Comparison of albumin-bilirubin grade versus Child-Pugh score in predicting the outcome of transarterial chemoembolization for hepatocellular carcinoma using time-dependent ROC.

The Child-Pugh score has been used extensively to assess hepatic function and predict post-treatment outcomes in patients with hepatocellular carcinoma (HCC). Recently, the albumin-bilirubin (ALBI) grade has been put forward as an objective method of evaluating liver function and predicting overall survival (OS) in HCC patients. Transarterial chemoembolization (TACE) is considered to be effective in prolonging OS among intermediate-stage HCC patients. This study aimed to explore and compare the performance of ALBI grade and Child-Pugh score in predicting outcomes for HCC patients who underwent TACE. There were a total of 221 consecutive HCC patients enrolled in this study, all of whom received TACE and were enrolled retrospectively. The Kaplan-Meier method and time-dependent receiver operating curves (ROC) were used to estimate the discriminatory ability and survival prediction accuracy of ALBI grade and Child-Pugh score in predicting postoperative OS. Univariate and multivariate Cox regression analyses were performed to evaluate the prognostic factors for OS. Of the patients enrolled in the study, 106 (48.0%) were ALBI grade 1 and 115 (52.0%) were ALBI grade 2. Overall survival differed significantly between patients with ALBI-1 and ALBI-2 [hazard ratio (HR), 3.032; 95% CI, 2.019-4.555, P<0.001]. With regard to Child-Pugh scores, 160 (72.4%) patients had a score of A5 and 61 (27.6%) had a score of A6. There was also a difference in overall survival between patients with Child-Pugh-A5 and Child-Pugh-A6 (HR, 1.548; 95% CI, 1.066-2.247, P=0.022). In multivariate analyses, both ALBI grade and Child-Pugh score could significantly stratify the patients with different OS (HR, 2.994 and 1.545, P<0.001 and P=0.026 for ALBI grade and Child-Pugh score, respectively). Furthermore, time-dependent ROC analysis and its subgroup analyses demonstrated that the ALBI grade had a better discriminatory ability than Child-Pugh score in predicting survival. In stratifying prognosis for HCC patients who had received TACE therapy, the ALBI grade provided better prognostic performance and discrimination of liver function than Child-Pugh score. These results suggest that ALBI grade could provide an alternative liver function grading system for stratification of patients with HCC.

Comparison between Child-Pugh score and Albumin-Bilirubin grade in the prognosis of patients with HCC after liver resection using time-dependent ROC.

The Child-Pugh score is a scoring system used to measure liver function and predict postoperative outcomes in patients with hepatocellular carcinoma (HCC). Recently, the Albumin-Bilirubin (ALBI) grade has been proposed for the evaluation of hepatic reserve function in HCC. This study aimed to assess and compare the capability of ALBI grade and Child-Pugh score in predicting overall survival (OS). A total of 196 consecutive HCC patients who treated with hepatectomy were enrolled in this retrospective study. The prognostic values of ALBI grade and Child-Pugh score in predicting postoperative OS were respectively estimated using the Kaplan-Meier method and time-dependent receiver operating curves (ROC). Univariate and multivariate Cox regression analyses were performed to investigate the prognostic factors for OS. Stratified by the Albumin-Bilirubin (ALBI) system, there were 81 (41.3%) patients with grade 1 and 115 (58.7%) patients with grade 2. The cumulative 1-, 3-, 5-year OS rates in patients with ALBI-1 were 82.7%, 51.5% and 35.5%, respectively. For patients with ALBI-2, the cumulative 1-, 3-, 5-year OS rates were 57.6%, 19.4% and 0%, respectively. Based on the Child-Pugh classification, 136 (69.4%) patients had a score of 5, and 60 (30.6%) patients had a score of 6. Patients with Child-Pugh-A5 showed a better OS than those with Child-Pugh-A6, with respective OS at 1, 3 and 5 years (72.7%, 29.2%, 20.3% vs. 53.9%, 21.1%, 0%, Log-rank P<0.001). Besides, the ALBI grade revealed two prognostic groups within Child-Pugh-A5 (P<0.001), while the Child-Pugh score did not distinguish ALBI-2 in different prognostic groups (P=0.705). The multivariate analysis indicated that both ALBI grade and Child-Pugh score could significantly stratify the patients with different OS [hazard ratio (HR), 3.088 and 1.783; 95% confidence interval (CI), 1.985 to 4.805 and 1.272 to 2.731; P<0.001 and P=0.032 for ALBI grade and Child-Pugh score, respectively]. Additionally, time-dependent ROC analysis in the entire cohort proved that the ALBI grade had a better discriminatory ability than the Child-Pugh score in predicting survival, especially for long-term outcomes. According to the subgroup analyses, the ALBI grade had a better discriminatory ability and survival prediction accuracy in overall subsets than the Child-Pugh score for the prediction of OS. ALBI grade supplied better prognostic performance and distribution of liver function than Child-Pugh score in stratifying prognosis for HCC patients treated by hepatectomy. These results declared that ALBI grade could be an alternative liver function grading system for stratification in patients with HCC.

Comparison between Child-Pugh Score and albumin-bilirubin grade in patients treated with the combination therapy of transarterial chemoembolization and sorafenib for hepatocellular carcinoma.

