The purpose of this study was to evaluate the role of survivin in various salivary gland tumors. For this study, total 18 cases of salivary gland tumors; 6 cases of benign and 12 cases of malignant tumors were used as experimental group. In benign tumors; pleomorphic adenoma, oncocytoma, and in malignant tumors; adenoid cystic carcinoma, mucoepidermoid tumor, high grade and low grade malignancy each, adenocarcinoma, acinic cell adenocarcinoma cases were included. And for the control group, fresh submandibular glands were attained from gnathosurgical specimen. All the specimens, experimental, control group were fixed in 10% neutral formalin solutions, embedded in paraffin, sectioned 5um or more in thickness, stained with the hematoxylin and eosin, mounted and examined under the microscope. For the immunohistochemical studies, all the specimens were activated with survivin monoclonal, and secondary antibodies as usual manners, and taken photos on various pathologic fields analysed with the image analysis system, and evaluated the positive and negative stained area in the tumors on each images and statistically analyzed with SPSS 15.0 program. Attained result as follows. In control group, in part, acini cells show positive reaction on the nuclei, negative on the all most of the cytoplasm, more intense reaction on the cytoplasm and nuclei on the serous demilune (47.33%). In experimental group, all the specimens show survivin positive reaction on the cytoplasm with/or without positive reaction on nuclei according to the tumors, in benign tumors; pleomorphic adenoma (63.48%), oncocytoma (56.31%), each and in malignant tumors; adenoid cystic carcinoma (87.6%), acinic cell adenocarcinoma (56.35%). adenocarcinoma (67.47%), mucoepidermoid carcinoma, low grade (70.76%). high grade (55.23%). Survivin expression shows higher in tumors compare to that on the control group (p<0.05), but between the malignant tumors no significant are not noted(p>0.005). Survivin expression is strongly related to the malignancy of salivary gland tumors.
