Two of eleven patients who underwent operation had local recurrence in soft tissue. There was no correlation between preoperative clinical or histological findings and local recurrence.6. Histological examination revealed that level I neck was at greatestrisk of nodal metastases, and often bilateral nodes were involved.7. Classical or modified radical neck dissection was undergone for node metastases. Out of 10 patients (15 necks) who had histologically proven neck metastases, one patient died of neck disease.8. 5-year survival rate was 63.6% in the patients who underwent the operation, and 83.3% in those who had interstitial irradiation.
