Abstract
BACKGROUND & AIMS The microvascular invasion of cancer cells (mvi) is a good prognostic factor after hepatic resection (HR) and liver transplantation for hepatocellular carcinoma (HCC). This study aimed to predict mvi in patients with HCC. METHODS We studied 63 hepatectomized patients with HCC who had HCC without any extrahepatic metastases and vascular invasion, which were detected during preoperative evaluation. The preoperative clinicopathological data of these patients were analysed to predict presence of mvi. A scoring system was designed using significant risk factors. This system was applied to another series of 34 patients with HCC who underwent HR, and was evaluated for validation. RESULTS Tumour size, serum des-gamma-carboxy prothrombin (DCP) levels and the maximum standardized uptake value (SUVmax) on 2-[18F]-fluoro-2-deoxy-D-glucose positron emission tomography were independent clinical predictors for mvi after multivariate analyses. Tumour size, serum DCP levels, and values of SUVmax were used to plot a receiver operating characteristic curve for predicting mvi. Areas under the curve of tumour size, serum DCP levels and SUV max values, were 0.8652, 0.8027 and 0.7848 respectively. Maximal sensitivity and specificity were obtained when the tumour size was 3.6 cm, SUVmax was 4.2, and the serum DCP level was 101 mAU/ml. A scoring system was designed using these three variables. The sensitivity and specificity of our scoring system were 100% and 90.9%, respectively, in the validation test. CONCLUSION Our scoring system for mvi, consisting of tumour size, serum DCP levels, and SUV max, provides a precise prediction of mvi.

Abstract
BACKGROUND/AIMS The most commonly used immunosuppressant therapy after liver transplantation (LT) is a combination of tacrolimus and steroid. Basiliximab induction has recently been introduced; however, the most appropriate immunosuppression for hepatocellular carcinoma (HCC) patients after LT is still debated. METHODS Ninety-three LT recipients with HCC who took tacrolimus and steroids as major immunosuppressants were included. Induction with basiliximab was implemented in 43 patients (46.2%). Mycophenolate mofetil (MMF) was added to reduce the tacrolimus dosage (n=28, 30.1%). The 1-year tacrolimus exposure level was 7.2 ± 1.3 ng/mL (mean ± SD). RESULTS The 1- and 3-year recurrence rates of HCC were 12.9% and 19.4%, respectively. Tacrolimus exposure, cumulative steroid dosages, and MMF dosages had no impact on HCC recurrence. Induction therapy with basiliximab, high alpha fetoprotein (AFP; >400 ng/mL) and protein induced by vitamin K absence/antagonist-II (PIVKA-II; >100 mAU/mL) levels, and microvascular invasion were significant risk factors for 1-year recurrence (P<0.05). High AFP and PIVKA-II levels, and positive (18)fluoro-2-deoxy-d-glucose positron-emission tomography findings were significantly associated with 3-year recurrence (P<0.05). CONCLUSIONS Induction therapy with basiliximab, a strong immunosuppressant, may have a negative impact with respect to early HCC recurrence (i.e., within 1 year) in high-risk patients.

Abstract
Liver transplantation (LT) for hepatocellular carcinoma (HCC) within Milan criteria is a widely accepted optimal therapy. Neo-adjuvant therapy before transplantation has been used as a bridging therapy to prevent dropout during the waiting period and as a down-staging method for the patient with intermediate HCC to qualify for liver transplantation. Transarterial chemoembolization and radiofrequency ablation are the most commonly used method for locoregional therapy. The data associated with newer modalities including drug-eluting beads, radioembolization with Y90, stereotactic radiation therapy and sorafenib will be discussed as a tool for converting advanced HCC to LT candidates. The concept “ablate and wait” has gained the popularity where mandated observation period after neo-adjuvant therapy allows for tumor biology to become apparent, thus has been recommended after down-staging. The role of neo-adjuvant therapy with conjunction of “ablate and wait” in living donor liver transplantation for intermediate stage HCC is also discussed in the paper.

Abstract
BACKGROUND Liver transplantation has become an established treatment for cirrhotic patients with hepatocellular carcinoma (HCC), and the Milan criteria are now widely accepted and applied as an indication for deceased donor liver transplantation (DDLT) in Western countries. In contrast, however, due to the severe organ shortage, living donor liver transplantation (LDLT) is mainstream in Japan and in other Asian countries. SUMMARY Unlike DDLT, LDLT is not limited by the restrictions imposed by the nationwide allocation system, and the indication for LDLT in patients with HCC often depends on institutional or case-by-case considerations, balancing the burden on the donor, the operative risk, and the overall survival benefit for the recipient. Accumulating data from a nationwide survey as well as individual center experience indicate that extending the Milan criteria is warranted. KEY MESSAGES While the promotion of DDLT should be intensified in Japan and other Asian countries, LDLT will continue to be a mainstay for the treatment of HCC in cirrhotic patients.

