100 patients with destruction of skull base in nasopharyngeal carcinoma, confirmed by pathology and CT scanning before radiotherapy, were analysed. It showed that the primary characteristics of skull base destruction are headache and cranial nerve involvement. Although the destruction of skull base showed evident manifestation in TNM classification, it can be inferred that the erosion development probably took place within 1-6 months. Comparing the CT scanning with X-ray submento-vertical view, the result indicated that the erosions of the various positions of the skull base and the invasion of paranasal sinus, cavernous sinus and orbit were clearly displayed by CT scanning but only 23% was discovered by X-ray. There was significant difference between CT scanning and X-ray, and CT scanning had more advantages. The relation between the erosion of the skull base and the invasion of parapharynx space and the metastatics of the cervical nodes were also discussed.

Nasopharyngeal carcinoma is a very rare disease of children. Between 1992 and 2005, 8 male and 2 female patients [ages ranging from 12 to 17 years,] were treated in our institution. The histopathologies were all undifferentiated type (WHO Type III). Of the ten patients, one was T2, five were T3, and four were T4, respectively (TNM system of the American Joint Committee for Cancer Staging). Eight patients had node metastases, 6/8 had bilateral and 4/8 had nodes larger than 6 cm. The main symptoms at diagnosis were neck mass followed by nasal, aural symptoms, cranial nerve palsy and headache. Four patients received radiotherapy only, while six patients received cisplatin-based concomitant chemoradiotherapy. The mean irradiation doses to the primary sites were 7200 cGy. Two patients developed early systemic relapse and died one year and 4 months, respectively, after relapse. After a median follow-up of 30 months, the event-free survival and overall survival were 70% and 75%, respectively. Although the sample size was small, it seemed that the patients had a good chance of survival in spite of advanced stage. However, late morbidity was a concern.

Malignant tumours with nasopharyngeal primary location are relatively rare in children. One of the most frequent paediatric neoplasms in this region is the undifferentiated nasopharyngeal carcinoma tumour (UCNT). These tumours are usually revealed by nasal obstruction, headache or cervical nodal involvement. The nasopharyngeal mass can be discovered during an ear-nose and throat examination and confirmed after medical imaging investigation. Diagnostic is obtained by nasopharyngeal mass or cervical nodal biopsy. This tumor has a high chemo and radio-sensibility in children. Irradiation of the cavum and the nodes areas remains as the reference treatment of this disease. Most paediatric protocols add chemotherapy to radiotherapy. The value of concomitant or adjuvant chemotherapy is still debated in paediatric population. It was shown that the T and N staging at diagnosis determined by the classification TNM is a major prognostic factor. Due to the importance of the loco-regional sequelae after irradiation and the satisfactory global prognosis, the actual trend is a decrease in the total dose of irradiation delivered, particularly for patient with a good response to first chemotherapy. This article sheds light on the particularities of UCNT in paediatric patients.
