Cancer antigen 125
Cancer antigen 125, abbreviated CA125 and CA-125, is a common immunostain and serum marker of disease. It is also known as mucin 16 and officially abbreviated MUC16.[1][2]
It is elevated in the serum in ovarian cancer and mildly or moderately elevated in endometriosis.
Positive
- Ovarian carcinoma ~ 75% of cases.[3]
- Serous carcinoma of the ovary ~ 95% of cases.[3]
- Pancreatic ductal adenocarcinoma.[4]
- Epithelioid sarcoma - reported.[5]
Positive or negative
- Cholangiocarcinoma +ve/-ve (30 +ve of 63 cases[6]).
Usually negative
- Breast carcinoma ~15% of cases show weak focal positivity.[3]
