Sinonasal adenocarcinoma: A population-based analysis of demographic and socioeconomic disparities

Background Sinonasal adenocarcinoma (SNAC) is a rare tumor. The impact of health disparities on survival, stage at presentation, and utilization of surgery is not well understood in patients with SNAC. Methods The Surveillance, Epidemiology, and End Results database was queried for cases of SNAC from 1973 to 2015. Cases were analyzed to assess for disparities in presentation, treatment, and survival. Results SNAC was identified in 630 patients. In a multivariate model of overall survival, an age increase of 10 years (Hazard Ratio (HR) = 1.37, p < 0.001), male sex (HR = 1.26, p = 0.045), and more recent decade of diagnosis (HR = 0.74, p < 0.001) were significantly related to time-to-death. There is a higher rate of SNAC-related death in counties with more rural populations (p = 0.027). Conclusion Future interventions targeting rural and less well-educated populations may improve care with the goal of increasing the span of healthy life and reducing survival disparities related to SNAC.
