My husband’s PSA continues to rise yet his PSMA scans are all clear.
His last PSMA was late October with a PSA of 4.7
His PSA today was 6.5
It seems I have noted on this forum some other type scans should be done besides PSMA.
His ALK PHOSPHATE is 85 (normal)
Calcium levels all normal.
Thanks for any information you might lend!
He may have PSMA negative tumor. An axumin scan or a cholin pet/ct can detect this type of tumor. With a value of 6.5 his PSA level is too low for an FDG PET/CT, which could be used also.
Axumin would? My RO seemed to say Axumin uses same mechanism as PSMA scan; the difference is degree of quality. Is that an oversimplification? That's what I understood him to say. I've only had Axumins the last four years and we discussed this recently in the context of a complementary scan for PSMA.
I was refering to this report by Misha Beltran, who found that fluciclovine PET (Axumin) can detect PSMA suppressed tumor. urotoday.com/video-lectures...
A Choline PET scan may help.
On the point of at what PSA that psma scans can show a tumor, my own experience is that they did not until I reached a PSA of 8.9. Just one data point (the one that mattered the most to me).Jeff
What treatment did you do at that point?
We did SBRT to the single met. Still waiting to see result.Jeff
My PSA was around 8 when an FDG picked up 4 mets. Two PSMA scans were clear when my PSA was 2 and then 4..
See if this helps...PSMA PET is a good scan; amazing it will not find your PCa...

I also include a Mapping of testing that may help find something else that could help...

Good luck...Rick
how sensitive is the PSMA scan?
Low PSA and PSMA scan 
Baseline PSMA-Pet scan?
Why the need for an FDG scan in addition to a PSMA scan?
