Abstract
Objective We investigated whether there are differences in cancer incidence by geographical area of origin in North-eastern Italy. Methods We selected all incident cases recorded in the Veneto Tumour Registry in the period 2015-2019. Subjects were classified, based on the country of birth, in six geographical areas of origin (Italy, Highly Developed Countries-HDC, Eastern Europe, Asia, Africa, South-central America). Age-standardized incidence rates and incidence rate ratio (IRR) were calculated, for all cancer sites and for colorectal, liver, breast and cervical cancer separately. Results We recorded 159,486 all-site cancer cases; 5.2% cases occurred in subjects born outside Italy, the majority from High Migratory Pressure Countries (HMPC) (74.3%). Incidence rates were significantly lower in subjects born in HMPC in both sexes. Immigrants, in particular born in Asia and Africa, showed lower rates of all site cancer incidence. The lowest IRR for colorectal cancer was observed in males from South-Central America (IRR 0.19, 95%CI 0.09-0.44) and in females from Asia (IRR 0.32, 95%CI 0.18-0.70). The IRR of breast cancer appeared significantly lower than Italian natives in all female populations, except for those coming from HDC. Females from Eastern Europe showed a higher IRR for cervical cancer (IRR 2.02, 95%CI 1.57-2.61). Conclusion Cancer incidence was found lower in subjects born outside Italy, with differences in incidence patterns depending on geographical area of origin and the cancer type in question. Further studies, focused on the country of birth of the immigrant population, would help to identify specific risk factors influencing cancer incidence.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) remains a significant global health burden with a high mortality rate. Over the past 40 years, significant progress has been achieved in the prevention and management of HCC. SUMMARY Hepatitis B vaccination programs, the development of direct acting antiviral drugs for Hepatitis C, and effective surveillance strategies provide a profound basis for the prevention of HCC. Advanced surgery and liver transplantation along with local ablation techniques potentially offer cure for the disease. Also, just recently, the introduction of immunotherapy opened a new chapter in systemic treatment. Finally, the introduction of the BCLC classification system for HCC, clearly defining patient groups and assigning reasonable treatment options, has standardized treatment and become the basis of almost all clinical trials for HCC. With this review, we provide a comprehensive overview of the evolving landscape of HCC management and also touch on current challenges. KEY MESSAGE A comprehensive and multidisciplinary approach is crucial for effective HCC management. Continued research and clinical trials are imperative to further enhance treatment options and will ultimately reduce the global burden of this devastating disease.

[PMID: 38255641 PMCID: PMC10817629 DOI: 10.3390/life14010025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Revised: 11/20/2023] [Accepted: 12/18/2023] [Indexed: 01/24/2024] Open
Abstract
Hepatocellular carcinoma (HCC) is the most frequently found primary malignancy of the liver, showing an accelerated upward trend over the past few years and exhibiting an increasing relationship with metabolic syndrome, obesity, dyslipidemia and type 2 diabetes mellitus. The connection between these risk factors and the occurrence of HCC is represented by the occurrence of non-alcoholic fatty liver disease (NAFLD) which later, based on genetic predisposition and various triggers (including the presence of chronic inflammation and changes in the intestinal microbiome), may evolve into HCC. HCC in many cases is diagnosed at an advanced stage and can be an incidental finding. We present such a scenario in the case of a 41-year-old male patient who had mild obesity and mixed dyslipidemia, no family or personal records of digestive pathologies and who recently developed a history of progressive fatigue, dyspepsia and mild upper abdominal discomfort initially thought to be linked to post-COVID syndrome, as the patient had COVID-19 pneumonia a month prior. The abdominal ultrasound revealed a mild hepatomegaly with bright liver aspect of the right lobe (diffuse steatosis), a large zone of focal steatosis (segments IV, III and II) and a left lobe tumoral mass, highly suggestive of malignancy. Point shear wave elastography at the right lobe ruled out an end-stage chronic liver disease. Additional laboratory investigations, imaging studies (magnetic resonance imaging) and histopathological examination of liver fragments confirmed a highly aggressive HCC, with poorly differentiation-G3, (T4, N 1M 0) and stage IVA, associated with nonalcoholic steatohepatitis (NASH). A sorafenib course of treatment was attempted, but the patient discontinued it due to severe side effects. The subsequent evolution was extremely unfavorable, with rapid degradation, a few episodes of upper digestive bleeding, hepatic insufficiency and mortality in a couple of months. Conclusions: Diagnosis of NASH-related HCC is either an accidental finding or is diagnosed at an advanced stage. In order to earn time for a proper treatment, it becomes important to diagnose it at an early stage, for which regular check-ups should be performed in groups having the risk factors related to it. Patients suffering from obesity and mixed dyslipidemia should undergo periodic abdominal ultrasound examinations. This should be emphasized even more in the cases showing NASH. Complaints of any kind post-COVID-19 should be dealt with keenly as little is yet known about its virulence and its long-term side effects.

