The effect of insurance status on overall survival (OS) of patients with cutaneous T-cell lymphoma (CTCL) is unclear. We identified 11,861 patients from the US National Cancer Data Base diagnosed with CTCL from 2004-2014, of which 6088 had private insurance, 756 had Medicaid, 4536 had Medicare, and 481 are uninsured. Privately insured patients were more likely to present at an early stage (p < .001). On multivariate Cox regression analysis, privately insured patients had significantly longer OS than patients with Medicaid (HR: 1.936, 95% CI: 1.680-2.230, p < .001), Medicare (HR: 1.342, 95% CI: 1.222-1.474, p < .001), or no insurance (HR 1.849, 95% CI: 1.539-2.222, p < .001). The survival advantage of privately insured patients persisted on relative survival and propensity score-matched analyses. In conclusion, privately insured patients were more likely to present at an early stage, and had longer OS than patients who were Medicaid-, Medicare-, or not insured.
