IL10 and hepatocellular carcinoma: Table 2 indicates the frequency of genotypes noted in studied groups. Overall, 33 patients with HCC had TT genotype, 56 had CT genotype, and 11 had CC genotype. Of the patients with HCV infection, 60 had TT genotype, 24 had CT genotype, and 16 had CC genotype. These results indicated that CT genotype is the most common genotype among patients with HCC. Figure 2 shows the correlation between different drug regimens and IL10 genotypes.
