Background & Aims Obeticholic acid (OCA) has recently been restricted in patients with primary biliary cholangitis (PBC) with "advanced cirrhosis" because of its narrow therapeutic index. We aimed to better define the predicting factors of hepatic serious adverse events (SAEs) and non-response in cirrhotic patients undergoing OCA therapy. Methods Safety and efficacy of treatment were evaluated in a cohort of consecutive PBC cirrhotic patients started with OCA. OCA response was evaluated according to the Poise criteria. Risk factors for hepatic SAEs and non-response were reported as risk ratios (RR) with 95% confidence intervals (CIs). Results One hundred PBC cirrhotics were included, 97 Child-Pugh class A and 3 class B. Thirty-one had oesophageal varices and 5 had a history of ascites. Thirty-three per cent and 32% of patients achieved a biochemical response at 6 and 12 months respectively. Male sex (adjusted-RR 1.75, 95%CI 1.42-2.12), INR (1.37, 1.00-1.87), Child-Pugh score (1.79, 1.28-2.50), MELD (1.17, 1.04-1.30) and bilirubin (1.83, 1.11-3.01) were independently associated with non-response to OCA. Twenty-two patients discontinued OCA within 12 months: 10 for pruritus, 9 for hepatic SAEs (5 for jaundice and/or ascitic decompensation; 4 for upper digestive bleeding). INR (adjusted-RR 1.91, 95%CI 1.10-3.36), lower albumin levels (0.18, 0.06-0.51), Child-Pugh score (2.43, 1.50-4.04), history of ascites (3.5, 1.85-6.5) and bilirubin (1.30, 1.05-1.56), were associated with hepatic SAEs. A total bilirubin >= 1.4 mg/dl at baseline was the most accurate biochemical predictor of hepatic SAEs under OCA. Conclusions An accurate baseline assessment is crucial to select cirrhotic patients who can benefit from OCA. Although OCA is effective in one third of cirrhotics, bilirubin level >= 1.4 mg/dl should discourage from its use.

Simple Summary This review proposes a comprehensive overview of the main prognostic systems for HCC classified as prognostic scores, staging systems, or combined systems. Prognostic systems for HCC are usually compared in terms of homogeneity, monotonicity of gradients, and discrimination ability. However, despite the great number of published studies comparing HCC prognostic systems, it is rather difficult to identify a system that could be universally accepted as the best prognostic scheme for all HCC patients encountered in clinical practice. In order to give a contribute in this topic, we conducted a study aimed at externally validate the MESH score and the CNLC classification using the ITA.LI.CA database. Abstract Prognostic assessment in patients with HCC remains an extremely difficult clinical task due to the complexity of this cancer where tumour characteristics interact with degree of liver dysfunction, patient general health status, and a large span of available treatment options. Several prognostic systems have been proposed in the last three decades, both from the Asian and European/North American countries. Prognostic scores, such as the CLIP score and the recent MESH score, have been generated on a solid statistical basis from real life population data, while staging systems, such as the BCLC scheme and the recent CNLC classification, have been created by experts according to recent HCC prognostic evidences from the literature. A third category includes combined prognostic systems that can be used both as prognostic scores and staging systems. A recent example is the ITA.LI.CA prognostic system including either a prognostic score and a simplified staging system. This review focuses first on an overview of the main prognostic systems for HCC classified according to the above three categories, and, second, on a comprehensive description of the methodology required for a correct comparison between different systems in terms of prognostic performance. In this second section the main studies in the literature comparing different prognostic systems are described in detail. Lastly, a formal comparison between the last prognostic systems proposed for each of the above three categories is performed using a large Italian database including 6882 HCC patients in order to concretely apply the comparison rules previously described.

Background: Sorafenib is the gold standard therapy for the advanced hepatocellular carcinoma (HCC). No scoring/staging is universally accepted to predict the survival of these patients. Aims: To evaluate the accuracy of the available prognostic models for HCC to predict the survival of advanced HCC patients treated with Sorafenib included in the Italian Liver Cancer (ITA.LI.CA.) multicenter cohort. Methods: The performance of several prognostic scores was assessed through a Cox regression-model evaluating the C-index and the Akaike Information Criterion (AIC). Results: Data of 1129 patients were analyzed. The mean age of patients was 61.6 years, and 80.8% were male. During a median follow-up period of 13 months, 789 patients died. The median period of Sorafenib administration was 4 months. All the prognostic scores were able to predict the overall survival (p

