The best list of institutions, listed by survival rates and lots of other qualifiers, is put out by US News and updated on their web site every 6 months. Please do not pick an institution based on geography. The list is at this link, then under medical databases, then the link that says best hospitals. Please read the note below it, as their site has a bad link in it that they have not fixed in 60 days since I first noticed it and notified them.
