Radiation therapy in inverted papillomas of the nasal cavity and paranasal sinuses.
OBJECTIVE
Between December 1969 and September 1989, a total of 10 patients with advanced and/or recurrent inverted or cylindrical cell papillomas were treated with irradiation at the University of Florida in Gainesville.


METHODS
Nine of 10 patients had 1 or more recurrences before they received radiation therapy. Three patients were treated with irradiation alone, and 7 patients received surgery and irradiation (preoperatively in 1 patient and postoperatively in 6 patients). Eight patients had inverted papillomas (3 with concomitant squamous cell carcinoma), and 2 patients had cylindrical cell papillomas.


RESULTS
Local recurrence developed in 4 patients at 1.5, 6.5, 12, and 13 years after treatment. No evidence of recurrence was observed in 6 patients at 7, 8.5, 8.5, 9, 9, and 20.5 years after treatment. Four patients died of intercurrent disease. No patient developed a malignant transformation. Significant complications of treatment included, in 1 patient, an area of bone exposure in the orbit that necessitated debridement.


CONCLUSIONS
Surgery is the primary treatment of this entity. Radiation therapy should be considered in patients with incompletely resectable lesions, multiply recurrent tumors, and tumors associated with malignancy.
