Gadoxetic acid improves detection and characterization of focal liver lesions in cirrhotic patients and can estimate liver function in patients undergoing liver resection. The purpose of this article is to describe the optimal gadoxetic acid study protocol for the liver, the unique characteristics of gadoxetic acid, the differences between gadoxetic acid and extra-cellular gadolium chelates, and the differences in phases of enhancement between cirrhotic and normal liver using gadoxetic acid. We also discuss how to obtain and recognize an adequate hepatobiliary phase.

Objectives: The Barcelona Clinic Liver Cancer (BCLC) intermediate stage (BCLC B) includes a heterogeneous population of patients with hepatocellular carcinoma (HCC). Recently, in order to facilitate treatment decisions, a panel of experts proposed to subclassify BCLC B patients. In this study, we aimed to assess the prognostic capability of the BCLC B stage reclassification in a large cohort of patients with untreated HCC managed by the Italian Liver Cancer Group., Methods: We assessed the prognosis of 269 untreated HCC patients observed in the period 1987-2012 who were reclassified according to the proposed subclassification of the BCLC B stage from stage B1 to stage B4. We evaluated and compared the survival of the various substages., Results: Median survival progressively decreased from stage B1 (n=65, 24.2%: 25 months) through stages B2 (n=105, 39.0%: 16 months) and B3 (n=22, 8.2%: 9 months), to stage B4 (n=77, 28.6%: 5 months; P<0.0001). Moreover, we observed a significantly different survival between contiguous stages (B1 vs. B2, P=0.0002; B2 vs. B3, P<0.0001; B3 vs. B4, P=0.0219). In multivariate analysis, the BCLC B subclassification (P<0.0001), MELD score (P=0.0013), and platelet count (P=0.0252) were independent predictors of survival., Conclusions: The subclassification of the intermediate-stage HCC predicts the prognosis of patients with untreated HCC. The prognostic figures identified in this study may be used as a benchmark to assess the efficacy of therapeutic intervention in the various BCLC B substages, whereas it remains to be established whether incorporation of the MELD score might improve the prognosis of treated patients.

Curative treatments, including liver transplantation, surgical resection and percutaneous treatments, are the recommended therapies in BCLC-0 (Barcelona Clinic of Liver Cancer) or BCLC-A hepatocellular carcinoma (HCC). This review provides an overview of some issues of clinical importance concerning curative treatments in HCC.

The lifetime utility of liver transplantation (LT) in patients with hepatocellular carcinoma (HCC) is still controversial. The aim of this study was to ascertain when LT is cost-effective for HCC patients, with a view to proposing new transplant selection criteria. The study involved a real cohort of potentially transplantable Italian HCC patients (n = 2419 selected from the Italian Liver Cancer group database) who received nontransplant therapies. A non-LT survival analysis was conducted, the direct costs of therapies were calculated, and a Markov model was used to compute the cost utility of LT over non-LT therapies in Italian and US cost scenarios. Post-LT survival was calculated using the alpha-fetoprotein (AFP) model on the basis of AFP values and radiological size and number of nodules. The primary endpoint was the net health benefit (NHB), defined as LT survival benefit in quality-adjusted life years minus incremental costs (US $)/willingness to pay. The calculated median cost of non-LT therapies per patient was US $53,042 in Italy and US $62,827 in the United States. On Monte Carlo simulation, the NHB of LT was always positive for AFP model values ≤ 3 and always negative for values > 7 in both countries. A multivariate model showed that nontumor variables (patient's age, Child-Turcotte-Pugh [CTP] class, and alternative therapies) had the potential to shift the AFP model threshold of LT cost-ineffectiveness from 3 to 7. LT proved always cost-effective for HCC patients with AFP model values ≤ 3, whereas the cost-ineffectiveness threshold ranged between 3 and 7 using nontumor variables., (© 2015 American Association for the Study of Liver Diseases.)

Unlabelled: Treatment with sorafenib of patients with advanced hepatocellular carcinoma is challenged by anticipated discontinuation due to tumor progression, liver decompensation, or adverse effects. While postprogression survival is clearly determined by the pattern of tumor progression, understanding the factors that drive prognosis in patients who discontinued sorafenib for any reason may help to improve patient management and second-line trial design. Patients consecutively admitted to three referral centers who were receiving best supportive care following permanent discontinuation of sorafenib for any reason were included. Postsorafenib survival (PSS) was calculated from the last day of treatment to death or last visit available. Two hundred and sixty patients were included in this prospective study, aged 67 years, 60% with hepatitis C, 51% Child-Pugh A, 83% performance status (PS) ≥1, 41% with macroscopic vascular invasion, and 38% with extrahepatic tumor spread. Overall, median PSS was 4.1 (3.3-4.9) months, resulting from 4.6 (3.3-5.7) months for 123 progressors, 7.3 (6.0-10.0) months in 77 with adverse effects, and 1.8 (1.6-2.4) months in 60 decompensated patients (P < 0.001). Postsorafenib survival was independently predicted by PS, prothrombin time, extrahepatic tumor spread, macrovascular invasion, and reason for discontinuation. Two hundred patients potentially eligible for second-line therapy had a PSS of 5.3 (4.6-7.1) months, which was dependent on reasons of discontinuation (P = 0.004), PS (P < 0.001), macrovascular invasion (P < 0.001), and extrahepatic metastases (P < 0.002)., Conclusion: Discontinuation due to adverse effects in the absence of macrovascular invasion, extrahepatic metastases, and deteriorated PS predicts the best PSS in compensated patients, thereby setting the stage for both improved patient counseling and selection for second-line therapy., (© 2015 by the American Association for the Study of Liver Diseases.)

Hepatocellular carcinoma is a challenging malignancy of global importance. It is the sixth most common solid malignancy and the third leading cause of cancer-related death, worldwide. Curative treatments at early stages include liver transplantation, resection and percutaneous ablation, while transarterial chemoembolization can improve survival in patients with intermediate tumor stage. Patients with mild, related symptoms and/or macrovascular invasion or extrahepatic spread are classified under the advanced stage. The standard of care in this group is sorafenib, an inhibitor of Raf kinase and vascular endothelial growth factor receptor, whose effectiveness has been proven by 2 recent randomized controlled trials (RCTs). The aim of this brief review is to highlight the main concerns and pitfalls and to analyze the recent data of literature regarding the efficacy and the management of sorafenib therapy from RCTs to real practice., (© 2015 S. Karger AG, Basel.)

