本文报告癌抗原(CA125)放射免疫测定50例卵巢良、恶性肿瘤患者和正常女性血清反应的临床价值:20例卵巢恶性肿瘤中,以≤35U/ml为正常值,阳性率为75％(15/20);若以≤65U/ml为正常值,阳性率为60％(12/20)。16例卵巢良性肿瘤中,以≤35U/ml为正常值,阳性率为31％(5/16),若以≤65U/ml为正常值,阳性率为6％(1/16);14例正常女性中CA125值>35U/ml的阳性率为14％(2/14),但无1例>65U/ml。结果表明,CA125放射免疫测定在诊断卵巢恶性肿瘤中有一定意义。 This article reports the clinical value of serum CA125 radioimmunoassay in 50 patients with benign and malignant ovarian tumors and normal women. In 20 ovarian malignant tumors, the positive rate was 75% (15% / 20); If the normal value of ≤ 65U / ml, the positive rate was 60% (12/20). In 16 cases of benign ovarian tumors, the positive rate was 35%, the positive rate was 31% (5/16), and the positive rate was 6% (1/16) if ≤65 U / ml was normal; 14 cases In normal women, the positive rate of CA125> 35U / ml was 14% (2/14), but none of the cases was> 65U / ml. The results show that, CA125 radioimmunoassay in the diagnosis of ovarian cancer has a certain significance.
