RESUMO
OBJECTIVE: To evaluate the expressions and significances of CD147, OPN and MMP-2 in oral squamous cell carcinoma (OSCC). METHODS: The expressions of CD147, OPN and MMP-2 were detected by immunohistochemical method (SP) in 35 cases of ()SCC. The relationships between the expressions of CD147, OPN and MMP-2 and clinic histopathologic parameters of OSCC were analyzed. RESULTS: The expression rates of CD147, OPN and MMP-2 in OSCC tissues were 65.71%, 71.43% and 68.57% respectively. The expressions of CD147, OPN and MMP-2 were positively correlated with tumor histopathologic type, clinical stage and lymph node metastasis (P < 0.05), but not correlated with age, gender and the location of tumor (P > 0.05). The positive correlations were found among the expressions of CD147, OPN and MMP-2 (MMP-2 and CD147, r = 0. 653; MMP-2 and OPN, r = 0.540; CD147 and OPN, r = 0.381; P < 0.05). CONCLUSION: The expressions of CD147, OPN and MMP-2 increase in OSCC and may be the potential predictor of the malignant degree of OSCC.
