RESUMO
BACKGROUND: Sinonasal cancers are rare and comprise <1% of all malignancies. This study describes incidence and survival in sinonasal carcinomas in Denmark from 1980 to 2014. METHODS: All patients registered in the Danish Cancer Registry in the period were included. Age-adjusted incidence rate, average annual percentage change, and relative survival were calculated. Age-period-cohort models were constructed. RESULTS: 1,720 patients with sinonasal carcinoma (median age 67 years, 63% males) were identified. There was no significant change in age-adjusted incidence; 0.70 in 1980 to 0.43 per 100,000 in 2014 (p > .05). Relative 5- and 10-year survival were 52% and 40% for men, 58% and 42% for women. An increase in 5-year survival from 1980 to 2014 from 46% to 65% (p < .05) was found. Nasal carcinomas had a significantly better relative survival compared to sinus carcinoma, as did squamous cell carcinomas when compared to neuroendocrine malignancies. CONCLUSION: In Denmark between 1980 and 2014, the incidence of sinonasal carcinomas has been stable and the relative survival has increased significantly.
