Bob Caron - 14 Apr 2006 21:10 GMT I have recurring PC from EBRT,PSA 6 weeks ago was 4.3, yearly physical from my GP indicated a need to lower my cholesterol, he prescribed Lipitor 10 mg. PSA came down to 3.2, thought it was a lab screw up so I had PSA retested,same results. Is this normal? Bob Caron
juniper - 14 Apr 2006 22:11 GMT I can't answer you statin question, Bob, but I'm wondering when you had EBRT, what your PSAs have been since. Are you sure its not just a brachy bump? Also your original dx info would be helpful. Even if not in response to your particular situation today, as a data point for others. As far as PSA in general, it supposedly varies by 30% or so anyway.
"Many patients experience a rising PSA at some time after having brachytherapy. The average time to this PSA "bump" is 18 months. This phenomenon is thought to be the result of radiation-induced prostatitis, a reasonable explanation for this bump in PSA. This stressful event can be avoided if patients know that a rise in PSA may not necessarily indicate a recurrence of the cancer, pending the timing of the PSA rise and the history of having received brachytherapy.

>From the quote above, if the brachy bump was caused by prostatitis, then the reduction would also fit. I realize your question is still unanswered about statins.

Sure wish this is a "bump" but I really think its the "Lipitor" Weighing my options now,Cryo, HT, or, I can get into a clinical trial which would be a Phase II,comprised of 4 months of weekly chemo of Taxotere and Doxorubicin,followed by 12 months of total Androgen Suppression. Any thoughts are welcome.

If the PSA=1.1 on 01/01/05 were an error, then the timing of the PSA excursion would be like a bounce. Of course, multiple bounces aren't that uncommon either. A couple of things you could do, go to Don Cooley's site at http://www.psabounce.prostate-help.org/studies.htm where he has a whole section on the bounce. You can read study abstracts, read bounce histories from other "bouncers" and submit your own data to him and he'll give you his opinion as to whether he thinks it's a bounce or not. He knows quite a bit about these things. I would certainly try to sort this out before starting into any heavy duty treatment. As to the Lipitor, it is thought that statins are protective against PCa, but once PCa is present I haven't read anything that statins lower the PSA reading (but I certainly might have missed something)...Good luck, Ron

We're going with Taxotere and Androgen Suppression, but I neither recommend nor dis-recommend it. Steve gets dexamethasone 2 days before (oral), IV on chemo day, and 2 days after the Taxotere.
I was doing a lot of study on the Taxotere, and found one study that said that taxotere every 3 weeks was far more effective than Taxotere once a week (same length of treatment). All of this information is just off the top of my head. These really are just "thoughts." I could try to find the reports if you like. I usually use Google and Vivisimo for searches. It said that weekly Taxotere was the same effectiveness as Mitoxantrone (the previous chemo medicine of choice), but Taxotere every 21 days was several times more effective. Ralph told me that the 21 day dosage was designed to catch the cancer cells just as they started to recover from the previous dose. Another study said that weekly dose is as effective as 21 day dose, but for some reason I had the impression that this was not a completely objective report. Like it was the manufacturer or something. I gather the side effects of a weekly dose are generally easier to take. But Taxotere is supposedly "not bad" for side effects compared to some. But who knows what anyone's SEs will be. At least with your trial, they are using the most current chemo. The one we were offered was with Mitoxantrone, which is looking far less effective than Taxotere.
There are various steroids involved in his treatment also, plus some IV anti-nausea. And he is taking Casodex daily for the duration.
Obviously we opted for chemo, hoping for a cure. We had a RP that documented mets, though. In your case, I don't know if you know enough. Maybe the cancer is still in the prostate and the brachy just didn't get it all. That happens. But if you are at the limit for RT I guess that wouldn't matter. Are there tests? Cancer markers or something? Prostascint? Trouble with Prostascint is it is not very dependable. I think G6 cancers are slightly less likely to be metastatsized than higher numbers. Dr. Barken told me he believes that all PCa is systemic.
We did end up going with chemo, but we did not do a trial because we wanted our onc's best idea for treatment, and that wouldn't have happened if we'd done a trial. We would have been limited to their protocol. Also we have ADT and chemo together (the ADT will continue for probably a total of 24 months). Those kinds of details we leave up to the onc.
Best wishes, Bob.

I don't know if he's right or not. Your numbers are high for a bounce, but not unheard of. Apparently there's a recorded case of a PSA of 15 after radiation that came back down again.

I guess a great deal depends on whether your recurrence (assuming it is a recurrence) is local or not. Have your doctors ventured any opinions about that? Have they given you all the tests to try to find metastases?
If it's local, maybe cryo or HIFU would kill it. But maybe not. It may be almost local, but spread into areas around the prostate that the cryo won't reach.
This is a very tough call. I'd suggest getting some opinions from other experts - particularly from the cryo guy, and from a medical oncologist specializing in PCa. Whoever does the clinical trial might be an expert you could consult.
Don't give up hope. There's still a decent chance that you'll live for many more years and die of something other than PCa. You'll almost certainly live long enough to try out some of the new treatments that will become available in the next 5-10 years.
Good luck.

Bob, do you have any additional information about this trial. Is it an international trial?
Bob Caron - 15 Apr 2006 18:58 GMT This trial is being conducted at the University of Maryland Hospital in Baltimore Maryland. it is identified in detail on their web site. Bob

Alan Meyer - 17 Apr 2006 02:55 GMT > This trial is being conducted at the University of Maryland Hospital in Baltimore > Maryland. it is identified in detail on their web site. > Bob Bob,
The University of Maryland has a good reputation both for treatment and research. If you haven't done so, I suggest that you call them, tell them you're interested in the trial, and would like to consult with one of the doctors to find out more about what they're going to do, what the side effect will be, what the prospects are for successful treatment, and whether you are a good candidate for the treatment. Ask them if there's any charge for the consultation, but my guess is that there won't be.
They're not going to make any money by treating you, and they have a strong interest in getting good results.
The doctor you talk to will likely be a research scientist as well as a medical practitioner and will likely be knowledgeable about the latest research. Hopefully, you'll get unbiased, expert advice about whether your cancer is likely to be treatable by cryo or HIFU, or whether this trial is a good bet for you.
Let us know how things turn out.
Good luck.
Alan
