Title: IMMULITE OM-MA assay: a useful diagnostic tool in patients with benign and malignant ovarian tumors. Author: Gebauer G, Rieger M, Jäger W, Lang N. Journal: Anticancer Res; 1999; 19(4A):2535-6. PubMed ID: 10470190. Abstract: Measurement of CA125 is well established in the diagnosis and follow-up of ovarian cancer. CA125 determination is usually performed with the monoclonal antibodies OC125 and M11. For the IMMULITE OM-MA chemoluminsence assay (DPC Biermann, Bad Nauheim, Germany) the monoclonal antibody OV185 is used. We analysed CA125 serum concentrations of patients with benign and malignant ovarian tumors with the IMMULITE OM-MA assay by defining a cut-off at 90% specificity level. Sera of 130 patients with benign and 119 patients with malignant ovarian tumors at different FIGO stages were analysed. By calculating a cut-off of 46 U/ml, in 87 ovarian cancer patients, elevated CA125 concentrations were detected (78% sensitivity). There were no significant differences between CA125 concentrations of tumors of different histological type. The measurement of CA125 by IMMULITE OM-MA is a simple and sensitive procedure.[Abstract] [Full Text] [Related] [New Search]
