Racial disparities in the initial treatment of hepatocellular carcinoma in the population 65+ years in the United States.
431 Background: Insufficient evidence exists regarding the initial management of elderly patients with hepatocellular carcinoma (HCC). The purpose of this study was to describe racial differences in initial treatment of 65+ year old patients with HCC diagnosed in the United States (2004-2014). Methods: A retrospective cohort study was conducted using the 1973-2014 Surveillance, Epidemiology and End Results Program (SEER) database of the National Cancer Institute. Patients with primary hepatocellular carcinoma, diagnosed between 2004 and 2014, and with complete information on race, gender, year of diagnosis, age, marital status, region, tumor status at diagnosis and initial treatment were included. Descriptive statistics were used to compare race with sociodemographic and clinical variables. Univariate and multivariate logistic regressions were performed to describe the association of race with receiving any treatment for HCC (local hepatic therapy and surgical treatment versus no treatment). Results: The sample consisted of 25,499 HCC patients: 70.0% White, 9.1% Black, 19.8% API, 1.0% AI; 68.6% male; 46.8% diagnosed in 2004-2009; 54.8% age 65-74, 45.2% 75 and older; 54.7% married, 7.3% Midwest, 13.8% Northeast, 15.7% Southeast; 81.3% first malignant primary indicator, 13.8% metastasis, 49.3% localized site, and 20.9% receiving initial treatment. After controlling for confounding variables, as compared to White patients, African American patients (OR:0.739 95% CI:0.652, 0.839) had decreased odds of receiving initial treatment; and Asian/Pacific Islander patients (OR:1.490 95% CI:1.371,1.618) had increased odds of receiving initial treatment. Conclusions: Racial disparities exist at the presentation of HCC in the 65+ population. African American patients are less likely to receive treatment and Asian/Pacific Islander patients are more likely to receive treatment. Further research is needed to understand these relationships in subpopulations.
