4 years post EBRT (44) PSA 0.1 Up from undetectable.

[Chasu]

MO thinks it will go up hopefully slowly. Recheck psa in 3 months. Dumb question maybe. Stage 4?

I would have to agree with Hidden - 0.1 is an OK result in my book. That can easily be a lab error*, or a new machine, or a new tech running the old machine.

Is this with the ultra-sensitive PSA test?

Were you always getting ultra-sensitive PSA tests?

The reason I ask - is the "standard" PSA test normally cuts off at around 0.12 - and below that is listed as "undetectable" because the machine can't read it, not that there isn't any PSA. The PSA could be 0.11 and the machine would give "undetectable".

If you didn't have surgery it's absolutely normal to have a low level PSA number - as long as it stays low you're good.

* errors in the lab - I had two blood draws during the same blood leach session - both for PSA tests (two different MD's) - one came back something like 0.17, the other 0.22 - same day, same machine, same tech and same blood really. Significantly different numbers. It happens. I believe the 0.22 number was accurate.

I'd not lose sleep over it (I know - easy to say, hard to do) - and wait for your next test. Press your MD to do one in a month, if he won't find another MD (I have 3 that I use to get frequent PSA tests) who will. Also get your T tested at the same time, you want to keep track of that vs the PSA numbers. They do tend to track together, and that's normal.

It seems your nadir was essentially zero, correct? THe general rule for assumed PCa recurrence after RT is nadir +2. Was this not mentioned to you? Surgery is a different ballgame it seems!!

Recurrence is suspected if PSA is 2.0, not 0.1. 0.1 is excellent!
