INTRODUCTION: Following passage of the Affordable Care Act, Medicaid access was expanded in several states beginning in 2014. We sought to determine the oncologic implications by comparing outcomes between testicular germ cell tumor patients with Medicaid and those without insurance, and by assessing for changes in outcomes after 2014. METHODS: A total of 18,506 men with seminomatous or nonseminomatous germ cell tumors were identified within the Surveillance, Epidemiology, and End Results database (2007-2016). Multivariable Cox proportional hazards, Fine and Gray competing-risks regression, propensity score matching, cumulative incidence plots and segmented Poisson regression models were used. RESULTS: Compared to no insurance, Medicaid insurance was not associated with differences in all-cause mortality or cancer-specific mortality among seminoma patients (all-cause mortality: HR=1.24, p=0.87; cancer-specific mortality: HR=0.92, p=0.75) or nonseminoma patients (all-cause mortality: HR=1.13, p=0.33; cancer-specific mortality: HR=1.10, p=0.51). Among matched Medicaid and uninsured patients, there was again no difference in cancer-specific mortality for those with seminoma (p=0.81) or nonseminoma (p=0.23). There was a 99% increase in Medicaid enrollment in expansion states in the post-Affordable Care Act era. There was no difference in post-expansion all-cause mortality between expansion states and nonexpansion states for men with seminoma (p=0.42) or nonseminoma (p=0.53). CONCLUSIONS: Medicaid enrollment increased in expansion states following the Affordable Care Act. However, there was no difference in survival between Medicaid patients and uninsured patients, or between patients in expansion states versus nonexpansion states, highlighting the need for population-level policy interventions to improve access and quality of care among testicular cancer patients with Medicaid.
