The expression of matrix metalloproteinases (MMPs) in epithelial-myoepithelial salivary gland carcinoma has not been studied previously.
Immunohistochemistry for MMP-1, -7, -9, -13, Ki-67, and HER-2, as well as HER-2 gene amplification by silver enhanced in situ hybridization was performed in a series of 12 paraffin-embedded histopathologic samples of patients from Canada and Finland.
A positive MMP-13 (p = .0022), higher MMP-13 (p = .0274), and higher MMP-9 (p = .0274) index (multiplication of staining intensity by percentage of the positive cells) predicted better overall survival. In disease-specific analysis, higher MMP-9 index (p = .0327) predicted better survival. A higher volume corrected index (VCI) of Ki-67 (p = .0339) predicted worse disease-specific survival. In 1 patient, HER-2 oncogene amplification was observed.
MMPs and Ki-67 may have prognostic impact in epithelial-myoepithelial carcinoma.
先前尚未研究过上皮-肌上皮涎腺癌中基质金属蛋白酶(MMPs)的表达。
对来自加拿大和芬兰的 12 例石蜡包埋组织病理学样本进行 MMP-1、-7、-9、-13、Ki-67 和 HER-2 的免疫组织化学检测,以及通过银增强原位杂交进行 HER-2 基因扩增。
阳性 MMP-13(p=0.0022)、更高的 MMP-13(p=0.0274)和更高的 MMP-9(p=0.0274)指数(染色强度与阳性细胞百分比的乘积)预测总体生存率更好。在疾病特异性分析中,更高的 MMP-9 指数(p=0.0327)预测生存率更好。Ki-67 的体积校正指数(VCI)更高(p=0.0339)预示着疾病特异性生存率更差。在 1 例患者中观察到 HER-2 致癌基因扩增。
MMPs 和 Ki-67 在上皮-肌上皮癌中可能具有预后影响。
