What Is The Life Expectancy Of A Person With Stage 4 Pancreatic Cancer?

Hi. My cousin has stage 4 pancreatic cancer that is spread throughout his liver, colon, small intestines and pelvic lymph nodes now. He has an internal bleeding somewhere and was sent home to basically die. His Hematocrit and Hemaglobin last Tuesday (almost a week ago) was 6.6 and this morning was taken to the hospital due to high temperature. How much longer do you think he will survive?
