Abstract
Recently, metabolic associated steatotic liver disease (MASLD) became the leading cause of chronic liver disease worldwide and one of the most frequent causes of hepatocellular carcinoma (HCC). Nonetheless, in this epidemiological trend, viral hepatitis remains the major driver in hepatic carcinogenesis. Globally, hepatitis B virus (HBV) is the leading cause of hepatocellular carcinoma, with an overall attributable risk of approximately 40%, followed by hepatitis C virus (HCV), which accounts for 28-30% of cases, with significant geographic variations between the Eastern and Western world. Considering all the etiologies, HCC risk increases proportionally with the progression of liver disease, but the risk is consistently higher in patients with viral triggers. This evidence indicates that both direct (due to the oncogenic properties of the viruses) and indirect (through the mechanisms of chronic inflammation that lead to cirrhosis) mechanisms are involved, alongside the presence of co-factors contributing to liver damage (smoking, alcohol, and metabolic factors) that synergistically enhance the oncogenic process. The aim of this review is to analyze the oncogenic role of hepatitis viruses in the liver, evaluating epidemiological changes and direct and indirect viral mechanisms that lead to liver cancer.

Abstract
Antiviral therapy has greatly improved the survival and reduced the incidence of adverse liver events such as hepatic decompensation and hepatocellular carcinoma in chronic hepatitis B patients with cirrhosis (hepatitis B virus [HBV]-cirrhosis). However, hepatitis B surface antigen loss, regarded as the ultimate goal of therapy or functional cure, was rarely achieved during long-term indefinite nucleos(t)ide analogues (Nuc) treatment. Emerging issues such as medication adherence and loss-to-follow-up may lead to increased risk of hepatic decompensation, even catastrophic life-threatening events. Studies have shown that finite therapy is feasible and reasonably safe, even in patients with HBV-cirrhosis. This review critically assesses the scientific evidence of the pros and cons for finite Nuc therapy in HBV-cirrhosis and proposes how to stop Nuc therapy and monitor the off-therapy patients. It also proposes the perspective and unsolved issues to be investigated in the future.

Abstract
Chronic hepatitis B virus (HBV) infection is a major risk factor for the development of hepatocellular carcinoma (HCC), the leading cause of cancer-related death worldwide. Despite progress in the prevention and therapy of HCC, high incidence and recurrence rates of HCC remain big threats, resulting in poor patient survival. Effective biomarkers and targets of HCC are therefore urgently needed for better management and to improve patient outcomes. Pre-S mutants have been well demonstrated as HBV oncoproteins that play important roles in HCC development through activation of multiple oncogenic signal pathways in hepatocytes, in vitro and in vivo. The presence of pre-S mutants in patients with chronic HBV infection and HBV-related HCC has been associated with a significantly higher risk of HCC development and recurrence after curative surgical resection, respectively. In this review, we summarize the roles of pre-S mutants as biomarkers for predicting HBV-related HCC development and recurrence, and highlight the pre-S mutants-activated oncogenic signal pathways as potential targets for preventing HBV-related HCC development.

Abstract
Background Chronic liver disease (CLD) is an important cause of morbidity and mortality and can lead to hepatic fibrosis. This study was conducted to evaluate the diagnostic value of real-time shear wave elastography (SWE) in the assessment of hepatic fibrosis. Methods A systematic search of databases was performed for publications on SWE during the period between 2010 and 2017. The identified studies were analyzed using Meta-disc 1.4 software to integrate and analyze the data. Results Eleven studies comprising 1560 patients were included for analysis. The pooled sensitivity, specificity and diagnostic odds ratio were 0.85 (95% CI: 0.82–0.87), 0.79 (95% CI: 0.76–0.82) and 30.81 (95% CI: 16.55–57.34), respectively for patients with a Metavir-score of ≥ F2; 0.87 (95% CI: 0.84–0.91), 0.84 (95% CI: 0.82–0.87), 41.45 (95% CI:18.25–94.45), respectively for patients with ≥ F3; 0.88(95% CI: 0.83–0.91), 0.91 (95% CI: 0.89–0.92), 67.18 (95% CI:30.02–150.31), respectively for patients with ≥ F4. The areas under the receiver operating characteristic curve of the three groups were 0.9147, 0.9223 and 0.9520, respectively. Conclusions Our work demonstrates that SWE is highly accurate for detecting and staging hepatic fibrosis.

Abstract
Hepatitis B virus (HBV) suppression with nucleot(s)ide analogue therapy reduces the risk of hepatic decompensation and hepatocellular carcinoma (HCC) in patients with advanced liver disease.1 In the present era of potent antiviral therapies, the prognostic significance of the serum HBV DNA level as a biological gradient has substantially diminished; the majority of treated patients achieve virologic suppression.2,3 After control of viremia, a higher baseline fibrosis level is a useful predictor for disease progression.4 Few "prospective" studies on the effects of antiviral agents, especially in chronic hepatitis B (CHB) patients with advanced liver disease, have been reported.

Abstract
Background It is well known that the incidence of developing hepatocelluler carcinoma (HCC) is increased in liver cirrhosis of different etiologies. However, comparison of HCC incidence in various liver diseases has not yet been estimated. We surveyed this comparison. Methods The PubMed database was examined (1989‐2017) for studies published in English language regarding the prospective follow‐up results for the development of HCC in various liver diseases. A meta‐analysis was performed for each liver disease. Results The annual incidence (%) of HCC in the non‐cirrhotic stage and cirrhotic stage, and the ratio of HCC incidence in the cirrhotic stage/non‐cirrhotic stage were as follows. (a) hepatitis B virus liver disease: 0.37%→3.23% (8.73‐fold), (b) hepatitis C virus liver diseases: 0.68%→4.81% (7.07‐fold), (c) primary biliary cholangitis (0.26%→1.79%, 6.88‐fold), (d) autoimmune hepatitis (0.19%→0.53%, 2.79‐fold), and (e) NASH (0.03%→1.35%, 45.00‐fold). Regarding primary hemochromatosis and alcoholic liver diseases, only follow‐up studies in the cirrhotic stage were presented, 1.20% and 2.06%, respectively. Conclusions When the liver diseases advance to cirrhosis, the incidence of HCC is markedly increased. The development of HCC must be closely monitored by ultrasonography, magnetic resonance imaging, and computed tomography, irrespective of the different kinds of liver diseases.

Abstract
BACKGROUND & AIMS The development of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B (CHB) has decreased due to potent antiviral agents. However, it remains uncertain whether the risk of HCC will diminish after long-term antiviral therapy in Asia, where CHB is endemic and vertical transmission is common. This study aimed to compare the incidence of HCC within and beyond the first 5 years of entecavir (ETV) in treatment-naïve Korean patients with CHB. METHODS We performed a retrospective observational analysis of data from 894 consecutive, adult patients with CHB undergoing ETV treatment at a tertiary referral hospital in Ulsan, Korea from January 1, 2007 through April 31, 2017. We compared the HCC incidence rates per 100 person-years within and beyond the first 5 years. Univariate and multivariate analyses for factors predictive of HCC were performed. RESULTS The incidence rate of HCC in patients with CHB did not differ statistically when we compared within and beyond the first 5 years of ETV therapy (2.29% vs 1.66% per person-year, P = 0.217). Failure to achieve maintained virological response (MVR) was a major independent risk factor for HCC in patients at a follow-up of <5 years. In contrast, in patients with a follow-up of ≥5 years, achieving MVR was not significantly associated with HCC development. CONCLUSIONS The incidence rate of HCC may not change significantly before and after 5 years of ETV therapy in Korean CHB patients. The risk of HCC in Asian CHB patients may remain in the long-term.

