title: Analysis of adenoid cystic carcinoma treated by radiotherapy.
abstract: The records of 41 patients with adenoid cystic carcinoma of the head and neck region who had been treated with radiotherapy were reviewed. Local control was achieved in 72.3% in the cases with primary lesions at 5 years. The prognosis for tumors that arose in the major salivary glands was better than that for tumors that arose in the minor salivary glands; however, the difference was not statistically significant. In the minor salivary glands, early-stage tumors were well controlled with the use of radiation therapy alone. In spite of the high local control rate, the disease-free survival rate of the patients at 10 years was only 20.8%. Lung metastasis determined the prognosis.
