Appraisal of a newly developed ALBI-sarcopenia score as a prognostic marker in patients with hepatocellular carcinoma

Objective This study aimed to evaluate the impact of the combined Albumin–bilirubin (ALBI)/sarcopenia score as a newly developed prognostic model for hepatocellular carcinoma (HCC), with a focus on its utility in predicting mortality. Methods This prospective study was conducted on HCC patients who were followed for 1 year or until death. Sarcopenia was assessed radiologically by computed tomography at the level of L3. The study consisted of two sets: a development set in which the new ALBI-sarcopenia score was created, comprising 262 HCC patients, followed by an internal validation set with 100 patients. Results The development cohort primarily included males (69.5%), aged 59.6 ± 8.09 years. In patients with sarcopenia, the ALBI score was −2.03 ± 0.42 ( P < 0.006), the model for end-stage liver disease (MELD) score was 11.29 ± 2.43 ( P < 0.001*), and the MELD-sarcopenia score was 21.29 ± 2.43 ( P < 0.001*). The distribution of barcelona clinic liver cancer (BCLC) staging was as follows: BCLC A 18 (15.9%), BCLC B 63 (55.8%) and BCLC C 32 (28.3%) ( P < 0.001*), with a notable association with higher mortality ( P < 0.001). Multivariate analysis identified sarcopenia and ALBI scores as independent predictors of mortality in HCC ( P < 0.001*). In the development set, the ALBI-sarcopenia score successfully predicted mortality at a cutoff >−11 with an area under a curve of 0.837 (95% CI, 0.784–0.889), while in the validation set, it predicted mortality at a cutoff >−11.55 with an area under a curve of 0.842 (95% CI, 0.753–0.930). Conclusion The newly introduced ALBI-sarcopenia score has demonstrated superior effectiveness in comparison to MELD-sarcopenia score, overcoming the shortcomings associated MELD score in forecasting outcomes for patients with HCC.
