Jlssmnx, welcome to you!
Some info about
biochemical recurrence (BCR):
* Big picture regarding primary PC treatment methods, 20–40% of patients undergoing radical prostatectomy (RP) and 30–50% of patients undergoing radiation therapy (RT) will experience biochemical recurrence within 10 years
* The American Urological Association (AUA) has responsibility for defining BCR after RP; similarly, ASTRO has responsibility for defining BCR after RT. (ASTRO=American Society for Radiation Oncology)
* Some years ago, an AUA panel evaluated 53 different definitions of post-RP BCR observed int he literature and recommended adoption of this single definition:
.....**
The presence of a PSA greater than 0.2 ng/mL measured at least 6-13 weeks after RP, followed by a confirmatory test showing a persistent PSA greater than 0.2 ng/mLPlease note that your original post was off by 10X (you wrote 0.02, but the AUA threshold above is 0.2), and also did not include the confirmatory and persistent test result greater than 0.2 ng/mL. I'll emphasize the word "persistent" because PSA tests are notoriously imprecise. Their is an important rule of thumb to NOT take action based on just one
unexpected PSA test result. When there is an unexpected result, retest.
Ultra-sensitive PSA assays have recently improved detection levels down to 0.01 ng/mL or smaller, and may possibly lead to better treatment outcomes through earlier adoption of salvage radiation therapy following RP.
However, false positives occurring because of trace amounts of PSA produced by residual benign prostatic tissue, along with uncertainty about
whether ultra-low levels of PSA will be followed by continued PSA increases, have led practitioners to continue to rely on the AUA definition for determining when clinically-relevant biochemical recurrence has occurred after RP. Your up-and-down test results are another mixed-message...PSA from cancer-only goes only one direction.
One other helpful, albeit minor, clarification...you wrote "PT3A
diagnosis" but the "p" prefix indicates that this was your post-RP pathology, not your clinical classification at the time of
diagnosis based on biopsy plus other possible imaging steps.
Your post-surgery pT3a pathology implies "local progression"...PC into the fatty tissue around the prostate, but not to the seminal vesicles or elsewhere, which would make outlooks worse. In the big picture, even with your current local progression, overall PC survival is still very high (98% at 10 years), but a substantial number of men with pT3a do experience BCR and need 2nd-line therapies...which means that you do, indeed, need to monitor PSA carefully and regularly.
My most important comment: if your most recent PSA result was "unexpected" based on the previous results (you used the word "sudden" in the title)...retest.
