I came across this interesting abstract of a study in Germany that suggests defining biochemical recurrence after radical prostatectomy at the 0.1 ng/ml level instead of the widely accepted 0.2 ng/ml.
The vast majority of patients with PSA ≥0.1 ng/ml after RP will progress to PSA ≥0.2 ng/ml. Additionally, early administration of SRT at post-RP PSA level <0.2 ng/ml might improve freedom from progression. Consequently, we suggest a PSA threshold of 0.1 ng/ml to define biochemical recurrence after RP.
You can read the full abstract here.
Of course, with my latest PSA at 0.08 ng/ml, that’s far closer to 0.1 than 0.2. I know it’s just one study, so I’m not going to get worked up over it for now. Something else to talk with the doctor about in September (gotta keep ’em on their toes!).
