Abstract
The aim of this study was to determine the expression of matrix metalloproteinase 2 (MMP-2) and tissue inhibitors of matrix metalloproteinase 2 (TIMP-2) and the MMP-2/TIMP-2 expression ratio in salivary gland tumours (SGTs). Forty-three FFPE SGTs were prepared for antibody processing to MMP-2 and TIMP-2. Two investigators utilizing Sinicrope’s method scored the uptake of immuno-stains. Cytoplasmic staining was considered as positive. Data was analysed using SPSS version 20. The significance level was set at p < 0.05. In benign SGTs, the mean score for MMP-2 was not significantly lower than that of TIMP-2 (p = 0.37). However, the mean scores for MMP-2 stain intensity and proportion were significantly higher in malignant than benign SGTs (p = 0.01 and p = 0.02 respectively). There was no significant difference in the mean MMP-2/TIMP-2 expression ratio of the malignant SGTs according to histological grade and histogenesis (p = 0.4 and p = 0.19 respectively). The MMP-2/TIMP-2 expression ratio has a higher prognostic value than the separate expressions of MMP-2 and TIMP-2.
