The cell surface integrin αvβ3 overexpresses in most cancers and newly g...

Background Up to 23% of breast cancer patients recurred within a decade after trastuzumab treatment. Conversely, one trial found that patients with low HER2 expression and metastatic breast cancer had a positive response to trastuzumab-deruxtecan (T-Dxd). This indicates that relying solely on HER2 as a single diagnostic marker to predict the effica...

Epidermal growth factor (EGF) binds with its surface receptor to stimulate gene expression and cancer cell proliferation.
