Research on Breast Cancer Indications of Everolimus/Afinitor

Everolimus is a targeted drug that is an mTOR (mammalian target of rapamycin) inhibitor and is widely used to treat a variety of cancers, including breast cancer. In the treatment of breast cancer, everolimus is mainly used to treat hormone receptor-positive, HER2-negative advanced breast cancer, especially in patients after failure of traditional hormone therapy (such as letrozole or anastrozole). Patients with this type of breast cancer are usually postmenopausal women, and the tumors are sensitive to hormones and do not express high levels of HER2 protein. Everolimus, used in combination with other drugs such as tamoxifen and exemestane, can significantly inhibit tumor growth and improve patient survival.

In the treatment of breast cancer, the mechanism of action of everolimus is to inhibit the proliferation and survival of tumor cells by inhibiting themTOR signaling pathway. The mTOR pathway is one of the important growth and metabolic regulatory pathways in tumor cells. Everolimus reduces the proliferation of tumor cells by blocking the activity of the mTORC1 pathway and enhances the sensitivity of cancer cells to other treatments. Especially when used in combination with hormone therapy drugs, it can act synergistically and significantly improve the therapeutic effect.

Research shows that everolimus combined with hormone therapy drugs can significantly delay the progression of hormone receptor-positive, HER2-negative breast cancer. This provides a new treatment option for patients who have experienced treatment failure with letrozole or anastrozole. In addition, everolimus can also help some patients reduce the risk of tumor recurrence and extend progression-free survival.

Clinical studies in recent years have also shown that everolimus has significant efficacy in the treatment of some refractory breast cancer patients, especially in the treatment of advanced or metastatic breast cancer. The use of combination treatment strategies has also made everolimus an important drug in the treatment of breast cancer.
