CEA levels in active and non-active malignant tumors

Y Horn, N Walach, J L Zeidman

    Neoplasma
    |January 1, 1982
    PubMed
    Summary

    Carcinоembryonic antigen (CEA) levels accurately reflect cancer activity in patients. Normal CEA indicates non-active disease, while elevated levels suggest active disease, aiding clinical decisions.

    Area of Science:

    • Oncology
    • Clinical Chemistry

    Background:

    • Carcinоembryonic antigen (CEA) is a tumor marker used in cancer management.
    • Monitoring CEA levels is crucial for assessing disease activity and treatment response.

    Purpose of the Study:

    • To evaluate the accuracy of serum CEA levels in correlating with the activity of various neoplasms.
    • To determine the utility of CEA monitoring in clinical decision-making during cancer patient follow-up.

    Main Methods:

    • Serum samples from 283 cancer patients with diverse primary tumor sites were analyzed.
    • 895 Carcinоembryonic antigen (CEA) estimations were performed during patient follow-up or treatment.
    • Disease activity was concurrently assessed using objective laboratory and clinical parameters.

    Main Results:

    • A high accuracy rate was observed for normal CEA values in patients with non-active disease.
    • Elevated CEA values demonstrated high accuracy in identifying patients with active disease.
    • The study confirmed a strong correlation between CEA levels and neoplastic disease activity.

    Conclusions:

    • Serum Carcinоembryonic antigen (CEA) levels are a valuable tool for monitoring cancer activity.
    • CEA monitoring aids in clinical decision-making, but false positive/negative results must be considered.
    • The correlation between CEA and disease activity is significant across various neoplasms.
