摘  要:目的探讨与张力蛋白同源的第10染色体丢失的磷酸酶基因(PTEN)在卵巢上皮性癌组织中的表达,分析其与临床病理参数间的关系,并分析其与卵巢上皮性癌患者预后的关系。方法应用免疫组织化学方法,检测10例正常卵巢组织(正常卵巢组),20例卵巢良性上皮性肿瘤(良性肿瘤组),60例卵巢上皮性癌组织(卵巢上皮癌组)中VrEN的表达。结果PTEN在卵巢正常组、良性肿瘤组中的阳性表达率分别为100%(10/10)、80%(16/20),显著高于卵巢上皮癌组的53.3%(32/60)(X2值分别为7.778、4.444,P均〈0.05);而良性肿瘤组和正常卵巢组比较差异无统计学意义(P〉0.05)。PTEN蛋白表达与卵巢癌的临床分期、组织学分级、有无淋巴结转移和远处转移有关(X2值分别为4.339、6.465、3.896、10.452,P〈0.01或P〈0.05),而与年龄、病理类型、有无腹水无关(X2值分别为0.004、0.388、1.057,P均〉0.05)。结论PTEN表达缺失与卵巢上皮性癌的发生、发展关系密切,对临床诊断、治疗及预后评价具有重要意义。Objective To analyse the expression of phosphatase and tensin homolog deleted on chromosome 10 (PTEN) in ovarian epithelial cancer and to investigate the relationship between IYI'EN and clinical pathology and prognosis of ovarian epithelial cancer. Methods Expression of PTEN in 10 normal ovarian tissues, 20 benign tumors and 60 cases of ovarian epithelial cancers were detected by immunohistochemical method. Results The positive expression of PTEN in normal ovarian and benign tumor tissues were significantly higher than that in ovarian epithelial cancers( 100% (10/10) vs 80. 0% (16/20) vs 53.3% (32/60), X2 = 7. 778 and 4. 444 respectively, P 〈 0. 05 ). The expression of PTEN was correlated to clinical stage, histilogical grade, presence and metastasis of lymph node ( X2 = 4. 339 ;6. 465 ;3. 896 ; 10. 452 ;P 〈 0. 01 ) ,but there was no correlation to age,histological type and ascites(X2 =0. 004;0. 388;1. 057;P 〉0. 05). Conclusion The expression of PTEN is related to ovarian carcinogenesis and development and may has great value in clinical diagnosis and prognosis of ovarian carcinogenesis.
