2019
417Background: To assess the impact of hospital volume and type on survival in patients with hepatocellular carcinoma (HCC). Methods: Patients with histopathological or imaging-based diagnosis of HCC were identified from the 2003-2015 National Cancer Database (NCDB). First-line treatment was stratified as liver transplant, surgical resection, interventional oncology (IO) and chemotherapy. Hospital volume was stratified as high (ranking among top 10% in case numbers) and low volume, separately for each treatment modality. Hospital type was categorized as academic and non-academic. Overall survival was assessed using multivariable Cox proportional hazards models. Results: A total of 63,877 patients were included (transplant n = 10,596, surgical resection n = 11,132, IO n = 12,286, chemotherapy n = 29,863). Of 1,261 hospitals systems which treated HCC, 226 (17.9%) were academic centers and 1,035 (82.1 %) were non-academic centers. Mean number of cases treated annually was higher in academic centers (55.2; 34...
