title: [Malignant tumors of the nasal cavity and paranasal sinuses (author's transl)].
abstract: Therapeutic results from 134 cases with malignant tumors of the nasal cavity and paranasal sinuses are reported. Retrospective classification based on clinical and roentgenological findings was possible in 121 cases. 49 patients underwent primary radiation treatment by 60Co-teletherapy, 46 were exposed to postoperative irradiation. The mean 2-year survival rate considering all stages and all kinds of malignant tumors amounts to 52%, the 5-year survival rate to ca. 32%. The 5-year survival rate obtained by means of curative tumor doses was 59%. Recurrences of the tumor appeared in 58 cases (43%), most of them in the course of a year. The therapeutic control of local tumor disease and the possibilities of an early detection of recurrences, improved with the help of new diagnostic methods, must therefore be regarded as the essential problems. No generally approved clinical classification of tumors of the nasal cavity and paranasal sinuses is available as yet, and the comparison of therapeutic results from different authors thus is difficult.
