Target Information
Mucin glycoprotein is a Sialyl Lewis A structure synthesized from type 1 blood group precursor chains and is present in individuals expressing the Lewis A and/or Lewis B blood group antigens.
In normal tissues, sialyl Lewis A antigen is found in ductal epithelium of the breast, kidney, salivary gland, and sweat glands.
Its expression is greatly enhanced in serum and in most tumor cells of gastrointestinal (GI) carcinomas, including adenocarcinomas of the stomach, intestine, and pancreas.
Preoperative elevated CA19-9 levels in stage I pancreatic carcinoma patients decrease to normal values following surgery. When used serially, CA19-9 can predict recurrence of disease prior to radiographic or clinical findings.
