目的 了解乳腺浸潤性導(dǎo)管癌中雌激素調(diào)節(jié)蛋白(PS2)和谷胱甘肽S轉(zhuǎn)移酶π(GSTπ)的表達(dá)及其對預(yù)后和治療的指導(dǎo)作用。
方法 用標(biāo)記的鏈親和素生物素(LSAB)免疫組化法對210例乳腺浸潤性導(dǎo)管癌患者的石蠟標(biāo)本進(jìn)行PS2和GSTπ的檢測。
結(jié)果 PS2的表達(dá)陽性率為49.5%,GSTπ的表達(dá)陽性率為48.1%。術(shù)后5年和10年生存率從高到低依次為PS2表達(dá)陽性/GSTπ表達(dá)陰性組、PS2表達(dá)陽性/GSTπ表達(dá)陽性組、PS2表達(dá)陰性/GSTπ表達(dá)陰性組和PS2表達(dá)陰性/GSTπ表達(dá)陽性組。
結(jié)論 PS2表達(dá)陽性/GSTπ表達(dá)陰性組患者的預(yù)后最好,PS2表達(dá)陽性/GSTπ表達(dá)陽性組和PS2表達(dá)陰性/GSTπ表達(dá)陽性組患者的預(yù)后次之,PS2表達(dá)陰性/GSTπ表達(dá)陽性組患者的預(yù)后最差。因此,在臨床中應(yīng)根據(jù)患者的情況合理應(yīng)用內(nèi)分泌治療和化療。
