BACKGROUND Racial/ethnic and socioeconomic disparities are assumed to negatively affect treatment and outcomes for hepatocellular carcinoma (HCC). Our aim was to investigate the interaction of racial/ethnic and socioeconomic factors with stage of disease and type of treatment facility in receipt of treatment and overall survival (OS) of patients with HCC. METHODS All patients with primary HCC in the US Safety-Net Collaborative database (2012-2014) were included. Patients were categorized into "safety-net" or "tertiary referral center" based on where they received treatment. Socioeconomic factors were determined at the zip-code level and included median income and percent of adults who graduated from high-school. Primary outcomes were receipt of treatment and OS. RESULTS On MV Cox regression, neither race/ethnicity, median income, nor care provided at a SNH were associated with decreased OS (all p > 0.05). Independent predictors of decreased OS included lack of insurance (HR 1.34), less educational attainment (HR 1.59) higher MELD score (HR 1.07), higher stage at diagnosis (II:HR 1.34, III:HR 2.87, IV:HR 3.23), and not receiving treatment (HR 3.94) (all p < 0.05). Factors associated with not receiving treatment included history of alcohol abuse (OR 0.682), increasing MELD (OR 0.874), higher stage at diagnosis (III: OR 0.234, IV: OR 0.210) and care at a safety net facility (OR 0.424) There were no racial/ethnic or socioeconomic disparities in receipt of treatment. CONCLUSIONS There is no intrinsic or direct association of race/ethnicity, socioeconomic status, or being treated at select safety-net hospitals with worse outcomes. Poor liver function, no insurance, and advanced stage of presentation are the main determinants of not receiving treatment and decreased survival.

D006528 Carcinoma, Hepatocellular A primary malignant neoplasm of epithelial liver cells. It ranges from a well-differentiated tumor with EPITHELIAL CELLS indistinguishable from normal HEPATOCYTES to a poorly differentiated neoplasm. The cells may be uniform or markedly pleomorphic, or form GIANT CELLS. Several classification schemes have been suggested.

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
