    ABSTRACT: Objective: To perform a systematic review of worldwide literature on laparoscopic liver resections (LLR) and compare short-term outcomes against open liver resections (OLR) by meta-analyses. Summary background data: There are no updated pooled data since 2009 about the current status and short-term outcomes of LLR worldwide. Patients and methods: All English language publications on LLR were screened. Descriptive worldwide data and short-term outcomes were obtained. Separate analyses were performed for minor-only and major-only resection series, and series in which minor/major resections were not differentiated. Apparent case duplications were excluded. Results: A set of 463 published manuscripts were reviewed. One hundred seventy-nine single-center series were identified that accounted for 9527 LLR cases worldwide. Minor-only, major-only, and combined major-minor series were 61, 18, and 100, respectively, including 32, 8, and 43 comparative series, respectively. Of the total 9527 LLR cases reported, 6190 (65%) were for malignancy and 3337 (35%) were for benign indications. There were 37 deaths reported (mortality rate = 0.4%). From the meta-analysis comparing case-matched LLR to OLR (N = 2900 cases), there was no increased mortality and significantly less complications, transfusions, blood loss, and hospital stay observed in LLR vs OLR. Conclusions: This is the largest review of LLR available to date with over 9000 cases published. It confirms growing safety when performed in selected patients and by trained surgeons, and suggests that LLR may offer improved patient short-term outcomes compared with OLR. Improved levels of evidence, standardized reporting of outcomes, and assuring proper training are the next challenges of laparoscopic liver surgery.

    ABSTRACT: To analyse the impact of liver resection (LR) in patients with Hepatocellular Carcinoma (HCC) within the Barcelona-Clinic-Liver-Cancer (BCLC)-B stage. Analysis of patients with BCLC-B HCC treated with LR or transarterial chemoembolization (TACE) between 2007 and 2012 in our hospital. Survival/recurrence analyses were performed by log-rank tests and Cox multivariate models. Further analyses were specifically obtained for the HCC subclassification (B1-2-3-4) proposed recently. Eighty patients were treated (44-TACE/36-LR). Number of nodules was [1.8(1.1)], being multinodular in 50% of cases. Although resected patients had a higher hospital stay than those who underwent TACE (14 ± 13 vs 7 ± 6; P = 0.004), the rate and severity of complications was lower measured by Dindo-Clavien scale (P < 0.05). Overall survival was 40% with a median follow-up of 29.5 months (0.07-96.9). Five-years survival rates were 62.9%, 28.1% and 15.4%, respectively (P = 0.004) for B1, B2 and B3-4 stages. Cox model showed that only total bilirubin [OR = 2.055(1.23-3.44)] and BCLC subclassification B3-4 [OR = 2.439(1.04-5.7)] and B2 [OR = 2.79(1.35-5.77)] vs B1 were independent predictors of 5-years-survival. In B1 patients, surgical approach led a significant decrease in 5-years recurrence-rate (25% vs 60%; P = 0.018). In the surgical subgroup analysis, better results were observed if well/moderate differentiation combined with no microvascular-invasion (VI) in 5-years-survival (84.6%; P = 0.001) and -recurrence (23.1%; P = 0.041), respectively. These survival and recurrence trends were remarkable in B1 stages. Management of Intermediate BCLC-B HCC stage should be more complex and include updated criteria regarding B-stage subclassifications, VI and tumour differentiation. Modern surgical resection would offer improved survival benefit with acceptable safety in selected BCLC-B stage patients. Copyright © 2015 Elsevier Ltd. All rights reserved.

    ABSTRACT: Hepatocellular carcinoma (HCC) is one of the most common and lethal cancers in the world, with limited options for treatment unless timely diagnosed. Chronic hepatitis C virus (HCV) infection and persistent heavy alcohol consumption are independent risk factors for HCC development, which may induce a specific protein expression pattern different from those caused separately. The aim of the study was to identify protein biomarkers for the detection of HCC in HCV-infected alcoholic patients with cirrhosis in order to improve survival. We compared protein expression profiles of plasma samples from 52 HCV-infected alcoholic patients with and without HCC, using 2-D DIGE coupled with MALDI-TOF/TOF mass spectrometry. The 2-D DIGE results were analyzed statistically using Decyder software, and verified by western-blot and ELISA. In plasma samples from HCV-infected alcoholic patients, we found significantly differential expression profiles of carboxypeptidase-N, ceruloplasmin (CP), complement component 4a (C4a), fibrinogen-alpha (FGA), immunoglobulin mu chain C region, serum albumin, and serum paraoxonase/arylesterase 1 (PON1). Deregulation of plasma/serum levels of the identified proteins was associated to HCV, ethanol consumption, and/or HCC progression. In the validation through ELISA, C4a serum concentration was increased in HCC patients (2.4±1 ng/mg vs 1.8±0.6 ng/mg; p = 0.029), being the only independent predictor of HCC in the multivariate analysis (OR = 2.15; p = 0.015), with an AUROC = 0.70. The combination of C4a, FGA, CP and PON1 improved slightly the predictive ability of C4a alone (AUROC 0.81). In conclusion, we identified proteins related to acute-phase response, oxidative stress, or immune response, whose differential expression in plasma may be attributed to the presence of HCC. Among them, C4a, and its combination with CP, FGA and PON1, could be considered as potentially reliable biomarkers for the detection of HCC in HCV-infected alcoholic patients.

