癌胚抗原(CEA)是一种由结肠癌组织提取,分子量为20万的糖蛋白,自1965年由Gold等发现以来,现已广泛用于临床。1986年10月～1987年10月我们测定了65例肺癌患者的血清CEA值,与肺部良性病变及正常人作对照。结果表明CEA对肺癌的诊断,疗效观察,预后判断有一定参考价值。 材料与方法 一、检测对象 1.肺癌组65人,男49人,女11人,年龄26～77岁,平均53.2岁。其中鳞癌29例,腺癌17例,小细胞未分化癌11冽,大细胞未分化癌3例,粘液表皮样癌1例,未明确分类4例。
Carcinoembryonic antigen (CEA) is a kind of glycoprotein with a molecular weight of 200,000, which is extracted from colon cancer tissue. Since it was discovered by Gold et al. in 1965, it has been widely used clinically. From October 1986 to October 1987, we measured serum CEA levels in 65 patients with lung cancer, compared with benign lung lesions and normal controls. The results show that CEA has certain reference value for the diagnosis, efficacy observation and prognosis of lung cancer. Materials and methods First, the test object 1. Lung cancer group of 65 people, 49 males and 11 females, aged 26 to 77 years, mean 53.2 years old. Among them, there were 29 cases of squamous cell carcinoma, 17 cases of adenocarcinoma, 11 cases of small cell undifferentiated carcinoma, 3 cases of large cell undifferentiated carcinoma, 1 case of mucoepidermoid carcinoma, and 4 cases not clearly classified.
