基质金属蛋白酶-2、半胱氨酸富集蛋白61及CD25在食管鳞癌中表达及其意义

目的 检测基质金属蛋白酶-2(MMP-2)、半胱氨酸富集蛋白61（Cyr61）及CD25在食管鳞癌中的表达并探讨其临床意义。方法 采用免疫组织化学法分别检测68例食管鳞癌患者肿瘤组织（食管癌组）、癌旁组织（癌旁组）和68例反流性食管炎患者病变组织（对照组）中的MMP-2、Cyr61及CD25，对检测结果进行统计分析。结果 食管癌组中MMP-2、Cyr61和CD25的阳性表达率分别为82.35％( 56/68)、73.53％ (50/68)和89.71％(61/68)，与癌旁组、对照组比较差异均有统计学意义(P＜0.05)；癌旁组与对照组比较差异无统计学意义(P＞0.05)；食管癌组织中MMP-2、Cyr61和CD25的阳性表达率在不同T分期、N分期和M分期中差异均有统计学意义(P＜0.05)，在不同的分化程度中差异则无统计学意义(P＞0.05)。结论 MMP-2、Cyr61及CD25在食管鳞癌中均有高表达，对其进行检测对了解食管鳞癌的发生、发展以及预后判断有一定指导意义。

Expression of matrix metalloproteinase-2,cysteine rich protein61 and CD25 In esophageal carcinoma and their significance

Objective To determine the expression of matrix metalloproteinase-2 (MMP-2),cysteine rich protein 61 (Cyr61) and CD25 in esophageal carcinoma and investigate their clinical significance.Method The expression of MMP-2, Cyr61 and CD25 in 68 cases of esophageal tumor tissues (esophageal carcinoma group ) and part-cancer( para-cancer group ) and 68 cases of reflux esophagitis (control group ) was detected by immunohistochemical method and the results were statistically analysed. Results The positive expression rates of MMP-2,Cyr61 and CD25 were 82.35％(56/68), 73.53％(50/68) and 89.71％(61/68)respectively in esophageal carcinoma group,there were significant differences compared with those in paracancer group and control group(P ＜ 0.05) ; while there was no significantdifference between para-cancer group and control group (P ＞ 0.05 ). The positive expression rates of MMP-2, Cyr61 and CD25 in esophageal carcinoma group in different T stage, N stage and M stage all had statisticall differences (P ＜ 0.05),while there was no significant difference in different degree of differentiation (P ＞ 0.05 ). Conclusion MMP-2,Cyr61 and CD25 is highly expressed in esophageal carcinoma,there is some significance for understanding the occurrence, development and prognosis of esophageal carcinoma.
