Cancer antigen 15-3 is a glycoprotein whose antigenic determinant is part sugar and part peptide. Cancer antigen 15-3 is an antigen associated with breast cancer and other malignant tumors. The level of CA15-3 in the serum of breast cancer patients significantly increased, so it plays an essential auxiliary role in diagnosing breast cancer.

Cancer Marker CA15-3 is an essential indicator for monitoring postoperative recurrence, especially for patients with cancer metastasis. Increased serum CA15-3 level indicates local or systemic breast cancer recurrence, and the value is earlier to detect than nuclide examination and clinical examination.

Cancer Marker CA15-3 Antigen

CA15-3 is the most important specific marker of breast cancer. It is the best indicator for breast cancer patients to diagnose and monitor postoperative recurrence and observe the curative effect. The CA15-3 level in 30%-50% of breast cancer patients is significantly increased, and its content change is closely related to the treatment effect. The dynamic determination of CA15-3 is helpful for the early detection of recurrence in patients with stage II and III breast cancer after treatment; when CA15-3 is greater than 100U/ml, the metastatic disease can be considered.

Cancer Marker CA15-3 Test

Cancer antigen 15-3 (CA15-3) was quantified in human serum or plasma by chemiluminescence enzyme immunoassay, increased in breast cancer, often used for breast cancer efficacy observation and prognosis estimation. It has a specific value in the diagnosis and treatment follow-up of breast cancer, but the low sensitivity in the early stage of breast cancer is its deficiency. Metastatic ovarian cancer, colon cancer, liver cancer, bile duct cancer, pancreatic cancer, lung cancer, and bronchial cancer can also increase to varying degrees. In general, the reference value for CA15-3 is <28U/ml.
