The authors conducted a retrospective study on 99 patients with malignant tumors of the major salivary glands, who had been treated by radiotherapy between 1976 and 1986: 86 cases of parotid tumors and 13 cases of submandibular gland tumors. Only 28 tumors (28%) were T1-T2, N0-N1. Local control, 3-5 and 8-year survival rates, and complications were considered. Radiation therapy alone was performed on 19 patients (19%), while combined surgical and radiation therapy was performed on 80 patients (80%). The results of radiation therapy alone and combined with surgery are discussed. Loco-regional disease control was obtained in 9 out of 19 patients (47%) by irradiation alone, and by combined irradiation and surgery in 60 out of 80 cases (75%). Distant metastases developed in 23 out of 99 patients (23%). Loco-regional metastases were the most frequent cause of death (20 out of 55 cases: 36%). Severe complications were extremely rare. The results demonstrate not only the advantages of combined treatment but also the value of radiotherapy alone in the treatment of tumors of the major salivary glands.

Abstract
The authors conducted a retrospective study on 99 patients with malignant tumors of the major salivary glands, who had been treated by radiotherapy between 1976 and 1986: 86 cases of parotid tumors and 13 cases of submandibular gland tumors. Only 28 tumors (28%) were T1-T2, N0-N1. Local control, 3-5 and 8-year survival rates, and complications were considered. Radiation therapy alone was performed on 19 patients (19%), while combined surgical and radiation therapy was performed on 80 patients (80%). The results of radiation therapy alone and combined with surgery are discussed. Loco-regional disease control was obtained in 9 out of 19 patients (47%) by irradiation alone, and by combined irradiation and surgery in 60 out of 80 cases (75%). Distant metastases developed in 23 out of 99 patients (23%). Loco-regional metastases were the most frequent cause of death (20 out of 55 cases: 36%). Severe complications were extremely rare. The results demonstrate not only the advantages of combined treatment but also the value of radiotherapy alone in the treatment of tumors of the major salivary glands.
