Hypothesis
What is the relationship between prostacyclin and thromboxane production and steroid receptor status in breast cancer?
Conclusion
Breast cancer produces more prostacyclin and thromboxane than mastopathy, but this does not seem to indicate metastatic potential.
Supporting Evidence
- Breast cancer produced more 6-keto-PGFlalpha and TxB2 than mastopathy.
- The production of prostanoids was not related to steroid receptor status.
- MPA did not affect the production of PGI2 and TxA2 in breast cancer tissue.
Takeaway
Breast cancer makes more of certain substances than benign breast tissue, but this doesn't help predict if the cancer will spread.
Methodology
Tissue samples from breast cancer and mastopathy were superfused in vitro to measure prostacyclin and thromboxane production.
Limitations
The study may not account for all factors influencing metastasis and prostanoid production.
Participant Demographics
23 patients with ductal adenocarcinoma and 10 with benign mastopathy, average age 60.4 years.
