Abstract

Hormone-dependent (ER/PR-positive), human epidermal growth factor 2 receptor-negative (HR+/HER2 negative) breast cancer (BC) accounts for more than 70% of all BC cases. Significant progress in the treatment of HR+/HER2-negative metastatic breast cancer (mBC) has been made, in particular, more adapted and targeted treatments have been developed. Recently, a better understanding of the role of the PI3K/AKT/mTOR signaling pathway in BC has led to the development of PI3K inhibitors that have proven effective in the treatment of HR+/HER2-negative mBC. The role of the PI3K/AKT/mTOR pathogenetic pathway in BC and treatment methods aimed at PI3K inhibition were studied. The development of the PI3K inhibitor alpelisib, indications for its use in HR+/HER2-negative mBC has been completed, safety and tolerability as well as the future direction of this therapy in the treatment of breast cancer are being discussed.