Outcomes of liver transplantation for nonalcoholic steatohepatitis-associated hepatocellular carcinoma. HPB (Oxford) 2022; 24:470-477. [PMID: 34544629 DOI: 10.1016/j.hpb.2021.08.943] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Revised: 07/28/2021] [Accepted: 08/21/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND Nonalcoholic steatohepatitis-associated hepatocellular carcinoma (NASH-HCC) is the second-leading cause of liver transplantation (LT) performed for HCC. Despite this, little is known about the clinical characteristics and outcomes of NASH-HCC. METHODS Patients undergoing LT for HCC from 2001 to 2017 at a single center were reviewed. Outcomes of NASH-HCC (n = 51) were compared to other etiologies of HCC including hepatitis C (HCV) hepatitis B (HBV), and alcoholic liver disease (ALD). Outcomes of NASH-HCC were also compared to HCV in the direct-acting antiviral (DAA) era (2014-2017). RESULTS The frequency of NASH-HCC as the primary indication for LT in patients with HCC increased significantly during the study period from 4.4% (2001-2008) to 15.6% in 2017. NASH-HCC patients were significantly older (median age 65 vs. 60; P < 0.001) with significantly lower alpha-fetoprotein levels (7.5 vs. 26.5, P < 0.001) compared to other etiologies. The 1-, 3-, and 5-year overall survival of NASH-HCC was 92%, 86%, and 80%. Overall survival of NASH-HCC was not significantly different compared to HCV, HBV, or ALD. Compared to HCV-HCC in the DAA era (n = 99), NASH-HCC had comparable post-LT survival (3-year survival 87% vs. 86%, P = 0.870). CONCLUSION In this large single-center experience of NASH-HCC, we demonstrate favorable outcomes of NASH-HCC following LT comparable to other common etiologies of HCC.

Abstract
Background and Objectives: Non-alcoholic steatohepatitis (NASH) has become the leading indication for liver transplantation in many countries, with a growing rate in the Western world. NASH patients are older and share a higher risk of comorbidities and cancer than patients with viral and/or alcoholic etiologies. The aims of this study were to evaluate waiting list (WL) registration and liver transplantation rates in patients with NASH-related cirrhosis at Padua University Hospital in the last fifteen years (1.2006-6.2020) and to compare clinical characteristics and indications for liver transplantation between patients with and without NASH, as well as the WL survival and post-transplant outcome. Materials and Methods: All adult patients with cirrhosis listed for liver transplantation at Padua University Hospital between 1.2006 and 6.2020 were retrospectively collected using a prospectively updated database; patients with NASH-related cirrhosis were divided by indication for liver transplantation (Dec-NASH vs. hepatocellular carcinoma (HCC)-NASH) and compared with patients with other etiologies of liver disease. The outcomes in terms of waiting list survival and post-transplant outcome were assessed. Results: One thousand four hundred and ninety-one adult cirrhotic patients were waitlisted during the study period. NASH patients accounted for 12% of all WL registrations, showing an increasing trend over time (from 2.5% in 2006 to 23% in 2020). In the last five years, NASH was the third, but most rapidly growing, indication for liver transplantation at our center. This trend was confirmed both for patients with decompensated cirrhosis (from 1.8% to 18%) and HCC as leading indication for transplantation (from 4% to 30%). NASH patients were older than non-NASH ones (mean ± SD age 59 ± 9 vs. 56 ± 9 years; p < 0.01), whereas no difference was found in gender or Child-Pugh of the model for end-stage liver disease score at WL registration. A majority (60.9%) of NASH patients underwent liver transplantation, showing 1-, 5- and 10-y post-transplant survivals of 86%, 73% and 60%, respectively. Conclusion: NASH cirrhosis has become a rapidly growing indication for liver transplantation at our center, both for HCC and decompensated disease, with good post-transplant survival.

Abstract
Emerging evidence suggests that microRNA dysregulation plays an important role in nonalcoholic steatohepatitis. Using a model of diet-induced liver disease that progresses to fibrosis and hepatocellular carcinoma, we identify a set of 22 microRNA with robust correlation with liver enzyme levels and liver collagen content. These disease-asssociated miRs play pivotal roles in steatosis, extracellular matrix deposition and liver cancer, and may form the basis for identification of therapeutic strategies against this form of liver disease.

Abstract
Non-alcoholic steatohepatitis (NASH) is associated with an increased risk of hepatocellular carcinoma (HCC). Expression levels of hepatic oncogenes, alpha-fetoprotein (afp) and osteopontin (opn)/secreted phosphoprotein 1 (spp1), were investigated using a model of diet-induced NASH. Mice were randomized to a standard diet or a fast-food diet (FFD) for 17 months. Livers from the FFD cohort exhibited hallmark characteristics of NASH with liver fibrosis, with a subset of animals exhibiting HCC. Expression levels of hepatic afp and opn/spp1 were elevated ~2.5 and ~5-fold, respectively, in the FFD cohort. Hepatic opn/spp1 exhibited a direct (r = 0.65) and significant (p < 0.01) correlation with liver hydroxyproline content. Receiver operating characteristic (ROC) curve analysis for hepatic afp, as a diagnostic for HCC, returned an area under (AU) ROC 0.84, a sensitivity of 87.5%, a specificity of 77% and a threshold of >1.05-fold change in mRNA level. The use of hepatic opn/ssp1 as a diagnostic for HCC returned an AUROC 0.88, a sensitivity of 83.3%, a specificity of 86.7% and a threshold of >2.4-fold change in mRNA level. These data point to a transformation of NASH to an oncotype with hepatic oncogene levels as a diagnostic for NASH.

