Abstract:Objective To explore the diagnostic effect of soluble B7-H3 (sB7-H3), interleukin 17 (IL-17) and interleukin 8 (IL-8) on primary liver cancer. Methods Forty-five cases of primary liver cancer patients treated in our hospital between January 2014 and January 2015 were selected as observation group, and 45 healthy volunteers having health examination during the same period were selected as control group. The peripheral blood serum samples were collected from the two groups. Serum sB7-H3, IL-17 and IL-8 levels were detected by enzymelinked immunosorbent assay. The effect of sB7-H3, IL-17 and IL-8 in the diagnosis of primary liver cancer was analyzed. Results The serum sB7-H3, IL-17 and IL-8 levels of the observation group were significantly higher than those of the control group (P < 0.05). In both groups, sB7-H3, IL-17 and IL-8 levels were not statistically different between the patients with different genders and age (P > 0.05). IL-17 level of the patients with clinical stage I and II was higher than that of the patients with clinical stage III, sB7-H3 and IL-8 levels of the patients with clinical stage I and II were lower than those of the patients with clinical stage III (P < 0.05). sB7-H3 and IL-8 levels of the patients with distant metastasis were higher than those of the patients without distant metastasis, IL-17 level was lower than that of the patients without distant metastasis, the differences were statistically significant (P < 0.05).Serum sB7-H3 level and IL-8 level were not correlated in the patients with primary hepatocellular carcinoma, serum sB7-H3 level had a positive correlation with serum IL-17 level, and IL-17 level and IL-8 level were negatively correlated. The risks of hepatocellular carcinoma metastasis in the patients with high levels of serum sB7-H3, IL-8 and IL-17 were respectively 1.001, 1.030 and 1.003 times those in the patients with low levels of serum sB7-H3, IL-8 and IL-17. Logistic regression prediction model showed that serum sB7-H3, IL-8 and IL-17 levels could be used to diagnose liver cancer. Conclusions sB7-H3 level in the serum of the patients with primary liver cancer is positively correlated with IL-17, and IL-17 level is negatively correlated with the level of IL-8. Serum sB7-H3, IL-8 and IL-17 levels can be used to diagnose primary hepatocellular carcinoma.
