Liver Transplantation for Hepatocellular Carcinoma in Young Adults: A United Network for Organ Sharing Study.

Purpose: Orthotopic liver transplantation (OLT) is curative for hepatocellular carcinoma (HCC). HCC is typically a disease of older adults (OAs); therefore, characteristics and outcomes of OLT for young adults (YAs) (ages 18–40) are not described. The objective of this study was to assess the characteristics and outcomes of YAs with HCC receiving OLT and compare these to OAs (ages >40 years). Methods: YAs with HCC who had OLT from the United Network for Organ Sharing (UNOS) database were included in this study. As a comparison group, OAs with HCC were matched 4:1 to the YA group. Descriptive statistics of demographics, comorbidities, and outcomes were generated. Kaplan–Meier product limit estimates were used to assess patient and graft survival. Conditional logistic regression and Cox proportional hazards frailty models were used to compare the groups. Results: A total of 464 YAs received OLT for HCC. The most common underlying liver diseases were hepatitis C virus (21.3%), hepatitis B virus (HBV, 15.5%),...
