Backgroud and Objectives: Major salivary gland tumor is a rare disease with a largely unknown origin. And also corresponding to the diversity of histopathologic characteristics is an equally wide distribution of clinical behavior that makes treatment decisions difficult. The aim of this study is to analysis the clinical experience of our major salivary gland tumor and to suggest a guidline of management. Materials and Methods : We studied clinical manifestations and treatment results of 104 patients who were diagnosed as major salivary gland tumors. Tumor site, patient age and sex of the patients were analysed. Histopathologic diagnosis, treatment modality, lymph nodes metastasis, recurrence rate and 5-year survival rate were studied on malignant tumors. Results: 1) 48 patients were male and 56 patients were female. 2) Benign tumors were 79 cases. They consisted of 57 cases(72%) of parotid tumor, 22 cases(27%) of submandibular tumor. And pleomorphic adenoma was the most common benign tumor. 3) Malignant tumors were 25 cases and were consisted of 19 cases(76%) of parotid tumor, 4 cases(l6%) of submandibular tumor and 2 cases(8%) of sublingual gland tumor with high-grade mucoepidermoid carcinoma as the most common cause. 4) In the malignant tumors, the number of stage I, II tumors was 14 and that of stage III, IV tumors was 11. Neck node metastasis was noted in 8 cases. 5) 8 cases of malignant tumor were died and all of them had high-grade malignancy. And they were dead before 17 months from the time of diagnosis. 6) Mean survival duration in the malignant salivary gland tumor was 56 months. 7) High-grade malignancy had a 5-year survival rate of 57.9%. A 5-year survival rate of TI, T2 patients was 92.9% and that of T3, T4 patients was 36.4%. That of patients who had neck node metastasis was 37.5% and that of those who had tree neck was 82.4%. Conclusion: The results of this study suggest that the survival rate is dependent on the tumor size, lymph node matastasis and histologic grade. And also the early diagnosis and radical surgery result in the increased survival rate and are effective for prevention of the tumor recurrance.
