ABSTRACT
Importance Racial disparities in liver transplant (LT) for hepatocellular carcinoma (HCC) may be associated with unequal access to life-saving treatment. Objective:
To quantify racial disparities in LT for HCC and mortality after LT, adjusting for demographic, clinical, and socioeconomic factors. Design, Setting, andParticipants:
This cohort study was a retrospective analysis of United Network Organ Sharing/Organ Procurement Transplant Network (OPTN) data from 2003 to 2021. Participants were adult patients with HCC on the LT waiting list and those who received LT. Data were analyzed from March 2022 to September 2023. Exposures Race and time before and after the 2015 OPTN policy change. Main Outcomes andMeasures:
Proportion of LT from wait-listed candidates, the proportion of waiting list removals, and mortality after LT.Results:
Among 12â¯031 patients wait-listed for LT with HCC (mean [SD] age, 60.8 [7.4] years; 9054 [75.3%] male; 7234 [60.1%] White, 2590 [21.5%] Latinx/o/a, and 1172 [9.7%] Black or African American), this study found that after the 2015 model of end-stage liver disease (MELD) exception policy changes for HCC (era 2), the overall proportion of LT for HCC across all races decreased while the proportion of dropouts on the LT waiting list remained steady compared with patients who did not have HCC. In Kaplan-Meier analysis, Asian patients demonstrated the lowest dropout rates in both era 1 and era 2 (1-year dropout, 16% and 17%, respectively; P < .001). In contrast, Black or African American patients had the highest dropout rates in era 1 (1-year dropout, 24%), but comparable dropout rates (23%) with White patients (23%) and Latinx/o/a patients in era 2 (23%). In both eras, Asian patients had the highest survival after LT (5-year survival, 82% for era 1 and 86% for era 2), while Black or African American patients had the worst survival after LT (5-year survival, 71% for era 1 and 79% for era 2). In the multivariable analysis for HCC LT recipients, Black or African American race was associated with increased risk of mortality in both eras, compared with White race (HR for era 1, 1.17; 95% CI, 1.05-1.35; and HR for era 2, 1.31; 95% CI, 1.10-1.56). Conclusions and Relevance This cohort study of LT candidates in the US found that after the 2015 MELD exception policy change for HCC, the proportion of LT for HCC had decreased for all races. Black or African American patients had worse outcomes after LT than other races. Further research is needed to identify the underlying causes of this disparity and develop strategies to improve outcomes for HCC LT candidates.
