Sounds like there needs to be a lot more discussion with his oncologist.
I can't imagine being on chemo for the rest of my life. Chemo does enough damage that it seems an impractical statement. Blood counts get messed up, kidneys get damaged, side effects get progressively worse, etc.
I can see maintenance chemo going on and on but not the full on stuff.
What is he on?
The doc needs to give you answers to your questions. With chemo, there are just way too many variables for us here to answer.
Sorry you haven't gotten the answers yet but keep pushing.
