A case of bronchogenic cyst with high production of antigen CA 19–9
Cancer, 1989A 35-year-old man was hospitalized with complaints of retrosternal pain and high fever. A chest radiograph showed a large round mass in the mediastinum. Of the several tumor markers in the serum tested, only CA 19-9 was elevated. Thoracotomy revealed a cystic mass with purulent hemorrhagic materials.

The serum carbohydrate antigenic determinant (CA 19-9) was assayed in patients with various diseases, and it provides excellent sensitivity for adenocarcinoma of the pancreas (25/27, 93%), while only 4% (2/54) of the patients with benign diseases and none of the 40 healthy subjects showed elevated CA 19-9 concentrations over 37 units/ml as upper normal

Vorkommen der tumorassoziierten Antigene CA 50 und CA 19-9 in Endometriumkarzinomen
Archives of Gynecology and Obstetrics, 1993Das tumorassoziierte Antigen CA 19-9 entspricht dem sialysierten Lewisa Blutgrup- penantigen. Das Antigen CA 50 setzt sich aus diesem Epitop und einer weiteren Zuckergruppe zusammen. Serumbestimmungen von CA 19-9 und CA 50 eignen sich zur Verlaufskontrolle von Pankreas- und Dickdarmkarzinomen (Nakagoe et al.; Schwenk et al.).

The Need for Assay Harmonization: Carbohydrate Antigen 19-9 (CA 19-9) Assay Example
Turkish Society of Clinical Biochemistry, 2022Amaç: CA 19-9, yüksek riskli kişilerde pankreas, safra kanalı ve kolon kanserlerinin tespiti ve takibinde diğer testlerin tamamlayıcısı olarak yaygın kullanılan bir biyobelirteçtir. CA 19-9 testinin farklı yöntemlerle ölçüm sonuçları arasında uyumsuzluklar bulunabilmektedir. Bu çalışmanın amacı CA 19-9 testinin harmonizasyon problemini ortaya koymaktır.

This tumour-associated antigen is a high molecular weight mucin epitope expression is defined by a homologous monoclonal antibody system — the CA 19-9 antibody The antigenic epitope represents a sialylated Lewisa blood group pentasaccharide and, as such, is similar to that detected by some other monocloncal antibody systems.

CA 19–9, GICA (Gastrointestinal Cancer Antigen)
1992Following the detection and clinical exploitation of alphafetoprotein (AFP), calcinoembryonic antigen (CEA), and human chorionic genadotropin (HCG) as first and basic tumor markers, the discovery of blood group-related carbohydrate structures on glycoproteins and glycolipids as indicators of malignancy has opened a wide array of scientific and clinical

[Carbohydrate antigen CA 19-9: value in pancreatic pathology].
Gastroenterologie clinique et biologique, 1986In order to determine the diagnostic usefulness of the dosage of carbohydrate antigen (CA 19-9) serum levels in pancreatic diseases, 38 patients with pancreatic lesions proved at laparotomy were studied. Pancreatic lesions were classified into two groups: a) group I: pancreatic adenocarcinoma (17 cases) b) group II: benign pancreatic diseases (21 cases)

Serum carbohydrate antigen (CA) 19-9 as a prognostic factor in cholangiocarcinoma: A meta-analysis
Frontiers of Medicine in China, 2010This study was performed to determine the prognostic role of preoperative serum carbohydrate antigen (CA) 19-9 levels in the survival of patients with cholangiocarcinoma. Articles published up to June 1(st), 2010 that evaluated preoperative CA19-9 levels and the prognosis of cholangiocarcinoma were collected for meta-analysis.
