CEA 是一种具有人类胚胎抗原特异性的酸性糖蛋白，于 1965 年由 Gold 和 Freedman首先从结肠癌和胚胎组织中提取的一种肿瘤相关抗原，随后在多种其他类型的肿瘤患者、有多年吸烟史的人群或有某些其他非恶性疾病患者的血液中均可检测到 CEA 的浓度升高。 其生理来源通常来源于胎儿的胚胎内胚层上皮，受胎儿致癌基因控制，常在出生后从血清中消失，然而，少量的 CEA 可能残留在结肠组织中，CEA及其相关基因（29个中其中18个正常表达）构成了人类的CEA家族， …

Carcinoembryonic antigen (CEA) describes a set of highly-related glycoproteins involved in cell adhesion. CEA is normally produced in gastrointestinal tissue during fetal development, but the production stops before birth. Consequently, CEA is usually present at very low levels in the blood of healthy adults (about 2–4 ng/mL). [2]

Carcinoembryonic antigen (CEA) is a significant biomarker widely utilized in oncology. This glycoprotein plays a crucial role in cell adhesion and functions as a marker in various cancers. Recognizing CEA levels can provide invaluable insights in the diagnostic process and treatment management of cancer.
