Abstract
Estrogen receptor-positive breast cancer is a heterogeneous disease characterized by its dependence on estrogen for growth and progression. Although hormonal therapy remains the cornerstone of treatment, many patients eventually develop resistance, leading to recurrence and disease progression. This case report describes a durable response to a rechallenge with Anastrozole (Arimidex) in combination with Everolimus (Afinitor), an mTOR inhibitor, in a patient with advanced (stage IV) ER+ metastatic breast cancer.
