Kaplan–Meier survival analysis results showed that the high TP expression significantly affected the survival prognosis of patients with HCC with clinical parameters of stage ≥II, metastasis or CEA content >3.4 ng/mL, AFP content >400 ng/mL, or alanine aminotransferase content >38 U/L (Figure S1). This evidence concerns the gene CEACAM5 and hepatocellular carcinoma.