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

Background and aims the Barcelona Clinic Liver Cancer intermediate stage (BCLC-B) of hepatocellular carcinoma (HCC) includes extremely heterogeneous patients in terms of tumor burden and liver function. Transarterial-chemoembolization (TACE) is the first-line treatment for these patients although it may be risky/useless for someone, while others could undergo curative treatments. This study assesses the treatment type performed in a large cohort of BCLC-B patients and its outcome. Methods retrospective analysis of 485 consecutive BCLC-B patients from the ITA.LI.CA database diagnosed with naive HCC after 1999. Patients were stratified by treatment. Results 29 patients (6%) were lost to follow-up before receiving treatment. Treatment distribution was: TACE (233, 51.1%), curative treatments (145 patients, 31.8%), sorafenib (18, 3.9%), other (39, 8.5%), best supportive care (BSC) (21, 4.6%). Median survival (95% CI) was 45 months (37.4-52.7) for curative treatments, 30 (24.7-35.3) for TACE, 14 (10.5-17.5) for sorafenib, 14 (5.2-22.7) for other treatments and 10 (6.0-14.2) for BSC (p

Background: Dichotomous models like Milan Criteria represent the routinely used tools for predicting the outcome of patients with hepatocellular carcinoma (HCC). However, a paradigm shift from a dichotomous to continuous prognostic stratification should represent a good strategy for improving the prediction process. Recently, the tumor burden score (TBS) has been proposed for selecting patients with colorectal liver metastases. To date, TBS has not been validated in a large HCC population. The main objective of this study was to evaluate the prognostic power of TBS in an HCC population treated with different curative and palliative modalities. Methods: Prospectively collected data from consecutive HCC patients managed in 24 institutions participating in the ITA.LI.CA group between Jan 2002 and Mar 2015 were analyzed (n = 4759). A sub-analysis focused on 3909 patients with the radiological evidence of vascular invasion or metastatic disease was also performed. Results: TBS demonstrated the best discriminative ability when compared to MC and other tumor-specific scores. At multivariable Cox regression analysis, TBS was an independent risk factor of overall survival, with a 6% increased risk for patient death for each point increase in TBS. At survival analysis, when TBS ≥ 8 was connected with MELD ≥ 15 and alpha-fetoprotein ≥ 1000 ng/mL, patients presenting all these three risk factors presented the worst results (p value < 0.0001). Conclusions: Survival prediction of HCC patients was very well done using TBS model, even stratifying the population in relation to the presence of metastases and/or vascular invasion. TBS model was the best in terms of discriminatory ability and goodness of fit when compared with other continuous or binary variables. Its incorporation in a model composed by tumor- and liver function-related variables further increases its survival prediction.

Prognostic assessment of patients with hepatocellular carcinoma (HCC) at the time of diagnosis remains controversial and becomes even more complex at the time of restaging when new variables need to be considered. The aim of the current study was to evaluate the prognostic utility of restaging patients before proceeding with additional therapies for HCC. Two independent Italian prospective databases were used to identify 1,196 (training cohort) and 648 (validation cohort) consecutive patients with HCC treated over the same study period (2008-2015) who had complete restaging before decisions about additional therapies. The performance of the Italian Liver Cancer (ITA.LI.CA) prognostic score at restaging was compared with that of the Barcelona Clinic Liver Cancer, Hong Kong Liver Cancer, and Cancer of the Liver Italian Program systems. A multivariable Cox survival analysis was performed to identify baseline, restaging, or dynamic variables that were able to improve the predictive performance of the prognostic systems. At restaging, 35.3% of patients maintained stable disease; most patients were either down-staged by treatment (27.2%) or had disease progression (37.5%). The ITA.LI.CA scoring system at restaging demonstrated the best prognostic performance in both the training and validation cohorts (c-index 0.707 and 0.722, respectively) among all systems examined. On multivariable analysis, several variables improved the prognostic ability of the ITA.LI.CA score at restaging, including progressive disease after the first treatment, Model for End-Stage Liver Disease at restaging, and choice of nonsurgical treatment as additional therapy. A new ITA.LI.CA restaging model was created that demonstrated high discriminative power in both the training and validation cohorts (c-index 0.753 and 0.745, respectively). Conclusion: Although the ITA.LI.CA score demonstrated the best prognostic performance at restaging, other variables should be considered to improve the prognostic assessment of patients at the time of deciding additional therapies for HCC.

