Abstract
Purpose
The aspartate aminotransferase to platelet ratio index (APRI) and fibrosis-4 (FIB-4) index were developed as a non-invasive parameter for predicting liver fibrosis. This study aimed to validate the APRI and FIB-4 indexes in patients treated with curative therapy for non-B non-C (NBNC) hepatocellular carcinoma (HCC).
Methods
Accumulated database comprising 399 patients who underwent hepatectomy was reviewed retrospectively. Analyses were performed to evaluate whether the APRI and FIB-4 indexes are predictors of liver cirrhosis and/or the prognosis in patients with NBNC-HCC. Forty-seven patients with NBNC-HCC who underwent curative radiofrequency ablation therapy (RFA) in the same period were enrolled as the validation set.
Results
The APRI and FIB-4 indexes were significantly higher in the cirrhosis group than in the no-cirrhosis group (P = 0.001 and P < 0.001, respectively). A receiver operating characteristic curve analysis showed that the FIB-4 index was more accurate in predicting background liver cirrhosis than the APRI. According to a multivariate analysis, an FIB-4 index larger than 2.7 (hazard ratio 2.11 and 2.21, 95 % confidence interval 1.06–4.18 and 1.38–3.54, P = 0.033 and P = 0.001) remained significant independent predictors of overall and recurrence-free survival, respectively.
Conclusions
The present findings showed that the FIB-4 index is a significant predictor of background liver cirrhosis and the prognosis after curative resection for NBNB-HCC.