Abstract
BACKGROUND The main etiologies of hepatocellular carcinoma (HCC) were often hepatitis B virus (HBV) or C and alcohol, rarely autoimmune and biliary diseases. Nonalcoholic fatty liver disease (NAFLD) has been an emerging role that could lead to chronic liver disease, nonalcoholic steatohepatitis, cirrhosis, and eventually HCC in recent years. The aim of our study is to investigate and compare the clinical features of HCC in patients with NAFLD and HBV, including age, gender, cirrhosis, liver function tests, largest tumor size, and cancer stage at the time of diagnosis. The survival outcome was compared between the two groups and the significant predictors of mortality were also analyzed in all patients with HCC. METHODS Most patients with HCC were recruited from the database of Cancer Registries in Taipei City Hospital, Ren-Ai Branch, from 2011 to 2017; and the other patients consecutively from the HCC multidisciplinary conference between January 2018 and December 2019. NAFLD was defined as nonviral hepatitis B (negative HBsAg and either positive anti-HBs or negative anti-HBc), nonviral hepatitis C (negative antihepatitis C virus [HCV]), nonalcoholic (alcohol consumption of <30 g/d for men and <20 g/d for women) liver disease, or present or past histological or ultrasonographic evidence of fatty liver. Totally, 23 NAFLD-related and 156 HBV-related HCC patients were enrolled in our study for further analysis. RESULTS NAFLD-related HCC patients were significantly older (median age: 70.0 [61.0-79.0] years vs. 63.0 [56.0-72.0] years, p = 0.012) and heavier (median body mass index [BMI]: 26.6 [24.2-30] kg/m2 vs. 24.8 [22.0-27.1] kg/m2, p = 0.044) than those with HBV-related HCC. They were also more susceptible to diabetes mellitus (DM), and 60.9% (14 of 23) of them had this comorbidity compared with 29.5% (46 of 156) of those with HBV-related HCC (p = 0.003). Only 34.8% (8 of 23) and 71.2% (111 of 156) of patients with NAFLD- and HBV-related HCC were cirrhotic, respectively (p = 0.001). However, gender, tobacco use, international normalized ratio, albumin, creatinine, and cholesterol levels were not significantly different between the two groups. Tumor characteristics such as the Barcelona clinic liver cancer stage, largest tumor size, tumor number, extrahepatic metastasis, and treatment modalities had no significant difference between such groups.According to the Kaplan-Meier method analysis, the overall survival was not significantly different between these two patient groups (log-rank test, p = 0.101). To evaluate which patient group would lead to poor prognosis, we analyzed the survival of all patients through multivariate Cox proportional hazard regression after controlling other factors that may influence the hazard ratio. The analysis revealed that NAFLD and HBV infection as the cause of HCC are not risk factors of poor prognosis. CONCLUSION In conclusion, our study showed NAFLD-related HCC patients were older, heavier, and more had DM than HBV-related. In addition, more NAFLD-related HCC patients were noncirrhotic than HBV-related. The survival rate was similar between NAFLD and HBV-related HCC patients.

Abstract
Left untreated, nonalcoholic fatty liver disease can progress to nonalcoholic steatohepatitis (NASH), fibrosis, and end-stage liver disease. To date, few if any therapies have proven effective against NASH with fibrosis. Quantification and qualification of hepatic scar might enable development of more effective targeted therapies. In a murine model of NASH induced by diet, we characterized fibrillar collagen deposition within the hepatic parenchyma. At harvest, livers from the modified diet cohort exhibited NASH with fibrosis. Transcriptomic analysis of hepatic tissue revealed increased col1a1, col1a2, and col3a1, each of which correlated directly with hepatic hydroxyproline content. Circular polarized microscopic analysis of Picrosirius red-stained liver sections revealed deposition of collagen type I within the parenchyma. Development of therapeutics designed to mitigate collagen type I accumulation might prove effective in NASH with fibrosis.

Abstract
OBJECTIVE Hepatocellular carcinoma (HCC) is the most common cause of primary liver cancer. A major part of diagnostic HCC work-up is based on imaging findings from sonography, computed tomography (CT), or magnetic resonance imaging (MRI) scans. Contrast-enhanced ultrasound (CEUS) allows for the dynamic assessment of the microperfusion pattern of suspicious liver lesions. This study aimed to evaluate the diagnostic value of CEUS compared with CT scans for assessing HCC. METHODS We performed a retrospective, single-center study between 2004 and 2018 on 234 patients with suspicious liver lesions who underwent CEUS and CT examinations. All patients underwent native B-mode, color Doppler and CEUS after providing informed consent. Every CEUS examination was performed and interpreted by a single experienced radiologist (European Federation of Societies for Ultrasound in Medicine and Biology level 3). RESULTS CEUS was performed on all included patients without occurrence of any adverse effects. CEUS showed a sensitivity of 94%, a specificity of 70%, a positive predictive value of 93% and a negative predictive value of 72% for analyzing HCC compared with CT as the diagnostic gold standard. CONCLUSIONS CEUS has an excellent safety profile and shows a high diagnostic accuracy in assessing HCC compared with corresponding results from CT scans.

