Tumor markers in the diagnosis and prognosis of breast cancer

: Serum levels of markers--mucinoid associated antigen (MAA), carcinoembryonal antigen (CEA) and carbohydrate antigen (CA-19-9) were measured in 78 breast cancer patients using enzyme immunoassay. It was found that MAA was most reliable of the above markers in staging breast cancer. A combined study of the latter is advisable in determination of breast cancer dissemination, in the control over the disease course and prognosis.
