[Abstract)Objective: Decoy receptor 3(DcR3) ,a new member of tumor necrosis factor receptor(TNFR) super family,is not only upregulated in cancer cells derived from various cell lineages , but also correlates with the overall survival of certain cancer patients, We studied a possible association between DcR3 expression and prognosis in pa-tients with epithelial ovarian carcinoma. Methods; Protein expression of DcR3 was compared in 38 normal human o-varian tissues ,29 benign ovarian tissues and 86 epithelial ovarian cancer(EOC) by immunohistochemistry( IHC). Re sults:Expression of DeR3 in EOC was significantly higher than that in nomal ovarian tissues( P <0. 01) and benign ovarian tissues(P <0. 05) ,respectively. It was also found that DcR3 expression in well differentiated EOC was signifi-cantly low than that in poorly differentiated specimens( P <0. 05). Patients in stages I and II showed significantly low-er DcR3 expression compared with that in stages III and IV( P <0. 05) . DcR3 expression in lymph node metastasis -negative patients was significantly decreased in comparison with that in lymph node metastasis positive patients( P < 0. 05). Conclusion : DcR3 protein expression is significantly over expressed in malignant tumors compared to normal ovaries and benign tumors, While it is relatively unchanged in benign tumors compared to normal ovary. The DcR3 a eaa eai aoeeoed e asa EOC patients.

【摘要】目的:诱骗受体3(decoyreceptor3,DeR3)是肿瘤坏死因子受体(TNFR)家族的成员,影响着多种肿瘤的发生发展,本实验研究探讨其与卵巢癌发生发展及预后的关系。方法:应用免疫组织化学SP法检测38 例正常卵巢组织、29例卵巢良性肿瘤及86例卵巢上皮性癌组织中DcR3蛋白的表达情况。结果:DcR3蛋白在卵巢瘤组织中的表达明显高于卵巢良性肿瘤及正常组织中的表达;DcR3蛋白在卵巢上皮性癌I-Ⅱ期表达较Ⅲ-IV期明显减弱;在高中分化组织中的表达明显低于低分化组织;在淋巴结转移组的表达高于无淋巴结转移组,各组间差异均具有统计学意义(P<0.05)。DcR3蛋白表达越强,患者生存时间越短(P<0.05)。结论:DcR3表达水平与卵巢上皮性癌临床分期、组织分化、肿瘤浸润、转移及预后有关,有可能成为一种卵巢癌肿瘤特异性指标。

卵巢上皮性癌是女性生殖系统肿瘤中死亡率最高的肿瘤,且居于女性癌症相关死因的第五位"]。在已确诊患者中,约70%卵巢瘤患者已经扩散转移为Ⅲ-IV期癌。尽管现在外科手术和靶向药物的应用已经进展成熟,但是邮巢需患

者的5年生存率也仅有30%1-2)。因此进一步探导卵巢癌致病因素及发生、发展、预后相关因索成为现在研究的热点。诱骗受体3(decoyreceptor3,DcR3;文称为TR6或M68)是 1998年Pitti等(3)发现的肿瘤坏死因子受体(tumornecrosis factorreceptor,TNFR),是一种特殊的细胞调亡抑制剂,能和肿瘤坏死因子超家族成员Fas配体、LICHT以及TLIA相结合,对它们介导的细胞凋亡起负调控的作用,它在肿瘤免疫、白身免疫、移植免疫和抗病毒免疫中发挥着重要的作用4]。本实验应用免疫组化法检测卵巢上皮性肿瘤中DcR3蛋白的表达水平,并分析其与上皮性卵巢癌的临床病理因素和预后的关系,探索其对于卵巢癌生物学行为及预后的价值。
