Abstract
Objective: Evaluate epidemiology of nose and paranasal sinus cancer in the city of São Paulo.
Method: This was a study based on population cancer registry data of São Paulo from 1997 to 2006. We extracted data of 628 patients (CID-10 C30, C31.x) from a total of 388.950 diagnosed with cancer among all tumors. We aggregated data into the morphologic groups according to ICD-O.
Results: The overall estimated incidence of nose and sinus tumors was 0.6 out of 100,000 and it was higher in men (0.7/100,000 vs 0.5/100,000). They are more frequent among fifth and eighth decades. The most common site was maxillary sinus (37.1%) followed by nasal cavity (33.3%). Isolated diagnosis of other sinus cancer was very rare and the most common was from ethmoid sinus (2.5%) The most common morphologic groups were squamous cell (followed by adenoid cystic carcinoma and esthesioneuroblastoma). The epidemiology of each site and each morphology were analyzed in detail.
Conclusion: Sinonasal cancers in São Paulo have an incidence comparable to described previously. The analysis of sinonasal cancers from reliable population based registry was not commonly reported and this information can provide us more knowledge about this disease, besides the large case series of large health services.
