The long‐term changes of liver stiffness (LS) in patients who achieve viral clearance after direct‐acting anti‐HCV therapy remain undefined. We conducted a multicentre prospective study to investigate this aspect. Patients with HCV infection treated with DAAs were enrolled from six Italian centres; they underwent clinical, biochemical, ultrasound and transient elastography evaluations before treatment (T0), 12 weeks (SVR12) and 24 months (T24) after the end of therapy. Among the 516 consecutive patients enrolled, 301 had cirrhosis. LS significantly decreased from T0 to SVR (14.3 vs 11.1 kPa, p =.002), with a progressive reduction until T24 (8.7 kPa, p <.001). However, only patients with steatosis and those who developed HCC did not experience a late improvement in LS. Multivariate analysis of baseline and follow‐up variables identified steatosis as the only independent predictor of failure of LS improvement (OR 1.802, p =.013). ROC curve analysis of the association of LS with the risk of developing HCC showed that SVR12 ≥14.0 kPa had the highest accuracy (sensitivity 82%, specificity 99%; AUC: 0.774). Multivariate analysis revealed that LS was the only variable independently associated with an increased risk of developing HCC (OR 6.470, p =.035). Achieving an SVR was associated with a progressive, long‐term decline of LS, suggesting a late improvement in liver fibrosis, besides the resolution of inflammation. Fatty liver and the development of HCC interfered with late reduction of LS. Patients with an LS ≥14 kPa at 12 weeks after the end of treatment were at higher risk for developing HCC.

Purpose: The aim of this study was to evaluate the relationship between the liver stiffness measurement and the risk of developing hepatocellular carcinoma (HCC) in HCV cirrhotic patients undergoing new direct-acting antivirals. Methods: From April 2015 to April 2017, all consecutive HCV cirrhotic patients treated by direct-acting antivirals were enrolled. A liver stiffness measurement was computed at baseline, and an ultrasound evaluation was provided for all patients at baseline and every 6 months until 1 year after the stopping of the antiviral therapy. The diagnosis of HCC was performed according to international guidelines by imaging technique workup. Results: Two hundred and fifty-eight HCV patients with a diagnosis of cirrhosis were identified. The median liver stiffness was 25.5 kPa. Thirty-five patients developed HCC. Patients were divided into three groups, based on their liver stiffness: < 20 kPa (n = 72), between 20 and 30 kPa (n = 92) and > 30 kPa (n = 94). Compared to the < 20 kPa and 20–30 kPa groups, the > 30 kPa group showed a statistically significant increased risk of HCC (p = 0.019; HR 0.329; 95% CI 0.131–0.830). A ROC curve analysis to assess the overall predictive performance of liver stiffness measurement on the HCC risk was performed. The results allow us to identify a cutoff value of liver stiffness measurement equal to 27.8 kPa, which guarantees the highest sensitivity and specificity (respectively, 72% and 65%). Conclusions: The data underline that the baseline liver stiffness measurement and ultrasound surveillance is a valuable tool for assessing the risk of HCC in cirrhotic patients undergoing the direct-acting antivirals treatment.

The prevalence and independent predictors of the different macroscopic types of hepatocellular carcinoma (HCC) were assessed in 1,073 unselected patients of 14 hospitals in Italy from May 1996 to May 1997. Solitary HCC was the most common cancer type (44.6%), followed by multinodular (44.2%), diffuse (8.4%) and massive (2.8%) types. After adjustment for the influence of confounders by multiple logistic regression analysis, Child-Pugh grades B and C were found to be independent predictors of multinodular (odds ratio, OR, 2.0; 95% confidence interval (CI) = 1.5–2.6) and diffuse (OR 2.6; 95% CI = 1.6–4.4) HCC types. These findings indicate that the majority of HCC cases are not detected at a potentially treatable stage. Delayed detection of HCC is associated with a higher likelihood of the multinodular or diffuse gross pathologic type. [ABSTRACT FROM AUTHOR]

Hepatocellular carcinoma (HCC) is an accepted indication for liver transplantation (LT). Pre-LT adjuvant ablation treatments to prevent tumour progression and drop out from the waiting list have been increasingly adopted at most transplant centers. Trans-catheter arterial chemo-embolization (TACE) is frequently used, but the procedure can be difficult and severe complications may arise. Among them, acute ischemic pancreatitis occasionally occurs and may clinically mimic a post-embolization syndrome. Fatal outcomes of this complication have been reported exceptionally but never in patients awaiting LT. The present case raises concern about the widespread application of TACE and highlights the need for a critical evaluation of the risks and benefits to patients with monofocal small HCC who are scheduled for LT. Superselective embolization of the tumour-feeding artery and systematic monitoring of serum pancreatic enzymes after this radiological procedure are recommended. [Copyright &y& Elsevier]
