HealthBoards - View Single Post - CyberKnive with Stereotactic Body Radiation Therapy (SBRT): Promise & Not Yet Proven

IADT3since2000 · 01-28-2009, 11:17 AM

I've just incorporated a number of edits in my initial post for this thread.

Here they are:

Changed the description of SBRT from Stereotactic Body Radiation Therapy to Stereotactic Body Radio Therapy.

Noted that the usual dosing for other forms of external beam radiation is from 35 to 40 sessions delivering 2 Gy per session.

Added comment that CK SBRT had some good theory behind it, including a link with High Dose Rate Brachytherapy theory and many years of experience.

Added comment on the number of CyberKnife centers in the US, 100, and the number of those that treat prostate cancer, 40, based on viperfred's posts.

Added comment, based on viperfred's posts, that the first CK SBRT patient in the King trial was treated in 2003, giving us five years of follow-up experience with success in both absence of evidence of disease as well as no side effects at the five year point. Observed that this proves success is possible at the five year point, which is great, but does not indicate how likely success will prove to be.

Corrected comment on viperfred's dosing schedule; originally indicated dosing on five consecutive days; corrected this to M, W, F, M and W.

Noted that the CyberKnife users meeting was coming up the first week in February.

(First edit, right after initial posting: had corrected CyberKnive to CyberKnife.)
