摘要: 探讨多药耐药因子在肺癌中表达与共表达的相关性及其临床意义。方法:采用免疫组化SP技术检测52例肺癌患者病理组织中P-糖蛋白(P-gp)、多药耐药相关蛋白(MRP)、谷胱甘肽S转移酶Ⅱ(GST-Ⅱ)3种多药耐药因子的表达水平。结果: 肺癌组织中P-gp、 MRP、GST-Ⅱ阳性表达率分别为51.9% (27/52)、61.5% (32/52)和78.8%(41/52);耐药因子在不同病理类型、不同TNM分期和不同分化程度间表达差异无显著性(P>0.05);P-gp和MRP均阳性40.1%,P-gp和GST-Ⅱ均阳性44.2%,MRP和GST-Ⅱ均阳性50.0%,P-gp、MRP和GST-Ⅱ均阳性21.2%,其中P-gp与MRP间阳性表达率呈正相关关系(rs=0.632,P<0.01),P-gp与GST-Ⅱ间阳性表达率呈正相关关系 (rs=0.521,P<0.01),MRP与GST-Ⅱ间阳性表达率呈正相关关系(rs=0.532, P<0.01)。结论: 肺癌的多药耐药现象是由多个耐药因子共同参与作用的结果,肺癌多药耐药的发生与不同的病理组织类型、不同TNM分期、不同分化程度间无关联

Abstract: To study the levels of expression, coexpression and clinical significance of multidrug resistance factors in lung cancer. MethodsThe expressions of p-glutathione(P-gp), multidrug resistance-associated protein(MRP),glutathione s-transferase Ⅱ(GST-Ⅱ) in tumor tissues of 52 lung cancer patients were detected by using immunohistochemical method. ResultsThe positive rates of P-gp,MRP,GST-Ⅱ were 51.9%(27/52), 61.5%(32/52), 78.8%(41/52), respectively. No relationship was observed between the expression of drug resistance factors and TNM stage and cell differentiation. The coexpression rates were as follows: P-gp+MRP,40.1%;P-gp+GST-Ⅱ,44.2%;MRP+GST-Ⅱ,50.0%;P-gp+MRP+GST-Ⅱ,21.2%;correlations were found between P-gp and MRP(rs=0.632,P<0.01),P-gp and GST-Ⅱ (rs=0.521,P<0.01), MRP and GST-Ⅱ (rs=0.532, P<0.01). ConclusionThe multidrug resistance in lung cancer patients is affected by various multidrug resistance factors. The drug resistance factors’〖KG-*3〗 expressions are not related to histological subtypes, TNM stage and cell differentiation.
