Core Tip

Core tip: This is the first study to apply the barcelona clinic liver cancer (BCLC) B subclassification in a survival analysis for hepatocellular carcinoma patients after transarterial embolization. Were observed significant differences in the mean survival rates among B1, B2, B3 and B4 patients. The BCLC B sub-staging system could be an additional tool for accessing prognosis in the post-embolization survival rates of hepatocellular carcinoma patients.
