摘要
目的 研究细胞外基质金属蛋白酶诱导因子(EMMPRIN)和血管内皮生成因子-C(VEGF-C)蛋白表达与乳腺癌浸润和转移之间的关系.方法 免疫组化法检测乳腺增生组21例、导管内癌组10例、浸润性导管癌组68例病灶内EMMPRIN和VEGF-C蛋白的表达情况.结果 EMMPRIN蛋白在增生组、导管内癌组、浸润性导管癌组表达阳性率分别为4.76%(1/21)、40.00%(4/10)73.53%(50/68),3组之间的阳性率差异均有统计学意义(P〈0.01).VEGF-C蛋白在增生组、导管内癌组、浸润性导管癌组表达阳性率分别为14.29%(3/21)、60.00(6/10)、77.94%(53/68),导管内癌组和浸润性导管癌组阳性率明显高于增生组(P〈0.01).乳腺癌组织中EMMPRIN和VEGF-C的表达呈正相关(rs=0.390,P〈0.01),而且EMMPRIN和VEGF-C的表达与腋窝淋巴结转移及淋巴结转移数目有关(P〈0.01).结论 EMMPRIN和VEGF-C的过度表达是促进乳腺癌浸润和转移的重要因素,二者在乳腺癌的浸润和转移过程中可能起着协同作用.
Objective To study the correlation of EMMPRIN and VEGF-C expression with invasion and metastasis of breast carcinoma. Method The expression of EMMPRIN and VEGF-C was detected by immunohistochemical technique in 21 cases hyperplasia of mammary glands, 10 cases of in-tubule carcinoma and 68 cases invasive carcinoma. Results The positive rate of EMMPRIN expression in hyperplasia of mammary glands, in-tubule carcinoma and invasive carcinoma were 4. 76% (1/21), 40. 00% (4/10)73.53% (50/68), respectively;Significant difference was found among three groups ( P 〈 0.01 ). The positive rate of VEGF-C expression in hyperplasia, in-tubule carcinoma and invasive carcinoma were14. 29% (3/21) ,60. 00 (6/10) ,77.94% (53/68), respectively. The positive rates of VEGF-C expression in situ and invasive ductal carcinoma were remarkably higher than that of hyperplasia of mammary glands ( P 〈0. 01 ). The expression of EMMPRIN significantly correlated with the expression of VEGF-C in breast tubule carcinoma ( rs =0. 390, P 〈0. 01 ), Lymph nod metastasis and the number axillary Lymph nod metastasis were related to EMMPRIN and VEGF-C ( P 〈 0. 01 ). Conclusion The over-expression of EMMPRIN and VEGF-C were important elements to promote the invasiveness and metastasis of breast carcinoma. Synergistic effect between EMMPRIN and VEGF-C may take place in lymph node metastasis of breast carcinoma.
