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.
To explore a method for activating the immune system against metastatic tumor cells in triple negative breast cancer (TNBC).
Key Findings:
Metastatic tumor cells activate the glucocorticoid receptor, which protects them from immune destruction.
Mifepristone inhibits this receptor, allowing immune cells to kill tumor cells in distant organs.
Combination therapy with mifepristone and anti-PD1 significantly reduced metastases and extended survival in mice.
Interpretation:
The findings suggest a promising therapeutic strategy to activate the immune system against metastatic TNBC, potentially improving patient outcomes if validated in humans.
Limitations:
The research has only been conducted in animal models, with no human trials yet.
The correlation between glucocorticoid receptor activity and metastasis in human samples needs further investigation.
Conclusion:
This study presents a novel approach to prevent metastatic disease by leveraging the immune system, which could lead to more effective treatments for TNBC and other solid tumors.
