1、[经典]MIF和MMP-2在宫颈癌中的表达及临床意义MTF和MMP-2在宫颈癌中的表达及临床意义【摘要】目的探讨巨噬细胞移动抑制因子(MTF)及基质金属蛋白酶-2(W-2)在宫颈癌的表达及临床意义。方法采用免疫组化SP法检测68例宫颈癌组织、24例宫颈上皮内瘤病变(CIN)组织和21例正常宫颈组织(对照组)中MTF及MMP-2的表达,并对宫颈癌组织MTF与MMP-2表达进行相关性分析。结果宫颈癌组MIF和W-2阳性表达率显著高于CTN组和对照组;宫颈癌组不同临床分期、组织分化、有无淋巴结转移之间比较,MTF和MMP-2的阳性表达率均有显
2、著性差异(P〈0.05),且二者表达强度呈显著正相关(r=0.82,P<0.05)o结论MTF和MMP-2过表达可能与宫颈癌的发生、发展有关,二者联合检测可作为评估宫颈癌恶性程度、判断预后及指导治疗的重要参考指标。【关键词】宫颈癌;巨噬细胞移动抑制因子;基质金属蛋白酶-2;免疫组织化学ExpressionandclinicalsignificanceofMTFandMMP-2incervicalcancerTANChen,LUOZhao-yang.CancerInstitute,UniversityofSouthChina,Hengya
