Enhanced discrimination of malignant from benign pancreatic disease by measuring the CA 19-9 antigen on specific protein carriers. [PDF]
PLoS ONE, 2011 The CA 19-9 assay detects a carbohydrate antigen on multiple protein carriers, some of which may be preferential carriers of the antigen in cancer. We tested the hypothesis that the measurement of the CA 19-9 antigen on individual proteins could improve ...

Diagnostic Value of CA 19-9 and Carcinoembryonic Antigen for Pancreatic Cancer: A Meta-Analysis
Gastroenterology Research and Practice, 2018 Background. CA 19-9 and carcinoembryonic antigen (CEA) are widely used for the diagnosis of pancreatic cancer. The purpose of the present study was to compare the diagnostic value of CA 19-9 with CEA for pancreatic cancer. Methods.

The prognostic value of postoperative tumor marker conversion for gastric cancer [PDF]
Korean Journal of Clinical Oncology, 2020 Purpose Preoperative positivity of serum tumor markers has been associated with poor long-term survival among patients with gastric cancer. However, there have been a considerable number of patients who have experienced a normalization of tumor markers ...

CA 19-9 and carcinoembryonic antigen in pancreatic cancer diagnosis [PDF]
Cancer, 1986 CA 19-9 (Centocor, Malvern, PA) and carcinoembryonic antigen (CEA), two recently developed immunoradiometric assays utilizing monoclonal antibodies, were evaluated in the sera of 139 subjects in order to assay their individual and combined value in pancreatic cancer diagnosis and to assess the influence of jaundice.

CA 19-9 in Ovarian Immature Teratoma- A Potential Tumour Marker or A Masquerade? [PDF]
Journal of Clinical and Diagnostic Research, 2022 Carbohydrate antigen 19-9, also known as Cancer Antigen (CA 19-9) is a tumour marker found elevated in certain ovarian tumours. Although, reports of its association with mature teratoma are considerable, little is mentioned about its association with ...

Prognostic Value of Carcinoembryonic Antigen (CEA) and Carbohydrate Antigen 19-9 (CA 19-9) in Gallbladder Cancer; 65 IU/mL of CA 19-9 Is the New Cut-Off Value for Prognosis [PDF]
Cancers, 2021 Due to the lack of appropriate tumor markers with optimal cut-off values to predict the prognosis of gallbladder cancer (GBC), this study aimed to demonstrate the relationship between prognosis and the levels of carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA 19-9), and to determine optimal thresholds.

Elevated Carbohydrate Antigen 19-9 (CA 19-9) in Patients with Echinococcus Infection [PDF]
Clinical Chemistry and Laboratory Medicine, 2001 The carbohydrate antigen 19-9 (CA 19-9), a determinant (sialylated lacto-N-fucopentaose 119) of a circulating oligosaccharide antigen, is a frequently used tumor marker. Echinococcus spp. infects humans throughout the world and may be able to synthesize closely related molecules which could interfere with the measurement and interpretation of CA 19-9 ...