Abstract
Few studies have directly compared the long-term clinical outcomes of entecavir (ETV) and tenofovir disoproxil fumarate (TDF). This study aimed to compare the risk of mortality, liver transplantation and hepatic complications including hepatocellular carcinoma (HCC) and hepatic decompensation between these drugs in treatment-naïve chronic hepatitis B (CHB). We performed a longitudinal observational analysis of data from 1325 consecutive adult CHB patients with a cumulative adherence of ≥80% to treatment with ETV (n = 721) or TDF (n = 604) at a tertiary referral hospital in Ulsan, Korea, from 1 January 2007 through 31 April 2017. Among the patients, 708 were analysed using propensity score matching with a ratio of 1:1. In the follow-up period of up to 5 years, five patients (0.4%) died, three patients (0.2%) underwent liver transplantation (LT) and 54 patients (4.1%) developed HCC. Hepatic decompensation occurred in 24 (1.8%) patients. ETV therapy did not significantly differ from TDF therapy regarding the risk of liver-related death or LT (HR 0.96; 95% CI, 0.23-4.07; log-rank P = 0.955), HCC (HR, 1.36; 95% CI, 0.72-2.56; log-rank P = 0.340) and hepatic decompensation (HR, 1.64; 95% CI, 0.67-4.00; log-rank P = 0.276). In the 708 propensity-matched pairs, ETV and TDF were also not significantly different with respect to the risk of mortality, LT and hepatic complications. In this longitudinal observational study of 1325 patients with CHB, ETV and TDF therapies were not significantly different regarding the risk of mortality, HCC, LT and hepatic decompensation.

Abstract
The purpose of this study was to determine the validity of previously established ultrasound shear wave elastography (SWE) cut-off values (≥F2 fibrosis) on an independent cohort of patients with chronic liver disease. In this cross-sectional study, approved by the institutional review board and compliant with the Health Insurance Portability and Accountability Act, 338 patients undergoing liver biopsy underwent SWE using an Aixplorer ultrasound machine (SuperSonic Imagine, Aix-en-Provence, France). Median SWE values were calculated from sets of 10 elastograms. A single blinded pathologist evaluated METAVIR fibrosis staging as the gold standard. The study analyzed 277 patients with a mean age of 48 y. On pathologic examination, 212 patients (76.5%) had F0-F1 fibrosis, whereas 65 (23.5%) had ≥F2 fibrosis. Spearman's correlation of fibrosis with SWE was 0.456 (p < 0.001). A cut-off value of 7.29 kPa yielded sensitivity of 95.4% and specificity of 50.5% for the diagnosis of METAVIR stage ≥F2 liver fibrosis in patients with liver disease using the SuperSonic Imagine Aixplorer SWE system.

Abstract
BACKGROUND Sustained abnormal serum alanine aminotransferase (ALT) levels can increase the risk of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B. AIM This study is aimed to confirm the impact of rapid ALT normalization (≤30 IU/L) on HCC risk in patients with hepatitis B virus (HBV)-associated cirrhosis after entecavir (ETV) commencement. METHODS A total of 578 treatment-naïve patients with HBV-associated cirrhosis (mean age 51 ± 9 years, male sex 63.3%) were treated with ETV for more than 1 year. Serum ALT and HBV DNA levels were measured at three time points (baseline, 6, and 12 months after ETV commencement) and subjected to risk factor analysis. RESULTS Median follow-up after ETV commencement was 43 (12-98) months. Cumulative incidences of HCC at 1, 3, 5, and 7 years were 0.3, 8.5, 19.5, and 30.6%, respectively. Univariate Cox regression analysis showed that older age, abnormal ALT at 6 months or 12 months, and lower platelet count were significant risk factors for HCC. However, gender, HBeAg positivity, abnormal ALT levels or HBV DNA levels at baseline, and detectable HBV DNA at 6 or 12 months were not risk factors. Multivariate analysis showed that older age (P < 0.001), abnormal ALT at 12 months (P = 0.006), and lower platelet count (P = 0.034) were the risk factors for HCC. CONCLUSIONS Abnormal serum ALT levels after ETV commencement are significant risk factor for HCC. Therefore, ALT should be rapidly normalized to minimize the risk of HCC development in patients with HBV-associated cirrhosis.

Abstract
BACKGROUND & AIMS In the natural history of hepatitis B virus (HBV) chronic infection, the hepatocellular carcinoma (HCC) risk is unclear. We assessed incidence and predictors of HCC by a systematic review and meta-analysis. METHODS We included longitudinal studies and randomized controlled trials assessing HCC incidence in untreated patients with HBV chronic infection. Incidence rates and their 95% confidence intervals were extracted by each study and pooled together in random effects models. RESULTS Sixty-six studies were included with a total of 347 859 patients. According to liver disease status, the summary incidence rates were in Europe, North America and East Asia, respectively: (a) asymptomatic carriers: 0.07 (95% confidence interval: 0.05-0.09), 0.19 (0.07-0.31) and 0.42 (0.21-0.63) per 100 person-years, respectively; (b) inactive carriers: 0.03 (0.0-0.10), 0.17 (0.02-0.62) and 0.06 (0.02-0.10), respectively; (c) chronic hepatitis: 0.12 (0.0-0.27), 0.48 (0.22-0.91) and 0.49 (0.32-0.66), respectively; (d) compensated cirrhosis (Child-Pugh A): 2.03 (1.30-2.77), 2.89 (1.23-4.55) and 3.37 (2.48-4.26) respectively. Multivariate meta-regression showed a significant increase in incidence rates for age, and for status of a symptomatic carrier, chronic hepatitis and compensated cirrhosis compared to inactive carrier, but not for geographical area after adjusting for age. An increase in the incidence rates was also observed for alcohol intake ≥60 g/dl, HBV genotype C with respect to B and HBV-DNA serum levels >2000 IU/ml, in Asian studies. CONCLUSIONS Hepatocellular carcinoma risk in untreated subjects with HBV chronic infection is strongly related with age and liver disease status.

Abstract
BACKGROUND The present meta-analysis, based on previous studies, was aimed to evaluate the test accuracy of real-time shear wave elastography (SWE) for the staging of liver fibrosis. MATERIAL AND METHODS A systematic search on MEDLINE, PubMed, Embase, and Google Scholar databases was conducted, and data on SWE tests and liver fibrosis staging were collected. For each cut-off stage of fibrosis (F≥2, F≥3, and F≥4), pooled results of sensitivity, specificity, and area under summary receiver operating characteristic (SROC) curve were analyzed. The study heterogeneity was evaluated by χ2 and I2 tests. I2>50% or P≤0.05 indicates there was heterogeneity, and then a random-effects model was applied. Otherwise, the fixed-effects model was used. The publication bias was evaluated using Deeks funnel plots asymmetry test and Fagan plot analysis was performed. RESULTS Finally, 934 patients from 8 published studies were included in the analysis. The pooled sensitivity and specificity of SWE for F≥2 were 85.0% (95% CI, 82-88%) and 81% (95% CI, 71-88%), respectively. The area under the SROC curve with 95% CI was presented as 0.88 (95% CI, 85-91%). The pooled sensitivity and specificity of SWE for F≥3 were 90.0% (95% CI, 83.0-95.0%) and 81.0% (95% CI, 75.0-86.0%), respectively, corresponding to an area of SROC of 0.94 (95% CI, 92-96%). The pooled sensitivity and specificity of SWE for F≥4 were 87.0% (95% CI, 80.0-92.0%) and 88.0% (95% CI, 80.0-93.0%), respectively, corresponding to an area of SROC of 0.92 (95% CI, 89-94%). CONCLUSIONS The overall accuracy of SWE is high and clinically useful for the staging of liver fibrosis. Compared to the results of meta-analyses on other tests, such as RTE, TE, and ARFI, the performance of SWE is nearly identical in accuracy for the evaluation of cirrhosis. For the evaluation of significant liver fibrosis (F≥2), the overall accuracy of SWE seems to be similar to ARFI, but more accurate than RTE and TE.

