Abstract
Model for Endstage Liver Disease (MELD) score has been used to allocate organs since February 2002. This policy allocates organs to candidates with regard to severity of their underlying liver disease except in the case of hepatocellular carcinoma (HCC) patients. The purpose of this study was to determine the impact of MELD on waiting times, dropout rates, and transplantation rates in all patients awaiting liver transplantation at our center. The records of all patients listed for liver transplantation between May 28, 1999, and February 27, 2004, at the Mayo Clinic, Scottsdale, Arizona, were reviewed. Candidates were grouped by two time periods as pre-MELD or post-MELD based on date of MELD implementation (February 27, 2002). The incidence of deceased donor liver transplantation (DDLT), waiting time to DDLT, dropout rate from the waiting list because of clinical deterioration or death, and survival while waiting for or after DDLT were determined for each group. Three hundred fifty-one patients were listed for liver transplantation (195 pre-MELD, 156 post-MELD) during the study period. HCC patients had an improved rate of transplantation after MELD (pre-MELD, 1.39 persons per year; post-MELD, 3.48 persons per year). In all groups, with the exception of hepatitis C virus, the transplantation rates were the same for both categories. The hepatitis C virus group also had improved transplantation rates in the post-MELD period. HCC candidates under the new allocation policy have an increased incidence of DDLT in our institution. However, this has not disadvantaged patients with non-HCC diagnoses. Thus, the new MELD-based allocation policy has benefited all candidates by allowing more timely transplants.

Abstract
PURPOSE OF REVIEW Recent attention in liver transplantation has focused on equity in organ allocation and management of post-transplant complications. RECENT FINDINGS Adoption of the model for end-stage liver disease (MELD) for liver allocation has been successful in implementing a system based on medical urgency rather than waiting time. Refinements are being studied in reducing geographic disparities and improving transplant benefit by balancing pre-transplant mortality and post-transplant survival. With hepatocellular carcinoma becoming a bigger proportion of liver transplants since MELD, emerging literature is examining expansion of the current criteria for transplantation of hepatocellular carcinoma. Hepatitis C virus infection is associated with worse patient and graft survival post-transplantation than other liver diseases. The optimal timing and delivery of current antiviral therapy and immunosuppressive strategies in reducing the severity of hepatitis C virus recurrence post-transplantation are discussed. Chronic renal dysfunction after liver transplantation is a source of considerable morbidity. Nephron-sparing immunosuppression regimens are emerging with encouraging results. SUMMARY Organ allocation tends to evolve under MELD with a focus on reducing geographic disparities and maximizing transplant benefit. Hepatitis C virus, hepatocellular carcinoma and chronic renal dysfunction are a major challenge and continued research in these areas will undoubtedly lead to better outcomes for transplant recipients.

Abstract
BACKGROUND Policies to decrease dropout during waiting time for liver transplantation (LT) are under debate. METHODS We evaluated the allocation system from 1996 to 2003, when recipients had priority related to Child-Pugh score and donors >60 years were mainly offered to recipients with hepatocellular carcinoma (HCC). The outcomes of 656 patients with chronic liver disease (142 HCC and 514 non-HCC) listed for LT were prospectively evaluated, considering recipient and donor features. RESULTS Transplantation and dropout rates were similar between HCC and non-HCC patients: 64.1% vs. 70.6% and 26% vs. 22.6%. Multivariate analysis showed the probability of being transplanted within 3 months was related to Child-Pugh score >10 and to HCC, whereas the probability of being removed from the list within 3 months was only related to Child-Pugh score >10. HCC patients had a lower median waiting time (97 vs. 197 days, P<0.001), a higher rate of donors > 60 years (50.5% vs. 33.5%, P<0.005) and with steatosis (31.6% vs. 14.3%, P<0.01), but a lower Child-Pugh score (9.1+/-2.1 vs. 9.6+/-1.7, P<0.05) than non-HCC patients. The 5-year patient survival was comparable since registration on the list and since LT: 56.9% and 77% in the HCC group vs. 61.4% and 79% in the non-HCC patients. Donors > 60 years affected outcome after LT in the non-HCC group, but not in the HCC patients. CONCLUSION By allocating donors >60 years mainly to HCC patients, we controlled dropout without affecting their survival and the outcome of non-HCC patients.

