Abstract

Background: Chemotherapy impairs ovarian function in premenopausal breast cancer patients. Many breast cancer patients experience menopause earlier and therefore lose their reproductive abilities. The protective effect of gonadotropin-releasing hormone agonist (GnRha) upon the ovary is clearly apparent for hormone receptor (HR) negative patients, although the available data is not consistent for the patient body as a whole when considered regardless of HR status. It is also unknown whether levels of Anti-Mullerian Hormone (AMH) can reflect the influence of chemotherapy upon the ovary.

Methods: We randomly assigned 98 premenopausal breast cancer patients regardless HR-positive or -negative to receive either standard chemotherapy with GnRHa (GnRHa group) or standard chemotherapy without GnRHa (control group). Our primary end point was ovarian failure rate (OVF) at 1 year. In addition, we observed the change of AMH level during chemotherapy and the association between AMH and OVF.

Results: OVF was significantly lower (44.7%) in the GnRHa group than in the control group (80.6%; P=0.002). Median AMH levels were significantly higher before chemotherapy when compared to after 1/2cycles of chemotherapy, both in the GnRHa group (1.86ng/ml vs 0.12ng/ml; P=0.000) and in the control group (1.57ng/ml vs 0.10ng/ml; P=0.000). OVF was 91.3% in the AMH baseline level <1.1ng/ml group and 63.5% in the AMH baseline level >1.1ng/ml group (P=0.013).

Conclusion: Data showed that GnRHa may have a protective effect on young breast cancer patients regardless of HR during chemotherapy. AMH could reflect changes of OVF during chemotherapy and predict OVF after chemotherapy.
