Figure 4. Maintenance of GATA3 and ER expression in lymph node metastases of luminal breast cancers.
Samples from node-negative (PNM) or node-positive (PM) primary tumors, regional lymph node metastases (LNM) and distant metastases (DM) were immunostained for ER and GATA3, and assigned positive or negative status on the basis of Hscores.
