Abstract
Significance: This biomarker study explored HER2 expression levels and immune cell characteristics that may affect response to T-DXd using tumor tissue samples collected from clinical trial participants. The results suggest that HER2 expression levels and tumor characteristics before the initiation of T-DXd may correlate with the efficacy of the drug.
