HER2-low has some HER2 proteins on the cell surface, but not enough to be classified as HER2-positive. [4] Trastuzumab deruxtecan is the first approved therapy by the US Food and Drug Administration (FDA) targeted to people with the HER2-low breast cancer subtype. [4] DNA-based classification.
HER2 is a member of the human epidermal growth factor receptor (HER/EGFR/ERBB) family. But contrary to other members of the ERBB family, HER2 does not directly bind ligand. HER2 activation results from heterodimerization with another ERBB member or by homodimerization when HER2 concentration are high, for instance in cancer. [8]
AstraZeneca's (AZN) Enhertu reduces the risk of disease progression by 72% in HER2-positive metastatic breast cancer. Imfinzi plus chemotherapy triples patient survival at three years in ES-SCLC.

At the age of 35 to 40 years, or once childbearing is completed, the procedure is recommended for risk reduction purposes.
Pertuzumab is administered as an intravenous infusion in combination with trastuzumab and docetaxel as a first line treatment for HER2-positive metastatic breast cancer. [4] [3] It is also used in the same combination as a neoadjuvant (given to reduce the size of a tumor, prior to surgery or radiation) for HER2-positive early breast cancer; as of 2016 this use had not been shown to increase ...
The HER2 gene (also known as HER2/neu and ErbB2 gene) is amplified in 20–30% of early-stage breast cancers. [44] Trastuzumab is a monoclonal antibody targeting HER2, inducing an immune-mediated response that causes internalization and recycling of HER2. It may also upregulate cell cycle inhibitors such as p21 Waf1 and p27 Kip1. [58]
