Fig. 1: ER and PR expression in primary and metastatic breast cancer.
From: Receptor conversion in metastatic breast cancer: analysis of 390 cases from a single institution
Dot plot (top panel) and line graph (bottom panel) of ER and PR expression in paired primary and metastatic breast cancer. There was a significantly decreased expression of both ER and PR in the metastases (mean H-score and 95% confidence interval: 172 ± 16 vs. 129 ± 17, P < 0.0001 and 77 ± 13 vs. 33 ± 9, P < 0.0001, respectively).
