Question for Ken - How soon after your surgery did you find your PSA start creeping up? Or more specifically, how soon after surgery were you confident you had a recurrence? I'm afraid that I may be heading there and/or will need RT. My pathology indicated a focal margin as well. My 6-week post-op PSA came back at <.01 but my four-month post-op PSA came back at exactly .01. I am scheduled for another PSA at the end of this month and of course anxiety levels are high.
Grandps Tim 5 - You didn't mention what your husband's PSA was, staging, and other information from the pathology report. But gleason 6 is generally not as aggresive as a gleason 7 or higher, so you have that in your favor. And if the pathology report does not indicate lymph node or seminal vesicle involvement, then again that's information stacking the odds further in your favor.
Every case of prostate cancer is as unique as the individual diagnosed with it. Don't get too caught up in relying on statistics (something I myself am guilty of).
What you need to focus on now is healing. Time will tell if further therapy is needed soon, later down the line, or you may find that further treatment may never be needed.