Abstract
The implementation of the Milan criteria (MC) in 1996 has dramatically improved prognosis after liver transplantation (LT) in patients with hepatocellular carcinoma (HCC). Liver transplantation has, thereby, become the standard therapy for patients with "early-stage" HCC on liver cirrhosis. The MC were consequently adopted by United Network of Organ Sharing (UNOS) and Eurotransplant for prioritization of patients with HCC. Recent advancements in the knowledge about tumor biology, radiographic imaging techniques, locoregional interventional treatments, and immunosuppressive medications have raised a critical discussion, if the MC might be too restrictive and unjustified keeping away many patients from potentially curative LT. Numerous transplant groups have, therefore, increasingly focussed on a stepwise expansion of selection criteria, mainly based on tumor macromorphology, such as size and number of HCC nodules. Against the background of a dramatic shortage of donor organs, however, simple expansion of tumor macromorphology may not be appropriate to create a safe extended criteria system. In contrast, rather the implementation of reliable prognostic parameters of tumor biology into selection process prior to LT is mandatory. Furthermore, a multidisciplinary approach of pre-, peri-, and posttransplant modulating of the tumor and/or the patient has to be established for improving prognosis in this special subset of patients.

Abstract
Tumor markers [alpha-fetoprotein (AFP) or des-gamma-carboxyprothrombin (DCP)] and neutrophil/lymphocyte ratio (NLR) reportedly correlate with long-term outcomes for hepatocellular carcinoma (HCC). However, no standardized method has been established for evaluating the pretransplant data. One hundred and twenty-four patients who underwent living donor liver transplantation (LDLT) were retrospectively reviewed. The best predictive parameters for tumor recurrence were maximum values for AFP or DCP and 90-day mean values for NLR, respectively, and multivariate analysis confirmed these values were correlated with tumor recurrence. However, receiver operating characteristic analysis revealed that discriminative powers were sufficient only in maximum AFP [area under the curve (AUC) 0.88, P < 0.001] and maximum DCP (AUC 0.76, P < 0.001), while mean NLR was less predictive (AUC 0.62, P = 0.20). When incorporating AFP and DCP to the Tokyo criteria (≤5 tumors with each tumor ≤ 5 cm), the presence of at least two of the following factors: (i) beyond the Tokyo criteria, (ii) AFP>250 ng/ml, and (iii) DCP > 450 mAu/ml (>450 ng/ml), was correlated with a worse 5-year disease-free survival rate (20.0% vs. 96.8%, P < 0.001) and 5-year overall survival rate (20.0% vs. 84.0%, P < 0.001). The prognosis of patients undergoing LDLT for HCC strongly relies on maximum AFP or DCP values before transplantation, while the prognostic impact of NLR is limited.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) <2 cm in diameter has a favorable prognosis. Therefore surgical resection of small HCC is associated with good outcomes. However, the predisposing factors of prognosis following resection of HCC remain ill-defined. The aims of the present study were to identify the clinicopathologic characteristics and outcomes of patients with small HCC and analyze the predisposing factors for tumor recurrence after surgery. METHODS We retrospectively reviewed 180 patients with small HCC who underwent hepatectomy between 2006 and 2010. Independent predictors of tumor recurrence were identified with Cox regression analysis. RESULTS The 1-year, 3-year, and 5-year disease-free survival rates and overall survival rates were 83.7, 68.0, 65.3, and 98.9, 96.5, 92.7 %, respectively. Multivariate analysis reported that protein induced by the vitamin K antagonist-II (PIVKA-II) ≥ 200 mAU/mL, alkaline phosphatase (ALP) ≥ 80 IU/mL, and microvascular invasion were important predisposing factors for tumor recurrence. Elevated serum PIVKA-II level was associated with microvascular invasion in small HCC, which was a powerful predisposing factor. CONCLUSIONS Although small HCC is generally associated with a good prognosis, serum PIVKA-II level ≥ 200 mAU/mL, ALP ≥ 80 IU/L, and microvascular invasion were predisposing factors for tumor recurrence. These factors can be used to stratify patients with respect to recurrence after resection. Elevated PIVKA-II was closely associated with microvascular invasion in small HCC. These data emphasize the importance of PIVKA-II in small HCC.

