Hepatocellular carcinoma (HCC) is the fastest‐rising cause of cancer‐related mortality in the United States and is a leading indication for liver transplantation (LT). Changes have been noted in the age of the population with chronic liver disease, but how this change affects patients with HCC is unknown. This study aims to characterize trends and transplant‐associated outcomes among patients ≥65 years old listed for LT with HCC. Using the United Network for Organ Sharing database, we analyzed all patients ≥18 years old listed for LT during 2003‐2017 in the United States in 2 groups (<65 or ≥65 years). Time trends between HCC and non‐HCC patients were compared and stratified by disease etiology. Competing‐risks and Cox proportional hazards regressions associated HCC and age with wait‐list and post‐LT survival. There were 161,724 LT candidates included: 14% were ≥65 years old at listing and 25% had HCC. The proportion of patients ≥65 years old rose significantly faster among those with HCC, as compared with those without HCC (Δ = 0.80; P < 0.001). Age ≥65 years was significantly associated with both wait‐list mortality (adjusted subhazard ratio, 1.51; 95% confidence interval [CI], 1.40‐1.64) and post‐LT mortality (adjusted hazard ratio, 1.50; 95% CI, 1.41‐1.60) in the multivariate analysis. There were significant interactions between age and HCC on both wait‐list (P < 0.001) and post‐LT mortality (P = 0.04), suggesting that older age does not impact patients with HCC as much as patients without HCC. The proportion of older adults with HCC listed for LT has nearly tripled from 2003 to 2017, and the rapidly growing population of older adults with HCC may provide an opportunity to expand LT access without compromising outcomes.
