More information on Intrahepatic Cholangiocarcinoma please

Hi There, I am so glad I have found this site which has helped me try to understand a bit more about this cancer. My sister was diagnosed in August with Intrahepatic Cholangiocarcinoma and was a candidate for resection with the intention of cure. She underwent surgery in August which they hoped would be successful but to make sure was advised to undergo 6 cycles of GEM/CIS. 2 Weeks before Christmas she had an MRI which showed spots on the liver which they suspect is secondary. We are all devastated and shocked by this and wanted to reach out to see what else we can do. I have read so much and learned so much from you all but need to know if there is anything else we can do. She has another MRI in February which will indicate whether the GEM CIS is working and next stage will be to see if she eligible for clinical trials. We are based in the UK are we have been told that this is such a rare cancer. My sister is a 46 year old single mother and has a 15 year old child so if there is anything we can find out I would be so grateful..