LI-RADS v2018 major criteria: Do hepatocellular carcinomas in non-alcoholic steatohepatitis differ from those in virus-induced chronic liver disease on MRI? Eur J Radiol 2021; 138:109651. [PMID: 33740627 DOI: 10.1016/j.ejrad.2021.109651] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2021] [Revised: 03/05/2021] [Accepted: 03/09/2021] [Indexed: 02/07/2023]
Abstract
PURPOSE LI-RADS v2018 diagnostic system is used to diagnose hepatocellular carcinoma (HCC) in at risk patients. However, its applicability to HCC in non-alcoholic steatohepatitis (NASH) has not been specifically studied. The purpose of this study was to assess the applicability of LI-RADS v2018 diagnostic system for HCC in patients with NASH. MATERIALS AND METHODS The MRI examinations of 41 patients with HCC and NASH (NASH group) were reviewed and compared to those obtained in 41 patients with HCC and virus-induced chronic liver disease (Virus group). MRI examinations of the two groups were compared for imaging presentation, LI-RADS major criteria and LI-RADS categorization. Qualitative variables were compared using Fisher exact test and quantitative variables using Mann-Whitney U test Interreader agreement was assessed using kappa statistic. RESULTS No significant differences in qualitative and quantitative variables were observed between the two groups. Most common findings in the two groups were hyperenhancement during the arterial phase and visibility on T2-weighted images (93 % vs. 98 %, P = 0.616 and 85 % vs. 88 %, P = 1.000 for NASH group and Virus group, respectively). No differences in prevalence between the two groups were found for any major LI-RADS v2018 criterion. Interreader agreement for LI-RADS categorization was strong for the NASH group (kappa = 0.802) and moderate for the virus group (kappa = 0.720). No differences were found between the two groups for LI-RADS categories (P = 0.303). CONCLUSIONS The LI-RADS v2018 diagnostic algorithm can be applied in patients with NASH.

Abstract
BACKGROUND HCC is the most frequent primary liver cancer entity. Major risk factors comprise chronic HBC and HCV infections, ALD or NAFLD. Apart from the anamnesis, the clinical examination and serologic analysis, an essential part of the diagnostic HCC work-up is due to imaging findings from sonography, CT or MRI scans. HCC lesions feature a distinct vascularization pattern: hyperenhancement during early arterial and hypoenhancement/wash-out during portal venous or delayed phases. CEUS facilitates dynamic assessment of microperfusion patterns of suspicious liver lesions. PURPOSE The purpose of the present retrospective single-center study was to determine the diagnostic value of CEUS for assessing HCC by comparison with findings from MRI scans. MATERIALS AND METHODS Between 2004-2018 292 patients with suspicious liver lesions underwent CEUS and MRI. All patients underwent native B-mode, Color Doppler and CEUS after given informed consent. The applied contrast agent was a second-generation blood pool agent (SonoVue®, Bracco, Milan, Italy). Every CEUS examination was performed and interpreted by a single experienced radiologist (EFSUMB Level 3). RESULTS CEUS was performed on all included patients without occurrence of any adverse effects. CEUS showed a sensitivity of 96%, a specificity of 91%, a PPV of 95% and a NPV of 94% for analyzing HCC in comparison with MRI as the diagnostic gold standard. CONCLUSION With a distinguished safety profile CEUS shows a high diagnostic accuracy in assessing HCC compared to corresponding results from MRI scans.

Abstract
Non-alcoholic fatty liver disease (NAFLD), specifically its progressive form non-alcoholic steatohepatitis (NASH), represents the fastest growing indication for liver transplantation in Western countries. Diabetes mellitus, morbid obesity and cardiovascular disease are frequently present in patients with NAFLD who are candidates for liver transplantation. These factors require specific evaluation, including a detailed pre-surgical risk stratification, in order to improve outcomes after liver transplantation. Moreover, in the post-transplantation setting, the incidence of cardiovascular events and metabolic complications can be amplified by immunosuppressive therapy, which is a well-known driver of metabolic alterations. Indeed, patients with NASH are more prone to developing early post-transplant complications and, in the long-term, de novo malignancy and cardiovascular events, corresponding to higher mortality rates. Therefore, a tailored multidisciplinary approach is required for these patients, both before and after liver transplantation. Appropriate candidate selection, lifestyle modifications and specific assessment in the pre-transplant setting, as well as pharmacological strategies, adjustment of immunosuppression and a healthy lifestyle in the post-transplant setting, play a key role in correct management.

Liver Biopsy Hydroxyproline Content Is a Diagnostic for Hepatocellular Carcinoma in Murine Models of Nonalcoholic Steatohepatitis. Diagnostics (Basel) 2020; 10:diagnostics10100784.

