59M, cT2c, Gleason 4+3=7, PSA 7.8 prostate cancer diagnosis.



Before undergoing radiation treatment or surgery,


1) how beneficial would it be to get a PSMA PET scan to confirm if there are any metastasis nearby the prostate?


2) And is PSMA PET scan the most advanced imagining, diagnostic technology for prostate cancer as of 2021?

It depends - not all prostate cancers show up on scans anyway and different PSMA tracers are better in certain circumstances and with different PSA levels. Of the two most common tracers used here, one is better at picking up recurrence clusters at low PSA levels while the other is better at picking up clusters at the diagnostic stage. There are other PET scan tracers as well, not just PSMA - so one of the PSMA tracers may be the most advanced in the UK in your situation but in my husband's case we would probably go for something like FACB / axumin instead.
No matter how good the tracer is, it is unlikely to pick up micro-mets.

No.

Have you had a hi-res mri Scan and a template biopsy?

G-68 PET-PSMA scans, although rare in themselves, are usually only used to locate metastases following unsuccessful prostatectomies.
