Malignant tumours of the paranasal sinuses and nasal cavity. A series of 180 patients.

In a series of 180 malignant tumours in the paranasal sinuses and nasal cavity the largest groups comprised 90 epidermoid carcinomas, 25 adenocarcinomas, and 19 adenocystic carcinomas. The epidermoid carcinomas were classified according to various proposed methods. The planned treatment schedule for carcinoma was 57 to 60 Gy in 30 fractions over 42 days, followed 8 to 12 weeks later by radical surgery. In the group of 80 patients with epidermoid carcinomas treated with radical intention, the 5-year corrected survival was 42 per cent. The prognosis has been analysed against a number of parameters, and it is found that sex, tumour size, and histologic score are important but neither totally independent nor evenly distributed parameters.
