  • 專業解析

    癌胚抗原(Carcinoembryonic Antigen, CEA)是一種重要的腫瘤标志物,其詳細解釋如下:

    1. 定義與基本性質 癌胚抗原(CEA)是一種分子量約為180-200 kDa的糖蛋白,屬于免疫球蛋白超家族成員。它主要由胎兒胃腸道、肝髒和胰腺組織合成,在胚胎發育階段表達量較高,但在正常成人組織中表達水平極低或檢測不到。CEA的生理功能尚未完全闡明,但研究表明它可能在細胞間識别、粘附及免疫調節中發揮作用 。

    2. 臨床意義與腫瘤相關性 CEA在多種惡性腫瘤中異常高表達,尤其在結直腸癌的診斷、療效評估和複發監測中具有核心價值:

    3. 檢測與解讀 CEA通過血液樣本檢測(血清或血漿),常用方法為化學發光免疫分析法。健康成人血清濃度通常<5 ng/mL(參考值因實驗室略有差異)。結果解讀需結合臨床:

    網絡擴展資料

    癌胚抗原(Carcinoembryonic Antigen,簡稱CEA)是一種與腫瘤相關的生物标志物,其詳細解釋如下:

    1.基本定義與性質

    CEA是一種酸性糖蛋白,屬于免疫球蛋白超家族成員,具有胚胎抗原特性。它最初在胎兒發育時期的消化道組織(如腸道、胰腺)中表達,出生後正常成人體内含量極低或無法檢出。

    2.生物學功能與來源

    3.臨床意義

    4.曆史與發現

    CEA于1965年由Gold和Freedman首次從結直腸癌組織和胚胎腸黏膜中分離鑒定,成為首個被廣泛研究的腫瘤标志物。

    5.檢測方法

    通過血液、胸腹水、腦脊液等體液檢測,常用技術包括化學發光法、酶聯免疫吸附試驗(ELISA)。
