Post-treatment anti-Mullerian hormone (AMH) levels predict long-term ovarian dysfunction in women with hematological malignancies

Fertility is a concern in young female survivors of hematological malignancies. We evaluated post-treatment ovarian function in patients by measuring anti-Mullerian hormone (AMH) and conventional hormone levels to correlate with menstruation and fertility. The prospective cohort study included 29 reproductive-aged women diagnosed with Hodgkin lymphoma (n = 11), non-Hodgkin lymphoma (n = 9) or acute myeloid leukemia (n = 9). Hormone assays were measured after treatment was completed and compared to age-matched healthy controls. Menstrual changes and postmenopausal symptoms were assessed annually. Serum AMH levels were significantly lower compared to controls at 12 months after treatment [1.0 (0.18-1.8) vs. 2.2 (1.8-4.8) ng/mL; P < .001). At 12 months, FSH and LH levels were significantly higher compared to controls. The interruption of menstrual cycles was observed in 80% (22/27) of patients. Normal menstruation returned at a median of 1.5 months after cessation of treatment in 71% of patients, while 29% of patients had persistent amenorrhea. Low AMH levels at 12 months after therapy (<1 ng/mL) correlated more strongly with abnormal menstrual cycles than normal AMH levels (46% vs. 0%, P = .04). Four patients with low AMH consulted an infertility clinic. In summary, low serum AMH at 12 months after chemotherapy was associated with persistent menstrual abnormalities.
