[New scoring systems for severity outcome of liver cirrhosis and hepatocellular carcinoma: current issues concerning the Child-Turcotte-Pugh score and the Model of End-Stage Liver Disease (MELD) score].

It has been approximately 30 years since Child-Turcotte-Pugh score has been used as a predictor of mortality in patients with liver cirrhosis and hepatocellular carcinoma (HCC). Recently, new prognostic models such as Model for End-Stage Liver disease (MELD), Short- and Long-term Prognostic Indices (STPI and LTPI), Rockall score, and Emory score were proposed for predicting survival in patients with liver cirrhosis treated by transjugular intrahepatic portosystemic shunt (TIPS). In MELD scoring, three independent variables which showed a wide range of results including serum creatinine, serum bilirubin and international normalization ratio (INR) of prothrombin time were evaluated in log(e) scale in comparison with simply categorized-into-three scoring system of Child-Turcotte-Pugh.
