Treatment results in a group of 70 patients with salivary gland tumors were analyzed. Prognosis appeared to correlate with both clinical stage and malignancy of tumors. In patients irradiated postoperatively because of nonradical operation, a higher 5-year survival rate was achieved than in patients after radical surgery. It is suggested that postoperative radiotherapy improves treatment results in patients with T2 and T3 lesions. In unresectable cases (T4) a 13 % 5-year survival was achieved. In patients with highly malignant cancers a high incidence (41.9 %) of distant metastases was observed during the 5-year follow-up.
