Objectives: To define current use of surgical therapies for hepatocellular carcinoma (HCC) and evaluate the correlation of various patient and hospital characteristics with the receipt of these interventions.
Design: Retrospective cohort.
Setting: California Cancer Registry data linked to the Office of Statewide Health Planning and Development patient discharge abstracts between 1996 and 2006.
Patients: Patients with primary HCC.
Main outcome measures: Receipt of liver transplant, hepatic resection, or local ablation.
Results: Of 12,148 HCC cases, 2390 (20%) underwent surgical intervention. Three hundred eleven (2.56%) received a liver transplant, 1307 (10.8%) underwent resection, and 772 (6.35%) had local ablation. There were wide variations in treatment by race and hospital type. African American and Hispanic patients were less likely than white patients to undergo transplant (P < .05). African American and Hispanic patients were less likely than white and Asian/Pacific Islander patients to have hepatectomy or ablation (P < .05). In multivariable analysis, the apparent differences in surgical intervention by race/ethnicity were decreased when adjusting for the patients' socioeconomic and insurance statuses. Patients with lower socioeconomic status and no private insurance were less likely to receive any surgery (P < .01). Hospital characteristics also explained some variations. Disproportionate Share Hospitals and public, rural, and nonteaching hospitals were less likely to offer surgical treatment (P < .01).
Conclusion: There are significant racial, socioeconomic, and hospital-type disparities in surgical treatment of HCC.
