Expression of HER2 and hormone receptors in breast cancer subtypes by total HER2 load or hormone receptors. Expression of estrogen receptor (A) and progesterone receptor (B) in three subtypes identified by total HER2 load previously. Expression of TH2 in new subtype classification by quantitative analysis of hormone receptors based on quantum dot nanotechnology (C) and by conventional classification using traditional methods (D).

Abbreviations: CISH, chromogenic in situ hybridization; HTH2&CISH+, high total HER2 load (HTH2) and CISH-positive; HTH2&CISH−, HTH2 and CISH negative; LTH2, low TH2; HHR, high hormone receptor expression; LHR, low hormone receptor expression; NHR, negative hormone receptor expression; TH2, total HER2 load; HER2, human epidermal growth factor receptor 2; ER, estrogen receptor; PR, progesterone receptor.
