肿瘤标志物的检测目前已成为恶性肿瘤诊断的第三支柱,同时对于恶性肿瘤的人群普查、疗效观察、复发监测和预后的判断均有重要作用,故寻求敏感性强、特异性高的肿瘤标志物为目前临床研究的课题。本文试以CA_(50)为消化系肿瘤的标志物,采用免疫放射法(IRMA)测定CA_(50)值的改变,探讨血清CA_(50)对消化系肿瘤的诊断价值。
The detection of tumor markers has now become the third pillar of the diagnosis of malignant tumors. At the same time, it has an important role in population screening, curative effect observation, recurrence monitoring, and prognosis evaluation of malignant tumors. Therefore, it seeks tumor markers with high sensitivity and specificity. The subject is the subject of current clinical research. In this study, CA_(50) was used as a marker of digestive tumors. The change of CA50 value was determined by immunoradiometric assay (IRMA). The diagnostic value of serum CA 50 in digestive system tumors was explored.
