在过去几年中,已发现许多具有潜在使用价值的肿瘤标记。就肺癌而言,小细胞肺癌有数种敏感性和特异性都较好的标记,如神经元特异性烯醇化酶、B-B肌酸激酶等。但对非小细胞肺癌,已知的标记物(主要是癌胚抗原,CEA)不够敏感。特异性亦差。最近,一些作者研究了鳞状细胞癌抗原(SCCAg)在肺癌诊断及临床 In the past few years, many tumor markers have been found to have potential use. For lung cancer, small cell lung cancer has several markers with good sensitivity and specificity, such as neuron-specific enolase, B-B creatine kinase and so on. However, for non-small cell lung cancer, known markers (mainly carcinoembryonic antigen, CEA) are not sensitive enough. The specificity is also poor. Recently, some authors have studied squamous cell carcinoma antigen (SCCAg) in lung cancer diagnosis and clinical