    ABSTRACT: The gold standard to diagnose acute cellular rejection (ACR) after liver transplantation (LT) is histological evaluation, but there is no consensus to select patients for liver biopsy. We aimed to evaluate the agreement among clinicians to select candidates for liver biopsy early after LT. From a protocol biopsy population (n=690) we randomly selected 100 LT patients in whom the biopsy was taken 7-10 days after LT. The clinical information between LT and protocol biopsy was given to 9 clinicians from 3 transplant centres who decided if a liver biopsy was needed. The agreement among clinicians to select candidates for liver biopsy was poor: κ=0.06-0.62, being κ<0.40 in 76% of comparisons. The concordance between indication for liver biopsy and moderate-severe ACR in the protocol biopsy was κ<0.30 in all cases. A multivariate model based on the product age-by-MELD (OR=0.81; p=0.013), delta eosinophils (OR=1.5; p=0.002), and mean tacrolimus trough concentrations <6ng/mL within the prior 4 days (OR=11.4; p=0.047), had an AUROC=0.84 to diagnose moderate-severe histological ACR. In conclusion, the agreement among clinicians to select patients for liver biopsy is very poor. If further validated the proposed model would provide an objective method to select candidates for liver biopsy after LT.This article is protected by copyright. All rights reserved.

    ABSTRACT: Background & aims: There is an increasing discrepancy between the number of potential liver graft recipients and the number of organs available. Organ allocation should follow the concept of benefit of survival, avoiding human-innate subjectivity. The aim of this study is to use artificial-neural-networks (ANNs) for donor-recipient (D-R) matching in liver transplantation (LT) and to compare its accuracy with validated scores (MELD, D-MELD, DRI, P-SOFT, SOFT, and BAR) of graft survival. Methods: 64 donor and recipient variables from a set of 1003 LTs from a multicenter study including 11 Spanish centres were included. For each D-R pair, common statistics (simple and multiple regression models) and ANN formulae for two non-complementary probability-models of 3-month graft-survival and -loss were calculated: a positive-survival (NN-CCR) and a negative-loss (NN-MS) model. The NN models were obtained by using the Neural Net Evolutionary Programming (NNEP) algorithm. Additionally, receiver-operating-curves (ROC) were performed to validate ANNs against other scores. Results: Optimal results for NN-CCR and NN-MS models were obtained, with the best performance in predicting the probability of graft-survival (90.79%) and -loss (71.42%) for each D-R pair, significantly improving results from multiple regressions. ROC curves for 3-months graft-survival and -loss predictions were significantly more accurate for ANN than for other scores in both NN-CCR (AUROC-ANN=0.80 vs. -MELD=0.50; -D-MELD=0.54; -P-SOFT=0.54; -SOFT=0.55; -BAR=0.67 and -DRI=0.42) and NN-MS (AUROC-ANN=0.82 vs. -MELD=0.41; -D-MELD=0.47; -P-SOFT=0.43; -SOFT=0.57, -BAR=0.61 and -DRI=0.48). Conclusions: ANNs may be considered a powerful decision-making technology for this dataset, optimizing the principles of justice, efficiency and equity. This may be a useful tool for predicting the 3-month outcome and a potential research area for future D-R matching models.

