Abstract
A clinical study was performed on 139 patients with major salivary gland tumors initially treated in our hospital from 1991 to 2000. Benign tumors were observed in 117 patients (male: 54; female: 63) and malignant tumors in 22 patients (male: 12; female: 10). The five-year survival rate was 43.4% in the whole malignant tumor group, 80.0% in the stage I, II group and 12.7% in the stage IV group. The factors influencing prognosis were stage IV status, local pain, and facial palsy. Our findings suggested that postoperative radiation and/or chemotherapy are useful.