Hepatocellular carcinoma (HCC) is the main cause of death in patients with cirrhosis, with an increasing incidence worldwide. Sorafenib is the choice therapy for advanced HCC. Over time several randomized phase III trials have been performed testing sunitinib, brivanib, linifanib and other molecules in head-to-head comparison with Sorafenib as first-line treatment for advanced-stage HCC, but none of these has so far been registered in this setting. Moreover, another feared vacuum arises from the absence of molecules registered as second-line therapy for patients who have failed Sorafenib, representing an urgent unmet medical need. To date all molecules tested as second-line therapies for advanced hepatocellular carcinoma, failed to demonstrate an increased survival compared to placebo. What are the possible reasons for the failure? What we should expect in the near future?

Background: Data on survival and safety of sorafenib for hepatocellular carcinoma recurrence after liver transplant are still equivocal., Aim: We performed a meta-analysis of published studies, with the aim of estimating the 1-year rates of survival, analysing the variability in survival rates and, finally, identifying the factors associated with a longer survival., Methods: Data from 8 of the 17 selected studies were pooled, while the other 9 were excluded because survival rates were missing. All included studies were retrospective., Results: Overall, the 1-year survival ranged from 18% to 90%. Tumour progression was the main cause of death. The second cause was bleeding, reported only in patients undergoing m-Tor inhibitor therapy. The pooled estimate of 1-year survival was 63%. There was a significant heterogeneity among studies (P < 0.0001). Among the 34 variables assessed by univariate meta-regression, 5 were associated with an increase in the 1-year survival rate: (1) male gender (P = 0.001); (2) Time to progression (P = 0.038); and adverse drug events, divided in (3) gastrointestinal (P = 0.038), (4) cardiovascular (P = 0.029), and (5) dermatological (P = 0.014)., Conclusions: Additional data from multicentre prospective studies are required to clearly determine if sorafenib is a safe and acceptable treatment in hepatocellular carcinoma recurrence after liver transplant. Nevertheless, its association with m-Tor inhibitors should be discouraged., (Copyright © 2015 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd. All rights reserved.)

Background & Aims: The role of hepatic resection for hepatocellular carcinoma (HCC) in different Barcelona Clinic Liver Cancer (BCLC) stages is controversial. We aimed at measuring the survival benefit of resection vs. non-surgical-therapies in each BCLC stage., Methods: Using the ITA.LI.CA database, we identified 2090 BCLC A, B, and C HCC patients observed between 2000 and 2012: 550 underwent resection, 1046 loco-regional therapy (LRT), and 494 best supportive care (BSC). A multivariate log-logistic model was chosen to predict median survival (MS) after resection vs. MS after LRT or BSC. The results were expressed as net survival benefit of resection: (MS resection-MS LRT)/MS BSC., Results: After stratifying for BCLC stage, the median net survival benefit of resection over LRT was: BCLC 0=62% (40%, 82%), A=45% (13%, 65%), B=46% (9%, 76%), C=-16% (-55%, 33%). Model for end-stage liver disease (MELD) score>9, Child B class, and performance status (PST)=2 were the main risk factors for liver resection. 1181 Child A patients (57%) with MELD⩽9 and PST<2 had always a large positive net survival benefit of resection over LRT, independently of BCLC stage: BCLC 0=64% (44%, 85%), A=59% (45%, 74%), B=71% (52%, 90%), C=56% (36%, 78%). Among the 909 (43%) patients with at least one risk factor (MELD>9 or PST=2 or Child B class), resection did not prove any survival benefit over LRT., Conclusions: Resection could result in survival benefit over LRT for HCC patients regardless of their BCLC stage, provided that liver dysfunction (Child B or MELD>9) and PST>1 are absent., (Copyright © 2014 European Association for the Study of the Liver.

Liver transplantation is the only curative alternative for selected patients with hepatocellular carcinoma (HCC) who are not eligible for resection and/or with decompensated cirrhosis. According to Milan criteria the 5-year survival rate is 70-85%, with a recurrence-free survival of 75%. However, HCC recurrence rate after liver transplantation remains a significant problem in the clinical practice. The prognosis in patients with HCC recurrence is poor. The treatment of choice for HCC recurrence is surgery, but it seems that a systemic treatment based on combination of an mTOR inhibitor with sorafenib can be used. Data on safety and efficacy are limited, clinical monitoring is necessary. The aim of this review is to underline the main concerns, pitfalls and warnings for these patients.

Bowel obstruction (BO) is a frequent cause of hospitalization and surgical consultation for acute abdominal pain. It is usually suspected at physical examination, but clinical and laboratory data are often nonspecific. Thus, computed tomography plays a crucial role in a correct diagnosis of BO. Indeed, computed tomography can confirm a diagnosis of BO, and identify the location and cause of the obstruction. In this review, the computed tomography appearances of common and uncommon causes of BO and pseudo-obstruction are reviewed.

Background: We assessed the cost-effectiveness of boceprevir-based triple therapy compared to peginterferon alpha and ribavirin dual therapy in untreated patients with genotype 1 chronic hepatitis C; patients were discriminated according to the combination of baseline plus on-treatment predictors of boceprevir-based triple therapy., Methods: Cost-effectiveness analysis performed according to data from the available published literature. The target population was composed of untreated Caucasian patients, aged 50 years, with genotype 1 chronic hepatitis C, and these were evaluated over a lifetime horizon by Markov model. The study was carried out from the perspective of the Italian National Health Service. Outcomes included discounted costs (in euro, at 2013 value), life-years gained, quality-adjusted life year, and incremental cost-effectiveness ratio. The robustness of the results was evaluated by multivariable probabilistic sensitivity analyses., Results: According to the baseline predictors of sustained virological response (genotype 1b, low viral load, fibrosis F0-F3, and body mass index) and the 1Log drop of HCV-RNA after the dual therapy lead-in period, boceprevir was cost-effective in different patient profiles., Conclusions: In untreated genotype 1b chronic hepatitis C patients, the cost-effectiveness of boceprevir-based triple therapy widely ranges according to different profiles of sustained virological response predictors, allowing optimization and personalization of triple therapy., (Copyright © 2014 Editrice Gastroenterologica Italiana S.r.l.

