近年来,甲种胎儿蛋白(简称甲胎蛋白)检测已被广泛应用于原发性肝细胞癌的诊断。我国于1970年开始研究甲胎蛋白检测的临床价值。上海市各有关单位至1972年10月共进行4,621例临床检测(表1)。其中临床诊断为原发性肝癌的797例的阳性率为75.65％,经病理检查确诊为原发性肝细胞癌的139例的阳性率为76.3％。 In recent years, detection of alpha fetoprotein (AFP) has been widely used in the diagnosis of primary hepatocellular carcinoma. In 1970, China began to study the clinical value of alpha-fetoprotein detection. A total of 4,621 clinical trials were conducted by various Shanghai units until October 1972 (Table 1). The positive rate of 797 cases with clinically diagnosed primary liver cancer was 75.65%, and the positive rate of 139 cases diagnosed as primary hepatocellular carcinoma by pathological examination was 76.3%.
