Hypothesis
The expression of pS2 protein increases from normal to benign to cancerous breast cells.
Conclusion
The study found that pS2 is expressed in both invasive and pre-invasive forms of breast cancer, with significant positivity in 63-67% of ductal carcinoma in situ cases.
Supporting Evidence
- pS2 expression was found in 63-67% of ductal carcinoma in situ cases.
- Significant pS2 positivity was observed in about 50% of benign proliferative conditions.
- pS2 was correlated with the presence of progesterone receptor positive cells.
Takeaway
This study looked at a protein called pS2 in breast cancer and found that it shows up more in cancer cells than in normal cells.
Methodology
The study used immunohistochemical techniques on archival paraffin-embedded tissue samples from patients diagnosed with ductal carcinoma in situ.
Limitations
The study had a small sample size and relied on archival material, which may not represent current cases.
Participant Demographics
Patients diagnosed with ductal carcinoma in situ, with a total of 47 biopsies examined.
