Hypothesis
The presence of epithelial cells in bone marrow correlates with the expression of metastatic potential markers in primary breast tumors.
Conclusion
The study found that 31% of breast cancer patients had detectable epithelial cells in their bone marrow, which correlated with the expression of a specific receptor associated with metastasis.
Supporting Evidence
- 31% of breast cancer patients had detectable epithelial cells in their bone marrow.
- Bone marrow positivity was correlated with the expression of the 67 kDa laminin receptor in primary tumors.
- No immunoreactive cells were found in peripheral blood samples before or after surgery.
Takeaway
Doctors can find tiny cancer cells in the bone marrow of some breast cancer patients, which might help them understand how aggressive the cancer is.
Methodology
The study used a pool of five monoclonal antibodies to detect epithelial cells in bone marrow aspirates from breast cancer patients.
Limitations
The study did not find a correlation between bone marrow positivity and conventional clinical parameters like tumor size or lymph node metastasis.
Participant Demographics
The study included 197 patients with primary breast carcinoma, with a high prevalence of small tumors and frequent hormone receptor positivity.
