As shown in Figure 3, patients with high infiltrating density of CD57+ NK cells and low infiltrating density of CD68+ macrophages in tumor nest had a significantly better OS compared with the patients with low infiltrating density of CD57+ NK cells and high infiltrating density of CD68+ macrophages (median OS: 4.60 vs. 1.30 years, P = 0.0008). This evidence concerns the gene CD68 and neoplasm.
