Dana-Farber Research Uncovers Approach to Activating the Immune System Against Metastatic Breast Cancer

Cancer spreads, or metastasizes, when tumor cells shed from a primary solid tumor, for example in the breast, and embed in other organs, such as the lung, liver, and brain, and begin to grow.

    Dana-Farber researchers discovered a method to activate the immune system against metastatic breast cancer.

  • 2

    The study focused on triple negative breast cancer and identified a glucocorticoid receptor that aids tumor cell survival.

  • 3

    Mifepristone, an FDA-approved drug, was found to inhibit the glucocorticoid receptor, enhancing immune cell effectiveness.

  • 4

    Combining mifepristone with an anti-PD1 immune checkpoint inhibitor further reduced metastases in animal models.

  • 5

    This research suggests a potential new strategy for preventing metastatic disease in breast cancer and other solid tumors.
