Hypothesis
The study aims to evaluate the usefulness of serum CA15-3 in comparison to CEA and TPA for early diagnosis and monitoring of breast cancer relapses.
Conclusion
The study concludes that TPA is the most useful tumor marker in post-operative follow-up of breast cancer patients, with the combination of CA15-3 and TPA providing the best sensitivity for early diagnosis.
Supporting Evidence
- CA15-3 sensitivity for early diagnosis of metastases was 46%, compared to 7% for CEA and 63% for TPA.
- The combination of CA15-3, CEA, and TPA showed a sensitivity of 87% for detecting metastases.
- High serum CA15-3 values were found in 21 out of 40 relapsed patients.
Takeaway
Doctors checked blood markers to see if breast cancer came back after surgery, and found that one marker, TPA, was the best at spotting problems early.
Methodology
The study involved monitoring 285 breast cancer patients post-operatively with serial serum determinations of CA15-3, CEA, and TPA.
Limitations
The study may have limitations related to the specificity of tumor markers and the influence of benign diseases on marker levels.
Participant Demographics
Patients aged 29 to 84 years, with 33.3% premenopausal and 42% with post-operative axillary lymph-node involvement.
