[Results of therapy in cases of tumors of the nasal cavity and paranasal sinuses in relation to different tumor classifications (author's transl)].

The primary findings in 128 patients with malignancies of the nasal cavity and the paranasal sinuses were classified by 4 tumor classifications. The survival times and the rates of recurrences in relation to the stage of tumor were compared. Mostly cancers of advanced stages T3 and T4 with bad prognosis were treated: only 35% of the examined patients survived longer than 5 years. There was no obvious difference in the results of therapy in tumor cases T3 and T4 in relation to the different tumor classifications.
