2022年4月11日 · A carcinoembryonic antigen (CEA) test measures a specific blood glycoprotein called CEA. It means a protein with a lot of sugars added to it by normal or cancerous cells. Scientists first discovered CEA in 1968 when they isolated extracts of liver metastasized by colorectal cancer and also from normal fetal digestive tract.

2021年11月15日 · A CEA test measures the level of carcinoembryonic antigen (CEA) in the blood or other body fluid. As a type of tumor marker, CEA is an indicator of whether cancer is growing and spreading or diminishing with treatment. It is also known as a CEA assay, CEA blood test and carcinoembryonic antigen test.

2021年4月17日 · CEA is an antigen (small protein) that is found on the surface of colon, rectal, gastric and other types of cancer cells and high levels of CEA can be detected in the blood of some patients with cancer and the developing fetus. The CEA is measured in the blood and the normal range is <2.5 ng/ml in an adult non-smoker and <5.0 ng/ml in a smoker.

2024年12月11日 · CEA is a reliable prognostic biomarker for colorectal cancer recurrence in patients who have undergone surgical resection and adjuvant chemotherapy. A CEA level exceeding 5 µg/L at the time of initial colorectal cancer diagnosis signifies a poor prognosis. However, normalization of elevated CEA levels after surgery does not indicate a poor ...

有研究表明在非小细胞肺癌患者血清中，cea水平明显高于健康人和肺部良性疾病患者 ，且将 cea 双倍界值作为阳性标准时，肺癌的可能性最大，随着肺癌临床分期的增高， cea 水平也呈升高趋势，且 cea 阳性患者远期生存率明显低于 cea 阴性患者 。

2022年10月29日 · Carcinoembryonic antigen (CEA) is a tumor marker found in the blood or in other bodily fluids that can be used to monitor treatment for certain cancers. This article explains what the CEA test is, when it can be helpful in cancer treatment, and how to interpret its results.

2021年3月6日 · Carcinoembryonic antigen (CEA) is a tumor marker measured in a blood test that is high in more than 90% cases of colon and pancreatic cancer. It also can be higher than normal in inflammatory bowel diseases and liver diseases.

3 天之前 · One way they can do that is with a carcinoembryonic antigen test. It measures a protein called CEA in the blood. People with some types of cancers have higher than normal levels of this...

2024年10月24日 · 癌胚抗原 (CEA)是一种肿瘤标志物，他的最大特点就是准确性相对更高。 相较CA19-9、CA125、CA72-4、CA24-2、TGSF等指标都更加准确一些。 所以今天我们就癌胚抗原 (CEA)展开讲一讲。 CEA是一种酸性糖蛋白，最初从结肠癌和胚胎组织中提取，存在于内胚层细胞分化的癌症细胞表面，参与细胞粘附和迁移，是细胞膜的结构蛋白。 在胚胎或胎儿组织中表达，出生后血清中几乎检测不到，正常情况下成年人血浆中CEA水平很低，正常值≤5 ng/mL。 CEA …

2024年10月24日 · CEA是一种酸性糖蛋白，最初从结肠癌和胚胎组织中提取，存在于内胚层细胞分化的癌症细胞表面，参与细胞粘附和迁移，是细胞膜的结构蛋白。 在胚胎或胎儿组织中表达，出生后血清中几乎检测不到，正常情况下成年人血浆中CEA水平很低，正常值≤5 ng/mL。 CEA在多种癌症中过度表达，包括消化系统肿瘤、乳腺癌、卵巢癌、肺癌和胰腺癌，但不具有器官特异性。 因此，作为非特异性肿瘤指标物，常与其他指标联合用于肿瘤筛查和随访，其在肿瘤治疗指导和 …
