Abstract
- Both estrogen and progesterone receptors have been determined in 613 primary breast cancer patients treated by radical mastectomy. At the cut-off value of 5 fentomoles (fmol) cytosol protein/mg for both receptors, patients with estrogen or progesterone receptor-positive breast cancer showed significantly favorable disease-free, overall and post-recurrence survival curves to those of receptor-negative breast cancer patients. In the patient subgroups: premenopausal, stage III, more than four positive lymph node metastases, postoperative adjuvant tamoxifen therapy, a significantly favorable prognosis was recognized in either estrogen or progesterone receptor-positive patients. Both receptors are thought to be useful prognostic indicators for patients with advanced tumors or for those receiving postoperative adjuvant tamoxifen therapy. When the cut-off value was changed, the maximum significant difference in prognosis between receptor-positive and receptor-negative patients was observed at 5 fmol cytosol protein/mg for the estrogen receptor or 10 fmol/mg cytosol protein for the progesterone receptor. A more detailed examination should be made on the cut-off values of both receptors.
