Intercostobrachial Nerves as a Novel Anatomic Landmark for Dividing the Axillary Space in Lymph Node Dissection

Table 5

Number of patients with micro-metastasis (macro-metastasis-negative nodes stained with CK-22) in different node groups.

	Pre-operative evaluation	Lower LN Group		Upper LN group	Post-operative evaluation
		SLN	Non-SLN
LNMM (−)	34	41	29	50	28
LNMM (+)	19	12	24	3	25
Number of samples	53	53	53	53	53

LNMM (−): micro-metastasis negative; LNMM (+): micro-metastasis positive; SLN: sentinel lymph nodes group; non-SLN: non-sentinel lymph nodes group.
