Abstract
PURPOSE: To evaluate treatment results and prognostic factors, pediatric patients with nasopharyngeal carcinoma were reviewed. MATERIALS AND METHODS: Thirty-two patients at the age of 16 and younger were treated for nasopharyngeal carcinoma. One patient had WHO type I, 15 had WHO type II, and 14 had WHO type III histology. All patients were treated with radiotherapy, median dose to nasopharynx and involved nodes was 70 Gy (range 60-70.4 Gy), three patients received intracavitary booster dose of 24 Gy in three fractions, 12 patients were also given from two to four courses of platinum based neo-adjuvant chemotherapy. RESULTS: Twenty-three patients are alive and well with a median follow-up of 107 months. Ten and 15 years loco-regional control (LRC) and overall survival (OS) rates were 82.5, 68.7 and 72.7, 62.4%, respectively. Patient age, size of the lymph node and prolongation of overall external radiotherapy time were found to be the prognostic factors in univariate analysis, however the only factor remained significant after multivariate analysis was the size of the lymph node on LRC. Almost all long-term survivors experienced moderate to severe complications yielding complication free survival rate of 10.9% at 15 years.
