Abstract

BACKGROUND:

Adolescents and young adults with cancer have inferior survival outcomes compared with younger pediatric patients and older adult patients. Lack of insurance may partly explain this disparity. The objective of this study was to identify associations between insurance status and both advanced-stage cancer and cancer-specific mortality.

METHODS:

Using the Surveillance, Epidemiology, and End Results (SEER) 18 registries, 57,981 patients ages 15 to 39 years were identified who were diagnosed between 2007 and 2010 and had complete insurance and staging information. Multinomial logistic regression models were used to identify associations between insurance type and disease stage, with the models adjusted for sex, age, and race. Cox proportional hazards models were used to estimate cancer-specific mortality.

RESULTS:

Overall, 84% of patients were aged ≥ 25 years, 64% were women, and 79% were privately insured. Compared with patients who had private insurance, those who had nonprivate insurance tended to present with more advanced-stage disease and to die more quickly and more commonly from their cancer. Patients ages 25 to 39 years who had Medicaid coverage or no insurance had 3.2 times and 2.4 times higher odds of having stage IV disease, respectively, than privately insured patients (95% confidence interval [CI], 3.0-3.5 times higher odds and 2.1-2.6 times higher odds, respectively). Among those with stage I/II and III/IV cancers, the risk of death was 2.9 times greater (95% CI, 2.2-3.9 times greater) and 1.7 times greater (95% CI, 1.5-1.9 times greater), respectively, than the risk for privately insured patients. Patients who died from stage III/IV cancers survived at least 2 months longer if they had private insurance.

CONCLUSIONS:

Among young adults, insurance status is independently associated with advanced-stage cancer and the risk of death from cancer, even for patients who have low-stage disease. Broader insurance coverage and access to health care may improve some of the disparate outcomes of adolescents and young adults with cancer.
