CEACAM8 and neoplasm: Finally, groups of three and four different immune cell markers were analyzed: both high infiltration of CD3+/CD8+/CD20+ TILs (OS p = 0.002, PFS p = 0.0003) and high infiltration of CD3+/CD8+/CD20+/CD66b+ tumor-infiltrating leukocytes (OS p = 0.009, PFS p = 0.001) correlated significantly with improved survival in the Kaplan-Meier analysis (Figure 2 and Figure 3).