Background & Aims: In Chronic Hepatitis C (CHC), the influence of steatosis on liver stiffness measurement (LSM) is still debated. We assessed the impact of steatosis and its ultrasonographical sign - bright liver echo pattern (BLEP) - on LSM values and on transient elastography (TE) accuracy for the diagnosis of liver fibrosis, in a cohort of consecutive patients with Genotype 1 (G1) CHC., Methods: Patients (n=618) were assessed by clinical, ultrasonographic and histological (Scheuer score) features. TE was performed using the M probe., Results: Male gender (p=0.04), steatosis as continuous variable (p<0.001), severity of necroinflammation (p=0.02) and stage of fibrosis (p<0.001) were associated with LSM by multivariate linear regression analysis. Among patients within the same fibrosis stages (F0-F2 and F3-F4; F0-F3 and F4), mean LSM values, expressed in kPa, were significantly higher in subjects with moderate-severe steatosis (⩾20% at liver biopsy) compared with those without, as well as in patients with BLEP on US compared with their counterpart. In subjects without severe fibrosis (F0-F2) and without cirrhosis (F0-F3), a higher rate of false-positive LSM results was observed in patients with steatosis ⩾20% compared with those without (F0-F2: 35.3% vs. 17.9%; F0-F3: 38.9% vs. 16.6%), and in patients with BLEP on US (F0-F2: 28.0% vs. 18.3%; F0-F3: 29.7% vs. 17.8%) compared with their counterpart., Conclusions: In patients with G1 CHC, the presence of moderate-severe steatosis, detected by histology or by US, should always be taken into account in order to avoid overestimations of liver fibrosis assessed by TE., (Copyright © 2014 European Association for the Study of the Liver.

Background & Aims: Lead-time is the time by which diagnosis is anticipated by screening/surveillance with respect to the symptomatic detection of a disease. Any screening program, including surveillance for hepatocellular carcinoma (HCC), is subject to lead-time bias. Data regarding lead-time for HCC are lacking. Aims of the present study were to calculate lead-time and to assess its impact on the benefit obtainable from the surveillance of cirrhotic patients., Methods: One-thousand three-hundred and eighty Child-Pugh class A/B patients from the ITA.LI.CA database, in whom HCC was detected during semiannual surveillance (n = 850), annual surveillance (n = 234) or when patients came when symptomatic (n = 296), were selected. Lead-time was estimated by means of appropriate formulas and Monte Carlo simulation, including 1000 patients for each arm., Results: The 5-year overall survival after HCC diagnosis was 32.7% in semiannually surveilled patients, 25.2% in annually surveilled patients, and 12.2% in symptomatic patients (p<0.001). In a 10-year follow-up perspective, the median lead-time calculated for all surveilled patients was 6.5 months (7.2 for semiannual and 4.1 for annual surveillance). Lead-time bias accounted for most of the surveillance benefit until the third year of follow-up after HCC diagnosis. However, even after lead-time adjustment, semiannual surveillance maintained a survival benefit over symptomatic diagnosis (number of patients needed to screen = 13), as did annual surveillance (18 patients)., Conclusions: Lead-time bias is the main determinant of the short-term benefit provided by surveillance for HCC, but this benefit becomes factual in a long-term perspective, confirming the clinical utility of an anticipated diagnosis of HCC., (Copyright © 2014 European Association for the Study of the Liver.

Background: α-Fetoprotein (AFP) is a biomarker commonly used in the management of patients with hepatocellular carcinoma (HCC), although the possible determinants of its serum levels in these patients have not been adequately explored. For this study, the authors evaluated the relevance of demographic, clinical, and oncologic factors to the presence of elevated AFP levels in large cohort of patients with HCC., Methods: In 4123 patients with HCC who were managed by the Italian Liver Cancer Group, AFP levels were assessed along with their association with demographic, biochemical, clinical, and oncologic characteristics. Patients were subdivided according to the presence of elevated AFP (ie, >10 ng/mL)., Results: AFP levels were elevated in 62.4% of patients with HCC. Multivariate logistic regression analysis indicated that being a woman (odds ratio [OR], 1.497; 95% confidence interval [95%CI], 1.250-1.793; P < .0001), the presence of cirrhosis (OR, 1.538; 95% CI, 1.050-2.254; P = .027), liver disease with viral etiology (OR, 1.900; 95% CI, 1.589-2.272; P < .0001), an elevated alanine aminotransferase level (OR, 1.878; 95% CI, 1.602-2.202; P < .0001), a low albumin level (OR, 1.301; 95% CI, 1.110-1.525; P = .012), an HCC tumor size >2 cm (OR, 1.346; 95% CI, 1.135-2.596; P = .001), multinodular HCC (OR, 1.641; 95% CI, 1.403-1.920; P < .0001), and the presence of vascular invasion (OR, 1.774; 95% CI, 1.361-2.311; P < .0001) were associated independently with elevated levels of AFP. Both the median AFP level and the proportion of patients who had elevated levels increased with decreasing degrees of HCC differentiation (P < .0001)., Conclusions: Sex and features of chronic liver disease were identified as nontumor characteristics that influence serum AFP levels in patients with HCC. These findings should be taken into account as limitations in interpreting the oncologic meaning of this biomarker in clinical practice., (© 2014 American Cancer Society.)

Transarterial chemoembolization (TACE) is considered as the standard therapy for patients with intermediate-stage hepatocellular carcinoma. However, given the high heterogeneity of this population, no common strategy or protocol standardization has been defined yet. In the last few years TACE treatment has been combined with sorafenib systemic therapy, reporting overall positive results both in terms of safety and efficacy. This systematic review presents and critically discusses the evidence available on the use of TACE in combination (concomitant or sequential) with sorafenib, focusing also on clinical trials currently ongoing to better define an optimal therapeutic strategy for this group of patients.

Detection and characterization of focal lesions in the cirrhotic liver may pose a diagnostic dilemma. Several benign and malignant lesions may be found in a cirrhotic liver along with hepatocellular carcinoma (HCC), and may exhibit typical or atypical imaging features. In this pictorial essay, we illustrate computed tomography and magnetic resonance imaging findings of lesions such as simple bile duct cysts, hemangioma, focal nodular hyperplasia-like nodules, peribiliary cysts, intrahepatic cholangiocarcinoma, lymphoma, and metastases, all of which occur in cirrhotic livers with varying prevalences. Pseudolesions, such as perfusion anomalies, focal confluent fibrosis, and segmental hyperplasia, will also be discussed. Imaging characterization of non-HCC lesions in cirrhosis is important in formulating an accurate diagnosis and triaging the patient towards the most appropriate management.

