Hypothesis
What is the incidence and prognostic value of disseminated tumor cells in the bone marrow of early breast cancer patients?
Conclusion
Detecting tumor cells in bone marrow can help predict outcomes in early breast cancer patients, but traditional prognostic factors are still very important.
Supporting Evidence
- 22% of patients had disseminated tumor cells in bone marrow.
- 28% of patients had axillary lymph node involvement.
- Simultaneous involvement of lymph nodes and bone marrow was rare.
Takeaway
The study found that some breast cancer patients have tumor cells in their bone marrow, which can help doctors understand how serious their cancer might be.
Methodology
The study involved 104 patients with early breast cancer, analyzing bone marrow for tumor cells and correlating findings with lymph node involvement.
Limitations
The study had a low event rate during follow-up, which may limit the ability to draw strong conclusions about the prognostic value of disseminated tumor cells.
Participant Demographics
Mean age of participants was 55.6 years, with tumor sizes less than 3 cm and clinically negative axillary lymph nodes.
Statistical Information
P-Value
p<0.05 for some associations
Confidence Interval
95% CI = 0.12-13.8 for lymph node involvement
