Objective To Study the expression and clinical significance of VEGF-C and Podoplanin in esophageal carcinoma organizations. Methods Taking 50 examples esophageal carcinoma organizations of clinical surgery,and making use of immunohistochemistry measures to detect VEGF-C and podoplanin of esophageal carcinoma. Results Positive expression of VEGF-C can be found in cancer cell of esophageal carcinoma,positive particles lies mainly in ndochylema of tumour cell,further expression of VEGF-C obviously top the nonage in advanced esophageal carcinoma, expression of VEGF-C have nothing to do with gender and age. Podoplanin is expressed only in lymph-vessel bast cell, the advanced time cancer of the esophagus progressing organizes obvious tiny lymph-vessel density及Podoplanin的表达进行研究,为防治食管癌淋巴道转移提供科学的理论基础,从而使其具有很高的实用价值。
1 材料与方法
1.1实验材料与试剂
取齐齐哈尔市第一医院2006~2008年经手术切除并证实为食管鳞癌的标本50例,其中早期22例,进展期28例;有淋巴结转移31例,无淋巴结转移19例;男性41例,女性9例;年龄最小35岁,最大82岁。
兔抗人VEGF-C多克隆抗体,兔抗人Podoplanin单克隆抗体,PV9000二步法免疫组化试剂盒均购自武汉博士得生物工程有限公司。
1.2实验方法
将食管癌标本在癌周边区取材,经4%多聚甲醛固定,石蜡包埋,石蜡切片机连续4μm厚度切片,免疫组化染色,DAB显色,苏木素复染,光学显微镜观察。
1.3统计学处理
采用SPSS13.0统计软件进行数据分析与整理。
2结果
2.1VEGF-C的表达
在早期食管癌组织中VEGF-C表达于癌细胞胞浆,呈散在的棕黄色颗粒状,阳性率为22.73% and KDR:157-166.
