Hypothesis
Can the combination of 5-fluorouracil and folinic acid improve cancer treatment outcomes?
Conclusion
The combination of 5-fluorouracil and folinic acid shows improved efficacy compared to 5-fluorouracil alone in treating certain cancers.
Supporting Evidence
- The combination of 5-fluorouracil and folinic acid has shown a significantly higher response rate in several trials.
- One phase II trial reported a 50% objective response rate in patients with advanced gastric carcinoma.
- Phase III trials have shown significant prolongation of overall survival in colorectal carcinoma patients treated with the combination.
Takeaway
Doctors are trying to use two medicines together to help people with cancer get better results than using just one medicine.
Methodology
The article reviews various phase I/II and phase III clinical trials comparing 5-fluorouracil alone versus in combination with folinic acid.
Limitations
There are no mature phase III trials specifically for gastric carcinoma, and the survival benefits of the combination treatment are relatively minor.
Participant Demographics
Patients with advanced gastric carcinoma, breast cancer, and colorectal carcinoma.
