Kaplan‐Meier analysis revealed that patients with HCC with high exosomal LUCAT‐1 levels had a significantly shorter overall survival (OS) compared to those with low exosomal LUCAT‐1 levels (Figure 5D, HR 2.920 [95% confidence interval (CI) 1.860 to 4.584]). This evidence concerns the gene LUCAT1 and hepatocellular carcinoma.
