title: Complete estrogen blockade with buserelin and aminoglutethimide for advanced breast cancer: a phase I-II study with long-term hormonal correlations.
abstract: We treated 21 patients with advanced breast cancer with buserelin, aminoglutethimide and cortisone acetate in an attempt to obtain a complete estrogen blockade both in premenopausal and postmenopausal patients. Ten patients (47%) obtained an objective response without any relevant side-effects. Dealing with hormonal data, it must be outlined that serum testosterone levels decreased significantly in postmenopausal patients, suggesting a possible explanation for the activity of luteinizing hormone-releasing hormone analogue in this group of patients.
