CD1A and neoplasm: We found that low expression of conventional dendritic cell markers (CD1a and FCER1A) was associated with pCR, potentially affecting the overall patient survival in TNBC; however, a previous study [19] reported no significant association between the levels of CD1a + tumour-infiltrating dendritic cells and pCR in either the primary tumours or axillary lymph node metastasis.
