Human epidermal growth factor receptor 2 amplification detection by droplet digital polymerase chain reaction in formalin-fixed paraffin-embedded breast and gastric cancer samples

Abstract
DdPCR was able to identify HER2 amplification status in breast and gastric cancers with precise correlation with IHC and FISH results. This method might become a standard method for testing FFPE samples. However, the technology requires further research.
