Non‐alcoholic fatty liver disease (NAFLD) is the most common liver disease in developed countries, and accumulating evidence suggests it as the hepatic manifestation of the metabolic syndrome (MS). Although the published prevalence of hepatocellular carcinoma (HCC) is low in NAFLD/NASH patients, most of these data have been derived from areas endemic for viral hepatitis. We recruited 162 adults with HCC between February 2007 and March 2008, investigated the underlying etiologies and determined the prevalence of the MS and related features within each group. Patients with NAFLD/NASH‐associated HCC exhibited a higher prevalence of metabolic features (Type 2 diabetes mellitus, hypertension, dyslipidemia, coronary artery disease) compared to non‐NAFLD/NASH‐HCC. Intriguingly, a significant number (41.7%; p < 0.005) of individuals with NAFLD/NASH‐HCC had no evidence of cirrhosis. Patients with alcohol‐induced liver disease also displayed many features (14/19, 73.7%) of the MS, although, in contrast to NAFLD/NASH‐HCC, alcohol‐associated HCC was highly associated with cirrhosis (95.0%; p = 0.064). NAFLD/NASH as the hepatic entity of the MS may itself pose a risk factor for HCC, even in the absence of cirrhosis. The MS may also promote development of HCC among those with alcoholic liver disease. Increased awareness of liver manifestations in the MS may instigate early interventions against developing HCC.

Radioembolization has been demonstrated to allow locoregional therapy of patients with hepatocellular carcinoma not eligible for transarterial chemoembolization or other local therapies. The aim of this study was to validate evidence of the safety and efficacy of this treatment in a European sample of patients with advanced hepatocellular carcinoma (HCC). Therefore, 108 consecutive patients with advanced HCC and liver cirrhosis were included. Yttrium-90 (Y-90) microspheres were administered in a lobar fashion over the right or left branch of the hepatic artery. The response to treatment was evaluated by computed tomography (CT) imaging applying Response Evaluation Criteria in Solid Tumors (RECIST) and World Health Organization (WHO) criteria with recent European Association for the Study of the Liver / National Cancer Institute (EASL/NCI) amendments. Time to progression (TTP) and overall survival were estimated by the Kaplan-Meier method. In all, 159 treatment sessions were performed ranging between one to three treatments per patient. The mean radiation dose per treatment was 120 (618) Gy. According to EASL criteria, complete responses were determined in 3% of patients, partial responses in 37%, stable disease 53%, and primary progression in 6% of patients. TTP was 10.0 months, whereas the median overall survival was 16.4 months. No lung or visceral toxicity was observed. The most frequently observed adverse events was a transient fatigue-syndrome. Conclusion: Radioembolization with Y-90 glass microspheres for patients with advanced HCC is a safe and effective treatment which can be utilized even in patients with compromised liver function. Because TTP and survival appear to be comparable to systemic therapy in selected patients with advanced HCC, randomized controlled trials in combination with systemic therapy are warranted.

Background and Aim: The incidence of hepatocellular carcinoma (HCC) is increasing in western countries. Despite its low sensitivity, the diagnosis of HCC still depends on detection of α-fetoprotein (AFP). Therefore, the aim of this study was to evaluate the combined analysis of AFP and des-γ-carboxy prothrombin (DCP) in a European cohort. Methods: We performed a single-center study (164 HCC/422 controls), in which the serum concentrations of AFP and DCP were determined. Results: AFP and DCP were elevated in HCC patients compared to controls (p < 0.0001). By combination of AFP and DCP, the sensitivity was improved from 28.7% for AFP (cutoff 400 ng/ml; AFP at cutoff 10 ng/ml: 54.9%) to 78.0% using cutoffs of 10 ng/ml for AFP and 5 ng/ml for DCP (DCP alone, cutoff 5 ng/ml: 63.4%). Among early-stage patients, the sensitivity increased from 20% for AFP (cutoff 400 ng/ml; AFP at cutoff 10 ng/ml: 38%) to 55% in combination (DCP alone, cutoff 5 ng/ml: 47%). The area under the curve (AUC) for AFP and DCP was similar (AFP: 0.88; DCP: 0.87; combined: 0.91). Among non-cirrhotic patients, DCP (AUC: 0.93) showed a better performance than AFP (AUC: 0.84). Especially patients with non-alcoholic steatohepatitis had a high percentage of DCP-positive tumors. Conclusion: The data suggest that AFP alone is not sufficient for the serological diagnosis of HCC in European patients, while a combination of AFP and DCP can increase the sensitivity even in early-stage patients.

In intermediate HCC stage patients, both treatments resulted in similar survival probabilities despite more advanced disease in the TARE Y-90 group. Still, TARE Y-90 was better tolerated and associated with less hospitalization and treatment sessions.

Hepatocellular carcinoma (HCC) is one of the leading causes of death in cirrhotic patients worldwide. The detection rate for early stage HCC remains low despite screening programs. Thus, the majority of HCC cases are detected at advanced tumor stages with limited treatment options. To facilitate earlier diagnosis, this study aims to validate the added benefit of the combination of AFP, the novel biomarkers AFP-L3, DCP, and an associated novel diagnostic algorithm called GALAD. Between 2007 and 2008 and from 2010 to 2012, 285 patients newly diagnosed with HCC and 402 control patients suffering from chronic liver disease were enrolled. AFP, AFP-L3, and DCP were measured using the µTASWako i30 automated immunoanalyzer. The diagnostic performance of biomarkers was measured as single parameters and in a logistic regression model. Furthermore, a diagnostic algorithm (GALAD) based on gender, age, and the biomarkers mentioned above was validated. AFP, AFP-L3, and DCP showed comparable sensitivities and specifities for HCC detection. The combination of all biomarkers had the highest sensitivity with decreased specificity. In contrast, utilization of the biomarker-based GALAD score resulted in a superior specificity of 93.3 % and sensitivity of 85.6 %. In the scenario of BCLC 0/A stage HCC, the GALAD algorithm provided the highest overall AUROC with 0.9242, which was superior to any other marker combination. We could demonstrate in our cohort the superior detection of early stage HCC with the combined use of the respective biomarkers and in particular GALAD even in AFP-negative tumors.

Selective internal radiation therapy (SIRT) using 90-yttrium is a local therapy for unresectable liver malignancies. Non-targeted 90-yttrium diversion via a patent hepatic falciform artery (HFA) is seen as risk for periprocedural complications. Therefore, this study aimed to evaluate the impact of a patent HFA on SIRT. 606 patients with SIRT between 2006 and 2012 were evaluated retrospectively. SIRT preparation was performed by digital subtraction angiography including 99mTc-HSAM administration and subsequent SPECT/CT. Patients with an angiographically patent HFA were analyzed for procedural consequences and complications. 19 of 606 patients (3%) with an angiographically patent HFA were identified. Only 11 of these 19 patients received 90-yttrium in the hepatic vessel bed containing the HFA. Initial coil embolization of the HFA succeeded only in three of 11 patients. Out of the eight remaining patients four had no abdominal wall 99mTc-HSAM accumulation. The other four patients presented with an abdominal wall 99mTc-HSAM accumulation, for those a reattempt of HFA embolization was performed or ice packs were administered on the abdominal wall during SIRT. In summary, all patients tolerated SIRT well. A patent HFA should not be considered a SIRT contraindication. In patients with abdominal wall 99mTc-HSAM accumulation HFA embolization or ice pack administration seems to prevent complications.
