| Summary: | Background and Objectives: Survivin is an inhibitor of apoptosis protein. It is involved in the modulation of the cell death and cell division process. Alterations in the expression of Survivin have been reported in several inflammatory, premalignant, and malignant lesions. Hence, the objectives of the present study were to compare the expression of Survivin with respect to the degree of dysplasia in oral leukoplakia (OL) and to evaluate the expression of Survivin with respect to different histopathological grades of oral squamous cell carcinoma (OSCC).
Materials and Methods: Neutral-buffered, formalin-fixed and paraffin-embedded biopsy specimens from 30 patients, each with OL and OSCC, were included in this study. The expression of Survivin was detected by immunohistochemistry. The scores obtained were subjected to Chi-square test.
Results: Survivin expression was detected in all grades of dysplasia and OSCC. Expression of Survivin was significant when compared with different degrees of dysplasia and different histopathological grades of OSCC (P < 0.05). A significant correlation was not found in immunostaining between dysplasia and OSCC groups.
Conclusion: Higher immunohistochemical scores were obtained with increased histopathological grades of OL and OSCC. High expression of Survivin may be related to malignant transformation in OL and poor prognosis in OSCC.
