[|Human|] Hi, My mam has cholangiocarcinoma stage 4, spread to gall bladder and liver. She is 84 years. Not receiving any treatment, only palliative care. She vomitted bile today and was very weak after. Appetite is very poor. I am worrried, have we much time left with her? Thanks
[|AI|]  Thanks for your question on Chat Doctor. Stage 4 cholangiocarcinoma is inoperable cancer and prognosis is not good. Overall life expectancy is less than 14-15 months. Old age and symptoms of vomiting with weakness, decrease oral intake Carnot a good sign for prognosis. In my opinion you mom is having poor prognosis and life expectancy is less than 7-8 months. If vomiting persists than start TPN (Total parenteral Nutrition) for palliative care.
