title: CA 125 in the follow-up of patients with ovarian cancer.
abstract: Three hundred and ninety-five CA 125 serum values of 72 patients with ovarian cancer were correlated with the clinical status. With a threshold value of 35 U/ml we found true negative values in 85% and true positive values in 93%. No correlation between preoperative CA 125 values and tumor stage was noted at primary surgery. During follow-up, 17 women had marker values between 35 and 65 U/ml. Three out of 7 women in clinical remission showed a value greater than 65 U/ml at subsequent follow-up and developed recurrent disease. In 8 patients out of 20 re-laparotomies, tumors with a maximum diameter of greater than 2 cm were confirmed with a preoperative serum CA 125 concentration greater than 65 U/ml. Two out of 3 patients with a tumor diameter less than 2 cm at re-laparotomy revealed CA 125 serum concentrations less than 35 U/ml. A false positive CA 125 value was found in one patient without demonstrable active disease. The calculated doubling time of the CA 125 values ranged between 23 and 173 days; the median value was 67 +/- 47 days. After 6.2 +/- 1.3 doubling times death ensued.
