BACKGROUND AND STUDY AIMS: To investigate whether the measurement of liver stiffness (LSM) using fibroscan and the serum Cancer Stem Cells (CSC): Ep-CAM and cytokeratin-19, could predict the recurrence of hepatocellular carcinoma (HCC) and their impact on clinical outcome and overall survival.

PATIENTS AND METHODS: This is a prospective study, including 179 HCV-related HCC patients. All patients were treated following the BCLC guidelines. All HCC patients had transient elastography, measurements of Ep-CAM and cytokeratin-19 before and six months post-treatment. We looked for predictors of recurrence and performed a survival analysis using Kaplan-Meier estimates.

RESULTS: TACE was the most common procedure (77.1\%), followed by microwave ablation (15.6\%). Complete ablation was achieved in 97 patients; 55 of them developed HCC recurrence. After treatment, LSM increased significantly with a significant reduction in CSCs levels in complete and partial response groups. The median time to observe any recurrence was 14~months. LSM increased significantly post-treatment in patients with recurrence versus no recurrence. Higher levels of CSCs were recorded at baseline and post-treatment in patients with recurrence but without statistical significance. We used univariate analysis to predict the time of recurrence by determining baseline CK-19 and platelet levels as the key factors, while the multivariate analysis determined platelet count as a single factor. The univariate analysis for prediction of overall survival included several factors, LSM and EpCAM (baseline and post-ablation) among them, while multivariate analysis included factors such as Child score B and incomplete ablation.

CONCLUSION: Dynamic changes were observed in LSM and CSCs levels in response to HCC treatment and tumour recurrence. Child score and complete ablation are factors that significantly affect survival.