Abstract
BACKGROUND Previously, we proposed expanded selection criteria for liver transplantation (LT) for hepatocellular carcinoma (HCC), the Kyoto criteria, involving a combination of tumor number ≤10, maximal diameter of each tumor ≤5 cm, and serum des-gamma-carboxy prothrombin levels ≤400 mAU/mL, and we have used these criteria since January 2007. In the present study, the usefulness of the criteria was validated prospectively as well as retrospectively. METHODS One hundred ninety-eight patients with HCC who underwent living donor LT (LDLT) from February 1999 through December 2011 were enrolled in this study. Overall survival and recurrence rates were investigated in patients classified according to the Kyoto criteria, the Milan criteria, or previous treatments for HCC. Tumor biological aggressiveness, including microvascular invasion and histologic differentiation, according to selection criteria was also examined. RESULTS The 5-year overall survival for patients within the Kyoto criteria (n = 147; 82%) was greater than that for the 49 patients exceeding them (n = 49; 42%; P < .001). The 5-year recurrence rate for patients within the Kyoto criteria (4.4%) was less than that for patients exceeding them (51%; P < .001). Intention-to-treat analysis of the 62 patients who underwent LDLT after implementation of the Kyoto criteria showed that the 5-year overall survival rate and the recurrence rate were 82% and 7%, respectively. Tumor biology was significantly less aggressive in patients within the Kyoto criteria. CONCLUSION The Kyoto criteria are useful expanded criteria for LDLT for HCC and could help to achieve favorable outcomes.

Abstract
Zinc-fingers and homeoboxes 2 (ZHX2) and zinc-finger and BTB domain containing 20 (ZBTB20) repress the postnatal expression of α-fetoprotein (AFP) by interacting with the AFP gene promoter regions. ZHX2 inhibits the expression of AFP and cyclins A and E. ZBTB20 is negatively regulated by CUX1, which promotes cell-cycle progression, suggesting that AFP reactivation is closely linked to hepatocyte proliferation. A slight elevation in the serum AFP level often occurs in patients with chronic hepatitis C in the absence of hepatocellular carcinoma (HCC) and is an independent risk factor for HCC development to complement the fibrosis stage. In addition, the sustained elevation of AFP after interferon therapy is a risk factor of HCC development. AFP levels are clinically useful in predicting the outcomes of liver transplantation and sorafenib therapy for HCC patients. A low preoperative AFP level is a predictor of long-term survival and is associated with a low recurrence rate of HCC after liver transplantation. AFP response (≥20% decrease in AFP during 6-8 weeks of treatment) rather than radiological outcomes is a significant prognostic factor for survival in sorafenib-treated HCC patients. Highly sensitive Lens culinaris agglutinin-reactive AFP (AFP-L3) is 5-10 times more sensitive than conventional AFP-L3, and useful for early detection of HCC in patients with total AFP below 20 ng/mL.

Abstract
The first human liver transplant operation was performed by Thomas Starzl in 1963. The next two decades were marked by difficulties with donor organ quality, recipient selection, operative and perioperative management, immunosuppression and infectious complications. Advances in each of these areas transformed liver transplantation from an experimental procedure to a standard treatment for end-stage liver disease and certain cancers. From the handful of pioneering programmes, liver transplantation has expanded to hundreds of programmes in >80 countries. 1-year patient survival rates have exceeded 80% and outcomes continue to improve. This success has created obstacles. Ongoing challenges of liver transplantation include those concerning donor organ shortages, recipients with more advanced disease at transplant, growing need for retransplantation, toxicities and adverse effects associated with long-term immunosuppression, obesity and NASH epidemics, HCV recurrence and the still inscrutable biology of hepatocellular carcinoma. This Perspectives summarizes this transformation over time and details some of the challenges ahead.

Abstract
We retrospectively investigated the prognostic value of hepatocyte nuclear factor 1 (HNF1) proteins in 159 liver transplant patients with hepatocellular carcinoma (HCC), including 36 (22.6%) exceeding the Milan criteria. The expression of alpha-fetoprotein (AFP), HNF1α, and HNF1β was examined with immunohistochemistry on duplicate tissue microarray slides containing HCC tumor explants. The times to recurrence and cancer death were analyzed with a Cox regression model and were compared according to the expression of markers of interest. We compared risk predictions with area under the receiver operator curves (AUROCs) and C statistics. AFP, HNF1α, and HNF1β were positive in 22.6%, 46.5%, and 61.0% of the tumor immunoprofiles, respectively. Although several variables were associated with the times to recurrence and cancer death in univariate Cox analyses, only AFP expression for the time to recurrence and the Milan criteria and HNF1β expression for the times to recurrence and cancer death remained significant after multivariate adjustments. The expression of HNF1β (but not HNF1α) was related to a serum AFP level ≥ 200 ng/mL, microvascular invasion, and AFP expression (P < 0.05 for all). A subgroup analysis showed that in the group meeting the Milan criteria, recurrence and cancer death rates at 10 years in the HNF1β-negative patients were approximately one-tenth of those in the HNF1β-positive patients, but the difference was not significant in the group exceeding the Milan criteria. The addition of HNF1β expression to the Milan criteria increased the C statistics and AUROCs for both recurrence and mortality (P < 0.05 for all). In conclusion, the immunohistological detection of HNF1β predicts recurrence and HCC-specific death after transplantation and provides an additive benefit in comparison with the Milan selection criteria on their own.

