Any advice on caring for my wife who was just diagnosed with cancer?

Six hours is a long way and a long drive. My wife had ovarian cancer, and we live 45 minutes away from where she got treatment. We were only a little late once for her infusion because of a traffic jam. We have been lucky. I would consider getting closer to the treatment site. If you have to go to the emergency room, it would sure help to be closer. We went to the ER three times during the first few treatments, because the chemo caused blood pressure problems. Until she saw our PCP, a cardiologist and got on two different meds for that, things were unstable. You never know what side effects will arise of the many possible side effects that you get informed about by the oncology staff. There will probably be radiation therapy wilth colorectal cancer, and I don't know all the different things that can happen with it. My niece's husband had that with both radiation and chemotherapy, but they were close by the treatment site. He pulled through good so far. We'll all pray for the best for you.
