[CA 15-3 and CEA as tumor markers in the diagnosis of the recurrence of breast cancer].
The significance of the tumor markers CA 15-3 and CEA for the oncological follow-up of breast cancer was examined in a retrospective analysis of 108 patients in whom, before and after hospitalization, it was possible to locate a local recurrence, a contralateral breast carcinoma, or a distant metastasis. Overall, examination of the group of patients showed that CA 15-3 was significantly more sensitive than CEA (57%/38%), with an increase of only 3% in sensitivity when investigating both markers simultaneously. Neither marker is suitable for the diagnosis of a relapse in the same region or a contralateral breast carcinoma, as pathologic values are only to be observed in one-third or, respectively, one-quarter of all cases. In cases of distant metastasis, CA 15-3 is significantly superior to CEA (osseous: 62%/41%; visceral: 73%/34%). Only where there is combined osseous/visceral metastatic spread is no significant difference manifested (87%/74%). In 15 out of 17 patients with an apparently relapse-free course both during and after hospitalization, the CA 15-3 value was normal where the CEA value was pathologic. Tumor progression would thus seem improbable where there is a pathologic CEA value in conjunction with a normal CA 15-3 value. In follow-up of breast cancer, simultaneously assay of both "nonredundant" tumor markers, which represent a useful spectrum for tumor control, is to be recommended.