Unlabelled: We assessed the cost-effectiveness of sofosbuvir (SOF)-based triple therapy (TT) compared with boceprevir (BOC)- and telaprevir (TVR)-based TT in untreated genotype 1 (G1) chronic hepatitis C (CHC) patients discriminated according to IL28B genotype, severity of liver fibrosis, and G1 subtype. The available published literature provided the data source. The target population was made up of untreated Caucasian patients, aged 50 years, with G1CHC and these were evaluated over a lifetime horizon by Markov model. The study was carried out from the perspective of the Italian National Health Service. Outcomes included discounted costs (in euros at 2013 value), life-years gained (LYG), quality-adjusted life year (QALY), and incremental cost-effectiveness ratio (ICER). Cost of SOF was assumed to be € 3,500 per week, i.e., the price generating a willingness-to-pay threshold of € 25,000 per LYG compared with TVR in the entire population of untreated G1 patients. The robustness of the results was evaluated by one-way deterministic and multivariate probabilistic sensitivity analyses. SOF was cost-effective compared with BOC in all strategies with the exception of cirrhosis and IL28B CC patients. In comparison with TVR-based strategies, SOF was cost-effective in IL28B CT/TT (ICER per LYG € 22,229) and G1a (€ 19,359) patients, not cost-effective in IL28B CC (€45,330), fibrosis F0-F3 (€ 26,444), and in cirrhosis (€ 34,906) patients, and dominated in G1b patients. The models were sensitive to SOF prices and to likelihood of sustained virological response., Conclusion: In untreated G1 CHC patients, SOF-based TT may be a cost-effective alternative to first-generation protease inhibitors depending on pricing. The cost-effectiveness of SOF improved in IL28B CT/TT and G1a patients. SOF was dominated by TVR in G1b patients even if, in clinical practice, this issue could be counterbalanced by the good tolerability profile of SOF and by the shorter treatment duration., (© 2014 by the American Association for the Study of Liver Diseases.)

Background & Aims: Few studies have evaluated the accuracy of ultrasonography in detecting steatosis in patients with chronic hepatitis C. We assessed its accuracy in detecting steatosis and factors that affect its diagnostic performance in consecutive patients with chronic hepatitis C virus genotype 1 infection., Methods: We analyzed data from 515 patients with chronic hepatitis C, confirmed by liver biopsy, assessing anthropometric, biochemical, metabolic, virologic, and ultrasonography features. Transient elastography was performed to measure liver stiffness. Steatosis was identified with ultrasonography based on detection of a bright liver echo pattern., Results: Ultrasonography identified steatosis in 5% or more of parenchyma of the liver with 63.6% sensitivity, 90.4% specificity, an 87.5% positive predictive value (PPV), and a 70.3% negative predictive value (NPV). The higher the degree of steatosis (based on histology analysis), the higher the sensitivity values and NPVs (up to values of 75.3% and 93.8%, respectively, for steatosis in ≥30% of liver), and the lower the specificity values and PPVs (down to values of 69.8% and 31.7% for steatosis in ≥30% of liver, respectively). Body mass index of 30 kg/m(2) or greater (odds ratio, 2.761; 95% confidence interval, 1.156-6.595; P = .02) and liver stiffness measurements of 8.9 kPa or higher (odds ratio, 3.128; 95% confidence interval, 1.715-5.706; P < .001) were independent risk factors for false-negative results from ultrasonography when there was 5% or more steatosis, as well as when there was 10% or more, 20% or more, or 30% or more steatosis., Conclusions: Ultrasonography detects steatosis with low levels of accuracy in patients with chronic hepatitis C virus genotype 1 infection; it has low NPVs for amounts of steatosis of 5% or more and low PPVs for livers with moderate-severe amounts. Higher body mass indexes and liver stiffness measurements are associated with false-negative results in steatosis detection by ultrasonography., (Copyright © 2014 AGA Institute.

Hepatocellular carcinoma (HCC) is a major health problem with a high incidence and mortality all over the world. Natural history of HCC is severe and extremely variable, and prognostic factors influencing outcomes are incompletely defined. Over time, many staging and scoring systems have been proposed for the classification and prognosis of patients with HCC. Currently, the non-ideal predictive performance of existing prognostic systems is secondary to their inherent limitations, as well as to a non-universal reproducibility and transportability of the results in different populations. New serological and histological markers are still under evaluation with promising results, but they require further evaluation and external validation. The aim of this review is to highlight the main tools for assessing the prognosis of HCC and the main concerns, pitfalls and warnings regarding its staging systems currently in use.

Purpose: This study was undertaken to compare response evaluation criteria in solid tumours (RECIST) 1.1 and modified RECIST (mRECIST) in patients with unresectable hepatocellular carcinoma (HCC) on sorafenib, and to describe HCC enhancement changes before and after sorafenib treatment., Methods and Materials: Seventeen patients (12 men, 5 women; mean age 69 years; age range 58-79 years) were included. Tumour response was assessed according to RECIST and mRECIST. Two readers placed a region of interest (ROI) within each target lesion, on the portion showing enhancement during the arterial phase. The lesion attenuation values measured within the ROIs on computed tomography or the signal intensity measured on magnetic resonance imaging, during the unenhanced phase, hepatic arterial phase and venous phase were recorded. Changes in arterial and venous contrast enhancement before and after treatment were compared among the mRECIST groups using Mann-Whitney U test., Results: Agreement between mRECIST and RECIST was good (Cohen's k coefficient, 0.791). Patients with partial response had a greater decrease in arterial enhancement (-79.8%) than did patients with stable disease (SD) (-24.8%; p = 0.011) or progressive disease (PD) (-32.9%; p = 0.034). No statistically significant difference in arterial enhancement variation was found among patients with SD and PD. No statistically significant difference in venous enhancement was found among the mRECIST groups., Conclusions: mRECIST showed a more favourable response compared to RECIST 1.1 in patients with unresectable HCC receiving sorafenib.