none 31 no Nonalcoholic fatty liver disease (NAFLD) represents the hepatic manifestation of metabolic syndrome and may evolve into hepatocellular carcinoma (HCC). Only scanty clinical information is available on HCC in NAFLD. The aim of this multicenter observational prospective study was to assess the clinical features of patients with NAFLD-related HCC (NAFLD-HCC) and to compare them to those of hepatitis C virus (HCV)-related HCC. A total of 756 patients with either NAFLD (145) or HCV-related chronic liver disease (611) were enrolled in secondary care Italian centers. Survival was modeled according to clinical parameters, lead-time bias, and propensity analysis. Compared to HCV, HCC in NAFLD patients had a larger volume, showed more often an infiltrative pattern, and was detected outside specific surveillance. Cirrhosis was present in only about 50% of NAFLD-HCC patients, in contrast to the near totality of HCV-HCC. Regardless of tumor stage, survival was significantly shorter (P = 0.017) in patients with NAFLD-HCC, 25.5 months (95% confidence interval 21.9-29.1), than in those with HCV-HCC, 33.7 months (95% confidence interval 31.9-35.4). To eliminate possible confounders, a propensity score analysis was performed, which showed no more significant difference between the two groups. Additionally, analysis of patients within Milan criteria submitted to curative treatments did not show any difference in survival between NAFLD-HCC and HCV-HCC (respectively, 38.6 versus 41.0 months, P = nonsignificant) CONCLUSIONS: NAFLD-HCC is more often detected at a later tumor stage and could arise also in the absence of cirrhosis, but after patient matching, it has a similar survival rate compared to HCV infection; a future challenge will be to identify patients with NAFLD who require more stringent surveillance in order to offer the most timely and effective treatment.

Background Hepatocellular carcinoma (HCC) is a heterogeneous disease with both tumor and liver factors being involved. Aims To investigate HCC clinical phenotypes and factors related to HCC size. Methods Prospectively-collected HCC patients' data from a large Italian database were arranged according to the maximum tumor diameter (MTD) and divided into tumor size terciles, which were then compared in terms of several common clinical parameters and patients' survival. Results An higer MTD tercile was significantly associated with increased blood alpha-fetoprotein (AFP), gamma-glutamyl transpeptidase (GGTP), and platelet levels. Patients with higher platelet levels had larger tumors and higher GGTP levels, with lower bilirubin levels. However, patients with the highest AFP levels had larger tumors and higher bilirubin levels, reflecting an aggressive biology. AFP correlation analysis revealed the existence of 2 different groups of patients: those with higher and with lower AFP levels, each with different patient and tumor characteristics. The Cox proportional-hazard model showed that a higher risk of death was correlated with GGTP and bilirubin levels, tumor size and number, and portal vein thrombosis (PVT), but not with AFP or platelet levels. Conclusions An increased tumor size was associated with increased blood platelet counts, AFP and GGTP levels. Platelet and AFP levels were important indicators of tumor size, but not of survival.

The prognosis of untreated patients with hepatocellular carcinoma (HCC) is heterogeneous, and survival data were mainly obtained from control arms of randomized studies. Clinical practice data on this topic are urgently needed, so as to help plan studies and counsel patients. We assessed the prognosis of 600 untreated patients with HCC managed by the Italian Liver Cancer Group. Prognosis was evaluated by subdividing patients according to the Barcelona Clinic Liver Cancer (BCLC) classification. We also assessed the main demographic, clinical, and oncological determinants of survival in the subgroup of patients with advanced HCC (BCLC C). Advanced (BCLC C: n = 138; 23.0%) and end-stage HCC (BCLC D; n = 210; 35.0%) represented the majority of patients. Overall median survival was 9 months, and the principal cause of death was tumor progression (n = 279; 46.5%). Patients' median survival progressively and significantly decreased as BCLC stage worsened (BCLC 0: 38 months; BCLC A: 25 months; BCLC B: 10 months; BCLC C: 7 months; BCLC D: 6 months; P 3) HCC (HR = 1.79; 95% CI = 1.21-2.63; P = 0.003) were independent predictors of survival in patients with advanced HCC (BCLC C). CONCLUSION: BCLC adequately predicts the prognosis of untreated HCC patients. In untreated patients with advanced HCC, female gender, clinical decompensation of cirrhosis, and multinodular tumor are independent prognostic predictors and should be taken into account for patient stratification in future therapeutic studies.

