Abstract
CONDORI FLORES, Liz Nela and MAMANI GARABITO, Jhanneth. CA 15-3 and CEA markers in the breast. Gac Med Bol [online]. 2025, vol.48, n.2, pp.102-106. Epub Dec 31, 2025. ISSN 1012-2966. https://doi.org/10.47993/gmb.v48i2.1000.
Breast cancer is a leading cause of morbidity and mortality in women worldwide. Its occurrence is linked to demographic, reproductive, and lifestyle factors, making it essential to strengthen early detection and clinical follow-up strategies. The tumor markers CA 15-3 and CEA are used to assess tumor activity and support disease management.
Objective:
to determine the tumor markers CA 15-3 and CEA in breast cancer patients at the National Cancer Institute of Cochabamba, Bolivia. Methods: This was a quantitative, descriptive, and correlational study with a non-experimental, cross-sectional design. The study included 89 patients diagnosed with breast cancer who attended the National Cancer Institute.
Results:
27.0% of patients tested positive for the CEA marker, and 20.2% tested positive for CA 15-3. Regarding sex, 25.8% of women tested positive for CEA and only 1.1% of men. For CA 15-3, 19.2% of women showed elevated levels and 1.0% of men; no significant correlation was found between sex and tumor markers. The 41-50 age group was more frequently affected, reflecting tumor activity rather than age.
Conclusion:
The CA 15-3 and CEA markers are useful in the clinical follow-up of breast cancer patients; however, no statistically significant correlation was found with the variables evaluated.
Keywords : carcinoembryonic antigen; breast neoplasms; biological tumor markers.