    ABSTRACT: Liver donation is the cornerstone for the expansion of liver transplantation. Although big efforts have been performed to release alternatives for increasing the donor pool, only extended-criteria donors have become a feasible option. The success of the Spanish Model for organ transplantation is well known. Approximately 5.4% of all the liver transplants (LT) are performed in Spain, with a rate of 22.9 LT per million people (pmp). Approximately 70 papers on extended-criteria donors have been reported from Spanish LT teams. Pioneering works in donor steatosis, non-heart-beating donors, donor age-hepatitis C virus, ischemia/reperfusion injury, normothermic extracorporeal membrane oxygenation, and donor steatosis-hepatitis C virus are among the main contributions in the field. Considering data from the Spanish National Registry, it can be observed that an accumulation of donor and recipient factors leads to a continuum of risk for liver transplantation. Donors are not "bad" enough to decline a liver offer per se. In Spain, clear efforts should be made to work on more stable and homogeneous criteria for donor acceptance. In this sense, defining a specific Spanish donor risk index would be helpful.

    ABSTRACT: The current methods available for screening and detecting hepatocellular carcinoma (HCC) have insufficient sensitivity and specificity, and only a low percentage of diagnosis of small tumours is based on these assays. Because HCC is usually asymptomatic at potentially curative stages, identification of biomarkers for the early detection of HCC is essential to improve patient survival. The aim of this study was to identify candidate markers for HCC development in the plasma from hepatitis C virus (HCV)-infected cirrhotic patients. We compared protein expression profiles of plasma samples from HCV-infected cirrhotic patients with and without HCC, using two-dimensional fluorescence difference gel electrophoresis (2-D DIGE) coupled with MALDI-TOF/TOF mass spectrometry. The 2-D DIGE results were analysed statistically using Decyder™ software, and verified by western blot and enzyme-linked immunosorbent assay (ELISA). In the plasma of HCV-infected HCC patients, we observed decreased expression of complement component 9, ficolin-3 (FCN3), serum amyloid P component (SAP), fibrinogen-gamma and immunoglobulin gamma-1 chain, and increased expression of vitronectin (VTN) and galectin-3 binding protein (G3BP) by DIGE analysis. ELISA confirmed DIGE results for VTN and G3BP but not for SAP or FCN3 in a larger patient population. The proteins VTN and SAP are candidate biomarkers for HCC development in HCV-infected cirrhotic patients.

    ABSTRACT: Recurrence of hepatocellular carcinoma (HCC) is a major complication after liver transplantation (LT). The initial immunosuppression protocol may influence HCC recurrence, but the optimal regimen is still unknown. 219 HCC consecutive patients under Milan criteria who received a LT at 2 european centres between 2000-2010 were included. Median follow-up was 51 months (IQR 26-93). Demographic characteristics, HCC features, and immunosuppression protocol within the first month after LT were evaluated against HCC recurrence by using Cox regression. In the explanted liver 110 patients (50%) had multinodular HCC, and largest nodule diameter was 3±2.1 cm. Macrovascular invasion was incidentally detected in 11 patients (5%), and microvascular invasion was present in 41 patients (18.7%). HCC recurrence rates were 13.3% at 3 years and 17.6% at 5 years. HCC recurrence was not influenced by the use/non use of steroids and antimetabolites (p=0.69 and p=0.70 respectively), and was similar with tacrolimus or cyclosporine (p=0.25). Higher exposure to calcineurin inhibitors within the first month after LT (mean tacrolimus trough concentrations >10ng/mL or cyclosporine trough concentrations >300ng/mL), but not thereafter, was associated with increased risk of HCC recurrence (27.7% vs 14.7% at 5 years; p=0.007). The independent predictors of HCC recurrence by multivariate analysis were: high exposure to calcineurin inhibitors defined as above (RR=2.82; p=0.005), diameter of the largest nodule (RR=1.31; p<0.001), microvascular invasion (RR=2.98; p=0.003) and macrovascular invasion (RR=4.57; p=0.003). Immunosuppression protocols with early CNI minimization should be preferred in LT patients with HCC in order to minimize tumour recurrence.

    ABSTRACT: Hepatitis C virus (HCV) is a major health problem that leads to chronic hepatitis, cirrhosis and hepatocellular carcinoma, being the most frequent indication for liver transplantation in several countries. Unfortunately, HCV re-infects the liver graft almost invariably following reperfusion, with an accelerated history of recurrence, leading to 10%-30% of patients progressing to cirrhosis within 5 years of transplantation. In this sense, some groups have even advocated for not re-transplanting this patients, as lower patient and graft outcomes have been reported. However, the management of HCV recurrence is being optimized and several strategies to reduce post-transplant recurrence could improve outcomes, decrease the rate of re-transplantation and optimize the use of available grafts. Three moments may be the focus of potential actions in order to decrease the impact of viral recurrence: the pre-transplant moment, the transplant environment and the post-transplant management. In the pre-transplant setting, it is not well established if reducing the pre transplant viral load affects the risk for HCV progression after transplant. Obviously, antiviral treatment can render the patient HCV RNA negative post transplant but the long-term benefit has not yet been fully established to justify the cost and clinical risk. In the transplant moment, factors as donor age, cold ischemia time, graft steatosis and ischemia/reperfusion injury may lead to a higher and more aggressive viral recurrence. After the transplant, discussion about immunosuppression and the moment to start the treatment (prophylactic, pre-emptive or once-confirmed) together with new antiviral drugs are of interest. This review aims to help clinicians have a global overview of post-transplant HCV recurrence and strategies to reduce its impact on our patients.

