Moreover, the survival analysis for patients with different tumor stage revealed that the high CCNB1 expression level was associated with shorter survival time compared with the low CCNB1 expression level in HCC patients with tumor stage 1 (log-rank P = 0.0088, Figure 4(g)), tumor stage 2 (log-rank P = 0.0071, Figure 4(h)), and tumor stage 3 (log-rank P = 0.0048, Figure 4(i)). Here, CCNB1 is linked to hepatocellular carcinoma.
