Sinonasal malignancies (SNM) are rare and the prognosis is generally poor. Recently, a change in incidence for SNM has been reported. In this study, we investigated population-based trends for SNM in Sweden. Methods: We identified 3,221 patients from the Swedish National Cancer Registry diagnosed with primary malignancies arising from the nasal cavity, paranasal sinuses, or both, during the period 1960 through 2010. Incidence, gender and age, anatomical sites and relative survival were investigated. Results: The incidence for SNM decreased except for sinonasal malignant melanoma (SNMM) and adenoid cystic cancer (even though a very small group) during the study period. More than 50 % of the malignancies involved the nasal cavity. The five-year relative survival was highest for adenoid cystic cancer followed by adenocarcinoma. SNMM and undifferentiated carcinoma had the poorest prognosis. Conclusion: We found that the incidence for SNM has decreased during the study period 1960 through 2010, except for SNMM that has increased.
