Anyone have stereotactic body radiation therapy (CyberKnife)?

You're right @vp3.
"Cyberknife is a treatment using external beam radiation. It is the brand name of a machine that delivers stereotactic radiation therapy or "radiosurgery" (SRS) and stereotactic body radiation therapy (SBRT). Despite the name, Cyberknife does not involve a knife, cutting, surgery, or anesthesia for treatment. It uses a linear accelerator (a machine that makes radiation) on a robotic arm that allows the radiation beam to be delivered from thousands of directions. Cyberknife uses real-time image-guided radiotherapy (IGRT) to treat tumors in different parts of the body, including the prostate. What this means is that the motion of the tumor is tracked, and the radiation can be directed and delivered accurately based on the motion of the tumor."

@colleenyoung I am scheduled for a consult for Monotherapy SBRT on April 23rd . 2025 .
I am currently on Active Surveillance , 4 Cores out of 16 Gleason 3 +3 = 6 with 2 Cores Gleason 3 + 4 = 7 . I am considering SBRT at this time and my query to the Radiation Oncologist will be
" Would you consider 2 Fractions of SBRT to the Gleason 7 Cores Only ? "
It's a curiousity question only . My Urologist, Dr Andrew Loblaw , at Sunnybrook Hospital in Toronto was involved in the : SBRT TOFFEE Meta Analysis - European Association of Urology .
which studied 2 Fractions vs 5 Fractions . He was also involved in the Phase 3 Pace " B " Trial .
I will keep you posted .
p.s. I am 85 years young and in otherwise excellent health , excepr for taking Dutasteride for
my BPH ( was previously on Flomax ) . I may well , at my age continue on AS .