Abstract
Hepatocellular carcinoma (HCC) is the seventh most common malignancy worldwide. HCC meets all the criteria established by the World Health Organization for performing surveillance on those at-risk for developing cancer. Although there are consensus guidelines in the United States, Europe, and Asia for HCC surveillance, it is unclear if these guidelines are regularly implemented in routine practice to optimize real-life clinical outcomes. We reviewed the current literature on the adherence to current HCC practice guidelines by the American Association for the Study of Liver Diseases (2009), the European Association for the Study of the Liver (2012), and the Asia Pacific Association for the Study of the Liver (2010) for screening/surveillance and outcomes of optimal versus poor adherence. We performed PubMed search for relevant articles regarding HCC surveillance and screening worldwide. Currently, HCC screening is underutilized to a large extent. In most studies, the adherence to HCC screening and surveillance is suboptimal. Various patient, provider, and health care system factors may have all contributed to such nonadherence. Strategies to improve HCC screening and surveillance are urgently needed for early HCC detection and improved survival of HCC patients. Further research is needed to elucidate the various medical and/or cultural knowledge, belief, and practice patterns that can lead to barriers to HCC screening and surveillance at both patient and provider levels. These data will help focus and target advocacy and educational efforts to improve HCC surveillance at all levels: patients, providers, and health care system/government.

Abstract
Alcoholic cirrhosis is generally accepted as a risk factor for hepatocellular carcinoma (HCC) development; however, little research has examined the relationship between nonalcoholic cirrhosis (NAC) and HCC. Thus, the aim of this study was to investigate whether NAC is associated with the risk of HCC and extrahepatic malignancies in Taiwan.We conducted a populated-based retrospective cohort study by using data from the Taiwan National Health Insurance (NHI) program. A total of 2109 patients with NAC were identified from the NHI database between 2000 and 2011. For a control group, 4 patients without NAC were frequency-matched with each NAC patient according to sex, age, and index year. We used Cox proportional hazards regression analysis to calculate adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) and determine the effects of NAC on cancer risk.The overall cancer risk was significantly higher in patients with NAC compared with those without NAC, and this association was consistent among age, sex, and comorbidity groups. The risk of developing HCC was remarkably high in the NAC group compared with in the control cohort (aHR = 122.7, 95% CI = 68.4-220.1); significantly higher risks of extrahepatic malignancies were observed in patients with digestive tract cancers and hematological malignancies. Further analyses stratified according sex, age, and follow-up duration revealed various patterns among the cancer types.The results indicate that patients with NAC in Taiwan have higher risks of HCC, digestive tract cancers, and hematological malignancies.

Abstract
BACKGROUND AND AIM Entecavir is one of the most-used nucleoside analogues for the treatment of patients with chronic hepatitis B virus (HBV) infection. The aim of this study was to clarify the effects of long-term entecavir treatment on the incidence of hepatocellular carcinoma (HCC). METHODS The participants were 249 patients with chronic HBV infection who had been treated by entecavir for more than 2 years. Hepatic functional reserve and incidence of HCC were evaluated, and the factors that might contribute to the development of HCC were analyzed. RESULTS Prothrombin activity was significantly elevated at 60 months after starting entecavir (from 85.9 ± 17.4 to 97.0 ± 16.9%, p < 0.001). The albumin level was also significantly elevated at 60 months after starting entecavir (from 4.0 ± 0.5 to 4.3 ± 0.3 mg/dL, p < 0.001). The annual incidence of HCC decreased over time, and the incidence of HCC was only 1.8% at 5 years after starting entecavir. On multivariate analysis for HCC incidence, older age and low platelet count were significant, independent contributing factors. CONCLUSIONS Long-term treatment with entecavir improved hepatic functional reserve and decreased the incidence of HCC over time after 3 years. To decrease the incidence of HCC, careful induction of long-term entecavir treatment in younger patients with chronic HBV infection and better hepatic functional reserve would be important.

Abstract
PURPOSE To evaluate the accuracy of shear-wave elastography (SWE) for staging liver fibrosis in patients with diffuse liver disease (including patients with hepatitis C virus [HCV]) and to determine the relative accuracy of SWE measurements obtained from different hepatic acquisition sites for staging liver fibrosis. MATERIALS AND METHODS The institutional review board approved this single-institution prospective study, which was performed between January 2010 and March 2013 in 136 consecutive patients who underwent SWE before their scheduled liver biopsy (age range, 18-76 years; mean age, 49 years; 70 men, 66 women). Informed consent was obtained from all patients. SWE measurements were obtained at four sites in the liver. Biopsy specimens were reviewed in a blinded manner by a pathologist using METAVIR criteria. SWE measurements and biopsy results were compared by using the Spearman correlation and receiver operating characteristic (ROC) curve analysis. RESULTS SWE values obtained at the upper right lobe showed the highest correlation with estimation of fibrosis (r = 0.41, P < .001). Inflammation and steatosis did not show any correlation with SWE values except for values from the left lobe, which showed correlation with steatosis (r = 0.24, P = .004). The area under the ROC curve (AUC) in the differentiation of stage F2 fibrosis or greater, stage F3 fibrosis or greater, and stage F4 fibrosis was 0.77 (95% confidence interval [CI]: 0.68, 0.86), 0.82 (95% CI: 0.75, 0.91), and 0.82 (95% CI: 0.70, 0.95), respectively, for all subjects who underwent liver biopsy. The corresponding AUCs for the subset of patients with HCV were 0.80 (95% CI: 0.67, 0.92), 0.82 (95% CI: 0.70, 0.95), and 0.89 (95% CI: 0.73, 1.00). The adjusted AUCs for differentiating stage F2 or greater fibrosis in patients with chronic liver disease and those with HCV were 0.84 and 0.87, respectively. CONCLUSION SWE estimates of liver stiffness obtained from the right upper lobe showed the best correlation with liver fibrosis severity and can potentially be used as a noninvasive test to differentiate intermediate degrees of liver fibrosis in patients with liver disease.

Abstract
BACKGROUND The prognosis of hepatocellular carcinoma (HCC) is unfavorable and needs serum markers that could detect it early to start therapy at a potentially curable phase. OBJECTIVES The aim of this study was to determine the value of serum soluble tumor necrosis factor (TNF) receptor-IIα (sTNFR-IIα) in diagnosis of HCC in patients with chronic hepatitis C virus (HCV) infection. PATIENTS AND METHODS The study was performed on 110 subjects who were classified into five groups. Group I included 20 patients with chronic noncirrhotic HCV infection and persistently normal transaminases for ≥6 months. Group II included 20 patients with chronic noncirrhotic HCV infection and elevated transaminases. Group III included 20 patients with Chronic HCV infection and liver cirrhosis. Group IV included 20 patients with chronic HCV infection with liver cirrhosis and HCC. Group V included 30 healthy age and sex-matched controls. Medical history was taken from all participants and they underwent clinical examination and abdominal ultrasonography. in addition, the following laboratory tests were requested: liver function tests, complete blood count, HBsAg, anti-HCVAb, HCV-RNA by qualitative PCR, and serum levels of α-fetoprotein (AFP) and sTNFR-IIα. RESULTS The serum level of sTNFR-IIα was significantly higher in patients with HCC in comparison to the other groups. A positive correlation was found between the serum levels of sTNFR-IIα and AST and ALT in patients of group-II. Diagnosis of HCC among patients with HCV infection and cirrhosis could be ascertained when sTNFR-IIα is assessed at a cutoff value of ≥ 250 pg/mL. CONCLUSIONS Serum sTNFR-IIα could be used as a potential serum marker in diagnosing HCC among patients with HCV infection.

