By staining consecutive sections in 87 HCC patients (Figure 5A), a correlation analysis revealed that significant positive correlations were found between the density of intratumoral IL-17-producing cells and MVD (r = 0.567; p < 0.001), as well as between the densities of intratumoral CD66b+ neutrophils and IL-17+ cells (r = 0.630; p < 0.001; Figure 5B). The gene discussed is IL17A; the disease is hepatocellular carcinoma.
