A staging system for hepatocellular carcinoma was reported from Italy (CLIP). In this study, we evaluate the CLIP scoring system and establish a new scoring system for predicting the prognosis of patients with hepatocellular carcinoma. Patients (n=141) who were diagnosed and who underwent initial treatment at our single institution were recruited retrospectively into this study. We evaluated markers for prognosis, using a stratified Cox proportional hazard regression model and Kaplan-Meier survival analysis. CLIP score differentiated patients with different survival experiences by Kaplan-Meier estimated survival analysis. However, with respect the CLIP score, more than two thirds of patients were included in the early stage (CLIP 0-1), and the group with better prognosis than the survival rate of all patients was the only one with CLIP 0. Multivariate analysis revealed that des-γ-carboxy prothrombin (DCP) ≥100 mAU/ml (relative risk, 2.06; P=0.0218) was statistically significant as a predictor of poor survival. A new prognostic scoring system included DCP classified patients to 6 well-balanced groups (score 0-5). The new prognostic scoring system 0 group (14.9% of the cohort) and the CLIP score 0 group (34.0% of the cohort) had a median survival of 66.9 and 61.6 months. The new prognostic scoring system performs better for prediction of survival than either the CLIP score or the Child-Pugh stage. In conclusion, the described scoring system provides more accurate prognostic information than the CLIP scoring system. It may help physicians decide more appropriate clinical and therapeutic management.
