I too had Gleason 9 and it does seem to be the thing my oncologist is most concerned about. They don’t tend to mess about with a 9. I also had positive margins, extra capsular extension, perineural invasion.
My post Surgery psa was 0.014. Over the year it went up to 0.023. My oncologist said something was going on. The problem is, with such low readings it’s almost impossible to find out what is going on.
At the risk of wasting my money, I paid was a psma scan. It actually work and found small areas of cancer is two pelvic lymph nodes. After targeted salvage radiotherapy, my psa is now >0.006 and has been since August 2018.
The sensitive psa test seems to cause as much controversy in the urological community as it does in this forum. I credit it with saving my life. How long would I have waited at >0.1 whilst the cancer was spreading?
In your case, you know something might be going on and that’s a good thing. They’re monitoring you and you’re on their radar screen. They’ll move quickly enough if they feel they need to
if you do need srt, ask about hormone therapy in combination. I had 3 months bicalutimide before starting with 18 months in total
