Abstract
Background
Adolescents and young adults (AYA), patients age 15‐39, may experience worse outcomes than pediatric and adult patients. The aim of this paper was to document survival disparities associated with insurance status across the AYA age continuum in the United States.
Methods
We utilized the Surveillance, Epidemiologic, and End Results database to identify 66 556 AYA patients between 2007 and 2014 with 10 International Classification of Childhood Cancer diagnoses and calculated the Cox proportional hazard ratios of death for those with public or no insurance status compared to private insurance. The odds ratios of having a late stage of diagnosis by insurance status were also calculated.
Results
Insurance status was a statistically significant predictor of death for lymphoid leukemia (age 15‐19, 30‐34, and 35‐39), acute myeloid leukemia (age 15‐19 and 25‐29), Hodgkin lymphoma (all ages), non‐Hodgkin lymphoma (age 20‐24, 25‐29, 30‐34, and 35‐39), astrocytomas (age 30‐34), other gliomas (age 25‐29, 30‐34, and 35‐39), hepatic carcinomas (age 25‐29), fibrosarcomas, peripheral nerve and other fibrous tumors (age 30‐34), malignant gonadal germ cell tumors (age 20‐24, 25‐29, 30‐34, and 35‐39), and other and unspecified carcinomas (age 20‐24, 25‐29, 30‐34, and 35‐39), independent of stage at diagnosis. This hazard increased with age for most cancer types. Insurance status strongly predicted the odds of a metastatic cancer diagnosis for lymphoma, fibrosarcomas (age 15‐19), germ cell tumors, and other carcinomas.
Conclusions
AYA in the US experience disparities in cancer survival based on insurance status, independent of late stage of presentation. Patients age 26‐39 may be especially vulnerable to health outcomes associated with poor socioeconomic status, treatment disparities, and poor access to care.
