We screened for the prognostic value of estrogen receptor (ER) and progesterone receptor (PR) through a multicentric study of 2,257 operable breast cancer patients who did not received adjuvant therapy. Three hundred and seven local-regional recurrences, 105 metachronous contralateral breast cancer, 589 metastases and 537 deaths from cancer had been diagnosed with a median follow-up of 8.5 years. A total of 69% of the tumors were ER positive and 54% PR positive. For statistical analysis, 1,665 patients were studied because of complete clinical and biological data. In univariate analysis, ER and PR status were of prognostic value for the metastases-free interval (MFI) and the overall survival (OS). In multivariate analysis (Cox proportional hazard model), only the ER status showed a significant difference between positive and negative groups regarding the MFI and OS. By using Cox regression model with time-dependent covariates, we show that the predictive value of ER status of the primary tumor decreases by approximately 20% per year, losing its significance after 8 years of follow-up. These results show that ER and PR status have a relatively limited predictive value and their major interest remain in the domain of therapeutic decision.

D011960 Receptors, Estrogen Cytoplasmic proteins that bind estrogens and migrate to the nucleus where they regulate DNA transcription. Evaluation of the state of estrogen receptors in breast cancer patients has become clinically important. Estrogen Receptor,Estrogen Receptors,Estrogen Nuclear Receptor,Estrogen Receptor Type I,Estrogen Receptor Type II,Estrogen Receptors Type I,Estrogen Receptors Type II,Receptor, Estrogen Nuclear,Receptors, Estrogen, Type I,Receptors, Estrogen, Type II,Nuclear Receptor, Estrogen,Receptor, Estrogen
D011980 Receptors, Progesterone Specific proteins found in or on cells of progesterone target tissues that specifically combine with progesterone. The cytosol progesterone-receptor complex then associates with the nucleic acids to initiate protein synthesis. There are two kinds of progesterone receptors, A and B. Both are induced by estrogen and have short half-lives.
