Study of the Effect of Letrozole on Breast Biomarkers of High Risk Postmenopausal Women Receiving Hormone Replacement Therapy
A pilot study of letrozole in postmenopausal women on hormone replacement therapy at high
risk of developing breast cancer. Subjects will have hyperplasia with atypia (or borderline
EH/AH) and evidence of ER expression by random periareolar fine needle aspiration and
baseline serum estradiol levels less than or equal to 150 pg/ml. The feasibility of
performing RT-PCR on breast specimens for aromatase expression will also be done at
baseline.