Abstract
Hepatocellular carcinoma (HCC) continues to rise and is still a major cause of mortality. Orthotopic liver transplantation (OLT) continues to give patients the best chance for cure, but recurrence of the disease remains a problem. Even with the implementation of the Milan criteria, recurrence rates have been shown to be 8-15% in most studies and even higher in patients who are beyond the Milan criteria. Therefore, several investigators have looked into the value of adjuvant therapy using systemic cytotoxic chemotherapy in HCC after OLT. Unfortunately, most of the trials are very small, and the results have been disappointing. But trials using Licartin seem to be promising, and other drugs such as FOLFOX and sorafenib warrant further investigation based on their efficacy in the advanced disease. In this review, we will review the current data on efficacy and rationale of adjuvant treatment for HCC after OLT including novel biomarkers.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in some areas of the world. In most cases, HCC is diagnosed at a late stage. Therefore, the prognosis of patients with HCC is generally poor. The recommended screening strategy for patients with cirrhosis includes the determination of serum α-fetoprotein (AFP) levels and an abdominal ultrasound every 6 months to detect HCC at an earlier stage. AFP, however, is a marker characterized by poor sensitivity and specificity, and abdominal ultrasound is highly dependent on the operator's experience. In addition to AFP, Lens culinaris agglutinin-reactive AFP (AFP-L3), des-γ-carboxy prothrombin (DCP), glypican-3 (GPC-3), osteopontin (OPN), and several other biomarkers (such as squamous cell carcinoma antigen-immunoglobulin M complexes [SCCA-IgM], alpha-1-fucosidase [AFU], chromogranin A [CgA], human hepatocyte growth factor, insulin-like growth factor) have been proposed as markers for the early detection of HCC. For these markers, we describe the mechanisms of production, and their diagnostic and prognosis roles. None of them is optimal; however, when used together, their sensitivity in detecting HCC is increased. Recent research has shown that some biomarkers have mitogenic and migratory activities in the angiogenesis of HCC and are a factor of tumor growth.

Abstract
BACKGROUND In liver transplantation or resection for hepatocellular carcinoma (HCC), patient selection depends on morphological features. In patients with HCC, we performed a clinicopathological analysis of risk factors that affected survival after liver transplantation. METHODS In 389 liver transplantations performed from 2004 to 2010, 102 were for HCC patients. Data were collected retrospectively from the Organ Transplantation Center Database. Variables were as follows: age, gender, preoperative alpha-fetoprotein (AFP) levels, Child-Pugh and MELD scores, prognostic staging criteria (Milan and UCSF), etiology, number of tumors, the largest tumor size, total tumor size, multifocality, intrahepatic portal vein tumor thrombosis, bilobarity, and histological differentiation. RESULTS One hundred and two patients were evaluated. The 5-year overall survival rate was 56.5%. According to the UCSF criteria, 63% of the patients were within and 37% were beyond UCSF (P=0.03). Ten patients were excluded (one with fibrolamellary HCC and 9 because of early postoperative death without HCC recurrence), and 92 patients were assessed. The mean age of the patients was 56.5+/-6.9 years. Sixty-two patients underwent living donor liver transplantations. The mean follow-up time was 29.4+/-22.6 months. Fifteen patients (16.3%) died in the follow-up period due to HCC recurrence. Univariate analysis showed that AFP level, intrahepatic portal vein tumor thrombosis, histologic differentiation and UCSF criteria were significant factors related to survival and tumor recurrence.The 5-year estimated overall survival rate was 62.2% in all patients. According to the UCSF criteria, and the 5-year overall survival rate was 66.7% within and 52.7% beyond the criteria (P=0.04). Multivariate analysis showed that AFP level and poor differentiation were independent factors. CONCLUSIONS For proper patient selection in liver transplantation for HCC, prognostic criteria related to tumor biology (especially AFP level and histological differentiation) should be considered. Poor differentiation and higher AFP levels are indicators of poor prognosis after liver transplantation.

