结直肠癌中CD44v6、MMP-2、nm23-H1表达与临床病理的相关性研究
Correlation between expression of CD44v6, MMP-2 and nm23-H1 in colorectal carcinoma and its clinicalopathological characters

摘要: 目的 探讨结直肠癌中ＣＤ４４ｖ６、ＭＭＰ－２和ｎｍ２３－Ｈ１的表达与临床病理特征的关系。方法采用免疫组化 ＳＡＢＣ法结合计算机图像分析技术检测 ＣＤ４４ｖ６、ＭＭＰ－２、ｎｍ２３－Ｈ１蛋白在 ２４例结直肠癌患者癌及癌旁组织中的表达。结果 ２４例结直肠癌组织中 ＣＤ４４ｖ６、ＭＭＰ－２的阳性单位（ＰＵ值）高于癌旁和正常组织（Ｐ＜０．０５），而 ｎｍ２３－Ｈ１的 ＰＵ值则低于癌旁和正常组织（Ｐ＜０．０５）。它们的异常表达与患者的性别、年龄、肿瘤大小及部位无相关性，而与浸润深度、淋巴结转移、远处转移、Ｄｕｋｅ'ｓ分期密切相关（Ｐ＜０．０５）。结论 ＣＤ４４ｖ６、ＭＭＰ－２、ｎｍ２３－Ｈ１与结直肠癌的病理特征密切相关。它们的异常表达在肿瘤的侵袭转移中可能具有正、负协同作用，联合检测 ＣＤ４４ｖ６、ＭＭＰ－２、ｎｍ２３－Ｈ１蛋白可作为预测结直肠癌侵袭转移及客观评价患者预后的生物学指标。Abstract: Objective To study the expression of CD44v6, MMP-2 and nm23-H1 protein in colorectal carcinoma and its relation with clinicalopathological characters, and to investigate the correlation of CD44v6, MMP-2 and nm23-H1 expression in colorectal carcinoma. Methods Immunohistochemical method in combination with computer -imaging analysis technique was used to detect the expression level of CD44v6, MMP-2 and nm23-H1 in cancerous, paracancerous and normal tissues from 24 patient...
