Hypothesis
Can sensitive assays for certain mRNAs be used to detect submicroscopic lymph node metastases in breast cancer patients?
Conclusion
The studied mRNA markers were not useful for detecting submicroscopic lymph node metastases in breast cancer patients.
Supporting Evidence
- The RT-PCR assays were tested against lymph nodes from non-cancer patients to determine their specificity.
- High sensitivity RT-PCR assays for certain mRNAs were not useful as markers of submicroscopic disease.
- The expression of MUC1 was found to be both insensitive and non-specific.
Takeaway
The researchers tried to find special markers in breast cancer patients' lymph nodes, but the tests didn't work well because the markers were also found in healthy people.
Methodology
Sensitive assays for specific mRNAs were developed and tested using RT-PCR on lymph nodes from cancer and non-cancer patients.
Limitations
The markers were tested against a control population, but they were found to be non-specific and insensitive.
