I believe that ADT will reduce PSA and impact PSMA PET scan if started prior to scan.

ADT Orgovyx initiated Jan 6 while simulation calculations for salvage radiation being computed/mapped.
Rad Onc discontinued Orgovyx 7 days later because mapping "failed" and he wanted a repeat PSMA PET scan (1st performed 6 mos prior and before RP).
Testosterone reduced from 437 prior to 41 after only 7 days.
Waited 1 month for repeat PSMA PET (no change from 1st scan); re-started Orgovyx next day; new simulation w/ balloon (joy to the world); and salvage IMRT a month later.

Not sure this is helpful; point being that ADT can skew PSMA PET scan results (I think).

Happy 4th of July to everyone. May we all enjoy today and many more.
