CA 15-3, for Carcinoma Antigen 15-3, is a tumor marker for many types of cancer, most notably breast cancer. [1] [2] [3] It is derived from MUC1. [4] CA 15-3 and associated CA 27-29 are different epitopes on the same protein antigen product of …

2023年5月30日 · Cancer antigen 15-3 (CA 15-3) is used to monitor response to breast cancer treatment and disease recurrence. The reference range of serum CA 15-3 is less than 30 U/mL. The upper limit of the...

2021年6月14日 · The CA 15-3 (carcinoma antigen) is a tumor marker. It means that it raises in the presence of a malignant tumor. Tumor markers are used in the follow-up of treatment for some types of cancer. The CA 15-3, along with the CA 27-29 and the CEA markers, is used in the follow-up of treated breast cancer. An increase in CA 15-3 concentrations during ...

2021年12月20日 · A CA 15-3 test is performed in order to assess the response of your breast cancer to therapy. It can also be used to detect any recurrence of this disease. Elevated levels of cancer antigen 15-3 are seen in approximately 60% of preoperative breast cancer cases and 80% of widespread metastatic breast cancer cases.

2023年4月5日 · Cancer antigen 15-3, or CA 15-3, is a protein frequently over-expressed in breast cancer. CA 15-3 can be used to monitor response to breast cancer treatment and disease recurrence. The CA 15-3 is measured in the blood and the normal range is less than 30 U/mL.

Breast cancer is the cancer most likely to release CA 15-3, especially in breast cancer that comes back after treatment. Antigens like CA 15-3 that give information about cancer are called tumor markers.

2021年6月14日 · CA 15-3 is a breast cancer–associated antigen that is high in malignant cancer (breast, pancreatic, lung, ovarian, colorectal, or liver cancer) and benign conditions (fibroadenoma, hepatitis, cirrhosis, sarcoidosis, tuberculosis, SLE, hypothyroidism, etc.)
