Purpose:
The incidence of nasopharyngeal carcinoma in Germany is relatively low in comparison with certain regions in south-east Asia. However, standardised therapeutical regimes are required in the treatment of these tumours.
Methods:
Between August 1990 and December 1997, 25 patients with stage III and IV nasopharyngeal carcinoma received an accelerated and hyperfractionated radiotherapy with concurrent chemotherapy (5-FU and mitomycin C). The primary tumour and positive lymph nodes received a total dose of 72 Gy over a period of 6 weeks. In the first 3 weeks, irradiation fields were treated five times per week with 2 Gy per fraction. Thereafter, treatment was accelerated, giving two daily fractions of 1.4 Gy. Salvage surgery was offered for residual lymph node disease after radiotherapy.
Results:
The overall response rate defined as complete and partial response of the primary was 100%. Sixteen of the 25 patients were still alive and were free of any evidence of tumour recurrence or distant metastases at a mean follow-up period of 34 months (range 7-95 months). Six patients received salvage surgery. Only one of these six patients had histologically proven evidence of vital tumour. No severe late complications such as blindness or temporal lobe necrosis were observed.
Conclusions:
The presented data are promising and show that the combination of hyperfractionated accelerated radiotherapy and chemotherapy is feasible and effective.
