Alan Katz came through again with a 10-year SBRT update. This one is only on his low risk patients (intermediate and high risk update will be presented at next year's ASTRO meeting). This makes it the longest follow-up study on any kind of external beam radiation for PC. It ties with the MSK study of IMRT, but with much bigger sample size.

For the low risk men, SBRT did better than IMRT in oncological control, and the same on side effects.

I can't imagine any insurance company now saying that longer follow-up is needed.

Yeah, but some will still say more follow-up is needed.

SBRT does appear the way to go.

It's one of the great mysteries to me -- why insurance would not prefer SBRT. It is half the cost, works as good or better, and the subsequent care is as low as IMRT. I can readily understand why an RO in private practice would not prefer it - it cuts his income in half.

Can SBRT be used as salvage therapy after surgery?

Frack me-

Experimentally, yes. My RO, Chris King, is working on a clinical trial of salvage SBRT after Prostatectomy. He is convinced that salvage radiation often requires a higher biologically effective dose (BED) than is normally given (he routinely delivers 72 Gy), and SBRT is a way to kick up the BED. I know his biggest concern is safety.

There have been a handful of trials of "hypofractionated" salvage IMRT that look good.

Thanks for posting the link, Allen. I was never "worried" but was curious as to whether SBRT lived up to everyone's expectations. So far, it looks like it does, and I am happy you and the others here helped me to go that route.

I can still hear some folks (including one VERY well known uro surgeon/author) saying that SBRT is still an experimental treatment for PCa. At this rate, we will never see it in the mainstream, as by the time it is "ready" there will be something else in the treatment arsenal.

Oh, well. I have only one "customer" to keep satisfied - myself. I'm there.