    ABSTRACT: The optimal allocation of organs in liver transplantation is a problem that can be resolved using machine-learning techniques. Classical methods of allocation included the assignment of an organ to the first patient on the waiting list without taking into account the characteristics of the donor and/or recipient. In this study, characteristics of the donor, recipient and transplant organ were used to determine graft survival. We utilised a dataset of liver transplants collected by eleven Spanish hospitals that provides data on the survival of patients three months after their operations.

    ABSTRACT: OBJECTIVE: To identify peri-transplant predictors of early graft survival and post-transplant parameters to predict early graft outcome after paediatric liver transplantation (LT). BACKGROUND: Children's response to liver dysfunction after LT is poor. No data have been reported regarding early predictors of poor graft survival that would be of potential value in rescuing children at risk after LT. METHODS: A retrospective, cohort study of 422 paediatric LT performed from 2000-2010 in a single center was conducted. Multiple peri-transplant variables were analyzed. Univariate and multivariate analyses with ROC curves were performed to identify predictors of early (30-, 60-, and 90-days) graft loss (EGL). The number of patients needed to treat (NNT) was calculated when risk factors were identified. Comparisons with Olthoff criteria of early-graft-dysfunction in adults were performed. RESULTS: Overall 30-, 60-, and 90-days graft survival was 93.6%, 92.6% and 90.7%, respectively. Recipient age (0-2 and 6-16 years), acute liver failure (ALF) and post-transplant day-7-serum bilirubin >200 µmol/L were risk factors of graft loss in the three-strata Cox-models. The product of peak-AST, day-2-INR and day-7-bilirubin (30-, 60-, and 90-days AUROCs of 0.77, 0.75 and 0.71) and Day-7-bilirubin levels >200 µmol/L (30-, 60-, and 90-days AUROCs of 0.75, 0.66 and 0.63) had excellent rates of prediction of EGL in the paediatric population (Sensitivity=72.7%; Specificity=96.6%; Positive-predictive-value=95.5%; Negative-predictive-value=78%). The NNT with early re-transplantation when Day-7-bilirubin is >200 µmol/L would be 2.17 (non-adjusted) and 2.76 (adjusted to graft survival). CONCLUSIONS: Two scores have been identified (Peak AST*Day-2-INR*Day-7-Bilirubin and/or post-transplant day-7 bilirubin >200 µmol/L) as clinically valuable tools with high accuracy to predict EGL. A more aggressive attitude to considering early re-transplantation in this group may further improve survival after LT. Liver Transpl, 2012. © 2012 AASLD.

    ABSTRACT: Liver transplant outcomes keep improving, with refinements of surgical technique, immunosuppression and post-transplant care. However, these excellent results and the limited number of organs available have led to an increasing number of potential recipients with end-stage liver disease worldwide. Deaths on waiting lists have led liver transplant teams maximize every organ offered and used in terms of pre and post-transplant benefit. Donor-recipient (D-R) matching could be defined as the technique to check D-R pairs adequately associated by the presence of the constituents of some patterns from donor and patient variables. D-R matching has been strongly analysed and policies in donor allocation have tried to maximize organ utilization whilst still protecting individual interests. However, D-R matching has been written through trial and error and the development of each new score has been followed by strong discrepancies and controversies. Current allocation systems are based on isolated or combined donor or recipient characteristics. This review intends to analyze current knowledge about D-R matching methods, focusing on three main categories: patient-based policies, donor-based policies and combined donor–recipient systems. All of them lay on three mainstays that support three different concepts of D-R matching: prioritarianism (favouring the worst-off), utilitarianism (maximising total benefit) and social benefit (cost-effectiveness). All of them, with their pros and cons, offer an exciting controversial topic to be discussed. All of them together define D-R matching today, turning into myth what we considered a reality in the past.
