[Comparison concentrations of serum CA-72.4 with CA-125 during a clinical course in patients with ovarian cancer]

The course of CA-72.4 serum concentrations was compared with the course of CA-125 in 17 patients with ovarian cancer. The serum levels of CA-72.4 were usually just above the detection range of the assay (3 units/ml). The comparison of the courses of the serum levels of both markers exhibited parallelism. However, no additional information could be obtained by determination of CA-72.4 in those patients who did not demonstrate elevated CA-125 levels at primary diagnosis or during recurrent disease.
