I searched this NG about SBRT, and it returns nothing. Googling it
returns quite a few pages, and it seemed that SBRT is now being used to
treat PCa. Has anyone here done an in-depth research with respect to
cure, side effects, and comparative results to other treatments?
Previously, SBRT have been used for lung and liver cancer treatments.
Thanks.

By lack of response in several days, no one here has heard or know
anything about this therapy?

Stereotactic Beam Radiation Therapy - my understanding is a next
generation IMRT with live imaging and beam adjustment during radiation,
and higher dose, does reducing the number of sessions from 40-plus to
about five.

I had also never heard of it and so didn't respond. I looked it
up and see that it is a technique that was developed for brain
tumors that requires very precise imaging and very precise
control over both the rigidity of the patient and the control over
the beams. Apparently, this was easier to do on the head
then on the rest of the body and only recently have techniques
evolved to where it can be used elsewhere.

If the main advantage is a reduction in sessions, then it seems
to me that patients might want to wait awhile until the technique
is more developed. If the main advantage is better cancer
control - well, that's a different story.

If you find out more, post it for us.

Commander,

To the best of my knowledge, none here had SBRT as a tx.

AFAIK, the cutting edge for PCa RT these days is Image Guided RT -
basically a combo of IMRT and CT Scan.

Google it.
