原发性乳腺癌恶性钙化乳腺钼靶摄片征象特征与TWIST蛋白、VEGF及E-cadherin的表达相关性研究

背景与目的:现阶段国内女性群体中原发性乳腺癌发生率呈逐渐提升趋势,对女性身心健康造成极大影响。因此对原发性乳腺癌恶性钙化钼靶摄片征象特征及与血管内皮生长因子(vascular endothelial growth factor,VEGF)以及上皮钙黏蛋白(E-cadherin,E-Cad)表达相关性进行系统分析,以便于为临床诊治提供针对性指导。方法:运用回顾性分析法对常州市第二人民医院2015年3月—2019年4月收治的经手术后病理学检查证实的243例原发性乳腺癌患者的资料进行研究,均于术前接受乳腺钼靶摄片检查,并在术后接受了病理、免疫组织化学检测,以手术后病理学检查结果为金标准,分析本组诊断结果。结果:本组243例患者中,恶性钙化118例,无恶性钙化125例;通过分析,Twist蛋白和乳腺癌恶性钙化的发生、形态以及数量存在显著相关性,且乳腺癌组织内Twist蛋白阳性表现与VEGF阳性表达呈正相关(P<0.05),Twist蛋白阳性表现与E-Cad阳性表达呈负相关(P<0.05)。结论:Twist蛋白、VEGF、E-Cad表达可为乳腺癌恶性钙化钼钯摄片诊断提供生物学基础,有着重要临床意义。

Expression levels of CXCR4 and VEGF correlate with blood-borne metastatic progression and outcome in patients with osteosarcoma

Objective:We determine whether chemokine receptor CXCR4 and vascular endothelial growth factor(VEGF) expression related to the metastasis and survival outcome of patients with osteosarcoma.Methods:Tissue microarray(TMA) was used to detect the expression of CXCR4 and VEGF in 56 osteosarcoma patient samples.Two-year follow-up was performed to observe the metastatic behavior and overall survival of osteosarcoma patients.Results:There was a significant correlation between the expression levels of CXCR4 and VEGF in 56 osteosarcoma patient samples(P = 0.002).Univariate analysis revealed the expression of CXCR4 and VEGF was not associated with age, gender and the level of ALP but associated with clinical stage.Conclusion:These data raises the possibility that VEGF could regulate the levels of CXCR4 to promote the migration of tumor cells to target organs.CXCR4 and VEGF expression are highly correlated with metastatic progression in patients with osteosarcoma and their immunohistochemical expression have predictive value for the metastatic development.
