Cyberknife

Read something on the web about Cyberknife treatments. Need verification
of 5 treatments only given because that is all Medicare approves. Any truth to this? Are more treatments necessary?

Re: Cyberknife

Hi Bill,

I would be shocked if that were true about a Medicare limit.

The five treatment approach is a pioneering approach using theory/and treatment methods known as Stereotactic Body Radio Therapy (SBRT). It can be delivered by a wide range of radiation systems, but it is most closely associated with CyberKnife. In fact, studies are going on using some other systems with fewer than the traditional 40 or so external beam treatments but more than the 5 associated with CyberKnife SBRT.

There's an encouraging post about a recent, key research report that documents quite successful follow-up that averages (median) about five years. There was some good sounding theory predicting that the five treatment approach would work, but no one really knew for sure that we could have good five year outcomes until this study.

It's amazing how urban myths get spread around the Internet!

Take care,

Jim

Re: Cyberknife

It will be 4 or 5 treatments, usually every other day, or every day, depending on your Radiation Oncologist. No further treatment is necessary, and all functions are well-preserved.

There is study of the five year CyberKnife results, which you can read at the following link:

Five treatments is correct for hypofractionated PC radiation therapy-and it has nothing to do with Medicare. The rest is that it must be completed in 11 days-according to the study that I am in. High dose over a short period is what PC responds best to. This is why High dose brachytherapy works so well and CyberKnife's pinpoint imaging lends itself to delivering the same dosage using an external beam.
