Validation of the “Six-and-Twelve” Prognostic Score in Transarterial Chemoembolization–Treated Hepatocellular Carcinoma Patients

The "six-and-twelve" prognostic score was proposed recently to predict survival rate in patients with unresectable hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE). However, it has not been validated externally. We validated this score and previous prognostic scores in Thai HCC patients treated with TACE.
