1965年GOld 等发现结肠癌存在一种特异性抗原一癌胚抗原(CEA),嗣后Lo Gerfo,Laurence,平井等认为,由内胚层组织发生的恶性肿瘤患者的血中亦广泛存在CEA。肺癌患者血中CEA 阳性率较高,本文对肺癌手术患者血CEA 值的临床意义加以研究。1978年～1980年的3年中,接受手术治疗的原发性肺癌57例,(男2性48例,女性9例),年龄30岁～73岁,平均60岁。其中鳞癌21例,腺癌26例,大细胞癌9例,小细胞癌1例。根据pTNM 分期:Ⅰ期
In 1965, GOld et al. found that there is a specific antigen-carcinoembryonic antigen (CEA) in colon cancer, and Lo Gerfo, Laurence, Hirai et al. believe that CEA is also widely present in the blood of patients with malignant tumors in endoderm tissue. The positive rate of CEA in the blood of patients with lung cancer is high. This article studies the clinical significance of blood CEA values in patients with lung cancer. In the three years from 1978 to 1980, 57 primary lung cancer patients received surgery (48 males and 48 females), aged 30 to 73 years, with an average age of 60 years. There were 21 cases of squamous cell carcinoma, 26 cases of adenocarcinoma, 9 cases of large cell carcinoma, and 1 case of small cell carcinoma. According to pTNM stage: Phase I
