患者癌胚抗原(CEA)增高,到底有没有得肿瘤?_腾讯新闻
2023年5月21日 · CEA,1965 年由 Gold 和 Freedman 发现,是一种由粘膜细胞表达的糖蛋白,是一种肿瘤相关抗原,它不仅在结直肠癌等多种恶性肿瘤中过度表达,在一些良性疾病和药物作用下也可出现过度表达,具体如下: 由此可见,CEA 增高未必与肿瘤相关,但是,良性疾病导致的血清 CEA 升高很少超过 10 ng/mL。 当然,这也并不是说 CEA 不超过 10 ng/mL,肿瘤就一定不存在。 虽然,CEA 不是一个很好的肿瘤筛查工具,但是当 CEA 升高时,我们又不能置之不理。 …
细说肿瘤标志物之癌胚抗原(CEA) - 知乎
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, …
