Abstract

Prognosis of patients with advanced hepatocellular carcinoma (HCC) is under expectation. Life expectancy more than 3 months is one inclusion criteria for molecular targeted drugs in clinical trials. The main purpose of this research is to compare Model for End-Stage Liver Disease (MELD) and four MELD-based prognostic models in predicting the survival rate of advanced HCC patients. One hundred eighty-three patients with advanced HCC who were not amendable to standard anti-tumor therapy were retrospectively analyzed. Data were collected to classify patients according to MELD, Model for End-Stage Liver Disease with the incorporation of serum sodium (MELD-NA), Model for End-Stage Liver Disease to ascites and sodium (MELD-AS), integrated Model for End-Stage Liver Disease (iMELD), and Model for End-Stage Liver Disease to sodium (MESO) scores at diagnosis. 1-, 3-, and 6-month survivals were the end points used in the analysis. When predicting 1-month survival, MELD-AS, MELD, and MESO were the top 3 ranking staging systems. When predicting 3-month survival, area under the receiver operating characteristic curve (AUC) of MELD-AS is significantly higher than that of the other models (P < 0.05). When predicting 6-month survival, AUCs of MELD-AS and MELD-NA are significantly higher than those of the other models (P < 0.05). Cutoff point of MELD-AS is 23.11 with 40.5 % sensitivity and 93.8 % specificity at 1 month, 9.5 with 76.9 % sensitivity and 59.5 % specificity at 3 months, and 18.5 with 27.0 % sensitivity and 89.1 % specificity at 6 months. MELD-based scores of death group are significantly higher than those of survivors within 1 and 3 months (P < 0.001). Independent prognostic factors identified by multivariate analysis included persistent ascites, serum sodium, and thrombosis. MELD-AS is the best model in the prediction of short and intermediate survival among the five models for end-stage liver disease analyzed for Chinese advanced HCC patients.
