Hepatocellular carcinoma: Can it be considered a controversial indication for liver transplantation in centers with high rates of hepatitis C?

Resection vs Transplant Listing for Hepatocellular Carcinoma: An Intention-to-Treat Analysis

BACKGROUND

Liver transplantation (LT) and liver resection (LR) are curative treatment options for patients with hepatocellular carcinoma within the Milan criteria. Severe organ shortage dictates the preference for LR. Our aim was to provide an intention-to-treat retrospective comparison of survival between patients who were placed on waiting lists for LT and those who underwent LR.

METHODS

The medical records of patients with hepatocellular carcinoma within the Milan criteria treated by LR or listed for LT between 2007 and 2016 were reviewed. We performed intention-to-treat analyses of overall survival and recurrence.

RESULTS

There were 54 patients on the waiting list for LT, and 30 of them underwent LR. Thirteen of the 54 patients (24%) were not transplanted because of disease-related mortality or tumor progression. The median waiting time to transplantation was 304 days. The 90-day mortality was higher in transplanted patients (9.8% vs 3.3%, P = .003). Intention-to-treat survival was similar for the LT and LR groups (5-year survival, 47.8% vs 55%, respectively, P = .185). There was a trend toward improved 5-year disease-free survival for listed patients (56.2% vs 26.3% for patients undergoing LR, P = .15).

CONCLUSION

Intention-to-treat survival is similar in patients undergoing LR and those on waiting lists for LT. There is a 24% risk to drop from the transplant list. The higher perioperative mortality among patients undergoing LT is balanced by a higher tumor recurrence rate after LR.

High serum caspase-3 levels in hepatocellular carcinoma prior to liver transplantation and high mortality risk during the first year after liver transplantation

Background: Higher liver caspase-3 activity has been found in patients with different liver diseases. However, there is no published data about circulating caspase-3 levels in patients with hepatocellular carcinoma (HCC) who underwent liver transplantation (LT). Therefore, our objective in this study was to determine whether an association between circulating caspase-3 levels in HCC patients prior to LT and one-year mortality after LT exists. Methods: In this observational and retrospective study, we included HCC patients who underwent LT. We measured serum levels of caspase-3 (as the main executor of apoptosis) and caspase-cleaved cytokeratin (CCCK)-18 (to estimate apoptosis degree) before LT. Results: One-year surviving LT patients (n = 129) showed lower serum levels of caspase-3 (p = 0.004) and CCCK-18 (p = 0.001) than non-surviving LT patients (n = 16). Logistic regression analysis showed that serum caspase-3 levels prior to LT were associated with one-year after LT mortality (Odds Ratio = 2.612; 95% CI = 1.519-4.493; p = 0.001). We found a positive association between serum levels of caspase-3 and CCCK-18 (rho = 0.26; p = 0.002). Conclusions: Our study is the first one reporting data of circulating caspase-3 levels prior to LT for HCC, and an association between high serum caspase-3 levels previously to LT and survival at first year after LT.

High serum soluble CD40L levels previously to liver transplantation in patients with hepatocellular carcinoma are associated with mortality at one year

PURPOSE

CD40L and its soluble form (sCD40L) are proteins of the tumor necrosis factor superfamily (TNFSF) that exhibit prothrombotic and proinflammatory properties when binding to CD40, which is a cell surface receptor of the tumor necrosis factor receptor superfamily (TNFRSF). High circulating levels of sCD40L have been associated with poor prognosis in patients with hepatocellular carcinoma (HCC). However, it is unknown whether there is an association between circulating sCD40L levels and survival in patients with HCC underwent to liver transplantation (LT), and this was the objective of that study.

METHODS

Serum sCD40L levels were measured in a total of 139 patients before LT (124 survivors at 1year of LT and 15 non-survivors). The end-point study was 1year survival after liver LT.

RESULTS

We found that 1-year non-surviving patients showed higher serum sCD40L levels than survivor patients (p=0.02). We found in logistic regression analysis that serum sCD40L levels higher than 321pg/mL (Odds Ratio=6.86; 95% confidence interval=2.06-22.76; p=0.002) and age of LT deceased donor were associated with death at 1year.

CONCLUSIONS

The new finding of our study was that high serum sCD40L levels previously to LT in patients with HCC are associated with higher mortality at one year.

Human immunodeficiency virus-infected liver transplant recipients with incidental hepatocellular carcinoma: A prospective multicenter nationwide cohort study

There is a lack of data on incidental hepatocellular carcinoma (iHCC) in the setting of liver transplantation (LT) in human immunodeficiency virus (HIV)-infected patients. This study aims to describe the frequency, histopathological characteristics, and outcomes of HIV+ LT recipients with iHCC from a Spanish multicenter cohort in comparison with a matched cohort of LT patients without HIV infection. A total of 15 (6%) out of 271 patients with HIV infection who received LT in Spain from 2002 to 2012 and 38 (5%) out of the 811 HIV- counterparts presented iHCC in liver explants (P = 0.58). Patients with iHCC constitute the present study population. All patients also had hepatitis C virus (HCV)-related cirrhosis. There were no significant differences in histopathological features of iHCC between the 2 groups. Most patients showed a small number and size of tumoral nodules, and few patients had satellite nodules, microvascular invasion, or poorly differentiated tumors. After a median follow-up of 49 months, no patient developed hepatocellular carcinoma (HCC) recurrence after LT. HIV+ LT recipients tended to have lower survival than their HIV- counterparts at 1 (73% versus 92%), 3 (67% versus 84%), and 5 years (50% versus 80%; P = 0.06). There was also a trend to a higher frequency of HCV recurrence as a cause of death in the former (33% versus 10%; P = 0.097). In conclusion, among LT recipients for HCV-related cirrhosis, the incidence and histopathological features of iHCC in HIV+ and HIV- patients were similar. However, post-LT survival was lower in HIV+ patients probably because of a more aggressive HCV recurrence. Liver Transplantation 23 645-651 2017 AASLD.

