RESUMO

Liver transplantation (LT) offers the best chance of survival in selected patients with hepatocellular carcinoma (HCC). Wait-list mortality or dropout due to tumor progression can be significant, and therefore, timely transplantation is critical. Liver grafts discarded by outside organ procurement organizations are a potential source of grafts for low Model for End-Stage Liver Disease tumor patients. The primary aim of this study was to assess the disease-free and overall survival of patients with HCC transplanted with imported liver grafts (ILGs). Review of all patients transplanted for HCC between June 2005 and December 2014 was performed. Data on demographics, survival, and HCC recurrence were analyzed. During this time period, 59 out of 190 (31%) recipients with HCC received ILG. Of these 59 grafts, 54 were imported from within the region and 5 were from national offers (outside the region). The mean cold ischemia time for local liver grafts (LLGs) was 4.1 ± 1.5 hours versus 5.1 ± 1.4 hours for ILG (P < 0.001). The 1-, 3-, and 5-year patient survival was 90%, 85%, and 83% and 85%, 80%, and 79% for LLG and ILG (P = 0.08), respectively. The observed disease recurrence rate for both LLG and ILG recipients was equivalent. The median wait-list time for HCC recipients was 43 days (range, 2-1167 days). In conclusion, with careful graft assessment, the use of ILGs results in comparable outcomes following LT and no increased risk of HCC recurrence. Use of ILGs maximizes the donor pool and results in a higher rate of transplantation for HCC recipients. Liver Transplantation 23 299-304 2017 AASLD.

RESUMO

Liver transplantation has become the best and most durable treatment for both acute and chronic liver disease. Over 1400 liver transplants have been performed at the Ochsner Clinic since the first successful transplant in 1987. Since its inception, the program has gone through several changes and advancements and has become one of the largest liver transplant programs in the United States. We have helped evolve steroid sparing immunosuppression and the use of extended criteria, donor organs. Establishment of criteria for the selection of recipients for re-transplantation has resulted in better than expected short and long-term results. Our center has faced the challenge of Hurricane Katrina and overcome it. We have improved steadily in both outcomes and transplants performed. The Ochnser Clinic Liver Transplant program will continue to improve access and outcomes for all patients with liver disease.

RESUMO

Post-transplant malignancy of donor origin is a rare complication of organ transplantation, most likely transmitted as micrometastases within the parenchyma of the donor organ or from circulating tumor cells contained within the organ. Patient survival is dependent upon early diagnoses, and differentiation of the malignancy as of donor or recipient derivation is important in developing a treatment modality. The utilization of fluorescent in situ hybridization chromosome analysis and DNA sequence analysis of the tumor cells can assist in this determination. This case report describes the management of donor transmitted malignant melanoma in a liver graft recipient and a review of the current literature.

RESUMO

OBJECTIVE: Hepatitis C (HCV) is now the most common indication for orthotopic liver transplantation (OLT). While graft reinfection remains universal, progression to graft cirrhosis is highly variable. This study examined donor, recipient, and operative variables to identify factors that affect recurrence of HCV post-OLT to facilitate graft-recipient matching. METHODS: Retrospective review of 307 patients who underwent OLT for HCV over a 10-year period at our center. Recurrence of HCV was identified by the presence of biochemical graft dysfunction and concurrent liver biopsy showing diagnostic pathologic features. Time to recurrence was the endpoint for statistical analysis. Five donor, 6 recipient, and 2 operative variables that may affect recurrence were analyzed by univariate comparison and Cox proportional hazard regression models. RESULTS: Recurrence-free survival in the 307 study patients was 69% and 34% at 1 and 5 years, respectively. Four predictive variables related to either donor or recipient characteristics were identified. Advanced donor age, prolonged donor hospitalization, increasing recipient age, and elevated recipient MELD scores were found to increase the relative risk of HCV recurrence. Examination of HLA disparity between donors and recipients demonstrated no correlation between class I or class II mismatches and recurrence-free survival. CONCLUSIONS: We have identified donor and recipient characteristics that significantly predict hepatitis C recurrence following liver transplantation. These factors are identifiable before transplant and, if considered when matching donors to HCV recipients, may decrease the incidence of HCV recurrence after OLT. A change in the current national liver allocation system would be needed to realize the full value of this benefit.

RESUMO

The efficacy of orthotopic liver transplantation (OLT) for hepatocellular carcinoma (HCC) associated with hepatitis C virus (HCV) is not well defined. This study examines the variables that may determine the outcome of OLT for HCC in HCV patients. From 1990 to 1999, 463 OLTs were performed for HCV cirrhosis. Of these patients, 67 with concurrent HCC were included in the study. Univariate and multivariate analyses considered the following variables: gender, pTNM stage, tumor size, number of nodules, vascular invasion, incidental tumors, adjuvant chemotherapy, preoperative chemoembolization, alpha-fetoprotein (AFP) tumor marker, lobar distribution, and histological grade. Overall OLT survival of HCV patients diagnosed with concomitant HCC was significantly lower when compared to patients who underwent OLT for HCV alone at 1, 3, and 5 years (75%, 71%, and 55% versus 84%, 76%, and 75%, respectively; P < 0.01). Overall survival of patients with stage I HCC was significantly better than patients with stage II, III, or IV (P < .05). Eleven of 67 patients developed tumor recurrence. Sites of recurrence included transplanted liver (5), lung (5), and bone (1). Twenty-four of 67 patients (36%) died during the follow-up time. Causes of deaths included recurrent HCC in 8 of 24 patients (12%) and recurrent HCV in 3 of 24 patients (4.5%), whereas 13 (19.5%) patients died from causes that were unrelated to HCV or HCC. Both univariate and multivariate analysis demonstrated that pTNM status (I versus II, III, and IV; P < .05) was a reliable prognostic indicator for patient survival. Presence of vascular invasion (P = .0001) and advanced pTNM staging (P = .038) increased risk of recurrence. Multivariate analysis showed that pretransplant chemoembolization and adjuvant chemotherapy reduced risk of death after OLT in HCC recipients. In conclusion, this study demonstrates the effectiveness of OLT for patients with HCC in a large cohort of chronic HCV patients. Advanced tumor stage, and particularly vascular invasion, are poor prognostic indicators for tumor recurrence. Early pTNM stage, adjuvant chemotherapy, and preoperative chemoembolization were associated with positive outcomes for patients who underwent OLT for concomitant HCV and HCC.
