Abstract
Objective: This study aimed to explore the influence of social support on the survival outcomes of patients with nasopharyngeal carcinoma (NPC). We examined whether the combined proxy influenced whether patients were more likely to receive radiotherapy. Methodology: data were collected from the 18 registries of the National Cancer Institute’s Surveillance, Epidemiology, and End Results database. The association between both insurance status and marital status and disease-specific survival rates were evaluated with a multivariate Cox proportional-hazards regression model to calculate the hazard ratios and associated confidence intervals. Odds ratio (OR) computed by logistic regression was also used to examine the relationship between the receipt of radiotherapy and insurance and marital status. Results: insured and uninsured patients differed significantly in T-stage, N-stage, M-stage, radiotherapy use, race, and marital status. The uninsured-non-married patients showed the lowest 5-year disease-specific survival rates. We further found unmarried patients with either Medicaid (OR, 0.40), or no insurance (OR, 0.24) had lower odds of receiving radiotherapy than those with insurance at diagnosis. Conclusions: uninsured-unmarried NPC patients had a significantly higher risk of distant metastasis at diagnosis, poorer 5-year disease-specific survival, and were less likely to receive radiotherapy than insured-married patients.
