From: ER and HER2 expression are positively correlated in HER2 non-overexpressing breast cancer
Correlation of ER and HER2 transcript levels (qRT-PCR). HER2-ve is defined as HER2 FISH-ve and IHC 0/1+/2+; n = 211. HER2+ve is defined as HER2 FISH+ve and/or IHC 3+; n = 42. ER, estrogen receptor; FISH, fluorescence in situ hybridization; HER2, human epidermal growth factor receptor 2; IHC, immunohistochemistry; qRT-PCR, quantitative reverse-transcription polymerase chain reaction.
