Fibroscan and FIB-4 Assessment Versus Lymphocyte / Monocyte Ratio as Predictors of Post-Hepatectomy Liver Failure in HCV Egyptian Patients with Hepatocellular Carcinoma

Background: Post-hepatectomy liver failure (PHLF) is the most leading cause of mortality in patients diagnosed with hepatocellular carcinoma (HCC) and undergoing resection of the affected part of the liver. Objectives: This research aimed to determine the value of the lymphocyte to monocyte ratio (LMR), fibrosis score 4 (FIB-4) and liver stiffness measurements (LSM) using Fibroscan as pre-operative predictors of PHLF in Egyptian patients with post- hepatitis C virus (HCV) liver cirrhosis and HCC. Methods: In this prospective cohort study definition of PHLF was done according to the “50-50 criteria”. Multivariate analysis was done to identify PHLF independent predictors. The predictive accuracy of the pre-operative LMR, FIB-4 and LSM with Fibroscan were evaluated by receiver operating characteristic (ROC) curve. Results: Enrollment of fifty Egyptian patients was done. 14 patients (28%) experienced PHLF. The presence of oesophageal varices, serum AST, serum albumin, LMR, FIB-4 score, and LSM (P<0.05) were independent pre-operative predictors for PHLF. According to ROC curve analysis, LMR yielded the best accuracy for predicting PHLF at cutoff <3.33 [AUC = 0.940; sensitivity = 93.65%; specificity = 94.44%; positive predictive value = 86.67%; negative predictive value = 97.14%]. FIB-4 score and LSM had lower AUC (0.886 and 0.875) respectively. Conclusion: The pre-operative LMR has a higher predictive ability for PHLF in patients with HCV-related HCC undergoing hepatectomy compared with FIB-4 score and LSM using Fibroscan.
