ABSTRACT
OBJECTIVES: Allogeneic hematopoietic stem-cell transplantation (HCT) is the only curative option for most hematologic malignancies. However, HSCT can cause early menopause and various complications in premenopausal women. Therefore, we aimed to investigate risk factors predicting early menopause and its clinical implications among survivors post HCT. METHODS: We retrospectively analyzed 30 adult women who had received HCT at premenopausal status between 2015 and 2018. We excluded patients who had received autologous stem cell transplantation, had relapsed, or died of any cause within 2 years of HCT. RESULTS: The median age at HCT was 41.6 years (range, 22-53). Post-HCT menopause was identified in 90% of myeloablative conditioning (MAC) HCT and 55% of reduced-intensity conditioning (RIC) HCT (p = .101). In the multivariate analysis, the post-HCT menopausal risk was 21 times higher in a MAC regimen containing 4 days of busulfan (p = .016) and 9.3 times higher in RIC regimens containing 2-3 days of busulfan (p = .033) than that of non-busulfan-based conditioning regimens. CONCLUSIONS: Higher busulfan dose in conditioning regimens is the most significant risk factor affecting post-HCT early menopause. Considering our data, we need to decide on conditioning regimens and individualized fertility counseling before HCT for premenopausal women.
