Eight common tumor markers

Carcinoembryonic Antigen (CEA)
        Carcinoembryonic antigen is an acid glycoprotein with the characteristics of human embryonic antigens. It exists on the surface of cancer cells differentiated from endoderm cells and can be detected in serum, cerebrospinal fluid, breast milk, gastric juice, urine, etc. Carcinoembryonic antigen is a marker of tumors such as digestive system tumors, lung cancer, and breast cancer.

Alpha-fetoprotein (AFP)
        Alpha-fetoprotein is a glycoprotein, which is closely related to the occurrence and development of liver cancer and a variety of tumors. In a variety of tumors, alpha-fetoprotein can exhibit higher concentrations and is a marker of primary liver cancer, testicular cancer, ovarian cancer and other tumors.

Carbohydrate Antigen 125 (CA125)
        Carbohydrate antigen 125 is a glycoprotein antigen secreted by epithelial cells of the body cavity, and is a marker for tumors such as ovarian cancer.

Carbohydrate Antigen 153 (CA153)
        Carbohydrate antigen 153 is significantly increased in 30%-50% of breast cancer patients. Carbohydrate antigen 153 is a marker of breast cancer and other tumors.

Carbohydrate Antigen 199 (CA199)
        Carbohydrate antigen 199 is an oligosaccharide tumor-associated antigen. At present, the most sensitive marker for pancreatic cancer is a marker for tumors in the digestive system.

Carbohydrate Antigen 724 (CA724)
        Carbohydrate antigen 724 is currently one of the best tumor markers for the diagnosis of gastric cancer. It has high specificity for gastric cancer and is a marker for gastric cancer, ovarian cancer and other tumors.

Carbohydrate Antigen 242 (CA242)
        Carbohydrate antigen 242 is a sialylated glycosphingolipid antigen, which is a good tumor marker for pancreatic cancer and colon cancer, and is a marker for tumors in the digestive system.

Carbohydrate Antigen 50 (CA50)
        Carbohydrate antigen 50 is a kind of sialic acid ester and sialic acid glycoprotein, which is a marker of tumors such as digestive system tumors, breast cancer, and lung cancer.
