What are Some Examples of Biomarker Assays in Cancer?
There are numerous biomarker assays used in clinical practice. For instance, the HER2/neu assay is used in breast cancer to determine HER2 protein overexpression, guiding the use of targeted therapies like trastuzumab. The KRAS mutation assay helps decide on the appropriateness of EGFR inhibitors in colorectal cancer treatment. Similarly, the PD-L1 expression assay is used in various cancers to assess eligibility for immunotherapies.
