應(yīng)用免疫組化法測(cè)定50例乳腺癌和12例乳腺良性病變組織中c-met蛋白及轉(zhuǎn)化生長(zhǎng)因子α(TGF-α)的表達(dá)。結(jié)果:乳腺癌組織中c-met蛋白及TGF-α表達(dá)陽(yáng)性率分別為26.0%和42.0%,乳腺良性病變組織中兩者表達(dá)陽(yáng)性率分別為8.3%和25.0%;組織學(xué)分級(jí)為Ⅰ級(jí),雌激素受體(ER)、孕激素受體(PR)及癌胚抗原(CEA)為陰性的病例中,c-met蛋白及TGF-α表達(dá)陽(yáng)性率明顯低于組織學(xué)分級(jí)Ⅲ級(jí),ER、PR及CEA為陽(yáng)性者(c-met及PR P<0.01;TGFα、PR和CEA P<0.05;余P>0.05)。本實(shí)驗(yàn)結(jié)果提示:c-met蛋白及TGF-α表達(dá)可能與乳腺癌發(fā)生發(fā)展及體機(jī)內(nèi)分泌狀態(tài)有較密切關(guān)系。
