Evaluation of Pretreatment Albumin–Bilirubin Grade as a Better Prognostic Factor Compared to Child–Pugh Classification in Patients with Hepatocellular Carcinoma Receiving Transarterial Chemoembolization Combined with Radiotherapy

This study assessed the use of pretreatment albumin–-bilirubin (ALBI) grade as a prognostic factor in patients with hepatocellular carcinoma (HCC) receiving combined transarterial chemoembolization (TACE) and radiotherapy (RT). Patients who underwent RT following TACE between January 2011 and December 2020 were analyzed retrospectively. The survival outcomes of patients in regard to the ALBI grade and Child–Pugh (C–P) classification were evaluated. A total of 73 patients with a median follow-up of 16.3 months were included. Thirty-three (45.2%) and forty patients (54.8%) were categorized into ALBI grades 1 and 2–3, respectively, while sixty-four (87.7%) and nine (12.3%) were C–P classes A and B, respectively (p = 0.003). The median progression-free survival (PFS) and overall survival (OS) for ALBI grade 1 vs. 2–3 were 8.6 months vs. 5.0 months (p = 0.016) and 27.0 months vs. 15.9 months (p = 0.006), respectively. The median PFS and OS for C–P class A vs. B were 6.3 months vs. 6.1 months (p = 0.265) and 24.8 months vs. 19.0 months (p = 0.630), respectively. A multivariate analysis showed that ALBI grades 2–3 were significantly associated with worse PFS (p = 0.035) and OS (p = 0.021). In conclusion, the ALBI grade could be a good prognosticator in HCC patients who were treated with combined TACE-RT.
