Methods： SBEM and hMAM expressions in PB samples of 109 primary breast cancer patients were detected by flow cytometry （FCM） and RT- PCR. Relationship between the biomarkers＇ expression and prognostic parameters were analyzed. Results： SBEM and hMAM expressions in PB of breast cancer patients were much higher than those of healthy donors and other cancer patients. SBEM and hMAM expressed in 53.2% （50/94） and 39.4% （37/94） cases at stages I-III and expressed in 73.3% （11/15） and 46.7% （7/15） cases at stage IV respectively. SBEM and hMAM mRNA were only detected in PB samples of breast cancer patients, while no expression of them was found in that of healthy donors and other cancer patients. Conclusion： hMAM mRNA detection maybe helpful to predict hematogenous micrometastasis in ER-positive, well-differentiated breast cancers and SBEM mRNA detection maybe helpful to predict hematogenous micrometastasis in ER-negative, poody-differentiated breast cancers.展开更多
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50例乳腺癌(乳癌组)及30例乳腺良性肿瘤患者(对照组)外周血中乳腺上皮黏蛋白(small breast epithelial mucin,...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50例乳腺癌(乳癌组)及30例乳腺良性肿瘤患者(对照组)外周血中乳腺上皮黏蛋白(small breast epithelial mucin,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±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、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。展开更多
目的:研究血清骨桥蛋白(osteopontin,OPN)、乳腺小黏蛋白(small breast epithelial mucin,SBEM)及环氧化酶-2(Cyclooxygenase-2,COX-2)对乳腺癌患者的诊断价值。方法:分析106例乳腺癌患者的临床资料,并列为观察组,选取122例同期体检的...目的:研究血清骨桥蛋白(osteopontin,OPN)、乳腺小黏蛋白(small breast epithelial mucin,SBEM)及环氧化酶-2(Cyclooxygenase-2,COX-2)对乳腺癌患者的诊断价值。方法:分析106例乳腺癌患者的临床资料,并列为观察组,选取122例同期体检的健康妇女作为对照组。采用酶联免疫吸附试验法分别检测两组血清中OPN、SBEM、COX-2的定量值。结果:观察组患者血清OPN、SBEM及COX-2水平明显高于对照组,差异具有统计学意义(P<0.05);随着TMN分期的升高乳腺癌患者血清OPN、SBEM及COX-2水平呈现明显升高的趋势,差异均具有统计学意义(P<0.05);淋巴结转移的乳腺癌患者血清OPN、SBEM及COX-2水平高于无淋巴结转移的乳腺癌患者,差异均具有统计学意义(P<0.05);当OPN取71.00 ng/m L,对乳腺癌诊断敏感性为92.45%,特异性为84.43%,诊断价值明显优于SBEM、COX-2。结论:OPN、SBEM及COX-2在乳腺癌患者外周血中表达上调,均与乳腺癌发生、发展及恶性程度密切相关,其中OPN的诊断价值最高,可作为乳腺癌诊断新的靶点。展开更多
目的探讨不同人群外周血中乳腺小黏蛋白(small breast epithelial mucin,SBEM)水平以及乳腺癌患者外周血中SBEM水平与病理因素的关系和临床意义。方法收集经病理证实的68例乳腺癌及20例乳腺纤维腺瘤和20例健康志愿者。采用酶联免疫吸附...目的探讨不同人群外周血中乳腺小黏蛋白(small breast epithelial mucin,SBEM)水平以及乳腺癌患者外周血中SBEM水平与病理因素的关系和临床意义。方法收集经病理证实的68例乳腺癌及20例乳腺纤维腺瘤和20例健康志愿者。采用酶联免疫吸附测定法(ELISA)检测3组不同人群血清SBEM水平。分析乳腺癌患者外周血中SBEM水平与病理因素的关系。3组均抽取空腹静脉血3ml。采集血样前乳腺癌患者及纤维腺瘤组患者均未接受放疗、化疗或生物治疗等干预措施及有创检查。统计分析,符合正态分布的,两组间比较采用独立样本t检验,多组间比较行方差分析,LSD法进行两两比较。不符合正态分布的多组比较采用Kruskal-Wallis H检验。结果 3组间血清SBEM水平差异存在显著的统计学意义(P<0.050)。乳腺癌组血清SBEM水平均高于纤维腺瘤组和健康志愿者组(P均<0.001)。纤维腺瘤组与健康志愿者组相比,差异无统计学意义(P>0.050)。乳腺癌患者的血清SBEM水平与淋巴结转移状况和TNM分期有关(P均<0.001),与患者的年龄、月经状况、病理类型、组织学分级、肿瘤大小、ER、PR、HER-2、P53、Ki-67、基因分型无关(P均>0.050)。乳腺癌SBEM血清水平随淋巴结分期增加而升高,不同淋巴结分期间的SBEM水平差异有显著的统计学意义(P<0.001)。结论 SBEM特异性表达于乳腺癌外周血。乳腺癌患者外周血SBEM水平在一定程度上能够反映临床分期和腋窝淋巴结情况,有望成为检测乳腺癌外周血微转移的标志物和判断乳腺癌病情发展和预后的指标。展开更多
