原发性肺癌的发病率居恶性肿瘤之首，早期发现是提高治愈率和生存率的关键。对可疑患者进行筛检是早期诊断的保证。免疫学检测在肺癌早期筛检和诊断方面较其它方法有不可比拟的优点。起初用单株肺癌单克隆抗体对患者进行检测，特异性虽高，但灵敏度很差，不利于筛检患者。我们? The incidence of primary lung cancer ranks first among malignant tumors. Early detection is the key to improving the cure rate and survival rate. Screening for suspicious patients is a guarantee of early diagnosis. Immunological testing has unparalleled advantages over other methods in the early screening and diagnosis of lung cancer. Initially, single-plant lung cancer monoclonal antibodies were used to detect patients. Although the specificity was high, the sensitivity was poor and it was not conducive to screening patients. we?