Prognostic Value of Serum Caspase-Cleaved Cytokeratin-18 Levels before Liver Transplantation for One-Year Survival of Patients with Hepatocellular Carcinoma

Cytokeratin (CK)-18 is the major intermediate filament protein in the liver and during hepatocyte apoptosis is cleaved by the action of caspases; the resulting fragments are released into the blood as caspase-cleaved cytokeratin (CCCK)-18. Higher circulating levels of CCCK-18 have been found in patients with hepatocellular carcinoma (HCC) than in healthy controls and than in cirrhotic patients. However, it is unknown whether serum CCCK-18 levels before liver transplantation (LT) in patients with HCC could be used as a prognostic biomarker of one-year survival, and this was the objective of our study with 135 patients. At one year after LT, non-survivors showed higher serum CCCK-18 levels than survivors (p = 0.001). On binary logistic regression analysis, serum CCCK-18 levels >384 U/L were associated with death at one year (odds ratio = 19.801; 95% confidence interval = 5.301–73.972; p < 0.001) after controlling for deceased donor age. The area under the receiver operating characteristic (ROC) curve of serum CCCK-18 levels to predict death at one year was 77% (95% CI = 69%–84%; p < 0.001). The new finding of our study was that serum levels of CCCK-18 before LT in patients with HCC could be used as prognostic biomarker of survival.

Outcome of liver transplantation in patients with hereditary bleeding disorders: a single centre UK experience

INTRODUCTION

Patients with hereditary bleeding disorders who have developed end-stage liver disease as a consequence of hepatitis C infection (HCV) acquired from factor concentrates prior to the introduction of viral inactivation continue to be referred for liver transplantation.

METHODS

A retrospective review of case notes and electronic records was performed on all patients with bleeding disorders who have undergone liver transplantation at the University Hospital Birmingham (UHB).

RESULTS

Between 1990 and 2014, 35 liver transplants have been performed in 33 patients with hereditary bleeding disorders. The indication for transplantation was mainly end-stage liver disease secondary to HCV. Five patients had human immunodeficiency virus (HIV) co-infection. No excess mortality due to bleeding occurred in the peri or postoperative period. Median overall survival post transplant is 9.7 years. Overall survival rates at 1, 3 and 5 years are 90%, 72% and 64% respectively. The predominant cause of mortality was liver failure secondary to either recurrent HCV or recurrent hepatocellular carcinoma (HCC). The median overall survival in patients with HIV co-infection is shorter than in those with mono-infection but this is not statistically significant. Patients with a pre-existing HCC had a statistically significant shorter survival (2.4 years vs. 13.6 years, P = 0.007).

CONCLUSION

Liver transplantation has become an accepted treatment option for patients with hereditary bleeding disorders and HCV associated end-stage liver disease with survival rates similar to non-bleeding disorder patients.

Outcomes of Patients With Hepatocellular Carcinoma After Liver Transplant

OBJECTIVES

Liver transplant is one of the few effective treatments for hepatocellular carcinoma. Our aim in this study was to evaluate the risk factors for hepatocellular carcinoma recurrence after liver transplant.

MATERIALS AND METHODS

In this retrospective study, conducted between October 1988 and March 2015, four hundred seventy-three liver transplants were performed at our institution. Of these, 231 were pediatric and 242 were adult. Among these patients, liver transplant was performed in 58 patients (12.3%) for treatment of hepatocellular carcinoma.

RESULTS

Hepatocellular carcinoma recurrence was detected in 14 patients (24.1%). Overall 5-year and 10-year survival rates of patients underwent liver transplant beyond the Milan criteria for hepatocellular carcinoma were 50.3% and 43.1%. Overall, 5- and 10-year survival rates of patients underwent liver transplant within the Milan criteria for hepatocellular carcinoma were 78.4% and 72.6%. The main predictive variable was whether the tumor had expensed beyond the Milan criteria.

CONCLUSIONS

As expected, outcomes were significantly better in the Milan criteria group. Although the overall- and disease-free survival rates were promising in such a group of patients who had no better chance, it could be asserted that liver transplant is a safe and effective treatment option with promising results, even if the tumor expanse is beyond the Milan criteria.

Surgical approach for hepatitis C virus-related hepatocellular carcinoma

Hepatitis C is a strong prognostic factor for patients with hepatocellular carcinoma (HCC). Although liver resection and liver transplantation offer the chance of a cure for HCC, adequate management of co-existing infection with hepatitis C virus (HCV) is important to enable better long-term outcomes after surgery for HCV-related HCC. For patients undergoing liver resection, perioperative anti-viral treatment is recommended, since a decreased HCV viral load itself is reportedly associated with a lower tumor recurrence rate and a longer overall survival. For patients undergoing transplanatations for HCC complicated by end-stage liver disease, the post-transplant management of HCV infection is also necessary to prevent progressive graft injury caused by active hepatitis under the immunosuppressive condition that is needed after liver transplantation. Although only a few lines of solid evidence are available for postoperative antiviral treatment because of the limited indication and frequent adverse events caused by conventional high-dose combination interferon therapy, new direct acting anti-viral agents would enable interferon-free anti-viral treatment with a higher virologic response and minimal side effects.

Viral status at the time of liver transplantation for hepatocellular carcinoma: a modern predictor of longterm survival

OBJECTIVES

The impact of pre-transplant hepatitis B virus (HBV) and/or hepatitis C virus (HCV) infection in patients with hepatocellular carcinoma (HCC) is not well described. This study was conducted to test the hypothesis that viral status is an independent predictor of retransplantation rates, graft survival (GS) and overall survival (OS) in patients undergoing liver transplantation for HCC.

METHODS

Patients with HCC were identified from the Organ Procurement and Transplantation Network database (2005-2012), and categorized by viral status according to these categories: HBV-/HCV-; HBV+/HCV-; HBV-/HCV+, and HBV+/HCV+.

RESULTS

Of 7742 patients transplanted for HCC, 7060 had known HBV and HCV status. Five-year GS and OS were highest in recipients who were HBV+/HCV-, at 75% and 78%, respectively, compared with patients who were HBV-/HCV- (GS = 63%, OS = 66%), HBV-/HCV+ (GS = 64%, OS = 60%) or HBV+/HCV+ (GS = 60%, OS = 62%). In multivariable analyses, HBV-/HCV+ patients were more likely than HBV+/HCV- patients to undergo repeat transplantation. Patients who were HBV-/HCV+ also had poorer GS and OS than both HBV-/HCV- and HBV+/HCV- patients. Other independent predictors of poorer OS included older age, higher Model for End-stage Liver Disease score, African-American race, and diabetes. The few HBV+/HCV+ patients (n = 138) showed trends toward fewer retransplantations, prolonged GS and prolonged OS compared with HBV-/HCV+ patients. In adjusted models, antiviral medications did not impact GS or OS.

