Hypothesis
How does surgery affect the level of circulating epithelial cells in breast cancer patients?
Conclusion
Epithelial cells are frequently mobilized into circulation during breast cancer surgery, and some may remain dormant and contribute to metastasis over time.
Supporting Evidence
- Circulating epithelial cells were present before surgery in all patients.
- 85% of treated patients showed an increase in circulating epithelial cells after surgery.
- Cell numbers remained elevated in some patients for up to three years without signs of relapse.
Takeaway
When doctors operate on breast cancer, some tiny cells can get into the blood. These cells might stay there for a long time and could cause more problems later.
Methodology
The study monitored circulating epithelial cells in breast cancer patients before and after surgery using MAINTRAC® analysis.
Limitations
The study could not distinguish between benign and malignant epithelial cells.
Participant Demographics
Patients included 52 consecutive individuals with newly diagnosed breast cancer of various stages.
