Prognostic scoring system for radiofrequency ablation: Usefulness of albumin-bilirubin (albi)-grade

Abstract

Background/Aim: We evaluated the efficacy of albumin-bilirubin (ALBI)-grade in grading the patients by hepatic function and for predicting prognosis of hepatocellular carcinoma (HCC) who treated with radiofrequency ablation (RFA). Method: From 2000 to 2015, 1720 naïve HCC, who were treated with RFA, were enrolled. We made ALBI-T score which was consisted of ALBI grade and TNM stage of LCSGJ like as Japan Integrated Staging (JIS) score. We compared JIS and ALBI-T score, retrospectively. Results: Median survival time (MST) of ALBI-T score was better than that of JIS score (0/1/2/3/4/5=141.2/75.8/54.8/39.1/18.8/-vs.109.5/66.9/50.2/36.2/16.1/- months). ALBI-T score (0/1/2/3) showed better prognosis than those with corresponding JIS score significantly (P values of 0, 1, 2 and 3: 0.011, 0.001, 0.017 and 0.025). Conclusion: ALBI-grade was thought to be better methods to distinguish better hepatic function than Child-Pugh classification, and ALBI-T score was thought to have good predicting value for prognosis of HCC treated with RFA.
