    Abstract:
    OBJECTIVE: To determine whether or not patient race and ethnicity affect sinonasal cancer survival. STUDY DESIGN: Retrospective database analysis. SETTING: National Cancer Institute's Surveillance, Epidemiology, and End Results Database, 1988-2010. SUBJECTS AND METHODS: Sinonasal carcinoma cases were extracted according to site codes and histology recode-broad groupings. The cohort was used to calculate disease-specific survival in regard to race and ethnicity. Extracted data were further analyzed through direct comparisons and multivariable Cox regression models controlling for patient, tumor, and treatment characteristics. RESULTS: Unadjusted survival curves for all sinonasal carcinomas showed poorer disease-specific survival for black versus white patients (P = .02), which was eliminated after controlling for tumor characteristics (hazard ratio: 1.02, P = .86). Specifically for sinonasal squamous cell carcinoma, significantly poorer disease-specific survival was found for both black (P = .01) and Hispanic (P = .01) patients as compared with white patients. Similarly, when controlling for tumor characteristics, the disease-specific survival disparity was eliminated for black (hazard ratio: 0.93, P = .59) and Hispanic patients (hazard ratio: 1.01, P = .94). CONCLUSION: Black race is a risk factor for poorer disease-specific survival when all sinonasal histologic subtypes are examined together. Specifically for sinonasal squamous cell carcinoma, both black race and Hispanic ethnicity are risk factors for poorer disease-specific survival. When tumor characteristics are controlled for in this cohort, the survival disparity is eliminated, demonstrating that the disparity can be accounted for exclusively by more advanced disease at presentation, opposed to the more complex effect seen in other subsites of the head and neck.