Abstract
There is increasing evidence that nonalcoholic steatohepatitis (NASH) is a risk factor for hepatocellular carcinoma (HCC) in the absence of cirrhosis, a phenomenon termed noncirrhotic HCC. Early diagnosis of HCC is critical to a favorable prognosis. We tested the hypothesis that hydroxyproline content of liver biopsy samples is diagnostic for HCC in murine models of NASH induced by diet or by diet and chemicals. The training set comprised mice fed a standard diet or a fast-food diet with or without administration of thioacetamide. At harvest, livers from the modified diet cohort exhibited NASH with a subset of NASH livers exhibiting HCC. Hydroxyproline content was measured in liver biopsy samples with tissue in the NASH+HCC cohort sampled from the remote, nontumor parenchyma. Plotting the receiver operating characteristics (ROC) with hydroxyproline as the continuous variable against the absence or presence of HCC yielded an area under ROC of 0.87, a threshold of >0.18 μg hydroxyproline/mg liver and sensitivity of 91% with a specificity of 83.3%. The use of liver hydroxyproline content as a diagnostic for HCC in a test set comprising healthy, NASH and NASH+HCC livers proved 87% accurate.

Abstract
Global prevalence of non-alcoholic fatty liver disease (NAFLD) has been growing in the last decades, especially in western countries, due to increased prevalence of diabetes, obesity or other components of metabolic syndrome. NAFLD recently became an important cause of hepatocellular carcinoma (HCC), even in non-cirrhotic patients. Patients with HCC-NAFLD are usually older, with more morbidities (especially cardiovascular diseases and metabolic disorders) and have advanced disease at the diagnosis due to the absence of surveillance, which is considered not cost-effective in patients without advanced fibrosis/cirrhosis, given the large prevalence of NAFLD in the general population. For these reasons, patients with HCC-NAFLD unlikely underwent curative treatments, and have been reported to have lower overall survival (OS) compared to individuals with HCC related to other aetiologies. However, this difference is not confirmed by data of patient subgroups who received curative treatment. In our review, we selected studies published over the past 8 years that analyse characteristics and outcomes of HCC-NAFLD patients who underwent surgery with the aim of identifying features that could predict outcomes and potential selection criteria. All the studies confirm that patients with HCC-NAFLD are older, with many comorbidities and that HCC occurs frequently even in non-cirrhotic livers. There is no agreement about intraoperative and perioperative complications. Regarding outcomes, all papers agree that patients with HCC in NAFLD who undergo surgery have a better OS compared to other aetiologies. Summarizing, surgery is a good curative option for patients with HCC-NAFLD, perhaps even better than transplantation in terms of OS. In this group of patients, it seems to be essential to evaluate cardio-pulmonary and general operative risk, in addition to the normal risk assessment related to liver function to avoid an underestimation, especially for patients without severe underlying fibrosis.

Abstract
Left untreated nonalcoholic fatty liver disease (NAFLD) can progress to nonalcoholic steatohepatitis (NASH), fibrosis, cirrhosis, and hepatocellular carcinoma. The observed failure of clinical trials in NASH may suggest that current model systems do not fully recapitulate human disease, and/or hallmark pathological features of NASH may not be driven by the same pathway in every animal model let alone in each patient. Identification of a model-agnostic disease-associated node can spur the development of effective drugs for the treatment of liver disease. Glycerol-3-phosphate acyltransferase1 (GPAT1) plays a pivotal role in lipid accumulation by shunting fats away from oxidation. In the present study, hepatic GPAT1 expression was evaluated in three etiologically different models of NAFLD. Compared to the sham cohort, hepatic GPAT1 mRNA levels were elevated by ∼5-fold in steatosis and NASH with fibrosis with immunofluorescent staining revealing increased GPAT1 in the fatty liver. A significant and direct correlation (r = 0.88) was observed between hepatic GPAT1 mRNA expression and severity of the liver disease. Picrosirius red staining revealed a logarithmic relation between hepatic GPAT1 mRNA expression and scar. These data suggest that hepatic GPAT1 is an early disease-associated model-agnostic node in NAFLD and form the basis for the development of a potentially successful therapeutic against NASH.

Abstract
Hepatocellular carcinoma (HCC) is the sixth most common cancer in world and third largest cause of cancer-related deaths. The last few decades have witnessed the emergence of non-viral causes of HCC, the most important being non-alcoholic fatty liver disease (NAFLD). NAFLD ranges from simple steatosis in the absence of excessive alcohol intake to non-alcoholic steatohepatitis (NASH) with or without cirrhosis. About 3-15 per cent of the obese patients with NASH progress to cirrhosis and about 4-27 per cent of NASH with cirrhosis patients transform to HCC. It is also known that HCC can develop de novo in patients with NASH without the presence of cirrhosis. Yearly cumulative incidence of NASH-related HCC is low (2.6%) compared to four per cent of viral-HCC. NAFLD has been associated with risk factors such as metabolic syndrome, insulin resistance, altered gut flora and persistent inflammation. Due to alarming rise in metabolic diseases, both in the developing as well as the developed world, it is expected that the incidence of NAFLD/NASH-HCC would rise manifold in future. No definite guidelines have been drawn for surveillance and management of NAFLD/NASH-associated HCC. It is thus important to discuss the entity of HCC in NAFLD at length with special focus on its epidemiology, risk factors, pathophysiology, diagnosis, clinical presentation and prevention.

