Use of LH-RH agonists in the treatment of breast disease
Published online by Cambridge University Press: 05 December 2011
Synopsis
The effects of LH-RH agonists in advanced breast cancer patients are reviewed and compared to the efficacy of surgical ablation of the ovaries and X-ray induced menopause in the treatment of this disease. In both pre- and postmenopausal women, LH-RH agonists produce pituitary gland desensitisation and a fall in concentrations of LH and FSH. In premenopausal patients plasma progesterone and oestradiol levels fall to the castrate or postmenopausal range within three to four weeks. Tumour remissions have been observed in approximately 30% of premenopausal women (50% ER-positive) and approximately 10% of postmenopausal patients. The mechanism of action of LH-RH agonists is discussed and their current application to combined endocrine therapy, early breast cancer and mastalgia briefly outlined.
