PSA3 is a new urine test and the prostate gland has to be massaged before you pee in the cup. Tests like PSA3 and free psa are ways to indicate the likelyhood of PCa vs BPH and are very useful in determining if you should get a biopsy or not. It does not replace a biopsy.
Since PSA3 is relatively new we really don't know what the numbers mean because there hasn't been a lot of data generated yet. High normal for a PSA3 test is 35 and any number higher than this indicates a probablity of PCa just like a freePSA score of less than 20% indicates a probability of PCa vs BPH.
My Doc thinks that the higher the PCA3 number is the more agressive the cancer is, but at this time without any long term studies this is just a theory.
PSA3 is just another tool and we need all the tools we can get.
I have not suggested it replaces a biopsy but that it is an additional bit of information that you would not have otherwise.
And it does not indicate the likelyhood of cancer, it is either inconclusive due to inadequate material epressed, or it is postive for cancer or negative for cancer. I sure whish the cup I peed in before I was subjected to ADT and IMRT because the Dr. said I had a local issue had been subjected to this inexpensive test.
It is not new except in the US.
