摘要: 目的:研究促血管生成素-2(Ang-2)在上皮性卵巢癌血管生成及肿瘤生长中的作用。方法:应用免疫组化法检测46例上皮性卵巢癌和25例正常卵巢组织石蜡标本Ang-2和CD34表达,并以CD34标记的微血管计算组织的微血管密度(MVD)。结果:上皮性卵巢癌组织中Ang-2表达率高于正常卵巢组织(P<0.05),Ⅲ期和Ⅳ期合并组Ang-2表达率高于Ⅰ期和Ⅱ期合并组(P<0.05);上皮性卵巢癌中Ang-2表达与其病理类型及组织学分级无关,而与MVD呈正相关(r=0.733,P<0.01)。结论:Ang-2与上皮性卵巢癌的血管生成及其发展密切相关,可能通过促进上皮性卵巢癌中的血管生成而促进其发展。

Abstract: Objective To examine the expression of angiopoietin-2(Ang-2) in normal ovary and epithelia ovarin carcinoma,and discuss the relationship between Ang-2 and clinical pathological features of epithelia ovarian carcinoma.Methods The expressions of Ang-2 and CD34 in 46 paraffin specimens of epithelia ovarian carcinoma and 25 paraffin specimens of normal ovary were detected by immunohistochemistry SABC technique,and the microvessel density(MVD)of tissues signed by CD34 was counted. Results The expression of Ang-2 in epithelia ovarian carcinoma was higher than that in normal ovary tissue (P<0.05). The expression of Ang-2 in the stageⅠand Ⅱepithelia ovarian carcinoma was lower than that in stage Ⅲ and Ⅳ(P<0.05);The expression of Ang-2 in epithelia ovarian carcinoma was not correlated to types and degrees of histology. There was a remarkable positive correlation between the expression of Ang-2 and MVD in epithelia ovarian carcinoma(r=0.733,P<0.01).Conclusion The expression of Ang-2 might be related to the development of epithelia ovarian carcinoma,and may promote the development of epithelia ovarian carcinoma by promoting angiogenesis in tumor.
