Hhhhmm, it's really tough for you when it seems radical treatment is needed but the OH is simply not ready for it yet.
The thing is, I don't think you could call it active surveillance anymore if he still doesn't agree to treatment after he has had a little breathing space. AS is used to describe the proactive monitoring of a cancer to ensure it isn't progressing, and - if it does progress - to identify when a tipping point has been reached where intervention is necessary. In your case, it has progressed significantly and the moment of intervention has been reached so having no treatment from this point on isn't really AS, it is 'choosing not to have treatment'. I hope that by the time of his next review he will feel more confident in the new medical team.
How high is his PSA? I couldn't see it anywhere in your postings or profile.
