Here is one such study:https://www.ncbi.nlm.nih.gov/pmc/articles/pmc4586061/
the prostate specific antigen pattern during the first 3 years of followup to divide 566 men into 3 groups, including 1) undetectable prostate specific antigen (0.03 ng/ml or less), 2) low detectable-stable prostate specific antigen (greater than 0.03 and less than 0.2 ng/ml, no 2 subsequent increases and/or prostate specific antigen velocity less than 0.05 ng per year) and 3) low detectable-unstable prostate specific antigen (greater than 0.03 and less than 0.2 ng/ml, 2 subsequent increases according to NCCN criteria and/or prostate specific antigen velocity 0.05 ng per year or greater). The primary end point was biochemical recurrence, defined as prostate specific antigen 0.2 ng/ml or greater, or receipt of radiation therapy beyond 3 years of followup.
Seven-year biochemical recurrence-free survival was 95%, 94% and 37% in the undetectable, low detectable-stable and low detectable-unstable groups, respectively
Please note that even in the 2nd group(worse, low detectable-stable prostate specific antigen (greater than 0.03 and less than 0.2 ng/ml, no 2 subsequent increases and/or prostate specific antigen velocity less than 0.05 ng per year), this group of men who reached .03 but less than .2- still 94% were BCR free at 7 years! This compared to 95% in the group who stayed below .03% for the first 3 years. IOW, no difference.
the worst group, > .03 plus some other negatives: still, 37% HAD NOT BCRed at 7 years.
So, getting over the .03 mark in the first 3 years ( in this study at least) is a negative, but still a bit far from a guarantee of BCR within 7 years. There are other studies with somewhat different results, showing a greater likelihood of BCR someday if ever reaching .03.
OTOH, the OP ( Oldbeek) is not .03, but .08, up from a recent .05. So the trend seems to be in the wrong direction, as well as over .03.