Abstract
BACKGROUND AND AIMS Chronic hepatitis B (CHB) can progress to cirrhosis, hepatocellular carcinoma (HCC), and ultimately liver-related deaths. Recently, owing to potent antiviral therapy with minimal side-effects, sustained suppression of hepatitis B virus replication can be achieved, thereby preventing such complications. We aimed to reappraise clinical courses regarding disease progression in the era of antiviral therapy. METHODS Between 2001 and 2005, treatment-naïve Korean CHB patients without cirrhosis were enrolled and followed up for at least 5 years. During follow up, antiviral therapy was commenced according to Korean Association for the Study of the Liver guidelines, if eligible, and ultrasonography and laboratory and clinical assessment were performed regularly. Primary end-points were development of cirrhosis, hepatic decompensation, HCC, or liver-related deaths. RESULTS Of 360 patients, 323 (89.7%) received antiviral therapy such as lamivudine (70.6%), entecavir (8.7%), or telbivudine (6.5%). During follow up, cirrhosis developed in 29 (8.1%), hepatic decompensation in 4 (1.1%), and HCC in 15 (4.2%) patients. Annual incidences of cirrhosis, hepatic decompensation, and HCC were 1.05%, 0.14%, and 0.53% per person-year, respectively. Age was an independent predictor for developing cirrhosis (hazard ratio [HR] 1.075, 95% confidence interval [CI] 1.037-1.116; P < 0.001), whereas age (HR 1.060, 95% CI 1.012-1.111; P = 0.014) and cirrhosis (HR 17.470, 95% CI 5.081-60.063; P < 0.001) were those for developing HCC. CONCLUSIONS In the era of antiviral therapy, overall clinical courses have been much improved since introduction of lamivudine in 1999. However, patients with older age or cirrhosis are still subject to HCC development despite appropriate antiviral therapy, necessitating cautious surveillance.

Abstract
Background The incidence of hepatocellular carcinoma (HCC) continues to increase in Japan, but the clinical characteristics of Japanese patients with HCC have not been well described. The aim of this study was to determine the frequencies and utilities of elevated α-fetoprotein (AFP) and des-gamma-carboxy prothrombin (DCP) levels as biomarkers in cryptogenic HCC. Material/Methods A total of 2638 patients with HCC diagnosed between 1999 and 2010 in the Nagasaki Association Study of Liver (NASLD) were recruited for this study. The cause of HCC was categorized into 4 groups; HCC-B, HCC-C, HCC-BC, and HCC-nonBC. The significance of factors was examined for HCC-nonBC using logistic regression analysis in all patients. Results Multivariate analysis identified age, sex, BMI, alcohol consumption, platelet count, AST, ALT, AFP, DCP, and TNM stage as independent and significant risk factors for HCC-nonBC. According to TNM stage, the median AFP levels in HCC-nonBC with TNM stages I, II, and III were significantly lower than in either HCC-B or HCC-C. In TNM stage IV, the median AFP level in HCC-nonBC was significantly lower than in either HCC-B or HCC-BC. The median DCP levels in HCC-nonBC with TNM stages I and II were significantly higher than those in either HCC-B or HCC-C. In TNM stage III, the median DCP level in HCC-nonBC was significantly higher than that in HCC-C. Conclusions DCP was more sensitive than AFP for the diagnosis of early stage cryptogenic HCC. DCP should be used as the main serum test for cryptogenic HCC detection.

Abstract
UNLABELLED Chronic hepatitis B virus (HBV) infection leads to cirrhosis and hepatocellular carcinoma (HCC). Antiviral agents are thought to reduce HCC development, but agents such as lamivudine (LAM) have a high rate of drug resistance. We compared the incidence of HCC in 472 entecavir (ETV)-treated patients and 1,143 nontreated HBV patients (control group). Propensity score matching eliminated the baseline differences, resulting in a sample size of 316 patients per cohort. The drug mutation resistance was 0.8% (4/472) in the ETV group. The cumulative HCC incidence rates at 5 years were 3.7% and 13.7% for the ETV and control groups, respectively (P < 0.001). Cox proportional hazard regression analysis, adjusted for a number of known HCC risk factors, showed that patients in the ETV group were less likely to develop HCC than those in the control group (hazard ratio: 0.37; 95% confidence interval: 0.15-0.91; P = 0.030). Both cohorts were applied in three previously reported risk scales and risk scores were generated based on age, gender, cirrhosis status, levels of alanine aminotransferase, hepatitis B e antigen, baseline HBV DNA, albumin, and bilirubin. The greatest HCC risk reduction occurred in high-risk patients who scored higher on respective risk scales. In sub analyses, we compared treatment effect between nucleos(t)ide analogs, which included matched LAM-treated patients without rescue therapy (n = 182). We found HCC suppression effect greater in ETV-treated (P < 0.001) than nonrescued LAM-treated (P = 0.019) cirrhosis patients when they were compared with the control group. CONCLUSION Long-term ETV treatment may reduce the incidence of HCC in HBV-infected patients. The treatment effect was greater in patients at higher risk of HCC.

Abstract
β-Adrenergic signaling is involved in many processes that may contribute to cancer progression. In this issue of the journal (beginning on page 1007), Nkontchou and colleagues report their retrospective observational finding that the β-blocker propranolol was associated with a highly statistically significant reduction in the incidence of hepatocellular carcinoma in patients with advanced cirrhosis and related esophageal varices. This surprising finding requires confirmation, but the result is biologically plausible. Epidemiologic studies have linked β-blockers with reduced rates of metastasis of other cancers and reduced cancer mortality. Laboratory studies suggest biologic mechanisms for anticancer effects of β-blockers.

Incidence of hepatocellular carcinoma among US patients with cirrhosis of viral or nonviral etiologies. Clin Gastroenterol Hepatol 2012; 10:1412-7. [PMID: 22902757 PMCID: PMC3511850 DOI: 10.1016/j.cgh.2012.08.011] [Citation(s) in RCA: 33] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2012] [Revised: 08/01/2012] [Accepted: 08/06/2012] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS We aimed to identify risk factors for hepatocellular carcinoma (HCC) in patients with cirrhosis in the United States. We performed a prospective study to identify associations between etiologies of cirrhosis and ethnicity with HCC incidence. METHODS We used convenience sampling to select a cohort of 379 patients with cirrhosis who visited the liver clinic at the Stanford University Medical Center from 2001 to 2009 (65% male, 75% white or Hispanic, and 20% Asian). Study end points were HCC diagnosis by histology or noninvasive criteria, liver transplantation, or last screening without HCC. Patients were followed up, with ultrasound or computed tomographic imaging analyses and measurements of serum levels of α-fetoprotein, approximately every 6 months, for a median time of 34 months (range, 6-99 mo). RESULTS The etiologies of cirrhosis in the cohort were 68% hepatitis C, 7% hepatitis B, and 25% nonviral. Forty-four patients (12%) were diagnosed with HCC during the follow-up period. Patients with cirrhosis related to viral hepatitis had a statistically significantly higher incidence of HCC than those with nonviral diseases in Kaplan-Meier analysis (P = .04). There was no statistically significant difference in HCC incidence between Asian and non-Asian patients. In a multivariate Cox proportional hazards model that included age, sex, ethnicity, etiology, and Child-Pugh-Turcotte score, viral cirrhosis was associated significantly with HCC, compared with nonviral cirrhosis (hazard ratio, 3.6; 95% confidence interval, 1.3-10.1; P = .02) but Asian ethnicity was not. CONCLUSIONS In a diverse cohort of patients in the United States with cirrhosis, a viral etiology of cirrhosis was associated with increased incidence of HCC, but Asian ethnicity was not. These findings indicate the importance of cirrhosis etiology in determining risk for HCC.

