Biomarkers Used for Treatment Selection

The following biomarkers may be used to select treatment for cancer. This is not a complete list of all biomarkers and available treatments. Additional biomarkers may be used to for clinical research studies. Speak with your doctor about additional testing which may help guide your treatment.
