【摘要】 目的观察肺癌患者血清恶性肿瘤特异性生长因子(TSGF)、癌胚抗原(CEA)、唾液酸(SA)含量变化 ,探讨其在肺癌诊断中的价值。方法用生化比色定量法检测TSGF、SA ,用放射免疫法检测CEA。结果肺癌组TSGF、CEA、SA血清水平分别为(82.9±20.5)KU/L、(33.8±19.5)μg/L、(750.7±172.3)mg/L ,显著高于肺良性疾病组和健康对照组(P<0.001)。三者联合检测则诊断阳性率高达100 %。结论TSGF、CEA、SA检测在肺癌诊断中均有意义 ,三项联合检测则具有更重要的诊断价值 ,并可提高其诊断的敏感性和准确性。更多还原

【Abstract】 Objective To investigate TSGF?CEA?SA levels in the serum of lung cancer patients. To aim at studying the values in the diagnosis of lung cancer.Methods To measure TSGF?SA levels in serum with chemical method, CEA levels with radioimmunology. Results The levels of TSGF?CEA?SA in the serum of lung cancer patients were (82.9±20.5)KU/L?(33.8±19.5)μg/L?(750.7±172.3)mg/L. They were significantly higher than those in the serum of malignant patients and normal persons(P<0.001). The positive rate of the combination of the three was 100%. Conclusion They had significant values in diagnosing lung cancer. The combination of detection not only had more valuable but also raised the sensitivity and accuracy in the diagnosis of lung cancer.更多还原
