Is there an expected or standard curve for the percentage of reduction of PSA after CyberKnife? Mine started at 4.7 and seems to be reducing at about 25% every 3 months for the last 9 months. Is this good enough? Does it meet normal expectations? I was diagnosed with T2a PC with a Gleason 8. Imaging showed no lymph node involvement and all is encapsulated as far as they can tell me.

My 1st result after CK was 6.9. The 4 month changes were reductions of 45%, 32%, and 20%.
