I just got my monthly PSA and T results. I am not on any ADT medications for about 17 months now or any medications for that matter.
last month results: psa(.11) and T= 700
This month(today): psa(.19) and T=130
I can understand why psa increasing but why T dropped to this level. Is this considered castrate resistance?
Thanks in advance for your thoughts
700 to 130 with no adt ,in one month? Wow ! I’m hoping someone can tell us what that means? How do you feel ?
I feel the same. I wasn’t expecting it to be that low considering I am not on any medications. I just sent a message to my MO and asked for a psma scan. I think no matter what the scan shows, I need to go back on ADT. I hate going back on it obviously.
It good that you don’t feel worse . I’d think you’d feel a big difference? We all hate adt . We hate pc more . Good luck . I’m hoping it’s a blip.
I did an orch after two yrs lupron but stayed on a pill adt for over seven years . I stopped the pills 9 months ago . and my docs didn’t want me off it due to my k failure start with pc . Nobody wanted me to go back there again . I know some say monthly psa . I done tri-monthly this entire time . I’m thinking monthly could drive some unwanted stress in me . Plus I hate giving blood . Good luck !
I was reading a list of trials at University of Chicago and TAK700 is on there.
i thought they stopped doing tak 700, years ago?
That was my impression as well which is why I was surprised to see it. It was not a monotherapy trial that much I remember.
Why would you go back o. ADT with PSA so low after such a long vacatión? Your thinking seems contradictorio. We go on ADT in order to bring our T down. You want to go back on ADT BECAUSE your T is down?
I am very nervous. It’s not about my T LOW. it’s about psa rising with a one month doubling time. The T is probably a glitch.
As my husband's doctor stated from day one, cancer cells will adapt and learn to survive and multiply even with low testosterone levels. At that point it is the PSA level and doubling time which becomes most important. Rising PSA means cancer is becoming more active and most likely spreading. Listen to your doctor about ADT.
I also had the T level tested in another lab and it was 550 on 3/15/23. So, I am beginning to think it might be a lab error?
It sure could be ! Next test will tell ! Good luck finding out!
Thats weird. I wouldn't worry about it much until the next test. It may be a test error. Are you sure they are both total T as opposed to free T or something like that?
it says total on the test.
Almost has to be a test error. Whens your next PSA test 1 or 3 months? Get T done again then.
my best mo wanted me to get all scans and testing done at the same place every time . More chance of accuracy .
How are you feeling?
I am feeling good. No issues so far.
That’s good! 🌵
You don't actually "feel" anything until you are much worse.
That’s not good! 😔
What do you mean by “ much worse”?
I mean if and when the cancer progresses because treatment stops working. Then you have pain...as the cancer gets worse. Not just the usual discomfort from treatment side effects. But that's after exhausting the many treatment options available. It's great you are feeling good, a good sign!
thanks. It was a lab error. The new results is 704
Any time we get weird data the first thing to do is retest. Labs are not perfect.
Just a thought. PSA can rise due to physical stimulation such as a DRE. Maybe the T=700 was high due to something like that.
Doctors know better than to test PSA after a DRE
I'll second and third getting a retest done. I could go on and on about Quest labs- one of the two big labs in NJ area. "Never blame something on malice that which can be explained by incompetence" should be their motto.
I've posted before about the two PSA reads done, on samples taken at the same blood draw, obviously the same day, minutes apart, processed in the same lab by the same technician, and giving results that were significantly different (more than 30% different.) Any time I see significant changes in a test result - it's time to start looking for what they screwed up, not what caused the change.
That's why doctors say wait for three months then test again. Accuracy and doubling time are both important.
I have experienced a 10% difference in readings on the same blood taken the same day requested by two different doctors. More important than the actual number is the trend in numbers. The PSA velocity rules the day.
Yes - the trend is the most important thing. Mine has a velocity of zero, up or down. It wobbles between 0.17-0.21, the most prevalent ones have been in the 0.20 range for over 18 months now.
wow. You are lucky that it stayed.
Test error, My doctor had me do another blood draw when that happened to me. That happened to me only once in almost 6 years.
Screwed up test. Ive never had one that far off but 100 points has happened. Never gone down dramatically.
In 2020 you report pelvic and abdomen LNs on PSMA scan. You went on Firmagon ADT in Nov 2020 for one year. I am presuming that you had SBRT to the LNs at that time ( You don’t mention it in your profile.) Now, your testosterone recovered band your PSA is again rising.
This represents remaining sites of metastatic disease. It does not mean castrate resistance as it is not rising while on ADT with total testosterone of less than 50 ng/dL. The majority (2/3) of those with LN oligomets treated by SBRT have recurrence in nearby or distant sites within 2 years, unfortunately. If your PSA continues to rise at this rate it will be above 0.25 by next month and you could get a repeat PSMA scan to see if there is something appropriate for further treatment. Or if presumed to be more widely metastatic then systemic treatment, including ADT, may be needed.
Since you are not yet confirmably mCRPC, you will not qualify for some treatments including Provenge or Pluvicto. Lu177-PSMA treatments could be undertaken in Europe, Australia or India (self-pay). These appear to work better in LN only disease and with low tumor burden.
I have no idea why your T level dropped this month. Check what Free-T did.
your analysis is correct. I was not offered radiation before I started ADT in 2020. I don’t think I am castrate resistant. It must be a lab error or something else but I have no idea. I contacted my MO and they told me they will do the psma before my next appointment in early June. I understand that ADT is in my near future. I had a defused disease in the LN in abdomen and pelvic that is probably why they never offered SBRT of some sort. The question is: at what level of psa should I resume ADT?
That's what doctors are for.
it was a test error. The portal results got updated to 704.
.19 is probably not high enough to scan yet. Try again next month, maybe it will go down. Its so hard to rely on one or two PSA tests. And the T fluctuating; I know this is a an unusual theory, but I wonder if it is the body trying to regulate itself against the rising PSA. and perhaps next month will be lower. I know that sounds like an unusual idea.
PSA and Testosterone 
Two years Results
Low PSA and high T=?
Miracle results!! But intermittent ADT ever ?? 
Not sure how to interpret results of new tests
