骨桥蛋白在卵巢上皮癌组织中的表达及其与预后的关系

目的 探讨卵巢上皮癌组织中骨桥蛋白的表达及其与预后的关系.方法 应用免疫组织化学法测定骨桥蛋白在64例卵巢上皮癌组织、20例卵巢良性肿瘤组织及10例卵巢正常组织中的表达,分析其表达与临床病理分期及其与预后的关系.结果 64例卵巢上皮癌患者组织中骨桥蛋白表达阳性52例,骨桥蛋白在卵巢上皮癌组织中的阳性表达率81.3%(52/64)明显高于卵巢良性肿瘤15.0%(3/20)]及正常卵巢组织10.0%(1/10)],差异有统计学意义(P均<0.01).骨桥蛋白的表达与卵巢上皮癌的分期、分化及有无腹水和淋巴结转移有关.骨桥蛋白阴性表达组患者的总生存时间(2年生存率为91.7%,3年生存率为83.3%)明显高于骨桥蛋白阳性表达组(2年为67.3%,3年为55.6%).结论 骨桥蛋白与卵巢上皮癌的发生、发展及其预后密切相关.

Expression of osteopontin in epithelial ovarian cancer tissue and its relation to the prognosis

Objective To investigate the expression of osteopontin ( OPN) in epithelial ovarian cancer tissue and its prognostic value. Methods The immunohistochemistry method was used to detect the expression of OPN in 64 cases of epithelial ovarian cancer tissue, and 20 cases with ovarian benign tumors and 10 normal ovarian tissues as well. The relationship between the OPN expression and clinical pathological characteristics and its prognostic value were analyzed statistically. Results The positive expression of OPN case was confirmed in 52 cases in 64 epithelial ovarian cancer. The expression level of OPN in epithelial ovarian cancer tissue was significantly higher than that in benign ovarian tumor and normal control (P <0. 01). The OPN expression in epithelial ovarian cancer tissues was associated with the pathological grading, lymphatic metastasis and production of ascites. The survival time is longer in OPN negative patients than the positive group. Conclusions OPN plays an important role in the tumorgenesis and development of epithelial ovarian cancer and correlates with its prognosis.
