I think both are excellent, and had a hard time deciding between them. They were designed to be radiobiologically identical. One places the highly radioactive source within the prostate and the X-rays emit outwards in all directions. The other starts from a large number of outside points and only reach a cancer-killing effect at the points in which the beams converge in the prostate. Both have very low toxicity outside of the prostate - the dose/volume histograms, which show the amount of radiation absorbed by organs near the prostate are pretty much identical. Both are extremely hypofractionated - which we now know has greater prostate cancer killing power and lower healthy cell killing power (because of the reduced total dose) than conventional fractionation. They both have a very low amount of ED - 70-80% of men retain potency. They both have near certain probability of reducing or eliminating ejaculate.
HDR-BT has the longer track record, it has been used as a monotherapy since 1995. SBRT has been used for prostate cancer since 2003.
HDRBT involved 2 overnight hospital stays (they've since reduced it so the two treatments can be done without an overnight stay). It also involved anesthesia and is intrusive. SBRT took only five 5-10 minute treatments. Dr King does not require any bowel prep or special diets because he uses a very fast machine. (Some machines take 45 minutes to an hour for each treatment and involve bowel prep and low-gas diets). SBRT also costs a lot less than HDR-BT, so if you pay a co-pay, that is a consideration. In the end, I chose SBRT because it was easier and cheaper.
I have had some fairly mild irritative side effects along the way, but they were transient, as is most often the case. Currently, I have no side effects, no ED whatever, but also no ejaculate. I am very pleased with my choice. I'm pretty sure I would have been equally pleased with HDR-BT.
