All of the responses so far are reasonable to me. I am assuming the patient is Gleason 3+4 with PSA <10 ng/mL. I am wary of applying a new technology to categorize patients to older trials (i.e., T3 on mpMRI and assuming that is the same as clinical T3 prior to MRI). That said, I can't call a patien...

This is an important question and I think a lot of different answers are acceptable. I would generally SBRT patients like that without too much concern (but then I use a more aggressive SBRT dosing).

Extrapolating from Stephenson's data on post-RP recurrent and recurrence with salvage RT, ECE alone...
