ALB and hepatocellular carcinoma: MIR22HG was demonstrated to be negatively correlated with T classification (P = 0.0381) and Child‐Pugh score (P = 0.0135) of HCC (Figure 4A,B), and CTC‐297N7.9 was negatively associated with ECOG PS of patients (P = 0.0444), the grade (P = 0.0059), T classification (P = 0.0216), and TNM stage (P = 0.0087) of tumors, and the serum levels of ALB (P = 0.0121) (Figure 4E‐I).
