Hypothesis
What is the prognostic significance of the S-phase fraction in breast cancer?
Conclusion
The S-phase fraction is a significant prognostic factor in breast cancer, contrary to the claims of some studies.
Supporting Evidence
- The S-phase fraction has been shown to correlate with treatment response in breast cancer.
- Previous studies indicate that the proliferative activity of breast cancers is an important biological determinant of outcome.
- Discrepancies exist between the conclusions of some studies and the broader literature on S-phase fraction.
Takeaway
Doctors are trying to figure out how to tell if breast cancer will get worse by looking at how fast the cancer cells are growing.
Methodology
The commentary discusses the interpretation of DNA histograms by experienced cytometrists.
Potential Biases
There may be biases in the interpretation of results due to differing opinions among cytometrists.
Limitations
The subjective interpretation of DNA histograms may limit the effectiveness of DNA flow cytometry.
