Hypothesis
The study aims to measure the levels of enzymes involved in the metabolism of 5-fluorouracil in normal and malignant colorectal tissue.
Conclusion
The study found that levels of certain enzymes responsible for metabolizing 5-fluorouracil are significantly higher in malignant colorectal tissue compared to normal tissue.
Supporting Evidence
- Enzyme levels in malignant tissue were significantly higher than in normal tissue.
- PRT levels showed a wide range in normal tissue but were elevated in malignant tissue.
- UK levels were also found to be elevated in malignant colorectal tissue.
Takeaway
Doctors looked at how certain enzymes work in cancer tissue compared to normal tissue to understand why some cancer treatments don't work well.
Methodology
The study involved measuring enzyme levels in matched normal and malignant colorectal tissue samples from patients.
Limitations
The study does not provide information on the sensitivity of individual tumors to 5-FU treatment.
Participant Demographics
28 patients with primary malignant lesions of the colorectum, 17 males and 11 females, mean age 67.3 years.
