Popis: SUMMARY The majority of patients with breast cancer are estrogen- and progesterone-receptor positive, and have benefited from the development of anti-estrogen therapies, such as tamoxifen and aromatase inhibitors. Unfortunately, metastatic patients will eventually develop resistance to these agents. Inhibitors of the mTOR, particularly everolimus, show promising activity in this group of patients. mTOR inhibition appears to reverse resistance to anti-estrogen therapy in the estrogen-receptor-/progesterone-receptor-positive subset. Additionally, they may have a similar effect by reversing anti-HER2 resistance in patients who overexpress HER2. This article reviews the mechanism of action of mTOR inhibitors and summarizes the available clinical data of their use in breast cancer.
