If the PSMA PET scan didn’t show anything, how will they know where to target the radiation? (With a 0.10 PSA, PSMA PET scans will miss prostate cancers 70%+ of the time.)

Did your PSMA PET scan result in any reported SUVmax scores?

“limited sensitivity in assessing the prostatectomy bed because of early urinary excretion of radiopharmaceutical” makes sense because the radiotracer being excreted hides anything else nearby that might show up under the scan.

Dr. Kwon (of Mayo Clinic) indicates that only 1/3 of men who have recurrence following prostatectomy have recurrence only in the prostate bed, and that they should not get salvage radiation there unless they’re absolutely certain of the location of recurrence. He says to first confirm where the recurrence is. (See Dr. Kwon’s presentation about recurrence: https://youtu.be/Q2joD360_pI)
