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.

2024年12月11日 · Carcinoembryonic antigen (CEA) is a nonspecific serum biomarker that is elevated in many malignancies, including colorectal cancer, medullary thyroid cancer, breast cancer, and mucinous ovarian cancer.

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.

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.

cea 属于称为 cea 相关细胞粘附分子 (ceacams) 的免疫球蛋白家族，cea 与内皮细胞的各种功能密切相关，包括细胞在体内和体外的粘附、增殖和迁移。它存在于正常细胞细胞膜的腔内侧，被认为可以抑制细胞凋亡，因此参与肿瘤发病机制。

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.

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.

2024年4月30日 · The Carcinoembryonic Antigen (CEA) blood test is a diagnostic tool used to measure the level of CEA, a protein that can be elevated in certain types of cancer. This test is primarily associated with monitoring colorectal cancer but can also provide insights into other cancers and health conditions.

2017年5月13日 · What is CEA tumor marker? CEA – Carcino Embryonic Antigen is a tumor marker. Tumor markers are substances produced by cell- either normal or cancer cells. Normal cells produce tumor markers in much lower levels as cancer cells. For this reason, elevated levels of tumor marker can be a sign of cancer.