Cancer is a prevalent disease in the elderly population and hepatocellular carcinoma (HCC) is a major health problem among all tumors. Curative treatments for early-stage include liver transplantation, resection and percutaneous ablation. Transarterial chemoembolization (TACE) and sorafenib, classified as non-curative treatments, can improve survival for patients with intermediate and advanced tumors, respectively. Even if the incidence of HCC progressively increases with advanced age in all populations, reaching a peak at 70 years, few reports concerning correct management of HCC in elderly patients exist. Moreover, data from large randomized controlled trials (RCT) poorly reflect the elderly population that is often quantitatively and qualitatively underrepresented, as a result of the presence of tight enrolment criteria. The aim of this brief review is to highlight the main concerns, pitfalls and warnings regarding the management of HCC in elderly patients, with particular focus on systemic therapy with sorafenib.

Background & Aims: Randomised controlled trials (RCTs) show that triple therapy (TT) with peginterferon alfa, ribavirin, and boceprevir (BOC) or telaprevir (TVR) is more effective than peginterferon-ribavirin dual therapy (DT) in the treatment of genotype 1 (G1) chronic hepatitis C (CHC) patients with previous relapse (RR), partial response (PAR), and null-response (NR). We assess the cost-effectiveness of TT compared to no therapy in the treatment of patients previously treated with G1 CHC., Methods: The available published literature provided the data source. The target population was made up of previously treated Caucasian patients with G1 CHC and these were evaluated over a lifetime horizon by Markov model. The study was carried out from the perspective of the Italian National Health Service. Outcomes included discounted costs (in euro at 2012 value), life years gained (LYG), quality adjusted life year (QALY), and incremental cost-effectiveness ratio (ICER).The robustness of the results was evaluated by one-way deterministic and multivariable probabilistic sensitivity analyses., Results: In RR patients, ICER per LYG compared to no therapy was €9555 for BOC-LEAD-IN-RR and €7910 for TVR-LEAD-IN-RR, being BOC dominated by TVR. In PAR patients, ICER for LYG was €11,947 for BOC-LEAD-IN-PAR and €14,931 for TVR-PAR, being TVR cost-effective compared to BOC (ICER for QALY €22,258). In NR patients, ICER for LYG was €26,499 for TVR-LEAD-IN-NR. The models were sensitive to likelihood of sustained virological response and to BOC/TVR prices., Conclusions: 1st generation HCV PI is highly cost-effective compared to no therapy in RR and PAR G1 CHC patients. TVR dominated BOC in RR, and was cost-effective compared to BOC in PAR patients. In NR patients an assessment of the response after a lead-in period should be performed to improve safety and cost-effectiveness., (Copyright © 2013 European Association for the Study of the Liver.

Background & Aims: Hepatitis C virus (HCV) is the leading aetiological factor of HCC in the western world where, overall, its incidence is increasing, despite data suggesting an initial drop in some areas. The aim of this study was to evaluate epidemiology, clinical features and survival of HCV-related HCC (HCV-HCC) in a wide time range in Italy., Methods: Multicentre retrospective study including 3695 patients prospectively recruited by the ITA.LI.CA group. Patients were classified into three subgroups according to aetiology (Group A[GA], pure HCV; Group B[GB], HCV + cofactors; and Group C[GC], non-HCV) and in 5 time cohorts (5 years each), according to the year of diagnosis. Age, gender, Child-Pugh score, modality of diagnosis, stage, presence of thrombosis/metastases, type of treatment and survival were analysed., Results: A total of 1801 GA patients, 445 GB and 1333 GC were recruited. The number of GA patients peaked in the 1996-2000, gradually dropping thereafter (P < 0.0001), as observed for GB (P < 0.0001). Age at diagnosis increased (P < 0.0001), while percentage of patients diagnosed during surveillance and stage improved only in GA (P = 0.02 and P = 0.003 respectively). The survival significantly increased over time particularly in GA (median 37 months) and was longer in GA than in GB and GC (P < 0.0001)., Conclusions: The prevalence of HCC-HCV is decreasing in Italy since 2001. HCV-HCC patients are older, more frequently diagnosed under surveillance and in an earlier stage. HCC survival improved in the last 15 years and is significantly higher in patients with HCV-HCC. We therefore expect a further drop in both incidence and mortality for HCV-HCC in the years to come., (© 2013 John Wiley & Sons A/S.)

Surgical resection and imaging guided treatments play a crucial role in the management of hepatocellular carcinoma (HCC). Although the primary end point of treatment of HCC is survival, radiological response could be a surrogate end point of survival, and has a key role in HCC decision-making process. However, radiological assessment of HCC treatment efficacy is often controversial. There are few doubts on the evaluation of surgical resection; in fact, all known tumor sites should be removed. However, an unenhancing partial linear peripheral halo, in most cases, surrounding a fluid collection reducing in size during follow-up is demonstrated in successfully resected tumor with bipolar radiofrequency electrosurgical device. Efficacy assessment of locoregional therapies is more controversial and differs between percutaneous ablation (e.g., radiofrequency ablation and percutaneous ethanol injection) and transarterial treatments (e.g., conventional transarterial chemoembolization, transarterial chemoembolization with drug eluting beads and radioembolization). Finally, a different approach should be used for new systemic agent that, though not reducing tumor mass, could have a benefit on survival by delaying tumor progression and death. The purpose of this brief article is to review HCC imaging appearance after treatment.

Background and Aims: Plasma levels of NT-pro-BNP, a natriuretic peptide precursor, are raised in the presence of fluid retention of cardiac origin and can be used as markers of cardiac dysfunction. Recent studies showed high levels of NT pro BNP in patients with cirrhosis. We assessed NT pro-BNP and other parameters of cardiac dysfunction in patients with cirrhosis, with or without ascites, in order to determine whether the behaviour of NT pro BNP is linked to the stage of liver disease or to secondary cardiac dysfunction., Methods: Fifty eight consecutive hospitalized patients mostly with viral or NAFLD-related cirrhosis were studied. All underwent abdominal ultrasound and upper GI endoscopy. Cardiac morpho-functional changes were evaluated by echocardiography and NT-pro-BNP plasma levels determined upon admission. Twenty-eight hypertensive patients, without evidence of liver disease served as controls., Results: Fifty eight cirrhotic patients (72% men) with a median age of 62 years (11% with mild arterial hypertension and 31% with type 2 diabetes) had a normal renal function (mean creatinine 0.9 mg/dl, range 0.7-1.06). As compared to controls, cirrhotic patients had higher NT pro-BNP plasma levels (365.2±365.2 vs 70.8±70.6 pg/ml; p<0.001). Left atrial volume (LAV) (61.8±26.3 vs 43.5±14.1 ml; p = 0.001), and left ventricular ejection fraction (62.7±6.9 vs. 65.5±4%,; p = 0.05) were also altered in cirrhotic patients that in controls. Patients with F2-F3 oesophageal varices as compared to F0/F1, showed higher e' velocity (0.91±0.23 vs 0.66±0.19 m/s, p<0.001), and accordingly a higher E/A ratio (1.21±0.46 vs 0.89±0.33 m/s., p = 0.006)., Conclusion: NT-pro-BNP plasma levels are increased proportionally to the stage of chronic liver disease. Advanced cirrhosis and high NT-pro-BNP levels are significantly associated to increased LAV and to signs of cardiac diastolic dysfunction. NT pro-BNP levels could hence be an useful prognostic indicators of early decompensation of cirrhosis.

