Abstract

Background & Aims Little is known about provider and health system factors that affect receipt of active therapy and outcomes of patients with hepatocellular carcinoma (HCC). We investigated patient, provider, and health system factors associated with receipt of active HCC therapy and overall survival. Methods We performed a national, retrospective cohort study of all patients diagnosed with HCC from January 1, 2008 through December 31, 2010 (n = 3988) and followed through December 31 2014 who received care through the Veterans Administration (128 centers). Outcomes were receipt of active HCC therapy (liver transplantation, resection, local ablation, transarterial therapy, or sorafenib) and overall survival. Results In adjusted analyses, receiving care at an academically affiliated Veterans Administration hospital (odds ratio [OR], 1.97; 95% confidence interval [CI], 1.60–2.41) or a multi-specialist evaluation (OR, 1.60; 95% CI, 1.15–2.21), but not review by a multidisciplinary tumor board (OR, 1.19; 95% CI, 0.98–1.46), was associated with a higher likelihood of receiving active HCC therapy. In time-varying Cox proportional hazards models, liver transplantation (hazard ratio [HR], 0.22; 95% CI, 0.16–0.31), liver resection (HR, 0.38; 95% CI, 0.28–0.52), ablative therapy (HR, 0.63; 95% CI, 0.52–0.76), and transarterial therapy (HR, 0.83; 95% CI, 0.74–0.92) were associated with reduced mortality. Subspecialist care by hepatologists (HR, 0.70; 95% CI, 0.63–0.78), medical oncologists (HR, 0.82; 95% CI, 0.74–0.91), or surgeons (HR, 0.79; 95% CI, 0.71–0.89) within 30 days of HCC diagnosis, and review by a multidisciplinary tumor board (HR, 0.83; 95% CI, 0.77–0.90), were associated with reduced mortality. Conclusions In a retrospective cohort study of almost 4000 patients with HCC cared for at VA centers, geographic, provider, and system differences in receipt of active HCC therapy are associated with patient survival. Multidisciplinary methods of care delivery for HCC should be prospectively evaluated and standardized to improve access to HCC therapy and optimize outcomes.
