<s>[INST] A friend was diagnosed with stage 4 bile duct cancer in january 2011. He's no longer able to receive chemo, is in a lot of pain which is not well-controlled with medication, has recently started having fluids build up inside his stomach which have to be drained, and most recently his kidneys have started to fail. How long might he still have left? [/INST] The average 5 year survival for stage 4 bile duct cancer is only 18% meaning out of 100 people diagnosed with stage 4 bile duct cancer only 18 people will be alive after 5 years.RegardsDR De. </s>
