ALDH18A1 and neoplasm: The significant associations between the beneficial pathological responses (GPR and pCR) in the tumour microenvironment (primary and ALN metastases) and key innate immune cells (CD163+ TIMs, circulating PMN neutrophils, and DCs/subsets) complement our findings with NK cells and are an important contribution to the understanding of putative anticancer immune responses in NAC, resulting in immune-mediated tumour cell death.
