1、南昌大学学报(医学版)2014年第54卷第5期JournalofNanchangUniversity(MedicalSciences)2014,Vo1.54No.533乳腺癌外周血微转移与微血管密度相关性研究及临床意义卫文俊,王玉蓉,陶霖玉,齐柯,陈天文,张好云,冯铎(广东医学院附属南山医院甲乳外科,广东深圳518052)摘要:目的研究乳腺癌外周血微转移与相应肿瘤组织微血管生成的关系,并探讨其临床意义。方法采用逆转录聚合酶链反应(RT-PCR)方法,对5O例乳腺癌(乳癌组)及3O例乳腺良性肿瘤患者(对照组)外
2、周血中乳腺上皮黏蛋白(smallbreastepithelialmucin,SBEM)表达情况进行检测;采用免疫组织化学法,用CD105标记肿瘤新生血管,计数乳腺癌和乳腺良性肿瘤组织微血管密度(MVD);分析其相关性及与临床病理特征之间的关系。结果乳癌组SBEM的阳性表达率为36(18/50),高于对照组的0.0(0/30)(P<0.05);乳癌组MVD值为24.56±4.12,高于对照组的8.61士2.87(P<0.05);乳癌组SBEM表达与MVD计数呈正相关(r=0.712,P<0.05),与TNM分期
3、、淋巴结转移密切相关(P<0.05);乳癌组MVD计数与肿瘤大小、淋巴结转移、TNM分期有关(P<0.05)。结论乳腺癌外周血微转移与相应癌组织微血管密度密切相关,MVD较高者更易发生外周血微转移,并与肿瘤的发生、发展和转移有关。关键词:乳腺癌;乳腺上皮黏蛋白;微转移;微血管密度中图分类号:R737.9文献标志码:A文章编号:2095—4727(2014)05—0033—04CorrelationbetweenPeripheralBloodMicrometastasisandMicrovesselDensit
