I just had two PSA tests at different hospitals 4 days apart. The first was for my MO. The result came in at 1.54. That was above the high end of my expectations after a .9 three months ago. I was hoping for a 1.3 or below as a sign of a decreasing or, at least, stable doubling time. I wasn't happy with the result but, it still showed a doubling time not all that much below my previous test. Not a big enough difference to jump to any conclusion about
rate of increase.
But here's the disconcerting part. Four days later I had another test - different lab - for an appointment with my RO. This appointment was scheduled 6 months ago and am expecting it to be a farewell with RO now that I'm in care of an MO. But the result came back at 1.88 - a very large difference from the 1.54 at the other hospital. I'm sure the difference has to do with the assay - not with a mere 4 day interval. But now, if this result should bear out -- I'm seeing a doubling time of 3 months rather than the 5 or 6 months based on the test 4 days earlier. If this test should turn out to be accurate I'm now seeing a bigger problem than I thought I had -- not just an increase that I know means I'm heading for Lupron, but also a sudden doubling of the rate of increase in three months time.
I guess I'm not expecting advice. Just wanted to whine a bit about
the erratic nature of this disease. Especially in light of my 15 years experience thus far of very slow rises--years--between treatments that eventually, but very slowly failed.