Abstract
BACKGROUND Liver transplantation (LT) offers a possible cure for carefully selected patients with hepatocellular carcinoma (HCC). Studies report that preoperative alpha-fetoprotein (AFP) is a prognostic indicator that can predict survival and recurrence in these patients. AIM To undertake a systematic review of available literature on preoperative AFP as a predictor of survival and recurrence following LT for HCC. METHODS A literature search was performed using Medline, Embase, Cochrane Library, CINAHL and Google scholar databases to identify studies reporting AFP as a prognostic marker in LT for HCC. Primary outcomes of interest were overall survival and recurrence. Secondary outcomes were correlation of pre-LT AFP with vascular invasion and grade of tumour differentiation. RESULTS A total of 13 studies met the inclusion criteria (12,159 patients). The majority were male (9603, 78.9%). All were observational studies and only one prospective. Methodological quality was rated as poor for all studies, with selection and observer bias apparent for most cohorts. Reported survival rates and recurrence rates varied widely between the studies although overall demonstrated better outcomes for those with lower (<1000 ng/mL) pre-LT AFP levels. Similarly, rates of vascular invasion and poor tumour differentiation were higher in those with high pre-LT AFP levels. CONCLUSIONS A quantity of AFP >1000 ng/mL is associated with poorer outcomes from liver transplantation for hepatocellular carcinoma. The quality of studies was generally poor and precluded valid statistical meta-analysis. There is a need to improve the performance and reporting of primary prognostic studies to facilitate high quality systematic review and meta-analysis.

Abstract
OBJECTIVES The prognosis in patients with hepatocellular carcinoma (HCC) accompanied by main portal vein tumour thrombus (MPVTT) is poor. The aim of this study was to clarify the factors linked to survival of >5 years after hepatectomy in HCC patients with MPVTT. METHODS Twenty-nine HCC patients with MPVTT were divided into two groups comprising, respectively, patients who survived >5 years after hepatectomy (survivors, n= 5) and those who did not (non-survivors, n= 24). The two groups were compared. RESULTS Overall survival rates at 1, 3 and 5 years were 62.1%, 24.1% and 17.2%, respectively. Four (80.0%) 5-year survivors had recurrences of HCC in which the number of recurrent nodules was under four. Three (21.4%) of the 14 non-survivors who underwent curative resection experienced recurrences of HCC and all of them demonstrated fewer than four recurrent nodules (P= 0.0114). Local therapy, such as radiofrequency ablation and resection of recurrence, had more often been used in survivors than in non-survivors (P= 0.0364). CONCLUSIONS Although surgical outcomes in patients with HCC accompanied by MPVTT are unsatisfactory, some patients do enjoy longterm survival. When the number of recurrent nodules is less than four, local therapy should be selected with the aim of achieving 5-year survival.

Abstract
Hepatocellular carcinoma (HCC) often occurs in patients with chronic liver disease or cirrhosis. Liver transplantation for hepatocellular carcinoma has the potential to eliminate both the tumor as well as the underlying cirrhosis and is the ideal treatment for HCC in cirrhotic liver as well as massive HCC in noncirrhotic liver. Limitations in organ availability, necessitate stringent selection of patients who would likely to derive most benefit. Selection criteria have considered tumor size, number, volume as well as biological features. The Milan criteria set the benchmark for tumors that would benefit from liver transplantation but were found to be excessively restrictive. Modest expansion in criteria has also been shown to be associated with equivalent survival. Microvascular invasion is the single most important adverse prognostic factor for survival. Living donor liver transplantation has expanded donor options and has the advantage of lower waiting period and not impacting the non-HCC waiting list. Acceptable outcomes have been obtained with living donor liver transplantation for larger and more numerous tumors in the absence of microvascular invasion. Downstaging of tumors to prevent progression while waiting for an organ or for reduction in size to allow enrolment for transplantation has met with variable success.

