Paranasal sinus malignancy--a retrospective analysis of treatment methods

A retrospective analysis has been made of all cancers of paranasal sinuses seen at the Cancer Control Agency in Vancouver during the years 1970 to 1978. The overall crude five year survival for all cases (49) was 46%. A combined treatment using irradiation and surgery in selected cases generated a five year survival rate of 74.4% as compared to 42.1% in cases receiving irradiation alone. The clinical presentation, staging, and the need for the individualization of treatment methods based on a realistic knowledge of the pathological extent of the disease are discussed.
