DCN and neoplasm: After testing the hazard ratios for death and recurrence, respectively, in relation to the number of tumour‐interacting marker‐defined immune cells in univariable Cox regression analysis (supplementary material, File S19), the prognostic value of CD20+DCN+ B cells and CD4+DCN+ T cells was further investigated in Kaplan–Meier analysis applying the optimal prognostic cut‐off for each immune cell subset (Figure 5A, B).
