Abstract:
Searching for biomarkers that associated with the acquired resistance of malignant cells to epidermal growth factor receptor (EGFR)-targeting monoclonal antibodies is crucial to improve the clinical benefits of these therapeutic agents. We have recently demonstrated that molecular alterations in both oncogenic and immunological pathways may be responsible for such an insensitivity. Our findings suggest that a combination of targeted anticancer agents and immunomodulatory drugs may be useful for overcoming the acquired resistance of cancer cells to EGFR-specific monoclonal antibodies.
Insights
Identifying biomarkers for acquired resistance to epidermal growth factor receptor (EGFR) antibodies is key. Molecular changes in cancer pathways suggest combining targeted therapy with immunomodulatory drugs can overcome resistance.
