Abstract

Background: Liver transplantation (LT) provides better outcome than surgical resection (SR) although both are acceptable surgical options for hepatocellular carcinoma (HCC). It is unclear whether non-clinical factors drive treatment decisions. Our goal is to identify factors that may affect treatment decisions.

Methods: Patients aged 18-74 with T2 HCC undergoing either LT or SR in Surveillance, Epidemiology, and End Results Database from 2004 to 2014 were included. Healthcare resources data were analyzed to assess factors that predict utilization of LT versus SR, adjusted for demographic, clinical outcomes, and socioeconomic factors.

Results: 51% of patients (Total N = 2616) received LT, with a substantial state-level variation in LT rates (0.0%-66.9%). Higher LT center density [OR = 1.04 per 1% increment, P < 0.01], male gender (OR = 1.38, P = 0.02), and numbers of potential donors (OR = 1.19, P = 0.03) were positively associated with LT utilization. Conversely, higher incidence of chronic liver disease/cirrhosis (OR = 0.41 per one additional case per 100,000 populations, P = 0.001) and minority populations were negatively correlated with LT utilization. Notably, short-term surgical outcomes (in-hospital LT & SR mortality) were not associated with LT utilization.

Conclusion: Liver transplant center density and organ availability, but not surgical outcomes, affect utilization of LT. Future studies should focus on increasing availability of resources.
