I've been following your writing since you started--and even commented a few times. It's good that you're seeking good quality professional opinions--and reading here and other places on your own. Education about what is happening is a good thing.
That being said, going down into the rabbit hole of wanting certainty and guarantees is very, very risky. It does sound as if you want a guarantee that you will have complete cancer control, not matter what the current or future cost might be. You are unfavorable intermediate risk--the important word there, I think, is intermediate. With intermediate risk, you do not need to throw the kitchen sink at it, hoping that something will work. By doing that, you are significantly increasing your potential side effect profile, and risking your future quality of life to minimal gain of cancer control.
I can't tell you what to do, and that is not my intention. I'd only suggest you try to put down, clearly, what your risk/benefit scale looks like. How much future risk are you willing to accept for incremental improvements in benefits?
Well Said Sir.. I have be careful not to "chase my own tail" as I'm learning, Over treatment is a concern too.. thanks Ed
