Prognostic Accuracy of 12 Liver Staging Systems in Patients with Unresectable Hepatocellular Carcinoma Treated with Transarterial Chemoembolization

Child-Pugh nominal, CUPI, and Tokyo scores provide the best prognostic accuracy among the systems studied. However, those of the Tokyo and CUPI methods are artificially enhanced because of their greater number of staging levels. The Child-Pugh nominal liver staging system is the most accurate in predicting survival of patients with unresectable HCC treated with TACE, and it is recommended that it be adopted as the standard for HCC staging in such patients.
