Abstract: 目的了解乳腺浸润性导管癌中雌激素调节蛋白(PS2)和谷胱甘肽S-转移酶π(GSTπ)的表达及其对预后和治疗的指导作用.方法用标记的链亲和素生物素(LSAB)免疫组化法对210例乳腺浸润性导管癌患者的石蜡标本进行PS2和GSTπ的检测.结果PS2的表达阳性率为49.5%,GSTπ的表达阳性率为48.1%.术后5年和10年生存率从高到低依次为PS2表达阳性/GSTπ表达阴性组、PS2表达阳性/GSTπ表达阳性组、PS2表达阴性/GSTπ表达阴性组和PS2表达阴性/GSTπ表达阳性组.结论PS2表达阳性/GSTπ表达阴性组患者的预后最好,PS2表达阳性/GSTπ表达阳性组和PS2表达阴性/GSTπ表达阳性组患者的预后次之,PS2表达阴性/GSTπ表达阳性组患者的预后最差.因此,在临床中应根据患者的情况合理应用内分泌治疗和化疗.
