Incorporating albumin-bilirubin grade and up-to-seven criteria to predict outcomes of patients with intermediate stage hepatocellular carcinoma after transarterial (chemo)embolization

This study is to use albumin-bilirubin (ALBI) grade and up-to-7 (UT7) criteria to assess outcomes of patients with intermediate stage hepatocellular carcinoma (HCC) after transarterial (chemo)embolization (TA(C)E).Between January 2012 and January 2019, newly diagnosed intermediate HCC patients underwent TA(C)E were enrolled and analyzed. The demographics, clinical characteristics and survival were obtained from medical chart reviews.A total of 359 patients were enrolled and 30.4% of them were within UT7 criteria (UT7 (-)). There were 36.5%, 59.3%, and 4.2% of the patients with ALBI grade I, II, and III, respectively. Beyond UT7 (UT7 (+)) and ALBI grade II/III were associated with overall mortality in multivariate analysis. Based on ALBI grade I/II/III and UT7 -/+, patients were classified into six groups as ALBI grade I plus UT7 (-), II plus UT7 (-), III plus UT7 (-), I plus UT7 (+), II plus UT7 (+), and III plus UT7(+). Distributions of median survival were 47.5, 32.9, 15, 34.3, 16.7 and 14.3 months, respectively. Patients with statistically insignificant survivals were further combined. Patients with ALBI grade I plus UT7 (-) were reclassified as ALBI-U class I, whereas ALBI grade II plus UT7 (-) and I plus UT7 (+) were ALBI-U class II, and the others were ALBI-U class III. There were 8.4%, 48.7%, and 42.9% of patients in ALBI-U class I, II, and III, respectively. The 5-year survival rate was 48.8%, 22.5%, and 13.7% in ALBI-U class I, II, and III, respectively (p < 0.01).ALBI-U classification was useful in predicting outcomes of patient with intermediate stage HCC after TA(C)E.
