Changes in the tumor marker concentration in female patients with hyper-, eu-, and hypothyroidism.

The levels of 6 circulating tumor markers were evaluated in a total of 131 female subjects with altered thyroid states; 36 normal subjects, 46 hyperthyroid patients with Graves' disease, and 49 primary hypothyroid patients. The mean CEA concentration was observed to be significantly higher (p less than 0.02) in hypothyroid patients than in normal and hyperthyroid patients (1.1 +/- 0.1 ng/ml, 0.8 +/- 0.1 ng/ml and 0.8 +/- 0.1 ng/ml, respectively). Similarly, the mean serum CA 125 concentration in hypothyroid patients was higher (p less than 0.02) than in normal and hyperthyroid patients (13.0 +/- 2.6 U/ml, 7.6 +/- 1.1 U/ml and 5.5 +/- 0.8 U/ml, respectively), and the mean serum CA 15-3 concentration in hypothyroid patients was significantly higher than in normal subjects (p less than 0.01) and hyperthyroid patients (p less than 0.001) (16.2 +/- 0.9 U/ml, 13.9 +/- 0.6 U/ml and 10.6 +/- 0.5 U/ml, respectively). No statistical difference was found in mean CA 19-9 in the three subject groups. AFP in the hypothyroid patients (3.6 +/- 0.3 ng/ml) was significantly higher (p less than 0.05) than in normal subjects (2.6 +/- 0.2 ng/ml) and hyperthyroid patients (1.7 +/- 0.2 ng/ml) (p less than 0.01). On the other hand, serum ferritin was low in the hypothyroid patients (65.9 8.0 ng/ml) and significantly increased (69.1 +/- 9.0 ng/ml) (p less than 0.02) with the normalization of thyroid function. In hyperthyroidism, serum ferritin (70.2 +/- 7.0 ng/ml) was significantly higher than in the hypothyroid patients (p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
