Life Expectancy after Liver Transplantation for NASH.

Introduction: Non-Alcoholic Steatohepatitis is an increasing reason for liver transplantation in the western world. Knowledge of recipient life expectancy may assist in prudent allocation of a relatively scarce supply of donor livers. Research Questions: We calculated life expectancies for Non-alcoholic steatohepatitis (NASH) patients both at time of transplant and one year later, stratified by key risk factors, and examined whether survival has improved in recent years. Design: Data on 6635 NASH patients who underwent liver transplantation in the MELD era (2002-2018) from the United States OPTN database were analyzed using the Cox proportional hazards regression model and life table methods. Results: Factors related to survival were age, presence of diabetes or hepatic encephalopathy (HE), and whether the patient required dialysis in the week prior to transplant. Other important factors were whether the patient was working, hospitalization prior to transplant, ventilator support, and length of hospital stay (LOS). Survival improved over the study period at roughly 4.5% per calendar year during the first year posttransplant, though no improvement was observed in those who had survived one year. Conclusion: Life expectancy in NASH transplant patients was much reduced from normal, and varied according to age, medical factors, status at transplant, and post transplant course. Over the 17-year study period, patient survival improved markedly during the first year posttransplant, though not thereafter. The results given here may prove helpful in medical decision-making regarding treatment for both liver disease and other medical conditions, as they provide both clinicians and their patients with evidence-based information on prognosis.

Life Expectancy After Liver Transplantation for Hepatocellular Carcinoma With Cirrhosis.

BACKGROUND: Hepatocelluar carcinoma, the most common primary liver cancer, has a historically dire prognosis. For hepatic cancer patients with cirrhosis who underwent liver transplantation, we sought to calculate life expectancies both at time of transplant and several years later, stratified by some key variables, and to determine if survival has improved in recent years. METHODS: Data on 13,797 hepatic cancer patients with cirrhosis who underwent liver transplantation in the MELD era (2002-2018) from the US Organ Procurement and Transplantation Network database were analyzed using the Cox proportional hazards regression model and life table methods. RESULTS: The major factors related to survival were age, donor age, transplant year, diabetes, functional status, and the presence of severe hepatic encephalopathy. Survival was significantly worse with increasing age and decreasing functional status level. There was no significant difference in survival between males and females. Survival improved over the study period, at 5% per calendar year during the first 5 years post transplant, and 1% per year thereafter. CONCLUSIONS: Life expectancies were markedly reduced from normal, even among 5-year survivors with the most favorable characteristics. Survival improved modestly over the years 2002-2018.

Life Expectancy after Liver Transplantation for Non-Cirrhotic Hepatocellular Carcinoma.

BACKGROUND: Hepatocelluar carcinoma typically occurs with underlying cirrhosis. However roughly 20% of cases arise in a non-cirrhotic liver. There is limited literature that addresses the long-term survival of the narrow subgroup who received transplantation. For such patients we sought to calculate life expectancies both at time of transplant and several years later, stratified by key risk factors, and to determine if survival has improved in recent years. Such information can be helpful in making treatment decisions. METHODS: Data on 4,373 non-cirrhotic HCC patients who underwent liver transplantation in the MELD era (2002-2018) from the United States OPTN database were analyzed using the Cox proportional hazards regression model and life table methods. RESULTS: Demographic and past medical history factors related to survival were patient age, donor age over 20, and the presence of ascites or severe hepatic encephalopathy. Survival did not vary by race or sex. HCC-specific factors significantly related to survival were the total number of tumors, extrahepatic spread, lymph node involvement, satellite lesions, micro- or macrovascular invasion, tumor differentiation (grade), and pre-transplant treatment. Survival improved over the study period, at 4% per calendar year during the first 5 years post transplant and 1% per year thereafter. CONCLUSIONS: Life expectancy in non-cirrhotic HCC transplant patients is much reduced from normal, and varies according to age and tumor-related factors. Survival improved modestly over the study period.

Life Expectancy After Liver Transplantation for Alcoholic Cirrhosis.

BACKGROUND: Alcohol-associated liver disease is the leading cause of liver transplantation in the western world. For these patients we calculated life expectancies both at time of transplant and several years later, stratified by key risk factors, and determined if survival has improved in recent years. METHODS: Data on 14 962 patients with alcohol-associated liver disease who underwent liver transplantation in the MELD era (2002-2018) from the United States Organ Procurement and Transplantation Network database were analyzed using the Cox proportional hazards regression model and life table methods. RESULTS: Demographic and past medical history factors related to survival were patient age, presence of diabetes or severe hepatic encephalopathy, and length of hospital stay. Survival improved over the study period, at roughly 3% per calendar year during the first 5 years posttransplant and 1% per year thereafter. CONCLUSIONS: Life expectancy in transplanted patients with alcohol-associated liver disease was much reduced from normal, and varied according to age, medical risk factors, and functional status. Survival improved modestly over the study period. Information on patient longevity can be helpful in making treatment decisions.