Abstract
Background/Aims The American Association for the Study of Liver Diseases recommends ultrasound (US) screening for hepatocellular carcinoma (HCC) among cirrhotic patients, regardless of body mass index (BMI), every 6 months. We examined US sensitivity for diagnosis of HCC in obese patients.
Methods Liver transplant patients data with HCC in explant was used (January 2012-December 2017). All patients underwent liver US within 3 months of diagnosis of HCC. Number/size of HCC lesions were extracted from radiologic and pathologic reports. Obesity was defined as BMI ≥30 kg/m2.
Results One hundred sixteen patients were included. 80% were male, with mean BMI of 31 kg/m2. The most common underlying liver disease was hepatitis C virus (62%). At the time of diagnosis, median number of HCC lesions was 2 (interquartile range [IQR], 1–3), and median size of the largest lesion was 2.5 cm (IQR, 1.75–3.9). Overall sensitivity of US study for detection of HCC was 33% (95% confidence interval [CI], 29–48%). Sensitivity was 77% (95% CI, 62–93%) in patients with BMI<30 and 21% (95% CI, 11–30%) in patients with BMI≥30 (P<0.001). Size of the largest HCC lesion (P=0.290) and number of lesions (P=0.505) were not different between groups. Computed tomography (CT) scan detected HCC in 98% of the obese patients with negative US. Conclusions Sensitivity of US for detection of HCC is significantly lower among obese patients compared to overweight and normal weight patients. These patients may benefit from alternating between US and a different imaging modality.

Abstract
To examine the effectiveness of ultrasonography (US) for hepatocellular carcinoma (HCC) surveillance, the prognosis of HCC patients who underwent such screening at an expert medical institution or at general clinics were analyzed, as well as those without US surveillance. From October 2006 to December 2014, 872 patients with naïve HCC were enrolled and divided into the surveillance (S)-group (n=398), who underwent follow-up examinations with US, and the non-S group (n=474). The S-group was further subdivided into patients who underwent follow-up surveillance at Ehime Prefectural Central Hospital, an expert medical institution (SE-group, n=189), and those who received surveillance at general clinics (SG-group, n=209). Prognosis and clinical characteristics were analyzed. In the non-S group, the frequency of patients without viral hepatitis (NBNC-HCC) and Tumor, Node, Metastasis stage was greater. As a result, the median survival time (MST) of the non-S group was reduced, compared with the S group (non-S group, 34.1 vs. S group, 68.2 months; P<0.001). Tumor size was significantly different between the SE- and SG-groups (SE-group, 2.0±1.0 vs. SG-group, 2.5±1.3 cm; P<0.001), whereas tumor number (SE-group: 1.5±1.1 vs. SG-group, 1.7±1.2; P=0.164) and MST (SE-group, 72.1 vs. SG-group, 67.1 months; P=0.931) were not significantly different. Surveillance performed at either an expert medical institution or general clinic improved the prognosis of HCC patients. Dissemination of findings demonstrating the importance of surveillance for HCC to all clinicians as well as patients with chronic liver disease is important, and establishment of an effective surveillance strategy for NBNC-HCC is required.

Abstract
Hepatocellular carcinoma (HCC) represents the second leading cause of cancer deaths worldwide and the main cause of death in patients with cirrhosis. Secondary prevention of HCC can be accomplished through the serial application of screening tests (ultrasound with or without alpha-fetoprotein) to detect the presence of subclinical lesions amenable to potentially curative treatment, such as surgery and ablation. The efficacy of HCC screening is accepted by hepatologists in terms of decline in cancer-specific mortality, but its translation into clinical practice is less than ideal. The effectiveness of HCC screening is hampered by several factors: failure to identify at-risk patients, failure to access care and failure to detect HCC. For each of these steps, possible improvements are discussed in order to face the changing etiology of cirrhosis and expand the screening of at-risk populations by including selected nonalcoholic fatty liver disease patients.

Abstract
Aim: Worldwide, hepatocellular cancer (HCC) is the fourth leading cause of cancer death and occurs 3 times more commonly in males than females. Current surveillance practices do not fully address gender differences in HCC. Methods: Clinical characteristics and survival were compared between males and females using a prospectively collected database of HCC patients. Results: In a cohort of 1206 patients, 307 (25%) were female who presented with older age, more non-alcoholic fatty liver disease/steatohepatitis (NAFLD/NASH), family history of HCC, and hypertension. Males (75%) were more likely to use alcohol and cigarettes. Females were more likely to undergo HCC surveillance, have smaller tumor size at diagnosis, and less vascular involvement. Males who met Milan criteria were more likely to undergo liver transplant than women who met the criteria. Median/mean survival was similar between the genders. Multivariate analysis showed that NAFLD/NASH was predictive of mortality for both males and females, age and smoking were predictive of mortality for males, and transplant was predictive of survival for males. Conclusion: Gender differences in HCC appear related to both behavioral risk factors and biologic factors. Older females with HCC have more NAFLD/NASH and may be overlooked by current surveillance guidelines. These gender disparities may lend support to future studies of gender-based HCC screening.

Supervised learning reveals circulating biomarker levels diagnostic of hepatocellular carcinoma in a clinically relevant model of non-alcoholic steatohepatitis; An OAD to NASH.

