Abstract:
To determine the impact of dose-dense chemotherapy administration on ovarian reserve in women undergoing treatment for breast cancer. We conducted a retrospective cohort study of reproductive age women who underwent dose-dense chemotherapy regimens with doxorubicin hydrochloride and cyclophosphamide with or without paclitaxel for a new diagnosis of breast cancer. We compared pre- and post-treatment serum antimullerian hormone (AMH) levels and assessed changes in AMH over time. Fifty-seven patients met inclusion criteria. Median pre-treatment AMH was 2.9 ng/mL, whereas post-treatment AMH was 0.1 ng/mL, demonstrating a dramatic reduction in AMH levels after treatment with a dose-dense regimen. This change was independent of age and was sustained over 12 months from treatment completion. Dose-dense chemotherapy regimens for breast cancer lead to marked and sustained decreases in AMH irrespective of patient age.