Background: Radio-frequency ablation (RFA) has been employed in the treatment of Barcelona Clinic Liver Cancer (BCLC) early stage hepatocellular carcinoma (HCC) as curative treatments., Aim: To assess the effectiveness and the safety of RFA in patients with early HCC and compensated cirrhosis., Methods: A cohort of 151 consecutive patients with early stage HCC (122 Child-Pugh class A and 29 class B patients) treated with RFA were enrolled. Clinical, laboratory and radiological follow-up data were collected from the time of first RFA. A single lesion was observed in 113/151 (74.8%), two lesions in 32/151 (21.2%), and three lesions in 6/151 (4%) of patients., Results: The overall survival rates were 94%, 80%, 64%, 49%, and 41% at 12, 24, 36, 48 and 60 months, respectively. Complete response (CR) at 1 month (p<0.0001) and serum albumin levels (p = 0.0004) were the only variables indipendently linked to survival by multivariate Cox model. By multivariate analysis, tumor size (p = 0.01) is the only variable associated with an increased likehood of CR. The proportion of major complications after treatment was 4%., Conclusions: RFA is safe and effective for managing HCC with cirrhosis, especially for patients with HCC ≤3 cm and higher baseline albumin levels. Complete response after RFA significantly increases survival.

A 63-year-old Caucasian man presented with a cholestatic syndrome, renal failure and arthralgias. A laboratory examination revealed high immunoglobulin G (IgG) and IgG4 levels (5.95 g/L; normal range: 0.08-1.4 g/L), pointing to a diagnosis of systemic IgG4-related disease, with definite radiological evidence of biliary and pancreatic expression, and plausible renal, articular, salivary and lacrimal glands involvement. Due to the rarity of the condition, there are currently no random control trials to point to the optimal therapeutic approach. The patient has been on steroid therapy with the subsequent introduction of azathioprine, with a complete resolution of all symptoms, a rapid reduction to normalization of all blood tests, and a complete regression of the radiological picture. Our experience underlines the complexity of IgG4-related disease and its variable and sometimes progressive presentation, while pointing out the need for a careful and complete assessment for possible multi-organ involvement.

Hepatocellular carcinoma (HCC) has a high incidence all over the world. Even if the primary end point of treatment of HCC is survival, radiological response could be a surrogate end point of survival, and could have a key role in clinical management. Since 1950 several radiological response criteria have been applied; however, it was not until 2000 that specific criteria for HCC were introduced by the European Association for the Study of the Liver (EASL), and these were then standardized in 2010 with the development of the modified Response Evaluation Criteria for Solid Tumors (mRECIST) for HCC. The purpose of this brief review is to compare data in literature regarding the application and the performance of mRECIST in clinical practice, and to discuss unclear and open issues.

Primary biliary cirrhosis is a slowly progressive cholestatic autoimmune liver disease that mainly affects middle-aged women with an estimated prevalence ranging from 6.7 to 402 cases per million. Hereditary hemorrhagic telangiectasia, or Rendu-Osler-Weber disease, is an autosomal dominant disorder characterized by angiodysplastic lesions (telangiectases and arteriovenous malformations) that can affect many organs, including liver, with a prevalence of 1-2 cases per 10000. We describe the coexistence, for the first time to our knowledge, of these two rare diseases in a 50-year old Caucasian woman. In this setting, the relevance of an accurate medical history, the role of liver histology and the characterization of liver involvement through dynamic imaging techniques can be emphasized.

Hepatocellular carcinoma is a major health problem. It is the sixth most common cancer worldwide and the third most common cause of cancer-related death. Despite the availability of several treatment opportunities, diagnosis is still made in an advanced phase, limiting application of most therapeutic choices that currently are based on the Barcelona Clinic Cancer Liver Classification and include surgical resection, orthotopic liver transplantation and ablative methods for very early and early disease, arterial chemoembolization for intermediate stages and systemic therapy with sorafenib for advanced hepatocellular carcinoma. Thanks to novel advancements in knowledge of molecular pathogenesis of this tumor, many new systemic agents and locoregional treatments are in different stages of clinical development and they represent an important promise of further improvements in patients' survival.

Unlabelled: The purpose was to assess the cost-effectiveness of sorafenib in the treatment of hepatocellular carcinoma (HCC) patients incorporating current prices and the results of the recent published field practice SOraFenib Italian Assessment (SOFIA) study. We created a Markov Decision Model to evaluate, in a hypothetical cohort of Caucasian male patients, aged 67 years with Barcelona Clinic Liver Cancer (BCLC) C HCC, or BCLC B HCC who were unfit or failed to respond to locoregional therapies, well compensated cirrhosis, and with performance status 0-1 according to Eastern Cooperative Oncology Group (ECOG), the cost-effectiveness of the following strategies: (1) full or dose-adjusted sorafenib for BCLC B and C patients together; (2) full or dose-adjusted sorafenib for BCLC B patients; (3) full or dose-adjusted sorafenib for BCLC C patients. Outcomes include quality-adjusted life years (QALYs), costs, and incremental cost-effectiveness ratio (ICER). In the base-case analysis dose-adjusted sorafenib was the most effective of the evaluated strategies. For dose-adjusted sorafenib, QALY was 0.44 for BCLC B and C patients together, 0.44 for BCLC C patients, and 0.38 for BCLC B patients. The ICER of dose-adjusted sorafenib compared with BSC was €34,534 per QALY gained for BCLC B and C patients together, €27,916 per QALY gained for BCLC C patients, and €54,881 per QALY gained for BCLC B patients. Results were sensitive to BSC survival rate, and sorafenib treatment duration., Conclusion: In daily practice dose-adjusted, but not full-dose, sorafenib is a cost-effective treatment compared to BSC in intermediate and advanced HCC., (Copyright © 2013 American Association for the Study of Liver Diseases.)