Abstract
BACKGROUND AND AIMS The National Cancer Screening Program (NCSP) for liver cancer was initiated in 2003 in Korea. The objective of this study was to evaluate the participation rate of the program and to provide preliminary information on its results based on data collected by the NCSP in 2009. METHODS The target population of the NCSP for liver cancer in 2009 was comprised of 373,590 adults aged ≥40 years at high risk for liver cancer. Participation rates and positivity rates were assessed in this population. Multivariate logistic regression analysis was performed to determine the factors associated with participation in the NCSP for liver cancer. RESULTS The overall participation rate was 37.9% and 1,126 participants were positive at screening. The highest participation rates were observed in women, those in their 60s, National Health Insurance beneficiaries, and individuals positive for hepatitis B surface antigen. Positivity rates for men, those in their 70s, Medical Aid Program recipients and individuals with liver cirrhosis were the highest in the respective categories of gender, age, health insurance type, and risk factor for liver cancer. CONCLUSIONS The participation rates of the NCSP for liver cancer are still low, despite the fact that the program targets a high-risk group much smaller than the general population. Efforts to facilitate participation and to reduce disparities in liver cancer screening among Korean men and women are needed. These results provide essential data for evidence-based strategies for liver cancer control in Korea.

Abstract
α-fetoprotein (AFP) is a tumor marker of hepatocellular carcinoma (HCC) and has also been reported to reflect the effectiveness of long-term low-dose interferon (IFN) therapy in hepatitis C virus (HCV)-infected patients with chronic liver disease. The correlation between AFP levels and the incidence of HCC has been discussed over a long period. We investigated whether high levels of AFP at the time of diagnosis were associated with an increased incidence of HCC in patients with HCV. A total of 107 HCV patients with liver cirrhosis without other risks were evaluated for the predictive value of non-invasive risk factors for HCC, including age, gender, alcohol intake, aspartate and alanine aminotransferase levels, bilirubin, albumin, platelet count and AFP levels at study entry, as well as the IFN therapy received. During the follow-up period, HCC developed in 68 (63.6%) patients. Kaplan-Meier estimates were made to assess the cumulative risk of HCC. The 10-year cumulative incidence rate of HCC was 80%. Cox regression analysis was performed on several variables, including age, gender, alcohol consumption, experience of IFN therapy and biochemical parameters. The following factors were identified as exhibiting an increased risk of HCC by univariate analysis: aspartate transaminase (AST) ≥71 IU/l, alanine transaminase (ALT) ≥60 IU/l, AFP ≥6 ng/ml and IFN therapy. Multivariate analysis identified that the AFP level [6–19 ng/ml: hazard ratio (HR), 2.22; P=0.006 and ≥20 ng/ml: HR, 2.09; P=0.003] was an independent and significant risk factor for the development of HCC. A slightly elevated (6–19 ng/ml) AFP level may be a risk factor for HCC in certain cases. By contrast, AFP levels <6 ng/ml indicate a low risk of HCC development in HCV patients with liver cirrhosis.

Abstract
Caffeine is thought to increase the antitumor effect of cisplatin or DNA-damaging agents because it is known that caffeine inhibits DNA repair. Caffeine-assisted chemotherapy has been used in the treatment of osteosarcomas. In addition, there are several reports about combination chemotherapy with caffeine for certain malignancies other than osteosarcomas. However, there are no reports that show the utility of combination chemotherapy with caffeine for hepatocellular carcinoma (HCC). We examined the combined effects of caffeine and cisplatin in human HCC cell lines, and screened for a more effective administration method of caffeine in vitro. Human HCC cell lines (HepG2, HLF, HuH-7, and Li-7) were exposed to caffeine (0-0.5 mM) and cisplatin (0-1.2 μg/mL) for 72 h, either alone or in combination. Cell numbers were measured by WST-8 assay, and cell apoptosis was determined by annexin V-fluorescein isothiocyanate (FITC)/propidium iodide (PI) binding assay. As a result, caffeine increased the antitumor effect of cisplatin on cell proliferation and cell apoptosis in the HCC cell lines. Moreover, this effect was dependent on the amount of exposure to caffeine. These results suggest that caffeine-assisted chemotherapy is useful for HCC treatment.

Abstract
Background Liver stiffness measurement (LSM) using transient elastography (FibroScan®) can assess liver fibrosis noninvasively. This study investigated whether LSM can predict the development of liver-related events (LREs) in chronic hepatitis B (CHB) patients showing histologically advanced liver fibrosis. Methods Between March 2006 and April 2010, 128 CHB patients with who underwent LSM and liver biopsy (LB) before starting nucleot(s)ide analogues and showed histologically advanced fibrosis (≥F3) with a high viral loads [HBV DNA ≥2,000 IU/mL] were enrolled. All patients were followed regularly to detect LRE development, including hepatic decompensation (variceal bleeding, ascites, hepatic encephalopathy, spontaneous bacterial peritonitis, hepatorenal syndrome) and hepatocellular carcinoma (HCC). Results The mean age of the patient (72 men, 56 women) was 52.2 years. During the median follow-up period [median 27.8 (12.6–61.6) months], LREs developed in 19 (14.8%) patients (five with hepatic decompensation, 13 with HCC, one with both). Together with age, multivariate analysis identified LSM as an independent predictor of LRE development [P<0.044; hazard ratio (HR), 1.038; 95% confidence interval (CI), 1.002–1.081]. When the study population was stratified into two groups using the optimal cutoff value (19 kPa), which maximized the sum of sensitivity (61.1%) and specificity (86.2%) from a time-dependent receiver operating characteristic curve, patients with LSM>19 kPa were at significantly greater risk than those with LSM≤19 kPa for LRE development (HR, 7.176; 95% CI, 2.257–22.812; P = 0.001). Conclusion LSM can be a useful predictor of LRE development in CHB patients showing histologically advanced liver fibrosis.

Abstract
Background The incidence of hepatocellular carcinoma (HCC) in Japan has still been increasing. The aim of the present study was to analyze the epidemiological trend of HCC in the western area of Japan, Kyushu. Material/Methods A total of 10,010 patients with HCC diagnosed between 1996 and 2008 in the Liver Cancer study group of Kyushu (LCSK), were recruited for this study. Cohorts of patients with HCC were categorized into five year intervals. The etiology of HCC was categorized to four groups as follows; B: HBsAg positive, HCV-RNA negative, C: HCV-RNA positive, HBsAg negative, B+C: both of HBsAg and HCV-RNA positive, nonBC: both of HBsAg and HCV-RNA negative. Results B was 14.8% (1,485 of 10,010), whereas 68.1% (6,819 of 10,010) had C, and 1.4% (140 of 10,010) had HCC associated with both viruses. The remaining 1,566 patients (15.6%) did not associate with both viruses. Cohorts of patients with HCC were divided into six-year intervals (1996–2001 and 2002–2007). The ratio of C cases decreased from 73.1% in 1996–2001 to 64.9% in 2002–2007. On the other hand, B and -nonBC cases increased significantly from 13.9% and 11.3% in 1996–2001 to 16.2% and 17.6% in 2002–2007, respectively. Conclusions The incidence of hepatocellular carcinoma associated with hepatitis C infection decreased after 2001 in Kyushu area. This change was due to the increase in the number and proportion of the HCC not only nonBC patients but also B patients.

Abstract
AIM The human adenosine diphosphate ribosyl transferase (ADPRT) gene might significantly affect cancer by encoding poly(ADP-ribose) polymerase 1 enzyme (PARP-1) and promoting an important role in cellular responses to DNA damage, genomic stabilization and regulation of tumor suppressor genes. We explored whether polymorphisms of ADPRT affect clearance of hepatitis B virus (HBV) infection or risk of hepatocellular carcinoma (HCC) occurrence in a Korean HBV cohort. METHODS Genotyping was performed in a total of 1066 subjects composed of 434 spontaneously recovered (SR) subjects as normal controls and 632 chronic carriers (CC) of HBV who were further classified into 325 patients with liver cirrhosis (LC)/chronic hepatitis (CH) and 307 patients with HCC. RESULTS Logistic analyses of six common single nucleotide polymorphisms (SNP) and their haplotypes revealed that none of the polymorphisms were significantly associated with clearance of HBV infection and HCC occurrence, except for nominal evidence of association between haplotype 2 (ht2) with HBV clearance (P = 0.05). In the analysis of age of HCC occurrence which is an important factor in disease progression to HCC, results from Cox proportional hazards showed that none of the variants were significantly associated with onset age of HCC occurrence, although a nominal signal in ht4 (P = 0.03, but P(corr) > 0.05) was initially detected. CONCLUSION Although ADPRT is an important gene for cellular responses and tumor regulations, our study provides evidence that ADPRT variations do not affect HBV clearance and HCC occurrence.

