Background & Aims: Long‐term outcomes after percutaneous radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) in patients with non‐alcoholic fatty liver disease (NAFLD) have been poorly studied. We aim to determine the outcomes after multibipolar RFA in these patients compared to other aetiologies as well as the prognostic impact of metabolic syndrome (MS). Methods: Patients who underwent multibipolar RFA as the first treatment for HCC within Milan criteria (2008‐2018) were enrolled in this multicentre retrospective cohort from four tertiary centres in France. The association of MS and NAFLD with adverse events and outcomes after percutaneous RFA were assessed using Kaplan Meier method, log‐rank test and uni/multivariate analysis with the Cox models. Results: Among 520 patients, 390 patients (75%) had at least one component of MS including obesity (30%) and 95% had cirrhosis. Sixty‐two patients (12.6%) had NAFLD‐HCC, 225 (45.5%) had alcohol‐related‐HCC, 36 (7.3%) had HBV‐HCC and 171 (34.6%) had HCV‐HCC. Patients with NAFLD‐HCC were significantly older (median age 72.6 years, P <.001), more obese (median BMI 30.3 kg/m2, P <.001) and had more components of MS. Patients with NAFLD‐HCC achieved a median overall survival (OS) of 79 months (1‐year, 3‐year and 5‐year OS of 90%, 71% and 59%). There were no differences in morbidity, tumour recurrence and OS among patients with NAFLD‐HCC vs other aetiologies as well as no prognostic impact of metabolic components. Conclusions: Percutaneous multibipolar RFA is an efficient treatment in HCC patients with NAFLD or metabolic syndrome and achieved similar long‐term oncological outcomes compared to other aetiologies.

Background: We report our experience of the simultaneous occurrence of adenoma and focal nodular hyperplasia (FNH). Liver cell adenoma together with FNH was found in five out of 30 cases of "multiple benign hepatocytic nodules" collected in our files of the Department of Pathology of the University Hospital of Bordeaux, during the last 12 years. All five cases were women on oral contraceptives. In all cases, the reason for surgery was the discovery, by imaging techniques, of an adenoma (4 cases) or of an unidentified benign tumor, possibly an adenoma. Results: Four cases of FNH were discovered by imaging techniques, prior to surgery. Additional small nodules were diagnosed either during surgery or during the slicing of the specimen in 3 cases. Adenoma and the FNH cases identified by imaging techniques were confirmed as such by light microscopy. Some small nodules could not be categorized with certainty because they contained biliary structures without ductular reaction. In one case, the non-nodular liver was abnormal around the area in which there were multiple nodules: there was approximation of portal tracts with portal and hepatic venous thromboses, and portal tract remnants with arteries surrounded with a rim of fibrosis. In two cases, some large hepatic veins had thickened walls. Conclusions: The association of FNH and adenoma could be coincidental or secondary to shared causal mechanisms: a) systemic and local angiogenic abnormalities induced by oral contraceptives; b) tumor-induced growth factors; c) thrombosis and local arterio-venous shunting. A better recognition of the association of adenoma and FNH, particularly in the context of multiple nodules, could be useful in clinical practice. [ABSTRACT FROM AUTHOR]

Background & Aims: The primary aim of this study was to compare the rate of global radiofrequency ablation (RFA) failure between monopolar RFA (MonoRFA) vs. no-touch multi-bipolar RFA (NTmbpRFA) for small hepatocellular carcinoma (HCC) ⩽5cm in cirrhotic patients., Methods: A total of 362 cirrhotic patients were included retrospectively across four French centres (181 per treatment group). Global RFA failure (primary RFA failure or local tumour progression) was analysed using the Kaplan-Meier method after coarsened exact matching. Cox regression models were used to identify factors associated with global RFA failure and overall survival (OS)., Results: Patients were well matched according to tumour size (⩽30/>30mm); tumour number (one/several); tumour location (subcapsular and near large vessel); serum AFP (<10; 10-100; >100ng/ml); Child-Pugh score (A/B) and platelet count (30mm and HCC near large vessel were independent factors associated with global RFA failure. Five-year OS was 37.2% following MonoRFA vs. 46.4% following NTmbpRFA p=0.378., Conclusions: This large multicentre case-matched study showed that NTmbpRFA provided better primary RFA success and sustained local tumour response without increasing severe complications rates, for HCC ⩽5cm., Lay Summary: Using no-touch multi-bipolar radiofrequency ablation for hepatocellular carcinoma ⩽5cm provide a better sustained local tumour control compared to monopolar radiofrequency ablation., (Copyright © 2016 European Association for the Study of the Liver.
