CEP192 and hepatocellular carcinoma: To further investigate the association between CEP192 expression and the tumor microenvironment of HCC, we calculated the immune score, stromal score, ESTIMATE score (that represented the sum of the immune score and stromal score and inferred tumor purity), and tumor purity using the ESTIMATE algorithm in 611 HCC patients downloaded from TCGA (n = 371) and ICGC (n = 240).
