摘要: [摘要]
  目的  检测腮腺多形性腺瘤及恶性多形性腺瘤中COX-2与Survivin蛋白的表达情况,探讨COX-2、Survivin与腮腺多形性腺瘤发生、发展及恶变的相关性。
  方法  按照Seifert分型标准将多形性腺瘤标本分为4组。A组,基质丰富型20例;B组,其他型24例;C组,细胞丰富型22例;D组,恶性多形性腺瘤18例。采用免疫组织化学法检测各组COX-2和Survivin蛋白的表达情况,分析COX-2和Survivin蛋白的表达在腮腺良恶性多形性腺瘤生成及转归中的相关性。
  结果  COX-2蛋白于肿瘤细胞的细胞浆中阳性表达,偶尔于细胞膜和细胞核中阳性表达。C组和D组COX-2蛋白阳性表达率高于A组(P<0.05)。Survivin蛋白在腺管样导管上皮细胞及黏液样组织中阳性表达,于细胞浆和(或)细胞核中可见棕褐色颗粒状阳性表达。D组Survivin蛋白阳性表达率高于A组(P<0.05)。经Spearman相关性分析,COX-2与Survivin表达呈正相关(rs=0.560,P<0.01),Survivin表达水平越高的组织细胞中,COX-2表达水平增高。
  结论  COX-2、Survivin在腮腺良恶性多形性腺瘤中的表达存在相关性,为多形性腺瘤临床病理诊断提供了一定的理论依据,并可能成为新的生物标志物和治疗基因靶点。

Abstract: [Abstract]Objective〖HTSS〗 To investigate the relationship between COX-2 and survivin expression in the development and progression of malignant adenoma of the parotid gland, through detecting the expression of COX-2 and survivin protein in pleomorphic adenoma and malignant pleomorphic adenoma.
  〖WTHZ〗Methods〖HTSS〗According to the Seifert classification criteria, the pleomorphic adenoma specimens were divided into four groups: group A, 20 samples categorized as myxoid type nodules(predominance of intervening stroma); group B, 24 samples categorized as other type; group C, 22 samples categorized as cell-rich type nodules(predominance of epithelial cells); group D, 18 samples categorized as malignant pleomorphic adenoma. The expression of COX-2 and survivin in each group was detected by immunohistochemistry method, and the correlation between the expression of COX-2 and survivin in the occurrence and prognosis of parotid pleomorphic adenoma was analyzed.
  〖WTHZ〗Results〖HTSS〗COX-2 protein was expressed in the cytoplasm of tumor cells and occasionally in the cell membrane and nucleus. The positive expression rate of COX-2 protein in group C and group D was higher than that in group A(P<0.05). Survivin protein was expressed in glandular duct epithelial cells and mucoid tissues. Brown granules were found in cytoplasm or nucleus. The positive expression rate of Survivin in group D was higher than that in group A(P<0.05). Through Spearman correlation analysis, COX-2 expression was positively correlated with survivin expression(rs=0.560, P<0.01). The higher the expression level of survivin, the higher the expression level of COX-2.
  〖WTHZ〗Conclusion〖HTSS〗The expression of COX-2 and survivin in benign and malignant pleomorphic adenomas of the parotid gland is correlated, It provides a theoretical basis for the clinical pathological diagnosis of pleomorphic adenoma, and may become a new biomarker and therapeutic gene target.
