Hypothesis

Circulating immune cells potentially indicate breast cancer status.

Conclusion

Circulating CD3+CD8+ CTL levels are promising biomarkers for breast cancer management.

Supporting Evidence

  • Circulating CD3+CD8+ CTL levels were lower in breast cancer patients compared to healthy controls.
  • Post-treatment, CD3+CD8+ CTL levels increased, then decreased upon recurrence.
  • Elevated plasma CCL2 levels distinguished breast cancer patients from healthy controls.

Takeaway

Doctors can check certain blood cells to see how breast cancer is doing and if treatment is working.

Methodology

Flow cytometry was used to analyze circulating immune cell profiles in breast cancer patients and healthy controls.

Limitations

The study had a relatively small patient cohort and interindividual variation in immune cell types.

Participant Demographics

Median age of healthy controls was 40 years, and 52 years for breast cancer patients.
