WASHC2C and hepatocellular carcinoma: Subsequently, we statistically analyzed pathological parameters such as tumor size, TNM stage, and vascular invasion, and postoperative follow-up data of HCC patients in the FAM21C low-expression and high-expression groups (Supplementary Table 1), and the results suggested that the tumor diameter of HCC in the FAM21C high-expression group was significantly greater than in the low-expression group (8.7 ± 0.6 cm vs. 6.8± 0.5 cm, P=0.0192) (Figure 2C).
