Abstract: Objective To investigate the clinical application of serum interleukin-6 (IL-6)and interleukin-22 (IL-22) levels in predicting the recurrence of hepatitis B virus (HBV)-related early hepatocellular carcinoma (HCC) after receiving microwave ablation (MWA).Methods Preoperative peripheral blood samples were collected in 49 patients with early-stage HBV-related HCC,and serum concentrations of IL-6 and IL-22 were measured by using ELISA.Thirty healthy volunteers were recruited and used as the control group.The xtile software was used to define the best cut-off value,and the IL-6 and IL-22 levels were divided into highlevel group and low-level group.The tumor-free survivals of high-level and low-level groups were analyzed with Kaplan-Meier analysis,log rank test was adopted to determine the difference,and Cox regression model was employed to screen the risk factors affecting HBV-related HCC recurrence.Results The serum IL-6 and IL-22 levels of HCC group were 13.20 pg/ml (11.87-15.79 pg/ml) and 42.18 pg/ml (34.39-57.44 pg/ml) respectively,which were significantly higher than 10.47 pg/ml (9.50-13.82 pg/ml) and 25.45 pg/ml (22.31-30.12 pg/ml) of the control group (P=0.001 and P＜0.001 respectively).Kaplan-Meier analysis revealed that preoperative lower IL-6,higher total bilirubin and lower albumin levels indicated a shorter disease-free survival (DFS),and IL-22 levels had no statistically significant effect on the recurrence of HCC.Cox regression multivariate analysis showed that lower serum IL-6 level (≤ 13.2 pg/ml;hazard ratio=3.721;95％ CI=1.674-8.272;P=0.001) and lower serum albumin level (≤41.0 g/L;hazard mtio=2.085;95％CI=1.101-3.950;P=0.024) were independent risk factors affecting HBV-related HCC recurrence Conclusion Preoperative serum IL-6 level and serum albumin level can be used as the predictors of HCC recurrence in patients with HBV-related early HCC who are receiving MWA treatment.(J Intervent Radiol,2017,26:232-236)
