近年由于应用放射免疫法测定癌胚抗原(CEA),发现在结肠癌或非结肠性肿瘤肝转移时血清中CEA常明显增高。为了比较CEA试验及肝扫描对诊断肝转移肿瘤的价值,作者对377例都做过CEA试验及肝扫描的患者进行了分析。观察9～15个月,其中185例已知或疑有原发性肿瘤,192例临床并不疑有肿瘤。分析结果见表1。 In recent years, due to the application of radioimmunoassay to measure carcinoembryonic antigen (CEA), it has been found that serum CEA often increases significantly in the liver metastasis of colon cancer or non-colonic tumor. To compare the value of CEA and liver scans in the diagnosis of liver metastases, the authors analyzed 377 patients who had undergone both CEA and liver scans. Observed 9 to 15 months, of which 185 were known or suspected primary tumors, 192 cases of clinically no doubt tumors. The results of the analysis are shown in Table 1.
