@krisohlson wish I could help you out but. You could apply to some larger cancer clinics or Mayo Clinic. There is a good one down near LA but the name escapes me.
Locally or even in the Oregon and Washington state area, nothing comes to mind.
Many of the university hospitals are to me less impressive than most people believe because after all, they are either teaching or learning rather than focusing on the patient.
Places like Mayo, Cleveland Clinic, John’s Hopkins put the patient first and work as a team to the patient’s best possible health.
It seems you have not given up whilst your doctors already have. That’s not good for you or them. I wish you well and stay in the battle.
