Abstract
BACKGROUND: We aimed to investigate the use of novel serum biomarkers for predicting the recurrence and survival of patients with hepatitis B virus (HBV)-related early hepatocellular carcinoma (HCC) after hepatic resection or radiofrequency ablation (RFA). METHODS: One hundred and five patients with HBV-related HCC, who fulfilled the Milan criteria without vascular invasion and underwent hepatic resection or RFA, were followed-up for a median duration of 52months. Pretreatment serum concentrations of 16 cytokines including interleukin-6 (IL-6) were measured by using a Luminex 200 system. The measured serum cytokines and several clinical factors were analyzed retrospectively. RESULTS: Univariate analysis showed that patients with lower pretreatment serum levels of IL-10, IL-6, monocyte chemoattractant protein-1, and tumor necrosis factor-α had significantly shorter disease-free survival (DFS) than those with higher levels. Multivariate analysis revealed that a low serum IL-6 level (⩽33.00pg/mL; hazard ratio [HR]=5.39; 95% confidence interval [CI]=1.27-22.93; P=0.022), low platelet count (<100×10(9)/L; HR=2.23; 95% CI=1.28-3.89; P=0.005), and low serum albumin level (⩽3.5g/L; HR=2.26; 95% CI=1.28-3.97; P=0.005) had a negative prognostic impact on DFS. In the analysis for overall survival, a low serum platelet level (<100×10(9)/L; HR=2.80; 95% CI=1.31-5.99; P=0.008) and multiple tumor (⩾2; HR=4.05; 95% CI=1.56-10.48; P=0.004) showed a negative prognostic impact on the overall survival. CONCLUSION: A low serum IL-6 level is, in addition to low platelet count and low serum albumin level, an independent prognostic factor for DFS in patients with HBV-related early HCC who underwent hepatic resection or RFA with curative intention.
