Hi Paul. Given the importance placed on his biopsy Gleason score for his treatment plan (both the RT and ADT duration), the JH review of his slides could be relevant. I would discuss the value of a Decipher Biopsy score to have some idea of his cancer's metastasis-risk bracket (low, intermediate, or high). I would be more concerned/aggressive about
a G7-8 with a high met risk than a G8-9 with a low met risk.
If a PSMA/PET scan were to show no mets, would 2 years ADT be necessary/appropriate for an 81-year-old with a heart condition? Given the PSA of 12, why not do a scan?
AFAIK, SBRT isn't routinely done on the whole pelvis (some studies
here). I think the total dose to the bowel and bladder is too large where they (unavoidably) come into the RT field. (See also the paper about
increased risk of lumbosacral spine fractures.)
Would a consult with another R.O. be helpful? I can see it being reassuring if they agree; but what do you do if they don't?--choose one? balance/average the two if that's possible? get a third opinion?
Relugolix seems like a good choice for ADT.
