目的:探讨直肠小细胞癌Cox-2、nm23和MMP-3的表达及与临床病理特征的关系。方法应用免疫组织化学方法及组织芯片技术,观察63例直肠小细胞癌Cox-2、nm23和MMP-3的表达情况。结果 Cox-2、MMP-3阳性表达率与直肠小细胞癌的浸润深度、肠系膜淋巴结转移有关,随浸润深度加深,淋巴结转移率增加而升高(P <0?.05)。 Cox-2、MMP-3阳性表达率与直肠小细胞癌的TNM分期无关( P >0.05),nm23蛋白的阳性表达与肠系膜淋巴结转移,TNM分期有关,随淋巴结转移,TNM分期的增加而减低( P <0.05),与浸润深度无关( P >0.05)。 Cox-2、nm23和MMP-3的表达与患者年龄、性别无关( P >0.05)。结论直肠小细胞癌的nm23、Cox-2和MMP-3的表达与临床预后密切相关,联合检测可预测直肠小细胞癌的恶性程度及判断预后。

Objective To investigate the correlation between expression of Cox-2,nm23 and MMP-3 in small cell carcinoma of the rectum and clinicopathological characteristics .Methods The expression levels of Cox-2,nm23,MMP-3 in 63 cases of small cell carcinoma of rectum were detected by immunohistochemistry and tissue microarray technology .Results The positive expression rates of Cox-2,and MMP-3 were correlated to mesenteric lymph node metastasis and depth of tumor invasion,with the increase of infiltration depth of tumor ,lymph node metastasis rate was increased ( P <0.05).The positive expression rates of Cox-2 and MMP-3 were not correlated to TNM staging ( P >0.05).However positive expression of nm23 protein was related with mesenteric lymph node metastasis and TNM staging ( P <0.05),with lymph node metastasis and increase of TNM stage,which was decreased ( P <0.05),however,which was not related to infiltration depth of tumor ( P >0.05).The expression levels of Cox-2,nm23,MMP-3 were not correlated to patient's age and sex ( P >0.05).Conclusion The expression levels of Nm23,Cox-2 and MMP-3 in small cell carcinoma of rectum are closely related to clinical prognosis , and combined detection can predict the malignant degree of tumor and can evaluate patient ’ s prognosis .
