Abstract
PURPOSE: This study evaluated predictive factors for recovery of ovarian function after ovarian protection by GnRH agonist during chemotherapy in young breast cancer patients. METHODS: This prospective cohort study analyzed 105 young breast cancer patients who were studied longitudinally after receiving GnRH agonist during cyclophosphamide-based chemotherapy for ovarian protection. Associations between pretreatment hormones, clinical factors, and recovery of ovarian function (resumption of menstruation or anti-Müllerian hormone (AMH) ≥ 1 ng/ml) were evaluated at 12 months and long-term follow-up after completion of chemotherapy. RESULTS: Mean age was 32 years (range 23-42 years). In multivariate analyses, tamoxifen use (P = 0.035) and pretreatment follicle-stimulating hormone (FSH) (P = 0.032) were predictive of resumption of menstruation, and age (P = 0.019), tamoxifen use (P = 0.022), pretreatment FSH (P < 0.001), and AMH (P = 0.040) were predictors for AMH ≥ 1 ng/ml at 12 months. In addition, pretreatment AMH was a predictor for AMH ≥ 1 ng/ml after long-term follow-up. Receiver operating characteristic curve analyses gave area under the curve of 0.805 for resumption of menstruation and 0.903 for serum AMH concentration ≥ 1 ng/ml at 12 months, when age, tamoxifen use, pretreatment FSH, and AMH were combined. CONCLUSION: Pretreatment AMH (3.26 ng/ml), age (33.9 years), pretreatment FSH (5.5 IU/l), and tamoxifen use are useful predictors for AMH ≥ 1 ng/ml at 12 months after GnRH agonist. This finding will support patient and clinician decision-making regarding fertility preservation.