Abstract
The purposes of this study were to determine the incidence of hepatocellular carcinoma (HCC) in dual hepatitis B virus (HBV) and hepatitis C virus (HCV) endemic areas and to assess the associated risk factors of HCC development in the community. During April 2004 to November 2005, 4,127 residents of Tainan County, aged 40 years or older, had participated in a comprehensive health examination. Among them, residents with HBV or HCV infection; platelet count less than or equal to 150×10(9)/L; and no hepatic tumor, by liver ultrasonography, were invited to this study. Alpha-fetoprotein (AFP) screening and ultrasonography for HCC surveillance were performed. Once hepatic tumor was detected, the subjects were referred to medical centers for further confirmation and treatment. A total of 1,133 residents were eligible for this study, and 413 (36.5%), including 197 men and 216 women, with a mean age of 64.5 years, were enrolled. There were 21 cases with suspected HCC. Of the 21 cases, 18 (85.7%) accepted further studies and 11 (52.4%) were confirmed to be affected with HCC. All HCCs were unifocal with a diameter less than or equal to 4 cm. In the Kaplan-Meier survival analysis, the 2-year cumulative incidence of HCC was 4.7%. Based on the same analysis with log rank test, AFP greater than or equal to 20 ng/mL (p=0.007), platelet count less than or equal to 100×10(9)/L (p<0.001), and liver cirrhosis (p<0.001) were found to be the associated risk factors of HCC development. In summary, the 2-year cumulative incidence of HCC was 4.7% among adult residents with chronic HBV or HCV infection in this dual HBV and HCV endemic area. Platelet count less than 100×10(9)/L, AFP level greater than 20 ng/mL, and liver cirrhosis were the associated risk factors for HCC development.

Abstract
BACKGROUND & AIMS To assess the risk for the development of hepatocellular carcinoma (HCC) according to the underlying liver status and on-treatment viral response during long-term lamivudine therapy in patients with hepatitis B virus-related liver disease. PATIENTS AND METHODS Between March 1997 and February 2005, a total of 872 patients were treated with lamivudine for more than one year. Between 1983 and 1998, a total of 699 patients were enrolled as historical controls. RESULTS For patients with compensated cirrhosis, HCC occurred in 4.9% (5/103) of cases with sustained viral suppression (persistently <141,500 copies/ml), 11.8% (20/170) in cases with viral breakthrough, and 19.4% (7/36) in cases with a suboptimal response (persistently 141,500 copies/ml): the mean follow-up was 5.1+/-2.7, 5.4+/-2.3, and 3.7+/-1.8 years, respectively. For the control group, HCC developed in 25.0% (37/148) of the cases during a mean follow-up of 6.1+/-4.3 years. Thus, the annual incidence of HCC was 0.95%, 2.18%, 5.26%, and 4.10% in patients with sustained viral suppression, viral breakthrough, suboptimal response, and the control group, respectively. The cumulative incidence of HCC in patients with sustained viral suppression was significantly lower than in patients with a suboptimal response and the controls (p=0.002 and p=0.005, respectively). In patients without cirrhosis and with decompensated cirrhosis, the preventive effects of lamivudine on the development of HCC were not observed (p=0.446 and p=0.123, respectively). CONCLUSION Lamivudine therapy reduced the incidence of HCC in patients with compensated cirrhosis when the viral suppression was sustained.

Abstract
The purpose of this study was to determine the percentage of signal intensity loss (PSIL) threshold for the characterisation of focal liver lesions among patients with chronic liver disease. 55 nodules in 49 patients with chronic liver disease who underwent ferucarbotran-enhanced MR studies were included. Among the 49 patients, 40 had liver cirrhosis and 9 had chronic hepatitis. 8 haemangiomas, 3 focal nodular hyperplasia, 9 dysplastic nodules and 12 well, 19 moderately and 4 poorly differentiated hepatocellular carcinomas (HCCs) were revealed. The PSIL, signal-to-noise ratio and contrast-to-noise ratio of each lesion type were calculated. The diagnostic performance of PSIL on ferucarbotran-enhanced T(2) weighted images (PSIL(T2WI)) and T(2) weighted fat-suppression images (PSIL(FS-T2WI)) that characterised hepatic tumours was compared with receiver operating characteristic (ROC) analysis. Using ROC analysis, the diagnostic performance of PSIL(FS-T2WI) was superior to that of PSIL(T2WI) (p = 0.01). The mean PSIL(FS-T2WI) of the benign lesions was significantly higher than that of HCC (p<0.001), and the mean PSIL(FS-T2WI) of well-differentiated HCC was significantly higher than that of moderately/poorly differentiated HCCs (p = 0.001). With a PSIL(FS-T2WI) threshold of 40% in lesions characterising ferucarbotran-enhanced FS-T2WI, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 88.6%, 95%, 90.9%, 96.9% and 82.6%, respectively. In conclusion, with ferucarbotran-enhanced FS-T2WI, a PSIL(FS-T2WI) threshold of 40% for characterising focal liver nodules among patients with chronic liver disease is recommended. It is useful for distinguishing HCC from benign nodules.

Abstract
BACKGROUND We sought to evaluate the influence of age on the outcome of repeat hepatectomies in patients > or = 75 years with recurrent hepatocellular carcinoma (HCC). METHODS We studied 121 curative repeat hepatectomies retrospectively. Among the 121 patients, 100, 20, and 1 received second, third, and fourth hepatectomies, respectively. The short-term surgical results of a younger group (<75 years; n = 88) and those of an elderly group (> or = 75 years; n = 33) were compared. The long-term prognosis of the patients who underwent second hepatectomies was also compared between a younger group (<75 years; n = 77) and an elderly group (> or = 75 years; n = 23). RESULTS The patients in the elderly group displayed more comorbid conditions pre-operatively, including hypertension and cardiovascular diseases, than the younger group (P < .05); however, there was no significant difference in the incidence of postoperative complications or the duration of postoperative hospital stay. The long-term prognosis in the elderly group was almost identical to that in the younger group. The 3-year overall survival rates for the younger group and the elderly group were 83 vs 73% (P = .51). Disease-free, 3-year survival rates for the younger group and the elderly group were 35% vs 38% (P = .88). CONCLUSION Our findings suggest that advanced age by itself does not have an adverse effect on operative outcomes, including postoperative complications and long-term prognosis. Repeat hepatectomy may, therefore, be justified for recurrent HCC in selected elderly patients.

Abstract
The purpose of this study was to evaluate the diagnostic ability of the expanded gallbladder fossa and right posterior hepatic notch signs for hepatic fibrosis determined by double contrast-enhanced MRI. For patients with chronic viral hepatitis B (n = 96) or hepatitis C (n = 13) who underwent gadopentate dimeglumine-enhanced dynamic MRI followed by ferucarbotran-enhanced gradient-echo imaging, the degree of parenchymal fibrosis was categorised into three groups based on the extent of reticulation and nodularity: (1) pre-cirrhotic or minimal fibrosis; (2) mild to moderate fibrosis; (3) advanced cirrhosis. Each group was evaluated for the presence of a sharp notch in the posterior-medial surface of the right lobe of the liver and expanded gallbladder fossa. The expanded gallbladder fossa sign gradually increased with an increasing degree of fibrosis (Group 1, 50%; Group 2, 61%; Group 3, 78%), and there was no significant difference (p>0.5) between hepatitis B (67%) and C (73%). In the case of the right posterior hepatic notch sign, only 6% of Group 1 and Group 2 patients were positive; 27% of hepatitis B patients and 90% of hepatitis C patients in Group 3 exhibited the sign (p<0.05). Owing to its low prevalence, even in advanced cirrhosis, the right posterior hepatic notch sign is of little value in the diagnosis of cirrhosis due to chronic hepatitis B virus infection, whereas an expanded gallbladder fossa could be used as a non-specific indicator of early fibrosis before the gross appearance of advanced hepatic fibrosis.

