Description:

Cancer Antigen 19-9 (CA19-9) is the sialylated form of Lewis antigenA. It is a tetrasaccharide with the sequence Neu5Acα2-3Galβ1-3[Fucα1-4]GlcNAcβ. It is a serum tumor marker elevated in blood of patients with carcinoma of the gastro-intestinal tract, primarily used to distinguish pancreatic cancer from pancreatitis. CA 19-9 is not sufficiently specific for use as a cancer screening test; however, the specificity for pancreatic cancer increases with increasing levels (high levels showing a specificity of >97% for tumor presence).
