I'm getting a PSMA PET scan at UCLA next week, so I can see if Lu PSMA therapy will be effective. My understanding is that this is a theranostic treatment, the scan confirms PSMA expression, which confirms that the Lu PSMA will have a site to bind to. I thought that the PSMA PET scan was a required step prior to treatment. Posts on the site talk about local doctors, and other countries administering Lu PSMA treatment, seemingly without scans.
There are two tracer drugs available for the PSMA PET scan, Ga 68 PSMA-11 and Pylarify (piflufolastat F 18). Ga 68 PSMA-11 was approved last December only for use at UCLA and UCSF. Pylarify was approved in May for other sites, and should be more widely distributed due to the longer half life of F 18.
Are those of you that are getting Lu PSMA therapy at other locations required to get PSMA PET scans? What I read of the treatments in Germany, they used scintography to measure the update of LU PSMA, not PET SCANS with a radioactive tracer prior to treatment.
