Abstract
Background/aims: We studied the impact of socioeconomic status (SES) on mortality in hepatocellular carcinoma patients and analyzed the effect of SES on initial treatment allocation.
Methods: A cohort study was conducted using data from the National Health Insurance Service- National Sample Cohort of Korea. A total of 3,032 hepatocellular carcinoma patients who were newly diagnosed between January 2003 and December 2013 were included. Income level was categorized as Medical Aid and ≤30th, 31st-70th, or >70th percentile as an SES indicator.
Results: The proportion of Medical Aid was 4.3%. The highest risks of all-cause mortality associated with Medical Aid were evident in the transcatheter arterial chemoembolization group (fully adjusted hazard ratio [HR], 2.40; 95% confidence interval [CI], 1.25 to 4.58), the other treatments group (fully adjusted HR, 2.86; 95% CI, 1.85 to 4.41), and the no treatment group (fully adjusted HR, 2.69; 95% CI, 1.79 to 4.04) but not in the curative treatment group. An association between the lower-income percentile and higher liver cancer-specific mortality was also observed, except in the curative treatment group. The association between income percentile and all-cause mortality was nonlinear, with a stronger association in the lower-income percentiles than in the higher income percentiles (p-value for nonlinear spline terms <0.05).
Conclusions: Patients in the lower SES group, especially patients not eligible for curative treatment, had an increased risk of mortality. In addition, the association between SES and the risk for mortality was stronger in the lower-income percentile than in the moderate to higher income percentiles.