CONCLUSIONS

In the era of modern selection criteria, viral status is an independent predictor of outcome following liver transplantation for HCC. Both HBV-/HCV- and HBV+/HCV- patients have superior GS and OS compared with HBV-/HCV+ patients.

Hepatitis C infection and hepatocellular carcinoma in liver transplantation: a 20-year experience

BACKGROUND

Hepatitis C infection (HCV) and hepatocellular carcinoma (HCC), the two main causes of liver transplantation (LT), have reduced survival post-LT. The impact of HCV, HCC and their coexistence on post-LT survival were assessed.

METHODOLOGY

All 601 LT patients from 1992 to 2011 were reviewed. Those deceased within 30 days (n = 69) and re-transplants (n = 49) were excluded. Recipients were divided into four groups: (a) HCC-/HCV-(n = 252) (b) HCC+/HCV- (n = 58), (c) HCC-/HCV+ (n = 106) and (d) HCC+/HCV+ (n = 67). Demographics, the donor risk index (DRI), Model for End-Stage Liver Disease (MELD) score, survival, complications and tumour characteristics were collected. Statistical analysis included anova, chi-square, Fisher's exact tests and Cox and Kaplan-Meier for overall survival.

RESULTS

Groups were comparable with regards to baseline characteristics, but HCC patients were older. After adjusting for age, MELD, gender and the donor risk index (DRI), survival was lower in the HCC+/HCV+ group (59.5% at 5 yrs) and the hazard ratio (HR) was 1.90 [95% confidence interval (CI),1.24-2.95, P = 0.003] and 1.45 (95% CI, 0.99-2.12, P = 0.054) for HCC-/HCV+. HCC survival was similar to controls (HR 1.18, 95% CI, 0.71-1.93, P = 0.508). HCC+/HCV- patients exceeded the Milan criteria (50% versus 31%, P < 0.04) and had more micro-vascular invasion (37.5% versus 20.6%, P = 0.042). HCC+/HCV+ versus HCC+/HCV- survival remained lower (HR 1.94, 95% CI, 1.06-3.81, P = 0.041) after correcting for tumour characteristics and treatment.

CONCLUSION

HCV patients had lower survival post-LT. HCC alone had no impact on survival. Patient survival decreased in the HCC+/HCV+ group and this appears to be as a consequence of HCV recurrence.

Liver transplantation and expanded Milan criteria: does it really work?

CONTEXT

Orthotopic liver transplantation is an excellent treatment approach for hepatocellular carcinoma in well-selected candidates. Nowadays some institutions tend to Expand the Milan Criteria including tumor with more than 5 cm and also associate with multiple tumors none larger than 3 cm in order to benefit more patients with the orthotopic liver transplantation.

METHODS

The data collected were based on the online database PubMED. The key words applied on the search were "expanded Milan criteria" limited to the period from 2000 to 2009. We excluded 19 papers due to: irrelevance of the subject, lack of information and incompatibility of the language (English only). We compiled patient survival and tumor recurrence free rate from 1 to 5-years in patients with hepatocellular carcinoma submitted to orthotopic liver transplantation according to expanded the Milan criteria from different centers.

RESULTS

Review compiled data from 23 articles. Fourteen different criteria were found and they are also described in detail, however the University of California - San Francisco was the most studied one among them.

CONCLUSION

Expanded the Milan criteria is a useful attempt for widening the preexistent protocol for patients with hepatocellular carcinoma in waiting-list for orthotopic liver transplantation. However there is no significant difference in patient survival rate and tumor recurrence free rate from those patients that followed the Milan criteria.

Resection or transplant-listing for solitary hepatitis C-associated hepatocellular carcinoma: an intention-to-treat analysis

OBJECTIVES

The relative roles of liver resection (LR) and liver transplantation (LT) in the treatment of a solitary hepatocellular carcinoma (HCC) remain unclear. This study was conducted to provide a retrospective intention-to-treat comparison of these two curative therapies.

METHODS

Records maintained at the study centre for all patients treated with LR or listed for LT for hepatitis C-associated HCC between January 2002 and December 2007 were reviewed. Inclusion criteria required: (i) an initial diagnosis of a solitary HCC lesion measuring ≤ 5 cm, and (ii) Child-Pugh class A or B cirrhosis. The primary endpoint analysed was intention-to-treat survival.

RESULTS

A total of 75 patients were listed for transplant (LT-listed group) and 56 were resected (LR group). Of the 75 LT-listed patients, 23 (30.7%) were never transplanted because they were either removed from the waiting list (n = 13) or died (n = 10). Intention-to-treat median survival was superior in the LR group compared with the LT-listed group (61.8 months vs. 30.6 months), but the difference did not reach significance. Five-year recurrence was higher in the LR group than in the 52 LT patients (71.5% vs. 30.5%; P < 0.001).

CONCLUSIONS

In the context of limited donor organ availability, partial hepatectomy represents an efficacious primary approach in properly selected patients with hepatitis C-associated HCC.

Infection with hepatitis C virus is an adverse prognostic factor after liver resection for early-stage hepatocellular carcinoma: implications for the management of hepatocellular carcinoma eligible for liver transplantation

INTRODUCTION

Recent data support liver resection (LR) as first-line approach in patients with preserved liver function who have resectable/transplantable hepatocellular carcinoma (HCC). This study was designed to evaluate the outcome of LR in patients with transplantable HCC.

METHODS

Between 1998 and 2009, 75 patients (65 men, mean age 61 ± 11 years) with HCC eligible for liver transplantation (LT) underwent LR. The underlying hepatic disease was related to hepatitis C (HCV) in 30 (40 %) patients, hepatitis B (HBV) in 15 (20 %) patients, alcohol abuse in 26 patients (36 %) and other in 10 patients (13 %). Fifty-five (73 %) patients had cirrhosis. Intermittent clamping of the hepatic pedicle was used in 41 (55 %) patients. Treatment of recurrence by salvage LT was performed in 6 (8 %) patients.

RESULTS

Operative morbidity and mortality rates were 37 and 5 % respectively. At 1, 3, and 5 years, overall (OS) and disease-free (DFS) survival rates were 81, 69,55 and 56, 31, and 21 %, respectively. On multivariate analysis, HCV infection was the only independent factor associated with decreased OS (p = 0.02). On multivariate analysis, HCV infection (p = 0.05) and intermittent hepatic pedicle clamping (p = 0.003) were associated with decreased DFS. The 1-, 3-, and 5-year OS and DFS rates in patients with HCV-related HCC were 69, 53, 38 and 50, 18, and 9% respectively.