Abstract
The potential for disease progression in patients awaiting liver transplantation for hepatocellular carcinoma (HCC) has encouraged many centers to employ pre-transplant radiofrequency ablation or chemoembolization in an attempt to control tumor burden while patients are on the wait list. Despite general acceptance by the transplant community, few objective data demonstrate pre-transplant treatment efficacy or improved post-transplant outcomes in HCC patients listed with Model for End-Stage Liver Disease (MELD) exception points. To evaluate the utility of pre-transplant therapy in the current MELD era, we retrospectively compared 31 treated patients (T) with 33 untreated (U) controls. Study endpoints included patient and disease-free survival, tumor recurrence, explant tumor viability, and the ability of MRI to detect viable tumor after therapy. Both cohorts had similar demographic, radiographic, and pathologic characteristics, although untreated patients waited longer for transplantation [119 (U) vs. 54 (T) days after MELD assignment, (P = .05); range: 1 day to 21 months]. Only 20% of treated tumors demonstrated complete ablation (necrosis) as defined by histologic examination of the entire lesion. Only 55% of lesions with histologic viable tumor were detected by MRI after pre-transplant therapy. After 36 months of follow-up, there was no difference between the treated and untreated groups in overall survival (84 vs. 91%), disease free survival (74% vs. 85%), cancer recurrence (23% vs. 12%), or mortality from cancer recurrence (57% vs. 25%) (P > 0.1). In conclusion, viable tumor frequently persists after pre-transplant locoregional therapy, and neoadjuvant treatment does not appear to improve post-transplant outcomes in the current MELD era.

Abstract
BACKGROUND/PURPOSE The role of living-donor liver transplantation (LDLT) in the surgical treatment of patients with hepatocellular carcinoma (HCC) has not been established as yet. METHODS Preliminary experience gained from 24 patients who underwent LDLT for HCC between March 2002 and November 2004, and the results of the 131 patients who underwent hepatic resection (HR) for HCC between January 1990 and December 2003 were retrospectively analyzed. The exclusion criteria for LDLT for HCC included extrahepatic metastasis and major vascular invasion. RESULTS (1) LDLT: the median age of the patients was 57 years and the Child-Pugh grades (A/B/C) of the patients were 6, 12, and 6, respectively. The tumor size was 3 cm or less in 15 patients, multinodular tumors were present in 23 patients, and 11 patients (45.8%) met the Milan Criteria. The overall 2-year survival rate was 72.3%, without a significant difference as to whether or not patients met the Milan criteria. (2) HR: on multivariate analysis, the Child-Pugh grade, the presence of cirrhosis, and the number of tumor nodules were considered as independent risk factors for unfavorable survival (P < 0.05). The 84 patients who met the Milan criteria and were Child-Pugh grade A had a 5-year survival rate of 71.3%; this was significantly better than those of the other patients (P < 0.005). Among the 57 patients with intrahepatic recurrence, 18 patients who were Child-Pugh grade A, met the Milan criteria, and were treated by re-resection or ablation therapy achieved a significantly better 5-year survival rate, of 73.1%, as compared to 19.7% in the other 39 patients (P < 0.0045). CONCLUSIONS HR could be a first-line treatment with a favorable prognosis for patients who have resectable HCC, preserved liver function, and who meet the Milan criteria. Salvage LDLT could be employed in patients with recurrent tumors that cannot be controlled by conventional treatment or in patients in whom liver function has deteriorated to Child-Pugh grade B or C.

Abstract
In patients with hepatocellular carcinoma (HCC) exceeding conventional (T2) criteria for orthotopic liver transplantation (OLT), the feasibility and outcome following loco-regional therapy intended for tumor downstaging to meet T2 criteria for OLT are unknown. In this first prospective study on downstaging of HCC prior to OLT, the eligibility criteria for enrollment into a downstaging protocol included 1 lesion >5 cm and < or =8 cm, 2 or 3 lesions at least 1 >3 cm but < or =5 cm with total tumor diameter of < or =8 cm, or 4 or 5 nodules all < or =3 cm with total tumor diameter < or =8 cm. Patients were eligible for living-donor liver transplantation (LDLT) if tumors were downstaged to within proposed University of California, San Francisco (UCSF) criteria.13 A minimum follow-up period of 3 months after downstaging was required before cadaveric OLT or LDLT, with imaging studies meeting criteria for successful downstaging. Among the 30 patients enrolled, 21 (70%) met criteria for successful downstaging, including 16 (53%) who had subsequently received OLT (2 with LDLT), and 9 patients (30%) were classified as treatment failures. In the explant of 16 patients who underwent OLT, 7 had complete tumor necrosis, 7 met T2 criteria, but 2 exceeded T2 criteria. No HCC recurrence was observed after a median follow-up of 16 months after OLT. The Kaplan-Meier intention-to-treat survival was 89.3 and 81.8% at 1 and 2 yr, respectively. In conclusion, successful tumor downstaging can be achieved in the majority of carefully selected patients, but longer follow-up is needed to further access the risk of HCC recurrence after OLT.

