Background

Carbohydrate Antigen 19-9 (CA 19-9), a tetrasaccharide carbohydrate, is extensively employed in the realm of pancreatic pathology. It possesses a structure that incorporates a transmembrane protein scaffold and extensively glycosylated extracellular oligosaccharide chains.

The CA 19-9 is expressed in the ductal cells of the pancreas/biliary system or the epithelial cells of the stomach, uterus, and salivary glands. Its production is contingent upon 1,4-fucosyltransferase, a product of the Lewis gene. Although there have been reports of overexpression of CA 19-9 across a spectrum of gastrointestinal and extragastrointestinal diseases, its primary application is fundamentally as a tumor marker for pancreatic ductal adenocarcinoma. It serves as a robust surrogate index for overall tumor burden or tumor activity.
