Is this PSA expected 5 years after SBRT?

Posted by modeler @modeler, Mar 3, 2023

In September 2017 a biopsy diagnosed me with prostate cancer (T1cN0M0, Gleason 7 (3+4)). I was 71 years old at the time. It has now been 5 years since the end of Cyberknife SBRT treatment. My PSA has declined from a pre-treatment value of 7.3 to a current value of 0.61. I am somewhat concerned that my PSA first reached a minimum value of 0.50 and recently bounced slightly to 0.61. Is my experience consistent with others who have had similar SBRT treatment? Is a leveling off at about 0.50 expected behavior? Does my PSA data provide any insight about a re-occurrence?

Please see the attached plot of my PSA over the past 5 years.

Comments from others would be greatly appreciated.

Thanks !!!
Yes, once the cancer cells are in us, all we can do is control them. That is why (anymore) men seldom die "from Prostate cancer" because of the way it can now be aggressively treated, thus I am confident that although this regiment of treatment may sap my energy level, and that I will have to more closely monitor my bloodwork, while supplementing myself with more pills, that I will be around for a long time!!
