Brachytherapy in Combination with Function-Preserving Surgery of Cancer of the Paranasal Sinus Backgrund: Prognosis of patients with advanced/recurrent cancer of paranasal sinuses and orbit with infiltration of the skull base is very bad. Radical surgery does not improve prognosis. A disadvantage of the radical surgery is the functional loss and the residual cosmetic defect. We present the results of a function-preserving surgery in combination with interstitial, image adapted brachytherapy (IABT) for the treatment of these cancers. Methods and Patients: Ten patients with paranasal sinus cancer and 16 patients with sarcomas (n=26) were retrospectively analysed. After a maximum tumor resection (mostly R1R2 resections), 212 flexible afterloading plastic tubes were implanted. The postoperative IABT total dose was 1025 Gy in 2.5 Gy fractions twice daily fractions for 5 days. Results: In all cases the eye was obtained without functional damage. The IABT was well tolerated. The visual and cosmetic results were satisfactory. Postoperative complications occurred in 7 out of 26 cases without a serious long-term adverse event. Significant radiation-induced complications were found in patients with orbital or skull base involvement. The three years overall survival was 60% for rhabdomyosarcoma, and 33% for the paranasal sinus cancers. Conclusions: These results show that a combined treatment of function-preserving surgery and a IABT is a feasible, successful and well-tolerated option for curative, salvage and palliative therapy for selected patients with advanced or recurrent carcinoma of the paranasal sinuses and orbit.
