肺癌的发病率和死亡率近年来世界各国都显著上升,在肺癌的防治工作中,如能早期发现、早期诊断,及早手术和综合治疗,其五年生存率可以大为提高。已经发现癌组织可以产生许多标记物,包括激素、酶、抗原、胚胎蛋白等。就肺癌已探讨过的标记物就有40多种。但迄今除肝细胞性肝癌、胚胎性肿瘤、绒癌、甲状腺髓样癌等少数几种肿瘤已有较满意的免疫诊断方法外,其它多种肿瘤(包括肺癌)还没有有效的免疫诊断方法。不过近年来在肺癌 The incidence and mortality of lung cancer have increased significantly in various countries in the world in recent years. In the prevention and treatment of lung cancer, early detection, early diagnosis, early surgery, and comprehensive treatment can significantly increase the five-year survival rate. It has been found that cancerous tissues can produce many markers, including hormones, enzymes, antigens, embryonic proteins, and the like. There are more than 40 markers that have been explored for lung cancer. However, a few tumors such as hepatocellular carcinoma, embryonal carcinoma, choriocarcinoma, and medullary thyroid carcinoma have been more satisfactory than others. There are no effective immunodiagnostic methods for other types of tumors (including lung cancer). But in recent years in lung cancer
