Anti-müllerian hormone levels and evolution in women of reproductive age with breast cancer treated with chemotherapy

International audienceBackground: Long-term consequences of cancer treatments in young women, and especially fertility issues, are gaining attention as survival rates increase. Breast cancer is the most frequent malignancy in women of reproductive age.Aim: The purpose of this review is to describe serum anti-mü llerian hormone (AMH) level at diagnosis and its evolution during and after chemotherapy in women of reproductive age treated for breast cancer. Second, the impact of taxanes on AMH, the association between AMH and amenorrhea, and the comparison of AMH with other hormonal markers of ovarian reserve were studied.Methods: A systematic PubMed search was conducted on all articles, published up to April 2016 and related to AMH in women suffering from breast cancer using the following key words: AMH, mü llerian-inhibiting substance, ovarian reserve, ovarian function, breast cancer, gonadotoxicity, ovarian toxicity, amenorrhea, chemotherapy, and menopause.Results: AMH levels rapidly fall down to undetectable levels in most women during chemo-therapy and generally persist at very low levels in most women after the treatment. Taxanes seem to impact negatively ovarian function, but data on ovarian reserve are scarce. AMH is a predictor of the occurrence of chemotherapy-related amenorrhea and is the most relevant hormonal marker of ovarian reserve.Conclusion: Serum AMH is a relevant tool for ovarian reserve assessment and follow-up during treatment in premenopausal women with breast cancer. Further large prospective studies are necessary to determine its predictive interest for post-treatment residual fertility, and eventually use it in fertility preservation counseling before treatment initiation
