Future uses for aromatase inhibitors in breast cancer

J Steroid Biochem Mol Biol. 1997 Apr;61(3-6):261-6.


Over recent years highly potent, well-tolerated aromatase inhibitors have been developed, which essentially obliterate peripheral aromatase activity in postmenopausal women. Their role as the optimal second-line agents (post-tamoxifen) for the treatment of advanced breast cancer has recently been established in large comparative clinical trials. Their testing as adjuvant therapy is warranted, but their eventual application in this (or the prophylactic) setting will be dependent on the currently unknown effects of profound oestrogen deprivation on the physiology of postmenopausal women as well as on its efficacy. It is also possible that these new compounds could suppress oestrogen synthesis in premenopausal women, but the consequences on ovarian folliculogenesis might prevent their widespread use in this group of patients.
