摘要

摘要: 目的检测正常宫颈、宫颈CINⅡ-Ⅲ级及宫颈鳞癌组织中LRG1和CD105的表达, 探讨LRG1与宫颈鳞癌发病的相关性及其与微血管密度的关系.方法采用免疫组织化学SP法对40例宫颈鳞癌, 20例宫颈CINⅡⅢ级及20例对照组的正常宫颈组织进行LRG1、CD105表达水平的检测.结果 LRG1在正常宫颈、CINⅡⅢ级、宫颈鳞癌中的表达逐渐增高, 差异有统计学意义 (P<0.05) .LRG1的表达与临床分期和淋巴结转移有关 (P<0.05) , 与宫颈鳞癌患者年龄、肿瘤的大小、病理分级、浸润深度无关 (P>0.05) .随着宫颈病变的加深, CD105-MVD的表达逐渐增加, 差异有统计学意义 (P<0.05) .宫颈鳞癌组织中CD105-MVD的表达与临床分期、淋巴结转移及肿瘤大小有关, 差异有统计学意义 (P<0.05) , 与年龄、病理分级及浸润深度均无关 (P>0.05) .宫颈鳞癌组织中LRG1的阳性表达与CD105-MVD呈正相关 (r=0.944, P<0.05) .结论 LRG1及CD105在宫颈鳞癌中表达上调, 两者之间的表达呈正相关, LRG1及CD105的异常表达可能与宫颈鳞癌的发生、发展有关.

Abstract: Objective To investigate the expression of LRG1 (Leucine-rich alpha-2-glycoprotein 1) and CD105 (Endoglin) in normal cervical tissues, cervical intraepithelial neoplasia (CIN) Ⅱ-Ⅲ and cervical carcinoma. Furthermore, to explore the function of LRG1 in cervical carcinoma pathogenesis and the relationship between LRG1 and microvessel density.Me thods The expression levels of LRG1 and CD105 were detected by immunohistochemistry in 40 cervical carcinoma tissues, 20 CIN Ⅱ-Ⅲ tissues and 20 normal cervical tissues.Re s ults Compared to the normal cervix, the expression of LRG1 in CIN Ⅱ-Ⅲ and cervical squamous cell carcinoma was significantly increased (P<0.05) .LRG1 expression was correlated to clinical stage and lymph node metastasis (P <0.05) . But there was no correlation between LRG1 expression and age, the size of tumor, pathologic grades and depth of invasion (P > 0.05) .With the deepening of cervical lesions, CD105-MVD (X±s) increasedsignificantly (P<0.05) .The expression of CD105-MVD in cervical carcinomawas related to clinical stage, lymph node metastasis and the size of tumor. The difference was statistically significant (P<0.05) . There was no correlation between CD105-MVD and age, pathologic grades and depth of invasion (P > 0.05) .Positive correlation was found between the expression of LRG1 and CD105-MVD (r = 0.944, P <0.05) .Conclus ions The expression of LRG1 and CD105-MVD is up-regulated and shows a positive correlation, which suggests that the abnormal expression of LRG1 and CD105-MVD may involve in the occurrence and development of cervical squamous carcinoma.
