BACKGROUND: Previous database studies have found gender disparities favoring men in rates of liver transplantation, which resolve in cohorts examining only patients with hepatocellular carcinoma (HCC). AIMS: Our study aims to use two large, multicenter United States (US) databases to assess for gender disparity in HCC treatment regardless of transplant listing status. METHODS: We performed a retrospective database analysis of inpatient admission data from the University Health Consortium (UHC) and the Nationwide Inpatient Sample (NIS), over a 9- and 10-year period, respectively. Adults with a primary discharge diagnosis of HCC, identified using the International Classification of Diseases 9th Edition (ICD-9) code, were included. Series of univariate and multivariate analyses were performed to examine gender disparities in metastasis, liver decompensation, treatment type, and inpatient mortality after controlling for other possible predictors. RESULTS: We included 26,054 discharges from the NIS database and 25,671 patients from the UHC database in the analysis. Women with HCC appear to present less often with decompensated liver disease (OR = 0.79, p < 0.001). Furthermore they are more likely to receive invasive HCC treatment, with significantly higher rates of resection across race and diagnoses (OR = 1.34 and 1.44, p < 0.001). Univariate analyses show that US women have lower unadjusted rates of transplant; however, the disparity resolves after controlling for other clinical and demographic factors. CONCLUSIONS: US women more often receive invasive treatment for HCC (especially resection) than US men with no observed disparity in transplantation rates when adjusted for pre-treatment variables.
