68Ga-PSMA-11 PET/CT scan again. I forgot the prerequisites for qualifying.

It has been a long two and a half years since my first 68Ga-PSMA-11 PET Scan. That one i was a part of a clinical trial @ IU School of Medicine Urology.

Status: I've been on only 250mg of Abiraterone daily, prednisone 5mg and stopped Lupron Depot injects last June 2021. August 2019 PSA 14.393...

Dec 2019 PSA 1.100 ... Aug 2021 PSA 0.126 ... Dec 2021 PSA 0.156 and this years PSA Feb 24th 0.300 ..

So Dec '2021 till Feb 2022 my PSA doubled. I am not on Lupron and only one Abiraterone tab daily due to cardiac toxicity and arrhythmia issues. Next PSA and Testosterone will be May 15th. Oh my T-levels are <3.0 I'm expecting my PSA to take a big jump in May. What qualifies a level or staging criteria for 68Ga-PSMA-11 PET scan??

THanks,

Depot Doug

I think generally it is approved for use when your medical team has determined your PCa has recurred. That could be rising PSA as one clinical indicator. Here's a link to a video discussing it. - urotoday.com/transformative...

Brilliant response. Just what i needed to justify my 2nd 68Ga/PSMA-11 PET Scan after my next PSA Jump.Thanks so much Hawk56!

Yeh my 1st PSMA 08/10/2019 was so definitive abd conclusive.

I’ve now got the IU Urology head of Imaging scans(PSMA included) on my team. It makes me breath easier to know i’ve got the right treatment detection mechanisms…

Yes, a repeat PSMA scan now with a PSA of 0.3 will be your most sensitive tool to see if there is visible progression. That will inform adequacy of treatment or if need for a change. That is an approved indication for the scan. They might have switched to Pylarify from 68Ga which slightly complicates comparison but is not really a problem.

[depotdoug in reply to MateoBeach]

That's great to hear. Especially since last Wed's visit with my super urologist I've had since 2016 decided to refer me to IU Health's Urology head of Cancer scanning procedures. I have a F/U appt with Dr. Bahler 2 June. That's just a week after my Oncologist-NP visit and my newest PSA's and T-Levels results.

One comment: My newest Urologist ( I know him a bit) is with a different health system than my new Oncologist. But as far as I'm concerned I can choose the decisions of my PCa health paths. For example: Urologist decides to do a repeat 68Ga-PSMA-11 or Pylarify PET scan in June, and my Oncologist (different health system) disagrees; I'm the deciding person on my cancer care detection and treatments.

Thanks MateoBeach

Thank you so much. You really solidified my decision coming up in late May.PSMA PET will be the test that I will ask, insist to get.

If my new cancer health system med oncologist differs on that(my) choice of 68Ga-PSMA-11 PET scan, I’m going to have it done by my newest Urologist, who is head of ancer imaginging @ IU Health Systms Medicine !

I see him Dr. Bahler June 2nd.

You just made my day Abhishek_Roy

Thanks.
