I have to agree with Tom, Mayo is a great place for the consult, and ongoing treatment if you can make that work.
You also mentioned that she’s not a match for any of the targeted drugs. Without a biopsy, how do they know, did they do a liquid biopsy (blood)? The liquid biopsy will pick up on any tumor cells that are being shed into the blood stream, which works better when the tumors are larger.
Best of luck to you, hoping that you find the answers that you need. Please keep us posted. Lisa
