乳腺癌组织中 VEGF-D、MMP-2及 MMP-9的表达及其临床意义

目的：探讨乳腺癌组织中基质金属蛋白酶-2（MMP-2）、基质金属蛋白酶-9（MMP-9）和血管内皮生长因子D（ VEGF-D）表达的临床意义。方法采用免疫组化法，对60例乳腺癌组织及60例正常组织中 MMP-2、MMP-9及VEGF-D表达情况进行检测。结果60例乳腺癌组织中，MMP-2、MMP-9阳性表达率分别为61．67％、56．67％，VEGF-D阳性表达率为61．67％。 MMP-2、MMP-9及VEGF-D阳性表达率Ⅲ～Ⅳ期者显著高于Ⅰ～Ⅱ期者；低分化者显著高于高、中分化者；有淋巴结转移者显著高于无淋巴结转移者；且MMP-2与VEGF-D表达，MMP-9与VEGF-D表达均呈正相关性。结论低分化、Ⅲ～Ⅳ期乳腺癌患者高表达MMP-2、MMP-9与VEGF-D，MMPs与VEGF-D表达呈正相关性，可通过阻断VEGF-D及MMPs活性控制、治疗乳腺癌。

The Expressions and Clinical Significance of Matrix Metalloproteinases 2(MMP-2),Ma-trix Metalloproteinases 9 (MMP-9) and Vascular Endothelial Growth Factor-D (VEGF-D) in Breast Cancer

Objective To explore the expressions of matrix metalloproteinases 2 ( MMP-2 ) ,matrix metalloproteinases 9 (MMP-9) and vascular endothelial growth factor-D(VEGF-D)and their significance in breast cancer tissues.Methods The ex-pressions of MMP-2,MMP-9 and VEGF-D in 60 cases of breast cancer tissues and 60 cases of normal esophageal tissues were de-tected by immunohistochemistry.Results The expression rates of MMP-2,MMP-9 and VEGF-D in breast cancer tissues were 61.67%,56.67%and 61.67%.The expression rates of MMP-2,MMP-9 and VEGF-D in grade Ⅲ-Ⅳ were significantly higher than that of gradeⅠ-Ⅱ.The expression rates of MMP-2,MMP-9 and VEGF-D in patients with poor differentiation were signifi-cantly higher than that with well-mediate differentiation.The expression rates of MMP-2,MMP-9 and VEGF-D in patients with lymph node metastasis were significantly higher than that without lymph node metastasis.MMP-2 and VEGF-D expression were positively correlated.MMP-9 and VEGF-D expression were also positively correlated.Conclusion The expression rates of MMP-2,MMP-9 and VEGF-D are closely related to poor differentiation,gradeⅢ-Ⅳin the breast cancer.Their expressions appear to be well-characterized indicators of tumor prognosis and metastasis.
