I am wondering if anyone has information regarding any loved ones surviving PC with this procedure. My brother has PC. It is wrapped around a blood vessel (and/or artery?) He is in a clinical trial ..using a trial drug...and chemo and radiation. Seems there is always something coming up to delay the treatments... I am starting to wonder if he is being kept in this trial....for their own good.....and we should research other options. I asked his doctors about the Cyber Knife, and they say it is used for brain tumors...not PC...however, I know this is not true!! Anyone recommend getting the heck out of the trial and giving the Cyber Knife a try???
