To determine the potential role of CXCL17 in immune cell regulation in HCC, we performed comprehensive analyses of immune cell infiltration and examined the correlation between CXCL17 expression and CD4+, CD8+, CD20+, CD57+, CD15+, and CD68+ cell density in HCC tissues using the Pearson correlation test. This evidence concerns the gene FUT4 and hepatocellular carcinoma.
