CA 19-9 is a tumor-associated antigen that is reactive with an antibody that was produced in response to immunization with a human colon cancer cell line.CA 19-9 has also been shown to be a more sensitive and specific marker of pancreatic cancer than other serologic markers. Very little of the antigen is found in the blood of normal patients or those with benign disorders, but most patients with pancreatic cancer have elevated levels of CA19-9.
