구강설 편평세포암종에서 E-Cadherin과 Matrix Metalloproteinase-2의 발현 = Expression of E-Cadherin and Matrix Metalloproteinase-2 in Squamous Cell Carcinoma of the Oral Tongue

다국어 초록 (Multilingual Abstract)

Background and Objectives：To evaluate the relationship of the clinicopathologic findings in squamous cell carcinomas of the (MMP-2) by immunohistochemical stain. Materials and Method：Twenty-five patients with squamous cell carcinomas of the oral tongue were clasified as their tumor stage, lymph node metastasis and histopathological grade and their parafin-embedded surgical specimens were investigated by imunohistochemical analysis using monoclonal E-cadherin antibody and MMP-2 antibody. Results：There was not any significant corelation betwen the expresion of E-cadherin and the tumor stage (p>0.05), but it showed significantly reduced expression of E-cadherin in moderately or poorly differentiated carcinoma (p= 0.034). The expression of MMP-2 increased significantly with respect to the metastasis of the cervical lymph node in early carcinoma (p= 0.045) but it was not corelated with primary tumor size or histological diferentiation (p>0.05). We cannot find any inverse relationship Conclusion：The expresion of E-cadherin and MMP-2 may be related the disease processes of squamous cell carcinomas of the oral tongue and will provide the possibility of the its biochemical parameters.
