title: [Radiotherapy of nasopharyngeal tumor. Evaluation of personal results, consequences for irradiation technic].
abstract: In this paper we present our results of radiotherapy of thirty patients with nasopharyngeal tumour from 1960-1983. Before therapy, 19% of the cases were diagnosed as a T1 tumour, 57% of the patients showed a T3 or T4 tumour. In 24% of the patients, lymph node metastases could be recognised in pretherapeutic staging, whereas in 5% distant metastases were evident. In more than 50% of the cases tumour recurrence or metastases occurred within one year, in 47% of these patients there was local recurrence, in 35% lymph node metastases. The 5-year survival rate was 28%. Basing on an assessment of our results and considering the published data, we changed our radiotherapy technique to a large-field radiotherapy including the tumour region and the lymph vessels. The advantages of this technique and the possible side effects are discussed.
