PURPOSE: To analyze 15 patients treated with radiation therapy for juvenile nasopharyngeal angiofibroma (JNA) between June 1975 and March 1996. MATERIALS AND METHODS: All patients had a 2.5-year minimum follow-up. All patients had advanced disease (Chandler stage III or stage IV); two thirds of the patients had intracranial extension. RESULTS: Local control after radiotherapy was obtained in 13 of 15 patients (85%). Two patients had local recurrences, and both were salvaged with surgery for an ultimate local control rate of 100%. Late complications included cataracts in 3 patients, delayed transient central nervous system (CNS) syndrome in 1 patient, and a basal cell carcinoma of the skin in 1 patient. Of 15 patients, 13 (85%) had a complete response (CR) on physical examination following radiation therapy. The median time to CR was 13 months (range, 1 to 39 months). Of 6 patients with residual disease in more than 24 months, 2 (33%) had a recurrence, whereas no patient achieving CR in less than 24 months experienced a recurrence. CONCLUSIONS: Radiotherapy is an effective treatment for advanced JNA. Tumor regression usually occurs slowly over several months. JNAs that are slow to regress (greater than 2 years) may have an increased risk of recurrence.
