糖类抗原CA50放射免疫抑制试验在肿瘤诊断中的价值

The Diagnostic Value of the Carbohydrate Antigen CA50 on the Malignant Tumors

摘要: 本文报道我院用CA50IRMA测定45名正常人和201树非肿瘤患者及3.36例恶性肿瘤患者血清CA50含量。正常值为＜20ku/L, 肝癌、肠癌、肺癌的CA50值明显升高(P＜0.01), 阳性率分别为79.1%(53/67)、36.4%(16/44、34.9%(29/83)。从初步研究结果显示, CA50值的测定对恶性肿瘤的诊断有一定的价值。

Abstract: The carbohydrate antigen CA50 was examined in serum level of 45 normal persons, 201 pa-tients with benign diseases and 336 patients with malignannt tumor by immumoradiometric assay (IRMA). The results showed that the mean CA50 value in the patients with liver cancer, colon can-cer and lung cancer was much higher then that in the nomal control group (P<0.01). Taking 20ku/L as the upper limit of nomal range, the positive rate were 79.1%(53/67) of patients with liver cancer. 36.4%(16/44) in colon cancer, 34.9%(29/83) in lung cancer. From these results, we concluded that the measurement of level of serum CA50 may be an useful marker for malignant tu-mors diagnosis.
