PSE Test for Prostate Cancer Before an MRI and for Re-Occurrence

Posted by bens1 @bens1, Oct 22 8:31pm

I had a discussion with a SVP at Oxford Biodynamics last night about the accuracy of their PSE test for both potentially new prostate cancer patients and for those that get tested for biological re-occurrence. He basically explained, in layman’s terms, that regardless of having had treatment or not, the PSE tests 5 biomarkers will be accurate to show the likelihood or not, of prostate cancer 94% of the time.

He said that a change at the cellular level, because of new cancer cells, even when a psma pet scan will not pick up the micro cells, that their test will pick it up.

I have attached a chart he provided. Obviously part of his job is to spread the word, but I believe his intent to help was genuine. He also said that anybody that wished to email him to ask any questions to feel free to do so. His name is Steve Arrivo and his email address is: steven.arrivo@oxfordbiodynamics.com.

I completed salvage radiation last May. I have been on ADT for 11 months (6 months of Eligard followed by 5 months of Orgovyx + Abiraterone. My original episode was in September of 21 when my PSA was 23. I had RP - pathology was GS 4+4 stage Pt3b. I had persistent PSA, 60 days post RP PSA was 7. Did about 2 years of intermittent Bicalutamide. Went to Houston for RO consult. They put me on the Eligard and performed the SR. Last PSA was < 0.01. My MO thinks i have a good chance for cure but wants me on ADT another 7 months for micro metastases . I wonder if a test like this could tell if there are any micro metastases or if it’s safe to stop ADT?

Whether it is safe to stop. ADT depends on your Gleason score. If it is seven, you can stop after six months if it is eight or higher, you need to go 18 months or more in order to make sure it doesn’t come back. That doesn’t even guarantee it won’t come back, but it does allow some people to go into remission.

You need a PSMA pet test to see if you have metastasis that have gone beyond Micro, you would probably have to do that after you stop taking the drugs because your PSA has to be higher than < .01. . You do have to realize that prostate cancer is in your bloodstream and will stay there. The best chance of getting rid of it is stay on ADT for the recommended time.

Having a PSA of seven after an RP, and not treating it with SR is almost malpractice. Sure you can keep the PSA down by putting you on ADT drugs, but that seven means you had something active that should’ve been treated. Doing that so late may leave you with a much higher chance of recurrence than had you been treated properly.

Six weeks after my RP my PSA was < .1 and stayed that way for 3 1/2 years. Then it started to rise and when it hit .2 they did SR. That is the standard treatment that is supposed to be given, and you were not given that

Six months post HoLEP prostatectomy my PSA was at 0.911
The urologist surgeon said "you're cured." Come back in six months for another PSA." I asked why would I need to have another test if I'm "cured?" He said it's standard. I asked why and he said it was to make sure there was no cancer. I commented that the "cured" statement is moot. When he told me my PSA was .911, I mentioned that it should be < 0.2
He said that I still have the capsule, that it could be any number, that perhaps I have "another cancer." But, other cancers don't produce PSA, it's a marker intrinsically made by the prostate.

I’m a little confused by your statements. HoLEP is not the same as a prostatectomy. It removes some tissue, but is not the same as a prostatectomy done under surgery. You are right, another cancer would not raise your PSA. The question is what was your PSA after six months? I would’ve wanted it tested after three months.

If you had radiation, it would not be completely unusual for you to have a PSA of .911. It should continually go down, though it might bounce around a little, but it could take a while to hit bottom. HoLEP results may be similar to radiation, I don’t know. Maybe someone else here does.

Yes - I was being treated by a very reputable urology oncologist in Mexico City, but if I had known then what I know now, i would have had SR much sooner. I did have a PET/PSMA a few months before i started the Eligard and it showed no spread beyond the prostate bed. My surgery was nerve sparing and I suspect he left tissue there that contained cancer - that is purely a guess.

You're right. Pardon my confusion. The prostate is lased away into sections and extracted laproscopically through the urethra using a morcellator. The prostate is analyzed in pathology. The capsule of the prostate is left intact. I have had no radiation, or any treatment, or any diagnosis of cancer. My PSA after six months was 0.911

I have to pay a private doctor to look at my results post HoLEP laser enucleation.
I have some unusual bone pain and a PSA of 0.911 six months after the surgery. My prostate capsule was left intact.

I need to add that I have read both treatments as "prostatectomy" and "enucleation," which implies total prostatectomy because the gland itself is removed, not it's capsule. It's the same kind of jargon they use on patients that go in for "laser hair removal." It does NOT remove the hair, it "reduces" the growth. It's a consumer / patient / doctor sales terminology. I used to operate all of those lasers in operating rooms and clinics, all types of lasers.

They did enough tests to determine that the cancer had not pierced the prostate? What was your T level. T2 or T3a or something else? Coming out of a total prostatectomy your PSA should not be .91, if it rises over .2 NCCN guidelines call for salvage radiation.

Maybe that procedure is so different that they can say it’s OK to have that high a PSA. I think it might be sensible to get a second opinion from an oncologist, preferably a Genito urinary oncologist.

Less than/ more than - reverse them. Lol

Ultrasensitive PSA doesn't give you a specific PSA number if it is less than 0.01?

This is why I'm asking, around here. So far, all of the rabbit holes I've been down, all say < 0.01, or < 0.02. There is nothing that says it is okay for it to be 0.911, except the surgeon. I'm in Spain, socialized healthcare where the doctors here are accountants before they are doctors.
I just ordered another PSA from an independent clinic UniLab in Barcelona. If the result is less, doubled, or the same, I will consult a private doctor for a second opinion.