CONCLUSIONS

Overall and disease-free survival after liver resection in patients with HCV-related HCC and preserved liver function is poor. Primary LT should be offered to these patients.

Spanish society of liver transplantation (SETH) consensus recommendations on hepatitis C virus and liver transplantation

In November 2010, the Spanish Society of Liver Transplantation (Sociedad Española de Trasplante Hepático, SETH) held a consensus conference. One of the topics of debate was liver transplantation in patients with hepatitis C. This document reviews (i) the natural history of post-transplant hepatitis C, (ii) factors associated with post-transplant prognosis in patients with hepatitis C, (iii) the role of immunosuppression in the evolution of recurrent hepatitis C and response to antiviral therapy, (iv) antiviral therapy, both before and after transplantation, (v) follow-up of patients with recurrent hepatitis C and (vi) the role of retransplantation.

Systematic review: the prognostic role of alpha-fetoprotein following liver transplantation for hepatocellular carcinoma

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.

Liver transplantation and hepatitis C

Hepatitis-C-virus- (HCV-) related end-stage cirrhosis is the primary indication for liver transplantation in many countries. Unfortunately, however, HCV is not eliminated by transplantation and graft reinfection is universal, resulting in fibrosis, cirrhosis, and finally graft decompensation. The use of poor quality organs, particularly from older donors, has a highly negative impact on the severity of recurrence and patient/graft survival. Although immunosuppressive regimens have a considerable impact on the outcome, the optimal regimen after liver transplantation for HCV-infected patients remains unclear. Disease progression monitoring with protocol biopsy and new noninvasive methods is essential for predicting patient/graft outcome and starting antiviral treatment with the appropriate timing. Antiviral treatment with pegylated interferon and ribavirin is currently considered the most promising regimen with a sustained viral response rate of around 30% to 35%, although the survival benefit of this regimen remains to be investigated. Living-donor liver transplantation is now widely accepted as an established treatment for HCV cirrhosis and the results are equivalent to those of deceased donor liver transplantation.

Can the dropout risk of candidates with hepatocellular carcinoma predict survival after liver transplantation?

In the last US national conference on liver transplantation for hepatocellular carcinoma (HCC), a continuous priority score, that incorporates model for end-stage liver disease (MELD), alpha-fetoprotein and tumor size, was recommended to ensure a more equitable liver allocation. However, prioritizing highest alpha-fetoprotein levels or largest tumors may select lesions at a higher risk for recurrence; similarly, patients with higher degree of liver failure could have lower postoperative survival. Data from 300 adult HCC recipients were reviewed and the proposed HCC-MELD equation was applied to verify if it can predict post-transplantation survival. The 5-year survival and recurrence rates after transplantation were 72.8 and 13.5%, respectively. Cox regression analysis confirmed HCC-MELD as predictive of both postoperative survival and recurrence (p < 0.001). The 5-year predicted survival and recurrence rates were plotted against the HCC-MELD-based dropout probability: the higher the dropout probability while on waiting list, the lower the predicted survival after transplantation, that is worsened by hepatitis C positivity; similarly, the higher the predicted HCC recurrence rate after transplantation. The HCC priority score could predict the postoperative survival of HCC recipients and could be useful in selecting patients with greater possibilities of survival, resulting in higher post-transplantation survival rates of HCC populations.

Comparison between observed survival after resection of transplantable hepatocellular carcinoma and predicted survival after listing through a Markov model simulation

There is still some debate on whether hepatic resection or liver transplantation should be the initial treatment for hepatocellular carcinoma (HCC) in compensated cirrhosis. Clinical data and observed survivals of 150 transplantable patients (within Milan criteria) resected for HCC were reviewed and their predicted survival after listing for liver transplantation was calculated using a Markov model simulation. Differences between observed and predicted survival estimates were explored by standardized differences (d). The mean observed survival within 5 years after surgery was 45.35 months, and the predicted survival after listing was 49.18 months (d = 0.265). The largest gain in life-expectancy with liver transplantation would be obtained in patients with Model for End-stage Liver Disease (MELD) score >9 (d = 0.403); conversely, observed and predicted survivals were similar in HCV+ patients (d = -0.002) and in patients with MELD ≤9 (d = -0.057). For T1 tumors, the observed mean estimate of survival after hepatic resection was higher than that predicted by the simulation (d = -0.606). In conclusion, in HCV patients and in those with very well compensated cirrhosis, hepatic resection could lead to results similar to those of transplantation strategy for HCC within Milan criteria; HCC T1 patients are probably best served by resection as first-line therapy rather than listing for transplantation.

Liver transplantation for hepatocellular carcinoma: the Baylor experience

BACKGROUND

Liver transplantation (LTX) is indicated in selected patients with hepatocellular carcinoma (HCC) and cirrhosis.

METHODS

We compared the outcome of LTX for patients with and without HCC in 5-year time periods between 1987 and 2007 to reflect the implementation of the Milan tumor selection criteria in 1997 and of the model for end-stage liver disease (MELD) score-based liver allocation in 2002.

RESULTS

Of 2350 patients who underwent primary LTX, 330 had HCC. Five-year patient survival for HCC patients was 28.6% in 1987-1992 and 42.3% in 1992-1997, which was 41.4-31.4% lower than that in non-HCC patients (P < 0.0001). After 1997, 5-year survival was 76% for HCC patients, similar to the survival for non-HCC patients (P = 0.8784). Five-year tumor recurrence dropped from 52.9% (1987-1992) and 48.2% (1992-1997) to 11.4% (1997-2002) and 8.4% (2002-2007) (P < 0.0001). Multivariate analysis for tumor recurrence showed the following significant factors: tumor size >6 cm [hazard ratio (HR) 3.67], >or=5 nodules (HR 3.441), vascular invasion (HR 3.18), transplant in 1987-1992 (HR 6.772), and transplant in 1992-1997 (HR 3.059). MELD-based liver allocation reduced median waiting time for LTX for HCC versus non-HCC (35 vs. 111 days; P = 0.005) without compromise in patient outcome.

CONCLUSIONS

The results of LTX for HCC continue to improve and are equal to results in patients without HCC.

