Bilateral Salpingo-oophorectomy Compared to Gonadotropin-Releasing Hormone Agonists in Premenopausal Hormone Receptor-Positive Metastatic Breast Cancer Patients Treated with Aromatase Inhibitors.

ABSTRACT:

Purpose

Although combining aromatase inhibitors (AI) with gonadotropin-releasing hormone agonists (GnRHa) is becoming more common, it is still not clear if GnRHa is as effective as bilateral salpingo-oophorectomy (BSO).

Materials and methods

We retrospectively analyzed data of 66 premenopausal patients with hormone receptor- positive, human epidermal growth factor receptor 2-negative recurrent and metastatic breast cancer who had been treated with AIs in combination with GnRHa or BSO between 2002 and 2015.

Results

The median patient age was 44 years. Overall, 24 (36%) received BSO and 42 (64%) received GnRHa. The clinical benefit rate was higher in the BSO group than in the GnRHa group (88% vs. 69%, p=0.092). Median progression-free survival (PFS) was longer in the BS
