卵巢恶性肿瘤至今尚未理想的早期诊断方法。自从发现人类某些肿瘤具有肿瘤相关抗原以来,试图借助免疫学方法,来对恶性肿瘤进行诊断便成为近年来肿瘤研究的重大课题之一。把免疫学的方法用于卵巢恶性肿瘤早期诊断的研究国外已有报道,国内类似研究较少。本文报告用美国CENTOCOR公司提供的癌抗原(CA125)放射免疫测定药盒对20例卵巢恶性肿瘤 Ovarian malignancy has not yet been an ideal early diagnosis. Since some human tumors have been found to have tumor-associated antigens, trying to diagnose malignant tumors by immunological methods has become one of the major topics in tumor research in recent years. The use of immunological methods for the early diagnosis of ovarian cancer has been reported abroad, less researches in China. This article reports the use of the United States CENTOCOR company provides cancer antigen (CA125) radioimmunoassay kit for 20 cases of ovarian cancer
