So my father had another PSA check yesterday and it’s at 0.05, when last month it was 0.04 and the month before that it was 0.03. The doctor indicated that everything is “fine” and they will have PSA check ups every 2 months now instead of every month. I’m concerned that this is a bad idea considering my dad’s PSA is gradually increasing and that zytiga will fail very soon in the near future. Any insight on what we should do? Are these small increases? Should we seek other options? My dad thinks it’s completely fine because he trusts the doctor but I’m getting a weird feeling.
Zytiga not working?: So my father had... - Advanced Prostate...
Zytiga not working?

Those are still very low numbers. What is causing you needless anxiety is the type of PSA test they are giving him. A conventional PSA test has the 0.1 as the lowest level. There is nothing you would do differently until the PSA gets much higher - around 2.0.
I understand that but whats making me worried is the doubling time. What happens if in two months it rises to 0.06 or 0.07? Wouldn’t that indicate something is wrong regardless of the numbers?
There is no such thing as a doubling time for PSAs below 0.1 - it is invalid. As I said, there is nothing you would do differently until the PSA reaches about 2.0 and there is evidence of new/bigger metastases on scans. Ask for a less sensitive PSA test next time.
So in that case do we just have to wait until the PSA reaches 1 or 2 to then consider new treatment? It just doesn’t make sense to me how doubling time is not considered when PSA is under 0.1 even though it is increasing. Why not take a course of action earlier if we see it increasing?
Relax, everything is fine. Your fathers Zytiga may be effective for years.

Haha thank you, it’s the doubling time that is worrying me.
If you double 0, it's still 0.
That's what you are looking at. It's not significant until it gets above 1 or 2, then you can start looking at doubling.

Follow up-question: is it the same with the cancers that produces low PSA?
Again, relax, have a chocolate bar or 2. Right now your father is in prostate cancer heaven. I would jump for joy if my psa increased by 0.01 in a month. If you must stress out, worry about your internet service going out for a couple of days. I go to the cancer center at the University of Michigan hospital. It is one of two centers in Michigan designated as a center of excellence cancer treatment location. The lowest they record psa wise is <0.1. In other words my psa could be 0.08 and I wouldn't know nor do they care.

Yeah I completely understand that but it’s just I’ve seen from previous posts that if PSA rises consecutively it should indicate a problem. But again, all of you are way more knowledgeable than I am.
Half knowledge is worse than total ignorance. There is no valueless information. There are incapable readers. Give you an example: Police authorities keep records of the electrical network mains frequency for forensic purposes. Mains frequency swings around it's nominal value (50 Hz in EU, 60 Hz in NA) all the time thus creating a time stamp signature. Using this database that goes at least 2 decades back they can check the authenticity of audio and video recordings look for time discontinuities or edit points and such. The information is there waiting to be exploited by the competent reader.

I did not know that. I may be in real trouble.
Why, are you involved in any way in obscure businesses?
In case you are, next time use battery powered electronic equipment and only shoot under natural light because they can extract the signature from the in-vision flicker caused by electrical lighting and the mains hum underlying audio. They can also check the consistency of audio vs vision tracks by the same methodology.

In previous posts you might have seen some from people who have had prostatectomies (surgery to remove the prostate) and are looking at very low PSA levels. This is the one case where very low PSA values are significant when considering additional treatment with radiation. Decisions are typically made between PSA levels of .2 and .3, still well above the .05 levels you are talking about. But your father is NOT in this situation so his very low PSA values are not significant.
Has he had any scans or imaging tests to show if the cancer has spread? If u haven’t maybe ask to have them done so it can calm u down. And if u had and everything is still the same and good then relax! Most likely if the doctor thinks something is going south he would already request testing. Since it seems like he hasn’t. I know how u feel I’m a daughter too and my dad is everything to me so I worry too much. Sometimes as women we worry more than men. Good luck he will be fine take care of urself too.
Repulsion caused by excesive info exposure is a characteristic of ostriches. For the human race the more data the better. I would continued monthly tests. It is in the nature of the thinking spices.

It's thyme to get tested.
I only know thyme as being a herb that is good for an anti-cancer diet, plus my wife uses it when cooking irrespectively. If your phrase is some idiomatic expression, I acknowledge ignorance but also very keen in learning.

