We reviewed 141 cases of paranasal sinus tumors treated at Karolinska Hospital from 1960 to 1980. Of these tumors, 100 were located in the maxillary sinus, 32 in the ethmoidal sinuses, 8 in both the ethmoidal and maxillary regions, and 1 in the sphenoidal sinus. The male-to-female ratio was 2.1 to 1. Squamous cell carcinoma and adenocarcinoma were the most frequent types of tumors (55% and 13%, respectively). Treatment included surgery, irradiation, or both. The 5-year survival rate was 34% for squamous cell carcinomas and 64% for adenocarcinomas. When compared to a previous material of patients treated at the same hospital from 1940 to 1950, the proportion of poorly differentiated squamous cell carcinomas had increased significantly. The age-adjusted incidence rate decreased from 1.2 to 0.4 for male patients and from 0.7 to 0.3 for female patients between 1960 and 1980. We conclude that the incidence of malignant paranasal sinus tumors has decreased, and that squamous cell tumors now seem to be generally less differentiated than they were 50 years ago.
