[|Human|] hello. my father has cancer of the oesophagus and the cancer has spread to the lymph nodes and liver as well. plus hes not eating and is having steroids and build up drinks to help him. I dont want to lose him but i need to know how long do u think he has to live?
[|AI|]  Thanks for your question on Chat Doctor. I can understand your fathers situation and problem. Esophagus cancer is very notorious in spread. And it is not having good prognosis. Your father is having liver metastasis, this means he is having end stage (stage 4) Esophagus cancer. Stage 4 Esophagus cancer is having life expectancy less than 1 year. Five year survival rate is less than 15-20%. The main reason is decreased oral intake. Cancer in esophagus does not allow food or liquids to pass, so patient is malnourished, immunocompromised and very, very weak. So in your fathers' case prognosis is very bad.
