I lived in the greater cinci area for ~12 yrs. Had a friend that was diagnosed with early stage colon cancer in his 20's (~18 yrs ago- he's fine!) and he went to UC medical center; same with another close friend of mine who had throat cancer (again, 15+ yrs ago). Both had great experiences.. UC is a teaching hospital/center and their doctors should all be up on everything new. I personally would stick with them over anyone else/other group in the Cinci area- but see what your primary care doctor thinks and perhaps your GI doctor, even if you have reservations about them.
If I was in your position I would go to UC first and probably also have a second opinion at Ohio state (or even Cleveland clinic) - OSU is not too far really (my surgery was 2 hrs away) and it is a great cancer center. You really want the best surgeon (board certified colorectal surgeon as mentioned) you can find and also be comfortable with and the team approach at the major centers like OSU/UC is great. I suspect UC should be fine though, but if you did go to OSU for surgery, etc. you could still get things like radiation therapy, if needed, locally.
