[CA 15-3 associated with CEA and TPA in the follow-up of breast carcinoma].
1990
: The serum level measurement of CA 15-3 antigen was evaluated in association with CEA and TPA, during the follow-up in mastectomized patients previously affected by breast cancer: 94 patients with metastases and 319 without apparent disease evolution. In the group of patients with metastases, the CA 15-3 antigen showed high sensitivity (70.2%). The CA 15-3 and TPA association increased the sensitivity (87.2%), while the CEA and CA 15-3 association did not increase this parameter. All markers showed good correlation with therapeutic response. Thirteen patients among 19 without apparent disease evolution, developed metastases, during the follow-up. The CA 15-3 and/or TPA increase allowed to predict disease progression in 13/13 cases, 2-10 months before clinical evidence. Our experience shows that CA 15-3 measurement associated with TPA, during the follow-up of patients affected by breast cancer, may be helpful for increasing the predictivity with respect to those patients most likely to develop recurrent disease.
