Antigens are substances that cause the immune system to make a specific immune response. CA 19-9 antigens are foreign substances released by pancreatic tumor cells. CA 19-9 associated antigen levels are elevated in many patients with pancreatic cancer. It is important to note that not every patient with pancreatic cancer will have an elevated CA 19-9 level. In addition, some non-cancerous conditions can cause high CA 19-9 levels. For these reasons, the CA 19-9 test cannot be used as a diagnostic or screening test for pancreatic cancer. Changes in CA 19-9 levels help determine if the tumor is growing, remaining stable or getting smaller. This test helps doctors decide if treatment should be changed or if additional tests or scans are necessary.
