HER2 Key Differences and Current Approaches to Biomarker Testing

Author(s)Misako Nagasaka, MD, PhD

Panelist discusses how HER2 testing evaluates protein overexpression, gene amplification, and mutations. Although breast and gastric cancers typically show overexpression/amplification, other tumors more commonly harbor mutations.