Eltrombopag is an oral thrombopoietin-receptor agonist. This study evaluated the efficacy of eltrombopag for increasing platelet counts and reducing the need for platelet transfusions in patients with thrombocytopenia and chronic liver disease who are undergoing an elective invasive procedure.We randomly assigned 292 patients with chronic liver disease of diverse causes and platelet counts of less than 50,000 per cubic millimeter to receive eltrombopag, at a dose of 75 mg daily, or placebo for 14 days before a planned elective invasive procedure that was performed within 5 days after the last dose. The primary end point was the avoidance of a platelet transfusion before, during, and up to 7 days after the procedure. A key secondary end point was the occurrence of bleeding (World Health Organization [WHO] grade 2 or higher) during this period.A platelet transfusion was avoided in 104 of 145 patients who received eltrombopag (72%) and in 28 of 147 who received placebo (19%) (P0.001). No significant difference between the eltrombopag and placebo groups was observed in bleeding episodes of WHO grade 2 or higher, which were reported in 17% and 23% of patients, respectively. Thrombotic events of the portal venous system were observed in 6 patients who received eltrombopag, as compared with 1 who received placebo, resulting in the early termination of the study. The incidence and severity of other adverse events were similar in the eltrombopag and placebo groups.Eltrombopag reduced the need for platelet transfusions in patients with chronic liver disease who were undergoing elective invasive procedures, but it was associated with an increased incidence of portal-vein thrombosis, as compared with placebo.

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 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.

Patients with hepatocellular carcinoma should be managed with a multidisciplinary approach framed in a network where all the diagnostic techniques and therapeutic resources are available in order to provide the optimal level of care.Given this assumption, the Coordinating Committee of the Italian Association for the Study of the Liver nominated a panel of experts to elaborate practical recommendations for the multidisciplinary management of hepatocellular carcinoma aiming to provide: (1) homogeneous and efficacious diagnostic and staging work-up, and (2) the best treatment choice tailored to patient status and tumour stage at diagnosis.The 2010 updated American Association for the Study of Liver Disease Guidelines for hepatocellular carcinoma were selected as the reference document. For each management issue, the American Association for the Study of Liver Disease recommendations were briefly summarised and discussed, according to both the scientific evidence published after their release and the clinical expertise of the Italian centres taking care of these patients. The Italian Association for the Study of the Liver expert panel recommendations are finally reported.

BACKGROUND & AIMS: This study investigates whether the aetiologic changes in liver disease and the improved management of hepatocellular carcinoma (HCC) have modified the clinical scenario of this tumour over the last 20 years in Italy. METHODS: Retrospective study based on the analysis of the ITA.LI.CA (Italian Liver Cancer) database including 3027 HCC patients managed in 11 centres. Patients were divided into 3 groups according to the period of HCC diagnosis: 1987-1996 (year of the "Milano criteria" publication), 1997-2001 (year of release of the EASL guidelines for HCC), and 2002-2008. RESULTS: The significant changes were: (1) progressive patient ageing; (2) increasing prevalence of HCV infection until 2001, with a subsequent decrease, when the alcoholic aetiology increased; (3) liver function improvement, until 2001; (4) increasing "incidental" at the expense of "symptomatic" diagnoses, until 2001; (5) unchanged prevalence of tumours diagnosed during surveillance (around 50%), with an increasing use of the 6-month schedule; (6) favourable HCC "stage migration", until 2001; (7) increasing use of percutaneous ablation; (8) improving survival, until 2001. CONCLUSIONS: Over the last 20 years, several aetiologic and clinical features regarding HCC have changed. The survival improvement observed until 2001 was due to an increasing number of tumours diagnosed in early stages and in a background of compensated cirrhosis, and a growing and better use of locoregional treatments. However, the prevalence of early cancers and survival did not increase further in the last years, a result inciting national policies aimed at implementing surveillance programmes for at risk patients.

Alpha-fetoprotein is a tumor marker that has been used for surveillance and diagnosis of hepatocellular carcinoma (HCC) in patients with cirrhosis. The prognostic capability of this marker in patients with HCC has not been clearly defined. In this study our aim was to evaluate the prognostic usefulness of serum alpha-fetoprotein in patients with well-compensated cirrhosis, optimal performance status, and small HCC identified during periodic surveillance ultrasound who were treated with curative intent. Among the 3,027 patients included in the Italian Liver Cancer study group database, we selected 205 Child-Pugh class A and Eastern Cooperative Group Performance Status 0 patients with cirrhosis with a single HCC ≤3 cm of diameter diagnosed during surveillance who were treated with curative intent (hepatic resection, liver transplantation, percutaneous ethanol injection, radiofrequency thermal ablation). Patients were subdivided according to alpha-fetoprotein serum levels (i.e., normal ≤20 ng/mL; mildly elevated 21-200 ng/mL; markedly elevated >200 ng/mL). Patient survival, as assessed by the Kaplan-Meier method, was not significantly different among the three alpha-fetoprotein classes (P = 0.493). The same result was obtained in the subgroup of patients with a single HCC ≤2 cm (P = 0.714). An alpha-fetoprotein serum level of 100 ng/mL identified by receiver operating characteristic curve had inadequate accuracy (area under the curve = 0.536, 95% confidence interval = 0.465-0.606) to discriminate between survivors and deceased patients. Conclusion: Alpha-fetoprotein serum levels have no prognostic meaning in well-compensated cirrhosis patients with single, small HCC treated with curative intent. (HEPATOLOGY 2012)

