Long-term survival of patients with paranasal sinus carcinoma.

The survival rate for all patients with a squamous cell carcinoma of the paranasal sinuses (n = 77) diagnosed in 1960-1985 in a population of approximately 1 million inhabitants was analysed without any selection of cases. This population is geographically restricted to the most northern part of Sweden. The 5-year survival rates of patients with T3 and T4 carcinomas were 42 and 14%, respectively (corrected survival), and the 10-year survival rates were 40 and 14%, respectively. In patients with tumours which initially were considered as resectable, the optimal treatment modality was a combination of radiotherapy and surgery.
