It must have been so hard to see your brother suffer, and believe it was preventable. My heart goes out to you.
I know CCCs are the holy grail around here, but I am the wee small voice in the corner saying, "...usually best....not always." I think it's dangerous to assume that CCCs invariably provide better care, and close-minded to conclude that no non-CCC institution can ever be as good as a CCC.
The non-CCC I am using is a large, academic and research institution that treats HNC all day long, has a dedicated HNC team, the same technology as the CCC, and some major talent assigned to my case.
Many, many people don't have the luxury of a CCC due to distance, insurance, logistics, disposition, you name it. Please don't make them feel anxious about their option. Consider that 16 U.S. states do not even have a CCC. In my case, going to the CCC would mean foregoing chemo. Maybe some will think that if that's what a CCC recommends, that's what I should do.
