If you don't mind, where are you, in which state? Of all the two consults you have made, which one was the more important centre you went?
Do you know if the doctors have ran any genetic testing over the tumor --things like KRAS, BRAF, or maybe were you told if he is MSS or MSI-high? It doesn't matter if you don't know right now, I'm just asking in case you have some inform there with those acronyms.
I read in other thread that he has mets in liver and lungs, plus the primary --colon--. Is that correct, is there disease somewhere else?
As others have said, each case is unique and even in difficult cases, remarkable responses are possible, that allow surgeries, and other treatments. Treatment is changing everyday, with more agents, like immunotherapies, that start to show results when it seemed impossible. So, yes... justbreath
. Your screename is a very wise one.