Survival after liver transplantation for hepatocellular carcinoma in the model for end-stage liver disease and pre-model for end-stage liver disease eras and the independent impact of hepatitis C virus

It has been suggested that hepatitis C virus (HCV) patients with hepatocellular carcinoma (HCC) may have worse outcomes after liver transplantation (LT) because of more aggressive tumor biology. In this study, we determined the post-LT survival of HCC patients with and without HCV using United Network for Organ Sharing data from January 1994 to March 2008. Patients with HCC were stratified into HCV (HCC-HCV) and non-HCV (HCC-non-HCV) groups. In the era before the Model for End-Stage Liver Disease (MELD), there were 1237 HCC patients (780, HCV; 373, non-HCV; 84, unknown HCV status), and during the MELD era, there were 4933 HCC patients (3272, HCV; 1348, non-HCV; 313, unknown). In the pre-MELD era, 5-year graft (58.6% versus 53.7%) and patient (61.7% versus 59.3%) survival rates were marginally higher for HCC-non-HCV patients than for HCC-HCV patients. In the MELD era also, 5-year graft (61.2% versus 55.5%) and patient (63.7% versus 58.2%) survival rates were marginally higher for HCC-non-HCV patients than for HCC-HCV patients. In patients without HCC, pre-MELD and MELD era graft/patient survival rates for non-HCV patients were higher than those for HCV patients. The differences in survival rates for HCC patients with and without HCV were lower than those for non-HCC patients stratified by their HCV status. HCV had no additional negative impact on the post-LT survival of patients with HCC, and this was further confirmed by multivariate analysis. In conclusion, the survival of HCC patients has remained unchanged in the past 2 decades. HCV patients have a lower survival rate than non-HCV patients, regardless of their HCC status, but HCV has no additional negative impact on survival in patients with HCC.

Improved results of transplantation for hepatocellular carcinoma: a report from the International Registry of Hepatic Tumors in Liver Transplantation

Improved outcome after liver transplantation (LTX) for hepatocellular carcinoma (HCC) made LTX a legitimate treatment of the disease. We analyzed trends of LTX for HCC with tumors known before transplantation in 902 patients in a large international registry across 3 periods: 1983-1990, 1991-1996, and 1997-2005. Patient survival improved gradually across eras, with 5-year survival rates of 25.3%, 44.4%, and 67.8%, respectively (P < 0.0001), and the 5-year tumor recurrence rate declined from 59% to 41.3% and 15%, respectively (P < 0.0001). The number of HCC nodules and tumor size decreased over time, and there were fewer moderately or poorly differentiated tumors. Tumors > 5 cm decreased from 54.5% to 31.7% and 11.7%, respectively (P < 0.0001), and LTX with >or=4 nodules decreased from 38.9% to 23.5% and 15.1%, respectively (P = 0.0044). Poorly differentiated tumors decreased from 37.2% to 31.8% and 20.3%, respectively (P = 0.0005). Tumor microvascular invasion remained at 21.2% to 23.8% despite changes in patient selection over time (P = 0.7124). Stepwise Cox regression analysis (n = 502) showed significant risk for tumor recurrence and patient survival for transplants before 1997 [hazard ratio (HR), 1.82 and 1.88, respectively], tumor size > 6 cm (HR, 2.09 and 1.76), microvascular invasion (HR, 1.75 and 1.69, respectively), and alpha-fetoprotein > 200 (HR, 2.45 and 2.32, respectively). In conclusion, outcome after LTX for HCC has improved continuously over the past 20 years. Improved perioperative care and better patient selection may partially explain the improved outcome after LTX for HCC.

Poorer survival in patients whose explanted hepatocellular carcinoma (HCC) exceeds Milan or UCSF Criteria. An analysis of liver transplantation in HCC in Australia and New Zealand

BACKGROUND

Milan and University of California San Francisco (UCSF) Criteria have been used for selection of patients with hepatocellular carcinoma (HCC) for liver transplantation (LTx). The aims of this study were to analyse the results of LTx for HCC in Australia and New Zealand with emphasis on the effects of discordance between pre-LTx radiological and post-LTx pathological staging.

METHODS

A total of 186 LTx for HCC carried out between July 1985 and August 2003 were included. Patients were categorized according to the Milan and UCSF Criteria.

RESULTS

The median follow-up was 6.55 years (range 2.96-20.93 years). Pre-LTx factors associated with better survival include tumour size < or = 5 cm, number of tumours < or = 3, staging within Milan and UCSF Criteria and more recent transplantation (1996-2003). In all, 14 patients had a pre-LTx stage outside the Milan but within the UCSF Criteria. One- and 5-year patient survival rates were, respectively, 88% and 74% within the Milan Criteria, and 87% and 73% within the UCSF Criteria. Vascular invasion, capsular invasion, lymph node invasion and pathological stage outside UCSF Criteria were associated with poor outcome. Of patients within the Milan and UCSF Criteria pre-LTx, 24% and 18%, respectively, were outside the same criteria post-LTx. These patients had poorer survival rates.

CONCLUSIONS

The use of the UCSF Criteria in this cohort increased the number of patients eligible for LTx without compromising 5-year survival rates. Patients whose explant tumours were outside the Milan or UCSF Criteria had poorer outcomes compared with those whose explants remained within these criteria.

Expanded criteria for liver transplantation in patients with cirrhosis and hepatocellular carcinoma

Orthotopic liver transplantation (OLT) selection for patients with hepatocellular carcinoma (HCC) is a matter of debate. The Milan criteria (MC) have been largely adopted by the international community. The main aim of this study was to evaluate the survival rates and recurrence probabilities of a new proposal for criteria (up to 3 tumors, each no larger than 5 cm, and a cumulative tumor burden </= 10 cm). Patients with cirrhosis and HCC included on the waiting list (WL) from 1991 to 2006 were retrospectively analyzed. Outcomes in patients who had tumors within and beyond the MC were compared. The survival analysis was done (1) with the intention-to-treat principle and (2) among transplanted patients. A total of 281 patients were included in WL. Twenty-four cases did not undergo OLT (a dropout rate of 8.5%); all but 1 case had tumors within the MC. Of the 257 transplanted patients, 26 had tumors beyond the MC in the pre-OLT evaluation. Based on the intention-to-treat analysis, the 5-year survival was 56% versus 66% in patients who had tumors within and beyond the MC, respectively (P = 0.487). Among transplanted patients, the 5-year survival was 62% versus 69%, respectively (P = 0.734). Through multivariate analysis, microvascular invasion was an independent prognostic factor of poor survival (P = 0.004). The recurrence probabilities at 1 and 5 years were 7% versus 12% and 14% versus 28% in patients with tumors within and beyond the MC, respectively (P = 0.063). The multivariate analysis demonstrated that both poorly differentiated tumors (P < 0.001) and microvascular invasion (P < 0.001) increased the risk of recurrence. The expansion to up to 3 nodules, each up to 5 cm, and a cumulative tumor burden </= 10 cm did not result in a reduction of survival in comparison with patients who had tumors within the MC.

