Background  Hepatoma up-regulated protein (HURP) is a component of the chromatin-dependent pathway for spindle assembly. We examined the prognostic predictive value of HURP in human hepatocellular carcinoma (HCC).    Methods  HURP expression was evaluated by immunocytochemistry of fine needle aspirated hepatoma cells in 97 HCC patients with Barcelona Clinic Liver Cancer (BCLC) stage A. Subsequently, these patients underwent partial hepatectomy (n = 18) or radiofrequency ablation (n = 79) and were followed for 2 to 35 months. The clinicopathological parameters were submitted for survival analysis.    Results  HURP expression in aspirated HCC cells was detected in 19.6% patients. Kaplan-Meier survival analysis showed that positive HURP expression ( P  = 0.023), cytological grading ≥3 ( P  = 0.008), AFP ≥35 ng/mL ( P  = 0.039), bilirubin ≥1.3 mg/dL ( P  = 0.010), AST ≥50 U/L ( P  = 0.003) and ALT ≥35 U/L ( P  = 0.005) were all associated with a shorter disease-free survival. A stepwise multivariate Cox proportional hazard model revealed that positive HURP expression (HR, 2.334; 95% CI, 1.165–4.679,  P  = 0.017), AST ≥50 U/L (HR, 3.697; 95% CI, 1.868–7.319,  p <0.001), cytological grade ≥3 (HR, 4.249; 95% CI, 2.061–8.759,  P <0.001) and tumor number >1 (HR, 2.633; 95% CI, 1.212–5.722,  P  = 0.014) were independent predictors for disease-free survival. By combining the 4 independent predictors, patients with different risk scores (RS) showed distinguishable disease-free survival (RS≤1 vs. RS = 2,  P  = 0.001; RS = 2 vs. RS = 3, P<0.001). In contrast, the patients cannot be separated into prognosis distinguishable subgroups by using AJCC/UICC TNM staging system.    Conclusion  HCC patients with BCLC stage A can be separated into three prognosis-distinguishable groups by use of a risk score that is based upon HURP expression in aspirated HCC cells, ALT, cytological grade and tumor number.
