Hypothesis
Does surgical trauma to the colon enhance the growth of bloodborne cancer cells?
Conclusion
Surgical trauma enhances the growth of bloodborne cancer cells in the colon, especially when the trauma occurs before the injection of the cancer cells.
Supporting Evidence
- Maximum enhancement of tumor growth occurred when healing progressed between 2 and 8 days after surgery.
- Cells injected into the colon after surgery did not lead to tumor growth.
- The chance of a cancer cell leading to a tumor deposit at an anastomosis is 1 in 43.
Takeaway
When doctors operate on the colon, it can help cancer cells grow better if the surgery happens before the cancer cells are injected.
Methodology
Hooded Lister rats were used to study the effects of surgical trauma on tumor growth from injected cancer cells.
Limitations
The study was limited to specific types of cancer cells and the effects of timing were not fully explored for all scenarios.
Participant Demographics
Hooded Lister rats, both male and female, weighing between 150-300g.
