目的:探讨三种耐药蛋白GST - π,P - gp,Topo -Ⅱ在乳腺癌组织中的表达,比较分析三种耐药相关
基因蛋白在不同临床特点的乳腺癌和不同分子分型乳腺癌组织中的表达差别,为临床治疗提供依据。方法:采
用免疫组织化学HRP 法检测60 例Luminal A 型;60 例Her - 2( + )(其中含有Her - 2 阳性的Luminal B 型);46
例三阴性乳腺癌组织中GST - π,P - gp 和Topo -Ⅱ的表达,并结合病理特点进行分析。结果:GST - π、P - gp、
Topo - II 的表达与病人年龄、肿瘤大小无关。GST - π、P - gp 在“Her - 2( + ) 组”及“三阴组”表达率高于“LuminalA
组”的表达率,呈正相关(P < 0. 05)。GST - π 的表达与组织学分级、激素受体表达、乳腺癌的分子分型有
关,有统计学意义(P < 0. 05)。P - gp 的表达与淋巴结转移与否、HER- 2 表达状况、乳腺癌的分子分型呈正相
关(P < 0. 05);Topo - II 与淋巴结转移与否呈正相关(P < 0. 05)。结论:GST - π、P - gp 高表达是乳腺癌多药耐
药发生的高危因素;Topo - II 其表达量的高低与化疗药物作用正相关,与肿瘤的恶性程度正相关。

Objective:Explore the three resistance protein GST - π,P - gp,Topo - II expression in
breast cancer,comparative analysis of a variety of resistance - associated protein in the different clinical
characteristics of breast cancer and different molecular classification of breast cancer tissue expression
of differences,to provide a basis for clinical treatment. Methods:Immunohistochemistry was used to
HRP was detected 60 cases of luminal A subtype;60 cases of Her - 2( + )(containing Her - 2 positive
Luminal B subtype);46 cases of triple negative breast cancer tissue,the expression of GST - π,P - gp
and Topo - II,combined with the pathological features were analyzed. Results:The expression of GST -
π,P - gp,Topo - II with patient age,tumor size,express no statistical significance. The expression of
GST - π,P - gp in the Her - 2( + ) group and the triple negative group expression is higher than Luminal
A subtype rates was positively correlated(P < 0. 05). The expression of GST - π and histological
grade,hormone receptor expression,and molecular classification of breast cancer was positively correlated(
P < 0. 05). The expression of P - gp and lymph node metastasis,HER - 2 expression,molecular
classification of breast cancer was positively correlated (P < 0. 05);The expression of Topo - II and
lymph node metastasis is related to statistically significant(P < 0. 05). Conclusion:GST - π,P - gp
was highly expressed in breast cancer more than to be the resistance occurring risk factors;The expression
level of Topo - II with the chemotherapy drugs was positively correlated,related to a positive correlation
with the degree of malignancy.
