My AI gave references for the suggested ranges, which, in the main, vary from 1 to 2 years' worth of data. My R.O. also gave me her figure a couple of readings ago, and it was also >12 months. I just needed some confidence that it's unlikely I'll go much over 0.3 in the next two months--we're waiting for that, regardless of the time that takes. BTW, I believe the MSK calculator assumes a log‑linear rise.

DjinTonic.....not trying to be difficult, but I re-punched in all your numbers and doubling time from MSKCC is 10.9 months.
Even if you just use the 2 values from 8/4/2025 and 12/22/2025 it returns 11 months.
not sure where you are getting 16.6 months....anyway makes no difference.
My brother PSA hit .42 and PSMA scan lit up his prostate bed and a spot on his hip....the biopsy of his hip was negative, but with a disclaimer that they are hard to hit and they could have missed the spot....they then said they would have radiated the spot anyway.....I asked then why bother with the biopsy.....thanks for nothing I told them.

Djin - Your rate of increase per day actually decreased significantly from the previous measurements. 11/10/25 is actually the odd one to me. This makes me think doubling time would be a waste of computational effort. I like to think you have a bunch of 0.2's that may become 0.3's someday and probably not tomorrow.

Hopefully not to ad nauseam, again sharing my different diagnostic and treatment path. Prior to my RP ten years ago I learned to do not give this beast time and obscurity. So eight years ago this week I headed to Radboud UMC, Nijmegen, Netherlands, for Ga68 PMSA PET (they already had solid experience eight years ago), and the 'even better' Ferrotran nanoparticle MRI. That comparative imaging was done at uPSA 0.093, nine months after unsuccessful SRT to prostate bed (shot blind and missed some); pre SRT PSA was 0.113 and post treatment nadir was 0.075.
Although the PSMA PET was clear the Ferrotran MRI identified multiple cancerous pelvic lymph nodes. Six total were confirmed by salvage pelvic lymph node surgery including para-aortic node, using frozen section pathology method at OLV Hospital, Aalst, Belgium. Post SePLND nadir was <0.010. A few years later I learned Kwon supports SePLND and the Mayo offers them on a limited basis, but unfortunately the Ferrotran MRI is still on restricted availability in Europe. I continue to wonder how the Ferrotran MRI would change things here in US; oddly it began as Combidex here in the US in the 1990's.
Today, my uPSA is holding very low stable 0.03X, no ADT. Although I am grateful beyond words I do not dismiss this lingering PSA having had RP, and continue steady watch with quarterly uPSA testing, annual comparative imaging and liquid blood biopsy testing. All the best to all of us!
Benign biopsy at 47 with PSA 20.4. Metastatic disease at 57 with PSA 10.1; otherwise excellent health and fitness. Intent is to defer ADT/CR for as long as possible and no longer give cancer time and obscurity. Treatment path: RP, salvage RT to bed, advanced imaging in Europe, salvage ePLND. Since June 2021 uPSA holding 0.03X range, still no ADT. Murray Keith Wadsworth, author, podcaster.

The only reason we were looking at doubling time was to help plan out next steps--and I wanted some degree of assurance that my PSA wasn't likely to skyrocket if I spaced out PSA testing. I think there was some miscommunication also--I and my uro were thinking that my first PSMA-PET scan would be at 0.2; however, my R.O. felt strongly that it would be negative and that it was better to wait for (at least). So I was doing PSA tests every 2 weeks for a while.
My scan should give us good information. If anything shows up, we'll treat. A more difficult decision will be what to do if nothing does: do we zap or do we wait a little longer and rescan. There are quite a few indicators that this is not metasatic disease and is behaving like indolent cancer:
pT2 with negative margins and 16 negative nodes
Low-risk Decipher score
Low (5%) tumor burden
Post-RP PSA nadir <0.010
Late onset of BCR with slow velocity
No red flags (as far as I can tell) in my Decipher Grid report, which, BTW, indicated that my cancer is susceptible to RT.
All that has to be weighed against my Gleason 9 (4+5), which put me in the high-risk group from the outset.
I'll be 78 in April, and I think that should be in the picture. Assuming my PSA will continue to rise, I do want to treat before my PSA reaches 0.5. I'm thinking that the decision will come down to: if the scan is negative, do I treat or wait and rescan at 0.4? (If you zap the fossa or fossa "plus," you don't get to re-zap the whole pelvis if pelvic nodes are later detected.)

My post RALP PSA is slowly rising (for the past year) and has just crossed the 0.10 threshold, so the doctor ordered a TRUS. He said that he'd wait to do a PSMA PET until I hit 0.20 and possibly 0.30. Presumably, that might change based upon the TRUS. He said I'd likely not start treatment until 0.30. In the meantime, I'm hanging loose (in Hawaii) and enjoying the absence of medical treatment.

Hi Patrick and thanks for joining in to the thread.
You say you've "crossed the 0.10 threshold. What was your last PSA reading?
Remember, "official" BCR is still a confirmed 0.2 and rising, because some folks do plateau. Even if treatment may be a long way off for you, I suggest you think about adding a R.O. to your team should you reach 0.2.

"official" 0.2 is a dated medical industry construct - many centers now use 0.1. Regardless, if cancer at these values how is it not at lower values?
As I share imaging at 0.093 identified multiple lumpy nodes - six confirmed cancerous by salvage pelvic lymph node surgery including para-aortic. Would it have stopped there - IDK? But at 61 not willing to wait and see. All the best to all of us.

Your Dec 25 PSA was a bit higher than anticipated, i.e. 0.242 vs 0.228. (PSADT -> 19.5 months)
Extrapolating on your future PSA count (9 weeks after last) leads to:
23 Feb 2026 -> 0.250

I learned to be mindful of cancer advancing ahead of PSA and imaging. Liquid blood biopsy testing is recognized for identifying metastasis ahead of imaging. LBB identified my metastatic melanoma ahead of imaging. A read for consideration:

My PSA became detectable (0.03) in 9/24, then slowly rose to 0.07 in 3/25, then dipped to 0.06 in 6/25, then back to 0.07 in 9/25, then jumped to 0.11 in 12/25. I am seeing the folks at UCSF Medical Center (i.e. Dr. Peter Carroll's team) and they have an RO in the loop. Per their direction, I am testing the PSA every three months.
Patrick, you are certainly in good hands.

Solid plan. Given your long slow rise, I wonder how that affects the probability of finding something? Is PSMA expression affected by rate of rise? Some men find something right away, others require a higher PSA.
The medical situation has been one of consolidation for years in the Twin Cities and probably everywhere. In contrast, the University of MN became part of a private health group, M-Health, which was a couple of merged medical organizations before the University agreement. Basically, there are no individual or small doctor groups around here anymore.

I believe it all comes down to the size of the lesion(s). Currently I think the minimum lesion size that lights up is about 4 mm, so, for example, the chances of someone with the a very low PSA like me may or may not have a positive scan depending, perhaps, on whether there is, for example, one "larger" lesion in the fossa--or smaller mets in surrounding nodes (or other tissue) that fly under the "radar."
I'll post when I have the scan results.

No, size is a second order prediction variable. The decisive one is the spatial concentration of the radiopharmaceutical. A 1 mm dense/compact tumour can attract enough of the latter such that can glow up, while a 10 mm loosely populated one can get buried into noise. The confusion originates from the image resolution of the PET scanner. Two totally different things.
