Modified CLIP score with albumin-bilirubin grade in relation to prognostic value in HBV-related hepatocellular carcinoma patients treated with transcatheter arterial chemoembolization therapy.

Abstract

480 Background: Child-Pugh grade is widely used to assess hepatic function reserve, but it is relatively subjective for assessment of hepatic encephalopathy. A newly developed scoring system combining albumin and bilirubin, called ALBI grade, aims to assess liver function objectively. In prognosis prediction of hepatocellular carcinoma (HCC), The Cancer of the Liver Italian Program (CLIP) score is commonly used in clinical practice and includes Child-Pugh evaluation. We substituted ALBI grade for Child-Pugh grade to establish ALBI-CLIP system and conducted this study to validate the prognostic value of ALBI -CLIP in HBV-related HCC patients after TACE therapy. Methods: We retrospectively analyzed HBV-related HCC patients who received TACE therapy. Baseline data were collected and evaluated. Child-Pugh grade and ALBI grade were integrated into CLIP and ALBI-CLIP systems, respectively. Univariate and multivariate analyses were conducted to identify independent prognostic factors for overall survival. Comparisons of receiver operating characteristic (ROC) curves and likelihood ratio test (LRT) were used to compare the value of ALBI-CLIP, CLIP and TNM staging systems in predicting survival. Results: A total of 207 patients were included. 153 (73.9%) and 54 (26.1%) patients were classified as Child-Pugh grade A and B, respectively. But according to ALBI grade, 57 (27.5%), 136 (65.7%) and 14 (6.8%) of them were correspondingly divided into Grade 1, 2 and 3. Comparisons of ROC curves showed that ALBI-CLIP and CLIP had similar areas under the curve, both of which were larger than that of TNM system in predicting 3-month, 6-month, 1-year and 2-year survival. LRT indicated that both ALBI-CLIP and CLIP had larger χ2 values and smaller values of Akaike information criterion (AIC), compared with TNM system (χ2 = 29.771, 29.479, 9.105; AIC = 858.215, 858.069, 879.410 for ALBI-CLIP, CLIP and TNM, respectively). Conclusions: Our current study suggested that modified CLIP score with albumin-bilirubin grade retained prognostic value in HBV-related HCC treated with TACE therapy.
