Résumé
Eleven breast cancer patients [stage II] aged 43-52 years were pre- and postoperatively followed up with serial determinations of serum carcinoembryonic antigen [CEA], cancer antigen 15.3 [CA15- 3], mammary carcinoma antigen [MCA], progesterone and estradiol to assess the clinical value of these parameters in the diagnosis of breast cancer. The mean preoperative values of the abovementioned parameters in patients with breast cancer were statistically significantly higher than controls. In addition, the concentrations of CEA, CA15- 3, progesterone and estradiol in the serum postoperatively showed a significant change compared with their levels before surgery. The results indicated the existence of a good correlation between serum CEA with CA15-3 and CAl5-3 with progesterone pre- and postoperatively in breast cancer patients