Abstract
PURPOSE The optimal embolic agent for transhepatic arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) has not been identified. This study reports outcomes of TACE for HCC with Gelfoam powder and polyvinyl alcohol (PVA). MATERIALS AND METHODS Eighty-one patients underwent 152 TACE sessions with Gelfoam powder (n = 41) or polyvinyl alcohol (PVA) and Ethiodol (n = 40) as the embolic agent. Chemotherapeutic drugs were the same for all patients (50 mg cisplatin, 20 mg doxorubicin, 10 mg mitomycin-c). The groups were compared based on number of TACE sessions, maximum tumor size, bilirubin level, aspartate and alanine aminotransferase levels, Child-Pugh score, Model for End-stage Liver Disease score, and hepatitis B or C virus positivity. The number of cases of each Child class in each group was also evaluated. Survival starting from the first TACE session was calculated according to Kaplan-Meier analysis. Forty-eight patients died during the study period, 19 received transplants, and 14 were alive at the end of the study period. RESULTS The groups were statistically similar in all categories regarding liver function, Child-Pugh score, tumor size, hepatitis status, and percentage of patients with Child class A, B, and C disease. The number of TACE sessions was significantly greater for the Gelfoam powder group (mean, 2.2) versus the PVA group (mean, 1.6; P = .01). Overall survival was similar between groups whether patients who received transplants were included in the analysis (mean, 659 days +/- 83 with Gelfoam powder vs 565 days +/- 71 with PVA; P = .42) or were excluded (mean, 519 days +/- 80 with Gelfoam powder vs 511 days +/- 75 with PVA; P = .93). CONCLUSION In similar patient groups, survival after treatment of HCC with TACE with Gelfoam powder or PVA and Ethiodol was similar.

Abstract
In the past, organ allocation in the US was based on anecdotal experience, self-interest and the opinions of single centers, with little support in the way of scientific evidence, mathematical survival modeling or validation. As organ transplantation became more successful, and as disparity between the number of patients on the waiting list and available organs became larger, a more justifiable donor allocation scheme became necessary. The current allocation scheme for donor livers is based on the model for end-stage liver disease/pediatric end-stage liver disease, which was introduced in 2002 by the United Network for Organ Sharing. This new allocation system has improved accuracy for predicting pretransplant mortality. In addition, the number of liver transplantations has risen for almost all etiologic categories, most noticeably for patients with hepatocellular carcinoma. Fewer patients have been registered on the liver transplant waiting list and fewer have been removed from the list because they have died or become too sick for transplantation. So far, this new allocation system has been a success, but it does have its shortcomings, and even with improvements to the system, the use of the donor organ pool still needs to be optimized.

Abstract
Prior to therapy, model for end stage liver disease (MELD) scoring, diagnostic imaging and tumor staging were performed in a patient with T3 HCC. The patient received an orthotopic liver transplant (OLT) 42 days after treatment. The explant specimen showed complete necrosis of the target tumor. Follow-up of this patient has demonstrated no evidence of recurrence. There was no life threatening or fatal adverse experiences related to treatment. This case report documents the natural course, history and outcome of a patient treated with yttrium-90 for unresectable HCC. The patient was downstaged from T3 to T2 and was subsequently transplanted.

Abstract
AIMS Recently, there is a tendency to expand tumour sizes qualifying for OLT. The present study re-evaluates tumour size and histopathological features as selection criteria for OLT. METHODS Retrospective analysis of 93 adult HCC patients underwent OLT between June 1985 and December 2003. Median follow-up was 28 months (1-222 months). The Milan criteria were routinely applied since 1994. RESULTS Five year survival rate of HCC patients was significantly lower than in patients transplanted for benign diseases, 41 and 71%, respectively (p<0.0001). Multivariate analysis revealed that the presence of vascular invasion represents the most significant predictor (p<0.001) affecting the survival rate. Survival was also significantly impaired when the tumour size was >5 cm (p<0.05), whereas the number of nodules had no significant effect on survival. Consequently, the survival rate for HCC fulfilling the Milan criteria histologically improved to 70% since 1994. CONCLUSION Tumour size has been shown to be the most important pre-operatively detectable predictor for patient survival after OLT.

