Immunohistochemical labeling of GATA3 in metastatic mammary carcinomas from matched cohorts (SPC and APC, n = 30)

Tumor type	n	GATA3					Total positive
		0	1+	2+	3+	4+
Total	30	4	2	4	0	20	26/30 (87%)
Luminal A–type carcinoma	13	0	0	0	0	13	13/13 (100%)
Luminal B–type carcinoma	0	–	–	–	–	–	–
Luminal loss carcinoma	5	0	0	0	0	5	5/5 (100%)
HER-2–type carcinoma	3	0	0	2	0	1	3/3 (100%)
TNC	9	4	2	2	0	1	5/9 (56%)

NOTE. Nuclear GATA3 labeling is defined as 0 (0–5%), 1+ (6%–25%), 2+ (25%–50%), 3+ (50%–75%), and 4+ (>75%).
