Differences in the surgical management of early-stage hepatocellular carcinoma at minority versus non-minority-serving hospitals.

ABSTRACT

BACKGROUND: We examined differences in surgical intervention at minority-serving hospitals versus non-minority-serving hospitals among patients with early-stage hepatocellular carcinoma. We also investigated associations between surgical management and overall survival, stratified by minority-serving hospital status. METHODS: Patients with early-stage hepatocellular carcinoma, defined as cT1, were identified within the National Cancer Database (2004-2018). The primary outcome was surgical intervention (resection, ablation, or transplantation). The proportion of minority (non-Hispanic Black or Hispanic) patients treated at each facility was determined, and hospitals in the top decile were considered minority-serving hospitals. RESULTS: A total of 46,703 patients with early-stage hepatocellular carcinoma were identified, of whom 4,214 (9.0%) were treated at minority-serving hospitals. Patients treated at minority-serving hospitals were less likely to undergo surgical intervention than patients treated at non-minority-serving hospitals (odds ratio = 0.87, 95% confidence interval 0.81-0.94). Minority patients treated at non-minority-serving hospitals were less likely to undergo surgical intervention than White patients (odds ratio = 0.86, 95% confidence interval 0.82-0.90) and had a further associated decrease in the likelihood of surgical intervention when treated at minority-serving hospitals (odds ratio = 0.81, 95% confidence interval 0.69-0.94). Regardless of minority-serving hospital status, surgery was associated with improved overall survival. There were no clinically meaningful differences in overall survival between White and minority patients who underwent surgery either at minority-serving hospitals or non-minority-serving hospitals. CONCLUSIONS: Patients with early-stage hepatocellular carcinoma had an associated decrease in the likelihood of surgical intervention when treated at minority-serving hospitals. Minority patients treated at minority-serving hospitals had an associated decrease in the likelihood of surgery, but to a lesser extent when treated at non-minority-serving hospitals. Surgery was associated with improved overall survival regardless of minority or minority-serving hospital status.
