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.
Key words : salivary gland tumor, malignant tumor, prognosis