The natural history of recurrent hepatitis C and what influences this

1. Liver failure and liver cancer from chronic hepatitis C are the most common indications for liver transplantation and numbers of both are projected to double over the next 20 years. 2. Recurrent hepatitis C infection of the allograft is universal and immediate following liver transplantation and associated with accelerated progression to cirrhosis, graft loss and death. 3. Graft and patient survival is reduced in liver transplant recipients with recurrent HCV infection compared to HCV-negative recipients. 4. The natural history of chronic hepatitis C is accelerated following liver transplantation compared C, with 20% progressing to cirrhosis by 5 years. However, the rate of fibrosis progression is not uniform and may increase over time. 5. The rates of progression from cirrhosis to decompensation and from decompensation to death are also accelerated following liver transplantation. 6. Multiple host, donor and viral factors are associated with rapid fibrosis progression and HCV-related graft failure. 7. Over the last decade, graft and patient survival rates have improved following liver transplantation for non-HCV disease but not for HCV-cirrhosis. This may reflect worsening donor quality and changes in immunosuppression strategies over recent years. 8. Viral eradication by antiviral therapy prevents disease progression and improves survival. 9. The severity of recurrent hepatitis C at one year post-transplant predicts subsequent progression to cirrhosis. Annual protocol biopsies are recommended to help determine need for antiviral therapy. 10. The projected impact of recurrent hepatitis C on graft and patient survival can only be avoided by the development of safe and effective antiviral strategies which can both prevent initial graft infection and eradicate established hepatitis C recurrence.

[Liver transplant in patients with hepatocellular carcinoma]

Liver transplant in patients with cirrhosis and hepatocellular carcinoma is indicated in the early stages of the disease, which can be achieved with early detection programs using liver ultrasound. Dynamic imaging techniques (ultrasound with contrast, magnetic resonance and tomography) are essential in the diagnosis of this tumour, being able to type the lesion clearly, and, in the majority of cases, lead to the therapy to follow. Surgery is the treatment of choice in these patients, and liver transplant, from a theoretical point of view, is the best. Currently, the size and number of nodes play an important role in the indication of a transplant. The best liver transplant results are obtained in these patients using the Milan criteria, with survivals that exceed 70% and recurrence indices of 15%, at 5 years. Nowadays we have the possibility of using neo-adjuvant treatments to transplant, such as arterial chemoembolisation, percutaneous ablation techniques, and even liver resection as a bridging technique. The survival of patients transplanted due to liver cancer is similar to that obtained for other non-tumour diseases. In Spain it is 1, 3 and 5 years and 82%, 70% and 60%, respectively. The recurrence is between 6.4% and 16%, micro- and macrovascular invasion being its highest risk variable.

Viral hepatitis after liver transplantation

Recurrence of the original liver disease following liver transplantation is a typical complication in viral hepatitis. Recent advances, particularly the development of strategies to prevent or effectively treat hepatitis B, have led to substantial improvements in the post-transplantation outcome of hepatitis B candidates. While the efficacy of antivirals to treatrecurrent hepatitis C has improved in recent years, there is as yet no therapy to universally prevent recurrent infection, and tolerability of antivirals remains a matter of concern.

Survival outcomes in liver transplantation for hepatocellular carcinoma, comparing impact of hepatitis C versus other etiology of cirrhosis

The incidence of hepatocellular carcinoma (HCC) is on the rise worldwide as the most common primary hepatic malignancy. In the US approximately one half of all HCC is related to Hepatitis C virus (HCV) infection. The relationship between the primary disease and HCC recurrence after liver transplantation is unknown. We hypothesized that the primary hepatic disease underlying the development of cirrhosis and HCC would be associated with the risk of recurrent HCC after transplantation. A retrospective review was conducted of all primary liver transplants performed at the University of Rochester Medical Center from May 1995 through June 2004. The pathology reports from the native livers of 727 recipients were examined for the presence of HCC. There were 71 liver transplant recipients with histopathological evidence of HCC. These patients were divided in two groups on the basis of HCV status. Group 1 consisted of 37 patients that were both HCV and HCC positive, and Group 2 consisted of 34 patients that were HCC positive but HCV negative. Patient characteristics were analyzed, as well as number of tumors, tumor size, presence of vascular invasion, lobe involvement, recipient demographics, donor factors, pretransplantation HCC therapy, rejection episodes, and documented HCC recurrence and treatment. There were no statistically significant differences between the 2 groups, with the exception of recipient age and the presence of hepatitis B coinfection. The tumor characteristics of both groups were similar in numbers of tumors, Milan criteria status, vascular invasion, incidental HCC differentiation, and largest tumor size. The HCV positive population had a far lower patient survival rate with patient survival in Group 1 at 1, 3, and 5 years being 81.1%, 57.4%, and 49.3% respectively, compared with 94.1%, 82.8%, and 76.4% in Group 2 (p = 0.049). Tumor-free survival in Group 1 at 1, 3, and 5 years was 70.3%, 43%, and 36.8% respectively, vs. 88.1%, 73%, and 60.8% in Group 2. In a subgroup analysis, tumor-free survival was further examined by stratifying the patients on the basis of Milan criteria. Group 1 patients outside of Milan criteria had a statistically lower tumor-free survival. By contrast, there was no statistical difference in tumor-free survival in Group 2 patients stratified according to Milan criteria. Cox regression analysis identified HCV and vascular invasion as significant independent predictors of tumor-free survival. Our results suggest that Milan selection criteria may be too limiting and lose their predictive power when applied to patients without HCV infection.

Primary hepatocellular cancer in the explanted liver: outcome of transplantation and risk factors for HCC recurrence

AIM

To evaluate the risk of recurrence of hepatocellular cancer (HCC) after liver transplantation (LT).

METHODS

The clinical records of 104 patients with HCC in the explanted liver were examined.