Objectives The number of elderly patients diagnosed with hepatocellular carcinoma (HCC) is expected to increase. We compared the presenting features and outcome of HCC in elderly (≥70 years) and younger patients ( Design Multicentre retrospective cohort study and nested case–control study. Patients 614 elderly and 1104 younger patients from the ITA.LI.CA database, including 1834 HCC cases consecutively diagnosed from January 1987 to December 2004. Both groups were stratified according to treatment: hepatic resection, percutaneous procedures, transarterial chemoembolisation (TACE). Survival was assessed in the whole population and in each treatment subgroup. Age, sex, aetiology, cirrhosis, comorbidities and cancer stage (CLIP score) were tested as predictors of survival. In each subgroup, differences in patient survival were also assessed after adjustment and matching by propensity score. Results Ageing was associated with a higher prevalence of comorbidities, better liver function and CLIP score. Regardless of age, two-thirds of patients underwent radical treatments or TACE. Elderly patients underwent more ablative procedures and fewer resections or TACE sessions. The survival of elderly and younger patients was comparable in each treatment subset, and was predicted by CLIP score. This result was confirmed by the propensity analysis. Conclusions The overall applicability of radical or effective HCC treatments was unaffected by old age. However, treatment distribution differed, elderly individuals being more frequently treated with percutaneous procedures and less frequently with resection or TACE. Survival was unaffected by age and primarily predicted by cancer stage, assessed by the CLIP system, both in the overall population and in treatment subgroups.

The current guidelines recommend the surveillance of cirrhotic patients for early diagnosis of hepatocellular carcinoma (HCC), based on liver ultrasonography repetition at either 6 or 12 month intervals, since there is no compelling evidence of superiority of the more stringent program. This study aimed at comparing cancer stage, treatment applicability, and survival between patients on semiannual or annual surveillance.We analyzed the clinical records of 649 HCC patients in Child-Pugh class A or B, observed in ITA.LI.CA centers. HCC was detected in 510 patients submitted to semiannual surveillance (Group 1) and in 139 submitted to annual surveillance (Group 2). In Group 1 the survival was presented as observed and corrected for the lead time.The cancer stage was less severe in Group 1 than in Group 2 (p0.001), with more single tiny (2 cm) and less advanced tumors. Treatment applicability was improved by the semiannual program (p=0.020). The median observed survival was 45 months (95% CI 40.0-50.0) in Group 1 and 30 months (95% CI 24.0-36.0) in Group 2 (p=0.001). The median corrected survival of Group 1 was 40.3 months (95% CI 34.9-45.7) (p=0.028 with respect to the observed survival of Group 2). Age, platelet count, alpha-fetoprotein, Child-Pugh class, cancer stage, and hepatocellular carcinoma treatment were independent prognostic factors.Semiannual surveillance increases the detection rate of very early hepatocellular carcinomas and reduces the number of advanced tumors as compared to the annual program. This translates into a greater applicability of effective treatments and into a better prognosis.

