Bobbiesan many thanks, I have been pondering this for 2 weeks.
Many have just given the advice that since the levels are low they are harmless now and in the future which is only subjective speculation.
USPSA offers the promise of early detection and better outcomes which I need and value being 58 years old.
I got tested on back to back days just to eliminate testing measurement error (got 0.01 and 0.009).
I am going to be tested every 4 weeks at LabCorp for at least 6 months in the hopes of a stable flat baseline. This is my plan as the medical system is not setup to proactively tackle this issue.
Will plow through the research and read the threads.
I am a retired CalTech pure science grad who happened to stumble into a living writing software most recently in BigData https://en.wikipedia.org/wiki/Big_data 4 years ago before retirement.
There is a mountain of USPSA testing data coupled with real life outcomes that has never been processed to assess BCR risk.
My margins are barely negative. Did you posit that negative margins are a drawback detectable USPSA level ?
My pathology was deemed positive and I got the thin margins rechecked by Epstein at Johns Hopkins.
my updated profile is
58 years old
RALP UCSF 11/19/15 Dr Carroll
PSA 19 months clean until positive at 22 months
1/14/15 5/4/16 8/29/16 12/1/16 3/3/17 6/5/17 9/15/17 9/16/17
<0.015 <0.015 <0.015 <0.015 <0.015 <0.006 0.010 0.009
1.2 cc tumor
clean margins, less than 0.1 mm from ink
Gleason 3+4 20% 4
I thought I was done with prostate cancer / BCR this June 2017 when the testing threshold at LabCorp was dropped to < 0.06 and I cleared it being lower than the threshold making it 18 months.
I have taken and do take vitamins and in particular B vitamin supplements daily which baffles me because I tested below < 0.06 in 6/2017 while on them. Regardless I will stop taking them 3 days before retesting in 2 weeks which will give me a 4 week time window. I want to eliminate testing noise and establish a baseline rate of change.
It bothers me that I have gone from 0.006 < to 0.01 / 0.009 in 100 days which implies fast growth. The concern is a small amount of fast growing tissue that has always been there.
The new research seems to favor SRT at USPSA levels between 0.05 and 0.03 which I am only 3x aways from.
A key risk factor is the PSA post op nadir being >= 0.08 which I do not know along with most other patients https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4106725/ as my nadir is presumed to be < 0.15.
