Five tumor indicators

The five tumor markers refer to five blood test indicators used for auxiliary diagnosis of tumors, including carcinoembryonic antigen, alpha fetoprotein, carbohydrate antigen 125, carbohydrate antigen 19 - 9 and prostate specific antigen. CEA is not specific for the diagnosis of cancer, but its dynamic monitoring is helpful to judge the progression, treatment effect and recurrence of cancer. If CEA continues to rise after treatment, it may indicate recurrence or metastasis of cancer. 2. Alpha fetoprotein (AFP) is closely related to liver cancer and is one of the important indicators for the diagnosis of primary liver cancer. For patients with chronic liver disease, AFP elevation should be paid special attention to. However, some germ cell tumors may also cause AFP elevation.(CA 125) is often significantly increased in ovarian cancer patients and can be used for screening and monitoring ovarian cancer. At the same time, it may also be increased to a certain extent in other gynecological diseases and peritoneal diseases.(CA199) has certain suggestive significance for pancreatic cancer, cholangiocarcinoma, etc. Its elevation can also be seen in malignant tumors and some benign diseases in other parts of the gastrointestinal tract. 5. Prostate specific antigen Prostate specific antigen (PSA) is an important marker of prostate cancer and has important value in early diagnosis and monitoring of prostate cancer. However, benign lesions such as prostatitis and benign prostatic hyperplasia may also lead to a mild increase in PSA. It should be noted that the detection results of the five tumor indicators are only one of the basis for auxiliary diagnosis, and cannot be solely determined by these indicators. If these indicators are abnormally elevated, comprehensive judgment should be made in combination with clinical symptoms, signs, imaging examinations, etc., and further pathological examination should be performed if necessary to confirm the diagnosis. At the same time, these indicators cannot completely exclude the possibility of tumor within the normal range.

In clinical practice, five tumor markers should be reasonably applied to assist the diagnosis and treatment of tumors.
