Colorectal Carcinoma and Blood Loss
Author Information
Author(s): D. Frommer, A. Kapparis
Primary Institution: St. Vincent's Hospital
Hypothesis
Is there a relationship between the stage of colorectal carcinoma and the rate of blood loss?
Conclusion
The study found a tendency for increased blood loss with later stages of colorectal carcinoma in the left hemicolon, but not in the right hemicolon.
Supporting Evidence
- There was a tendency for increased blood loss with later stages of carcinomas in the left hemicolon.
- More bleeding was observed from right-sided than left-sided Stage A carcinomas.
- Markedly reduced bleeding was found from carcinomas in the transverse colon.
Takeaway
Doctors looked at patients with colon cancer to see if the stage of cancer affected how much they bled. They found that later stages bled more, but only on one side of the colon.
Methodology
Patients were screened for colorectal carcinoma using Hemoccult and immunodiffusion techniques, and blood loss was analyzed in relation to Dukes-Astler staging.
Limitations
The differences in bleeding between stages were not very great, and some findings were based on a small number of patients.
Participant Demographics
Patients were largely asymptomatic and included both left and right hemicolon cases.
