Race not rural residency is predictive of surgical treatment for hepatocellular carcinoma: Analysis of the Texas Cancer Registry

Background and ObjectivesRural patients have poor access to specialists and are less likely to receive evidence-based cancer care. We hypothesized that hepatocellular carcinoma(HCC) patients from rural counties in Texas would be less likely to receive surgical therapy than those from urban areas. MethodsThe Texas Cancer Registry was queried (2000-2008). County-level data included rural or urban designation and income variables derived by zip code. Surgical intervention included: (i) ablation, (ii) resection-partial or total lobectomy, or (iii) transplantation. A multinomial logistic regression was created to determine predictors of intervention. ResultsFive thousand thirty seven HCC patients were identified (86% urban) for study. A multinomial regression demonstrated, older age, African-American race, and lower income reduced the likelihood of ablation. Younger age, female gender, Caucasian, and Asian/other race predicted surgical resection, or transplantation. Hispanic race was associated with lower likelihood of resection (RRR 0.75) and transplantation (RRR 0.74), whereas African-American race was associated with pronounced decrease for transplantation (RRR 0.48). Area of residency was not predictive of intervention. ConclusionsRural residency did not decrease the likelihood of surgical intervention for hepatocellular carcinoma. Race and income continue to be associated with significant treatment disparity. Additional investigation should focus on factors that govern the selection of resection or transplantation for potentially eligible patients. J. Surg. Oncol. 2016;113:84-88.
