Can a person live up to 5 years does it make a difference if you were diagnosed stage iv colon cancer than if were stage iii but now hav a liver met?

No diff: The prognosis of someone diagnosed today with a liver metastasis of a colon cancer diagnosed a few years ago is not different from that of someone presenting today with newly diagnosed liver mets and primary colon cancer. Five year survival is not the rule, unfortunately, but I have seen many patients whose life exceeded five years after such a diagnosis. Treatment is improving rapidly.
