【摘要】目的研究血尿激酶型纖溶酶原激活劑（uPA）mRNA水平表達(dá)與乳腺癌及淋巴結(jié)轉(zhuǎn)移的關(guān)系及其臨床意義。
方法應(yīng)用熒光定量RT-PCR方法，檢測(cè) 60例乳腺良、惡性腫瘤患者血中uPA mRNA水平的表達(dá)，分析其與乳腺癌及其淋巴結(jié)轉(zhuǎn)移的關(guān)系。
結(jié)果uPA mRNA表達(dá)在18例良性腫瘤患者中16例為陰性，2例為低表達(dá)。在42例乳腺癌患者中，無淋巴結(jié)轉(zhuǎn)移的20例中18例為陽性，其中1例為高表達(dá)， 5例為中度表達(dá)，12例為低表達(dá)，另2例為陰性； 有淋巴結(jié)轉(zhuǎn)移的22例均為陽性，其中16例為高表達(dá)，5例為中度表達(dá)，1例為低表達(dá)。乳腺良、惡性腫瘤患者血中uPA mRNA表達(dá)差異有顯著性意義（P＜0.05）； 乳腺癌患者中無淋巴結(jié)轉(zhuǎn)移者uPA mRNA的表達(dá)強(qiáng)度明顯低于有淋巴結(jié)轉(zhuǎn)移者（P＜0.05）。
結(jié)論血中uPA mRNA在乳腺癌中的表達(dá)明顯高于良性腫瘤，其表達(dá)強(qiáng)度與乳腺癌淋巴結(jié)轉(zhuǎn)移明顯相關(guān)，可為臨床分期及后續(xù)治療提供依據(jù)。
