Tumor markers were prospectively (CEA and CA 15.3) or retrospectively (c-erbB-2) studied in the sera of 503 untreated patients with breast cancer diagnosed from 1988 to 2001. Abnormal c-erbB-2 levels (> 15 U/ml) were found in 7%, CEA in 12% and CA 15.3 in 13% of the 503 patients. C-erbB-2 serum levels were only related to c-erbB-2 in tissue, with significantly higher concentrations in patients with positivity in tissue. All the tumor markers (c-erbB-2 only in patients with positivity in tissue) were correlated with tumor size, TNM and nodal involvement. CEA was also related to menopausal status, c-erbB-2 overexpression in tissue and ER. Univariate analysis (mean follow-up 8 years) showed that CEA and CA 15.3 were prognostic factors with significantly shorter disease-free survival (DFS) and overall survival (OS) in patients with pretreatment tumor marker positivity. Multivariate analysis in DFS and in OS showed that nodal involvement CEA and ER but not tumor size, menopausal status, histological grade, histology, CA 15.3, c-erbB-2, PgR, adjuvant treatment, p53 (345 patients) or c-erbB-2 in tissue are independent prognostic factors. In summary, tumor markers are a useful, inexpensive and reproducible tool for prognosis in breast cancer.
