After analyzing, there was a significantly positive correlation between the HCC-parenchyma ratios of arterial BF and level of circulating IL-8, indicating a higher IL-8 level in circulation was associated with higher arterial BF in HCC relative to the surrounding parenchyma (Figure 5 and Table 2, p = 0.0357). Here, CXCL8 is linked to hepatocellular carcinoma.