Abstract
OBJECTIVE To determine the importance of the expression pattern of multiple tumor markers for hepatocellular carcinoma (HCC) with regard to the tumor malignancy and patient survival. BACKGROUND Several studies have indicated that HCC tumor markers, including alpha-fetoprotein (AFP), Lens culinaris agglutinin-reactive fraction of AFP and des-γ-carboxy prothrombin were predictors of HCC malignancy. However, few reports have shown the relevance of the expression pattern of these 3 tumor markers with regard to patient prognosis. We herein reported the influence of the expression pattern of these 3 tumor markers on HCC malignancy and patient prognosis. METHODS This retrospective study analyzed 185 patients who underwent hepatectomy for HCC between January 1999 and May 2009. The relationships between clinical parameters and these 3 tumor markers were analyzed. Cox proportional hazards regression analyses were performed to estimate risk factors for recurrence and survival. Furthermore, the relationships between pathological parameters and the expression patterns of the 3 tumor markers were analyzed. RESULTS From clinical parameters, expression patterns of 3 tumor markers were related to maximum tumor size and macrovascular invasion in image findings. Multivariate analyses revealed independent risk factors for recurrence or survival to be the Child-Pugh score, the presence of multiple tumors, and triple positive tumor marker expression. From pathological findings, microvascular invasion and an Edmondson-Steiner classification of III or IV were related to the expression patterns of the 3 tumor markers. CONCLUSIONS Triple positive tumor markers for HCC showed poor prognosis and invasive characteristics in pathological findings. Examination of these markers would be useful for predicting the degree of HCC malignancy.

Alpha-fetoprotein and novel tumor biomarkers as predictors of hepatocellular carcinoma recurrence after surgery: a brilliant star raises again. Int J Hepatol 2012; 2012:893103.

Abstract
Alpha-fetoprotein (AFP), des-γ-carboxy prothrombin (DCP), and lens culinaris agglutinin-reactive fraction of AFP (AFP-L3) have been developed with the intent to detect hepatocellular carcinoma (HCC) and for the surveillance of at-risk patients. However, at present, none of these tests can be recommended to survey cirrhotic patients at risk for HCC development because of their suboptimal ability for routine clinical practice in HCC diagnosis. Starting from these considerations, these markers have been therefore routinely and successfully used as predictors of survival and HCC recurrence in patients treated with curative intent. All these markers have been largely used as predictors in patients treated with hepatic resection or locoregional therapies, mainly in Eastern countries. In recent studies, AFP has been proposed as predictor of recurrence after liver transplantation and as selector of patients in the waiting list. Use of AFP modification during the waiting list for LT is still under investigation, potentially representing a very interesting tool for patient selection. The development of a new predictive model combining radiological and biological features based on biological markers is strongly required. New genetic markers are continuously discovered, but they are not already fully available in the clinical practice.

Abstract
Although liver transplantation is a widely accepted treatment for hepatocellular carcinoma (HCC), much controversy remains and there is no generally accepted set of guidelines. An international consensus conference was held on Dec 2-4, 2010, in Zurich, Switzerland, with the aim of reviewing current practice regarding liver transplantation in patients with HCC and to develop internationally accepted statements and guidelines. The format of the conference was based on the Danish model. 19 working groups of experts prepared evidence-based reviews according to the Oxford classification, and drafted recommendations answering 19 specific questions. An independent jury of nine members was appointed to review these submissions and make final recommendations, after debates with the experts and audience at the conference. This report presents the final 37 statements and recommendations, covering assessment of candidates for liver transplantation, criteria for listing in cirrhotic and non-cirrhotic patients, role of tumour downstaging, management of patients on the waiting list, role of living donation, and post-transplant management.

Abstract
AIM Although hepatocellular carcinoma (HCC)-specific serum tumor markers, α-fetoprotein (AFP) and des-γ-carboxy prothrombin (DCP), are used in the screening for HCC, their utility in pre-transplantation evaluation is not well established. This study aimed to evaluate the accuracy of AFP and DCP measurement for the diagnosis of HCC in liver transplant candidates. METHODS A total of 315 consecutive adult patients (174 men and 141 women, mean age 52 years), who were to receive liver transplantation for end-stage liver diseases, were enrolled. The pre-transplant levels of AFP and DCP were compared with the histopathology of explanted liver. RESULTS Hepatocellular carcinoma was present in the explanted liver of 106 recipients (median number of nodules 2, mean diameter 2.5 cm). The area under receiver operating characteristic curve for the diagnosis of HCC was 0.83 (95% confidence interval, 0.78-0.88) for AFP and 0.47 (0.41-0.54) for DCP. With the cut-off value of 100 mAU/mL, 20/106 (18.9%) patients with HCC and 54/194 (27.8%) patients without HCC were positive for DCP. DCP positivity was associated with vascular invasion, tumor differentiation and size among patients with HCC, which was associated with albumin level among patients without HCC. Vitamin K was administered prior to transplantation to 20 patients who were positive for DCP (two with and 18 without HCC), resulting in a decrease in DCP levels in 19 of them. CONCLUSIONS Serum DCP levels may be raised in end-stage liver disease patients without HCC, and cannot be used as a reliable marker for HCC among liver transplant candidates.

