Axillary node status according to size and grade of tumour and presence of lymphovascular invasion

Grade	LVI	Number of positive nodes/ total nodes (%)
		Tumour < 11 mm	Tumour 15 – 11 mm	Tumour >15 mm	All tumours
1	LVI+	0/3 (0%)	1/1 (100%)	0	1/4 (25%)
n = 55	LVI-	0/30 (0%)	2/15 (13%)	2/6 (33%)	4/51 (8%)
2	LVI+	1/2 (50%)	1/3 (33%)	4/4 (100%)	6/9 (67%)
n = 67	LVI-	1/22 (5%)	1/27 (4%)	5/9 (56%)	7/58 (12%)
3	LVI+	0	0/2 (0%)	1/2 (50%)	1/4 (25%)
n = 20	LVI-	2/7 (29%)	0/5 (0%)	1/4 (25%)	3/16 (19%)

G = grade (1–3)

LVI = Lymphovascular invasion (positive (+) or negative (-)
