Amy Sue, In addition to the information you already got from Kanaaz and Nancy, I might add that you can call Mayo Clinic appointments (http://mayocl.in/1mtmR63) and ask if the oncologist with whom you have an appointment would talk to your brother's local doctors. Mayo Clinic experts mentor providers all over the world and will work with local physicians who maintain your care in between key appointments at Mayo for surgery or consultation and testing. While you haven't been to Mayo yet, it might be worth a try to continue chemo as suggested until his appointment in December.
