The densities of CD3+ T cells, CD8+ T cells, and CD163+ M2 cells were higher in squamous cell carcinoma (SCC) than in non-SCC types (P < 0.005, P < 0.037, and P < 0.025, respectively), whereas CD57+ cells were increased in non-SCC cervical cancer (P < 0.011) compared with SCC. Here, CD163 is linked to squamous cell carcinoma.