In many cases, we tend to be on a search for pathology. Wait to see the results of your Dad’s bone scan and CT body scan. As my MO says, “Don’t worry until there is data that gives us a clear need to worry ( if you must).
Hey chocalate_123
Take it easy. This is the time you should breathe easy like all the other brothers have advised here. And I sincerely hope you only stress us with your concerns of your Dad's PSA rising, don't stress him if he is feeling fine 😉 Give him his space and let him enjoy his good performance.
If I am not mistaken, you're from Sweden, and Sweden is a beautiful place. I've been there a few times for conferences in the past. In fact, I have cousins living in Norrkopping, Stockholm and Gothenburg. Take him to the ABBA museum and dance the day away. My wife and I certainly did...haha. It was really fun reliving our young days with ABBA.
Take good care and sing this out loud:
You can dance
You can jive
Having the time of your life
Ooh, see that girl
Watch that scene
Digging the dancing queen
🕺

Thank you for your lovely comment Haniff! We are actually from Vancouver BC, Canada. My family and I would love to go to Sweden though! One of the places on our bucket list!
So Chocolate... perhaps my situation will provide a reference on climbing psa and treatment. Lupron has kept my psa undetectable < .01 for several years. When not on Lupron, and after it failed about six months ago, it doubled monthly. Went like this, at 4 week intervals, except 3 weeks for the 1.56; .02, .04, .09, .13, .31, .52, .96, 1.56.Not until the .96 number would the onc start me on an AR blocker, along with the Lupron. We knew I had become castrate resistant long before, but standard of care calls for around 2.0 before changing or adding a new therapy. I talked him into starting me after the .96 reading, but when the drug was approved and the order went in it was 1.56. We checked psa again in three weeks and it was down to .66. He said that response was excellent and that it normally takes 3 to six months to hit nadir. The drug is Nubeqa, one of the newer AR blockers out. I would love to have a .01 psa rise each month! Don't worry... just calmly make plans with you oncologist for what to do when. There is nothing wrong with planning now, you may feel better ing going so, then you're ready to go when the time is right. As a final note, if he hasn't gotten genetic testing, I recommend doing so. It can open up other treatment options, especially for clinical trials.
He is undetectable at <0.1. Quit worrying and listen to his medical oncologist. To stop the worrying, he might use standard PSA testing. I once asked my medical oncologist on why he only uses standard PSA. He response was needless worrying........

Those numbers are great!!!! It’s still low. My dad was on zytiga for about a year and his number went up to 13 And doctors wanted to start him on chemotherapy the IV kind but my father didn’t want that so I heard and read about xtandi and begged the doctor to try that but they were skeptical they said since the zytiga failed xtandi wouldn’t work I insisted we try it and Praise God it’s working keeping his PSA low. Yes I know for a limited time possibly but every treatment only works for so long. He gets his shots as well his Lupron every 3 months and xgeva for his bone Mets.
Good luck I know as a daughter and helping my dad how scary it can be he’s lucky he has u looking and searching for help.
Chemo is not all that bad for most of us. I credit it with a big part of me still being here 3 years later. Sometimes the doctors know what they're talking about. Enjoy.
Hi Monte1111 that’s wonderful news for u and that it worked out great. My father is 82 and I take care of him. So every body’s body reacts differently he couldn’t handle 5 days of Radiation he was sick and hospitalized From it so I’m happy for u but like I said people can tolerate what they can tolerate. We r not all the same especially if u are older.
Thank u
Hey, CL123! Unfortunately, worry will not go ever go away with APCa. Since the trick is to be watchful without over-reacting or under-reacting, worry will always tell us that we are under-reacting to everything.
However, if you simply look at the numbers, your father is fine for now if he feels fine. In fact, I am in the midst of the very same situation - on Zytiga with numbers drifting (seemingly) upwards...but I'm in the 0.40 range. Even so, I have no apparent signs or symptoms of disease progression, and my scan is coming up in the next couple of months. It is this scan that is the real determiner - will it reveal "no radiographic progression"? I hope so!
I will be honest and say that I anticipate the ultimate failure of Zytiga, and then it's back to chemo for a reset and on to Xtandi, likely. But today, I'm good. And you should never feel weird about that.
Good luck to you and your father! - Joe M.
Sounds like good planning to me.
With or without nuts?

On my present regime of Lupron and Casodex my PSA recorded as less than .05 for three years now for past 4 months .05, .06, and .07 for past two months and my oncologist at Memorial Sloan Kettering in NYC and myself are not worried in the least and no change of therapy is anticipated until PSA reaches 2.0 or scans demonstrate progression. It’s not easy to avoid PSA testing anxiety but I wouldn’t worry with such low numbers. Is it possible that tests can be performed at the same time Of the day with the same levels of hydration just to keep circumstances constant? Best wishes and allow the Zytiga to control the disease
