There is obviously still cancer there, but unlikely to be in the prostate bed (because it's unlikely to be in a target area of the radiotherapy).
I think you need to push for an urgent oncology appointment, with a doubling time of under 2 months.
I would try to get a PSMA PET scan done to find it (before starting hormone therapy). If it's just a few small points, it may still be treatable with something like SBRT/Cyberknife (fine beamed radiotherapy), with a curative intent, and I wouldn't want to miss that opportunity.
If he does go onto hormone therapy without a scan, he will meet the criteria for newly approved Darolutamide (PSA of at least 2 and doubling time under 10 months and no known mets) by January and should ask about having that too.
If a scan finds mets which can't be treated, he would probably be eligible for Enzalutamide under the coronavirus rules just at the moment (but not in normal circumsances).
