Welcome Kate.

These printed ratings are similar to college ratings. At some point it becomes bragging rights to some extent. Personally, as long as you are being seen at a well respected facility that uses a team approach and tumor board, factors such as how you personally feel about the team and level of trust and ability to communicate are more important that being 3rd or 7th or even 15th place.

Some very excellent facilities don't rank since they are not teaching or research affiliated to some university. I think this distinction makes a big difference for rare, unusual, and new treatments and trails. If you have a more "routine" sort of cancer, I'd go with the team that listens the best and taking the time to really perform according to your specific situation.

Good luck
Don