Abstract
INTRODUCTION The Model for End-Stage Liver Disease (MELD) has been found to accurately predict pre-transplant mortality and is a valuable system for ranking patients in need of liver transplantation. Its association with post-transplant outcome, however, remains unclear. MATERIALS AND METHODS We retrospectively studied 121 adult patients who were transplanted for non-fulminant liver failure between January 1991 and December 2001. MELD scores were calculated taking variables as close as possible prior to liver transplantation. Patients were stratified into two or three groups using different cut-off values of the MELD score. RESULTS Indications for liver transplantation were mainly alcoholic liver disease (47.1%) or hepatitis C virus (19.0%). Gender distribution was male 62% vs female 38%. Mean age was 54 years+/-10 years. Mean MELD score was 16+/-6. Follow-up time was 5.4 years (range, 1.6-12.3 years). The use of different MELD cut-off levels yielded no difference in survival at different time points. CONCLUSION Higher MELD scores did not have a negative impact on patient and graft survival following OLT. Since MELD is good at identifying those urgently in need of liver transplantation and high MELD scores do not appear to have an influence on long-term outcome, use of MELD in liver allocation seems warranted.

Abstract
In a prospective study, we examined the impact of arterial hypervascularity, as established by the European Association for the Study of the Liver (EASL) recommendations, as a criterion for characterizing small (1-3 cm) nodules in cirrhosis. A total of 72 nodules (1-2 cm, n = 41; 2.1-3 cm, n = 31) detected by ultrasonography in 59 patients with cirrhosis were included in the study. When coincidental arterial hypervascularity was detected at contrast perfusional ultrasonography and helical computed tomography, the lesion was considered to be hepatocellular carcinoma (HCC) according to EASL criteria. When one or both techniques showed negative results, ultrasound-guided biopsy was performed. In cases with negative results for malignancy or high-grade dysplasia, biopsy was repeated when an increase in size was detected at the 3-month follow-up examination. Coincidental hypervascularity was found in 44 of 72 nodules (61%; 44% of 1-2-cm nodules and 84% of 2-3-cm nodules). Fourteen nodules (19.4%) had negative results with both techniques (hypovascular nodules). Biopsy showed HCC in 5 hypovascular nodules and in 11 of 14 nodules with hypervascularity using only one technique. All nodules larger than 2 cm finally resulted to be HCC. Not satisfying the EASL imaging criteria for diagnosis were 38% of HCCs 1 to 2 cm (17% hypovascular) and 16% of those 2 to 3 cm (none hypovascular). In conclusion, the noninvasive EASL criteria for diagnosis of HCC are satisfied in only 61% of small nodules in cirrhosis; thus, biopsy frequently is required in this setting. Relying on imaging techniques in nodules of 1 to 2 cm would miss the diagnosis of HCC in up to 38% of cases. Any nodule larger than 2 cm should be regarded as highly suspicious for HCC.

Abstract
PURPOSE OF REVIEW Liver transplantation continues to change as we further define appropriate criteria for allocation and utilization of this scarce resource. The following review highlights new trends and ideas in this evolving field. RECENT FINDINGS Although the model for end-stage renal disease (MELD) scoring system appears to fairly accurately predict mortality while waiting for transplant, the system may be less accurate in predicting outcomes following transplantation. MELD scores offer an additional advantage to patients with hepatocellular carcinoma (HCC), bringing them to transplant sooner with overall better survivals. However, despite its advantages, the MELD scoring system does not resolve the disparity in the allocation of organs between various organ procurement organizations. Several variables appear to affect patients with hepatitis C undergoing liver transplantation. Selection of appropriate donors appears to be important when transplanting patients with hepatitis C virus (HCV) infection as increasing donor age is associated with poorer outcomes. However, the controversy over whether a living donor liver transplant (LDLT) results in poorer outcomes in HCV infected patients remains. Post-transplant medical treatment of HCV may result in both a sustained virologic response and improved histology. With improved overall survival in patients undergoing orthotopic liver transplant (OLT), increasing attention has been focused on the medical complications following transplant. Identifying specific contributing factors in the development of renal dysfunction and devising strategies to prevent its occurrence are critical to further improvements in outcome following OLT. SUMMARY As the gap between patients and available organs remains, continued investigation into appropriate allocation and maximization of outcomes following liver transplant will continue.

