Numbers of T lymphocytes (CD3+), helper T cells (CD3 + CD4+), tumor-associated macrophages (TAM; CD68+), activated natural killer cells (CD57 + granzyme B + CD45RO−), memory antigen experienced cells (CD45RO + PD-1+), and antigen experienced PD-1+ cells as well as PD-L1+ malignant cells were higher in the NCT group than in the non-NCT group. Here, CD68 is linked to neoplasm.
