ABSTRACT Aim To evaluate the expression of laminin in various grades of oral squamous cell carcinoma (OSCC) in order to determine whether this protein can be used as a marker for early detection and elucidation of oral cancer. Materials and methods Immunohistochemical staining for laminin was done on 60 selected archival blocks of histopathologically diagnosed cases of primary OSCC and the laminin expression was compared between the different histopathological grades of primary OSCC. The statistical analysis was performed by using Chi-square (÷ square) test and Gaussiantest with a probability of p < 0.05 was considered as significant. Results It was observed that laminin expression decreased with tumor progression which may be correlated to the tumor aggressiveness. Conclusion There was a gradual decrease of laminin staining with decreasing cellular differentiation, with differentiated lesions showing a more conspicuous staining of basement membrane glycoprotein than less differentiated lesions. Clinical significance An understanding of how the extracellular matrix influences tumor development and invasion is fundamental in the development of new prognostic indicators and treatment strategies for oral squamous cell carcinoma.

Aim: Survivin is a multifunctional protein chiefly involved in apoptosis and cell cycle regulation. Increased expression of survivin in tumors and fetal tissue determines its antiapoptotic activity. The aim of the study is to identify the immunoexpression of survivin in metastatic and nonmetastatic oral squamous cell carcinoma (OSCC) and also to evaluate and compare the expression of survivin in metastatic and nonmetastatic OSCC of buccal mucosa. Materials and Methods: In total, 40 histopathologically proven cases of OSCC, including 20 metastatic and 20 nonmetastatic cases, are selected. Among the 20 metastatic and nonmetastatic cases, 10 well-differentiated and 10 moderately differentiated squamous cell carcinoma cases were included and were subjected to immunohistochemical staining for survivin expression. The results were analyzed by SPSS version 11.5 using chi-square test. Results: The expression of survivin in metastatic and nonmetastatic tumors is 15%–70% and 15%–60%, respectively. When comparing the cases of moderately differentiated squamous cell carcinoma in metastatic and nonmetastatic tumors, 70% cases show moderate staining intensity. Conclusion: The survivin expression was comparatively high in metastatic OSCC. Also based on the aforementioned results, survivin expression was high in increasing grades of OSCC.