Abstract
Although cirrhosis is a key risk factor for the development of hepatocellular carcinoma (HCC), mounting evidence indicates that in a subset of patients presenting with non-alcoholic steatohepatitis (NASH) HCC manifests in the absence of cirrhosis. Given the sheer size of the ongoing non-alcoholic fatty liver disease (NAFLD) epidemic and the dismal prognosis associated with late-stage primary liver cancer there is an urgent need for HCC surveillance in the NASH population. Using serum levels of HCC biomarkers as vectors and biopsy-proven HCC or no HCC as outputs / binary classifier, a supervised learning campaign was undertaken to develop a minimally invasive technique for making a diagnosis of HCC in a clinically relevant model of NASH. Adult mice randomized to control diet or a fast food diet (FFD) were followed for up to 14 mo and serum level of a panel of HCC-relevant biomarkers was compared with liver biopsies at 3 and 14 mo. Both NAFLD Activity Score (NAS) and hepatic hydroxyproline content were elevated at 3 and 14 mo on FFD. Picrosirius red staining of liver sections revealed a filigree pattern of fibrillar collagen deposition with no cirrhosis at 14 mo on FFD. Nevertheless, 46% of animals bore one or more tumors on their livers confirmed as HCC in hematoxylin-eosin-stained liver sections. In this training set, receiver operating characteristic (ROC) curves analysis for serum levels of the HCC biomarkers osteopontin (OPN), alpha-fetoprotein (AFP) and Dickkopf-1 (DKK1) returned concordance-statistic/area under ROC curve of ≥ 0.89. Serum levels of OPN (threshold, 218 ng/mL; sensitivity, 82%; specificity, 86%), AFP (136 ng/mL; 91%; 97%) and DKK1 (2.4 ng/mL; 82%; 81%) diagnostic for HCC were confirmed in a test set comprising mice on control diet or FFD and mice subjected to hepatic ischemia-reperfusion injury. These data suggest that levels of circulating OPN, AFP and DKK1 can be used to make a diagnosis of HCC in a clinically relevant model of NASH.

Abstract
BACKGROUND & AIMS Although hepatitis B virus (HBV) and hepatitis C virus (HCV) infections remain major risk factors for hepatocellular carcinoma (HCC), non-viral causes of HCC, particularly non-alcoholic fatty liver disease (NAFLD), are becoming increasingly prevalent. The aim of this study was to compare the clinical characteristics and survival of cryptogenic and viral HCC. METHODS We conducted a retrospective cohort study involving 3878 consecutive HCC patients seen at two tertiary centres in the United States and one in Taiwan from 2004 to 2014. We compared the clinical characteristics, treatment and survival of patients by underlying aetiology: cryptogenic (n = 696), HBV (n = 1304) or HCV (n = 1878). RESULTS Cirrhosis was present in 66.8% of the cryptogenic HCC patients, compared with 74.7% of HBV-related HCC (HBV-HCC) (P = .001) and 85.9% of HCV-HCC (P < .001). Compared to viral HCC, cryptogenic HCC patients presented with larger tumours and at later stages of disease. Five-year overall survival was 16.3% among cryptogenic HCC patients compared with 31.9% among HBV-HCC patients and 27.7% among HCV-HCC patients (P < .001 for both by the log-rank test). HCC aetiology was not an independent predictor of survival, though ethnicity, cirrhosis status, meeting Milan criteria and treatment allocation were. CONCLUSIONS Compared with viral HCC patients, those with cryptogenic HCC had lower prevalence of cirrhosis, were diagnosed with larger tumours at more advanced stages of disease, and had poorer overall survival. Additional efforts are needed to identify patients at risk of cryptogenic HCC and to identify cryptogenic HCC at earlier stages of disease.

Cholesterol overload in the liver aggravates oxidative stress-mediated DNA damage and accelerates hepatocarcinogenesis. Oncotarget 2017; 8:104136-104148.

Abstract
Primary liver cancers represent the second leading cause of cancer-related deaths worldwide. Diverse etiological factors include chronic viral hepatitis, aflatoxin and alcohol exposure as well as aberrant liver lipid overload. Cholesterol has been identified as a key inducer of metabolic impairment, oxidative stress and promoter of cellular dysfunction. The aim of this work was to address the oxidative stress-mediated DNA damage induced by cholesterol overload, and its role in the development of hepatocellular carcinoma. C57BL/6 male mice were fed with a high cholesterol diet, followed by a single dose of N-diethylnitrosamine (DEN, 10 μg/g, ip). Reactive oxygen species generation, DNA oxidation, antioxidant and DNA repair proteins were analyzed at different time points. Diet-induced cholesterol overload caused enhanced oxidative DNA damage in the liver and was associated with a decrease in key DNA repair genes as early as 7 days. Interestingly, we found a cell survival response, induced by cholesterol, judged by a decrement in Bax to Bcl2 ratio. Importantly, N-acetyl-cysteine supplementation significantly prevented DNA oxidation damage. Furthermore, at 8 months after DEN administration, tumor growth was significantly enhanced in mice under cholesterol diet in comparison to control animals. Together, these results suggest that cholesterol overload exerts an oxidative stress-mediated effects and promotes the development of liver cancer.

