Comparison of outcomes in patients with luminal type breast cancer treated with a gonadotropin-releasing hormone analog or bilateral salpingo-oophorectomy: A cohort retrospective study.

Introduction: Premenopausal patients with hormone receptor-positive breast cancer require ablation therapy via a pharmacological or surgical approach. Data comparing outcomes between treatment with gonadotropin-releasing hormone (GnRH) analogs and treatment with bilateral salpingo-oophorectomy (BSO) in Indonesia remains limited. Therefore, this study aimed to compare incidence of local recurrence and metastasis, and overall survival (OS) in patients with luminal type breast cancer treated using the two approaches.
