Colonel Saunders - 26 Apr 2008 00:33 GMT
Greetings from the Art Deco capital of the world - Napier, New Zealand

I have been diagnosed with Prostate Cancer.
I have had a biopsy  which confirms the cancer.
I have had a bone scan that confirms that the cancer is limited to the
prostate.
I am to be scheduled for surgery in June/July.
Since I last saw my surgeon I have had another PSA Test.
These are the results of all my PSA tests:
FEB 04    4.9
OCT 06   6.4
MAY 07   8.7
NOV 07   8.0
FEB 08     7.7
APR 08     6.7
I would appreciate anyone making an observation as to the possible reason
for the decline in my readings over the last year, and the significance
thereof, if there is any.
TIA

What was the Gleason score? This is vital. How many specimens were taken
and how many of those specimens showed evidence of prostate cancer (PCa)?

What is the clinical stage (CS)? This is expressed as the TNM (Tumor,
Nodes, Metastases) score? Usually, at this early point, the CS is
usually expressed as just the volume. For example, T2c, which means
Tumor stage 2, involving both sides of the gland.

One hopes that that is accurate. The bone scan is notoriously crude. It
will not detect micrometastases.

What is the size of the prostate gland? The normal prostate produces
PSA. The formula for computation of normal (benign) PSA is GV (gland
volume) x 0.066 = benign PSA. Anything in excess requires explanation.

Did the uro prescribe a course of treatment (tx) for possible infection?
Cipro, for example.

The above record looks to me like an increase, not a decline.

Without the Gleason information, it is simply impossible to understand
the situation.

I recommend that The Colonel join us at http://www.pcainaz.org/ which
was for Arizona folks until the rest of the world discovered us. There
is a fine contributor named "Chris" who is also an Enzed. Please join us
on our international chat, accessible via the above site on what I think
is Sunday AM in NZ. It's necessary to register, which is easy and will
not result in spam.

The test of choice for this would be the CT scan.

Oops. Must have had my eyes crossed.

Hi Colonel...It could be normal variation, a lab error, or something
else.  Perhaps  the following questions might help point to something:
1) are all measurements from the same lab?
2) any new meds or supplements?
3) do you have a history of prostatitis, or any other UTI's?
4) is your testosterone low or falling?

PSA values can jump around for a variety of reasons.

But at this point, it is moot, if you have been diagnosed with prostate
cancer through a biopsy.

Your biopsy should have given you more numbers, including Stage and Gleason,
and what is your age?

Based on your 2004, 2006, and 2007 PSAs, I'm wondering if your doctor was
alarmed and has been treating your for another prostate problem.  If so,
especially if you were given new meds in May 2007, or maybe even statins or
Celebrex for other problems, your PSA might have gone down.

It matters not in the long run.  You cancer is confirmed and will not leave
your body on its own.

Sorry to welcome you to our club.

Steve,

Is there somewhere I can look into the relationship between
statins/celebrex (I've had both) and declining PSA?
