title: Recurrences from malignant parotid salivary gland tumors.
abstract: The clinical course of 130 patients treated for malignant parotid tumors at the three institutions have been reviewed. Fifty-six of these 130 patients developed recurrences following their primary treatment by a surgical procedure. There were a total of 109 recurrences among these 56 patients. The average number of recurrences was two per patient. The average survival from first recurrence was 3.7 years, with the median survival 2 years. The range of survival was 0.5 to 17 years. Once recurrence developed, treatment was by surgery, radiation therapy, chemotherapy, or a combination. Of 56 patients with recurrence, 33 are dead and 9 patients are alive with disease. Fourteen patients are alive and well with no evidence of disease. These NED patients had an average number of 1.6 recurrences and a median survival to date of only 3 years. Our study indicates that for the majority of patients who develop recurrence, survival is relatively short and treatment is usually ineffective in three of four patients. The authors conclude that after a surgical procedure for malignant salivary gland tumors, a trial of wide field postoperative radiation therapy to high dose should be considered as part of the initial treatment.
