摘要:

目的 探讨胸腔积液中血管生成素-2(Ang-2)、血管内皮生长因子(VEGF)、癌胚抗原(CEA)对肺癌合并胸腔积液的诊断价值及对不同病理类型肺癌的临床意义。方法 收集胸腔积液患者79例,其中肺癌合并胸腔积液患者43例(鳞癌12例、腺癌20例、小细胞肺癌11例),良性胸腔积液患者36例。采用酶联免疫吸附试验(ELISA)检测胸腔积液中Ang-2和VEGF的水平,放射免疫分析法检测CEA的水平,并比较各指标在肺癌不同病理类型中表达的差异。结果 肺癌合并胸腔积液患者胸腔积液中Ang-2、VEGF、CEA的水平高于良性胸腔积液患者(P<0.05)。腺癌患者胸腔积液中CEA的阳性率高于鳞癌及小细胞肺癌患者(P<0.05),Ang-2、VEGF的阳性率与鳞癌及小细胞肺癌患者比较,差异无统计学意义(P>0.05)。结论 检测胸腔积液中Ang-2、VEGF、CEA的水平对诊断肺癌合并胸腔积液具有临床意义,联合检测可提高诊断效能。CEA对腺癌诊断价值较高,未发现Ang-2和VEGF与肺癌病理分型有关。

Abstract:

Objective To investigate the levels of angiopoietin-2 (Ang-2),vascular endothelial growth factor (VEGF) and carcinoembryonic antigen(CEA) in pleural effusion for the diagnosis of lung cancer with pleural effusion and different pathological types of lung cancer. Methods A total of 79 pleural effusion samples were collected from 43 lung cancer patients with pleural effusion(12 cases of squamous carcinoma,20 cases of adenocarcinoma and 11 cases of small-cell lung cancer) and 36 patients with benign pleural effusion. The levels of Ang-2 and VEGF were determined by enzyme-linked immunosorbent assay(ELISA),and the level of CEA was determined by radioimmunoassay. The levels of different pathological types of lung cancer were compared. Results The levels of Ang-2,VEGF and CEA were higher in lung cancer with pleural effusion group than those in benign pleural effusion group (P<0.05). The positive rate of CEA in adenocarcinoma group was higher than those in squamous carcinoma and small-cell lung cancer groups (P<0.05),but the positive rates of Ang-2 and VEGF had no statistical significance (P>0.05). Conclusions The determinations of Ang-2,VEGF and CEA play roles for the diagnosis of lung cancer with pleural effusion,and the combined determination can improve diagnosis efficiency. CEA is potential for the diagnosis of adenocarcinoma,and there is no correlation of Ang-2 and VEGF with different pathological types of lung cancer.
