The Differential Contribution of the Innate Immune System to a Good Pathological Response in the Breast and Axillary Lymph Nodes Induced by Neoadjuvant Chemotherapy in Women with Large and Locally Advanced Breast Cancers

Table 3

Analyses of CD163⁺ macrophages in metastatic tumours in ALNs in women with LLABCs and subsequent PCR following NAC.

	Groups	Pre-NAC
		Low infiltration (n)	High infiltration (n)	Pearson chi-square value (PCR versus non-PCR)	value
CD163^+ macrophages ()	Pathological complete response (PCR, )	0	9	8.811	0.003
	Nonpathological complete response (non-PCR, )	7	4

ALNs: axillary lymph nodes; LLABCs: large and locally advanced breast cancers; NAC: neoadjuvant chemotherapy; statistically significant.