Albumin-Bilirubin (ALBI) grade has been proposed for the evaluation of liver function in hepatocellular carcinoma (HCC). The combination therapy of transarterial chemoembolization (TACE) and sorafenib is widely used for HCC patients with preserved liver function; our study aimed to investigate and compare the discriminating values of ALBI grade and Child-Pugh score in overall survival (OS). A total of 173 HCC patients with preserved liver function (Child-Pugh A) were enrolled. The prognostic values of OS for ALBI grade and Child-Pugh score were separately investigated. In multivariate analyses, both ALBI grade and Child-Pugh score could significantly stratify the patients with different OS [adjusted hazard ratio (HR) 2.15 and 1.48, P<0.001 and P=0.035 for ALBI grade and Child-Pugh score]. In addition, time-dependent ROC analysis demonstrated that the ALBI grade had a better discriminatory ability than Child-Pugh score in predicting survival, especially for long-term outcomes. According to the subgroup analyses, the ALBI grade remained significant in more patient subsets and was more consistent than Child-Pugh score for the prediction of OS. ALBI grade was better than Child-Pugh score in stratifying prognosis for HCC patients with preserved liver function (Child-Pugh A) and treated by the combination therapy of TACE and sorafenib.

Validation and prognostic value of EZ-ALBI score in patients with intermediate-stage hepatocellular carcinoma treated with trans-arterial chemoembolization.

Heterogeneity of liver function and tumor burden in intermediate-stage hepatocellular carcinoma (HCC) results in different outcomes after transarterial chemoembolization (TACE). Easy albumin-bilirubin (EZ-ALBI), a simplified albumin-bilirubin (ALBI) score, has recently been proposed as a new prognostic score for HCC. This study aimed to validate the EZ-ALBI score and evaluate the impact of dynamic changes in patients with intermediate-stage HCC undergoing TACE. All patients with HCC treated with TACE at King Chulalongkorn Memorial Hospital, Bangkok, Thailand, between January 2015 and December 2019 were prospectively enrolled. Intermediate-stage HCC was defined as Barcelona Clinic Liver Cancer (BCLC) stage B or unresectable single HCC with size > 5 cm in BCLC stage A. EZ-ALBI and ALBI scores were calculated and stratified into three different grades. Overall survival (OS) and prognostic factors were assessed using the Kaplan-Meier curve and Cox proportional hazard model. Decision analysis curves were used to evaluate the clinical utility of the predictive scores. Among 672 patients with HCC treated with TACE, 166 patients with intermediate-stage HCC who met the eligibility criteria were enrolled. The median OS of all patients in the cohort was 21 months. A good correlation between the EZ-ALBI and ALBI scores was observed (correlation coefficient 1.000, p < 0.001). The baseline EZ-ALBI grades 1, 2, and 3 were 24.5%, 70%, and 5.5%, respectively. EZ-ALBI grade can stratify patients with significantly different prognoses (p = 0.002). Baseline EZ-ALBI grade 2, 3, and serum alpha-fetoprotein > 20 ng/ml were significantly associated with OS [hazard ratio (HR) 2.20 (95% confidence interval [CI] 1.24-3.88, p = 0.007), 3.26 (95% CI 1.24-8.57, p = 0.016), and 1.77 (95% CI 1.10-2.84, p = 0.018), respectively]. Following TACE, 42 (29.6%) patients had a worsening EZ-ALBI grade. However, the EZ-ALBI grade migration was not significantly correlated with OS. EZ-ALBI and ALBI score provided improved discriminatory ability (Harrell's concordance index 0.599 and 0.602, respectively) and better net benefit compared with Child-Turcotte-Pugh and Model for End-stage Liver Disease scores. The baseline EZ-ALBI score demonstrated good predictive performance for survival and a strong correlation with conventional ALBI scores. Both the EZ-ALBI and ALBI scores outperformed other prognostic models in patients with intermediate-stage HCC receiving TACE. However, the dynamic change in the EZ-ALBI grade after TACE was not associated with postprocedural survival.

Albumin-bilirubin index and platelet-albumin-bilirubin index contribute to identifying survival benefit candidates in patients with hepatocellular carcinoma and Child-Pugh grade A undergoing transcatheter arterial chemoembolization with sorafenib treatmen

Combined therapy of transcatheter arterial chemoembolization (TACE) with sorafenib is used for a large number of patients with intermediate-stage or advanced-stage hepatocellular carcinoma (HCC), but its implementation is limited by the evaluation of pre-treatment liver function reserve. This study aimed to validate the performance of the albumin-bilirubin index (ALBI) and platelet-albumin-bilirubin index (PALBI) in predicting survival benefits in patients with HCC and Child-Pugh grade A receiving TACE combined with sorafenib treatment. From 2004 to 2018, 418 patients with intermediate/advanced-stage HCC and Child-Pugh grade A receiving TACE combined with sorafenib treatment were retrospectively enrolled. The predictive performance of ALBI and PALBI was explored by survival analysis and receiver operating characteristic curve (ROC) analysis. The median overall survival (mOS) was 24 and 12 months in patients with ALBI grade 1 and grade 2, respectively. The mOS of patients with PALBI grade 1, grade 2, and grade 3 was 23, 16, and 7 months, respectively. The multivariate analysis showed that ALBI grade 2 [hazard ratio (HR) =1.39, 95% confidence interval (CI): 1.11-1.74] and PALBI grade 3 (HR =3.72, 95% CI: 2.26-6.06) were associated with unfavorable prognosis. The ROC analysis revealed that ALBI and PALBI scores had better prediction performance compared with the Child-Pugh score. Subgroup analysis confirmed that by using ALBI or PALBI, patients could be stratified into subgroups with different liver function reserves and distinctive prognosis, regardless of Barcelona Clinic Liver Cancer (BCLC) stage, combination modality, or α-fetoprotein (AFP) levels. Both ALBI and PALBI could predict prognosis in patients with HCC and Child-Pugh grade A receiving TACE and sorafenib. Patients with ALBI or PALBI grade 1 harbored a more favorable survival outcome compared with those with ALBI or PALBI grade 2-3, and hence should be recommended as the best candidates for TACE combined with sorafenib treatment.
