Racial, ethnic, and socioeconomic disparities impact post-liver transplant survival in patients with hepatocellular carcinoma.

INTRODUCTION AND OBJECTIVES

Liver transplantation can be a curative treatment for patients with hepatocellular carcinoma (HCC); however, the morbidity and mortality associated with HCC varies by socioeconomic status and race and ethnicity. Policies like Share 35 were implemented to ensure equitable access to organ transplants; however, their impacts are unclear. We aimed to characterize differences in post-liver transplant (LT) survival among patients with HCC, when considering race and ethnicity, income, and insurance type, and understand if these associations were impacted by Share 35.

MATERIALS AND METHODS

We conducted a retrospective cohort study of 30,610 adult LT recipients with HCC. Data were obtained from the UNOS database. Survival analysis was carried out using Kaplan-Meier curves, and multivariate Cox regression analysis was used to calculate hazard ratios.

RESULTS

Men (HR: 0.90 (95% CI: 0.85-0.95)), private insurance (HR: 0.91 (95% CI: 0.87-0.92)), and income (HR: 0.87 (95% CI: 0.83-0.92)) corresponded with higher post-LT survival, when adjusted for over 20 demographic and clinical characteristics (Table 2). African American or Black individuals were associated with lower post-LT survival (HR: 1.20 (95% CI: 1.12-1.28)), whereas. Asian (HR: 0.79 (95% CI: 0.71-0.88)) or Hispanic (HR: 0.86 (95% CI: 0.81-0.92)) individuals were associated with higher survival as compared with White individuals (Table 2). Many of these patterns held in the pre-Share 35 and Share 35 periods.

CONCLUSIONS

Racial, ethnic, and socioeconomic disparities at time of transplant, such as private insurance and income, influence post-LT survival in patients with HCC. These patterns persist despite the passage of equitable access policies, such as Share 35.
