【摘要】 目的　用脂质结合唾液酸 (LSA)与恶性肿瘤特异性生长因子 (TSGF)对肺癌诊断的对比性研究。方法　用改良间苯二酚法和化学比色法 ,同时检测 56例肺癌、65例肺良性疾病、50例健康成人血清中 LSA和 TSGF的含量。结果　在肺癌患者中 ,LSA阳性率为 80 .4% ,诊断正确率为 87.3% ;TSGF阳性率为 85.7% ,诊断正确率为 89.6% ,二者结果相似。33例各型肺癌患者的 LSA和 TSGF水平变化与手术切除疗效相关。结论　 LSA及 TSGF对肺癌疗效监测具有较显著的临床意义。尤其是联合使用 LSA和 TSGF检测用于提高临床肺癌的正确诊断率更具有价值更多还原

【Abstract】 Objective To evaluate the reliability of lipid-bound sialic acid (LSA) and tumor specific growth factor(TSGF) in the diagnosis of lung cancer.Methods The serum LSA and TSGF concentrations were measured in 56 cases of lung cancer,65 cases of benign lung diseases and 50 cases of healthy people by improved resorcinol and colorimetry methods.Results The LSA positive rate was 80.4% in the lung cancer cases;the accuracy was 87.3%.The TSGF positive rate was 85.7% in the lung cancer cancer cases;the accuracy was 89.6%.The results of LSA and TSGF were similar.In addition,the changes of LSA and TSGF concentrations in 33 cases of different types of lung cancer were related to surgery treatment.Conclusion LSA and TSGF are of significance in the observation of lung cancer during treatment.The combined use of LSA and TSGF was more valuable for raising the correct diagnosis rate of lung cancer in clinics.更多还原
