Yes, as one who also had SBRT, I have been puzzled by the great variety of protocols.
I had SBRT eleven years ago at a well-known medical center with a great deal of expertise in SBRT. Even then, there was no body cast. Space OAR didn't exist at the time but is now used by the group, I was told. No endorectal balloon even then. Placement of the fiducials was through the rectum and ciprofloxacin was prescribed to minimize the chance of infection. I had SBRT every other day.
There are a lot of variables, that's for sure, but it is good to see improvements.
