Biologically aggressive papillomas of the nasal cavity: the role of radiation therapy.

Five patients were irradiated at the University of Florida for advanced and/or recurrent papillomas of the nasal cavity and paranasal sinuses from December 1969 through December 1981. Three patients were irradiated either before or after resection and two patients were treated with radiation therapy alone. Two patients had pure inverted papilloma, one patient had inverted papilloma associated with a focus of squamous cell carcinoma, and two patients had cylindrical cell papillomas. Four patients are alive and continuously disease free at 3, 3, 4, and 11 years following treatment. One patient died of intercurrent disease nine years following treatment without evidence of recurrent tumor.
