Lisa,
It sure sounds (based solely on your post) that he may have been severely under-diagnosed back when they decided to do the RC. The answers to Pat's questions would give an indication to that although I don't know that the answer helps anything in his current situation.
Based on the extent of the spread, it is not good news at all. I'd suggest the best thing is to get to the top bladder cancer place in the country. Once you say where he is located, Pat knows all the best docs in the country.
Your question is a good one and a very hard one. Only a top bladder cancer doctor can really answer it though (in my opinion). It is a question of what treatment, if any, is going to be worth it in terms of his quality of life and if it will really help him. It could be that it is or it could be that palliative care is now the best plan.
My thoughts are with you and your family. This is a really tough situation and I just don't know the right answer. I think there may not be a right answer. Maybe its just going to come down to what's the best answer. I would suggest being VERY direct with the doctor on your question though. Some may just keep treating and treating because they think that's what he wants. He may not want that.
