运用免疫组化技术对48例肺脏疾患中的结肠单克隆抗体(MC_3)及癌胚抗原(CEA)进行了检测。发现MC_3及CEA对肺脏恶性肿瘤的诊断价值优于良性病变。MC_3及CEA还与肺癌的分化程度有关。
Immunohistochemistry was used to detect colonic monoclonal antibody (MC_3) and carcinoembryonic antigen (CEA) in 48 lung diseases. It was found that MC_3 and CEA were superior to benign lesions in the diagnosis of lung cancer. MC_3 and CEA are also related to the degree of differentiation of lung cancer.
