Plasma multi-omics reveals molecular remodeling and prognostic biomarkers in advanced breast cancer treated with trastuzumab deruxtecan
Trastuzumab deruxtecan (T-DXd), a HER2-targeted antibody-drug conjugate, has demonstrated clinical activity in HER2-positive and HER2-low advanced breast cancer. However, treatment outcomes remain heterogeneous, and circulating molecular correlates of treatment and prognosis are incompletely defined. Twenty-...
