However, scientific research and clinical practice have confirmed that with the increase of CA 199, the diagnostic positive rate of pancreatic cancer is only about 70%, and the diagnosis can only be made if it is significantly increased. That is to say, only 70% of all people diagnosed with elevated CA 199 were diagnosed with pancreatic cancer. The simple increase of CA 199 can also appear in many benign diseases, such as acute pancreatitis, cholecystitis, cholestatic cholangitis, liver cirrhosis, hepatitis and so on. Can be used for improving immunity and preventing tumor.
CA 125 is a marker of ovarian cancer and endometrial cancer, and the normal reference range is
The serum concentration of CA 125 is slightly increased, which can be seen in menstrual period, benign ovary or gynecological diseases of a few healthy women.
CA 15-3 is the most important specific marker of breast cancer. 30%-50% of breast cancer patients have significantly increased CA 15-3, and the change of its content is closely related to the curative effect, which is the best index for breast cancer patients to diagnose and monitor postoperative recurrence and observe the curative effect. The dynamic determination of CA 15-3 is helpful for the early detection of recurrence in patients with stage ⅱ and ⅲ breast cancer after treatment. When CA 15-3 is greater than 100U/ml, it can be considered that there are metastatic lesions.
