    摘要:

    目的:探讨基质金属蛋白酶2(MMP-2)与基质金属蛋白酶9(MMP-9)在肝内胆管细胞癌(ICC)组织中的表达及其与ICC患者临床病理特征及预后的关系。 方法:收集2011年1月—2014年12月收治的50例ICC患者的癌组织与癌旁组织手术标本,采用免疫组织化学方法及RT-PCR方法检测MMP-2和MMP-9在以上组织中的表达,分析MMP-2和MMP-9表达与ICC患者临床病理参数以及术后生存率的关系。 结果:免疫组织化学结果显示,ICC组织中MMP-2和MMP-9蛋白阳性表达率分别为34.0%和32.0%,而两者在癌旁组织中无阳性表达;RT-PCR结果显示,ICC组织中MMP-2和MMP-9的相对表达均明显高于癌旁组织(均P<0.05)。MMP-2和MMP-9表达与ICC患者是否存在淋巴结转移和肿瘤分化程度有关(均P<0.05),而与患者性别、年龄和肿瘤分期无关(均P>0.05);MMP-2和MMP-9阳性患者生存率明显低于各自阴性者,而两者均阳性患者的生存率最低(均P<0.05)。 结论:ICC组织中MMP-2和MMP-9表达明显上调,且两者的表达与ICC患者恶性临床病理特征及不良预后密切相关。

    Abstract:

    Objective: To investigate the expression of matrix metalloproteinase 2 (MMP-2) and 9 (MMP-9) in intrahepatic cholangiocarcinoma (ICC) and their relations with the clinicopathologic features and prognosis of ICC patients. Methods: The surgical specimens including tumor and tumor-adjacent tissue from 50 ICC patients treated between January 2011 and December 2014 were collected. The MMP-2 and MMP-9 expressions in these tissues were detected by immunohistochemical staining and RT-PCR method, and the relations of MMP-2 and MMP-9 expressions with clinicopathologic variables and postoperative survival of ICC patients were analyzed. Results: Results of immunohistochemical staining showed that the positive expression rate of MMP-2 and MMP-9 in ICC tissue was 34.0% and 32.0% respectively, but neither was positive in tumor-adjacent tissue; results of RT-PCR showed that both relative expression levels of MMP-2 and MMP-9 in ICC tissue were significantly higher than those in tumor-adjacent tissue (both P<0.05). Both MMP-2 and MMP-9 expressions were significantly associated with the presence or absence of lymph node metastasis and degree of tumor differentiation of ICC patients (all P<0.05), but were irrelevant to the gender, age and tumor stage of ICC patients (all P>0.05); the survival rate in patients with positive MMP-2 or MMP-9 expression was significantly lower than that in patients with negative MMP-2 or MMP-9 expression, and those with both MMP-2 and MMP-9 positive expressions had lowest survival rate (all P<0.05). Conclusion: MMP-2 and MMP-9 expressions are increased in ICC tissue, and both expressions are closely related to the malignant clinicopathologic profiles and poor prognosis of ICC patients.
