摘  要:目的:探讨促血管生成素2(Ang-2)及其受体Tie-2在非小细胞肺癌组织中的表达及意义。方法:采用免疫组化法分析Tie-2、Ang-2在50例非小细胞肺癌患者(其中腺癌28例,鳞癌22例)组织中的表达。结果:Tie-2、Ang-2在非小细胞肺癌组织中的阳性率分别为52.0%(26/50)、66.0%(33/50);Tie-2、Ang-2在腺癌组织中阳性率分别为67.9%(19/28)、82.1%(23/28),均明显高于其在鳞癌组织中的阳性率[31.8%(7/22)、45.5%(10/22)],差异有统计学意义(P<0.05)。Tie-2的阳性表达与患者性别、吸烟指数、肿瘤分期分级无关(P>0.05);而Ang-2的阳性表达与非小细胞肺癌的分期、分级和患者性别、吸烟指数显著相关(P<0.05)。结论:Tie-2、Ang-2与非小细胞肺癌的发生、发展关系密切,Ang/Tie-2抑制剂可能成为治疗非小细胞肺癌的新型靶向药物。OBJECTIVE:To study the expression of Tie2 and Ang2 in non-small cell lung cancer ( NSCLC) and its clinical significance.METHODS:Immunohistochemistry was used to detect the expression of Tie2 and Ang2 in 50 cases of non-small cell lung cancer(28 cases of adenocarcinoma, and 22 cases squamous cell carcinoma) tissues.RESULTS:The positive expression rates of Tie2 and Ang2 in NSCLC tissues were 52.0%(26/50) and 66.0%(33/50) respectively, as compared with 67.9%(19/28) and 82.1%(23/28) respectively in adenocarcinoma tissues, and all were significantly higher than in squamous cell carcinoma [ 31.8%( 7/22 ) and 45.5%( 10/22 ) ] ( P〉0.05 ) .The positive expression level of Tie2 was independent of gender, smoking index, tumor stage/grade ( P 〈0.05 ); however, the positive expression of Ang2 was was significantly associated tumor stage/grade, gender and smoking index ( P 〈0.05 ) . CONCLUSIONS:Tie2 and Ang2 are closely assoicated with the occurrence and development of non-small cell lung cancer, thus the Ang/Tie-2 inhibitors might be used as the novel targeted drugs for non-small cell lung cancer.
