[Therapy result of malignant tumors of the paranasal sinuses in patients treated at the metropolitan onco-radiologic centre of Budapest. Period under review: 1946-1974 (author's transl)].

A report is given on the therapy results of 301 patients with ethmoidomaxillary tumors treated at the Metropolitan Onco-Radiologic Centre of Budapest between 1946 und 1974. Most of these patients were in an advanced stage when the first diagnosis was established. The five-year survival rate of all stages was 27%, which does not strongly differ from the average value of 30% mentioned in literature. The five-year survival rate of the patients submitted to a combined surgical and radiologic treatment was 33%, that of the patients treated by irradiations only was 16%. 81 patients received an intracavitary brachycurietherapy after having undergone a non-radical operation. The five-year survival rate of this group was 38%. The intracavitary brachycurietherapy is most favorable and should always be applied in case of this not very radiosensible, often even radioresistant tumor.