RESULTS

HCC recurrence occurred in 12 patients. Recurrence was observed in all patients with a single nodule greater than 5 cm. Among the 5 patients with more than 3 tumours with a maximum diameter of 4.5 cm, no recurrence occurred. The survival rates were 81% and 64% at 1 and 5 years, respectively; the recurrence-free survival at 1 and 5 years was, respectively, 93% and 82%. Pre-LT alpha-fetoprotein (AFP) increased at a greater magnitude in patients who experienced recurrence, compared to those who did not. Tumour diameter, differentiation, satellitosis, AFP and the magnitude of AFP increase were predictive of recurrence. The 1- and 5-year recurrence-free survival for the 68 patients who had a single nodule up to 5 cm, or up to 3 nodules all less than 4.5 cm and with a maximum cumulative diameter of 8 cm, or more than 3 nodules all less than 2.5 cm, were 95% and 92%, respectively. For the 13 patients not meeting these criteria, the 1- and 5-year recurrence-free survival was, respectively, 75% and 54% (log Rank test p=0.019).

CONCLUSIONS

Patients with more than 3 small HCC nodules before LT could still have a good outcome without recurrence. A rapid increase in AFP could be useful in identifying patients with a greater risk of post-LT HCC recurrence.

Liver transplantation and recurrent hepatocellular carcinoma: predictive value of nodule size in a retrospective and explant study

BACKGROUND

Recurrence of hepatocellular carcinoma (HCC) after liver transplantation (LT) remains a major cause of post-LT death.

METHODS

To assess which preoperative and postoperative variables were related to recurrence of HCC after LT in patients with cirrhosis and HCC, we evaluated 96 patients with cirrhosis (74 with known HCC and 22 with incidental HCC) who survived more than 1 month after LT.

RESULTS

The median waiting list time was 36 days (range 1-370 days), and the median interval from detection to transplant was 180 days (range 14-1460 days). The size of largest nodule on imaging was strongly associated with recurrence (odds ratio 1.03; 95% confidence interval 0.99-1.06; P=0.064) when transplantation was performed for known HCC. Among postoperative variables, only the largest nodule diameter (independently of the number of smaller nodules) was multivariately associated with recurrence (odds ratio 1.05; 95% confidence interval 1.01-1.08; P=0.005). The best predictive cutoff was 35 mm in diameter, based on a receiver operating curve with 1-, 3-, and 5-year recurrence-free survival of 90%, 73%, and 49%, respectively, for patients with a nodule 35 mm in diameter or more compared with 96%, 93%, and 89% (P=0.0005), respectively, for patients with smaller nodules.

CONCLUSIONS

In our cohort with a short waiting list time, only the largest nodule diameter, especially in the explant, predicted recurrence after LT independently of the number of nodules. New proposals for increasing the diameter of the largest nodule as a selection criteria for LT do not agree with our data, which on the contrary indicate the optimal nodule diameter should be 35 mm or less.

Recurrence of diseases following orthotopic liver transplantation

Long-term graft survival and mortality after liver transplantation continue to improve. However, disease recurrence remains a major stumbling block, especially among patients with hepatitis C. Chronic hepatitis C recurs to varying degrees in nearly all patients who undergo transplantation. Transplantation for hepatitis C is associated with higher rates of graft failure and death compared with transplantation for other indications, and retransplantation for hepatitis C related liver failure remains controversial. Recurrence of hepatitis B has been markedly reduced with improved prophylactic regimens. Further, rates of hepatocellular carcinoma recurrence have also decreased, as improved patient selection criteria have prioritized transplantation for those with a low risk of recurrence. Primary biliary cirrhosis recurs in some patients, but it is often relatively mild. Autoimmune liver disease has also been shown to have a relatively benign post-transplantation course, but some studies have indicated that it slowly progresses in most recipients. It has been recently reported that alcoholic liver disease liver transplant recipients who return to drinking have worsened mortality. In such patients worse outcomes are not due to graft failure, but instead to other comorbidities. Recurrences of other diseases, including nonalcoholic steatohepatitis and primary sclerosing cholangitis, are now being recognized as having potentially detrimental effects on graft survival and mortality. Expert clinical management may help prevent and treat complications associated with disease recurrence.

Liver Transplantation and Incidentally Found Hepatocellular Carcinoma in Liver Explants: Need for a New Definition?

BACKGROUND

"Incidentally" identified hepatocellular carcinoma (iHCC) in liver explants after liver transplantation (LTx) is a frequently reported finding, which is characterized with a good prognosis. The purpose of this study was to evaluate the outcome of patients with these tumors in our series and in literature reports, and to compare their prognosis to that of HCC diagnosed preoperatively.

METHODS

From April 1998 to December 2003, 432 patients underwent deceased-donor LTx at our center for nonmalignant indications. An additional 31 patients with a preoperative known HCC (pkHCC) received deceased-donor grafts. A literature search was performed intending to estimate the incidence of iHCC in liver explants and the outcome after LTx.

RESULTS

iHCC was found in 5 of the 432 patients. All five patients are currently alive without evidence of tumor recurrence after a median follow-up of 43 months. On the other hand, in the group of the 31 patients with pkHCC, 22 of them are at the moment alive in a median follow-up of 28 months. When comparing the two groups, no difference in survival could be found (P=0.1419 in log-rank test). Literature reports of 705 instances with iHCC over the past 20 years showed a statistical "better survival" in only 24 cases.

CONCLUSION

Literature reports showed a remarkable "deviation" of the expected tumor characteristics for the iHCC. Obviously, this is because of a widely characterization of iHCC, including also tumors which are rather undetected HCC during the waiting time to LTx. A more precise definition for the iHCC is needed.

Hepatitis C virus infection with hepatocellular carcinoma: not a controversial indication for liver transplantation

BACKGROUND

The association of hepatocellular carcinoma (HCC) and chronic hepatitis C virus (HCV) infection has been identified as a potential contraindication for orthotopic liver transplantation (LT) because of lower survival rate compared with other indications.

AIM

Evaluate the outcome of patients with and without HCC and cirrhosis with and without chronic HCV infection undergoing transplantation. Determine the postLT HCC recurrence rate and frequency of de novo postLT HCC.

PATIENTS AND METHODS

United Network for Organ Sharing (UNOS) data was collected from January 1998 to December 2002. Cohort included 17,968 patients (11,552 M; 6,416 F) with a mean age of 51 (18-87) years. Four groups were established: HCV (n = 7,079), HCC (n = 611), HCV+HCC (n = 1,078), and no HCV/no HCC (n = 9,200). The overall survival rate was calculated at 24 and 48 months postLT.

