A group of 113 patients irradiated for parotid tumor was studied retrospectively. Sixty-two patients were irradiated after superficial parotidectomy or enucleation of a pleomorphic adenoma. None of them had a recurrence after 5-15 years. Sixteen patients were irradiated postoperatively after surgery for a recurrence of pleomorphic adenoma. Only one of them had developed a recurrent tumor. Thirty-five patients with a malignant parotid tumor were treated by irradiation, 22 after surgery and 13 after biopsy only. Patients with a low malignancy tumor (10/11) and adenoid cystic carcinoma (6/12) responded better than patients with a high malignancy carcinoma (2/12). A tumor larger than 4 cm, facial nerve palsy, lymph node metastasis, and inoperability indicate a poor prognosis. With high dose radiotherapy it is possible to treat inoperable tumors successfully. Adenoid cystic carcinomas can respond well to irradiation alone.43 references.
