摘要
目的:探讨食管癌组织MMP-2表达与肿瘤细胞增殖以及肿瘤侵袭、转移的关系.方法:用免疫组织化学S-P法,检测75例食管癌、30例对照组(食管切缘正常组织)MMP-2、Ki67的表达,分析MMP-2表达与临床病理因素的关系.结果:食管癌MMP-2和Ki67表达率分别为82.7%和78.7%(均高于正常食管组织,(P<0.005),两者均表达51例,符合率为74.7%,两者差异无显著性(P>0.05);MMP-2表达与癌细胞的血管侵袭、侵袭深度、食管旁淋巴结转移有一定的关系(P<0.05~P<0.005),而与患者的年龄、性别和肿瘤大小均无明显关系(P>0.05).结论:食管癌的MMP-2表达与肿瘤细胞的增殖以及肿瘤侵袭、转移相关,在食管癌的发展过程中起重要作用.MMP-2可作为评价食管癌恶性潜能的生物学标志物.
Objective:To investigate the expression of matrix metalloproteinase 2(MMP-2) and its oorrelation with expression of Ki67 and proliferative, invasiveness and metastasis in human esophageal carcinoma(EC). Methods.The expressions of MMP-2 and Ki67 were detected in 75 cases of EC and 30 cases of oontrols by immunohistochemical stain(S-P method) and their relationship with the dinloopathologic factors was analyzed. Results:The positive rates of MMP-2 and Ki67 were 82.7% and 78.7% respectively in EC group.The positive rates of MMP-2 and Ki67 in EC group were significantly higher than those in oontrol group(P 〈 0.05). The expressions of MMP-2 and Ki67 were detected in 51 cases, and the accord rate of was 74.7% (P 〉0.05). The expression of MMP- 2 in EC group was oorrelated with vessel invasion, depth of invasion, and metastasis to the paraesophageal lymph nodes except age, sex and tumor size( P 〈 0.05 - P 〈 0. 005 ). Conclusions-The expression of MMP-2 in EC is closely related with proliferative, invasiveness and metastasis of toumor cell. Expression of MMP-2 might play an important role in the development of EC,and MMP- 2 become a biological marker for evaluating the malignant potential of EC.
