Trastuzumab Deruxtecan, With or Without Endocrine Therapy, Shows Promising Responses in Operable HR+, HER2-Low Breast Cancer

"...Additionally, the study demonstrated that trastuzumab deruxtecan yielded dynamic changes in HER2 tissue expression; 48.6% of patients (n = 17) experienced a change in HER2 IHC expression after trastuzumab deruxtecan treatment. Among patients who experienced a change, 88.2% had a decrease in HER2 expression between baseline and surgery—this included a subset of patients with HER2 IHC-0 disease...."
