Overall survival (OS) is a composite clinical endpoint in hepatocellular carcinoma (HCC) due to the mutual influence of cirrhosis and active malignancy in dictating patient's mortality. The ALBI grade is a recently described index of liver dysfunction in hepatocellular carcinoma, based solely on albumin and bilirubin levels. Whilst accurate, this score lacks cross-validation, especially in intermediate stage HCC, where OS is highly heterogeneous. We evaluated the prognostic accuracy of the ALBI grade in estimating OS in a large, multi-centre study of 2426 patients, including a large proportion of intermediate stage patients treated with chemoembolization (n=1461) accrued from Europe, the United States and Asia. Analysis of survival by primary treatment modality confirmed the ALBI grade as a significant predictor of patient OS after surgical resection (p<0.001), transarterial chemoembolization (p<0.001) and sorafenib (p<0.001). Stratification by Barcelona Clinic Liver Cancer stage confirmed the independent prognostic value of the ALBI across the diverse stages of the disease, geographical regions of origin and time of recruitment to the study (p<0.001). In this large, multi-centre retrospective study, the ALBI grade satisfied the criteria for accuracy and reproducibility following statistical validation in Eastern and Western HCC patients, including those treated with chemoembolization. Consideration should be given to the ALBI grade as a stratifying biomarker of liver reserve in routine clinical practice. Liver failure is a key determinant influencing the natural history of hepatocellular carcinoma (HCC). In this large multi-centre study we externally validate a novel biomarker of liver functional reserve, the ALBI grade, across all the stages of HCC.

The staging of liver fibrosis is pivotal for defining the prognosis and indications for therapy in hepatitis C. Although liver biopsy remains the gold standard, several noninvasive methods are under evaluation for clinical use. The aim of this study was to validate the recently described sequential algorithm for fibrosis evaluation (SAFE) biopsy, which detects significant fibrosis (≥F2 by METAVIR) and cirrhosis (F4) by combining the AST‐to‐platelet ratio index and Fibrotest‐Fibrosure, thereby limiting liver biopsy to cases not adequately classifiable by noninvasive markers. Hepatitis C virus (HCV) patients (2035) were enrolled in nine locations in Europe and the United States. The diagnostic accuracy of SAFE biopsy versus histology, which is the gold standard, was investigated. The reduction in the need for liver biopsies achieved with SAFE biopsy was also assessed. SAFE biopsy identified significant fibrosis with 90.1% accuracy (area under the receiver operating characteristic curve = 0.89; 95% confidence interval, 0.87‐0.90) and reduced by 46.5% the number of liver biopsies needed. SAFE biopsy had 92.5% accuracy (area under the receiver operating characteristic curve = 0.92; 95% confidence interval, 0.89‐0.94) for the detection of cirrhosis, obviating 81.5% of liver biopsies. A third algorithm identified significant fibrosis and cirrhosis simultaneously with high accuracy and a 36% reduction in the need for liver biopsy. The patient's age and body mass index influenced the performance of SAFE biopsy, which was improved with adjusted Fibrotest‐Fibrosure cutoffs. Two hundred two cases (9.9%) had discordant results for significant fibrosis with SAFE biopsy versus histology, whereas 153 cases (7.5%) were discordant for cirrhosis detection; 71 of the former cases and 56 of the latter cases had a Fibroscan measurement within 2 months of histological evaluation. Fibroscan confirmed SAFE biopsy findings in 83.1% and 75%, respectively. Conclusion: SAFE biopsy is a rational and validated method for staging liver fibrosis in hepatitis C with a marked reduction in the need for liver biopsy. It is an attractive tool for large‐scale screening of HCV carriers. (HEPATOLOGY 2009.)