Abstract
Hepatocellular carcinoma (HCC) is a major health problem worldwide, involving more than a half million new cases yearly, with an age-adjusted incidence of 5.5 to 14.9 per 10(5) population. In some areas of Asia and the Middle East, HCC ranks as the first cause of death due to cancer. The incidence of HCC is increasing in Europe and the United States, and it is currently the leading cause of death among cirrhotic patients. It is estimated that by the year 2010, the number of patients with HCC awaiting liver transplant in the United States will outnumber the supply of cadaver organs.

Abstract
As the number of pre- and post-transplant solid organ recipients continues to grow, it becomes important for all physicians to have an understanding of the process of organ procurement and allocation. In the United States, the current system for allocation and transplantation of human solid organs has been heavily influenced by the experience in deceased donor liver transplantation (DDLT). This review highlights the significant changes that have occurred over the past 10 years in DDLT, with specific attention to the impact of the Model for Endstage Liver Disease (MELD) score on organ allocation and pre- and post-transplant survival. DDLT is managed by the United Network for Organ Sharing (UNOS) which oversees organ procurement and allocation across geographically defined Organ Procurement Organizations (OPOs). For many years, deceased donor livers were allocated to waiting list patients based on subjective parameters of disease severity and accrued waiting time. In addition, organs have traditionally been retained within the OPO where they are procured contributing to geographic disparities in disease severity at the time of transplantation among deceased donor recipients. In response to a perceived unfairness in organ allocation, Congress issued its "Final Rule" in 1998. The Rule called for a more objective ranking of waiting list patients and more parity in disease severity among transplant recipients across OPOs. To date, little progress has been made in eliminating geographic inequities. Patients in the smallest OPOs continue to receive liver transplants at a lower level of disease severity. However, strides have been made to standardize assessments of disease severity and better prioritize waiting list patients. The MELD score has emerged as an excellent predictor of short-term mortality in patients with advanced liver disease, and patients listed for liver transplantation are now ranked based on their respective MELD scores. This has improved organ access to the most severely ill patients without compromising waiting list mortality or post-transplant survival. The current system for DDLT remains imperfect but has improved significantly in the past decade. As the number of patients in need of DDLT grows, the system will continue to evolve to meet this increasing demand.

Abstract
Adult-to-adult living donor liver transplantation (ALDLT) is being increasingly utilized to treat patients with locally advanced hepatocellular carcinoma and cholangiocarcinoma who are not prioritized under the MELD allocation system. A single institution retrospective chart review examined ALDLTs performed for malignancy to identify indications, complications, and transplant outcome. Since 1997, 18 ALDLTs have been performed for malignancy as the primary indication. Thirteen patients were transplanted for HCC. The median survival following transplant was 18.6 months and four patients developed recurrent HCC. Five patients were transplanted for cholangiocarcinoma, with a 100% recurrence free survival at a mean follow up of 18 months among patients given neo-adjuvant chemoradiation. ALDLT can be safely performed for malignancy with an acceptable peri-operative mortality rate. However, HCC patients with large tumors experience a high rate of recurrence. The use of ALDLT for cholangiocarcinoma appears promising specifically in the context of neo-adjuvant therapy.

Abstract
Much information has been gained in the diagnosis and treatment of HCC during the last 15 years. Ever improving imaging technology has made nonhistologic diagnostic criteria possible, albeit controversial. Liver transplantation, resection, and RFA are considered curative options. Yet, HCC incidence is steadily rising because of limited progress on disease prevention. Accurate and cost-effective screening is necessary. Presently, only 10% to 15% of HCC patients present with a curative stage of disease. Because the field of HCC is rapidly changing, patients with HCC should be referred to liver centers with a full array of services, from surgical to oncologic. The prognosis for HCC patients will surely improve with a multi-disciplinary approach to care and further clinical research. Better screening and prevention of recurrence should eventually improve survival. It is hoped that antiviral treatment studies will lower the risk of HCC, and that these changes will occur soon enough to help the many patients at risk for or diagnosed with HCC over the next several years.

