Key clinical point: Administration of g onadotropin-releasing hormone analogs (GnRHa) with chemotherapy reduced the risk for premature ovarian insufficiency (POI) in premenopausal women with breast cancer.
Major finding: At 12 months after chemotherapy, POI was reported by 10.3% vs 44.5% of patients in the GnRHa + chemotherapy vs chemotherapy-only group (odds ratio, 0.23; P < .001). No serious adverse events were reported.
Study details: Findings are from a phase 3 superiority trial including 330 premenopausal women with stages I-III operable breast cancer who were randomly assigned to GnRHa (3.6 mg of goserelin or 3.75 mg of leuprorelin) + chemotherapy or chemotherapy alone.
Disclosures: This study was funded by the Science and Technology Commission, Shanghai, and Zhejiang Medical Association. Dr. Zong reported receiving grants from the Science and Technology Commission of Shanghai Municipality.
