I am Sandie and I also have cc and live in the UK. Like your daughter I had a resection followed by chemo and radio. The chemo may not be easy but it may not be too tough either, as we each react differently. If your daughter stays positive and finds lots to laugh about she will get through it. There are lots of coping strategies I discovered to help with side effects and also to help with talking to people about progress whilst on chemo. Like your daughter, I saw Prof Valle for a second opinion and he really is excellent and honest. My advice would be to stay in touch with Helen at AMMF who has an amazing knowledge and network of people that can offer advice. (AMMF also have a discussion on board on their site). Also to use these forums to talk to others who may have experienced similar side effects to the ones your daughter may go through.
Take care and I wish your daughter and yourself the best.
