Hypothesis
If PCR measurement of receptor expression is comparable to IHC, it will provide a cheaper and more accessible method for the determination of breast cancer receptor expression.
Conclusion
The study found that qPCR can be used as a reliable alternative to IHC for determining the expression of breast cancer hormonal receptors.
Supporting Evidence
- The study evaluated 20 matched formalin fixed paraffin embedded and RNAlater preserved samples.
- ER and PR were expressed in 60% of the study samples.
- HER-2 was negative in 70% of study samples.
- The mean Ct values for ER, PR, and HER-2 were reported.
Takeaway
This study shows that a simpler test can help doctors find out how much of certain hormones are in breast cancer, which can help in choosing the right treatment.
Methodology
The study evaluated 20 matched breast tissue samples using immunohistochemistry and quantitative PCR to measure the expression of ER, PR, and HER-2.
Potential Biases
Potential bias due to the small sample size and the reliance on a single testing method.
Limitations
The sample size was small, and the study was limited to a single institution.
Participant Demographics
95% female, median age 41 years, with ages ranging from 26 to 72.