Abstract
In the United States, cirrhotic patients with known or suspected hepatocellular carcinoma (HCC) are prioritized for liver transplantation. Noninvasive criteria for the diagnosis of HCC rely on arterial enhancement of a mass. The aim of this study was to determine whether clinical, laboratory, and / or radiologic data can improve the prediction of HCC in cirrhotic patients with an arterially-enhancing mass. Between May 2002 and June 2003, dynamic gadolinium-enhanced magnetic resonance imaging (MRI) of consecutive patients with liver cirrhosis and a solid mass were reviewed by 2 radiologists blinded to the clinical diagnosis. Clinical, laboratory, and radiologic data were recorded for all patients. A total of 94 patients with cirrhosis and an arterially-enhancing liver mass were studied, 66 (70%) of whom had HCC. Alpha-fetoprotein (AFP) >20 ng/mL (P = .029), tumor size >2 cm (P = .0018), and delayed hypointensity (P = .0001) were independent predictors of HCC. Delayed hypointensity of an arterially-enhancing mass had a sensitivity of 89% and a specificity of 96% for HCC. The presence of delayed hypointensity was the only independent predictor of HCC among patients with arterially-enhancing lesions <2 cm (odds ratio, 6.3; 95% confidence interval [CI], 1.8-13), with a sensitivity of 80% and a specificity of 95%. In conclusion, delayed hypointensity of an arterially-enhancing mass was the strongest independent predictor of HCC, regardless of the size of the lesion. If additional studies confirm our results, the noninvasive criteria utilized to make a diagnosis of HCC should be revised.

Abstract
Liver transplantation represents an established therapeutic option for advanced liver diseases. The spectrum of indications encompasses infectious, vascular, immunological and toxic diseases leading to cirrhosis, in addition to genetic, metabolic, developmental and selected neoplastic diseases. On the one hand the timing of liver transplantation is determined by the disease specific course until decompensation and the disease manifestation involving bile ducts or hepatocytes. On the other hand it represents gene therapy of diseases affecting the liver, or entities where the genetic defect lies in the liver. In view of the shortage of donor organs and an increasing requirement for liver transplantation the challenge is to provide an effective and fair waiting list management. Reform of allocation criteria has put the focus on urgency. This in turn leads to an increase in waiting time for elective transplantations, inclusion of end stage diseases and critical patients, higher perioperative costs, problems with the matching of organs and the problem of an effective use of organ resources. Fair allocation and medical necessity therefore define the challenges surrounding the indications for liver transplantation.

Abstract
BACKGROUND & AIMS HCV-related cirrhosis is a leading risk factor for hepatocellular carcinoma (HCC). Surveillance might detect HCC at a treatable stage. We estimated the clinical and economic consequences of a common HCC surveillance strategy in patients with HCV-related cirrhosis in the context of alternative HCC treatment strategies. METHODS With a Markov model, we examined surveillance with serum alpha-fetoprotein and ultrasound every 6 months in patients with compensated HCV-related cirrhosis from age 45-70 years or death, and HCC treatment with resection, cadaveric liver transplantation (CLT), or living donor liver transplantation (LDLT). RESULTS Compared to natural history in the base case, surveillance with resection, listing for CLT, or LDLT increased life expectancy by 0.49, 2.58, and 3.81 quality-adjusted life-years (QALYs), respectively, all at costs less than 51,000 US dollars/QALY gained. The consequences of surveillance were most sensitive to the outcomes and costs of HCC treatments but not surveillance test performance characteristics or cost. Prioritizing CLT for patients with HCC over those with decompensated cirrhosis resulted in greater overall life expectancy with minimal increase in cost. CONCLUSIONS Surveillance for HCC in patients with compensated HCV-related cirrhosis might gain QALYs at acceptable costs. The impact of surveillance depends most on the outcomes and costs of HCC treatments, rather than surveillance test characteristics. By increasing organ availability for timely definitive treatment, LDLT might achieve the greatest gain in life expectancy at acceptable costs. Prioritizing CLT for HCC might increase the population-wide benefits of CLT.

Abstract
Recent reports suggest that selected patients undergoing liver transplantation for stage 1-2 hepatocellular cancer (HCC) have an excellent long-term survival and a low incidence of recurrence. In the past, over 45% of HCC patients on the United Network for Organ Sharing/Organ Procurement Transplantation Network waiting list did not receive a donor organ for up to 2 years. This resulted in not only a high mortality rate but a high rate of being removed from the waiting list because of progression of HCC to advanced stages. The introduction of the Model for End-Stage Liver Disease (MELD) allocation policy has had a positive effect on HCC liver transplant candidates with the number of patients transplanted for HCC significantly increasing over the past several years. In addition, waiting time for HCC patients to receive a deceased donor has decreased significantly and the number of patients dropping out from the waiting list because of advanced stage disease has also decreased. An early assessment of the MELD allocation policy suggests that posttransplant survival for HCC patients comparing pre-MELD to post-MELD eras is similar. Using the data we have collected on the MELD allocation policy, we have already made modifications to the MELD allocation policy for HCC patients. It is hoped that through continued data collection and assessment, a consensus can be reached to further optimize the use of deceased donors in HCC recipients.

Abstract
1. Liver transplantation is the main option for patients with early HCC who are not optimal candidates for surgical resection. 2. Shortage of donors is its main limitation, as waiting for a liver allows the tumor to progress and induce exclusion from the waiting list and death. 3. The absence of randomized controlled trials hinders the establishment of the most effective therapy to prevent tumor progression while waiting. 4. Live donation may be a cost-effective approach if optimal results are expected and the mortality risk for the donor is kept below .3%. 5. Priority policies have to be developed and refined to provide a fair and effective distribution of cadaveric organs.

Abstract
OBJECTIVE We sought to determine the outcome of living donor liver transplantation (LDLTx) in 316 adult patients with hepatocellular carcinoma (HCC). SUMMARY BACKGROUND DATA LDLTx has increasingly been performed worldwide, but the impact of the procedure on HCC has not been evaluated in a large series. METHODS Between October 1989 and December 2003, 1389 adults underwent LDLTx at 49 centers in Japan. In 316 (22.8%) who received LDLTx for HCC (70 females, 22%, median age 57 years; and 246 males, 88%, median age, 54 years), we analyzed pretransplant clinical status, imaging diagnosis, transplant procedure, pathologic study of explanted liver, and outcome. In 232 patients (73.4%), various surgical and nonsurgical therapies had been employed prior to LDLTx. The median follow-up period was 16 months (range, 2.5-72.0) RESULTS Currently, 236 (74.7%) of the patients are living. One- and 3-year patient survivals were 78.1% and 69.0%, respectively. Model end-stage liver disease score and preoperative serum alpha-fetoprotein level were independent risk factors for patient survival. Forty patients (12.7%) developed HCC recurrence. Alpha-fetoprotein level, tumor size, vascular invasion, and bilobar distribution were independent risk factors for HCC recurrence. Grade of histologic differentiation of HCC showed close correlation with tumor characteristics and recurrence. One- and 3-year recurrence-free survivals were 72.7% and 64.7%, respectively. When the Milan criteria were applied, patient survival and disease-free survival at 3 years were 78.7% and 79.1%, respectively, in patients who met the criteria, and 60.4% and 52.6%, respectively, in those who did not. CONCLUSION LDLTx can achieve acceptable survival in HCC patients, even when liver function is markedly impaired, or HCC is uncontrollable by conventional antitumor treatments.

Abstract
We retrospectively analyzed all listed patients having hepatic artery chemoembolization (HACE) for hepatocellular carcinoma (HCC) stage T2 or less. Outcomes were transplantation, waiting list removal, death, and HCC recurrence. Twenty patients (mean age 55.7 years; 15 males) were identified. Twelve (60%) were transplanted, seven (35%) were removed from the list and one (5%) remains listed. Fourteen (70%) are alive. All 12 transplanted patients are alive (mean 2.94 years); one of seven removed from the list is alive (mean 1.45 years). Survival was significantly higher for those transplanted or listed vs. removed from the list (100% vs. 14.3%, p = 0.0002). No HCC's recurred. Three patients (15%) were removed from the list after prolonged waiting times before MELD. Hepatic artery chemoembolization induced deterioration and removal from the list of one (5%) patient. Survival for those transplanted was excellent(100%), but overall survival was significantly lower (61.3%) at a mean 5.48 years. Hepatic artery chemoembolization for listed patients with <or=euro T2 stage HCC is beneficial, but must be weighed against decreased waiting times and risk of HACE-induced deterioration. This balance is influenced greatly by the MELD system's determination of waiting times for HCC patients.
