DNA Damage Repair Pathways and Targeted Therapy for Doxorubicin-Resistant Breast Cancer.

Mapping how breast cancers resist chemotherapy reveals specific drug targets that may restore treatment effectiveness in previously resistant tumors.

This review maps how DNA damage repair pathway upregulation drives doxorubicin resistance in breast cancer and catalogues emerging targeted agents that exploit these vulnerabilities. While not providing new primary data, it provides a useful clinical summary of DDR-targeting strategies relevant to the growing problem of anthracycline-resistant breast cancer.
