I don’t have a precise definition of how the authors defined “low risk,” so I can’t answer your question about that.

However, when they say that “risk of recurrence can be as low as 5% and as high as 20%,” I have to assume only that this is the level of accuracy with which the test referred to can assess risk of recurrence for what they define as low-risk prostate cancer (which we don’t know). Basically, the information provided to date leaves several (too many) unanswered questions.

At present I see no reason to believe that this test would offer any better guidance than the guidance you have received from Dr. Partin and his colleagues.

With additional prospective clinical information, my mind might be changed, but that’s going to take a while.

Since they say your risk of recurrence can be as low as 5% and as high as 20%, does that mean according to them that low-risk PCa has a 5 to 20% chance of reccurrence? I am confused about this.

I had RP at Johns Hopkins by Dr. Partin. I was Gleason 6, organ-confined, no tertiary Gleason grade. Based on the Johns Hopkins article you had here last fall, they say my chance of recurrence is 4/1000. In other words 99.6% chance of it not happening. If I took this test and scored high, would my chances change to 20% risk reccurrence? If so who should I believe?

It appears to me that the additional clinical value of this test is HIGHLY questionable. It appears to me, that the statistical information you quote is not much different than what could be determined from the already known data that resulted in their being classified as “high risk” in the first place. Just an observation!