Hepatocellular carcinoma (HCC) is a major health problem. The treatment of HCC depends on the tumour stage and on the severity of underlying cirrhosis, however, a majority of HCC patients have advanced disease at presentation. In recent years extra-hepatic spread (ES) of HCC seems to have been observed more frequently than in the past even if few data exist in literature on prevalence, clinical presentation and prognosis of patients with HCC ES. Aim of this brief review is underline the main concerns, pitfalls and warnings in practicing with these patients. ES of HCC are not rare, and the probability of finding ES is higher in patients with advanced intra-hepatic HCC. The more frequent ES sites are lung lymph nodes and bones, but also the head and neck district can be affected. The prognosis of HCC patients with ES is poor and sorafenib seems to be the only therapeutic option.

Aim: To investigate the clinical course of untreatable hepatocellular carcinoma (HCC) identified at any stage and to identify factors associated with mortality., Methods: From January 1999 to December 2010, 320 out of 825 consecutive patients with a diagnosis of HCC and not appropriate for curative or palliative treatments were followed and managed with supportive therapy. Cirrhosis was diagnosed by histological or clinical features and liver function was evaluated according to Child-Pugh score. The diagnosis of HCC was performed by Ultra-Sound guided biopsy or by multiphasic contrast-enhanced computed tomography or gadolinium-enhanced magnetic resonance imaging. Data were collected for each patient including all clinical, laboratory and imaging variables necessary for the outcome prediction staging systems considered. HCC staging was performed according Barcelona Clinic Liver Cancer (BCLC) and Cancer of the Liver Italian Program scores. Follow-up time was defined as the number of months from the diagnosis of HCC to death. Prognostic baseline variables were analyzed by multivariate Cox analysis to identify the independent predictors of survival., Results: Seventy-five per cent of patients had hepatitis C. Ascites was present in 169 patients (53%), while hepatic encephalopathy was present in 49 patients (15%). The Child-Pugh score was class A in 105 patients (33%), class B in 142 patients (44%), and class C in 73 patients (23%). One hundred patients (31%) had macroscopic vascular invasion and/or extra-hepatic spread of the tumor. A single lesion > 10 cm was observed in 34 patients (11%), while multinodular HCC was present in 189 patients (59%). Thirty nine patients (12%) were BCLC early (A) stage, 55 (17%) were BCLC intermediate (B) stage, 124 (39%) were BCLC advanced (C) stage, and 102 (32%) were end-stage BCLC (D). At the time of this analysis (July 2011), 28 (9%) patients were still alive. Six (2%) patients who were lost during follow-up were censored at the last visit. The overall median survival was 6.8 mo, and the 1-year survival was 32%. The 1-year survival according to BCLC classes was 100%, 79%, 12% and 0%, for BCLC A, B, C and D, respectively. There was a significant difference in survival between each BCLC class. The median survival of patients of BCLC stages A, B, C and D was 33, 17.4, 6.9, and 1.8 mo, respectively (P < 0.05 for comparison between stages). The median survival of Child-Pugh A, B and C classes were 9.8 mo (range 6.4-13), 6.1 (range 4.9-7.3), and 3.7 (range 1.5-6), respectively (P < 0.05 for comparison between stages). By univariate analysis, the variables significantly associated to an increased liklihood of mortality were Eastern Cooperative Oncology Group performance status (PS), presence of ascites, low level of albumin, elevated level of bilirubin, international normalized ratio (INR) and Log-[(α fetoprotein (AFP)]. At multivariate analysis, mortality was independently predicted by bad PS (P < 0.0001), high INR values (P = 0.0001) and elevated Log-(AFP) levels (P = 0.009)., Conclusion: This study confirms the heterogeneous behavior of untreated HCC. BCLC staging remains an important prognostic guide and may be important in decision-making for palliative treatment.

Hepatocellular carcinoma (HCC) is a challenging malignancy of global importance. It is associated with a high rate of mortality and its prevalence in the United States and in Western Europe is increasing. Cirrhosis is the strongest and the most common known risk factor for HCC, usually due to hepatitis C virus (HCV) and hepatitis B virus (HBV) infections. However, different lines of evidence identify in non-alcoholic fatty liver disease (NAFLD) a possible relevant risk factor for occurrence of HCC. Given the continuing increase in the prevalence of obesity and diabetes, the incidence of non-alcoholic steatohepatitis-related HCC may also be expected to increase, and a potential role of behavior treatment and/or insulin-sensitizing drugs can be envisaged. Vaccination against HBV is the most efficient primary prevention measure currently available to reduce the HCC incidence and mortality in high-incidence areas, while data on the role of interferon (IFN) and nucleos(t)ide analogues (NUC) are still controversial. The pooling of data from the literature suggests a slight preventive effect of antiviral therapy on HCC development in patients with HCV-related cirrhosis, but the preventive effect is limited to sustained virological responders., (Copyright © 2012 Elsevier Inc.

Objective: To assess contrast-enhanced US (CEUS), computed tomography (CT) and magnetic resonance (MR) imaging findings and serial changes of the treated area at follow-up in patients who underwent liver resection using a bipolar radiofrequency electrosurgical device., Methods: Imaging findings of 27 patients with resected hepatocellular carcinomas (HCCs) (n=24) and metastases (n=3) (mean size: 2.6cm), were retrospectively evaluated. Two readers assessed: the (a) presence, (b) thickness, (c) shape and (d) echogenicity (CEUS)/attenuation (CT)/signal intensity (MR imaging) at coagulated site and the (e) presence of residual tumor of the bipolar radiofrequency electrosurgical device resection margin., Results: Follow-up was performed with either CT (n=20) or MR imaging (n=7) and repeated in 16 patients with CT (n=7), MR imaging (n=4), or both techniques (n=5). Four patients also had a single CEUS examination. At first imaging follow-up a peripheral halo was depicted at resection site (100%). A fluid collection within the surgical area was found in 67% of patients. During the following imaging examinations a progressive involution of both findings was observed, respectively, in 81% and 62% of patients. Viable tissue was detected in three patients (11%)., Conclusions: After liver resection with bipolar radiofrequency electrosurgical device successfully ablated tumor is demonstrated at imaging by an unenhancing partial linear peripheral halo, in most cases, surrounding a fluid collection reducing in size during follow-up., (Copyright © 2011 Elsevier Ireland Ltd.

