My psa 7 years ago was 0.3 and repeated 6 month 0.6 ng/dl. DE was questionable but gut feeling suggested biopsy. Two quarters positive I believe 3+3. Surgery (at age 65) found envelope penetration at one point. Urologist felt good about procedure and results (DiVinci). My post initial value in 3 months was <0.08. Thanks for the excellent answer. This is great information. With testing every three months post-prostatectomy, my PSAs varied in the 0.02 - 0.04 ng/mL for about a year, then finally dropped to undetectable where it has remained for the last 5 years. PSA pre-surgery was 7.4. PSA vs hook-it. I'll go with PSA. I've used both systems for years. Hook-it is out of the picture for me. When the loops on the pad wear out, the disk tends to fly off the pad. If you keep your PSA pad clean, re: adhesives, you can get great performance out of a PSA system. WD-40 is a great cleaner to get the glue off. Labcorp has an ultra sensitive test that will go to .006 before it reaches undetectable. It's the one I prefer and was recommended by Snuffy Myers several years ago. It detected my rising PSA at its earliest stage last year and allowed me to qualify for Provenge treatment when it is the most effective - when you have a low PSA. At PSA levels <0.20 ng/ml, nomograms and clinical reflection are probably superior to next generation imaging. We must understand cancer biology rather than just irradiate the pelvis when PSA Open till six weeks ago I was on Xtandi for a year with an undetectable PSA. Six weeks ago I stopped taking the Xtandi but continued with my Lupron and my PSA has gone up to .04. My question is should I get back on the Xtandi or possibly try Zytiga and prednisone. My understanding is when I become resistant to the Zytiga that the Xtandi has a .
