CA 15.3 is an antigenic determinant associated with human mammary carcinomas. Two murine monoclonal antibodies have been raised against the determinants, and an immunoradiometric assay (IRMA-Kit, Centocor, USA) has been developed to determine the antigen levels in plasma of cancer patients. Based on the 99% confidence limit of healthy women, plasma values above 30 U/ml are considered abnormal. Plasma samples from 357 women were examined in the present study. Healthy females (n = 84) ranged below the cut-off level between < 10 and 29 U/ml. Higher values were found in 12.5% of benign breast diseases and in 23.6% of breast cancer patients, including all stages. Depending on the stage of the disease, there were elevated levels in 11% of operable breast cancer patients preoperatively, in 7% of the cases with no evidence of disease after primary treatment and in 63.5% ofpatients with disseminated mammary carcinoma. In metastasized breast cancer the frequency and the degree of abnormal titers were closely related to the extent of the metastatic disease. Follow-up examinations of 63 patients under cytotoxic therapy showed CA 15.3 changes correlating well with the clinical course in up to 90% of the antigen positive cases. The present data indicate that CA 15.3 may be useful in the surveillance of breast cancer patients. However in our study one third of the patients with metastatic breast cancer did not show any increase in CA 15.3 and must be regarded as antigen negative.

Serum levels of CEA, CA 15.3 and CA 27.29 were measured during the follow-up of 499 breast cancer patients. Studies included three different groups of women: 82 blood donors free of disease, 42 patients with non-malignant breast diseases and 499 breast cancer patients. After the determinaion of cut-off values, serum levels of tumor markers did not show significant elevations in benign breast diseases. On the basis of our results CA 15.3 (sensitivity = 57%; accuracy = 87%) was the most effective marker, CA 27.29 (sensitivity = 62%; accuracy = 83%) was the most sensitive and CEA (sensitivity = 45%; accuracy = 81%) was the least sensitive and effective marker. The combined use of markers was evaluated by step-wise logistic regression analysis. The regression coefficients showed that CA 15.3 (coeff. = 2.97) and CA 27.29 (coeff. = 1.46) were suitable for the detection of possible metastases during follow-up. Finally, we studied the relationship between pT, pN, pM and circulating levels of CA 15.3 and CA 27.29.

Breast Cancer Patients

TPS, CA 15-3 and CEA were determined in metastatic breast cancer patients during treatment. After six months of follow-up the patients were divided into four groups according to the UICC criteria for treatment response. Forty-six patients with a more favorable prognosis (complete remission, partial remission or stable disease) were followed for an extended period. In 30 of the 46 patients at least one marker had increased at the end of the six-month period by at least 25% (TPS in 54%, CA 15-3 in 20%, CEA in 20%). All these 30 patients subsequently developed progression. The prognostic sensitivity was 83%, 30% and 30%, respectively, for TPS, CA 15-3 and CEA. The combination of TPS and CA 15-3 showed a sensitivity of 96%. The median lead time was about 8 months for TPS and CA 15-3, but less than 50% of the patients showed a lead time for CA 15-3 as compared to TPS. We conclude that TPS and CA 15-3 determinations are helpful for the prediction of progression during the follow-up of breast cancer patients.

Cutoff Levels

In order to verify the efficiency of the tumor markers CA 15.3 and CA 549 in the follow-up of breast cancer patients, it was necessary first to check the cutoff levels of each tumor marker in women with an increased age-related risk, but with no evidence of disease. From 132 serum samples in this age group, we confirmed the CA 549 cutoff level of 12.1 U/ml. However, the cutoff of CA 15.3 was 34 U/ml, which is higher than previously reported in the literature. Fifty-two breast cancer patients with or without metastases at the time of entry into the study were followed for 2 to 3 years with both tumor markers. The sensitivity, specificity and the test efficiency for the presence of metastases were analyzed with each tumor marker. Taking into account the different cutoff levels, we concluded that both tumor markers can be used independently to follow the clinical situation of patients. In several cases an increase in both tumor markers was observed before a clinical diagnosis of metastases could be made. Combination of these two tumor markers gave no more significant information about the patient's clinical situation than each tumor marker alone.
