Abstract

Objectives: Salivary gland neoplasms are a diverse group of benign and malignant tumors with a wide range of biologic behaviors. The surgeon must understand the pathologic behavior of each tumor type to develop an appropriate treatment plan. The authors planned this study to evaluate our clinical experiences and establish a new treatment strategy. Materials and Methods: From Sep. 1997 to June 2001, 25 cases of major salivary gland tumors which were underwent surgery were evaluated retrospectively.
Results
20 cases were benign and 5 were malignant. Most(17) of benign cases were pleomorphic adenoma and they showed wide distribution in age. Also we experienced other benign such as warthin's tumor, oncocytoma. In malignant, there were 2 cases of carcinoma ex-pleomorphic adenoma, 2 cases of adenoid cystic carcinoma, and one lymphoma. In carcinoma ex-pleomorphic adenoma, one showed dismal prognosis in spite of multimodality and the other were recurrent to be salvaged.
Conclusion
We concluded that salivary gland neoplasms are challenging because of their relative infrequency, inconsistent classification, and highly variable biologic behavior. We need to establish new effective strategies with the regard of factors influencing survival.