Cirrhosis is a major cause of morbidity and mortality and is the end stage of any chronic liver disease. Cancer, a leading cause of death worldwide, is a growing global health issue. There are limited data in the literature on the incidence, prevalence and management of non-hepatic cancers (NHC) in cirrhotic patients. The aim of this brief review was to underline the main concerns, pitfalls and warnings regarding practice for these patients. Survival of patients with compensated cirrhosis is significantly longer than that of decompensated cirrhosis and patients with NHC and in Child-Pugh class C should not be candidates for cytotoxic chemotherapy. It is important before starting cytotoxic chemotherapy to assess the aetiology and stage of liver disease and to screen these patients for portal hypertension and fluid retention. During cytotoxic chemotherapy, the effectiveness of cancer treatment, as well the appearance of early signs of hepatic decompensation, must be thoroughly monitored. Future phase 3 trial designs in oncology should include a share of patients with compensated cirrhosis to obtain specific information in this setting. Identification of tests able to measure the global degree of hepatic impairment caused by cirrhosis could help in the management of this particular clinical situation., (© 2011 John Wiley & Sons A/S.)

Sorafenib (Nexavar®, Bayer), a multi-targeted tyrosine kinase inhibitor, was the first systemic agent that demonstrated a significant improvement in the overall survival in patients with advanced hepatocellular carcinoma and well-preserved liver function. This drug is now recommended in patients with advanced hepatocellular carcinoma as first-line therapy and for patients not suitable for locoregional treatment. This brief article, produced by a multidisciplinary panel including specialists in gastroenterology and oncology, provides an overview of the major issues related to systemic treatment of hepatocellular carcinoma with sorafenib, including staging and prognostic strategies, assessment of liver disease and its complications, and efficacy and safety of this molecule. Particular emphasis is given on how to improve tolerability of sorafenib in difficult-to-treat patients.

Unlabelled: A multicenter randomized controlled trial established sorafenib as a standard of care for patients with advanced hepatocellular carcinoma (HCC). Because the study was prematurely interrupted due to survival benefits in the sorafenib arm, we conducted an observational study to adequately assess risks and benefits of this regimen in field practice. Starting in 2008, all clinically compensated patients with advanced HCC and those with an intermediate HCC who were unfit or failed to respond to ablative therapies were consecutively evaluated in six liver centers in Italy, for tolerability as well as radiologic and survival response to 800-mg/d sorafenib therapy. Treatment was down-dosed or interrupted according to drug label. Two hundred ninety-six patients (88% Child-Pugh A, 75% Barcelona Clinic Liver Cancer [BCLC]-C, and 25% BCLC-B) received sorafenib for 3.8 months (95% CI 3.3-4.4). Two hundred sixty-nine (91%) patients experienced at least one adverse event (AE), whereas 161 (54%) had to reduce dosing. Treatment was interrupted in 103 (44%) for disease progression, in 95 (40%) for an AE, and in 38 (16%) for liver deterioration. The median survival was 10.5 months in the overall cohort, 8.4 months in BCLC-C versus 20.6 months in BCLC-B patients (P < 0.0001), and 21.6 months in the 77 patients treated for >70% of the time with a half dose versus 9.6 months in the 219 patients treated for >70% of the time with a full dose. At month 2 of treatment, the overall radiologic response was 8%. Eastern Cooperative Oncology Group performance status, macrovascular invasion, extrahepatic spread of the tumor, radiologic response at month 2, and sorafenib dosing were independent predictors of shortened survival., Conclusion: Overall, safety, effectiveness, and generalizability of sorafenib therapy in HCC was validated in field practice. The effectiveness of half-dosed sorafenib may have implications for tailored therapy., (Copyright © 2011 American Association for the Study of Liver Diseases.)

Background: Transarterial chemoembolisation (TACE) is first-line treatment in unresectable hepatocellular carcinoma (HCC) and rescue treatment after failure of radical treatments in early stage HCC. Prognostic tools for HCC using time-fixed Cox models may be unreliable in patients treated with TACE because time-varying predictors interact., Aim: To explore time-dependent variables as survival predictors in patients with HCC receiving TACE as first-line or second-line treatment., Methods: Eighty four consecutive patients with HCC (mean age 68; male gender 62%; Child-Pugh class: A n=73, B n=11; Barcelona Clinic Liver Cancer class: A n=44, B n=24, C n=16) treated with TACE were enrolled. Clinical, laboratory and radiological follow-up data were collected from the time of first treatment. Time-fixed and time-dependent Cox analyses were done., Results: Overall survival rates were 89.6% (95% CI 82.5-97.2) at 12months, 58.8% (95% CI 46.2-74.9) at 24, 35.4% (95% CI 22.3-56.1) at 36 and 17.2% (95% CI 7.0-41.7) at 48months. Performance status (P<0.001), number of nodules (P<0.016) and prior therapy (P=0.017) were the only variables strongly linked to survival by time-fixed Cox model. Performance status (P<0.001), prior therapy (P=0.005), number of treatments (P=0.013), complete response after TACE (P=0.005) and bilirubin level (P<0.001) were associated with survival using a time-dependent Cox model., Conclusions: Survival after TACE is influenced most by performance status, complete response and bilirubin. Compared with the time-fixed models, a time-dependent Cox model has the potential to estimate a more precise prognosis in HCC patients treated with TACE., (© 2011 Blackwell Publishing Ltd.)

Hepatocellular carcinoma (HCC) is a major health problem. It is currently the third cause of cancer-related death, it is highly prevalent in the Asia-Pacific region and Africa, and is increasing in Western countries. The natural history of HCC is very heterogeneous and prediction of survival in individual patients is not satisfactory because of the wide spectrum of the disease. During the past decade, major advances have been achieved in prevention, through better surveillance of patients at risk, and in therapy through better surgical and ablative therapies and multimodal treatment approaches. Moreover, the increasing knowledge of molecular hepatocarcinogenesis provides the opportunity for targeted therapies. In this setting, the impact of sorafenib on advanced-stage HCC is a landmark finding in the treatment of liver cancer. The role of sorafenib administration as adjuvant therapy after curative treatment is being evaluated in clinical studies. Future research should lead to a molecular classification of the disease and a more personalized treatment approach.
