What's typical PSA drop over time after SBRT?

[LiveLongAndPropser]

Hi All,

I'm 10 months post SBRT w/o ADT (on a study that randomized me for no ADT with low Decipher score), so wondering if anyone has any info on what I would expect for PSA percentage drop over time? A year ago my PSA was 11.0 and this past week, I'm at 5.3. I'm happy that it is less than half what it was, but wondering when, or if, I should expect it drop to below 1?

Thanks,

Trevor

Hello! Glad to hear that things are going well I am 6 months out from my Cyberknife. I started with a PSA of 13.72, then 3 months later, it came down to 6.97 and now 6 months after, it's at 7.69.

My oncologist is ok with it and told me that it can go up and down for the 1st year but my urologist was very alarmed and stated that it should be much lower at this point.

I would love to get everyone's take on this as well.