Abstract
BACKGROUND AND AIMS Hepatitis B viral markers and liver tests were used as predictors for development of hepatocellular carcinoma and progression to end-stage liver disease in 128 cirrhosis patients with hepatitis B. RESULTS During a median follow-up of 63.5 months, 28 patients (21.9%) developed HCC and 36 (28.1%) died from non-HCC liver deaths. By multivariate analysis, independent predictors of HCC development and their hazard ratios were high alfa-fetoprotein (HR2.83, 95% CI 1.60-5.00, P = 0.0003), negative HBeAg (HR2.33, 95% CI 1.04-5.29, P = 0.04), and low alanine aminotransferase value (HR1.42, 95% CI 1.08-1.89, P = 0.02). Independent predictors of non-HCC liver deaths were HBeAg positivity (HR3.39, 95% CI 1.16-9.93, P = 0.02), decrease albumin (HR1.61, 95% CI 0.99-2.63, P = 0.05), decrease platelet count (HR2.54, 95% CI 1.03-6.25, P = 0.04), high ALT value (HR1.22, 95% CI 1.03-1.43, P = 0.02), and onset of encephalopathy (HR3.34, 95% CI 1.21-9.27, P = 0.02). CONCLUSIONS HBeAg negativity, elevated AFP, and low ALT values predicted HCC development, while HBeAg positivity, abnormal liver tests, and low platelet counts identified patients with non-HCC liver deaths.

Abstract
AIM Skeletal metastases and bone metasitasis are a common occurrence in patients with advanced hepatocellular carcinoma (HCC). Bisphosphonates (BPs), which are used for the treatment of osteoporosis and tumor-associated hypercalcemia, have recently been reported to decrease skeletal morbidity in patients with metastatic bone disease. Several studies revealed that nitrogen-containing BPs (N-BPs) could inhibit tumor growth and migration, indicating the possibility that N-BPs have direct inhibitory effects. We aimed to determine the effects of novel a N-BP (YM529) on human HCC cells in vitro. METHODS HCC cells were treated with various concentrations of YM529 and the growth inhibition rate was determined. Apoptosis was evaluated by caspase-3/7 assay and caspase-9 cleavage detection. The effects of YM529 on the migration of HCC cells induced by hepatocyte growth factor (HGF) were determined by cell migration assay. To evaluate the involvement of the mevalonate pathway, farnesol (FOH) and geranylgeraniol (GGOH) were added. RESULTS YM529 inhibited the proliferation of HCC cells in a dose-dependent manner. The activation of caspase-3/7 and cleavage of caspase-9 demonstrated the involvement of apoptosis in cytotoxicity. GGOH reduced the growth inhibitory effect of YM529 and suppressed the induction of caspase-3/7 activities by YM529 on HCC cells. YM529 inhibited tumor cell migration induced by HGF and this effect was reduced by co-treatment with GGOH. CONCLUSION YM529 inhibited the cell proliferation and migration of HCC cells, implicating the involvement of the mevalonate pathway. These results suggest that N-BPs are potential agents for the treatment of HCC skeletal metastases.

Abstract
BACKGROUND/AIMS Alcohol and the hepatitis B virus (HBV) exert synergistic effects in hepatocelluar carcinogenesis. We aimed to elucidate the clinical significance of the antibody to hepatitis B core antigen (anti-HBc) and occult HBV infection on the development of hepatocellular carcinoma (HCC) in patients with alcoholic liver cirrhosis (LC). METHODS Patients with alcoholic LC alone (n=193) or combined with HCC (n=36), who did not have HBsAg or antibody to hepatitis C virus were enrolled. Clinical data and laboratory data including anti-HBc were investigated at enrollment. The polymerase chain reaction was applied to HBV DNA using sera of patients with HCC or LC after age and sex matching. RESULTS Patients with HCC were older (60+/-11 years vs. 53+/-10 years, mean+/-SD, P<0.001), more likely to be male (100% vs. 89%, P=0.03), and had a higher positive rate of anti-HBc (91.2% vs. 77.3%, P=0.067), and a higher alcohol intake (739+/-448 kg vs. 603+/-409 kg, P=0.076) than those with LC. Age was the only significant risk factor for HCC revealed by multiple logistic regression analysis (odds ratio, 1.056; P=0.003). The positive rate of anti-HBc and alcohol intake did not differ in age- and sex-matched subjects between the LC (n=32) and HCC (n=31) groups. However, the detection rate of serum HBV DNA was higher in the HCC group (48.4%) than in the LC group (0%, P<0.001). CONCLUSIONS Anti-HBc positivity is not a risk factor for HCC. However, occult HBV infection may be a risk factor for HCC in patients with alcoholic LC.

Abstract
Preclinical studies in several animal models as well as clinical trials have shown a reduction in tumor growth following immunotherapy with interleukin-12 (IL-12). This cytokine is appropriate to test in therapeutic clinical trials to treat hepatocarcinoma (HC), a pathology often associated with hepatitis B or C-induced cirrhosis. The local delivery into the liver would be achieved through ex vivo gene transfer using retroviral (rv) vectors in autologous fibroblast carriers. In support of this clinical trial, a rv vector has been constructed to express coordinately both chains p35 and p40 of human IL-12. Here, we have tested good manufacturing practices (GMP) clinical lots of viral vectors derived from the transfected packaging cell line, PG13rvIL-12. We have also devised methods to facilitate the isolation of fibroblasts from freshly harvested skin specimens, enhance their outgrowth in large-scale cultures and assay IL-12 production following transduction, without any selection and irradiation. Twenty-four human skin specimens were processed to obtain fibroblast suspensions that were typically maintained for up to 8 or 12 passages. The mean +/-s.d. overall time for obtaining the required number of transduced cells for the highest IL-12 need was 40 days. The procedure, in accordance with the French medical agency for gene therapy clinical trials, is now ready to begin a clinical trial.

Abstract
This study is to evaluate the associations between adiponectin level and noncardiovascular death and to test a hypothesis that adiponectin level reflects the degree of systemic wasting that precedes death. A nested case-control study was conducted involving 5243 subjects, drawn from 12490 subjects of the Jichi Medical School Cohort Study, whose blood samples had been drawn between 1992 and 1995. Over an average of 10.8 years of follow-up, 103 cases with noncardiovascular death and 565 controls without history/event/death of any cardiovascular disease were identified. Odds ratios (ORs) were estimated relative to the lowest quintile of adiponectin level. The risks for noncardiovascular death of the second lowest quintile and the highest quintile of adiponectin level were significantly higher than that of the lowest quintile when adjusted for age and sex (model 1) (OR, 2.38 [95% confidence interval (CI), 1.12-5.06] and 2.16 [1.01-4.80]). All the statistical significances disappeared when adjusted further for body mass index and C-reactive protein level (model 2). When excluding cases with cancer death, the odds for death in the highest 2 quintiles were significantly higher than those in the lowest quintile in model 1 (OR, 2.80 [95% CI, 1.04-7.59] and 3.74 [1.38-10.18]). The significant difference between the highest vs the lowest quintile remained significant in model 2 and even after adjusting further for smoking, diabetes, and total cholesterol level (model 3) (OR, 3.28 [95% CI, 1.02-10.51] and 3.98 [1.21-13.13]). Adiponectin levels had linear associations with the risks of noncardiovascular noncancer death in models 1, 2, and 3 (OR per 1 SD increase in log-adiponectin, 1.72 [95% CI, 1.23-2.40], 1.89 [1.23-2.91], and 2.01 [1.29-3.15]). Adiponectin is an independent indicator of noncardiovascular mortality that may relate with systemic wasting.