Abstract
Metastases in the later stages of hepatocellular carcinoma (HCC) cause the majority of deaths associated with the disease, making early detection crucial to patient survival. Risk models assessing HCC risk in the general population can be used for risk stratification for further HCC surveillance, however, none have been validated externally. Methylation of circulating DNA shows potential for non-invasive diagnosis of HCC. We conducted a prospective case-control study nested within a community-based cohort. We measured methylation levels in six genes (CDKN2A, RASSF1A, STEAP4, TBX2, VIM and ZNF154) which were identified in our previous work, using pre-diagnostic plasma DNA from 237 HCC cases and 257 matched controls. We found TBX2 hypermethylation was associated with increased HCC risk, with ORs (95% CI) of 3.2 (1.8-6.0). The associations were mainly among high-risk subjects; among subjects infected with HBV/HCV, the OR (95% CI) of TBX2 methylation was 5.3 (2.2-12.7). Among subjects with high risk scores, the ORs (95% CIs) were 7.8 (1.5-38.6) for Wen-HCC model ≥16, 5.8 (2.2-15.5) for Hung-HCC ≥15 and 7.5 (2.2-26.0) for Michikawa-HCC ≥8. Adding TBX2 methylation improved the accuracy of risk models for a high-risk population, with the area under the curve (AUC) of 76% for Wen-HCC score with TBX2 methylation compared with 69% with Wen-HCC alone. The AUCs were 63% for Hung-HCC score plus TBX2 methylation, and 53% for Hung-HCC alone, 65% for Michikawa-HCC score plus TBX2 methylation and 58% for Michikawa-HCC alone. Our findings suggest the potential increase in risk assessment discrimination and accuracy from incorporation of DNA methylation.

Abstract
Liver transplantation (LT) is a well-established treatment for hepatocellular carcinoma (HCC) in carefully selected patients. Risk factors for tumors with poor prognostic features on explant have not been well described in a national cohort. We performed a retrospective cohort study of adult LT recipients with HCC transplanted from April 8, 2012 (when explant pathology in United Network for Organ Sharing [UNOS] became available) until September 30, 2014. We evaluated the association between listing diagnosis and other demographic factors with tumor features on explant using logistic regression. High-risk tumor features included the following: > 3 tumors, largest tumor > 5 cm, presence of vascular invasion, presence of metastases, and poor differentiation of tumor. In total, 3733 LT recipients with HCC who had complete explant data in UNOS were included. The median age was 60 years; 78% were male; and 68% were white. Of the primary non-HCC listing diagnoses, 2608 (70%) had hepatitis C virus (HCV); 271 (7%) had nonalcoholic steatohepatitis (NASH); 246 (7%) had alcoholic cirrhosis; and 189 (5%) had hepatitis B virus. Also, 1140 (31%) had evidence of ≥ 1 high-risk explant feature(s). The presence of ≥ 1 high-risk explant feature(s) was associated with HCC recurrence after transplant (odds ratio [OR], 5.00; P < 0.001). Compared with HCV-associated HCC transplant recipients, individuals with NASH had lower likelihood of high-risk explant features (OR, 0.71; P = 0.02) after adjusting for covariables. Women were more likely to have high-risk explant features (OR, 1.23; P = 0.04). Diabetes mellitus (DM) was not associated with high-risk explant features. In conclusion, LT recipients with NASH-associated HCC had fewer high-risk tumor features on explant compared with HCV-associated HCC, despite having higher rates of DM and other potential risk factors for the development of HCC. Women had a higher likelihood of high-risk tumor features. Further study is warranted whether these differences are due to disease-specific or sex-specific influences on tumor biology or due to selection criteria for transplant.

Abstract
AIM To investigate the dynamic alteration of mitochondrial carnitine palmitoyl transferase II (CPT-II) expression during malignant transformation of rat hepatocytes.
METHODS Sprague-Dawley male rats were fed with normal, high fat (HF), and HF containing 2-fluorenylacetamide (2-FAA) diet, respectively. According to the Hematoxylin and Eosin staining of livers, rats were divided into control, fatty liver, degeneration, precancerous, and cancerous groups. Liver lipids were dyed with Oil Red O, CPT-II alterations were analyzed by immunohistochemistry, and compared with CPT-II specific concentration (μg/mg protein). Levels of total cholesterol (Tch), triglyceride (TG), and amino-transferases [alanine aminotransferase (ALT), aspartate aminotransferase (AST)] were determined by the routine methods.
RESULTS After intake of HF and/or HF+2-FAA diets, the rat livers showed mass lipid accumulation. The lipid level in the control group was significantly lower than that in other groups. The changes of serum TG and Tch levels were abnormally increasing, 2-3 times more than those in the controls (P < 0.05). During the rat liver morphological changes from normal to cancer development process with hepatocyte injury, serum AST and ALT levels were significantly higher (4-8 times, P < 0.05) than those in the control group. The specific concentration of CPT-II in liver tissues progressively decreased during hepatocyte malignant transformation, with the lowest CPT-II levels in the cancer group than in any of the other groups (P < 0.05).
CONCLUSION Low CPT-II expression might lead to abnormal hepatic lipid accumulation, which should promote the malignant transformation of hepatocytes.
