title: Cancer of the paranasal sinuses and nasal cavities. Part II. Results of treatment.
abstract: Part I of this account of a large consecutive series of 561 patients with cancer of the paranasal sinuses and nasal cavities treated at the Royal Marsden Hospital reveals some significant clinical and radiological features. The histopathology of every case has been carefully reviewed by one pathologist. Carcinoma was found to account for almost 80 per cent of tumours. An account is given of treatment methods in present use. End-results are reported in Part II of the paper and demonstrate that patients with sinus cancer receiving combined treatment in one centre have a better prognosis than when it is given in two or more hospitals. The discussion also concentrates on the use of main treatment methods and emphasizes some advances in surgical techniques. The value of initial cytotoxic chemotherapy is unproven but may offer some further advantage in prognosis. Precise comparison with the results of other series is not possible owing to lack of agreement on classification, variable case selection and differing treatment techniques.
