Hpa、uPA 在分化型甲状腺癌组织中表达的临床意义

Expression and clinical significance of Hpa and uPA in thyroid carcinoma

目的：研究乙酰肝素酶（ heparanase，Hpa）、尿激酶纤溶酶原激活剂（ urokinase type plasmino-gen activator，uPA）在甲状腺癌组织中的表达与淋巴结转移的关系。方法采用免疫组化SP法检测113例甲状腺癌及134例良性甲状腺结节组织中Hpa、uPA蛋白的表达情况，分析Hpa、uPA蛋白在甲状腺癌中表达及其临床意义。结果 Hpa、uPA在甲状腺癌及良性甲状腺结节组织中表达阳性率分别为82.30％、89.38％和16.42％、11.19％，甲状腺癌组织中Hpa、uPA的表达高于良性甲状腺结节（P＜0.001）。在甲状腺癌有、无淋巴结转移组Hpa、uPA蛋白表达阳性率分别93.94％、100％和65.96％、74.47％，甲状腺癌组织中有周围淋巴结转移组Hpa、uPA的表达高于无周围淋巴结转移组（ P＜0.001）。 Hpa、uPA在甲状腺癌组织中的表达成正相关性（r＝0.437，P＝0.021）。结论 Hpa、uPA检测在甲状腺良恶性肿瘤鉴别诊断、淋巴转移方面有一定的临床价值。

Objective To study the relationship between heparanase（ Hpa） , urokinase type plasminogen activator（ uPA） expression and lymph node metastasis in thyroid carcinoma.Methods Immunohistochemieal SP method was used to analyze the expression of Hpa and uPA in 113 cases of thyroid carcinoma and 134 cases of be-nign thyroid nodules.The expression of Hpa and uPA in thyroid carcinoma and its clinical significance were ana-lyzed.Results The positive expression rate of Hpa and uPA in thyroid carcinoma and benign nodular thyroid tis-sue were 82.30%,16.42%and 89.38%, 11.19%.The positive expression rate of Hpa and uPA in carcinoma tissues with lymph metastasis and without metastasis were 93.94%,100% and 65.96%,74.47%.Expression of Hpa and uPA in thyroid carcinoma group was significantly higher than that of benign thyroid nodules group（ P〈0.001） .The rate of positive expression in lymph metastatic tissues were significantly higher than those in tissue without metastasis（ P〈0.001） .Hpa and uPA expression in thyroid carcinoma tissues was positively correlated（ r=0.437, P=0.021）.Conclusion The expression of Hpa and uPA is closely related with the occurrence and metastasis of thyroid carcinoma.
