title: [24-hour CA 15/3 serum concentrations in patients with primary and metastasizing breast cancer].
abstract: Serum determinations of tumor-associated antigens in breast cancer patients are utilized for detection of metastases as well as prediction of treatment response. That is critically dependent on the validity of single daily marker determination. In our study in patients suffering from primary or metastatic breast cancer we could demonstrate fluctuations of antigens detected with the two monoclonal antibodies 115D8 and DF3 (CA-15/3) during a 24 h observation period. Beside methodical inaccuracies those fluctuating serum concentrations might be related to biological phenomena. However, on basis of our data no intra- or interindividual rhythms could be exhibited.
