摘要: 目的 探讨胰腺癌中基质金属蛋白酶 (MMP) -9与Ki67表达的相关性及其临床意义。方法 采用S-P免疫组化染色技术, 检测100例胰腺癌中MMP-9及Ki67的表达情况, 分析其表达水平与年龄、 肿瘤大小、 淋巴结转移、 TNM分期、 分化程度及术后生存时间的相关性。结果 100例胰腺癌中, MMP-9高表达46例 (46%), Ki67高表达53例(53%), 且淋巴结有转移、 TNM分期级别高、 病理分化程度低患者的MMP-9和Ki67的表达高于无淋巴结转移、TNM分期级别低和病理分化程度高的患者 (P<0.05), 不同年龄、 肿瘤直径间MMP-9和Ki67的表达差异无统计学意义。MMP-9与Ki67表达呈正相关 (rs=0.405, P<0.05)。生存结局与年龄、 淋巴结转移、 病理分化程度、 MMP-9表达相关, 与肿瘤大小、 局部浸润及Ki67表达无关。结论 MMP-9与Ki67表达在胰腺癌的侵袭中起协同作用。MMP-9表达对于判断预后和指导治疗具有一定的临床价值。

Abstract: Abstract Objective:This study was designed to investigate the expression of MMP-9 and Ki67 in pancreatic cancer (PC).Methods:The expression of MMP-9 and Ki67 were detected by S-P immunohistochemical methods in 100 PC patients.Results:The survival rate in patients was correlated MMP-9 and Ki67 expressions(P<0.005).MMP-9 expressions were correlated with TNM staging and lymph node metastasis in PC (P<0.025, P<0.025).Ki67 expressions were correlated with TNM staging, lymph node metastasis, the degree of differentiation in PC (P<0.025, P<0.005, P<0.005). Conclusion:Combined detection of expression of MMP-9 and Ki67 in PC may have practical value in prognosis of the PC patients.
