Comparison of GIDE score and change in Ki67 immunohistochemistry with ESR1 and ERBB2 expression. (a) Significant positive correlation of the Global Index of Dependence on Estrogen (GIDE) scores for each pair of biopsies with percentage decrease in Ki67 immunohistochemistry (IHC) is shown. (b) Significant negative correlation of the GIDE score to the pretreatment expression of ERBB2, as derived from microarray profiling, is shown. Also shown are comparisons of the change in Ki67 immunohistochemistry (% decrease) is shown with pretreatment (c) ESR1 expression and (d) ERBB2 expression. Finally, comparisons of GIDE scores with pretreatment immunohistochemical measurements (Allred scores) are shown for (e) estrogen receptor (ER) and (f) progesterone receptor (PgR).