Previous work has shown that two general processes contribute to hepatocellular cancer (HCC) prognosis: liver damage, monitored by indices such as blood bilirubin, prothrombin time (PT), and aspartate aminostransferase (AST); and tumor biology, monitored by indices such as tumor size, tumor number, presence of portal vein thrombosis (PVT) and blood alpha-fetoprotein (AFP) levels. These processes may affect one another, with prognostically significant interactions between multiple tumor and host parameters. These interactions form a context that provide personalization of the prognostic meaning of these factors for every patient. Thus, a given level of bilirubin or tumor diameter might have a different significance in different personal contexts. We previously applied network phenotyping strategy (NPS) to characterize interactions between liver function indices of Asian HCC patients and recognized two clinical phenotypes, S and L, differing in tumor size and tumor nodule numbers. Our aim was to validate the applicability of the NPS-based HCC S/L classification on an independent European HCC cohort, for which survival information was additionally available. Four sets of peripheral blood parameters, including AFP-platelets, derived from routine blood parameter levels and tumor indices from the ITA.LI.CA database, were analyzed using NPS, a graph-theory-based approach that compares personal patterns of complete relationships between clinical data values to reference patterns with significant association to disease outcomes. Without reference to the actual tumor sizes, patients were classified by NPS into two subgroups with S and L phenotypes. These two phenotypes were recognized using solely the HCC screening test results, consisting of eight common blood parameters, paired by their significant correlations, including an AFP-platelets relationship. These trends were combined with patient age, gender, and self-reported alcoholism into NPS personal patient profiles. We subsequently validated (using actual scan data) that patients in L phenotype group had 1.5× larger mean tumor masses relative to S, P = 6 × 10(-16). Importantly, with the new data, liver test pattern-identified S-phenotype patients had typically 1.7× longer survival compared to L-phenotype patients. NPS integrated the liver, tumor, and basic demographic factors. Cirrhosis-associated thrombocytopenia was typical for smaller S tumors. In L tumor phenotype, typical platelet levels increased with the tumor mass. Hepatic inflammation and tumor factors contributed to more aggressive L tumors, with parenchymal destruction and shorter survival. NPS provides integrative interpretation for HCC behavior, identifying two tumor and survival phenotypes by clinical parameter patterns. The NPS classifier is provided as an Excel tool. The NPS system shows the importance of considering each tumor marker and parameter in the total context of all the other parameters of an individual patient.

BACKGROUND: Chronic hepatitis B virus (HBV) infection is one of the most frequent aetiological factors associated with the development of hepatocellular carcinoma (HCC). AIM: This study evaluated the temporal trend in the aetiological role played by HBV infection alone in patients diagnosed with HCC during the last 20 years in Italy. METHODS: Among the 2042 HCC patients included in the Italian Liver Cancer (ITA.LI.CA.) database, 346 had chronic HBV infection alone. We assessed the proportion of HCC patients with HBV infection in four quinquennia (1987-1991, 1992-1996, 1997-2001, 2002-2006) and evaluated their main clinical, virological and oncological characteristics across these periods. RESULTS: Although the absolute number increased, the proportion of HBV-related HCC relatively decreased over time from 26.7% (47/176 patients) in 1987-1991 to 14.7% (127/862 patients) in 2002-2006 (P=0.0005). Patients' demographical, clinical and virological characteristics were similar across the four quinquennia. A greater proportion of patients was diagnosed with non-advanced HCC in more recent years (from 26% in 1987-1991 to 48% in 2002-2006, P=0.025), likely owing to a growing use of semiannual surveillance (from 63% in 1987-1991 to 80% in 2002-2006). CONCLUSIONS: We observed a significant, relative decrease in the role played by chronic HBV infection alone in the determinism of HCC during the last 20 years. In recent years, more patients are diagnosed with non-advanced HCC probably owing to improvements in HCC detection.

Aberrant squamous cell carcinoma antigen (SCCA) expression is an early event in hepatocarcinogenesis, and increasing serum levels of SCCA variants IgM immune complexes (SCCA-IgM IC) have been found in cirrhotic patients developing hepatocellular carcinoma (HCC). We longitudinally evaluated a cohort of cirrhotic patients with hepatitis C virus infection (HCV) who underwent pegylated interferon (PEG-IFN) and ribavirin treatment. SCCA-IgM IC levels were assessed in the sera of 33 cirrhotic patients with HCV (21 males, median age 57 years) before, at the end and at 6-month and 1-year follow-up after treatment with PEG-IFN and ribavirin. SCCA-IgM IC serum levels (arbitrary units/mL, AU/mL) were evaluated according to treatment outcome: sustained virological response (SVR) vs nonresponse (NR). Overall, 15 patients obtained a SVR to antiviral therapy (45%). There was no significant difference in baseline SCCA-IgM IC serum levels between SVR and NR patients. When compared to baseline (451.2 AU/mL), SVR patients showed a significant decrease in median SCCA-IgM IC serum levels at the end of treatment (186.8 AU/mL, P = 0.013) and at both 6-month (96.8 AU/mL, P0.001) and 1-year follow-up (52.4 AU/mL, P0.001), while no significant modification was observed in NR patients. In patients with HCV-related liver cirrhosis, successful antiviral therapy is associated with a dramatic and significant decrease in SCCA-IC serum levels. Because of the pathophysiological correlation between SCCA and liver carcinogenesis, it is hypothesized that in patients with liver cirrhosis, SVR may be accompanied by a decreased proliferative stimulation.

