Estrogen receptors (ER) are found in approximately 50% of breast tumor specimens obtained from metastases. The presence of significant ER concentrations in a tumor specimen is associated with a response rate of about 60% to endocrine therapy, while its absence greatly decreases the likelihood of response to endocrine therapy. The present study provides a preliminary analysis of response rate to tamoxifen therapy as a function of ER status.
