The level of carcinoembryonic antigen (CEA) is often elevated in the serum of patients with cancer. This article reviews the clinical usefulness of this observation. Carcinoembryonic antigen is not useful for detecting asymptomatic cancer; its sensitivity and specificity are not high, particularly for early stages of disease, so in populations with low

Heterogeneity of the carcinoembryonic antigen
Immunochemistry, 1973Abstract Fractionation of carcinoembryonic antigen (CEA) by ECTEOLA-cellulose chromatography and by isoelectric focusing indicated that the antigen was heterogeneous. The fractions obtained were variable in their content of sialic acid, amino sugars, and amino acids.

Studies on Carcinoembryonic Antigen
International Archives of Allergy and Applied Immunology, 2009The presence of carcinoembryonic antigen (CEA) in saline extracts (SE) prepared from adenocarcinomas of the colon has been confirmed. This antigen was also detected in perchloric acid extracts (PAE) and in boiled and ethanol precipitated extracts (BE) of colonic tumors. CEA was present in BE preparations of feces from 4 of 8 patients with colon cancer.

Carcinoembryonic antigen in osteosarcoma
Journal of Surgical Oncology, 1977AbstractPlasma carcinoembryonic antigen (CEA) assay was done in 30 patients with osteosarcoma. CEA was found positive (> 2.5 ng/ml) in 17 of 21 patients who had active evidence of disease and negative (< 2.5 ng/ml) in all 9 patients who were in complete remission resulting from previous amputation or chemotherapy.

The antigenicity of carcinoembryonic antigen in man
International Journal of Cancer, 1975AbstractBinding of globulins to 125I CEA was detected in 10 of 24 sera from patients with cancer, 13 of 26 sera from blood donors, and 7 of 27 supernates of tumor‐cell suspensions. Binding was predominantly by IgM in 10 of 14 sera tested by radioimmunoelectrophoresis.

Carcinoembryonic Antigen Revisited
Annals of Internal Medicine, 1973Excerpt A recent editorial in this journal (1) reviewed the relatively brief history of carcinoembryonic (CE) antigen and indicated the increasing interest in this glycoprotein and its potential im...
