Paediatric Nasopharyngeal Carcinoma: An 8-Year Study from a Tertiary Care Cancer Centre in South India

Nasopharyngeal carcinoma (NPC) accounts for less than 1 % of all paediatric cancers. Advances in imaging, radiation delivery, chemotherapy and improvement in multidisciplinary care have resulted in drastic changes in the outcome of this disease. Since NPC is extremely rare in paediatric population and there is paucity of data in Indian patients, we conducted the present study to analyze the outcome of paediatric NPC. Eighteen patients aged 18 years or less, who had pathologically proven diagnosis of NPC and had received treatment at our institute from 2003 to 2010 was included for analysis. These patients were treated with radiotherapy and chemotherapy. Event free survival, local and systemic relapse and progression were analysed. These outcomes were correlated with age, radiation dose and the stage of disease. Majority of patients presented with advanced stage and poor histological grade (94.4 % had WHO Type III disease). The median follow up was 38 months (range 3–91 months). The estimated event free survival at a follow up of 5 years was 64.28 %. Distant metastasis at presentation and lower radiation dose were predictive of poor outcome. Paediatric NPC usually presents in an advanced stage. Our results are comparable to studies which have used only chemoradiotherapy, are far inferior to studies which have used chemoradiotherapy and adjuvant immunotherapy. Larger prospective studies are required to define the role of adjuvant immunotherapy, the optimum dose and schedule of chemoradiotherapy and role of new agents like cetuximab in Indian paediatric patients.