There is a lack of information on the characteristics of patients with chronic hepatitis C virus infection (HCV) who fail to respond to antiviral treatment. We studied HCV-positive subjects with chronic liver diseases treated with pegylated-interferon (PEG-IFN) and ribavirin (RBV) who failed to clear HCV in routine clinical practice. A total of 2150 consecutive adult patients treated with PEG-IFN plus RBV therapy in 46 Italian centres between 1 July 2004, and 30 June 2005, were studied. Of the 2150 patients, 923 (42.9%) (M/F 585/335, mean age 54.8 years) failed to achieve a serum HCV-RNA clearance. Of these 923 patients, 429 (46.5%) were nonresponders, 298 (32.3%) relapsers, 168 (18.2%) drop-outs for noncompliance or adverse events and 28 (3.0%) were lost during follow-up. Overall, 642 (70.6%) patients received adequate therapy (defined as more than 80% of the drug doses for >80% of the time). Genotypes 1-4 were observed in 76.9% of cases; genotypes 2-3 in 21.2% and mixed in 1.9%, respectively. Multiple logistic regression analysis identified genotypes 1 and 4 as the sole independent predictors of the likelihood of nonresponse to therapy compared with relapse (OR: 4.38; 95% CI = 2.28-8.4). Age older than 65 years was the sole independent factor associated with no adherence to therapy (OR: 2.22; 95% CI = 1.36-3.62). Patients who fail to respond to treatment are a nonhomogeneous population with different features, and the sole factor that discriminates nonresponse from relapse is the distribution of genotypes 1-4. Co-morbidities are unable to determine the type of treatment failure and inadequate adherence to therapy mostly affects patients older than 65 years of age. © 2009 Blackwell Publishing Ltd.

The aim of this study was to determine the prevalence of hepatitis B virus (HBV) infection in an Italian region, Liguria (1,572,000 inhabitants), by means of a network of 12 referral centers for liver diseases. All patients with HBV surface antigen followed throughout 2006 were included. Personal data, infectious status with risk factors, other non-infectious risk factors for liver disease, clinical status, and treatment were the questionnaire. Four hundred forty-five patients (71% male) were evaluated. Their median age was 48 years (range 5–84), and 83.4% were of Italian origin. Community-acquired infection was the principal mode of HBV transmission (82.5%), followed by previous intravenous drug use (9.4%), perinatal transmission (6.3%), and transfusion-associated transmission (1.8%). Hepatitis B e-antigen was present in 20.4% of the patients, while co-infections with hepatitis D virus and/or hepatitis C virus and/or human immunodeficiency virus (HIV) were observed in 18.7% of the patients. Chronic active hepatitis was present in 62.5% of the patients, cirrhosis in 13.5%, hepatocellular carcinoma in 2.2%, and 21.8% of the patients were inactive carriers of HBV. In all, 42.5% of the patients were treated with interferon or lamivudine and/or adefovir-dipivoxil. Forty-nine patients were co-infected with HIV (86% on highly active antiviral therapy). Nevertheless, this study identified only 2.2% of the expected patients with HBV. Hence, it has to be reasoned that few potential infectious or treatable patients are referred to liver disease centers. HBV infection is still an underestimated health problem, and few potential infectious or treatable patients are referred to tertiary centers. J. Med.

Hepatitis C virus (HCV) infection is now considered a systemic disease due to the occurrence of extra-hepatic manifestations. Among these, the renal involvement is frequent. HCV infection, in fact, is strongly associated with proteinuria and chronic kidney disease (CKD) and negatively affects the prognosis of renal patients. In the last few years, availability of more specific and effective drugs against HCV has dramatically changed the clinical course of this disease. These drugs may provide further advantages in the CKD population as a whole by reducing progression of renal disease, mortality rate and by increasing the survival of graft in renal transplant recipients. The strict pathogenetic and prognostic link between HCV infection and CKD requires an ongoing relationship among the healthcare professionals involved in the treatment of both HCV infection and CKD. Therefore, Scientific Societies involved in the care of this high-risk population in Italy have organized a joint expert panel. The aim of the panel is to produce a position statement that can be used in daily clinical practice for the management of HCV infected patients across the whole spectrum of renal disease, from the conservative phase to renal replacement treatments (dialysis and transplantation). Sharing specific evidence-based expertise of different professional healthcare is the first step to obtain a common ground of knowledge on which to instate a model for multidisciplinary management of this high-risk population. Statements cover seven areas including epidemiology of CKD, HCV-induced glomerular damage, HCV-related renal risk, staging of liver disease in patients with CKD, prevention of transmission of HCV in hemodialysis units, treatment of HCV infection and management of HCV in kidney transplantation.

