Serum CA 125 levels and survival in advanced ovarian cancer

We made a retrospective analysis of 85 patients with elevated serum CA 125 after surgery for ovarian cancer. Absolute CA 125 serum levels were a poor guide to prognosis. However, the ratio between the serum CA 125 after the first, second, or third course of treatment and the postoperative value was an excellent guide to prognosis. These were also independent and stable in the Cox Regression analysis.
