How long does your oncologist have you on ADT?
I had surgery in March 2020. I was undetectable for 3 years, then started to see some PSA. .05.....06 ... Eventually climbed to .25 in Feb/2025, which triggered follow up treatment, starting in Late March 2025. Orgovyx for 6 weeks then 25 radiation treatments which ended 6/25/25. I am scheduled for ADT for 6 months,ending around Oct .1. My question is- is 6 months the norm?

That's a good point. As far as I understand, the reason castrate resistance sometimes emerges on ADT is that the castrate-resistant cells (if any) are the only ones that can multiply, so eventually they reach a point that's detectable.
If you weren't on ADT, both the castrate-sensitive *and* castrate-resistant cells would be multiplying, so you'd have more cancer sooner, possibly in vital organs.
ADT buys you time, even if castrate resistance does eventually emerge. You're forcing the cancer to restart from a much lower point.
How long was your husband castrate sensitive. Or how long did it take for your husbands cancer to become resistant to ADT.
Sorry but I don’t remember. He was first diagnosed in 2005 and had his first recurrence in 2011, which is when we first saw Dr Kwon at Mayo.
Actually, you become castrate resistant and ADT no longer keeps your PSA down, Even though you are castrate resistant, not every cell is castrate resistant as you mentioned.
You then begin an ARSI Because they are capable of keeping the PSA down, even if castrate resistant.
I’ve been castrate resistant for six years, If I reduce my main ARSI drug, my PSA rises immediately. I was on Zytiga for 2 1/2 years. I tried reducing from four pills to three to see if it would help with the brain fog. My PSA went from .2 to 1 in 18 days because I had reduced the ARSI.
I stopped taking Orgovyx For eight months. Darolutamide Kept my PSA undetectable the whole time. That’s because Darolutamide works even if there is testosterone. (Other lutamides too).
I did not say every cell is castrate resistant. For many men who started their metastatic cancer treatment 6, 7, or even 8 years ago. The treatments was different. The medical community would start you on Casodex for 30 days and then start you on ADT. At some point resistance would set in and they would offer chemo. PSA would go down and then start to rise. Then they would start you on an ARSI like Xtandi and the ARSI would keep the cancer under control for many years - hopefully.
Now - triplet therapy has replaced doublet for high volume metastatic prostate cancer. You get all the treatments up front and they are hoping for longer deep remission.
I was told by my doctor if I ever started to become resistant they would not stop ADT or Darolutamide. I believe Darolutamide is a miracle drug and is superior to the other ARSI's.
❝I believe Darolutamide is a miracle drug❞
Yes, all of the -lutamides are pretty amazing and work similarly, with small differences in possible side-effects.
That's not to say older treatments like Abiraterone can't also be effective, but studies like TITAN (Apalutamide) and ARASENS (Darolutamide) and ARCHES (Enzalutamide) have shown stunning improvements from starting an ARSI at the same time as ADT for metastatic castrate-sensitive prostate cancer, instead of waiting for castrate-resistance to set in. And as a bonus, the -lutamides don't require you to take a steroid with them like Abireraterone does.
Unfortunately, sometimes Abireraterone is all private insurance will pay for. 😕
Casodex is only required for two weeks before Lupron (etc.). Of course, if you start with Orgovyx you can skip Casodex.
They do not offer chemo if somebody is just castrate resistant. I have never been offered chemo because it is generally inappropriate if you don’t have metastasis. I have had PC for 15 years and castrate resistant for 6. My one spinal metastasis was zapped with SBRT, appeared 2 years ago.
I’ve heard from many people that have had triplet therapy and in almost every case it’s because they had multiple metastases found upon diagnosis or after a drug holiday. In cases where there are n five or fewer metastasis, they usually like to use SBRT rather than chemo right away.
When somebody becomes castrate resistant, they are almost always given an ARSI, NCCN calls for it.. Those include Zytiga, apalutamide, Enzalutamide, and Darolutamide.
I like Darolutamide a lot, It has worked quite well for me And many other people, I know.
Apalutamide has worked quite well for some people and is now involved in a study where people who are castrate sensitive stay on it, and it prevents them from becoming castrate resistant. It’s a study so no final results are available yet. Maybe Darolutamide works the same!
You said
‘I did not say every cell is castrate resistant.”
If you review what I said, you will see I said “ not every cell is castrate resistant as you mentioned.”
❝Apalutamide has worked quite well for some people and is now involved in a study where people who are castrate sensitive stay on it, and it prevents them from becoming castrate resistant.❞
Absolutely right! The TITAN trial completed in 2020 and published in 2021, just before I was diagnosed later that year (luckily for me my onco team was following it). The trial focussed on ADT+Apalutamide to treat metastatic castrate-sensitive prostate cancer (mCSPC) before it became castrate-resistant, and the results were so dramatic (both for slowing progression and increasing overall survival) that they were forced to unblind the trial early and allow the control group the option to start taking Apalutamide as well instead of placebo.
The trial failed to reach median overall survival — after 4½ years, over half the experimental group was still alive, and a large minority were still castrate-sensitive, despite the fact that a de-novo diagnosis wasn't required, so many participants had already had mCSPC for years before the study started.
Since then, other studies have shown similar results for Enzalutamide and Darolutamide with mCSPC. It's rapidly becoming standard of care to add a -lutamide to ADT immediately for mCSPC, instead of "saving it for later" if/when castrate resistance happens.
Your posts are very informative. You seem very knowledgeable. Is this from being an informed patient?
I have had PC for 15 years. I’ve had surgery and then radiation and then two more recurrences. I’ve been on Lupron and Orgovyx, Zytiga and Darolutamide.
For about the last four years, I have attended weekly, advanced prostate cancer online meetings at Ancan.org. I hear from people every week that talk about their new case of advanced prostate cancer or an old case that is being managed. I hear about all different types of treatments being given.
I also attend prostate cancer UCSF online meetings once a month and a CSC Meeting twice a month. And in those meetings, lots of new people discussing their cases and treatments they’ve had or are planning to have.
I am a mentor with Imerman Angels And I help people who are having issues adjusting to prostate cancer.
I attend many webinars, Usually more than one a week, Discussing treatment and other issues related to prostate cancer. Going to PCRI meetings can Provide an incredible amount of information. You can check them out on YouTube if you really wanna get an education.
So I’ve spent a lot of time collecting information because I need to know where I can go with my next step.