The Barcelona Clinic Liver Cancer advanced stage (BCLC C) of hepatocellular carcinoma (HCC) includes a heterogeneous population, where sorafenib alone is the recommended treatment. In this study our aim was to assess treatment and overall survival (OS) of BCLC C patients sub-classified according to clinical features (Performance Status [PS], macro-vascular invasion [MVI], extra-hepatic spread [EHS] or MVI+EHS) determining their allocation to this stage. From the Italian Liver Cancer database, we analysed 835 consecutive BCLC C patients diagnosed between 2008 and 2014. Patients were sub-classified as: PS1 alone (n=385, 46.1%), PS2 alone (n=146, 17.5%), MVI (n=224, 26.8%), EHS (n=51, 6.1%) and MVI+EHS (n=29, 3.5%). MVI, EHS and MVI+EHS patients had larger and multifocal/massive HCCs and higher alpha-fetoprotein levels than PS1 and PS2 patients. Median OS significantly declined from PS1 (38.6 months) to PS2 (22.3 months), EHS (11.2 months), MVI (8.2 months) and MVI+EHS (3.1 months) (P

The present document is a second contribution collecting the recommendations of an expert panel of transplant hepatologists appointed by the Italian Association for the Study of the Liver (AISF) concerning the management of certain aspects of liver transplantation, including: the issue of prompt referral; the management of difficult candidates; malnutrition; living related liver transplants; hepatocellular carcinoma; and the role of direct acting antiviral agents before and after transplantation. The statements on each topic were approved by participants at the AISF Transplant Hepatology Expert Meeting organized by the Permanent Liver Transplant Commission in Mondello on 12-13 May 2017. They are graded according to the GRADE grading system.

Background: Few data are available on the virological and clinical outcomes of advanced liver disease patients retreated after first-line DAA failure. Aim: To evaluate DAA failure incidence and the retreatment clinical impact in patients treated in the advanced liver disease stage. Methods: Data on HCV genotype, liver disease severity, and first and second line DAA regimens were prospectively collected in consecutive patients who reached the 12-week post-treatment and retreatment evaluations from January 2015 to December 2016 in 23 of the PITER network centers. Results: Among 3,830 patients with advanced fibrosis (F3) or cirrhosis, 139 (3.6%) failed to achieve SVR. Genotype 3, bilirubin levels >1.5mg/dl, platelet count

Patients with cirrhosis present with hemostatic alterations secondary to reduced availability of pro-coagulant and anti-coagulant factors. The net effect of these changes is a rebalanced hemostatic system. The Italian Association of the Study of the Liver (AISF) and the Italian Society of Internal Medicine (SIMI) promoted a consensus conference on the hemostatic balance in patients with cirrhosis. The consensus process started with the review of the literature by a scientific board of experts and ended with a formal consensus meeting in Rome in December 2014. The statements were graded according to quality of evidence and strength of recommendations, and approved by an independent jury. The statements presented here highlight strengths and weaknesses of current laboratory tests to assess bleeding and thrombotic risk in cirrhotic patients, the pathophysiology of hemostatic perturbations in this condition, and outline the optimal management of bleeding and thrombosis in patients with liver cirrhosis.

Summary Background Hepatocellular carcinoma (HCC) causes premature death and loss of life expectancy worldwide. Its primary and secondary prevention can result in a significant number of years of life saved. Aim To assess how many years of life are lost after HCC diagnosis. Methods Data from 5346 patients with first HCC diagnosis were used to estimate lifespan and number of years of life lost after tumour onset, using a semi-parametric extrapolation having as reference an age-, sex- and year-of-onset-matched population derived from national life tables. Results Between 1986 and 2014, HCC lead to an average of 11.5 years-of-life lost for each patient. The youngest age-quartile group (18–61 years) had the highest number of years-of-life lost, representing approximately 41% of the overall benefit obtainable from prevention. Advancements in HCC management have progressively reduced the number of years-of-life lost from 12.6 years in 1986–1999, to 10.7 in 2000–2006 and 7.4 years in 2007–2014. Currently, an HCC diagnosis when a single tumour
