Hi, My Father Was Diagnosed With Adenocarcinoma Poorly Differentiated And

Hi, my father was diagnosed with adenocarcinoma poorly differentiated and also cholangiocarcinoma this Jan. Doctors ruled out any treatment except palliative care for his age of 81 years.
On Saturday, he vomitted black liquid twice around 1.5 ltrs
He is in the ICU now. Doctors say he is still bleeding internally. His skin colour is also pale. There is a lot of cough inside. And he seems to have a temperature(not as in fever) and throat pain. Doctors r not sure if he can solid foods now.
Can u tell me how advanced is his condition? How much time can we expect for his life?
Thanks
Nandini