Abstract
Background Recurrence prediction of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) patients undergoing liver transplantation (LT) present a great challenge because of a lack of biomarkers. Genetic variations play an important role in tumor development and metastasis. Methods Oligonucleotide microarrays were used to evaluate the genetic characteristics of tumor DNA in 30 HBV-related HCC patients who were underwent LT. Recurrence-related single-nucleotide polymorphism were selected, and their prognostic value was assessed and validated in two independent cohorts of HCC patients (N = 102 and N = 77), using pretransplant plasma circulating DNA. Prognostic significance was assessed by Kaplan-Meier survival estimates and log-rank tests. Multivariate analyses were performed to evaluate prognosis-related factors. Results rs894151 and rs12438080 were significantly associated with recurrence (P = .003 and P = .004, respectively). Multivariate analyses demonstrated that the co-index of the 2 SNPs was an independent prognostic factor for recurrence (P = .040). Similar results were obtained in the third cohort (N = 77). Furthermore, for HCC patients (all the 3 cohorts) exceeding Milan criteria, the co-index was a prognostic factor for recurrence and survival (P<.001 and P = .002, respectively). Conclusions Our study demonstrated first that genetic variations of rs894151 and rs12438080 in pretransplant plasma circulating DNA are promising prognostic markers for tumor recurrence in HCC patients undergoing LT and identify a subgroup of patients who, despite having HCC exceeding Milan criteria, have a low risk of post-transplant recurrence.

Abstract
Because of its increasing incidence of hepatocellular carcinoma, it is now recognized as a worldwide health problem affecting mostly patients with chronic liver disease. Liver transplantation is the optimal therapy and achieves its best results in patients with small tumour burden. In an effort to prevent tumour progression and patient dropout from the transplant wait list, the concept and utilization of neo-adjuvant locoregional therapies have gained relevance in the past few years. Moreover, good and maintained response to therapy is now considered a surrogate of favourable tumour biology, therefore aiding the patient transplant selection process. Herein, we review the current role of neo-adjuvant therapies and revise concepts of tumour 'downstaging' or 'bridging therapy' in the setting of liver transplantation. In addition, we explore the debate of implementing locoregional therapy for patients with small tumours and short waiting times to liver transplantation.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is a heterogeneous malignancy with multiple etiologies, high incidence, and high mortality. The standard surgical management for patients with HCC consists of locoregional ablation, surgical resection, or liver transplantation, depending on the background state of the liver. Eighty percent of patients initially presenting with HCC are unresectable, either due to the extent of tumor or the level of underlying hepatic dysfunction. While in patients with no evidence of cirrhosis and good hepatic function resection has been the surgical treatment of choice, it is contraindicated in patients with moderate to severe cirrhosis. Liver transplantation is the optimal surgical treatment. DATA SOURCES PubMed search of recent articles (from January 2000 to March 2011) was performed looking for relevant articles about hepatocellular carcinoma and its treatment. Additional articles were identified by evaluating references from selected articles. RESULTS Here we review criteria for transplantation, the types, indications, and role of locoregional therapy in treating the cancer and in downstaging for possible later transplantation. We also summarize the contribution of immunosuppression and adjuvant chemotherapy in the management and prevention of HCC recurrence. Finally we discuss recent advances in imaging, tumor biology, and genomics as we delineate the remaining challenges for the diagnosis and treatment of this disease. CONCLUSIONS Much can be improved in the diagnosis and treatment of HCC. A great challenge will be to improve patient selection to criteria based on tumor biology. Another will be to incorporate systemic agents post-operatively in patients at high risk for recurrence, paying close attention to efficacy and safety. The future direction of the effort in treating HCC will be to stimulate prospective trials, develop molecular imaging of lymphovascular invasion, to improve recipient selection, and to investigate biomarkers of tumor biology.

Abstract
PURPOSE DCP is a useful HCC tumor marker, which reflects a defect in vitamin K metabolism. We tested the hypothesis that vitamin K treatment of HCC patients might suppress this marker and possibly AFP also. EXPERIMENTAL DESIGN HCC patients who had both elevated AFP and DCP were included. A phase I cohort was treated with escalating vitamin K1 intravenous weekly doses and a 27-patient phase II cohort was then treated with a fixed oral daily dose. RESULTS A maximum tolerated dose was not reached up to 100-fold the normal vitamin K1 dose. No toxicities were found up to 1,000 mg/infusion. In the phase II cohort, 93% of patients had tumor marker responses by decreased DCP levels, but only 22% had responses by decreased AFP levels. CT scans showed 11% of patients had PRs, 59% had stable tumors and 29.6% had tumor progression. Mechanism studies showed that vitamin K1 induced phosphorylation of JNK and c-Jun and caspase-mediated apoptosis. CONCLUSIONS Vitamin K1 was non-toxic at high doses, strongly inhibited plasma DCP levels, but weakly suppressed AFP levels. The results provide evidence that the two tumor markers are not directly linked and that DCP levels may not reflect HCC cell growth, as DCP levels were decreased in patients without AFP change, and were suppressed in vitro at 1% of the vitamin K1 concentration needed to inhibit AFP.

