Description
Objectives: Nasopharyngeal carcinoma is a rare malignancy in children. The aim of this study was to provide analysis of children with nasopharyngeal carcinoma treated in a single institution.
Methods and materials: Between 1999 and 2016, fourteen pediatric patients with a diagnosis of undifferentiated nasopharyngeal carcinoma were treated in our institution, and the patients' clinical characteristics, treatment modality, outcome, and toxicity were analyzed.
Results: The median age at diagnosis was 15,5 years. The gender ratio was 1:1. The majority of patients had regionally and/or locally advanced tumors and one had bone metastases at the time of diagnosis. All patients received chemotherapy before radiotherapy, with partial response in thirteen patients and complete response in one. Radiation dose to the primary tumor and involved cervical lymph nodes was 55-60 Gy, uninvolved cervical and supraclavicular regions received prophylactic radiation with dose of 45-50 Gy. Ten patients received adjuvant chemotherapy. Three-year progression-free rate and three-year overall survival (OS) rates were 75% and 73% respectively. Five-year progression-free rate was 65% and OS 63% respectively, and after ten years progression-free rate and OS remained the same. At the end of follow-up period, ten patients were alive, and four died. All of the patients that had distant metastases died. Most common late complications were skin fibrosis and xerostomia.
Conclusions: Multimodal therapy of children with nasopharyngeal carcinoma is associated with long-term survival. It is expected that further advances in the management of these patients, with improved radiotherapy and chemotherapy, will reduce acute and late toxicity and improve quality of life of treated children.
