Abstract
The aim of this study was to find out if it is possible to predict the clinical response to bilateral oophorectomy in premenopausal patients with advanced breast cancer. Two methods of determination were used before oophorectomy: 1) the presence of estrogen receptors in the tumor tissue; 2) the urinary concentration of androgens. The clinical response to oophorectomy was evaluated after a six-month follow-up. Determinations carried out on 49 patients showed that a significant correlation exists between clinical response to oophorectomy and androgenic activity alone or in combination with estrogen receptors when both tests give concordant results.
