On September 9, 2010 I had the last of a series of pre-procedure PSA tests: the number came in at 5.54. (I was dianoses as t1c; four cores positive out of 12, gleason 6 in late June).

I had brachytherapy (108 iodine seeds) on September 28th.

On November 1st I underwent a bunch of blood tests on an unrelated matter at the hospital. They tested my PSA at the request of my prostate cancer team just to see how things were going: it came back at 7.88.

On Wednesday I reported to the Prostage Cancer Centre for a third-month check-in. PSA test done again, carefully and on schedule this time. I got the results this morning: 4.54.

I asked my doctor what to make of these results, and specifically what to make of the relatively high number in November. In summary, he said that the November blood test was not to be relied on, since the radioactivity was at its peak inflicting trauma on the still alive-and-kicking prostate and that was artificially increasing the PSA number. This would likely to still be true for some time to come.

He predicted this week's number would be lower (as it was) and would therefore be moving in the right direction. He said as long as that is true there is no reason for concern. Things are going according to plan as long as the number does not spike upward or keep going upward. See you in March for the six month test.

Anyone have comparable experience or a view on this?

As long as it is moving sown there isn't a problem. Idodine has a much longer half life than pladium 105 and should take longer to work. There are many men on Brachy that have seen reductions of up to 4 years before seeing the nadir. many claim the longer it takes to reach a nadir the less chance of a reoccurrance.

When I finished my IMRT treatments I asked my radiation oncologist what PSA numbers to expect after the seed implants were in and we waited 6 months. He said in my case if we were at or around 3 he would consider the treatments to be working. If the number was around 30 then he would think that the treatments didn't work. We all want the trend to be downward.

Best wishes on your next test.

Brian, interestingly enough my docs (both urologist and radiation oncologist) wanted to wait a full 6 months post brachy before doing a PSA.  I was Iodine also and that was part of the logic.  At the 6 month time they wanted to see the PSA cut in half before they would be "delighted".  As JT said it can take years before you reach your nadir and as long as it's heading in that direction you should be fine.  I have read at least one study (that I can't put my hands on right now) that quoted the median time to nadir as 40 months.  Obviously then it could be much longer.
 
I think your PSA test might have been a bit early but the PSA is heading south and that's what you want.  Continue to enjoy life and assume the best...let us know at 6 months...chances are you'll continue to drop.
 
Best regards,

Very reassuring! Thank you all and all the best for the season -- including, I hope, better sleep at night.

My R-doc, a man of considerable stature in the field, says 6 months is soon enough for the first post-treatment PSA...Radiation works slowly, PSA anxiety is bad enough as it is..

In my case, the RT is being combined with HT so it becomes very difficult to determine which treatment is responsible for any dramatic drop in PSA if indeed there is a drop....I'm more concerned what my PSA will be in two or three YEARS not 2 or 3 months...Living for that next PSA test is no way to live...If tomorrow looks like it's going to be a good day, then make a good day out of it!

I had brachy on Oct. 4, 2010. I go back on Jan 6 to check the PSA. I would rather wait longer...much longer, but that is what the doc wants.
