[Tumor markers MCA and CA-125 in the diagnosis and monitoring of breast cancer].

The value of MCA and CA-25 tumor marker assays for diagnosis and treatment of breast cancer was analysed on the basis of measurements made in 320 healthy females and 85 breast cancer patients. A procedure for DK assay with anticipated specificity, sensitivity and reliability is described. MCA measurement was shown to be important for breast cancer diagnosis. The reliability of the latter test for diagnosing progression in the course of follow-up was 91%. Progression of the disease was shown to be associated with an increase in blood CA-125 level in 60% of cases.
