Undetectable antimüllerian hormone levels and recovery of chemotherapy-induced ovarian failure in women with breast cancer on an oral aromatase inhibitors



Abstract
OBJECTIVE: Knowledge of the menopause status of a woman with breast cancer is important for good clinical practice. Long-lasting amenorrhea is frequent in this population, often for reasons other than definitive menopause. Antiestrogens like tamoxifen or oral aromatase inhibitors (AIs) may reactivate the ovary causing vaginal bleeding, menstruation, pregnancy, and unopposed endometrial stimulation. In contrast to tamoxifen, AIs are not active against breast cancer in the presence of functional ovaries. Antimüllerian hormone (AMH) is a potential marker of residual ovarian function that can predict not only the onset of menopause but also chemotherapy-induced amenorrhea (CIA) and fertility. We assess the value of AMH in women who recovered from CIA on an AI.
