Thank you all for your responses! We will talk to our oncologist about this. I did find, from a blood test last summer I think, that krasg12r, tp53, and smad4 were mentioned with "no msi high" . We'll see if there is any tissue from biopsies available for further testing.
So much to learn, and I find it so confusing. But are grateful for you taking the time to respond.