Abstract
It is difficult to achieve a sustained virologic response from antiviral therapy for genotype 1 hepatitis C virus-infected patients without a sufficient virologic response in the early weeks after treatment. However, a recent study has reported on the effectiveness of an extended course of treatment with peginterferon alpha-2a plus ribavirin for slow virologic responders. The aim of this study was to evaluate the economic impact of an extended course of treatment. A Markov cohort model of hepatitis C was designed in order to demonstrate the clinical states, based on the assigned transition probabilities over 30 years. The slow virologic responders treated with an extended 72-week course of therapy could increase by 0.55 the quality-adjusted life years (=15.35-14.80) and reduce the lifetime cost by $2762 (=71 559-69 438) in comparison with those treated by the standard 48-week course. One-way sensitivity analyses did not change the cost-effectiveness. Therefore, the extended 72 weeks of treatment with peginterferon alpha-2a plus ribavirin for slow virologic responders could be cost-effective in comparison with the standard 48 weeks of treatment.

Abstract
Background and aims The role of alphafetoprotein (AFP) in the diagnosis and surveillance of hepatocellular carcinoma (HCC) is getting smaller owing to the advances in imaging modalities. The aims of this study were to assess the diagnostic accuracy of tumor markers in small HCC and to find the optimal cutoff value of each tumor marker for efficient surveillance. Methods Studies in all languages were identified by searching MEDLINE from 1982 to 2002. Studies were included when they showed sensitivity and specificity for HCCs 5 cm or smaller and recruited only patients with chronic hepatitis or liver cirrhosis as control. We assessed diagnostic odds ratios (DORs) for the evaluation of diagnostic accuracy of tumor markers and positive likelihood ratios (LRs+) to find the optimal cutoff value. DORs and LRs+ were combined according to the random effect model. The summary receiver operating characteristics (ROC) curve was also assessed. Results Seventeen articles on three tumor markers-AFP, des-gamma-carboxyprothrombin (DCP), and Lens culinaris agglutinin-reactive fraction of AFP (AFP-L3)-were enrolled after full-text evaluation. AFP was inferior to DCP and AFP-L3 in both DOR (4.50 vs. 8.16 and 10.50) and area under the ROC curve (0.647 vs. 0.688 and 0.695). Optimal cutoff values that provide the best LR+ were 200 ng/ml for AFP, 40 mAU/ml for DCP, and 15% for AFP-L3. Conclusions Diagnostic accuracy of AFP in small HCC was substantially limited. Surveillance including other tumor markers with optimal cutoff value should be conducted to confirm the efficacy of the policy.

Abstract
The natural history of chronic hepatitis B virus (HBV) infection and disease is complex and highly variable. We review the natural history of chronic hepatitis B with emphasis on the rates of disease progression and factors influencing the course of the liver disease. Chronic hepatitis B is characterized by an early replicative phase (HBeAg positive chronic hepatitis) and a late low or non-replication phase with HBeAg seroconversion and liver disease remission (inactive carrier state). Most patients become inactive carriers after spontaneous HBeAg seroconversion with good prognosis, but progression to HBeAg negative chronic hepatitis due to HBV variants not expressing HBeAg occurs at a rate of 1-3 per 100 person years following HBeAg seroconversion. The incidence of cirrhosis appears to be about 2-fold higher in HBeAg negative compared to HBeAg positive chronic hepatitis. In the cirrhotic patient the 5-year cumulative risk of developing hepatocellular carcinoma is 17% in East Asia and 10% in the Western Europe and the United States and the 5-year liver related death rate is 15% in Europe and 14% in East Asia. There is a growing understanding of viral, host and environmental factors influencing disease progression, which ultimately could improve the management of chronic hepatitis B.

Abstract
AIM: To define NGF (nerve growth factor) and its high-affinity receptor trkANGF presence and distribution in fibrotic liver and in HCC, and to verify if NGF might have a role in fibrosis and HCC.
METHODS: Intracellular distribution of NGF and trkANGF were assessed by immunohistochemistry and immuno-electron microscopy in liver specimens from HCC, cirrhosis or both. ELISA was used to measure circulating NGF levels.
RESULTS: NGF and trkANGF were highly expressed in HCC tissue, mainly localized in hepatocytes, endothelial and some Kupffer cells. In the cirrhotic part of the liver they were also markedly expressed in bile ducts epithelial and spindle-shaped cells. Surprisingly, in cirrhotic tissue from patients without HCC, both NGF and trkANGF were negative. NGF serum levels in cirrhotic and/or HCC patient were up to 25-fold higher than in controls.
CONCLUSION: NGF was only detected in liver tissue with HCC present. Intracellular distribution suggests paracrine and autocrine mechanisms of action. Better definition of mechanisms may allow for therapeutic and diagnostic/prognostic use of NGF.

Abstract
OBJECTIVE Recent studies have reported the effectiveness of shorter courses of treatment with peginterferon alpha-2b plus ribavirin for patients with chronic hepatitis C, who achieved a rapid virologic response (RVR), defined as undetectable hepatitis C virus (HCV-) RNA at week 4. The aim of this study was to evaluate the cost-effectiveness of the new protocol for treatment, from the perspective of RVR. METHODS A cost-effectiveness analysis based on the rate of sustained virologic response was performed. A Markov cohort model of hepatitis C was constructed to demonstrate the clinical states on the basis of the assigned transition probabilities over 30 years. The treatment strategies were classified into five subgroups taking into consideration the viral genotypes, viral load, and RVR. The lifetime costs and quality-adjusted life years (QALYs) were compared between the new and standard protocols for treatment. RESULTS Genotype 1-infected patients in the new protocol for treatment compared with the standard one could prolong QALYs by 0.33 and reduce lifetime cost by euro 5993. Genotype 2 or 3-infected patients in the new protocol for treatment compared with the standard one could prolong QALYs by 0.02 and reduce lifetime cost by euro2851. CONCLUSION Treatment strategies that consider viral load and RVR for patients with a low viral load infected with genotype 1 and those infected with genotype 2 or 3 are more cost-effective compared with the standard protocol for treatment.

Abstract
Hepatocellular carcinoma (HCC) is the fifth most common neoplasm, the major cause of death in patients with liver cirrhosis, and the third most common cause of cancer-related death in the world. The geographic distribution of HCC varies significantly and 80% of cases occur in developing countries (Far East and South Asia) where the prevalence of viral hepatitis is higher. The treatment of HCC is difficult because most patients are diagnosed when the tumour is in an advanced stage and is not amenable to potential curative therapy, thus prevention is the key to reducing HCC and its related morbidity and mortality. HCC is unique among cancers, occurring mostly in patients with a known risk factor. Ninety percent of HCCs develop in the context of chronic liver diseases and mainly in patients with cirrhosis. Viral hepatitis is the most common cause of HCC worldwide, followed by alcoholic liver disease (ALD) and other causes such as non-alcoholic fatty liver disease (NAFLD), genetic haemocromatosis (GH) and primary biliary cirrhosis in an advanced stage (III-V). In certain areas of the People’s Republic of China, exposure to aflatoxin and HBV infection are thought to be responsible for the extraordinary high risk of HCC. Substantial progresses in the prevention of virusl-related hepatitis (screening of blood units, use of disposable sanitary tools, HBV vaccination) have been achieved in developed countries, but in the same areas, alcohol- and dysmetabolism-related HCCs are emerging problems which require specific interventions in terms of public health measures. In developing countries, economic constraints limit the development of any program for the prevention of viral hepatitis transmission (including health education campaigns, healthcare politics, primary prevention and the improvement of hygienic and sanitary conditions). When viral liver disease is established, only a minority of patients are treated worldwide and benefit a possible preventive effect of medical treatment on HCC development. Thus the real contribution of medical treatment to HCC prevention in patients with chronic viral hepatitis is small. Great efforts are needed to identify more effective medical measures for primary and secondary prevention of HCC.