Abstract
Hepatocellular carcinoma (HCC) shows a high rate of recurrence after hepatectomy; predictive factors for early recurrence would help determine optimal therapeutic and management strategies. Among 163 patients with HCC undergoing hepatectomy with curative intent, 46 patients developed recurrence within 1 year. Clinicopathological data were retrospectively analyzed to identify predictive parameters for early recurrence. Survival rates in cases of recurrence within 1 year were worse than those of no recurrence within 1 year or recurrence after 1 year. Protein induced by vitamin K absence/antagonist II (PIVKA-II) greater than 150, positive fucosylated alpha-fetoprotein (L3-AFP), and deviancy from Milan criteria (MC) on preoperative imaging were associated with high risk of early recurrence and total number of these three risk factors predicted the survival. With multivariate analysis, 1) preoperatively, positive factors of two or more among three items of PIVKA-II, L3-AFP, and deviancy from MC; 2) and postoperatively, pathological cancer spread (microscopic vascular invasion and/or intrahepatic metastasis) both represented risks for early recurrence. A combination of three preoperative factors, PIVKA-II, L3-AFP, and MC status, in conjunction with the postoperative factor of cancer spread status represents a significant indicator for recurrence within 1 year. Improving the prognosis of patients with HCC would depend on how to adequately treat those at high risk of early recurrence.

Abstract
Des-γ-carboxyprothrombin (DCP) is known as a tumour marker for hepatocellular carcinoma (HCC). Various tumour markers have been developed for serological diagnosis of cancers, including HCC, in order to increase the survival rate of cancer patients. The currently recommended combined testing of DCP and α-fetoprotein (AFP) or Lens culinaris agglutinin-reactive fraction of α-fetoprotein has been established to diagnose HCC. This combined testing using several tumour markers helps to increase the sensitivity of diagnosis of HCC, thus significantly increasing the clinical usefulness of DCP. The excessive production of DCP may be related to worse tumour behaviour, such as the presence of vascular invasion and intrahepatic metastasis of HCC cells. A high level of DCP was suggested to be useful as one of the factors in new recipient selection criteria of liver transplantation. The clinical use of DCP, therefore, might play a vital role in predicting tumour behaviour in patients with HCC. That said, the basic mechanism of DCP production has not been fully clarified. Various factors such as vitamin K(2) and γ-glutamyl carboxylase may contribute to the production of DCP and have a complex relationship. Moreover, recent studies have revealed that DCP functions as a growth factor and might play significant roles in cancer progression. Thus, DCP represents a potential target of drug discovery to establish new chemotherapeutic strategy for HCC. However, various issues have to be resolved to construct a novel therapy for HCC-targeting DCP. Innovation is required to make further progress in examining DCP.

Improved results of a surgical resection for the recurrence of hepatocellular carcinoma after living donor liver transplantation. Ann Surg Oncol 2010; 17:2283-9.

Abstract
PURPOSE This study was designed to analyze the clinical outcomes of the recurrence of hepatocellular carcinoma (HCC) after living donor liver transplantation (LDLT) and to evaluate the efficacy of a surgical resection in treating such a recurrence. METHODS A total of 101 adult LDLT recipients with HCC between 1996 and 2007, including 17 who had recurrent HCC, were reviewed. The endpoints analyzed were survival from time of transplant and survival from time of recurrence. Recipient demographics, laboratory valuables, and tumor characteristics were analyzed. Any medical or surgical treatments that had been administered for any recurrence also were considered. RESULTS The mean duration until the initial recurrence after LDLT and the mean duration until death after the initial recurrence were 12.9 months and 12.0 months, respectively. A univariate analysis showed that gender, interferon therapy, early posttransplant tumor recurrence, and eligibility for a surgical resection all had a beneficial impact on survival from tumor recurrence. A surgical resection of tumor relapse was the most important variable in our study, and therefore the patients were divided into two groups: surgical therapy group (n = 9), and nonsurgical therapy group (n = 7). Interestingly, the overall survival rates of the surgical group were significantly better than those of the nonsurgical group and were similar to that of the patients without HCC recurrence. CONCLUSIONS Surgical therapy might be useful for patients who experience a recurrence of HCC after LDLT to improve their outcome, when such treatment is available.
