AMH Predicts Postchemotherapy Menopause in Premenopausal Breast Cancer Patients

Not yet recruiting
Conditions
Breast Cancer
Registration Number
NCT06313476
Lead Sponsor
Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University
Brief Summary

To determine the accuracy of AMH postchemotherapy in predicting permanent menopause after chemotherapy in breast cancer patients who did not use OFS before menopause

Detailed Description

For early breast cancer women who are premenopausal, after receiving chemotherapy (neoadjuvant chemotherapy or adjuvant chemotherapy), not using OFS as ovarian suppression, AMH, E2 and FSH levels will be measured by blood sampling before chemotherapy, at the end of chemotherapy and 1 month, 3 months, 6 months, 12 months, 18 months and 24 months after chemotherapy. The menstrual status of patients will be also followed up. At several timing, investigators will analyze AMH level, E2 level, FSH level, proportion of unmeasured AMH (AMH≤0.02ng/ml), proportion of E2 that conforms to menopausal status (E2≤30ng/L), proportion of FSH that conforms to menopausal status (FSH \> 30U/L), proportion of persistent amenia (no menstruation from the end of chemotherapy to the evaluation time) and incidence of adverse reactions
