放射免疫分析是国际上60年代发展起来的一种超微量分析技术,人绒毛膜促性腺激素双抗体放射免疫测定(hcG RIA)具有很多优点,其灵敏度高、专一、性能稳定且能定量等。此法对绒毛膜癌和葡萄胎的早期诊断和治疗动态观察有较高价值。我院自1980年开始应用血hcG放射免疫测定于临床至1982年止,两年内共收治滋养细胞肿瘤70例(其中恶性葡萄胎27例,绒毛膜癌8例,良性葡萄胎35例),现小结如下: Radioimmunoassay (RIA) is an ultra-trace analysis technology developed in the 1960s. Human chorionic gonadotrophin dual-antibody radioimmunoassay (hcG RIA) has many advantages, such as high sensitivity, specificity, stable performance and quantitation . This method for chorionic cancer and hydatidiform mole early diagnosis and treatment of dynamic observation of high value. Our hospital since 1980, the application of blood hcG radioimmunoassay in clinical until 1982, within two years were treated 70 cases of trophoblastic tumors (including 27 cases of malignant mole, choriocarcinoma in 8 cases, 35 cases of benign hydatidiform mole), and now The summary is as follows:
