作者对716例肿瘤病人进行癌胚抗原(CEA)的测定,其中良性肿瘤149例(21%),恶性肿瘤567例(79%)。发现血浆 CE-A 值>5.0ng/ml 者占良性肿瘤的11%(16/149),占恶性肿瘤的41%(233/567),两者共计249例。其中(血浆 CEA 值>5.0ng/
The authors determined the carcinoembryonic antigen (CEA) in 716 cancer patients, including 149 benign tumors (21%) and 567 malignant tumors (79%). It was found that plasma CE-A values >5.0 ng/ml accounted for 11% (16/149) of benign tumors and 41% (233/567) of malignant tumors, with a total of 249 cases. Among them (plasma CEA value >5.0ng/
