CCR5 (P=0.022, adjusted P=0.021, Table 1 and Figure 3B) and CCR7 (P=0.021, adjusted P=0.039, Table 1 and Figure 3C) were both found to be significantly correlated with the OS of the HCC patients in the GSE14520 cohort, using either the Cox proportional hazards model or the Kaplan-Meier method. Here, CCR7 is linked to hepatocellular carcinoma.
