Axillary lymph node evaluation by PET/CT (mean ± SD)

	Metastasis-positive	Negative (+ITC)
	(n = 69)	(n = 102)
Age (years)	56.7 ± 13.6	61.7 ± 14.4
Tumor size (mm)	23.9 ± 12.6a	18.7 ± 10.4
SUV-LN	2.289 ± 2.425a	0.841 ± 0.288
SUV-T	6.165 ± 3.871a	3.954 ± 3.524
NT ratio	0.5 ± 0.707b	0.316 ± 0.209

Patients with metastasis-positive nodes (n = 69) were compared to those with metastasis-negative nodes (n = 102). SD: Standard division. The node-negative group included those diagnosed with isolated tumor cells (ITC).

^a P <0.01.

^b P = 0.041 vs. the node-negative group.