RESULTS

Patient survival at 24 months and 48 months was 84% and 75% for HCV, 84% and 68% for HCC, 78% and 72% for HCV+HCC, and 85% and 80% for no HCV/no HCC, respectively. Survival at 48 months among the two groups was not significantly different (NS). Further analysis of these groups revealed a statistically significant advantage in survival at 48 months postLT for the no HCV/no HCC group when compared with the HCV group.(P < 0.05) The reported rate of postLT HCC recurrence and de novo postLT HCC was 3.3% and 0.05%, respectively.

CONCLUSION

In this large cohort of U.S. patients, HCC does not have an impact on the survival of LT patients infected with HCV.

Quality of life in adult survivors beyond 10 years after liver, kidney, and heart transplantation

BACKGROUND

The yearly increasing survival rates testify to the success of transplantation, but questions remain relating to the quality of life (QOL) associated with long-term survival.

METHODS

A sample of 126 liver recipients (Liver-R), 229 kidney recipients (Kidney-R), and 113 heart recipients (Heart-R) with more than 10 years posttransplant follow-up were included in the study with a response rate of 86%. Respondents were matched with healthy subjects recruited from general population (GP). The three groups of recipients and GP subjects completed a French version of the questionnaire used by the National Institute of Diabetes and Digestive and Kidney Disease, Pittsburgh, PA, and were compared for each score, with adjustments for age and sex.

RESULTS

Personal function and measures of disease by the transplant recipients were significantly worse than in the GP (P<0.0001), with the worst score in Kidney-R. No difference, either between organs or between organs and GP, was found regarding the perceived social and role function. However, for psychologic status and general health perception, Kidney-R had the least favorable performance when compared with GP (P<0.01) and also when compared with Liver-R (P<0.05). With the exception of Kidney-R, the well-being index of Liver-R and Heart-R was significantly better than the GP (P<0.001 and P<0.05, respectively).

CONCLUSIONS

The QOL beyond 10 years after liver, heart, and kidney transplantation is quite similar to the GP, with Kidney-R starting out as the worst, Heart-R as intermediate, and Liver-R the best.

The natural history and outcome of liver transplantation in hepatitis C virus-infected recipients

1. Recurrence of hepatitis C infection is universal and immediate after liver transplantation. 2. Graft and patient survival is reduced in liver transplantation recipients with recurrent hepatitis C virus infection compared with hepatitis C virus-negative recipients. 3. The natural history of chronic hepatitis C is accelerated after liver transplantation compared with nontransplantation chronic hepatitis C; 20% to 40% of patients progress to allograft cirrhosis within 5 years, compared with less than 5% of nontransplantation patients. 4. The rate of fibrosis progression is not uniform and may change over time. 5. The rate of progression from cirrhosis to decompensation is accelerated after liver transplantation. The rate of decompensation is >40% at 1 year and >60% at 3 years, compared with <5% and <10%, respectively, in immunocompetent patients. 6. The rate of progression from decompensation to death is also accelerated after liver transplantation. The 3-year survival is <10% after the onset of hepatitis C virus-related allograft failure, compared with 60% after decompensation in immunocompetent patients.

Host and donor risk factors before and after liver transplantation that impact HCV recurrence

1. The natural history of hepatitis C after liver transplantation is variable. Several factors, including those related to the virus, the host, the environment and the donor, are probably implicated in the outcome. 2. The immune status per se likely represents the main significant variable in influencing disease severity in hepatitis C virus-infected patients. Findings that support this statement include the higher aggressivity of hepatitis C in immunocompromised liver transplant recipients as compared with that observed in immunocompetent patients, both before and after the development of compensated cirrhosis, and the significant association described between the degree of immunosuppression and disease severity. 3. Similar to that observed in the immunocompetent population, the age at the time of infection (age of the donor) strongly affects posttransplantation hepatitis C virus-related disease progression. 4. Hepatitis C-related disease progression is faster in patients who underwent transplantation in recent years as compared with those who underwent transplantation in earlier cohorts. The increasing age of the donor and the use of stronger immunosuppression may, in part, explain the worse outcomes seen in recent years. 5. Additional host-related variables predictive of outcome include the immunogenetic background, the timing of recurrence, and the early histologic findings.

Treatment strategies for hepatitis C: intervention prior to liver transplant, pre-emptively or after established disease

Cirrhosis secondary to chronic hepatitis C virus (HCV) infection accounts for most liver transplants performed in the United States and European transplant centers. Given the high prevalence of HCV infection in the general population, the lack of consistently effective antiviral therapy, and the eventual progression to cirrhosis of a subset of those infected, predictions for the future are that the number of patients in need of transplantation will increase in the coming decade. In addition, viral infection recurs nearly universally leading to the development of chronic HCV in most recipients and progression to cirrhosis after a median of 9 to 12 years in a significant proportion of these recipients.

Longitudinal prospective evaluation of quality of life in adult patients before and one year after liver transplantation

We assessed the impact of liver transplantation (LT) on the quality of life (QOL) of French recipients 1 year after surgery. A French version of the questionnaire used by the National Institute of Diabetes and Digestive and Kidney Disease-Pittsburg, USA (NIDDK), was validated by the back-translation method. Five QOL domains were evaluated: measures of disease, psychological distress, personal function, social function, and general health perception. Patients enrolled onto the waiting list completed the questionnaire before and 1 year after LT. Respondents were age- and gender-matched with healthy subjects recruited from the general population (GP). One year after LT, the analysis of data from 67 consecutive patients showed dramatic improvement in the five domains. Compared with baseline, patients noted fewer disease-related symptoms (P <.0001) and lower level of distress overall (P <.001). However, levels of distress caused by excess appetite (P <.01), trembling (P <.05), and headaches (P =.06) were more likely to increase than decrease. Twenty-five percent of patients prevented by their disease from going to work before LT were no longer so limited at 1-year follow-up. General health perception improved remarkably, with seven times as many recipients reporting improved health as reporting worse health. A correlation was found between the pretransplantation severity of cirrhosis and the social and role function after LT (P <.05). In summary, the French version of the NIDDK questionnaire seems to be reliable. The results of transplant recipients were generally close to those of the general population. Although it is not a true return to normal status, it approaches it.
