Did You Know?

HER2-low is a new category defined by immunohistochemistry (IHC) as a score of 1+ or 2+ with a negative in situ hybridization (ISH) result (i.e., no HER2 gene amplification). Traditional HER2-targeted therapies (like trastuzumab) are only effective in HER2-positive (IHC 3+ or ISH+) cancers. However, the antibody-drug conjugate trastuzumab deruxtecan has shown efficacy in metastatic breast cancer with HER2-low expression. Accurate IHC testing is therefore critical to identify this patient population for potential treatment with this new class of drug.
