Objective: To study the diagnostic value of combined detection of the 3 tumor markers, namely tissue polypeptide specific antigen (TPS), cancer antigen 153 (CA153), and carcino embryonic antigen (CEA), in patients with breast cancer.
Methods: The serum levels of TPS, CA153 and CEA were determined by enzyme-linked immumosorbent assay in 90 patients with breast cancer and 30 healthy adults.
Results: The serum levels of 3 tumor markers in breast cancer patients were significantly higher than those in the control group (P<0.01). The sensitivity of TPS to breast cancer was 87.7% with specificity of 90.0%. The sensitivity and specificity of CA153 to breast cancer was 55.6% and 93.3%, and those of CEA was 45.8% and 96.7%, respectively. The sensitivity of the 3 tumor markers in combination was 100% in breast cancer diagnosis.
Conclusion: TPS, CA153 and CEA have diagnostic value in breast cancer and possess obvious complementarity, and their combined detection can significantly improve the sensitivity of breast cancer diagnosis.
